Part A
Directions: Read the following three texts. Answer the questions on each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1.
To enjoy a longer life has been a dream for mankind since always. With the improvement of health care, nutrition and health knowledge, we began to make dramatic efforts to reduce the effects of the forces that had traditionally shortened human existence.
10 million to 17 million people aged 65 or older made up less than 1 percent of the world's population in 1900. Survival rates began to climb for infants, children and women of childbearing age, gradually lifting humanity's average life span. By 2000, 606 million were aged 60 or older, and they made up almost 10 percent of the world's population. According to the United Nations report World Population Prospects, by 2050 that group could swell to 1.9 billion and constitute one fifth of the world's projected population.
But it is not all about to live a longer life. And it would not be such a good idea to live your last years in illness and pain. In fact, it would turn into a torture. No, we want to live better, more youthful days while we're living longer. Diet, exercise and a lucky draw from the gene pool can take us only so far, however. That's where science comes in.
As medicine tries to find out the means to extend life, culture and its institutions will have to deal with the consequences of success. Age-entitlement programs, such as Social Security, were formed when younger workers far outnumbered retirees, who drew benefits for only a few years; what reforms will longer lives require？ When savings are used up by parents who may be retired for up to one third of their lives？ And, equally important, how will we make our extra years emotionally rewarding and rich？
Medicine will continue to advance, and, we expect, society and policymakers will have to learn to adapt to the challenges of longevity-both providing it and providing for it-that await us all.
Which one of the following is not mentioned in paragraph 1 as the motivation for people to try to live a longer life？

Task 1
Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 36 through 40. For each question or statement there are 4 choices marked A, B, C, and D. You should make the correct choice.
The purpose of any selection interview is to choose the right person for the job in question or to select someone who shows potential for more senior posts. Interviews may not be the ideal method of selecting staff. For one thing, you will not know whether you have selected wisely until long after the interview. The period you have to wait will depend on the job in question. The lower the level of the job is, the quicker you will discover how good you were with your selection. Be clear what you are trying to achieve by the interview and how you intend to do it.
Interviewing requires many skills which typically only develop with practice. Be careful that you are not being subjective in your judgments(判断); try to be objective wherever possible. An example may illustrate the point. If you interview a long-haired male applicant, you may be put off by the length of his hair; you may associate the long hair with untidiness, dirt or laziness.
This is a subjective judgment—another interviewer may not be affected by hair length in the same way.
Subjective misjudgment is sometimes called the "halo and horn" effect. We meet someone neatly dressed and well-spoken, and from this we assume that they are all things good; that they will be reliable, honest, hard working, etc. We are blinded by their halo. Conversely, on meeting a roughly-spoken, scruffy(褴褛的)individual we decide they will be unreliable, careless and lazy. We only see their horns. This problem needs to be overcome, since we could so easily overlook first-class candidates(候选人)for vital posts because we have not been objective.
Which of the following best summarizes the main idea of the essay？
A．In the library.B．In the bookstore.C．In a teacher's office.D．In a classroom.
