In the 13th century, the famous Italian traveler, Marco Polo, traveled a long way to China. During his stay in China, he saw many wonderful things. One of the things he discovered was that the Chinese used paper money. In western countries, people didn’t use the paper money until 15th century. However, people in China began to use paper money in the 7th century.
A Chinese man called Cai Lun invented paper almost 2,000 years ago. He took the wood from trees and made it into paper. He then put these pieces of paper together and made them into a book.
Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting nearly 48,000 trees every day. Since it takes more than 10 years for a tree to grow, we must start using less paper now.
So how can we save paper? We can use both sides of every piece of paper, especially when we are making notes. We can use cotton handkerchiefs and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant gives us a paper bag, we can save it and reuse it later.
Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.

Can you understand the beginning of this essay?
“My smmr hols wr CWOTT. B4, we usd 2go2 NY 2C my bro, his GF & 3 kds FTF.”
The Scottish teacher who received it in class had no idea what the girl who wrote it meant. The essay was written in a form of English used in cell phone text messages. Text messages (also called SMS2) through cell phones became very popular in the late 1990s. At first, mobile phone companies thought that text messaging would be a good way to send messages to customers, but customers quickly began to use the text messaging service to send messages to each other. Teenagers in particular enjoyed using text messaging, and they began to create a new language for messages called texting.
A text message is limited to 160 characters, including letters, spaces, and numbers, so messages must be kept short. In addition, typing on the small keypad of a cell phone is difficult, so it’s common to make words shorter. In texting, a single letter or number can represent a word, like “r” for “are,”“u” for “you,” and “2” for “to.” Several letters can also represent a phrase, like “l(fā)ol” for “l(fā)aughing out loud.” Another characteristic of texting is the leaving out of letters in a word, like spelling “please” as “pls.”
Some parents and teachers worry that texting will make children bad spellers and bad writers. The student who wrote the essay at the top of this page said writing that way was more comfortable for her. (The essay said, “My summer holidays were a complete waste of time. Before, we used to go to New York to see my brother, his girlfriend, and their three kids face to face.”)
Not everyone agrees that texting is a bad thing. Some experts say languages always evolve, and this is just another way for English to change. Other people believe texting will disappear soon. New technology for voice messages may soon make text messages a thing of the past.
小題1:What is the writer’s opinion of text messaging?
A．It is fun and easy to do.
B．It is not bad for children.
C．It will make children bad writers.
D．The writer does not give an opinion.
小題2:Which characteristic of texting is NOT described in the passage?
A．Using phrases to represent essays
B．Using numbers to represent words
C．Using letters to represent phrases
D．Using letters to represent words
小題3:Which of the following was most probably the title of the student’s essay?
A．My Gr8 TchrB．CU in LAC．My GFD．My Smmr Hols
小題4:   Why do some people think that texting is bad?
A．It costs too much.B．It’s too difficult to type.
C．Children won’t learn to write correctly.D．It’s not comfortable.
小題5:Why aren’t some people worried about the effect of texting?
A．Not many people use texting.
B．Spelling in English is too difficult.
C．Children quickly become bored with texting.
D．Texting will disappear because of new technology.

Plastics are considered one of the most serious pollutants causing environmental problems. The garbage containing plastics end up in the waterways that eventually flow into the oceans. Accumulation (聚集)of plastic in the ocean endangers marine life and pollutes the water.
Does a plastic continent exist? Yes, a plastic continent does exist and was discovered by Captain Charles Moore a decade ago. The plastic continent is twice the size of Britain and it is the region between the Hawaii Islands and California in the central Pacific Ocean.
One of the causes of the lack of marine life in this region is due to pollution and pollutants are none other than plastics. Captain Charles Moore believes plastic waste started accumulating in the 1950s.
The plastic continent is the man-made continent of floating plastic waste. The fisher men and the sailors have avoided this region for years. The reasons are:
1. There are no fish here because of the lack of nutrients.
2. The zone also lacks the wind that is essential for sailing.
To do research on the ocean pollution, Captain Moore founded Algalita Marine Research Foundation. Other organizations such as Greenpeace supported his cause. The reports of The United Nations Environment Program show that millions of seabirds and marine animals are dying due to the invasion(入侵)of plastics. The waste plastics can be recycled, but in fact they are being thrown into the oceans. The marine animals mistake these for food and eat them. This leads to their death that affects the marine food chain.
To save the oceans from the plastic continent you need to reduce the use of plastics, reuse plastic bags and recycle plastics.
小題1: What can we learn from the first paragraph?
A．A plastic continent does exist in the Pacific Ocean
B．Endangered marine life is well protected.
C．Plastics are one of the main causes of water pollution.
D．Plastics should be forbidden in people’s daily life.
小題2: What is the direct influence of the plastic continent?
A．Local fishermen have to fish in other areas.
B．The water becomes shallow and fish have to move away.
C．The wind is too strong there and it makes sailing more difficult.
D．It makes people realize the importance of protecting the environment.
小題3: It is implied that the work of plastic recycling proves to be ______.
A．effectiveB．expensiveC．a(chǎn) difficult taskD．not good enough
小題4:What can we learn from the passage?
A．Many marine animals are dying due to the broken marine food chain.
B．Captain Moore founded Greenpeace to do research on the ocean pollution.
C．The marine animals have no choice but to eat plastics for lack of food.
D．There are three ways to prevent the oceans from becoming a plastic continent.

What do you know about the sea? You may have seen it. Some of us have swum or bathed in it. It looks beautiful on a fine sunny day and it can be very rough when there is a strong wind. What other things do we know about it? Of course, the sea is very large. In the world there is more sea than land. The sea covers three quarters of the earth. The sea is also very deep in some places. It is not deep everywhere, some parts of it are very great. At one spot, near Japan the sea is nearly 11 kilometers deep! Just think of it, the highest mountain in the world is only about 9 kilometers high! If you have swum in the sea, you know that the water is salty. Rivers carry salt from the land into the sea. Some parts of the sea are more salty than other parts. Do you know the Dead Sea in Arabia? It is very salty. Swimmers cannot sink in it! Fish cannot live in the Dead Sea. It is a strange sea. In most parts of the sea, there are a lot of fishes and plants. Some live near the top of the sea. Others live deep down. No sunlight can reach the depth of the sea. So it is completely dark. Strange fishes live there. Some are blind. Some have their own lights. Some have great jaws. With their great jaws, they swallow fish larger than themselves. The sea can be very cold. Deep sea divers know this well. At the top of the water may be warm. Then as the divers go down, the sea becomes colder and colder.
Many scientists are now making a study of animal and plant life in the sea. They hope to find new resources for mankind.
小題1:. Which of the following statements is NOT true?
A．Land covers one fourth of the area of the earth.
B．The depths of the sea are different in different places.
C．The depth of a sea at one spot near Japan is nearly the height of the highest mountain.
D．The salt in the sea mainly comes from the land.
小題2:.. The Dead Sea is lifeless because ___.
A．the water in it is too coldB．the water in it is too salty for anything to grow
C．the water in it never flowsD．no sunlight can reach the bottom of the lake
小題3:. We can see the underlined word “rough” in this passage means ___.
A．uglyB．noisyC．coldD．not calm
小題4:.. Which of the following statements is true?
A．Some of the fish living in the depth of the sea can not see by themselves.
B．Some fish give out light for themselves.
C．Some fish live on other fish.D．All of the above
小題5:.. What does the writer intend to tell us in the last paragraph?
A．The necessity of the study of the sea.B．The purpose of man’s further study of the sea.
C．Man’s limited knowledge of the sea.D．The importance of new resources for man.

As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic (治療的) stem cells.
In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(細(xì)胞核) has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly ‘reprogrammed’.
Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos(晶胚) might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized(已受精的) fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics.
小題1:The best title of this passage probably is _______.
A．The importance of clone
B．First insects are cloned
C．The disagreement in clone
D．The advantages of clone
小題2:The scientists cloned flies because________.
A．there are fewer and fewer flies in the world
B．flies are easy to find and cheap to use
C．they can gain some experience before cloning other animals
D．it is safe to clone flies
小題3:The failure of most cloned animals is due to _______.
A．the difference of other animals’ genes
B．the improper technique of clone
C．the complex of other animals
D．the improper rearrange of the adult gene
小題4:It can be inferred from the last paragraph that ______.
A．the clone of insects before used grown-up cells
B．the clone of insects were never experimented before
C．this time scientists cloned flies successfully and easily
D．based on this success, other animals will be cloned in large quantities.

With alarming regularity, we read about oil tankers having accidents near land and the terrible consequences of the oil spills（泄露） on people, nature, and the environment．
Millions of dollars have been used in developing special chemicals to help dismiss the spills and to clean up the animals, beaches, and land spoiled by the oil．Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea．
Of all of today’s environmental disasters, an oil spill may actually be one of the least serious．Although oil is poisonous, it is a natural material．In the end, it breaks down naturally．There are, of course, long-term effects, but it is usually more serious in the short term．
Nature by itself works better than chemical materials, but when there is a spill we demand that governments act immediately with as much hi-tech knowledge as possible．In 1967 the tanker Torrey Canyon sank off the Sicily Isles near the coast of England and spilled 120,000 tones of oil into the ocean．If you go there today, you will find it hard to see any sign that it ever happened．
Governments seem to accept the risk of transporting millions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage．Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run!
We should be thinking more about reducing our dependency on oil．Governments should be encouraging research into new technologies, such as cars run by solar power（太陽(yáng)能）, electricity, hydrogen, and so on．Much of this research has, in the past, been held back by the oil, gas, and coal．
If the world’s millions of cars were 10% more efficient（高效的）— and the industry could easily produce cars at least twice as efficient — we would need many fewer tankers crossing the oceans each year．If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too．
小題1:What is the passage mainly talking about?
A．Oil tanker accidents．B．Oil spills pollution．
C．What oil pollution is．D．How to reduce oil pollution．
小題2:How does the author support the idea that oil spills are not as serious as people believe?
A．By giving a description．B．By making an argument．
C．By giving an example．D．By drawing a diagram．
小題3:What does the underlined word “risk” in Paragraph 5 refer to?
A．Transportation depending more on oil．
B．Poisonous oil breaking down naturally．
C．Millions of tons of oil spilling into the sea．
D．More environmental damage being caused．
小題4:Which suggestion is made for reducing oil tank accidents according to the passage?
A．We should develop new technologies to cut oil use
B．Tankers should not be allowed to sail near the coastlines．
C．We should build safer oil tankers in the near future．
D．Countries should build more oil pipelines under the sea．

When my grandmother was raising me in Stamps, Arkansas, she had a particular routine（慣例）when people who were known to be whiners entered her store. My grandmother would ask the customer, “How are you doing today, Thomas?”
The person would reply, “Not so good today, Henderson. You see, it’s this summer heat. I just hate it. It just makes me tired. It’s almost killing me.’ Then my grandmother would stand calmly, her arms folded, and say, “Uh-huh, uh-huh.”
As soon as the complainer was out of the store, my grandmother would call me to stand in front of her. Then she would say the same thing she had said at least a thousand times, it seemed to me. “Jane, did you hear what so-and-so complained about?” And I would nod. Grandmother would continue, “Jane, there are people who went to sleep all over the world last night, poor and rich and black and white, but they will never wake again. Those dead people would give anything, anything at all for just five minutes of this weather that person was complaining about. So you watch yourself about complaining, Jane. What you’re supposed to do when you don’t like a thing is change it. If you can’t change it, change the way you think about it. Don’t complain.”
I have learned a lot from my grandmother. Her opinions always hit the nail on the head. Whining is not only impolite, but can be dangerous.
