　　答案：DABAC

　　Popping food into the microwave for a couple of minutes may seem utterly harmless, and Europe’s stock of these quick-cooking ovens emit as much carbon as nearly 7million cars, a new study has found, and the problem is growing. With costs falling and kitchen appliances becoming “status” users, owners are throwing many microwave after an average of eight years. This is pushing sales of new microwave which are expected to reach 135 million annually in the EU by the end of the decade.

　　A study by the University of Manchester worked out the emissions of carbon dioxide – the main greenhouse gas responsible for climate change – at every stage of microwaves, from manufacture to waste disposal. “It is electricity consumption by microwaves that has the biggest impact on the environment,” say the authors, who also calculate that the emissions from using 19 microwaves over a year are the same as those from a car. According to the same study, efforts to reduce consumption should focus on improving consumer awareness and behaviour to use appliances more efficiently. For example, electricity consumption by microwaves can be reduced by adjusting the time of cooking to the type of food.”

　　However, David Reay, professor of carbon management argues that, although microwaves use a great deal of enery, their emissions are minor compared to those from cars. In the UK alone and these emit way more than all the emissions from microwaves in the EU. Backing this up, recent data show that passenger cars in the UK emitted 69m tonnes of CO2 in 2015. This is 10 times the amount this new microwave oven study estimates for annual emissions for all the microwave ovens in the whole of the EU.” further, the energy used by microwaves is lower than any other form of cooking. Among common kitchen appliances used for cooking, microwaves are the most energy efficient, followed by a stove and finally a standard oven. Thus, rising microwave sales could be seen as a positive thing.

　　51. what is the finding of the new study?

　　A) Quick-cooking microwave ovens have become more popular.

　　B) The frequent use of microwaves may do harm to our health.

　　C) CO2 emissions constitute a major threat to the environment.

　　D) The use of microwaves emits more CO2 than people think.

　　【答案】D

　　【关键词】finding, the new study

　　【定位】第一段Popping food into the microwave for a couple of minutes may seem utterly harmless, and Europe’s stock of these quick-cooking ovens emit as much carbon as nearly 7million cars, a new study has found.

　　【同义替换】将食物放入微波炉几分钟似乎完全无害，而欧洲现有的这种快速烹饪烤箱所排放的碳相当于近700万辆汽车的碳量。从harmless排除了B选项。A和C在文中没有提到。D选项的排放二氧化碳和原文可以匹配。

　　52. Why are the sales of microwaves expected to use?

　　A) They are becoming more affordable.

　　B) They have a shorter life cycle than other appliances.

　　C) They are getting much easier to operate

　　D) They take less time to cook than other appliances.

　　【答案】A

　　【关键词】Why, sales of microwaves

　　【定位】第一段With costs falling and kitchen appliances becoming “status” users, owners are throwing many microwave after an average of eight years. This is pushing sales of new microwave which are expected to reach 135 million annually in the EU by the end of the decade.从this is pushing sales of new microwave …推断出答案是this，代词，也就是上文指代的内容。题目问的是why，找with，随着…。

　　【同义替换】costs falling，成本下降，是affordable(价格低廉的)的同义替换

　　53. What recommendation does the study by the University of Manchester make?

　　A) cooking food of different varieties

　　B) improving microwave user’ habits.

　　C) eating less to cut energy

　　D) using microwave ovens.

　　【答案】B

　　【关键词】recommendation, study, University of Manchester

　　【定位】第二段A study by the University of Manchester , 出现了University of Manchester 。往后面找建议。According to the same study, efforts to reduce consumption should focus on improving consumer awareness and behaviour to use appliances more efficiently.

　　【同义替换】improving consumer awareness and behaviour和文章的improving microwave user’ habits.可以匹配

　　54. What does Professor David Reay try to argue?

　　A) There are far more emissions from cars than from microwaves.

　　B) People should be persuaded into using passenger cars less often.

　　C) The UK produces less CO2 than many other countries in the EU.

　　D) More data are needed to show whether microwaves are harmful.

　　【答案】A

　　【关键词】David Reay, argue

　　【定位】第三段However, David Reay, professor of carbon management argues that, although microwaves use a great deal of energy, their emissions are minor compared to those from cars.尽管微波能消耗大量的能量，但与汽车所产生的能量相比，它的排放是微不足道的。

　　【同义替换】选项A汽车排放量比微波炉大，和文章的微波炉排放微不足道可以匹配。

　　55. What does Professor David Reay think of the use of microwaves?

　　A) It will become less popular in the coming decades.

　　B) It makes everyday cooking much more convenient,

　　C) It plays a positive role in environment protection.

　　D) it consumes more power than conventional cooking.

　　【答案】C

　　【关键词】David Reay, the use of microwaves

　　【定位】最后一段是David Reay的观点。Among common kitchen appliances used for cooking, microwaves are the most energy efficient, followed by a stove and finally a standard oven. Thus, rising microwave sales could be seen as a positive thing.

　　【同义替换】微波炉是最节能的;销量的上升是一件好事。和选项C的positive role in environment protection 可以匹配。
