Now it has been discovered that crows may understand analogies . To test this ability in animals, scientists do "relational matching-to-sample (RMTS)"tests. If a pair was AA, for example, then picking BB to match it would be correct. An international team led by Edward Wasserman in the US first trained two crows to match things by color1, shape, and number in what is called" identity matching-to-sample (IMTS)" , then moved onto RMTS. For the IMTS test, the birds were put in a cage with a plastic tray that had three cards and two cups in it. The card in the middle was the sample card. The cups on either side were covered with the other two cards. One was the same as the sample, while the other wasn' t. The cup with the card that matched the sample card contained two worms to eat. In the second part of the experiment, the birds were tested with relational matching pairs. A card with two same- sized circles, for example, meant they should pick the test card with two same-sized squares and not two different-sized circles. The birds did well in the more difficult test and picked the correct card more than three quarters of the time. Wasserman was surprised that crows were able to solve the problem without any training in RMTS. He said in a news release: "Honestly, if it was only by force that the crows showed this learning, then it would have been an impressive result. But this was spontaneous." So perhaps it' s time to stop saying " birdbrain" permanently. Question: Which of the following is TURE about the tests on the crows? - The birds did better in RMTS than in IMTS. - The birds were first made to do RMTS, then IMTS. - The birds picked almost all the correct cards in RMTS - In the IMTS test, the birds needed to identify the sample card to get rewards.
In the IMTS test, the birds needed to identify the sample card to get rewards.

I didn't know why, but once I was on my own bicycle, a kind of free feeling flooded through me. The faster I rode, the faster I wanted to go! Far ahead, I rode as if my life depended on it, head down, hands grasping the handbars. I meant to get to Jinghai Bar as fast as I could. . . Oh! My hands! Don't come any closer. . . Don't touch me! That poor doctor just couldn't get my gloves off. Each time he took a step towards me, I broke into painful shouting. Much later, I discovered that I had crashed heavily with another bicycle, and I hadn't spoken one word of sense for at least three hours! After some time, my mother arrived at the hospital, her face as white as a sheet, and gave me a hug , only then did the doctor begin to stitch my head wound, not only did he merrily cut off a long lock of my hair, but used no anaesthetic either! Later, I seemed to hear faraway voices saying that my right hand was broken. I almost burst into tears. How would I ever play the piano again? Question: On her way to Jinghai Bar, the writer felt _ . - nervous - comfortable - light-hearted - upset
light-hearted

Q: Read the following article and select the best answer. Article: Buying insurance is a way in which people can protect themselves against large losses. Protection against fire is one kind of insurance. Large numbers of people pay small sums of money to an insurance company. Although thousands of people have paid for fire insurance, only a few will lose their homes by fire. The insurance company will pay for these homes out of the small sums of money it has collected. The first modern fire insurance company was formed in London, England, in the 1760s. A great fire had just destroyed most of the city, and people wanted protection against further losses. The first company grew rapidly. Soon other companies were founded in other areas. Benjamin Franklin helped form the first fire insurance company in America in 1752, and then a new kind of insurance for farmers was suggested. The new insurance would provide protection against the loss of crops from storms. Later on another new insurance company was started in America. This company, which offered life insurance, collected small sums of money regularly from many different men. If a man died, his family was given a large sum of money. Over the years, insurance companies have offered new kinds of insurance protection. The new kinds of insurance cover losses from such accidents as car and plane crashes. Today, most people have some kind of insurance. Question: Who helped set up the first company in America? - Benjamin Franklin. - Businessmen. - The first insurance company in London. - Farmers.
A: Benjamin Franklin.

Read the following article and select the best answer. Article: A German study suggests that people who were too optimistic about their future actually faced greater risk of disability or death within 10 years than those pessimists who expected their future to be worse. The paper, published this March in Psychology and Aging, examined health and welfare surveys from roughly 40,000 Germans between ages 18 and 96. The surveys were conducted every year from 1993 to 2003. Survey respondents were asked to estimate their present and future life satisfaction on a scale of 0 to 10, among other questions. The researchers found that young adults (age 18 to 39) routinely overestimated their future life satisfaction, while middle-aged adults (age 40 to 64) more accurately predicted how they would feel in the future. Adults of 65 and older, however, were far more likely to underestimate their future life satisfaction. Not only did they feel more satisfied than they thought they would, the older pessimists seemed to suffer a lower ratio of disability and death for the study period. "We observed that being too optimistic in predicting a better future than actually observed was associated with a greater risk of disability and a greater risk of death within the following decade," wrote Frieder R. Lang, a professor at the University of Erlangen-Nuremberg. Lang and his colleagues believed that people who were pessimistic about their future may be more careful about their actions than people who expected a rosy future. "Seeing a dark future may encourage positive evaluations of the actual self and may contribute to taking improved precautions ," the authors wrote. Surprisingly, compared with those in poor health or who had low incomes, respondents who enjoyed good health or income were associated with expecting a greater decline. Also, the researchers said that higher income was related to a greater risk of disability. The authors of the study noted that there were limitations to their conclusions. Illness, medical treatment and personal loss could also have driven health... Question: According to the study, who made the most accurate prediction of their future life satisfaction? - Optimistic adults. - Middle-aged adults. - Adults in poor health. - Adults of lower income.
