Question

【題目】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】 猜測詞義題。根據(jù) the richer people use oil and gas 可以排除A項。第一段中介紹發(fā)展中國家人們使用wood, crop waste, animal waste or coal, 而 biomass 所在的句子為 People having less money use wood or biomass for cooking, 故可排除 B項，煤炭也是需要花錢的，因此不怎么花錢的燃料除了木頭就是 crop waste 和 animal waste.

【2】 推理判斷題。根據(jù)第一段末尾句But they are also a major cause of health problems and death. 可知。

【3】細節(jié)理解題�？梢赃\用排除法，根據(jù)In the late 1970s, Aprovecho produced a popular stove called the Lorena. 可知 A選項錯誤。

【4】推理判斷題。根據(jù)第四段中The Lorena was good at reducing smoke和it was not efficient可知它們需要清潔、高效；根據(jù)倒數(shù)第二段首句 Their goal is to make an inexpensive stove—let's say five dollars. . . 可知要價廉；根據(jù)倒數(shù)第二段中it's safe for health and reduces global warming and deforestation可知，設(shè)計的爐子應符合現(xiàn)在流行的“低碳”說法。

【5】推理判斷題。根據(jù)第一段和全文的內(nèi)容可知，本文話題和環(huán)保有聯(lián)系。D選項具有一定的迷惑性，但本文不是commercial advertisement(商業(yè)廣告），最后介紹這種爐子銷量好的目的旨在說明它的高效、環(huán)保和健康。全文的話題是介紹Aprovecho研究中心卓有成效的工作。
