She loved them very much, but two girls would fight with each other from their earliest years. As they grew older, they became total strangers. They had no contact with each other when they were adults.This caused the mother great pain. Then, later, she had an idea. She decided to write a letter to them. In this letter, she told them how much she loved them, and how she wanted them to love each other in this way. She also gave them news of herself, and some guidance on how they might live happier lives.When the letter was ready, she wrote out one copy for each daughter, but these copies were special. Each copy contained only every second sentence of the original letter. The copy for one daughter had only the even(偶数的) sentences, and the other daughter‘s copy contained only the odd sentences. Neither copy made sense on its own. Neither contained the fullness of the mother‘s message.When the two daughters received their letters, they were puzzled. If they really wanted to know what the letters said, they would have to put the two letters together, and read them as one. That meant they must approach one another again in mutual(彼此的) love and respect.For a long time, the mother waited in vain. Both daughters tried to understand the half-letter, but they each blamed the other for not helping them. Each daughter thought she knew her mother better.Then one day, when the mother had almost given up hope, there was a knock at the door. There they stood, together. ―We‘ve come home,‖ they said at the same time. ―We‘ve finally put our letters together, and we‘ve come to say how much we love you, Mum.‖ Then she hugged them both, tears of joy streaming down her cheeks, and welcomed them back home.56. When the two daughters were young, they____.A. had no contact with each otherB. disliked each otherC. showed deep love for each otherD. did not love their mother57. Why did the mother give her daughters incomplete letters?A. She wanted to tell them her good news and bad news.B. She hoped they would ask her for more information.C. She hoped they would approach each other and make up.D. She thought she could change their attitude towards her.58. What did the two daughters do soon after they received their letters?A. They blamed each other again as usual.B. They made peace with each other quickly.C. They realized the mistakes they had made.D. They apologized to their mother.59. It can be inferred from the passage that _____.A. love can neither be bought nor soldB. faults are thick when love is thinC. without respect, love can‘t go farD. love can help enemies become friends60. What is the best title for this passage?A. An Unusual LetterB. A Mother‘s Endless LoveC. Special DaughtersD.

The advertisement is probably intended for ________.A. full-time college studentsB. working businessmenC. studying teenagersD. retired managersCThere is some unwelcome news for students preparing for exams and officers putting in long hours-----you don‘t need the break as much as you may think that makes you feel less tired.Scientists have long assumed that willpower (意志力) is a limited resource, which is why you feel the need to have a rest, have a snack and come back to a task when you're feeling better. They argued that the only way to restore willpower was by rest, food or entertainment.But psychologists have challenged this theory, saying weak willpower is all in your head. They found that people‘s beliefs in willpower determine how long and how well they'll be able to work on a tough mental exercise. ―If you think of willpower as something that‘s limited, you're more likely to be tired when you perform a difficult task," said Prof. Veronika Job. ―But if you think of willpower as something that is not easily used up, you can go on and on.‖.The researchers designed four experiments to test students'-beliefs in willpower. After a tiring task, those, who believed or were led to believe that willpower is a limited resource, performed worse on standard concentration tests than those who thought of willpower as something they had more control over. They also found that leading up to final exam week, students who believed the limited resource theory ate junk food 24 percent more often than those who believed they had more control in resisting temptation (诱惑).Mr. Job said. ―The theory that willpower is a limited resource is interesting, but it has had unintended consequences. Students who may already have trouble studying are being told that their power of concentration is limited, and they need to take frequent breaks. But a belief in willpower as a non-limited resource makes people stronger in their ability to work through challenges.‖The findings could help people who are bat tling temptation. Willpower isn‘t driven by a biologically based process as much as we used to think. The belief in it is what influences your behavior.66. The theory that willpower is limited supports that _________.A. people must eat snacks when they feel tiredB. people do need a break to restore their willpowerC. there‘s no way to strengthen people‘s willpowerD. weak willpower doesn‘t affect people‘s life much67. What have the scientists long believed regarding willpower?A. It is in the charge of people.B. It is a limited resource.C. There is no way to restore willpower.D. It doesn‘t easily run out.68. Which of the following best helps the students to prepare better for their exams?A. Push themselves even if they want to take a break.B. Don‘t eat fast food while studying.C. Remind themselves willpower is not limited.D. Stay in a comfortable and quiet place.69. The following groups can benefit from the findings except _______.A. patients following strict dietsB. children liking to watch TVC. smokers trying to give up smokingD. employees facing a new but well-paid task70. What‘s the best title for the passage?A. A new theory about willpowerB. How to build strong willpowerC. The great influence of willpowerD. Willpower doesn‘t la st longPart IV Writing (45 marks)Section A (10 marks)Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage.Write NO MORE THAN THREE WORDS for each answer.Do you know ―credit cards‖? They are very popular today. People use credit card to go shopping on the Internet, check into a hotel, rent a car, or dine out. People can buy now and pay later. A credit card may have a number of costs. First, there is the interest charge on purchase, known as the annual percentage rate. Second, Cardholders may have to pay cash advance fees if they withdraw money from credit cards.Compared to checks, a credit card allows small short – term loans to be quickly made to a customer who need not calculate a balance remaining before every transaction(交易、业务). Additionally there is no need for a customer to carry any cash for most purposes. Credit cards also offer consumers an easy way to track expenses.Credit cards are very convenient to use. But people who use credit cards irresponsibly can soon find themselves heavily in debt. Cardholders borrow money from a bank each time they charge something. They avoid interest charges if they pay their bill in full each month. But if they only make the minimum payment, it may take years to pay off a debt. Interest is continually charged on the unpaid balance.And that is not they only danger. Information security is a major issue these days. Recently there have been several incidents in which many people had financial information either lost or stolen. The cardholder suffered great losses. Now, major banks in China get more cautions inissuing caused by the card overdrafts(透支).Measures can be taken to avoid the problems. A lost or stolen card can be canceled in time, which will greatly limit the fraud. European banks require a cardholder‘s security code he entered for purchases with the card. In July, 2009, The China Banking Regulatory Commission forbade the issuing of credit cards to under 18–year–old age group.Section B (10 marks)Directions: Read the following passage. Answer the questions according to the information given in the passage.I‘m Bob. My first full-time job after high school was selling vacation packages via telephone for a well-known company. One day, the dialer （接线员）connected me to a man who answered the phone and sounded a bit out of breath. I started with my normal tone, and expecting to hear the normal response, ―I don‘t want any‖, and be hung up on.Instead he spoke in a weak voice and began to tell me how he wished he could take a vacation like the one I was offering, but he couldn‘t because he was dying of emphysema. He explained how he was on oxygen, and it took almost all his energy just to get to the phone to answer the call. I apologized to him for that. He asked me if I smoked and then begged me to stop. He told me smoking is what was killing him. He told me to spend every day with my loved ones, and tell them all the time how much I love them. At this point, I was in tears, and couldn‘t control myself, and he could tell. We ended the call, and I put my phone on hold to prevent another call from coming in so I could collect myself.After a few moments, I decided to write down his name and address, and just send him a card telling him that I appreciated his advice and that I would pray for him and his family. Shortly after, I received a nice letter back from Frank, along with a picture of him and his wife. We continued to write back and forth over the next few months, and became very fond of each other. He was old enough to be my grandfather, and in many ways, I felt as if he was.About a year later I received a letter from his wife. When I read it, my eyes were filled with tears. She told me how Frank‘s battle with the disease had finally come to an end, and he passed away shortly before Christmas. She wanted to thank me for the letters, and then explained how Frank touched many lives over the years. At his funeral, they read the first letter I had written to Frank to show how he affected a 19-year-old he had never even met.81. What would the customer normally do when the phone was connected?
