Question

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) and they are eating everything in their path.
And now in order to fight against this disaster, a radio station in Senegal, West Africa, is offering listeners 5 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 fight against 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. Now it is moving east and it leads to the loss of crops. When they move, they have babies, so their number is getting bigger. and will soon threaten (威脅) Sudan in the northeast of Africa. Some say it may reach Asia.
Experts say many people in the areas will go hungry because of this disaster. What’s worse, governments in the areas don’t have enough things to fight the locusts.
Although leaders of 12 countries have agreed on a plan, it is not enough. ‘We are now treating 6,000 hectares (公頃) per day with pesticide (殺蟲劑), 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, leader of locust control(控制) in Mauritania.

試題分析：這篇短文講述的是非洲的部分地區遭受了非常嚴重的蝗蟲災害，造成了很大的損失�，F在政府及其他國家的領袖都已經采取措施，展開行動，消滅蝗蟲。電臺也呼吁更多的人加入到與蝗蟲的戰斗中來。
小題1:推理判斷題。文章的開頭用a dark cloud 一片黑云來形容蝗蟲，是想向我們表明蝗蟲的數量非常之多，移動速度之快，以及蝗蟲造成的損失有多么嚴重。故選D。
小題2:推理判斷題。根據文章的最后一段，我們可以知道，為了控制住蝗蟲導致的災害，每天需要用殺蟲劑來清理20，000公頃的土地，但是現在的狀況是每天只能清理6，000公頃的土地，所以如果沒有更多的殺蟲劑，蝗蟲的災害是無法停止的。故選D。
小題3:細節理解題。根據文章中…is offering listeners 5 kilograms of rice if they can catch and kill 50 kilograms of locusts.可知，人們每殺死50公斤的蝗蟲，便可得到5公斤的大米，故經過計算，殺死450公斤的蝗蟲，可以得到45公斤的大米，故選D。
小題4:推理判斷題。根據文章This is West Africa’s biggest locust disaster in 15 years可知Senegal在非洲的西部，而Sudan在非洲的Sudan in the northeast of Africa.東北部，故Senegal應該在Sudan的西南部，故B選項說Senegal在Sudan的東南部是不對的。故選B。根據文章的第二段我們可知A是正確的；根據文章第四段可知C是正確的；根據文章的最后一段可知D是正確的。
小題5:主旨大意題。這篇文章主要講的是非洲西部發生的嚴重的蝗蟲災害，而且各方面正為消滅蝗蟲而做著努力，故選D。B、C兩個選項都只是文章內容的一部分，不全面。A選項的表示不正確，為消滅蝗蟲的災害，不只是非洲西部的國家在做著努力。故選D。
