2019-2020年高考英语一轮总复习 课时作业25 First aid 新人教版.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 worlds 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 dont. Psychologically we have a problem with it. I dont know why, as we eat shrimps, which are very parable.”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 overe 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.1According to Van Huis, westerners dont eat insects because _.Athere are fewer nutriments in insectsBthey cant overe a mental barrierCinsects arent as delicious as shrimpsDinsects dont have much meat themselves2The underlined part in the passage may mean _.Ainsects that can be eaten dont sell well in eastern countriesBthere are few eating insects in the markets of western countriesCit is difficult for westerners to accept the idea of eating insectsDselling eating insects in the west is hard to make a lot of money3It can be inferred from what Durst said that _.ALaos is where locusts and cricket are eaten mostBpeople in Laos are good at cooking eating insectsCeating insects in Laos is much more popular at presentDmilk isnt suitable for most Asian people to increase calcium4What might be the most suitable title for the passage?AInsects Are the Future of ProteinBInsects Are Rich in CalciumCInsects Are the Target of EatingDInsects Are the Alternative for Food答案与解析这是一篇说明文，说的是环保新理念。联合国粮农组织日前郑重宣布，用昆虫代替牛羊肉可满足全球人口增长带来的食物供给压力，还可减少温室气体排放。1B细节理解题。根据第四段倒数第二句可知，西方人不吃昆虫的原因是有心理障碍。2C句意理解题。从第四段西方人不吃昆虫，所以对他们来说接受吃昆虫的观点是困难的。3D推理判断题。根据最后一段倒数第三句可知，亚洲人不适应乳糖，所以利用牛奶来增加人们所需的钙的想法是不合适的。4A主旨大意题。本文主要功能介绍了随着地球上的人类越来越多，人们吃肉越来越多，会造成地球大气变暖，而假如人们吃昆虫的话，就会解决这一问题，以及吃昆虫的好处和一些研究等，所以A符合主题。.阅读填句A major source of teen stress is school exams, and test anxiety is not unmon.
