高中英語(yǔ)閱讀理解練習(xí)100篇 Locusts

閱讀試題

Parts of Africa are covered by a dark cloud. But this is no rain cloud. It is a living cloud made of billions of locusts (蝗蟲(chóng)) that are traveling across the continent eating everything in their path.

And now in the battle to stop this disaster, a radio station in Senegal, West Africa, is offering listeners 50 kilograms of rice if they can catch and kill 50 kilograms of locusts. "We think this idea will get more people to take part in the war on the locusts," said Abdoulaye Ba, from Sud-Fm, a radio station in one of Senegal's worst affected area.

This is West Africa's biggest locust disaster in 15 years, and it is moving east, causing huge damage to crops. As they move they produce young and increase their number and will soon threaten (威脅) Sudan in the northeast of Africa. Some say it could reach Asia.

Experts say the harmful effect on crops in areas already suf-fering from food shortage and war could cause many people to go hungry. Governments in the areas are not well equipped to fight the pest.

Although leaders of 12 countries have agreed on a plan, it is not expected to be enough. "We are now treating 6,000 hectares (公頃) per day with pesticide (殺蟲(chóng)劑), but we need to treat 20,000 hectares per day in order to have any hope of controlling this disaster," said Mohamed Abdallahi Ould Babah, director of locust control in Mauritania.

Requests are being made for international aid, which is the only way to limit the disaster, the UN's Food and Agricul-ture Organization warned.

閱讀答案

1. D 細(xì)節(jié)題。由第一段中的traveling across the continent eating everything in their path可知作者想表明蝗災(zāi)發(fā)生的規(guī)模和所造成的災(zāi)害。

2. D 主旨題。由每段首句和末段可知。

3. B 推論題。根據(jù)第三段和第四段的意思可推知。

4. C 細(xì)節(jié)題。文章中沒(méi)有被提到C項(xiàng)內(nèi)容，所以錯(cuò)了。由文第二段可知A對(duì);由…于蝗災(zāi)發(fā)生在West Africa，然后向northwest of Africa發(fā)展，而Sudan正在這一個(gè)方向，所以B對(duì);由第五段可知D也對(duì)。
