It is often necessary to release a fish, that is , set it free after catching, because it is too small, or you just don’t want to take it home to eat. In some cases, releasing fish is a good measure that will help keep fish variety and build their population size. The Department of Game and Inland Fisheries (DGIF) encourages fishermen who practice catch-and-release fishing to use a few simple skills when doing so. The advice provided below will help make sure that the fish you release will survive to bite again another day.
—When catching a fish, play it quickly and keep the fish in the water as much as possible. Don’t’ use a net in landing the fish and release it quickly to prevent it from dying.
—Hold the fish gently. Do not put your fingers in its eyes. Don’t wipe the scales (鱼鳞) off the fish because it might cause it to develop a disease and reduce its chance of survival.—Remove your hook quickly. If the hook is too deep or hooked in the stomach, cut the line and leave the hook in. The hook left inside will cause no serious problem to the fish.
—Take good care of the fish by moving it gently in water. Release the fish when it begins to struggle and is able to swim.
—Do not hold fish in a bucket or some other containers and later decide to release it. If you are going to release a fish, do so right away.
With a little care and by following the suggestions given above, you can give the released fish a better chance of survival.
41. People sometimes set a fish free after catching it because they _________
A. don’t want it to die
B. hope it will grow quickly
C. don’t want to have it as food
D. want to practice their fishing skills
42. Which of the following will probably make a fish ill?
A. Taking the hook off it.
B. Removing its scales.
C. Touching its eyes.
D. Holding it in your hand.
43. A proper way to release a fish is to _________.
A .move it in water till it can swim B. take the hook out of its stomach
C. keep it in a bucket for some time
D. let it struggle a little in your hand
44. What is the purpose of the test?
A. To show how to enjoy fishing.
B. To persuade people to fish less often.
C. To encourage people to set fish free.
D. To give advice on how to release fish.
B
People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man's release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance , such as oil tankers into the sea.
The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new and complex goods are produce there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing populations. However, the land itself is gradually becoming worn out as it is being used in some cases, too heavily, and artificial fertilizer cannot restore the balance.
Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in term of glass, metals and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying ,excess consumption and careless disposal of the products we use in our daily lives.
45. The underlined phrase ―disposed of ‖in the second paragraph means_______.
A. dealt with
B. exposed
C. disapproved of
D. collected
46. In the writer’s view ,the more new goods, _______.
A. the less pollution
B. the harder pollution can be prevented
C. the more pollution there will be
D. the more easily pollution can be controlled
47. What can we learn from the last paragraph?
A. We can do much to reduce pollution.
B. The government is trying hard to stop pollution.
C. Individuals know how to get rid of the habit of littering everywhere.
D. We can’t stop buying unnecessary things.
48. People can help solve the problem of pollution by _______.
A. urging their governments to control litter and waste
B. making anti-pollution advertisements
C. cutting down the use of oil and other oil products
D. reducing unnecessary buying, over-consumption and careless disposal of wastes
C
It is difficult to imagine what life will be like without memory．The meanings of thousands of everyday perceptions(感觉、知觉), the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory．
Memory can be defined as the capacity to keep information available for later use．It includes not only ―remembering‖ things like arithmetic or historical facts, but also involves any change in the way an animal typically behaves．Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile．Memory is also involved when a six-year-old child learns to swing a baseball bat．
Memory exists not only in humans and animals but also in some physical objects and machines．Computers, for example, contain devices from storing data for later use．It is interesting to compare the memory-storage capacity of a computer with that of a human being．The instant-access memory of a large computer may hold up to 100,000 ―words‖—ready for instant use．An average U．S．teenager probably recognizes the meaning of about
100,000 words of English．However, this is but a fraction(部分、片断) of the total amount of
information which the teenager has stored．Consider, for example, the number of faces and places that the teenager can recognize on sight．
The use of words is the advanced problem-solving intelligence of human beings．A large part of a person’s memory is in terms of words and combinations of words．
49．According to the passage, memory is considered to be ________．
A．the basis for decision making and problem solving
B．an ability to store experiences of future use
C．an intelligence typically possessed by human beings
D．the data mainly consisting of words and combinations of words
50．The comparison made between the memory capacity of a large computer and that of a human being shows that ________．
A．the computer’s memory has a little bigger capacity than a teenager’s
B．the computer’s memory capacity is much smaller than an adult human being’s
C．the computer’s memory’s capacity is much smaller even than a teenager’s
D．both A and B
51．The whole passage implies that _______．
A．only human beings have problem-solving intelligence
B．a person’s memory is different from a computer’s in every aspect
C．animals are able to solve only very simple problems
D．animals solve problems by instincts rather than intelligence
52．The topic of the passage is __________．
A．What would life be like without memory?
B．Memory is of vital importance to life．
C．How is a person’s memory different from an animal’s or a computer’s?
D．What is contained in memory?
D

The new iPhone 3G should please everyone. Its look and feel are only slightly improved, but a faster network loads Web pages more quickly, true GPS functionality allows it to easily
find places nearby, and the new $199 price (down from $400) makes it an affordable luxury. Before deciding whether to buy, however, make sure you can actually take advantage of the iPhone 3G's high-speed data network. 3G stands for third-generation, which in non-geek speak translates to Web pages and mail messages that, ideally, load about three times faster than on the original iPhone. Even better, 3G coverage enables you to make a phone call and surf the Web at the same time. That's great, if you live or work in a place where the 3G network of AT&T （美国电话电报公司） (the sole wireless carrier of the iPhone) is active. That's not so great in cities like New York where AT&T's cellular coverage is awful. As one of my colleagues in New York City, who bought the original iPhone, commented, "It's just a toy. You can't make phone calls on it, so I carry my Verizon phone with me all the time."
The real fun begins when you tap on the icon called "App Store" and start browsing the hundreds of add-on applications that have been developed just for the iPhone. You'll find tons of games (I like JirboBreak, a free game inspired by the Atari classic Breakout) and mobile versions of popular websites like Pandora, Facebook, MySpace and the New York Times. Most apps will cost you, but the vast majority are $9.99 or less. The apps work on the old iPhones too, but you'll enjoy them a lot more on the iPhone 3G because many of the programs, including Yelp (local business reviews), Whrrl (mobile social networking) and UrbanSpoon (restaurant reviews), use your exact location - provided by the iPhone 3G's GPS chip - to make recommendations. The apps also load much faster over the 3G network.
57. The new iPhone 3G has following features except that _______
A. It looks and feels better
B. It has a faster network
C. It is easy to locate a place
D. It is too expensive for people to buy
58. Why do one of my colleagues carry Verizon phone with him all the time? ______.
A. Because iPhone 3G is just a toy
B. Because he prefers Verizon phone better.
C. Because AT&T's cellular coverage is terrible there
D. Because Verizon phone enables him make a phone call and surf the Web at the same time
59. Which of the following statements is NOT true according to the passage. ____.
A. App Store will offer you great fun.
B. many apps have been developed for the iPhone.
C. Most apps are very expensive.
D. Pandora, Facebook, MySpace and the New York Times are popular websites.
60. From the passage we know that the attitude of the author toward iPhone 3G is _____.
A. doubtful
B. appreciative
C. optimistic
D. pessimistic

书面表达
My dear classmates,
There is no denying that safety plays an important part in our daily life. Recently our school has carried out a program aimed at making our campus a safe place to stay on.
I consider this as indeed a good practice, which will make us aware that safety should always come first in our daily life, whether when we stay at school or outside it. When we are doing sports, we should attach importance to the safety and avoid being hurt. Furthermore, when we get into trouble with our classmates, we should remain calm and avoid any form of fighting, which may only bring suffering and pain to us mentally and physically.
As far as I’m concerned, I feel all the students and tea chers should work hard and creatively to keep the ―safety at school‖ activity in mind. Besides, we supposed to observe the law discipline where we are at any moment.
Thanks.

Earthquake safety is very important and there is more to it than just keeping buildings from falling down. So if your home is in an earthquake area, you should prepare carefully before the earthquake comes. First, make sure you buy a house which is earthquake safe. All pipes should be fixed to the wall and all walls should be especially thick and strong. You also have to make sure that there are bolts underneath your house. They are one of the most important ways of protecting a house. Make sure the building has no broken windows and is well repaired. Second, look at the objects in your house.
