第三大题、阅读理解（单选题）---以选项内容为准
Can trees talk? Yes, but not in words. Scientists have reason to believe that trees do communicate (交际) with each other.Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars (毛虫) changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them . Then even more astonishing, the tree sent out a special smell —  a signal (信号) causing its neighbors to change the chemistry of their own leaves and make them less tasty.
Communication, of course, doesn't need to be in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar (花蜜) for honey. So why shouldn't trees have ways of sending message?

【 B】： have an unpleasant taste
【单选题】 The willow tree described in the passage protected itself by  （）.
【 C】： changing its leaf chemistry

【 A】： making special movement

【 C】： seems completely reasonable
第四大题、阅读理解（判断题）
By 2050, the world's population is projected to rise to 9 billion from just over 7 billion currently. Proponents of genetically modified foods say they are safe and can boost harvests even in bad conditions by protecting against pests, weeds and
drought. This, they argue, will be essential to meeting the needs of a booming population in decades to come and avoiding starvation.
However, Doug Gurian-Sherman, senior scientist for the food and environment program at the Union of Concerned Scientists, an advocacy group, said genetic engineering for insect resistance has provided only a modest increase in yields since the 1990s and drought-resistant strains have only modestly reduced losses from drought.
.......................
Andrea Roberto Sonnino, chief of research at the U.N. food agency, said total food production at present is enough to feed the entire global population. The problem is uneven distribution, leaving 870 million suffering from hunger. He said world food production will need to increase by 60 percent to meet the demands of 9 billion by 2050 . This must be achieved by increasing yields, he added, because there is little room to expand cultivated land used for agriculture.
Genetically modified foods, in some instances, can help if the individual product has been assessed as safe, he said. “It's an opportunity that we cannot just miss.”
【判断题】 Para.1 mentions that the risks of genetic engineering are not that horrible.【 B】： F
【判断题】 Para. 5 tells us that uneven distribution leads to the starvation of 870 million people in the world.
【 A】： T
【判断题】 Para.  1 mentions that advocates of genetically modified food argue that GM  food  can meet the demands of increasing population.（）
【 A】： T
【判断题】Para. 2 mentions that insect-resistant genetically modified food has only  showed a fairly  small increase in production.  （）
【 A】： T
【判断题】Para. 3 mentions that the current food production is enough to feed the whole global population.
【 B】： F
