题目列表(包括答案和解析)

[1] Imagine a magical forest where the trees touch the sky. Due to enough rainfall, the trees grow huge and spread wide. Their tallest branches are so thick-leafed that they create a thick curtain. Even the wind does not find enough space to blow as it pleases. The climate is good for life forms of all kinds- from trees to animals, birds and insects.

[2] These forests are called tropical rainforests. Most of them are located near the equator, in Asia, Africa and South America. The rainforest of the Amazon basin in South America is one of the lushest(茂盛的) rainforests in the world. You will find more varieties of trees or animal life here than anywhere else in the world.

[3] The tropical rainforests are called the green lungs of the planet. They absorb carbon dioxide from around them to process their food and release oxygen into the air. They also contain the largest number of trees with medicinal value.

[4] But now human beings are out to        . Many companies all over the world, especially in the West, have been attacking these rainforests for a variety of reasons – some want to make profit by cutting down trees and selling timber(木材); others are trying to be the only ones to make profit out of medicinal plants.

[5] To the outside world, the rainforest has always seemed a very dangerous place. Generations of films and literature have shown the people who live in the rainforests as dangerous and violent people who have a strange way of life.

[6] But actually, these people have a better understanding of their relationship with their environment than modern man has. Greed for profit by destroying the planet’s resources is a unique quality of societies that have become modern and use technology. One should then ask, who is more violent?

Glacier National Park in Montana shares boundaries with Canada, an American Indian reservation, and a national forest. Along the North Fork of the Flathead River, the park also borders about 17,000 acres of private lands that are currently used for ranching, timber, and agriculture. This land is an important part of the habitat and migratory routes for several endangered species that frequent the park. These private lands are essentially the only ones available for development in the region.?
With encouragement from the park, local landowners initiated a land?use planning effort to guide the future of the North Fork. The park is a partner in an interlocal agreement that calls for resource?managing agencies to work together and with the more than 400 private owners in the area. A draft plan has been prepared, with objective of maintaining traditional economic uses but limiting new development that would damage park resources. Voluntary action by landowners, in cooperation with the park and the county, is helping to restrict small?lot subdivisions, maintain wildlife corridors, and minimize any harmful impact on the environment.?
The willingness of local landowners to participate in this protection effort may have been stimulated by concerns that congress would impose a legislative solution. Nevertheless, many local residents want to retain the existing character of the area. Meetings between park officials and landowners have led to a dramatically improved understanding of all concerns.?
73. The passage mainly discusses ______.?
A. the endangered species in Glacier National Park?
B. the protection of lands surrounding Glacier National Park?
C. conservation laws imposed by the state of Montana?
D. conservation laws imposed by Congress ?
74. Why are the private lands surrounding Glacier National Park so important??
A. They function as a hunting preserve.?B. They are restricted to government use.?
C. They are heavily populated. 
D. They contain natural habitats of threatened species. ?
75. The relationship between park officials and neighboring landowners may best be    described as ______.?
A. indifferent                      B. intimate? C. cooperative               D. disappointing
76. It can be inferred from the passage that a major interest of the officials of Glacier     National Park is to ?______?.?
A. limit land development around the park?       B. establish a new park in Montana?
C. influence national legislation?           D. settle border disputes with Canada ?

  A vegetarian(素食者)diet may help to protect people against cancer, a UK study suggests. Analysis of data from 52,700 man and women shows that those who did not eat meat had significantly fewer cancers than those who did.

Published in American Journal of Clinical Nutrition, the findings were worth looking into .Although it is widely recommended that people eat some fruits and vegetables every day to reduce their risk of cancer and other diseases, there is very little evidence showing that a vegetarian diet can surely reduce cancers .

But surprisingly, the researchers also found a higher rate of colorectal(直肠的)cancer – a disease connected with eating red meat – among the vegetarians.

Study leader Professor Tim Key, a researcher at the University of Oxford, said no previous study had looked at the diet in this way and that there had been a lot of confusion about the issue.

“It’s interesting – it suggests there might be some reduction in cancers in vegetarians, but we need to look carefully at that”, said the professor.

More work is needed to show the connections between diet and cancer but such studies are very hard to do. Dr Joanne Lunn, a senior nutrition scientist at the British Nutrition Foundation, said the findings highlighted the fact that cancer is a complex disease and many different lifestyle factors play a part in determining a person’s risk.

73. What would be the best title for the passage?

A. Reasons for getting cancers.

B. Vegetarians get fewer cancers.

C. Tips on avoiding cancers.

D. A surprising discovery on colorectal cancer.

74. Why are the findings worth looking into?

A. They can encourage healthy eating.

B. They show that cancer is a complex disease.

C. they show a brand new discovery.

D. They have been published in American Journal of Clinical Nutrition.

75. We can learn from the passage that _________.

A. people eating red meat are unlikely to get colorectal cancer

B. the diet is one of the many factors that determine a person’s health

C. the connections between a vegetarian diet and cancer are clear through the research

D. scientists will soon figure out the relationship between the diet and cancer

Producing money requires both artistic and technological skills. Dollar bills are made so that they are interesting to look at but very hard to copy. In total, there are sixty-five separate steps required to make a dollar bill.

The money making process begins when. a yearly order is sent by the Federal Reserve Board. That order will then be divided in half. Half will be done here in Washington, D.     C.and the other half will be done in Fort Worth, Texas. Next, the Bureau orders special paper which is actually cloth since it is 75% cotton and 25% linen.

This paper is made so that it can last a long time. And, it is made with details that make it hard to copy. For example, bills contain security threads. These narrow pieces of plastic are inside the paper and run along the width of the bill. This special paper is also made with very small blue and red fibers.

Once the money is printed, guillotine cutters separate the sheets into two notes, then into individual notes. The notes are organized in "bricks," each of which contains forty one-hundred-note packages. The bricks then go to one of twelve Federal Reserve Districts, which then give the money to local banks. Ninety-five percent of the bills printed each year are used to replace money that is in circulation, or that has already been removed from circulation.

You may know that America's first president, George Washington, is pictured on the one- dollar bill. But do you know whose face is on the two, five, ten, twenty, fifty and one hundred-dollar bills? They are, in order. President Thomas Jefferson, President Abraham Lincoln, Treasury Secretary Alexander Hamilton, President Andrew Jackson, President Ulysses Grant and statesman Benjamin Franklin.

The average life span of a one-dollar bill is twenty-one months. But a ten-dollar bill lasts only about eighteen months. The one hundred-dollar bill lasts the longest, eighty-nine months. One popular question is about the two-dollar bill. This bill is not printed very often. This is because many Americans believe two-dollar bills are lucky, so they keep them. 

1.During money production, we must consider all EXCEPT that it must                    .

A.last a long time

B.be hard to copy

C.be interesting to look at

D.be done by the president's order

2.We can learn from the passage that the security threads                    .

A.are narrow pieces of plastic

B.are pressed outside the bills

C.are longer than the width of the bills

D.are actually made of cotton and linen

3.How many presidents are printed on the American money?

A. Four                 B. Five                C. Six             D. Seven

4.Why are the two-dollar bills not made often?

A.Because no one wants them.

B.Because their material is a bit more expensive.

C.Because they aren't used in America any more.

D.Because they aren't damaged quickly like other bills.

The day after news broke of a possible revolution in physics ——particles (粒子) moving faster than light ?a scientist leading the European experiment that made the discovery calmly explained it to a standing-room- only crowd at CERN.
The physicist, Dario Auterio, did not try to explain what the results might mean for the laws of physics, let alone the broader world.After an hour of technical talk, he simply said, "Therefore, we present to you today this difference, this unusualness."
But what unusualness it may be.From 2009 through 2011, the massive OPERA detector (探测器)buried in a mountain in Gran Sasso, Italy, recorded subatomic particles called neutrinos ( 中微子) arriving faster than light can move in an empty space.The neutrinos generated at CERN are hardly detectably early.If confirmed, the finding would throw more than a century of physics into disorder.
"If it's correct, it's phenomenal." said Rob Plunkett, a scientist at Fermilab, the Department of Energy physics laboratory in Illinois."We'd be looking at a whole new set of rules" for how the universe works.Those rules would bend, or possibly break, Albert Einstein's special theory of relativity, published in 1905.Basical at the time, the theory tied together space and time, matter and energy, and set a hard limit for the speed of light, later measured to be about 186, 000 miles per second.
No experiment in 106 years had broken that speed limit.Physicists expect strict study to follow, which OPERA and CERN scientists welcomed.
Fermilab operates a similar experiment, called MINOS, that shoots neutrinos from Illinois to an underground detector in Minnesota.In 2007, MINOS discovered a just detectable amount of faster than-light neutrinos, but the permissible difference of error was too big to "mention" , Plunkett said.
Fermilab scientists will reanalyze their data, which will take six to eight months.In 2013, the MINOS detector, now offline, will restart after an upgrade.It could then offer confirmation of the results.
【小题1】Why are the European scientists not sure about the results of the experiment?

A.Because they are so unexpected.
B.Because the scientists do not believe them.
C.Because the scientists are careful and calm.
D.Because they are against the present law of physics.
【小题2】The underlined word " phenomenal" in the fourth paragraph has the closest meaning to          .
A.amazingB.attractiveC.embarrassingD.sensitive
【小题3】The best title for the passage may be _____.
A.Are the laws of physics in disorder?
B.Particles faster than light; Revolution or mistake?
C.Faster than light measurement: right or wrong?
D.Is Einstein's theory still right today?
【小题4】What may be discussed in the paragraphs to follow?
A.Different opinions about the experiment.
B.How Albert Einstein's theory developed.
C.The new rules for how the universe works.
D.How Fermilab scientists will reanalyze their data.
