Vegetarians (素食者) around the world have long believed that a vegetarian diet is a healthier choice than a meat-based one. Studies have shown that not only do vegetarians have less heart disease and fewer circulatory problems, but they also tend to have fewer chances of cancer.   36 

Should you consider becoming a vegetarian you may wonder:   37   The term “Vegetarian” generally describes a person who does not consume meat, fish, or seafood. However, there are several types of vegetarians, and the vegetarian diet can change depending on which category the person falls into.

  38   Today’s importance on meat-centred diets has been proved to contribute to many of our modem illnesses. Choosing to get rid of or limit the meat you eat can bring you many of the health benefits of a vegetarian diet. In addition to the health benefits of a vegetarian diet, you will also reduce your share of the suffering that human beings bring to animals.

Many people start vegetarian diets without doing nutritional research and learning what a balanced vegetarian diet makes up. As a result, a large number of new vegetarians complain that they lack energy.   39   Others find quite a few other problems that come with a poorly balanced vegetarian diet.

Not everyone wants to be a vegetarian. Accepting this is part of being a vegetarian with style.   40   Stylish vegetarians should also be able to turn down a meaty dish politely without annoying their hosts.

A. What do vegetarians eat?

B. The benefits of a vegetarian diet are many.

C. Forcing your beliefs on others is disrespectful.

D. Meal planning is important whatever diet you choose.

E. A balanced vegetarian diet can’t make sure health alone.

G. It’s no wonder that more and more people turn to vegetarian diets.

The Depression was still going on, but I was in good spirits. I was going to graduate from elementary school, yet my mother   36   dressed me in shorts. Most of my classmates had given up   37   shorts. For the graduation ceremony, all the boys were   38   to dress the same way-white shirts and dark-blue wool pants.

   I waited until a week before I told my mother. I   39   I’d better break the news to her as gently as I could.

“Mom,” I said, “about   40   …”

“Yes?” she answered.

“They’re going to give me the first –prize medal,” I said.

She looked   41   her shoulder at me and smiled. “That’s wonderful, Babe. Dad and I will both be there, and we’ll be the   42   parents in the place.”

She must have seen by the look on my face that   43   was wrong. She turned her back and said, “So?”

“So, I have to get   44   pants, ” I said.

“Babe, we don’t have the   45   for new pants right now,” she said very quietly, “You know that.”

“Ok,” I burst out. “Then I won’t go to graduation. Plus, I’m   46   away from home!” 

The following Saturday, when my mother said, “Let’s go shopping,” I knew she had   47   the problem. We walked a short way and stopped at a place I had never   48   before. My mother said, “  49   here,” She entered a storefront that looked like a   50   . She came out about ten minutes later, and we went to the pants store. I was holding the new pants   51  under my arm when my mother went to pay for it. I saw her   52   a tiny brown envelope from her purse. There were four   53   new one-dollar bills inside.

About halfway home, I   54   down at my mother’s hands. It was then that I saw the wedding ring that had always circled her ring finger was   55   there.

We were on our way home from Houston one Saturday morning. We decided to stop at a local gas station to get coffee and something to snack on since it was a good hour and a half before we got home.
    When we were done, we got back into our car and before I started it,  we noticed a man standing outside in front of the building. He was a homeless man with worn clothes and it looked like he had gone in and gotten himself some coffee or something warm to drink since it was cold this time of the year. He must have not had enough money to get something to eat.
    Then a dog walked up to the front of the building. I could tell she was a “she”, because you could tell that she had baby dogs. She was terribly in need of something to eat and I felt so bad for her. I knew if she didn’t eat soon, she and her baby dogs would not make it.
    I and my wife sat there and looked at her. We noticed that people walked by and didn’t even pet her, like most people do when they walk by an animal in front of a store. We still did not do anything. But the homeless man, who I thought did not buy himself anything to eat, went back into the store. And what he did brought tears to me and my wife. He had gone into the store and with what money he may have had, bought a can of dog food and fed that dog.
    This story plays a great part in our lives. You see, that was Mother’s Day weekend. And a lot of people forget that some animals are parents too.
    It took a homeless man, to show me what I should have done. He make me a better man that day.

A. were puzzled                         B. were greatly moved
C. regretted they hadn’t done anything     D. were indifferent

26. If the homeless man hadn’t given the dog food to eat, she and her babies would ____.
A. not survive    B. have to attack people   C. not have to die  D. lose their homes

    The kids in this village wear dirty, ragged clothes. They sleep beside cows and sheep in huts made of sticks and mud. They have no school. Yet they all can chant the English alphabet, and some can make words.

    The key to their success: 20 tablet computers(平板电脑) dropped off in their Ethiopian village in February by a U.S. group called One Laptop Per Child.

    The goal is to find out whether kids using today’s new technology can teach themselves to read in places where no schools or teachers exist. The Massachusetts Institute of Technology researchers analyzing the project data say they’re already amazed. “What I think has already happened is that the kids have already learned more than they would have in one year of kindergarten,” said Matt Keller, who runs the Ethiopia program.

    The fastest learner—and the first to turn on one of the tablets—is 8-year-old Kelbesa Negusse. The device’s camera was disabled to save memory, yet within weeks Kelbesa had figured out its workings and made the camera work. He called himself a lion, a marker of accomplishment in Ethiopia.

    With his tablet, Kelbasa rearranged the letters HSROE into one of the many English animal names he knows. Then he spelled words on his own. “Seven months ago he didn’t know any English. That’s unbelievable,” said Keller.

    The project aims to get kids to a stage called “deep reading,” where they can read to learn. It won’t be in Amharic, Ethiopia’s first language, but in English, which is widely seen as the ticket to higher paying jobs.

7. How does the Ethiopia program benefit the kids in the village?

AIt trains teachers for them.           

BIt contributes to their self-study.

CIt helps raise their living standards.    

DIt provides funds for building schools.

8. What can we infer from Keller’s words in Paragraph 3?

AThey need more time to analyze data.

BMore children are needed for the research.

CHe is confident about the future of the project.

DThe research should be carried out in kindergartens.

9. It amazed Keller that with the tablet Kelbesa could _______.

Alearn English words quickly.          

Bdraw pictures of animals.

Cwrite letters to researchers.            

Dmake phone calls to his friends.

10. What is the aim of the project?

ATo offer Ethiopians higher paying jobs.

BTo make Amharic widely used in the world.

CTo help Ethiopian kids read to learn in English.

DTo assist Ethiopians in learning their first language.

As we all know, sleep is very important and necessary. I would love everyone to form the habits below to have better sleep without needing the alarm wake­up call.

__21__ If you eat much food an hour before you go to bed, your body will hate you. Your body needs time to digest (消化) while you are still awake.

__22__Something that makes me very angry is when I hear on TV that people just need 30­minute exercise a week. That's funny. Every person should be getting 30­minute exercise daily along with a healthy diet. When you do exercise, you use energy that your body has to recover from. __23__ The harder you push your body, the faster it falls to sleep and the better it sleeps.

Turn the TV off. There are a few shows I watch still, but they will never get in my way of (妨碍) sleep. The bedroom is only for sleeping and a place of rest. __24__

__25__ A question to ask yourself: If I didn't have an alarm, what time would I get up? If that time is the time you need to get up, you should probably throw away the alarm. If the time you actually get up is much later than the time you do get up, make great changes to your way of life and the time you go to sleep. No one should need an alarm.

ATry to get up as early as you can.

BThrow away the alarm.

CEat right and no meals within 4 hours of rest.

DSleep is one of the most important things in our lives.

ETake the TV out of your bedroom.

FExercise for at least 30 minutes every day. 

GYour body recovers when you are sleeping.

The world is not always ________ we wish it to be.

A. that  B. which  C. what  D. where

Do you want to live forever? By the year 2050,you might actually get your wish-if you are willing to leave your biological body and live in silicon circuits (半导体电路). But long before then, perhaps as early as 2020,some measures will begin offering a semblance of immortality (虚的永生).
   Researchers are confident that the technology will soon be able to track every waking moment of your life? Whatever you see and hear, all that you say and write, can be recorded, analyzed and added to your  personal chronicles (
履历). By the year 2030, it may be possible to catch your nervous systems through electrical activities, which would also keep your thoughts and emotions.
    Researchers at the laboratories of British Telecommunications have given the name of this idea as Soul Catcher. Small electronic equipment will make preparation for Soul Catcher. It would use a wearable
supercomputer, perhaps in a wristwatch, with wireless links to microseosors under your scalp (
头皮) and in the nerves that carry all five sensory signals. So wearing a video camera would no longer be required.
    At first, the Soul Catcher's companion system-the Soul Reader-might have trouble copying your thoughts in complete details. Even in 2030, we may still be struggling to understand how the brain is working inside, so reading your thoughts and understanding your emotions might not be possible. But these signals could be kept for the day when they can be transferred to silicon circuits to revitalize minds everlasting entities (
永生实体). Researchers can only wonder what it will be like to wake up one day and find yourself alive inside a machine.
    For people who choose not to live in silicon, semblance of immortal it would not be as useless as they thought. People would know their lives would not be forgotten, but would be kept a record of the human
 race forever. And future generations would have a much fuller understanding of the past. History would not be controlled by just the rich and powerful, Hollywood stars, and a few thinkers in the upper society.
38.The main idea of this passage is that_____.
A. human beings long for living forever
B. there are many difficulties in making the Soul Catcher
C. people can live forever as technology develops
D. the invention of Soul Catcher has great importance
39. According to this passage, a Soul Catcher will be______ .
A. a new machine on which research measures have already been made
B. a new invention in order to catch and keep human's thoughts
C. made by British scientists to offer something that looks like living forever
D. made of silicon circuits which can catch people's nervous activity
40.We can infer from the passage that semblance of immortality is______.
 
A. to be a reality sooner or later
 
B. far from certain
C. just an idea that couldn't be realized at all
 
D. a fading hope
41.The meaning of the underlined word revitalize, in the fourth paragraph is close to___.
A. make dead
     B. make famous      C. make known      D. make active

A trip to the theater museum or art gallery could help you live longer And the more often you get that culture the better the results are a new study suggests

    Researchers from University College LondonUCL did the research on more than 6000 adults in England age 50 years and older How often an individual engaged in art activities was measured at the start of the study in 2004 to 2005 Participants were then followed up for an average of 12 years during which time deaths were recorded using data from the UK's National Health Service NHS). They found that people who engaged in the arts more frequency had a 31% lower risk of dying early when compared to those who didn't Even going to the theater or museum once or twice a year was linked with a 14% lower risk

    The study looked at a range of economic health and social factors to try and explain why there is a link between arts engagement and living longer Part of the reason the study said comes down to social and economic differences among those who go and don't go to museums exhibitions and art galleries Wealth they found explained about 9% of the association Cognitive(认知的)differences and mental health also played a role Things like free time and occupational status made no difference said Fancourt

    Engaging with the arts can act as a buffer against stress and build creativity that allows people to adapt to changing circumstances It also helps people access emotional support and information that helps people age more successfully "We also thought that a greater sense of purpose could play a role" she said"It can have wide ranging benefits and support healthier lives lived longer"

    A world health organization last year found that both receptive participation like visiting a museum and active participation like singing in a choir had health benefits An editorial that accompanied the paper said that everyone should have the chance to take part in cultural activities and said the study added weight to growing concerns about the decline in arts subjects in schools and universities

1What was the right step of the experiment     

A Following the participants for 12 years

B Recording the participants' death time

C Comparing the frequency of art activities

D Dividing the participants into two groups

2What has nothing to do with the relationship between "arts engagement and living longer"     

A Wealth

B Cognition

C Occupation

D Mental health

3What does the underlined word "buffer" in Paragraph 4 mean     

A Relief

B Barrier

C Defence

D Battle

Many of us know what it feels like to be an outsider in high school. Some give in to the pressure to fit in; others remain "on the bottom of the social food chain"  However, Alexandra Robbins, the author of the book The Geeks Shall Inherit The Earth believes what makes people unpopular in high school, mainly an unwillingness to obey, tends to translate into success as an adult.

Robbins has spent the past decade analyzing the behavior of high school students. She found the things that make a student different make them a target. But in adulthood and outside of the school setting, the things "that make you different make you interesting, fun, and often successful," she told the UK’s Daily Mail. She researched the qualities that people found most valuable in adults. The top qualities are: creativity, free-thinking, vision, authenticity, self-awareness, honesty, curiosity, love of learning, and courage. "Those are qualities that are far more likely to be found in school outsiders than in the popular kids," she said.

According to Robbins, when people are in with a popular crowd, they are more likely to hide aspects of their identity in order to fit into the group. As she put it to Yahoo. corn, "You are more likely to have goals of social dominance (强势) rather than forming actual true friendships. You are more likely to let other people pressure you into doing things. None of those things is admirable or useful as adults. " Meanwhile, in the eyes of Robbins, the outsiders are much more self-aware and much braver than the popular students. They are brave because they are sticking to being themselves in a challenging environment.

There are many celebrity examples of progress from unpopularity to later fame. Hollywood director Steven Spielberg was laughed at for being Jewish in high school. JK Rowling, author of hugely, popular Harry Potter. was teased in school as a glasses-wearing, child who lived mostly in books and daydreams. Robbins encourages students to participate in out-of-class activities. "They will automatically meet people with similar tastes," she told Daily Mail.

32. According to Robbins, what can make a student a target in high school?

A. Difference to others.                            B. Pressure to fit in.

 C. Unwillingness to obey.                  D. Behavior of high school students.

33. Which quality is NOT considered to be valuable in adults?

A. Being creative. B. Being authentic.  C. Being different.  D. Being curious.

34. Why do popular kids tend to be not as successful as outsiders?

 A. They may have goals of forming actual true friendships.

 B. They may hide aspects of their identity to fit in.

 C. They may force others into doing things.

 D. They may stick to being themselves in the society.

35. Which of the following statements is true?

 A. Young people who are outside are successful as adults.

 B. JK Rowling is one of celebrities of unpopularity.

 C. Unpopular students develop skills while the popular don't.D. Robbins encourages young people to be themselves.

The day that you enjoy all the 41___________(satisfy) of having all the housework done by a robot might still be a few decades off. But increasingly, engineers are saying 42______robots are going to make the leap from the factory floor to your family room.

Talking plants might sound like characters in a fairy tale. But recent scientific studies have shown that plants communicate with each other and with other living things in a surprising number of ways. To understand them, scientists say, we just have to learn their language. Farmers are especially interested in what plants have to say.

“Plants are able to communicate with all sorts of organisms (有机体). They can communicate with giant bacteria, with other plants and with insects. They do this chemically,” said Cahill, an Ecology Professor of the University of Alberta in Canada.
    Plant scientists are just beginning to understand this chemical “ language”. Cahill says studies have shown, for example, that plants can evaluate conditions in their immediate environment and take appropriate actions. Plants have an ability, for example, to signal pain or discomfort caused by anything from temperature extremes to an insect attack. Jack Schultz, a professor of chemical ecology at the University of Missouri, says when a plant senses that it’s being eaten, it cannot walk away from trouble; on the contrary, it will release a chemical vapor that alerts other plants nearby.
    “Their language is a chemical language, and it involves chemicals that move through the air that are easy to be changeable, and most of all are smells that we are familiar with,” Schultz explained.
    “All plants responded to the attack by changing their chemistry to defend themselves,” Schultz recalled.“But we were quite surprised to find that nearby plants also changed their chemistry to defend themselves, even though they were not part of the experiment.”
    Studies have also shown that plants under attack release pleasant chemicals. Those chemicals attract friendly insects that attack the pests eating the plant.

In the end, plants’ ability to communicate their needs---and our ability to understand them--- could help farmers reduce the use of poisonous chemicals, cut operating costs and limit damage to the environment.

                          Bring CPR training to schools

     King county in Washington state has the highest survival rates in the world for cardiac arrest(心率骤停)62percent. One of their secrets to success is the Student CPR Training Program, which  provides mandatory(强制的)CPR training for all students grades 6-12.   36     , so the more trained bystanders an area has, the higher the chances of survival for the victims.

     2. Get yourself trained.

                  38   , and round up all of the teachers and coaches you know to join in.

     3.         39    .

       If getting trained to be an instructor isn’t something you have the time for, have the students reach out to see if they can get volunteers to come in and train them.

     4. Show students just how easy it is.

              40      even if full training isn’t in the immediate future for you or your students. Every minute that goes by without CPR, a person’s chances of survival drop by 10 percent, so every little bit of action helps.

                                                  A. Bring in the experts.

                                                  B. Train as many students as possible

                                                  C. Bystanders are given some simple suggestions.

                                                  D. You can still take a moment to show them the basics.

                                                  E. When it comes to cardiac arrest, every minute counts.

                                                  F. If you’re not already certified, see if there’s a class offered locally.

                                                  G. Time and money play a big part in the hesitation of schools in offering training.

The first full choir rehearsal of the school year took place in the school hall. All the students joined together to sing. I watched as my elder sister and her grade came in and took their places next to us on the stage. Meanwhile, I could hear laughing. Some students were pointing at a girl standing next to my sister. I had never seen this girl before. A girl whispered in my ear,“Did you know she’s wearing diapers(纸尿裤)?
