Unit 5 First aid using language Ⅰ.阅读理解Saving the planet one plateful at a time does not mean cutting back on meat, according to new research: the trick may be to switch our diet to insects.The raising of livestock such as cows, pigs and sheep occupies twothirds of the world's farmland and produces 20% of all the greenhouse gases driving global warming. As a result, the United Nations wants to reduce the amount of meat we eat and the search is on for alternatives.Professor Arnold van Huis says eating insects has advantages. “There is a meat crisis，” he said. “The world population will grow from six billion now to nine billion by 2050 and we know people are consuming more meat. Twenty years ago the average was 20kg, it is now 50kg, and will be 80kg in 20 years. If we continue like this we will need another Earth.” “Most of the world already eats insects，” he points out. “It is only in the western world that we don't. Psychologically we have a problem with it. I don't know why, as we eat shrimps, which are very comparable.”The advantages of this diet include insects' high levels of protein, vitamin and mineral content. Being coldblooded, insects change plant matter into protein extremely efficiently. In addition, the health risks are lower. He acknowledges that in_the_west_eating_insects_is_a_hard_sell，“It is very important how you prepare them, you have to do it very nicely, to overcome the yuk factor.”Durst helped set up an insect farming project FAO project in Laos. This involves transferring the skills of the 15,000 household locust farmers in Thailand across the border. “There were some supporters of a bigger dairy industry in Laos to improve a calcium deficiency, ”says Durst.“But this is crazy when most Asians are lactose (乳糖) intolerant.” Locusts and crickets are calciumrich and 90% of people in Laos have eaten insects at some point. Durst says the project will be to increase the eating of insects where this is already accepted but has been in decline due to western cultural influence.1．According to Van Huis, westerners don't eat insects because ________.A．there are fewer nutriments in insectsB．they can't overcome a mental barrierC．insects aren't as delicious as shrimpsD．insects don't have much meat themselves2．The underlined part in the passage may mean ________.A．insects that can be eaten don't sell well in eastern countriesB．there are few eating insects in the markets of western countriesC．it is difficult for westerners to accept the idea of eating insectsD．selling eating insects in the west is hard to make a lot of money3．It can be inferred from what Durst said that ________.A．Laos is where locusts and cricket are eaten mostB．people in Laos are good at cooking eating insectsC．eating insects in Laos is much more popular at presentD．milk isn't suitable for most Asian people to increase calcium4．What might be the most suitable title for the passage?A．Insects Are the Future of ProteinB．Insects Are Rich in CalciumC．Insects Are the Target of EatingD．Insects Are the Alternative for FoodⅡ.阅读填句A major source of teen stress is school exams, and test anxiety is not uncommon.
