【正文】 The word it (in 2nd paragraph) probably refers to ______. A.They sleep upside down.C.Ways in which bats move differently from birds.（2）Which of the following is a false assumption about bats that was recently corrected? A.Why scientists have difficulty observing bats.C. these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly lives on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.（1）Which of the following is the topic of the passage? A. In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢體). This makes coordinating (協(xié)調(diào)) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or pletely reverse it, something a bird cannot easily do.5．犇犇Choose the one that fits best according to the information given in the passage you have just read. 故選A?？芍xD。 （3）考查細(xì)節(jié)理解。s protective system to lightadjusting glasses.

As a result, leaf growth on the plants scientists used in the study increased. Leaf growth in two plants increased by 20 percent, while leaf growth on a third plant increased by 14 percent. Scientists conducted the study on tobacco plants. But they think the genetic changes will produce the same results in corn and rice. （1）What will happen to the plants when scientists change plants39。s protective system to lightadjusting glasses. When a person wears the glasses outside during the day, the lenses（鏡片）darken and lighten depending on how sunny it is. Plants do the same thing, he said. But in plants the adjustment can take anywhere from 10 minutes to an hour. This makes it hard for plants to get the right amount of sunlight needed to create food. s protective system. Normally, this system is activated when a plant gets too much sunlight, said scientist Krishna Niyogi, coauthor of the study. When the plant senses the light, it gets rid of extra energy and creates more leaves. When the plant is in shade, the protective system is turned off, but the process is slow. s genes, the scientists were able to increase the amount of leaf growth on plants between 14 and 20 percent. s genes in order to make it use sunlight more quickly. Someday, the results could increase the amount of food produced around the world.

A.To prove sharing food increases petition.C.A meal taken in a family atmosphere.（2）For what purpose did the researchers carry out the present experiments? A.A meal consumed by oneself.B.A meal taken at home. The researchers measured cooperation by noting the number of rounds it took to reach an agreement, and found that those who shared food resolved the strike significantly faster（in 8. 7rounds）than those who did not（ rounds）. A similar experiment was conducted with 104participants and Goldfish crackers（餅干）, this time negotiating an airline39。 For the first test they recruited 100 pairs of participants from a local cafe, none of whom knew each other. The participants were seated at a table and fed tortilla chips with salsa. Half the pairs were given their own basket of 20 grams of chips and a bowl of 25 grams of salsa, and half were given 40 grams of chips and 50 grams of salsa to share. As a cover for the experiment, all participants were told this snack was to be consumed before the game began. Having conducted previous research in 2017 revealing that eating similar foods led to people feeling emotionally closer to one another, Dr Woolley and Dr Fishbach wondered whether the way in which food was served al
