高二英语下学期下册试题

   How do native speakers truly feel when speaking with non-native English speakers? It seems that   81   (break) English annoys them. However, they keep being really nice when speaking with non-native speakers. I wonder how they really feel when doing so.

   I think it would depend   82   the native English speakers. Some people are just   83   (easy) annoyed.

   Personally, I study Spanish. When I hear someone   84   (attempt) English, I am patient with them because I know   85   difficult it is to talk in a non-native tongue. I also know    86   is very difficult to learn English, and that increases my respect for their efforts. I’m a patient person by nature.

   The situation matters too. If I were waiting tables on   87   super crowded day and really   88   (need) to do about a dozen different things, I might become upset at having to wait for someone to struggle while ordering his meal.

   There also exists the   89   (possible) that what is considered as annoyance is not truly annoyance. I might frown (皱眉) while listening to a non-native speaker,   90   that wouldn’t mean I’m annoyed. I am just concentrating and listening hard to understand him.

Scientists claim to have developed a revolutionary new giant 3D concrete printer that can build a 2,500-square-foot house in just 24 hours.

The 3D printer, developed by Professor Behrokh Khoshnevis from the University of Southern California, could be used to build a whole house, layer by layer, in a single day.

"It is basically scaling up 3D printing to the scale of building," said Khoshnevis.

The giant robot replaces construction workers with a nozzle (喷嘴), which can quickly build a home based on a computer pattern, MSN News reported.

Contour Crafting, as it is named, is a layered fabrication (构造) technology. Using this process, a single house or a colony of houses, each with possibly a different design, may be constructed in a single run, embedded (嵌入) in each house all the wires and pipes for electrical, plumbing and air-conditioning.

The potential applications of this technology are far-reaching including in emergency, low-income, and commercial housing.

"Our research also addresses the application of Contour Crafting in building habitats on other planets. Contour Crafting will most probably be one of the very few feasible approaches for building structures on other planets, such as the Moon and Mars, which are being targeted for human habitation before the end of the new century," researchers said on the project website.

The technology may potentially reduce energy use and emissions. And the main advantages of the Contour Crafting process over existing technologies are the superior surface finish that is realized and the greatly increased speed of construction.

8. Professor Khoshnevis has recently developed a 3D printer that can ________.

   A. build a 2500-square-foot house in a single day.

   B. construct a skyscraper, layer by layer.

   C. design a group of houses automatically.

   D. assist construction workers in their work.

9. The new 3D printer uses the following to build a house EXCEPT ________.

   A. a nozzle        B. a computer pattern      C. a robot       D. an air-conditioner

10. According to the text, the potential applications of Contour Crafting include building _______.

   A. emergency vehicles             B. low-income housing

   C. commercial centers             D. space stations on other planets

11. What advantages of this new technology is mentioned in the text?

   A. It creates more jobs.             B. It is less time-consuming.

   C. It saves the building cost.         D. It emits no carbon dioxide.

Imagine loving someone so much that you’d swim more than 5,000 miles to see him or her. Dindim manages to swim that far every year to   21   his friend John.

    This is   22  , not only because of the love between the two friends, but because Dindim is 23     a penguin.

    John found Dindim covered in oil, hardly   24   on a beach near his home. He picked him up, cleaned him off and brought him to his house where he   25   him and got him healthy again. John named him Dindim.

    After a week, he   26   the penguin back to the beach and tried to release him,    27   Dindim refused to leave John. They   28   together for the next eleven months. Then, Dindim disappeared.  29  , John thought he’d never see his friend again.

    But just a few months   30   , Dindim was back. He found John on the beach, and followed him home. Each year, he   31   for four months to live with other penguins. For the other eight months, he lives with John.

    John says that each time they meet again, Dindim seems   32   to see him. He says he loves the penguin as if he were his own   33  . He feels certain that Dindim loves him in the   34    way.

    Ecologist Carl Safina says that animals can and do love humans. He writes and speaks a lot about animals and their   35  . According to Carl, it’s obvious that animals feel love for humans. What’s less obvious is whether or not human love animals enough to   36   them. Hundreds of thousands of animals are   37   by the same oil that covered Dindim when John found him. Fifty percent of   38   has disappeared in the last 40 years because of humans   39   their habitats(栖息地). Scientists say we’re in a new mass extinction period. In the next two   40  , they predict that we’ll lose 75 percent of the remaining species on earth.

Building Trust in a Relationship Again

Trust is a learned behavior that we gain from past experiences. 36   . Trust is a risk. But you can’t be successful when there’s a lack of trust in a relationship that results from an action where the wrongdoer takes no responsibility to fix the mistake.

Unfortunately, we’ve all been victims of betrayal. Whether we’ve been stolen from, lied to, misled, or cheated on, there are different levels of losing trust. Sometimes people simply can’t trust anymore. 37  It’s understandable, but if you’re willing to build trust in a relationship again, we have some steps you can take to get you there.*%

38  Having confidence in yourself will help you make better choices because you can see what the best outcome would be for your well-being.

39   If you’ve been betrayed, you are the victim of your circumstance. But there’s a difference between being a victim and living with a “victim mentality”. At some point in all of our lives, we’ll have our trust tested or violated.

You didn’t lose “everything”. Once trust is lost, what is left? Instead of looking at the situation from this hopeless angle, look at everything you still have and be thankful for all of the good in your life. 40   Instead, it’s a healthy way to work through the experience to allow room for positive growth and forgiveness.

A. Learn to really trust yourself.

B. It is putting confidence in someone.

C. Stop regarding yourself as the victim.

D. Remember that you can expect the best in return.

E. They’ve been too badly hurt and they can’t bear to let it happen again.

F. This knowledge carries over in their attitude toward their future relationships.

G. Seeing the positive side of things doesn’t mean you’re ignoring what happened.

       Soon after I returned to my seat, I saw the Flight Captain coming, looking at the seat numbers   49   he walkedWhen he got to my row he stopped, smiled, held out his   50  , and said, "I want to   51   your hand." I stood and took his handWith a loud voice he said, "I was a soldier  52  , someone bought me a lunchIt was such an act of   53   that I never forgot." I was a little bit   54   when applause rang out from all of the passengersThese soldiers were giving their all for our countryI could only give them a couple of meals

       Later, when I walked to the front of the plane to stretch my legs, a man   55   another twenty-five dollars in my hand

       When we   56   , I gathered my belongings and started to leaveA man stopped me, put something in my pocket, and walked away   57   a wordAnother twenty-five dollars!

The 87th Academy Award(奥斯卡金像奖) nominations(提名) were announced on Jan 15, and The Grand Budapest Hotel stood out as a favorite with nine nominations, including Best Picture. Check out some other Best Picture nominees to see if you missed any of last year’s top Hollywood films.

The Imitation Game

This historical thriller is about British computer scientist, Alan Turing (Benedict Cumberbatch), the father of artificial intelligence. At the start of World War II, Turing was asked to join a select team of mathematical geniuses to decode the system the Nazis used to send military messages. Besides the actual breaking of the code, Cumberbatch’s portrayal(扮演)of Turing’s personality, a mixture of decency(正派)and shyness, is also a highlight of the movie.

Birdman

This dark comedy film is about how Riggan Thomson, a faded star once famous for his superhero roles, struggles to regain fame. American actor Michael Keaton,  63, who has a similar experience to Thomson’s, plays the leading role.

Selma

A stellar cast(主要演员) including talk show queen Oprah Winfrey may be one reason to see Selma. But that the film focuses on Martin Luther King Jr.’s struggle for civil rights(民权) also makes it worth viewing. Based on the 1965 Selma to Montgomery voting rights marches, the film is a chronicle(编年史) of King’s (David Oyelowo) campaign for political rights for African-American people.

The Theory of Everything

We know English theoretical physicist Stephen Hawking for his significant scientific discoveries, especially his black hole theories. This biographical film reveals the scientist’s (played by Eddie Redmayne) secret romantic relationship with Jane Hawking (Felicity Jones), whom he meets and falls in love with at Cambridge and who later becomes his first wife.

Boyhood

American Director Richard Linklater did an experiment in this film, using the same cast for 12 years to record a boy’s growth. In two and a half hours, we see Mason, a Texas boy from a divorced family, grow from 6-year-old boy to a freshman in college.

How to Be a Winner

Sir Steven Redgrave

Winner of 5 Olympic Gold Medals

“In 1997 I was found to have developed diabetes (糖尿病). Believing my career was over, I felt extremely low. Then one of the specialists said there was no reason why I should stop training and competing. That was the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn't finished yet. Nothing is to stand in my way.”

Karen Pickering

Swimming World Champion

“I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success —you can’t follow a career in any field without being well-organized. List what you believe you can achieve. Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”

Kirsten Best

Poet & Writer

“When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological(心理的) tool.”

This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for anyone with two left feet.

The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately record not only how far and fast they run but also how well. It means the user maximizes their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers that watch the movements of your feet. They look, feel and can be washed like normal clothes.

Sensors (传感器) record each movement and send it by an ankle transmitter (脚踝发射器) to a smart phone. Then a “virtual coach” application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet.

The socks should be useful to athletes and weekend joggers. “People think running is so easy and of course everybody can do it but not necessarily safely and well,” Dr Davide Vigano said. A recent study showed that between 60 and 80 percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such golf, or even to help to teach women to walk better in high heels.

Mr. Vigano said, “People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely.”

Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around £120, which will go on sale in March.

       A 15-year-old boy planned to put a ball covered with petrol into his mouth and set it on fire. He would film the dangerous action and put it on YouTube. And, lie hoped to become famous on the Internet. But things didn’t go the way he imagined. His clothing caught fire, and he was rushed to the hospital with serious bums on his body.

      YouTube hosts millions of videos of people attempting dangerous actions. Many of them are by kids and young adults. Some experts say that by hosting these videos, YouTube encourages young viewers to take deadly risks. Research by the Centers for Disease Control and Prevention shows that more than 180,000 Americans die from accidental injuries each year. That’s one person every three minutes. More than 14,000 of those killed are kids under the age of 19. Is YouTube to blame?

       People have always found it interesting to watch others try risky things. Audiences love these kinds of things. Some of the earliest Greek comedies had characters followed by wild animals and knocking into walls. Now, in the age of the Internet, anyone with a camera and a YouTube account can create this kind of “fun”. Many viewers, especially teenagers, are influenced by what they see and want to try it themselves. “YouTube has taken the playing in the neighborhood to a worldwide level,” says Clair Mellenthin, a researcher from the Centers.

       Supporters of YouTube argue that it isn’t YouTube’s responsibility to examine its content. “Parents should be the ones to make sure that kids are behaving safely,” they say. In fact, YouTube has a rule on content. For example, dangerous activities that have a risk of serious physical harm or death are not allowed. Staff of YouTube, carefully watch the website 24 hours a day, looking for videos that are against their rules. But is this enough?
