    【题目】________ its suicide rate double in less than a decade, the country will also set up more counseling centers and try to increase awareness of the risks of depression.

    A. Having seen B. Seeing

    C. To see D. Seen

    【答案】A

    【解析】考查非谓语动词。句意：这个国家的自杀率在过去不足十年的时间里翻了一番。对此，这个国家也将增加心理咨询中心的数量，并设法提高对抑郁症风险的认识。分析句子可知，后一句已经有谓语动词set up，而且之间用逗号连接，没有连词，故判断此处用非谓语动词；“见证”发生在“建立”之前要用完成时，“国家”和“见证”是主动关系，要用v-ing形式。故选A。

    【题目】根据短文理解，选择正确答案。
    Four people in England back in 1953, stared at Photo 51,It wasn't much—a picture showing a black X. But three of these people won the Nobel Prize for figuring out what the photo really showed –the shape of DNA The discovery brought fame and fortune to scientists James Watson, Francis Crick, and Maurice Wilkins. The fourth, the one who actually made the picture, was left out.
    Her name was Rosalind Franklin.” She should have been up there,” says historian（历史学家） Mary Bowden.” If her photos hadn't been there, the others couldn't have come up with the structure.” One reason Franklin was missing was that she had died of cancer four years before the Nobel decision. But now scholars（学者）doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitors
    At Cambridge University in the 1950s, Watson and Click tried to make models by cutting up shapes of DNA's parts and then putting them together. In the meantime, at King's College in London, Franklin and Wilkins shone X-rays at the molecule(分子). The rays produced patterns reflection the shape.
    But Wilkins and Franklin's relationship was a lot rockier than the celebrated teamwork of Watson and Crick, Wilkins thought Franklin was hired to be his assistant .But the college actually employed her to take over the DNA project.
    What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out. And she was not shy about saying so. That angered Watson, who attacked her in return, “Mere inspection suggested that she would not easily bend. Clearly she had to to go or be put in her place.”
    As Franklin's competitors, Wilkins, Watson and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina Abir-Am. In 1962 at the Nobel Prize awarding ceremony, Wilkins thanked 13 colleagues by name before he mentioned Franklin, Watson wrote his book laughing at her. Crick wrote in 1974 that “Franklin was only two steps away from the solution.”
    No, Franklin was the solution. “She contributed more than any other player to solving the structure of DNA . She must be considered a co-discoverer,” Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the “Dark Lady of DNA”, Franklin is finally coming into the light.
    （1）What is the text mainly about?
    A.The disagreements among DNA researchers.
    B.The unfair treatment of Franklin.
    C.The process of discovering DN
    D.The race between two teams of scientists.
    （2）Watson was angry with Franklin because she .
    A.took the lead in the competition
    B.kept her results from him
    C.proved some of his findings wrong
    D.shared her data with other scientists
    （3）Why is Franklin described as “Dark Lady of DNA”?
    A.She developed pictures in dark labs.
    B.She discovered the black X-the shape of DN
    C.Her name was forgotten after her death.
    D.Her contribution was unknown to the public.
    （4）What is the writer's attitude toward Wilkins, Watson and Crick?
    A.Disapproving.
    B.Respectful.
    C. Admiring.
    D.Doubtful.

    【题目】根据短文理解，选择正确答案。
    People can be addicted to(沉溺于) different things — e.g. alcohol, drug, certain foods, or even television. People who have such an addiction are compulsive(强迫的):They have a very powerful psychological（心理上的）need that they feel they must satisfy. According to psychologists, many people are compulsive spenders. They feel that they must spend money. This compulsion, like most others, is impossible to explain reasonably. For compulsive spenders who buy on credit(以赊欠方式), charge accounts are even more exciting than money. In other words, compulsive spenders feel that with credit, they can do anything. Their pleasure in spending large amounts is actually greater than the pleasure that they get from the things they buy.
    There is even a special psychology of bargain hunting. To save money, of course, most people look for sales, low prices, and discounts. Compulsive bargain hunters, however, often buy things that they don't need just because they are cheap. They want to believe that they are helping their budgets(预算), but they are really playing an exciting game. When they can buy something for less than other people, they feel that they are winning. Most people, experts claim, have two reasons for their behavior: a good reason for the things that they do and the real reason.
    It is not only scientists, of course, who understand the psychology of spending habits, but also business people. Stores, companies, and advertisers use psychology to increase business. They consider people's needs for love, power, or influence, their basic values, their beliefs and opinions, and so on in their advertising and sales methods. Psychologists often use a method called “behavior therapy(疗法)” to help individuals solve their personality problems. In the same way, they can help people who feel that they have problems with money.
    （1）According to the psychologists, a compulsive spender is one who spends large amounts of money___.
    A.and takes great pleasure from what he or she buys
    B.in order to satisfy his or her basic needs in life
    C.just to meet his or her strong psychological need
    D.and feels he or she is cheated
    （2）Which of the following statements is TRUE according to the text?
    A.People spend money for exactly the same reason that they need to buy things.
    B.Business people and advertisers can use the psychology of people's spending habits to increase sales.
    C.Business people understand the psychology of compulsive buying better than scientists do.
    D.Compulsive bargain hunters do not have problems with money.
    （3）What is the text mainly about?
    A.The psychology of money-spending habits.
    B.The habits of compulsive spenders.
    C.A special psychology of bargain hunting.
    D.The use of the psychology of spending habits in business.
    （4）From the text we may safely conclude that compulsive spenders or compulsive bargain hunters _____.
    A.are really unreasonable
    B.need special treatment
    C.are really beyond drugs
    D.can never get any help to solve their problems with money
