    The total continent of Antarctica, from its mountains to the seas full of blue whales, emperor penguins and leopard seals, is, by means of international agreement, classified as a nature preserve. The Antarctic Treaty took effect in 1998, and doesn’t allow mining and oil drilling for at least fifty years anywhere within the boundaries of Antarctica. The treaty places a strong emphasis on the protection of the natural environment but not development. All wildlife threats including dogs and chemicals used for killing pests are also banned.

    The agreement has been set by some countries to keep Antarctica free of commercialism and industrial development. This agreement was signed in 1991 by the 26 leading nations with scientific interest in the land. Some of the nations in the agreement are the United States, Russia, China, India, Japan, Argentina, Brazil, and most of the primary European nations.

    The rules made by this treaty ended over 15 years of lobbying(游說)by environmental groups and put a stop to diplomatic(外交的)talks. In addition to preventing all oil drilling and mining, the 35 scientific outposts(前哨站) on Antarctica are required to remove all rubbish and clean up all places where unwanted waste is left. It keeps scientific stations from discharging untreated waste water into the surrounding waters.

     Sled dogs were what explorers like Norway’s Roald Amundsen used to reach the South Pole in 1911. Dogs, however, were banned because they are a recent danger to the penguins and other native birds.

    With laws enforced(實(shí)施)in 26 nations, each nation will be responsible for enforcing the rules individually. If the country’s government refuses to become involved when its citizens disobey the rules, the other nations would apply pressure to solve the issue. There are many people who see this treaty as an environmental success story.

55. The Antarctic Treaty was signed to ________.

A. attract more tourists to Antarctica

B. protect the environment of Antarctica

C. forbid diplomatic talks between countries

D. promote scientific research on Antarctica

56. Dogs are forbidden on Antarctica because they________ .

A. may pollute the surrounding environment

B. are a threat to the birds there

C. are of little use there

D. may face a great threat

57. We can infer from the text that________.

A. environmental groups are satisfied with the Antarctic Treaty

B. it is difficult to enforce the treaty

C. there are no natural resources on Antarctica

D. tourism is not allowed on Antarctica

58. Which of the following is TRUE about the Antarctic Treaty?

A. Some countries have broken the rules of it.

B. It was signed in 1998.

C. It’s effective in protecting the environment of Antarctica.

D. It fails to achieve its original purpose.

World Expo 2010 Shanghai China is to be staged in Shanghai from May 1 to October 31, 2010. If you plan to visit the Shanghai Expo this summer, China Pavilion(館)is a must - see area for you.
China Pavilion, which is called Oriental Crown, is located at the center of the Expo site. Standing 63 meters tall, the China Pavilion takes the shape of an emperor's crown, with the upper layers larger than the lower ones. Covering 160,000 square meters in floor space, the pavilion is made up of a national hall and a regional(宗教的  ) hall. Buildings on the China Pavilion began on Dec. 18, 2007. The design of the China Pavilion was picked from a total of 344 designs put for­ward by Chinese from around the world. The pavilion has both traditional and modern features, which helps devel­op the theme of the 2010 Expo; "Better City, Better Life. For example, it is red in appearance, which covers the  traditional Chinese culture, and it is green indoors, with the use of energy - saving techniques. The Shanghai World Expo is expected to attract 70 million visitors from across the globe. It is estimated that 400,000 people will visit the Expo and its 140 pavilions every day during the period, but the China Pavilion is only able to receive about one tenth of the total. How to hold so many people in the pavilion remains a tough task. Luckily, the China Pavilion is built as a permanent(長(zhǎng)久的) landmark.
During the Expo, the main structure(結(jié)構(gòu)  ) will be used for an exhibition based on the theme of “ Chinese wisdom in urban (城市)development” by explaining the values of harmony(和諧  ), nature and spirit. The three - story pavilion has three sections. The top floor's “Footprint of the East” will show some of the changes in Chinese cities. There, you can see a film which shows how Chinese cities have changed, especially in the past 30 years. According to Lu Chuan, director of the film, the scenery is like something from Lord of the Rings. On the second floor, “Journey of Wisdom” will explain China's four great inventions.  And the ground's “ Blossoming” City will display scenes from cities of the future.
【小題1】 Which of the following words can be used to describe the China Pavilion?

A.Tiny.B.ImaginationC.ForeignD. Environment - friendly.
【小題2】The China Pavilion can receive________visitors at most per day.
A.20,000B.40,000C. 100,000D.400,000
【小題3】We can infer(推斷   )that________.
A.Some foreign friends took part in the designs of the China Pavilion
B.You can continue to visit the Japanese Pavilion after the Expo is over
C.China Pavilion will be pulled down after the World Expo 2010 is over
D.China Pavilion will continue to be open to visitors after the Expo is over
【小題4】 On the second floor, you can________.
A.enjoy a film about the changes of cities in China
B.learn what Shanghai looked like in the 1920's
C.find out how paper was invented
D.see how Chinese cities will look like in the future

科目:高中英語 來源:2011河南信陽高中畢業(yè)班第二次調(diào)研考試英語試卷 題型:閱讀理解

Dear editor,
I am Paul , a senior English teacher in Linchuan No. 1 Middle School in Jiangxi Province , China. This letter is written to ask for your opinion.
The other day, I met with a multiple - choice exercise. We teachers argued heatedly with each other over its answer. Unfortunately, neither side could convince the other. The sentence is to be attached at the end of the letter. There is no doubt that the reference answer C is correct. But I don’t  think it is the only answer. Personally, I do think A is also a reasonable choice in sense as well as in grammar, if the case is treated from another aspect.                                
What puzzles me is why we should deal with so many multiple - choice exercises with not rigorous(嚴(yán)謹(jǐn)?shù)模〆nough reference keys. But being a teacher, it’s very important and necessary to make it clear to students which answer is correct, which is more appropriate, and which is the best one. Regrettably, Multiple - choice test, which is a bit old - fashioned in western countries, seems to be quite popular and covers a rather high percentage in all sorts of English tests in China, especially in NMET.
Personally speaking, I don’t think multiple - choice test form making up more than 75 percent of the total scores in college entrance examination is a very good and effective testing method. Instead, more subjective testing forms depending on one’s own thinking and his ability to use the language like key words falling, question answering, paragraph or passage summarizing, English - Chinese or Chinese - English inter - translation, etc. should be applied to English proficiency tests. Through the test forms mentioned above, students’ ability to use the language will be better developed. Consequently, more advanced and outstanding English learners could be picked out. In fact, a test paper focusing on multiple - choice test influences, in a sense, students to form their own language thinking, which hinders(阻礙)the development of their language ability as well. Do you think so?
I am looking forward to your authoritative opinion. Thanks.
Yours sincerely,
Paul Liao
【小題1】.
. What can be learnt from the letter is that the writer ________.

A.writes to argue with the editor over China’s present test system
B.thinks the reference answer to the sentence is completely wrong
C.thinks subjective test forms constitute a rather high percentage in NMET
D.doesn’t think highly of China’s present English proficiency test forms
【小題2】.
. In order to better develop students’ ability to use English, the writer suggests ________.
A.dealing with more multiple - choice exercises
B.laying stress on the practice of subjective exercises
C.a(chǎn)rguing hotly with teachers over reference answers
D.considering a problem from different aspects
【小題3】.
Which of the following does NOT belong to subjective exercises in English learning?
A.Keeping a diary.B.Summarizing a paragraph.
C.Copying a test.D.Translating a passage.
【小題4】.
The writer seems to feel ________ as to the future development of students’ language ability.
A.concernedB.curiousC.confusedD.satisfied

科目:高中英語 來源:2012-2013學(xué)年廣東省高三第一次月考英語試卷(解析版) 題型:閱讀理解

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.

In the past hundred years, humans have begun destroying rainforests in search of three major resources (資源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.

There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.

Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.

1.Why did humans destroy rainforests in the past hundred years?

A.They tried to get crops and paper

B.They needed other products

C.They wanted to raise farm animals

D.They aimed to get three major resources.

2.Rainforests can help to adjust the climate because they________.

A.reflect more heat into the atmosphere

B.bring about high rainfall throughout the world

C.rarely cause the temperature to drop lower than 16℃

D.reduce the effect of heat from the sun on the earth

3.What does the word “this” underlined in the third paragraph refer to?

A.We will lose much more than we can gain.

B.Humans have begun destroying rainforests.

C.People have a strong desire for resources.

D.Much carbon dioxide comes from burning rainforests.

4.It can be inferred from the text that________.

A.we can get enough resources without rainforests

B.there is great medicine potential in rainforests

C.we will grow fewer kinds of crops in the gained land

D.the level of annual rainfall affects wind patterns

5.What might be the best title for the text?

A.How to Save Rainforests

B.How to Protect Nature

C.Rainforests and the Environment

D.Rainforests and Medical Development
