主题语境:人与自然　语篇类型:说明文

(2020宁夏银川期末考试)

Many of Earth’s creatures die because of humans’ choices.These choices have nothing to do with food or shelter or anything else that helps humans survive.What kills millions of animals all over the world is that humans want to make money by doing so.

People use parts of animals for everything from hats to handbags,from jewelry to ashtrays and to make powders that supposedly improve a person’s life.Deciding that a species is endangered and protecting it by law are not always enough.People who kill wildlife illegally rarely get caught.

During the late 1980s,saving elephants became a popular cause.Wildlife protection groups made sure everyone saw pictures or films of elephants with their faces cut off for their ivory.These groups also proved that certain populations of elephants were decreasing.As a result,most people stopped buying objects made of ivory.Laws against poaching(偷猎) were made stronger.Many countries made importing ivory illegal.Killing elephants for their ivory became more risky and less profitable(有利可图的).

However,concern for certain species will become weak after a while.In the late 1970s,people protested (抗议) against the killing of seal babies.Everyone was shocked to see young seals being killed in their icy habitat.The cruel activity stopped.But ten years later,the number of seal babies killed was higher than ever.

Other animal protection movements have come and gone,such as saving the whales and protecting dolphins.The whale population appears to have increased for now.And the laws are finally changed in America to protect the dolphins that swim with tuna fish in parts of the Pacific Ocean.

In the years to come,people’s attention will probably turn to some other endangered species.Plenty of them urgently need attention.During this time,will the elephants be forgotten? 

【语篇解读】作者呼吁对动物保护的关注和行动应该持续下去。

主题语境:人与自然　语篇类型:说明文

Nature has created many ways to protect creatures’ eyes.The most common protection is the eyelid—a fold of skin that closes over the eye,protecting it from damage.Eyelashes are useful for keeping out dust and other things,and tears wash away any small pieces that get through the other defenses.

Some creatures,including most birds,have three eyelids.The upper and lower lids act like human lids and keep out little tree branches,dirt,and sand.The third eyelid,however,is a semitransparent tissue(半透明组织) that crosses over the eye from the inside corner to the outside corner.Because of this protective membrane(隔膜),birds seldom have to blink.They close their eyes only when they go to sleep.For ducks,this third eyelid serves as an underwater diving mask that helps the ducks find food.

Most fish and snakes have no eyelids at all.Instead,a hard glassy covering protects their eyes.For fish,water constantly sweeps away dirt from the covering.And a snake’s eyesight is usually so bad that a little dirt obscuring its vision does not disturb it greatly.

Eyelashes defend(保护) the eye by shading it from strong light.They also act like mini brushes to remove dust.Camels have eyelashes that are four inches long to protect their eyes from wind-blown sand in the desert.

【语篇解读】大自然创造了许多方法来保护动物的眼睛。

5.Why don’t birds blink often?

A.They don’t need to sleep a lot.

B.Their upper and lower lids can keep away little branches,dirt and sand.

C.Eyelashes act like mini brushes to remove dust.

D.They have a kind of tissue to cover the eyes.

答案D

解析细节理解题。根据第二段中的“Thethirdeyelid,however,isasemitransparenttissue(半透明组织)thatcrossesovertheeyefromtheinsidecornertotheoutsidecorner.Becauseofthisprotectivemembrane(隔膜),birdsseldomhavetoblink.”可知,鸟类不常眨眼是因为它们有一种覆盖眼睛的组织。故选D项。

6.WhichofthefollowingstatementsisTRUEaccordingtothispassage?

A.Ducksdon’tclosetheireyesevenwhentheygotosleep.

B.Alittledirtdoesn’tdisturbasnake’seyesightbadlybecauseitseyesightisverygood.

C.Eyelasheshelptokeepawaysmallpiecesthatgetthroughtheothertwodefenses.

D.Somecreatureshaveahardcoveringtoprotecttheireyesinsteadofeyelids.

答案D

解析细节理解题。由第三段第一、二句可知,大多数鱼和蛇没有眼睑,取而代之的是一层坚硬的玻璃状的覆盖物保护它们的眼睛,这与D项相符合。

7.Whatcanbeconcludedfromthepassage?

A.Eyelidsaremoreimportantinprotectingcreatures’eyesthanotherdevices.

B.Creaturesdevelopdifferentmodesofeyeprotectionindifferentenvironments.

C.Birdsoftenclosetheireyesinthedaytime.

D.Afish’seyelidisahardglassycovering.

答案B

解析推理判断题。由文中的“Somecreatures,includingmostbirds,havethreeeyelids.”,“Mostfishandsnakeshavenoeyelidsatall.Instead,ahardglassycoveringprotectstheireyes.”及“Camelshaveeyelashesthatarefourincheslongtoprotecttheireyesfromwind-blownsandinthedesert.”可知,有些生物,包括大多数鸟类,有三个眼睑。大多数鱼和蛇根本没有眼睑,取而代之的是一层坚硬的玻璃状的覆盖物保护它们的眼睛。骆驼的睫毛有四英寸长,可以保护眼睛免受沙漠中风沙的侵袭。由此推断出生物在不同的环境中进化出不同的护眼模式。

答案与解析

【语篇解读】本文是一篇记叙文。文章讲述了一个爱护环境的小女孩关心保护野生动物的故事。

1.endangered　考查形容词。此处修饰名词species,应用形容词,故填endangered。

2.woke　考查动词时态。分析句子可知此处填谓语,根据found可知此处用过去式woke。

3.places　考查名词。many修饰可数名词复数,所以填places。

4.where　考查定语从句。分析句子可知therewassomewildlifeprotection作定语,修饰place,从句缺地点状语,所以应该用关系副词where。

5.an　考查冠词。elephant以元音音素开头,此处表示一头大象,所以用an。

6.without　考查介词。句意:她得知大象过去被无情地猎杀。表示“无情”可以用withoutmercy。

7.laughter　考查名词。Daisy突然笑起来。burstinto后加名词,所以填laughter。

8.rubbing　考查非谓语动词。分析句子可知本句有谓语met,所以rub要用非谓语动词的形式,monkey与rub是逻辑上的主谓关系,所以填rubbing。

9.more　考查形容词比较级。分析句子可知是和过去相比,要用比较级,所以填more。

10.fully　考查副词。此处修饰动词understood,应用副词fully。
