從A、B、C、D四個(gè)選項(xiàng)中，選出一個(gè)可以填入空白處的最佳選項(xiàng)，并在答題卡的相應(yīng)位置上涂黑。

Burning coal to provide energy adds planet-warming carbon dioxide, or CO2, to Earth’s atmosphere. As the planet heats up, experts warn that simply cutting greenhouse gas emissions (排放) will not be enough to avoid possibly disastrous levels of global warming. CO2 must also be obliterated from the atmosphere, they say.

Existing experimental machines that remove CO2 directly from the air are too costly to be widely used. But a new report from the U.S. National Academy of Sciences, Engineering and Medicine says effective carbon-removal technology already exists. It is not costly, or even complex science. It’s forests.

The report explains that planting trees and overseeing forests are cost-effective ways to clean the air. They also work well across large areas. Forests used to cover much of the Appalachian Mountains in the eastern United States. In the state of West Virginia, a kind of mining known as strip mining (露天開采) left the land there bare, without trees. Now experts are working to bring back the forests that once covered much of the state.

West Virginia’s Monongahela National Forest is home to a rare group of trees. They are called virgin (原始的) woods; they have never been touched by humans. Shane Jones, a biologist with the U.S. Forest Service, says the trees there were missed by mistake when the surrounding forest was cut down for wood many years ago. That mistake turned out to be a good thing; red spruce (云杉) forests such as those in the Monongahela are extremely effective at taking CO2 out of the atmosphere and locking it into the soil.

Experts say, nature offers powerful tools to fight climate change.

1. What’s the advantage of forests compared with the existing experimental machines?

A. They release more oxygen.

B. They clear more CO2.

C. They save more money.

D. They absorb CO2 faster.

1.【答案】C

【解析】細(xì)節(jié)理解題。由第二段中第二句“effective carbon-removal technology already exists. It is not costly, or even complex science. It’s forests”可知，有效的去除二氧化碳的技術(shù)已經(jīng)存在。它花費(fèi)不高，甚至不是復(fù)雜的科學(xué)。它就是森林。因此，與現(xiàn)有的試驗(yàn)機(jī)相比，森林的好處是省錢。故選C。

2. Why does the author mention West Virginia in Paragraph 3?

A. To prove the place is unsuitable for human survival.

B. To stress planting trees is practical for clean air.

C. To indicate trees are difficult to live on such poor soil.

D. To show people in the state are now living a hard life.

2.【答案】B

【解析】推理判斷題。由題干中的 West Virginia 可將本題答案定位在文章第三段內(nèi)。由其中前兩句“The report explains that planting trees and overseeing forests are cost-effective ways to clean the air. They also work well across large areas.”可知，植樹造林是劃算的清理空氣的方法。它們也適合大面積的使用。因此，本段中的舉例是為證明用植樹造林來清理空氣是切實(shí)可行的。故選B。

3. What can we know about the red spruce trees?

A. They can only be found in Monongahela National Forest.

B. They were given the name virgin woods for beauty.

C. They were cut down for wood by farmers.

D. They could store carbon dioxide in the soil.

3.【答案】D

【解析】細(xì)節(jié)理解題。由第四段最后一句“red spruce (云杉) forests such as those in the Monongahela are extremely effective at taking CO2 out of the atmosphere and locking it into the soil.”可知，像莫農(nóng)加希拉的這些云杉在吸收空氣中的二氧化碳，并將它們鎖在土壤內(nèi)這些方面是極其有效的。因此，云杉能將二氧化碳儲存在土壤中。故選D。
