A

More and more birds are flying to settle at Qinghai Lake,one of the highest inland lakes in China,thanks to the protection efforts of the local government.Covering an area of over 4,000 square kilometers,Qinghai Lake is also the country’s biggest salt lake.

Located in Northwest China’s Qinghai Province,the lake is famous for the two islands at its northwest point—Cormorant Island and Egg Island.The two islands have plenty of floating grass and various schools of fish,offering rich food sources to birds.The islands have become a dreamland for different kinds of groups of birds and have been called “Bird Islands”.

Each March and April,when ice and snow covering the Qinghai-Tibet Plateau(高原) start to melt,over 20 kinds of birds fly to the Bird Islands to lay eggs.During the months,flocks of birds cover the whole sky over the islands and bird eggs can be found everywhere.Visitors can hear the singing of birds from miles away.These have become a world-famous symbol of the lake.

To protect this dreamland for birds and support calls for ecological protection,China set up the Qinghai Lake National Natural Reserve at the end of 1997.Meanwhile,the State has pointed out the Bird Islands and Spring Bay of Qinghai Lake were central protection zones.

Inspectors and conservators often patrol the lake,enriching local residents’ knowledge of related laws and spreading knowledge about animal protection to visitors.They are making great efforts to call on people to love and protect the birds.At the same time,they have built special fences around the island area to prevent wolves,foxes and other carnivorous animals,as well as illegal hunters from breaking up the birds’ building nests,laying eggs and breeding.As a result,more and more birds are coming to the islands for sheltering and breeding.

1.Why are more and more birds coming to the biggest salt lake in Northwest China?

A.Because it is getting warmer and warmer.

B.Because it is being reformed.

C.Because environments there are getting more and more agreeable to them to live in.

D.Because the people there are becoming richer and richer.

2.What do the birds feed on?

A.Floating fish and various grass.

B.Grass floating on the water surface and different kinds of fish.

C.Salt water and plenty of grains.

D.Corn from the local farmers.

3.What can you infer according to the passage?

A.Over 20 kinds of birds come to the Bird Islands before March.

B.Flocks of birds fly up to the whole sky over islands to lay eggs.

C.Visitors can see the birds from miles away.

D.The government has taken many measures to protect the district.

4.Where is this passage most probably taken from?

A.A newspaper. B.A document.

C.A storybook. D.A science book.

B

What do you usually do when a flying insect lands on your arm?Most likely you blow it away.But what if that bug were a ladybug(瓢虫)?Then chances are that you would let it stay.What is it about ladybugs that we like?

Farmers once thought ladybugs were a good luck sign.A ladybug in the field meant that the crops would be successful and the weather would be good.The farmers may have been exaggerating (夸大) about what a very small bug can do,but in fact ladybugs do help out with the crops.They eat harmful insects.

Actually,it is not the adult ladybug that eats the other insects.It’s the ladybug larvae (幼虫).Ladybugs lay their eggs on leaves that are covered with aphids or other insects.When the larvae come out of the eggs,they are very hungry and will eat mites,aphids,mealybugs,green flies,and other crop-destroyers.

A single ladybug larva can eat over 1,000 aphids in one day.In the 1800s,ladybugs were brought all the way from Australia to California and set free among orange trees that were dying from being eaten by insects.The little red and black “eating machines” completely saved all the trees.

Ladybugs go about their daily business without worrying much about anything.Very few birds or insects will eat a ladybug because it gives off something that is dangerous to eat.Ladybugs also protect themselves by playing dead.They fall off leaves and remain very still until their enemy goes away.

So next time you see a ladybug,think about what it may be up to.Maybe it is off to save an orange tree.Maybe its next move will be to fall off a leaf and play dead or stand up to a bird about 100 times its size.Maybe it’s letting you know that the weather will be good tomorrow.Who knows?Ladybugs are special that way. 

5.What do we know about mites and aphids?

A.They do harm to the crops.

B.They eat more than they should.

C.They are food for adult ladybugs.

D.They are the enemy of ladybug larvae.

6.Why were ladybugs brought from Australia to California in the 1800s?

A.To report the weather for farmers.

B.To increase their number.

C.To do research on them.

D.To save orange trees.

7.What does the underlined part “stand up to” in the last paragraph probably mean?

A.Play with. B.Worry about.

C.Get along with. D.Fight back against.

8.What does the author think of the ladybug?

A.It is a crop-destroyer.

B.It is a good luck sign.

C.It is a little flying helper.

D.It is a big eating machine.

Ⅴ.语法填空

Ⅳ.【语篇导读】本文是一篇时文报道类文章,讲述了越来越多的鸟来到青海湖,当地政府的保护措施使这个地方成为鸟类的乐园。政府向人们普及鸟类保护法,号召人们保护鸟类。

1.C　推理判断题。根据第一段中的“More and more birds are flying to settle at Qinghai Lake,one of the highest inland lakes in China,thanks to the protection efforts of the local government.”以及下文的内容可知,越来越多的鸟飞到青海湖栖息一方面是由于当地政府对于环境保护所做出的努力,另一方面是那里有充足的食物来源,也就是说那里的环境越来越适合鸟类生存。故选C项。

2.B　细节理解题。根据第二段中的“The two islands have plenty of floating grass and various schools of fish,offering rich food sources to birds.”可知,两个岛上有丰富的浮草与各种鱼类,为鸟提供丰富的食物。故选B项。

3.D　推理判断题。根据第四五段的内容及第一段中的“thanks to the protection efforts of the local government”可知,D项正确。故选D项。

4.A　推理判断题。通读全文可知,本文讲的是由于当地政府对环境的保护,越来越多的鸟来到青海湖。这篇文章很有可能出现在报纸上,是一篇新闻报道。故选A项。

【语篇导读】本文是一篇说明文。瓢虫是一种益虫,是庄稼的好帮手。本文对瓢虫进修了详细的介绍。

5.A　推理判断题。由第三段中的“mites,aphids,mealybugs,green flies,and other crop-destroyers”可知,这些都是对庄稼有害的虫子。

6.D　细节理解题。由第四段中的“ladybugs...set free among orange trees that were dying from being eaten by insects”可知,十九世纪瓢虫被从澳大利亚带到加利福尼亚州是为了挽救被害虫侵害的橘子树。

7.D　词义猜测题。由倒数第二段中的“Very few birds or insects will eat a ladybug because it gives off something that is dangerous to eat.”可知,很少有鸟或昆虫吃瓢虫。再由画线部分后的“a bird about 100 times its size”可知,当遇见比它大的鸟时,瓢虫会释放某种物质从而对鸟造成威胁。故此处的stand up to有“回击、抵御”之意。

8.C　推理判断题。本文旨在介绍瓢虫这种能够吃害虫的昆虫,它们对于庄稼来说是得力的帮手。C项中的helper最符合瓢虫的这一特性。

Ⅴ.【语篇导读】本文是一篇说明文。青蛙是一种对人类有益的动物。但是现在青蛙越来越少了。这是因为它们的头号敌人——人类杀死了它们,把它们当成了美味佳肴。所以我们必须尽快采取措施拯救青蛙。

1.happily　考查词性转换。此处修饰现在分词singing,应使用副词形式,意为“快乐地歌唱”。

2.insects　考查名词复数。insect是可数名词,前面没有修饰词,应使用复数形式。

3.as　考查介词。be regarded as “被认为是……”为固定短语。

5.on　考查介词。put sth on the table“把某物放在桌子上”。

6.responsible　考查词性转换。be responsible for意为“为……负责”。此处在从句中作表语,应使用形容词。

7.eating　考查非谓语动词。此处的逻辑主语是frogs,当时间状语从句的主语与主句主语一致且从句谓语含有be动词时,可以省略从句的主语和be动词。此处为while frogs are eating...的省略形式。

8.to save　考查非谓语动词。不定式表目的。

9.who　考查定语从句。此处为定语从句,先行词是those,指人,关系词在从句中作主语,应使用关系代词who引导。

10.will be punished考查时态和语态。根据语境和句意可知,此处用 一般将来时的被动语态。
