★四、阅读理解

A

The scene in the Hollywood movie TheDayAfterTomorrow, when global warming could soon turn the global climate into a new ice age,may never occur,according to new research.

The next ice age could be 15,000 years away,say European scientists who last month announced a continuous record of 740,000 years of climate data obtained from the Antarctic ice.

Scientists from 10 nations have now almost completely drilled through a 3,000-metre depth of ice high in the Antarctic mainland.They figure out that the area where summer temperatures can fall to -40℃,has at least 900,000 years of snowfalls,kept as neatly as the growth rings of a tree.And the ice and air caught in each layer(层) have begun to answer questions about the climates in the past.

The results show that there have been eight ice ages in the past 740,000 years and eight warmer periods.And by comparing the pattern of global conditions today with those of the past,the researchers reported in Nature that the present warm period could last another 15,000 years.

Research suggests that there is a very close connection between greenhouse gas levels and global average temperatures.It also shows that carbon dioxide levels are the highest for at least 440,000 years.

“If people say to you:the greenhouse effect is a good thing because we would go into an ice age otherwise,our data say no,a new ice age is not hanging over our heads,” said Eric Wolff from the British Antarctic Survey.“Now we have eight examples of how the climate goes in and out of ice ages...and you can learn what the rules are that tell us ab out the future.”

Scientists found that whenever temperatures rose in the frozen record,so did carbon dioxide level.“In 440,000 years we have never seen the greenhouse gas get as thick as it is today,” said Dr.Wolff.

1In drilling through the ice in Antarctica,scientists have found that .

A.the lowest temperature there is -40℃

B.the depth of ice is 3,000 metres

C.the ice has existed for 15,000 years

D.snowfalls are kept in certain patterns

答案:D

解析:细节理解题。第三段中的“Theyfigureoutthattheareawheresummertemperature scanfallto-40℃,hasatleast900,0 00yearsofsnowfalls,keptasneatlyasthegrowthringsofatree.”说明科学家们发现,积雪保持着一定的模式。

2The information of the global climate conditions in the past can be obtained through .

A.separating carbon dioxide from the air

B.examining the growth rings of trees

https://www.wendangku.net/doc/af14896867.html,paring temperatures in different areas

D.studying the ice and air caught in each layer

答案:D

解析:细节理解题。根据第三段中的“Andtheiceandaircaughtineachlayerhavebeguntoanswerquestionsabouttheclimatesint hepast.”可判断出对沉积在各层的雪和空气进行研究可以知道过去的气候状况。

3We can infer from Eric Wolff’s words that .

A.there is something wrong with the data

B.the greenhouse effect is always a bad thing

C.a new ice age will not come in the near future

D.the greenhouse gas will get thick in the future

答案:C

解析:推理判断题。根据倒数第二段艾瑞克·沃尔夫说的“...anewiceageisnothangingoverourheads...”可判断出,他认为新的冰川时代不会很快到来。

4What would be the best title for the passage?

A.Research over the Antarctic area

B.Warm period to last about 15,000 years

C.Report on the eight ice ages in the past

D.Hollywood movies and the global climate

答案:B

解析:主旨大意题。阅读全文可知,本文主要叙述了作者对全球气候变化的观点以及对温室效应的态度。D项明显偏离主题,可排除;A项过于笼统,没有提及气候问题;C项只是文章内容的一个侧面;只有B项适合用作标题。

B

The production of coffee beans is a huge,profitable

business,but,unfortunately,full-sun production is taking over the industry and bringing about a lot of damage.The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of certain animals and birds,and even disturbs the world’s ecological balance.

On a local level,the damage of the forest required by full-sun fields affects the area’s birds and animals.The shade of the forest trees provides a home for birds and other species(物种) that depend on the trees’ flowers and fruits.Full-sun coffee growers destroy this forest home.As a result,many species are quickly dying out.

On a more global level,the destruction of the rainforest for full-sun coffee fields also threatens(威胁) human life.Medical research often makes use of the forests’ plant and animal life,and the destruction of such species could prevent researchers from finding cures for certain diseases.In addition,new coffee-growing techniques are poisoning the water locally,and eventually the world’s groundwater.

Both locally and globally,the continued spread of full-sun coffee plantations(种植园) could mean the destruction of the rainforest ecology.The loss of shade trees is already causing a slight change in the world’s climate,and studies show that the loss of oxygen-giving trees also leads to air pollution and global warming.Moreover,the new growing techniques are contributing to acidic(酸性的) soil conditions.

It is obvious that the way much coffee is grown affects many aspects of life,from the local environment to the global ecology.But consumers do have a choice.They can purchase shade-grown coffee whenever possible,although at a higher cost.The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.

5What can we learn about full-sun coffee production from Paragraph 4?

A.It limits the spread of new growing techniques.

B.It leads to air pollution and global warming.

C.It slows down the loss of shade trees.

D.It improves local soil conditions.

解析:细节理解题。从第四段中的“causingaslightchangeintheworld’sclimate”以及“leadstoairpollutionandglobalwarming”可知B项正确。

6The purpose of the text is to .

A.entertain

B.advertise

C.instruct

D.persuade

答案:D

解析:推理判断题。从文章最后一句话“Thefuturehealthoftheplanetandmankin dissurelyworthmorethananinexpensivecupofco ffee.”可以看出作者希望人们不要为了一杯便宜的咖啡而毁了地球和人类,所以是带着劝说的意图写这篇文章的。

7Where does this text probably come from?

A.An agricultural magazine.

B.A medical journal.

C.An engineering textbook.

D.A tourist guide.

答案:A

解析:推理判断题。咖啡种植是跟农业相关的话题,所以该文可能会出现在农业杂志上,故选A项。

8Which of the following shows the structure of the whole text?

(P:Paragraph)

解析:组织结构题。本文共包括五段。第一段概述full-sun咖啡种植取代shade-grown咖啡种植已经对地球的整个生态产生了极大的负面影响。第二、三、四段分别从alocallevel,amoregloballevel以及bothlocallyandglobally三个方面阐释full-sun咖啡种植的危害。第五段归纳full-sun咖啡种植对人类多方面的影响,并提醒人们理智地对待这一问题。所以该文结构为:总—分—总。故A项正确。

1 There were few people on the Earth,and natural resources seemed to be unlimited.Today things are different.The world has become too crowded.We are using up our resources too quickly,and at the same time we are polluting our environment with dangerous chemicals. 2

Everyone realizes today if too many fish are taken from the sea,there will soon be none left.Yet,with modern fishing methods,more and more fish are caught.We know that if too many trees are cut down,forests will disappear and nothing will grow in the land.Yet,we continue to use bigger and more powerful machines to cut down more and more trees. 3 However,in most countries waste products are still put into rivers or the sea,and there are few laws to stop this.We also know that if the population of the world continues to rise,there will not be enough food in a few years.

4 If we eat more vegetables and less meat,there will be more food available for https://www.wendangku.net/doc/af14896867.html,nd that is used to grow crops feeds five times more people than land where animals are kept.

5 The world population will not rise so quickly if people use modern methods of birth control.Finally,if we educate people to think about the problems,we shall have a better and cleaner planet in the future.

A.What can we do to solve these problems?

B.Why do some people do so foolish things?

C.So we should try our best to protect the environment.

D.If we continue to do this,we won’t survive in the future.

E.Natural resources will last longer if we learn to recycle them.

F.In the past,man didn’t have to think about the environment protection.

G.We realize that if rivers are polluted with waste products from factories,we will die.
