Habits, whether good or bad, are gradually formed. When a person does a certain thing again, he is driven by some unseen force to do the same thing repeatedly, then a habit is formed. Once a habit is formed, it is difficult, and sometimes impossible, to get rid of. It is therefore very important that we should pay great attention to the formation of habits. Children often form bad habits, some of which remain with them as long as they live. Older persons also form bad habits lasting as long as they live, and sometimes become ruined by them.

There are other habits which, when formed in early life, are of great help. Many successful men say that much of their success has something to do with certain habits in early life, such as early rising, honesty and so on.

Among the habits which children should not form are laziness, lying, stealing and so on. These are all easily formed habits. Unfortunately older persons often form habits which could have been avoided .

We should keep away from all these bad habits, and try to form such habits as will be good for ourselves and others.

1. ________ are formed little by little.

A. Good habits

B. Bad habits

C. Both good habits and bad habits

D. Either good habits or bad habits

2. The underlined word "them" in the first paragraph refers to ________.

A. bad habits      B. good habits

C. children        D. other persons. 

3. Why should we pay much attention to the formation of habits?      

A. Because habits are of great help to every one of us.

B. Because a man can never get rid of a habit.

C. Because it's hard and sometimes even impossible to throw away bad habits.

D. Because we are forced to do them again and again.

4. According to the passage, early rising ________.

A. has something to do with success

B. is an easily formed habit

C. is such a habit as should have been avoided

D. is such a habit as will be kept                                      

For years we have been told that encouraging a child’s self-respect is important to his or her success in life. But child experts are now learning that too much praise can lead to the opposite effect. Praise-aholic kids who expect it at every turn may become teens who seek the same kind of approval from their friends when asked if they want to go in the backseat of the car.

The implication (含义) of saying “You are the prettiest girl in class,” or talking about the goals she scored but not her overall effort, is that you love her only when she looks the best, scores the highest, achieves the most. And this carries over to the classroom.

Social psychologist Carol Dweck, PhD, tested the effects of overpraise on 400 fifth graders while she was at Columbia University. She found that kids praised for “trying hard” did better on tests and were more likely to take on difficult assignments than those praised for being “smart”.

“Praising attributes (品质) or abilities makes a false promise that success will come to you because you have that quality, and it devalues effort, so children are afraid to take on challenges,” says Dweck, now at Stanford University. “They figure they’d better quit while they’re ahead.”

29. The underlined words “Praise-aholic kids” refer to kids who are ______.

   A. tired of being praised             B. worthy of being praised

   C. very proud of being praised        D. extremely fond of being praised

30. The author quoted (引用) Dr. Dweck’s words in the last paragraph in order to make the article ________. 

A. better-known    B. better-organized    C. more persuasive   D. more interesting

31. We can infer from the passage that _____.

   A. praise for efforts should be more encouraged

   B. praise for results works better than praise for efforts

   C. praising a child’s achievements benefits his or her success in life

   D. praising a child’s abilities encourages him or her to take on challenges

About 2 months ago I realized how often my mother's caregiver(看护者)would do kind things for me.       36        She always does things which touch me so mush, like picking oranges and juicing them, making my bed for me when my muscles are so tight I can’t bend over easily, clearing the leaves and weeding the front yard... those kinds of things.

       37      But I decided to help her, since she is paid a set wage by the agency we went through, and has a large family to raise. I would put a dollar in a decorative box every time I see one of those kinds of things that she has done for me.

I have already changed out 20 single dollar bills for a $20 bill TWICE and have probably about $70 in there.        38       When the time comes (and it will, probably this year) when we can no longer afford a caregiver for my mother, I will have a box of money that will say thank you in a clear way.

       39        She is our own precious angel. And while I know she does these things out of kindness and love for us, it will be my chance to do something out of love and kindness for her. Because it is just a dollar every now and then, it is hardly missed. But in 6 months, or however long it is before the money runs out, it will have grown to quite a bundle of love.

I don’t want the day to come when she will no longer be with us. The reason is that I will miss her presence terribly.        40       

It’s a small gas station that has snacks, drinks, cigarettes, and candies. The young man behind the counter knows his  21  by name and what they normally want to buy. He treats children and adults with equal  22  .

He reads science fiction behind the counter when business is __23  .

One day, three people rushed in and grabbed food off the shelves as fast as they could, __24  not intending to pay for it. He hit the “panic button” , then went over the counter and  __25  the front door. It was obvious that they were homeless, and equally obvious that they weren't going __26  with their ill-gotten gains. They 27 the food and simply crowded together in panic-knowing the police were  28 the way.

Imagine what they must have felt like when they were told they didn't have to steal if they were that  29. "We have food in the back, expired (到期)but still 30 to eat. If you need food, you  31   have some." 

They were told to  32  what they had dropped and put it back, and then asked to straighten out the mess. They were doing just that  33  the police arrived. The officers were told the situation was under control and the police were no longer 34 .

This wasn't what they had _35 . They were being treated as human beings who could right the wrong they'd done. Shocked, they quickly followed orders to take turns and use the restroom to clean up. 

Soon three _36  people walked out with all the __37   their arms could hold. They were __38   that, if they needed to come back again, they were to ask and not just grab.

And then the young man went back to read until the next customer came in. He would be the __39  

person in the world to claim he was a hero. But he gave three people something they were in desperate need of-a _40  amount of self-respect and a little bit of hope.

Once a circle(wooden wheel) missed a wedge(楔子). The circle wanted to be whole, so it went around looking for its missing piece. It was incomplete and   35   could roll only very slowly. While rolling, it   36   the flowers along the way, chatted with worms and enjoyed the   37   .

One day the circle found a piece that fit perfectly. It was so   38  ! Now it could be   39   with nothing missing. It fixed the missing piece in itself and began to roll.   40   it was a perfect circle, it could roll very fast, too fast to   41   the flowers or talk to the worms. When it realized how   42   the world seemed when it rolled so quickly, it stopped,   43   its found piece by the side of the road and rolled slowly away.

The   44  of the story, I think, is that in some strange sense we are more whole when we are   45   something. The man who has everything is  46  a poor man. He will never know   47   it feels like to desire, to hope, to nourish（滋养） his soul with the dream of something   48  .

If we are brave enough to let go of our unrealistic dreams,   49   enough to go through a tragedy and survive, generous enough to   50   another’s happiness, and wise enough to know there is enough love to go around for us all, then we can achieve our dreams that   51   living creature will ever know.

When we accept that  52   is part of human being, and when we can continue rolling   53   life and appreciate it, we will have achieved a wholeness that others can only   54   to. That, I believe, is what God asks of us—not "Be perfect", not "Don't even make a mistake", but "Be whole".

                    Five Things to Do in a Traffic Jam

Tired of traffic jams? Here are some tips that can help you to calm down in a traffic jam.

Listen to a CD audio book
     It’s a good idea to keep several audio books in your car.   16     Listening to an

exciting story is more interesting than sitting silently and being bored.

Sing loudly
If you begin getting angry because of a long traffic jam, turn your CD player on or

 radio up.   17   Imagine you’re a wonderful singer and the audience is listening to you in

 admiration. Your stress will disappear.

 18    
You can use the radio and play entertaining games while waiting. For example you can

 guess the song or the singer or to see how quickly you can recognize a new song.

Have a snack
Keeping a tasty snack in the car is especially good for waiting in traffic jams. Choose

what you like most of all, so you will look forward to traffic jams to have a chance to eat the

delicious snack.   19   In that case, time is the last thing to worry about.

Argue with the radio talk show host
Find a station with a radio talk show.    20   If you disagree, you can show your

anger. Don’t be afraid to call their ideas stupid. Only make sure that the car windows are

closed so no one may hear you.

I lost my elderly mother a few weeks ago. Actually, my mother had fallen over during the night and had not been able to   36  again. She had woken up the neighbors by banging on the wall. The

  37   called an ambulance, which took her   38   to the hospital.

My mother has   39   thought that hospitals are frightening. She believes that doctors and hospitals give you   40   diseases. My father went to hospital a year ago, and after a few weeks, he   41  . The fact that he was also in the final   42   of lung cancer was certainly related, but by my mother’s logic, my father’s death was   43   with the hospital.

When a neighbor   44   me up and told me that my mother had been taken off in an ambulance, the first thing I did was similar, which was to ring Queen Elizabeth Hospital. The paramedics(护理人员) had told my neighbor that my mother would   45   be taken there,   46 

I was told that no one by that name had been   47  , so they gave me the numbers of two other West Midland hospital. They didn’t   48   they were holding my mother. I rang the   49   and asked them to find her, but the nice officer said he could only do that if she had been reported as a(n)

  50   person.

It took six calls to   51   my mother. She had been in Queen Elizabeth Hospital all along, but because their computer system hadn’t been updated overnight , there was no record of her   52  . My mother had spent more than a   53   in the hospital when it turned out there was nothing   54

with her. I managed to get her out within 10 days, but only by agreeing that in the future, she would live downstairs. In return, the hospital said they would   55   for a social worker to visit the house three or four times a day.

Luckily, my mother is safe. Thank all the people who have given their help to us .

    More than 2.25 billion cups of coffee are drunk throughout the world each day, and it’s likely that many taste bitter. Now, a new study suggests that coffee fans can make their drink sweeter by changing the color of their cups.

    Researchers from Oxford set out to prove whether the claim that coffee drunk from a white cup tastes biter was true. They used 36 volunteers and three different colored cups---blue, white and transparent glass--- to examine the claim.

    In one experiment, the white cup increased the intensity (浓度) of the coffee taste relative to the transparent cup. Then, in a second experiment, coffee drunk from the white cup was found to taste less sweet when compared to the other colored cups, while the blue cup made the coffee taste the sweetest.

    The scientists believe that the color brown may be associated with bitterness, and coffee in a white cup appears the brownest.

    “Our study clearly shows that the color of a cup does influence our sense of the coffee taste,” leading author Dr. George Doorn, wrote in an article for The Conversation. “The effect of the color of the cup on the taste of the coffee reported here suggests that cafe owners should carefully consider the color of their cups,” he said. “The potential effects may spell the difference between a one-time purchase and a return customer.”

    Actually, the idea that color can change the food and drink taste came out many years ago. A study published last year reported that red, strawberry-flavored cake served on a white plate was rated as 10 percent sweeter than the same food presented on a black plate.

28. The passage is mainly about _____.

   A. the popularity of sweet coffee.

   B. an experiment made in Oxford.

   C. the effect of cup color on coffee’s taste 

   D. useful tips on how to make coffee.

29. In which cup will coffee taste the sweetest?

   A. A white cup.            B. A blue cup. 

   C. A transparent cup       D. A brown cup

30. Café owners should consider their cups’ color in order to ______.

   A. reduce the daily expenses     B. show their taste in coffee

   C. appeal to more customers      D. make their café different.

31. We learn from the passage that_____.

   A. coffee in a white cup tastes sweeter than that in a transparent glass

   B. over 2 billion cups of sweet coffee are drunk worldwide each year.

   C. Dr. George Doorn wrote an article about making conversations.

   D. the idea that color could affect the taste of drink is not new

    My husband, my four-month-old daughter and I set out on a five-day driving journey from California to Washington. We had to stop frequently because our little child needed to stretch from the car seat.

    One of our stops, once we crossed the Oregon border, was at a Black Bear Diner. Walking towards the front door we noticed a gentleman standing at one side. He was clearly untidy, without shoes and wearing worn clothing. We passed right by him and opened the restaurant door. Then something told me to go back.

    Holding my daughter, I turned around and said to the gentleman, “Sir. Are you hungry?” He said, “Yes.” I then asked, “May we buy you something to eat?” He responded with, “Sure, I can order something myself.”

    My husband opened the door and the gentleman went straight to the counter. I told him to order whatever he wanted. The manager of the restaurant came over quite quickly and looked frightened. I spoke before he had an opportunity to. “This gentleman will have lunch with us today,” I said. “Please add his order to our bill.” The manager said with a frown(皱眉), “Okay.” We turned to our table and the gentleman said, loudly and quickly, “Thank You!” We were seated and upon completing our meal we were handed our bill. I asked my husband what the gentleman had ordered. One fresh orange juice, one coffee, one breakfast combination with a side of hash browns.

    When we left the restaurant I looked for the gentleman but didn’t see him, but that very small act just made my day. I hope in some small way we were able to add some joy to his life, even if only for a few minutes.

33．From the appearance of the gentleman, we can guess he was probably a(n) ________.

       A. waiter      B. actor         C. worker             D. beggar

34．The manager of the restaurant looked frightened because ________.

       A. the man was not friendly

       B. the man had stolen something from the restaurant

       C. he was afraid the man wouldn’t afford to pay the food

       D. he had fired the man before

35．From the passage, we can infer the man ________.

       A. felt ashamed and slipped away                   B. was thankful for their kind act

       C. was hungry and ate a lot of food          D. was too proud to accept their offer

36．The phrase “made my day” in the last paragraph probably means ________.

       A. made me very happy                             B. wasted my money

       C. made me feel sorry                              D. moved me deeply

Are you truly happy? Do you ever know what it means to be happy and what it takes to achieve happiness? __41__. The following are a few tips that I follow to create happiness in my life.

※ Make a plan for attaining goals that you believe will make you happy. Your moods will very likely increase if you are going after something you value.

※Surround yourself with happy people. It is easy to begin to think negatively when you are surrounded by people who think that way. __42__.

※When something goes wrong, try to figure out a solution instead of being absorbed in self pity. Truly happy people don’t allow setbacks to affect their mood because they know that with a little thought they can turn the circumstances back to their favor.

※__43__. These few minutes will give you the opportunity to focus on the positive things in your life and will lead you to continuous happiness.

※ __44__. Whether you treat yourself to lunch, take a long, relaxing bath or simply spend a few extra minutes on your appearance, you will be subconsciously (下意识地) putting yourself in a better mood.

※Finding the humor in situations can also lead to happiness. Find a way to make light of a situation that would otherwise make you happy.

Switching the lights off or wearing a blindfold(蒙眼布)while eating could be a fast way to lose weight, according to scientists. The simple trick works because it stops diners eating for pleasure rather than for calories. It also triggers (引发) a part of the brain that is worried that unseen food may go bad.

 An experiment by the University of Konstanz, in Germany, found that people who were blindfolded consumed nine percent fewer calories before they felt full, compared to those who could see. They also vastly overestimated（高估） how much they had eaten because they could not see how much was left on the plate. Blindfolded volunteers estimated they had eaten 88 percent more than they actually had.

Scientists believe that not seeing food on the table also allows the body to know when it is full in real time rather than remembering past experiences where it might have taken a full plate to feel full.

In the experiment, 50 people were blindfolded and 40 were allowed to see their food. All were told not to eat within two hours of the experiment. They were then given three 95g bowls of chocolate ice cream and invited to eat for 15 minutes. Their bowls were taken away and the remaining ice-cream weighed, while the participants were quizzed on how much they thought they had eaten.

On average the group who could see ate 116g while the blindfolded groups ate 105g. However, the blindfolded group believed they had eaten 197g while compared with 159g for the non-blind volunteers. They were also asked how pleasant the ice-cream tasted and the blindfolded group rated lower than those who could see.

“The experienced pleasure of eating was significantly lower in the blindfolded group. Not seeing the food might have decreased the appetite. Sight plays an important role in the eating experience and in the overall dining experience.”

Previous studies have shown that the visual influence of food plays a large part in the taste. While restaurants that allow diners to eat in the dark state that it triggers other senses, in fact eating in darkness is likely to taste far milder than usual.
