Question

【题目】More than three billion people are at risk from indoor air pollution because of the heating or cooking fuels they use. Most live in Africa, India and China. They use wood, crop waste, animal waste or coal. These solid fuels may be the least costly fuels available. But they are also a major cause of health problems and death.

The Aprovecho Research Center has been designing cooking stoves for the developing world. People having less money use wood or biomass for cooking; the richer people use oil and gas. It's estimated that wood is running out more quickly than oil and gas.

The group has made stoves using mud, bricks, sheet metal, clay, ceramics and old oil drums. Most of the stoves look like large, deep cooking pots. They have an opening at the bottom for the fire and a place on top to put a pot.

In the late 1970s, Aprovecho produced a popular stove called the Lorena. The Lorena was good at reducing smoke and warming homes. But new tests years later found that it was not efficient. The used twice as much wood as an open fire, and took much longer to heat food. Since then, they have experimented with count-less other designs.

Their goal is to make an inexpensive stove—let's say five dollars— that makes little smoke, and it's safe for health and reduces global warming and deforestation(采伐森林).

Aprovecho has now partnered with a stove manufacturer in China. The company is making Aprovecho's first mass produced stoves. They are said to use 40% - 50% less wood than an open fire, and produce 50% -70% less smoke. A company called Stove-Tec is selling them through its Web site for less than ten dollars. Dean Still says that more than one hundred thousand have been sold so far.

【1】 The underlined word " biomass " ，in Paragraph 2 refers to __________

A. oil and gas B. wood

C. coal D. crop waste or animal waste

【2】 The following sentence is taken from the passage, it is probably placed at the end of __________.

A World Health Organization estimate that over 1,500,000 people a year die from breathing smoke from solid fuels.

A. Paragraph 1 B. Paragraph 2

C. Paragraph 3 D. Paragraph 4

【3】 Which information about the Lorena mentioned in Paragraph 4is WRONG?

A. It was a popular stove which began to produce in 1970.

B. It was able to be used to bring down smoke.

C. It was good at heating houses.

D. It turned to consume more fuel later.

【4】 Stoves the Aprovecho Research Center has been designing should have the following characteristics ：__________.

（1）enormous （2）costly （3）efficient (4)low-carbon (5) cleaner

A. 1. 2. 4 B. 3. 4. 5.

C. 2. 3. 5. D. 1. 3. 4.

【5】 You can probably read the passage in a magazine about __________

A climate change

B. financial crisis

C. an environmentally-friendly life

D. commercial advertisement

Answer 1

【答案】【1】 D

【2】 A

【3】 A

【4】 B

【5】 C

【解析】【1】 猜测词义题。根据 the richer people use oil and gas 可以排除A项。第一段中介绍发展中国家人们使用wood, crop waste, animal waste or coal, 而 biomass 所在的句子为 People having less money use wood or biomass for cooking, 故可排除 B项，煤炭也是需要花钱的，因此不怎么花钱的燃料除了木头就是 crop waste 和 animal waste.

【2】 推理判断题。根据第一段末尾句But they are also a major cause of health problems and death. 可知。

【3】细节理解题。可以运用排除法，根据In the late 1970s, Aprovecho produced a popular stove called the Lorena. 可知 A选项错误。

【4】推理判断题。根据第四段中The Lorena was good at reducing smoke和it was not efficient可知它们需要清洁、高效；根据倒数第二段首句 Their goal is to make an inexpensive stove—let's say five dollars. . . 可知要价廉；根据倒数第二段中it's safe for health and reduces global warming and deforestation可知，设计的炉子应符合现在流行的“低碳”说法。

【5】推理判断题。根据第一段和全文的内容可知，本文话题和环保有联系。D选项具有一定的迷惑性，但本文不是commercial advertisement(商业广告），最后介绍这种炉子销量好的目的旨在说明它的高效、环保和健康。全文的话题是介绍Aprovecho研究中心卓有成效的工作。
