三、
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(蝗虫) that are travelling 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 areas.
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(威胁) Sudan in the northeast of Africa. Some say it could reach Asia.
Experts say the harmful effect on crops in areas already suffering 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(公顷) per day with pesticide(杀虫剂) ,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 Food and Agriculture Organisation of the United Nations warned.
1.By using "dark cloud" to describe locusts in the first paragraph, the author of the article __________.
A.showed the relationship between rain and the locusts
B.suggested the great damage locusts have caused in the world
C.warned that locusts would sweep the continent like rain clouds
D.showed the large number of the locusts
2.What is the passage mainly about
A.Africans united effort in fighting a disaster.
B.The difficulty in controlling locusts.
C.How locusts caused great damage to West Africa.
D.A struggle to fight against a disaster brought by locusts in West Africa.
3.The locust disaster _________.
A.would be even more serious in Asia
B.is out of control
C.affected only the warning areas
D.cannot be stopped unless twice as much pesticide is provided for the affected areas
4.Which of the following is NOT TRUE according to the passage
A.Sud-FM offered a reward for fighting locusts so that more people would join in the effort.
B.Senegal is to the west of Sudan.
C.The locusts can cause such damage mainly because they have no natural enemy in West Africa.
D.12 countries affected by locusts have agreed on a plan.

答案以及解析
一、
1.答案：has shown
解析：句意为:最近,新发现的证据表明生态平衡随时可能瓦解。根据时间状语Recently可知,主句需使用现在完成时。此外,evidence为不可数名词,因此谓语动词需要使用第三人称单数形式。
2.答案：increasingly
解析：句意为:近几十年来,自然灾害变得越来越频繁。设空处修饰形容词frequent,应用副词,作状语,故填increasingly。
3.答案：involved
解析：句意为:全心投人于关爱流浪动物,她选择成为一名兽医。be involved in意为“投入于……;专心于……”,此处为形容词短语在句中作状语,故填involved。
4.答案：hitting
解析：句意为:2020年我们经历了一场艰难的战役,(因为)一场流行病袭击了武汉市。此处为“with +宾语+宾补”结构,宾语 epidemic和宾补hit之间为逻辑上的主动关系,因此使用现在分词形式。
5.答案：memorise
二、
6.答案：In sum
7.答案：claim on
8.答案：claimed damages
9.答案：is memorial to
10.答案：turning on
三、
答案：1-4.DDBC
解析：1.细节理解题。由第一段中的It is a living cloud made of billions of locusts that are travelling across the continent eating everything in their path.可知,作者想表明蝗虫的数量之多。
2.主旨大意题。通读全文可知,本文主要讲述了西非国家对抗蝗灾的斗争。
3.推理判断题。由第三、四、五段的内容可知,蝗灾已经失去了控制,形势十分严峻。
4.细节理解题。由第二段中的"We think this idea will get more people to take part in the war on the locusts,"可知A项说法正确; 蝗灾发生在西非,然后向非洲东部发展,而苏丹位于非洲东北部,由此可知B项说法正确;由第五段中的Although leaders of 12 countries have agreed on a plan, it is not expected to be enough.可知D项说法也正确。文章中没有提到C项,故C项说法错误。

答案：Dear Terry,
I'm so delighted to have received your letter. You asked me about my social practice activities during the summer vocation. Now I'd like to introduce one to you.
To begin with, I am planning to carry out a survey about the local environment with those who have shared interest. After that, we'll show our fruits to make the public know how serious the local environment is.
Undoubtedly, the social practice can provide opportunities to contact the real world outside the school.
I sincerely invite you to join me in the meaningful activities.
Looking forward to your reply.
Yours,
Li Hua
