2019-2020年高考英語一輪總復習 課時作業(yè)25 First aid 新人教版 Ⅰ.閱讀理解 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. 1．According to Van Huis, westerners dont eat insects because ________. A．there are fewer nutriments in insects B．they cant overe a mental barrier C．insects arent as delicious as shrimps D．insects dont have much meat themselves 2．The underlined part in the passage may mean ________. A．insects that can be eaten dont sell well in eastern countries B．there are few eating insects in the markets of western countries C．it is difficult for westerners to accept the idea of eating insects D．selling eating insects in the west is hard to make a lot of money 3．It can be inferred from what Durst said that ________. A．Laos is where locusts and cricket are eaten most B．people in Laos are good at cooking eating insects C．eating insects in Laos is much more popular at present D．milk isnt suitable for most Asian people to increase calcium 4．What might be the most suitable title for the passage? A．Insects Are the Future of Protein B．Insects Are Rich in Calcium C．Insects Are the Target of Eating D．Insects Are the Alternative for Food 答案與解析 這是一篇說明文，說的是環(huán)保新理念。聯(lián)合國糧農(nóng)組織日前鄭重宣布，用昆蟲代替牛羊肉可滿足全球人口增長帶來的食物供給壓力，還可減少溫室氣體排放。 1．B　細節(jié)理解題。根據(jù)第四段倒數(shù)第二句可知，西方人不吃昆蟲的原因是有心理障礙。 2．C　句意理解題。從第四段西方人不吃昆蟲，所以對他們來說接受吃昆蟲的觀點是困難的。 3．D　推理判斷題。根據(jù)最后一段倒數(shù)第三句可知，亞洲人不適應乳糖，所以利用牛奶來增加人們所需的鈣的想法是不合適的。 4．A　主旨大意題。本文主要功能介紹了隨著地球上的人類越來越多，人們吃肉越來越多，會造成地球大氣變暖，而假如人們吃昆蟲的話，就會解決這一問題，以及吃昆蟲的好處和一些研究等，所以A符合主題。 Ⅱ.閱讀填句 A major source of teen stress is school exams, and test anxiety is not unmon.
