Question

18．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 two thirds 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（昆蟲） has advantages（優(yōu)勢）．"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（心理上的） 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（鈣） deficiency，"says Durst．"But this is crazy when most Asians are lactose （乳糖） intolerant（不耐受）．"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．

A．there are fewer nutriments in insects
B．they can't overcome a mental barrier（精神障礙）
C．insects aren't as delicious as shrimps
D．insects don't have much meat themselves
26．It can be inferred from what Durst said thatD．
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 presen t
D．milk isn't suitable for most Asian people to increase calcium

Answer 1

分析 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．

解答 B.25-27 BDA
25．B　細節(jié)理解題．根據(jù)第四段Psychologically（心理上的） we have a problem with it．I don't know why，as we eat shrimps，which are very comparable．"可知，西方人不吃昆蟲的原因是有心理障礙．
26．D　推理判斷題．根據(jù)最后一段this is crazy when most Asians are lactose （乳糖） intolerant（不耐受）．"可知，亞洲人不適應(yīng)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．
27．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．

點評 做閱讀理解時要快速的瀏覽全文，把握文章主旨大意，帶著問題回到原文，尋找細節(jié)或概括相應(yīng)的答案，最后要理清作者寫作思路．
