About 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink sea water, how can it be important?
Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important sea water is!
Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced.
The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn’t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.
Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important sea water is!
46. Which of the following is the proper order of the food chain?
A. small animals→algae→microscopic animals→large animals→man
B. algae→microscopic animals→large animals→larger animals→man
C. small animals→algae→large animals→microscopic animals→man
D. microscopic animals→algae→large animals →larger animals→man
47. People used to think that the rubbish thrown into the sea ________.
A. wouldn’t harm the fish in the sea   B. would change the balance of the food chain
C. would be broken down in the sea   D. wouldn’t do much harm to the sea
48. From the passage, we learn that _________.
A. most fish and sea animals live at the surface of the seas
B. it is very difficult to break the balance of a food chain
C. excessive fishing has caused the decrease in fish stock
D. it won’t be long before the problems concerning oceans will be solved
49. Which of the following is NOT a way being used to protect oceans?
A. The use of international agreements.
B. Forbidding fishing to protect fish stocks.
C. The use of new techniques.
D. Raising people’s awareness of the need to protect oceans.
50. What would be the best title of the passage?
A. The importance of seawater.
B. Life in the oceans.
C. How to protect food chains.
D. How to deal with seawater pollution.

Students throughout the world spend their money in different ways. A detailed study on student spending indicated that young people"s spending habits have changed greatly over the past few years. The study also says that the change is about the same around the world, however. Here are some examples of popular student spending habits---both healthy and also unhealthy---around the world today.
Students these days have too much brand awareness, so their spending on clothes is now quite high. On average, students buy one or two complete sets of new clothes each month, and this makes their total spending higher.
Student spending shows quite an up-and-down pattern as they get older. Students spend a lot more money in high school than before their high school years because when they enter high school, their exposure (接触到) to branded goods increases. As the students get close to graduation, their expenses start to go down. This is the time when they have to become more responsible about money and start to understand its importance.
Students also spend a lot more on entertainment than their parents did when they were young, because of the easy access to entertainment these days. Shopping is considered to be quite entertaining because of all the different forms of amusement presented by shopping malls. These attract students to buy things.
Student spending on food hasn"t increased much, but there has been a marked increase in the use of alcohol. There are several more places in which students can drink now. The culture of having parties has also grown a lot among students too, and students usually end up spending a lot on alcohol in such places.
This is not such a bad situation, actually. The study indicates that although student spending has shot through the roof, at the same time, they are financially much stronger today than they were in the past. This is compensation (补偿，回报), and probably it is just another branch of the life that we are living in this speedily advancing world.
60. What is the passage mainly about?
A. Unhealthy student spending habits.
B. Why student spending is changing.
C. How a student should spend money.
D. A study on student spending.
61. Why do students spend less money just before graduation?
A. They see fewer products.
B. They are more conscious of the value of money.
C. They have no time to entertain themselves or go shopping.
D. Their spending on clothing goes down.
62. What can we learn from the passage?
A. Student spending habits are becoming worse and worse.
B. Today"s students spend more money on entertainment than on clothing.
C. Today"s students are better at earning money than their parents.
D. Student spending on food has increased the least.
63. Which of the following best shows the structure of the passage?
①Paragraph 1; ②="Paragraph" 2; ③="Paragraph" 3; ④="Paragraph" 4;
⑤="Paragraph" 5; ⑥="Paragraph" 6;

In nineteen ninety-nine, twelve percent of public elementary schools in the United States required students to wear uniforms. Just three years later, estimates were almost double that.
A study of six big-city Ohio public schools showed students who were required to wear uniforms had improved graduation, behavior and attendance rates. Academic performance was unchanged.
Some middle and high schools in Texas have also joined the movement. Yet studies find mixed results from requiring uniforms. And some schools have turned away from such policies.
Supporters believe dressing the same creates a better learning environment and safer schools. The school district in Long Beach, California, was the first in the country to require uniforms in all elementary and middle schools. The example helped build national interest in uniforms as a way to deal with school violence and improve learning.
Findings in Long Beach suggested that the policy resulted in fewer behavior problems and better attendance. But researcher Viktoria Stamison, who has looked at those findings, says they were based only on opinions about the effects of uniforms.
She says other steps taken at the same time to improve schools in Long Beach and statewide could have influenced the findings. The district increased punishments for misbehavior. And California passed a law to reduce class sizes.
In Florida, for example, researcher Sharon Pate found that uniforms seemed to improve behavior and reduce violence. In Texas, Eloise Hughes found fewer discipline problems among students required to wear uniforms, but no effect on attendance.
Sociologist David Brunsma has studied school uniform policies since nineteen ninety-eight. He collected the reports in the book. In his own study, he found that reading and mathematics performance dropped after a school in rural Pennsylvania required uniforms.
Political and community pressures may persuade schools to go to uniforms to improve learning. But David Brunsma and others believe there is not enough evidence of a direct relationship. In fact, he says requiring uniforms may even increase discipline problems.
52. What’s the main idea of this passage?
A. More and more students are required to wear uniforms in the US.
B. Wearing uniforms contributes to good academic performance.
C. Researchers in the US argue for school uniform policies.
D. Evidence for school uniform policies in the US is seen as weak.
53. Which was/were the first in the US to require uniforms in all elementary and middle schools?
A. Six big-city Ohio public schools.
B. The school district in Long Beach, California.
C. Some middle and high schools in Texas.
D. Some elementary and middle schools in Florida.
54. Which of the following researchers are NOT supporters of school uniform policies?
A. Viktoria Stamison and Sharon Pate.
B. Sharon Pate and David Brunsma.
C. Eloise Hughes and Sharon Pate.
D. Viktoria Stamison and David Brunsma.
55. The underlined word “misbehavior” in the sixth paragraph probably means ______.
A. serious crime            B. bad performance
C. absence for class       D. action against wearing uniforms
56. We can infer from the passage that ______.
A. more work is needed to get better information about uniform’s effect

There is no doubt that adults, and even highly educated adults, vary greatly in the speed and efficiency of their reading. Some proceed very lowly throughout; others dash along too quickly and then have to regress. Poor readers in particular may lack the ability to vary their manner of reading according to the type of reading matter and to their intentions in reading it. A good reader can move at great speed through the text of a novel or similar light reading matter. He may be able to skim a page, picking up a word or two here and there, and gain a general idea of what the text is about without really reading it. In reading more difficult material, with the intention of taking in the whole of it, he will proceed more slowly, but even then he will vary his pace, concentrating on the key words and passages, perhaps re-reading them several times and pass more quickly over the remainder. A less efficient reader tends to maintain the same speed whatever the material he reads. Consequently, even light reading matter gives him little pleasure because he reads so slowly. But this pace may be too fast for really difficult material which requires special concentration at difficult points.
A type of reading which necessitates(需要) careful attention to detail is proofreading, in which the reader, in order to detect misprints in a sample print, has to notice not so much the meaning of what he reads as the exact shape and order of letters and words in the text. This is extremely difficult for most people, since they are accustomed to overlooking such details. In fact, considerable practice is required to practise this task efficiently and it can be done only by reading very slowly, and by paying comparatively little attention to the general meaning of the text.
68．This article is mainly concerned with ________.
A．the ability to read fast
B．difference in the speed and efficiency of reading
C．different reading skills
D．the reading speed of highly educated adults
69．According to the article, there is a difference in reading speed ________.
A．among adult readers
B．among young educated people
C．among readers who have different experiences
D．between the poorly educated and the highly educated
70．The underlined word "regress" can be best replaced by "________".
A．regret         B．stop   C．move slowly       D．go back
71．The author believes a good reader should ________.
A．always read at great speed
B．read carefully and catch every detail
C．always review the text he has read
D．change his speed according to the type of text

The hole in the Earth"s ozone layer (臭氧层) has until now protected Antarctica from the worst effects of global warming. But scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3℃on average, with melting ice contributing to a global sea level increase of up to 1.4 metres.
In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, paradoxically, been cooling, resulting in a 10% increase in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctica, making much of the continent surface colder than usual.
But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an increase in average air temperatures of around 3℃ and a reduction in sea ice by around a third.
The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly. "Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctica has already resulted in a 10% rise in global sea level in recent decades.
Johnson believes that international action to reduce global warming is required immediately or it may be too late. "Everything is connected - Antarctica may be a long way away but it is an important part of the Earth"s system," said Johnson. "It contains 90% of the world"s ice, 70% of the world"s fresh water and that is enough, if it melts completely, to raise sea levels by 63 metres."
Even in a worse-case situation scientists don"t expect the ice to entirely disappear, but predict that, because of the melting ice sheets, average sea level rise will be around 1.4 metres higher by the end of the century.
63. The underlined word "paradoxically" (in Paragraph 2) most probably means "__".
A. rapidly         B. approximately    C. contradictorily    D. apparently
64. What is the effect of the hole in the ozone layer on Antarctica?
A. It is causing the ice to melt faster.
B. It is making much of the continent colder.
C. It is making the effects of global warming in the region worse.
D. It is reducing the amount of water in Antarctica.
65. What do scientists think is the biggest danger facing Antarctica?
A. Rising sea levels.                  B. Warming sea water temperature.
C. Water pollution.                      D. Growing ice sheets.
66. Which of the following is true according to the passage?
A. Antarctica is currently experiencing the full effects of global warming.
B. The average temperature has increased by 3℃ in recent decades.
C. Antarctica contains most of the world"s fresh water.
D. Ten percent of Antarctica"s ice has already been lost.
