Save the earth, save us!
Nowadays, our earth is suffering from serious environmental problems, such as water pollution, air pollution and noise pollution.
Smoke from factories and gases from vehicles are the main reasons for air pollution. Rivers are polluted when people throw waste into them, or when factories pour waste water into them. Modern lifestyle and modern ways of production also cause noise pollution. As a result, many species are dying out. More and more people are suffering from health problems.
The earth is the only planet where we can live. So enough attention should be paid to this problem and measures should be taken. Firstly, we should make laws to prevent factories from pouring waste water into rivers and sending smoke into the air without being dealt with. Secondly, we should raise people’s awareness of the serious problem and call on more people to protect the environment. Only by working together can we help the environment!
Gradually, fresh air is gone caused by smoke from factories and gases from vehicles; beautiful rivers are gone because of waste illegally thrown into them; quiet environment is gone because of noise pollution caused by modern ways of production and transportation.
Let’s save our planet and ourselves together! Firstly, we should make laws to prevent factories from pouring waste water into rivers and sending smoke into the air without being dealt with. Secondly, we should raise people’s awareness of environmental protection. Only by working together can we help the environment!
Love the earth means loving ourselves. Please take your part in environmental protection!

一、阅读理解
Flu is a common infection of the nose and throat，and sometimes the lungs. The cause is a virus that passes from one person to another. The virus spreads through the air when an infected person expels air suddenly.
Flu develops after the virus enters a person’s nose or mouth. The flu causes muscle pain，sudden high body temperature，breathing problems and weakness. Generally，most people feel better after a week or two. But the flu can kill. It is especially dangerous to the very young，the very old and those with weakened defenses against disease.
Medical experts have recognized for some time that people become infected with flu during the winter months. But they did not really know why until recently.
American researchers say they now know why the flu virus spreads in the winter and not in the summer. They say it is because the virus remains in the air longer when the air is cold and dry.
Researchers in New York carried out twenty experiments with guinea pigs to investigate how the virus spreads. The researchers found the virus spread the most when the temperature was about five degrees Celsius and the humidity was twenty percent. Few of the guinea pigs developed flu as the temperature increased. The virus stopped spreading completely at thirty degrees Celsius and eighty percent humidity. The researchers also found that the animals spread the virus among themselves nearly two days longer when the temperature was low.
One of the researchers said the study shows that flu virus is more likely to infect people during an outdoor walk on a cold day than in a warm room. He said cold air helps the virus survive in the air and low humidity helps it stay there longer. That is because particles of the virus ride on the extremely small drops of water floating in the air. When the air is very humid，water droplets fall to the ground more quickly.
The researchers say，however，that people should not stay in warm places all the time in cold weather to avoid the flu. They say the best way to prevent the sickness is to get yearly injections of a vaccine that prevents flu.
1. From the passage we can conclude that ________.
A. flu sometimes is deadly to weak people
B. flu virus can be killed by the warm weather
C. flu virus can be killed by the low humidity
D. animals get infected with flu easier than human beings
2. According to the passage，why is a person infected with the flu easily in winter?
A. Because in winter people tend to stay in the warm room.
B. Because in winter some people stay outdoor for long.
C. Because flu virus survive longer in cold and dry weather.
D. Because people are weaker in winter.
3. Which of the following words can replace the underlined word in the first paragraph?
A. Exposes. B. Breathes. C. Frees. D. Faces.
4. Which of the following will probably be discussed next?
A. How many kinds of flu have been identified.
B. How bird flu affected human being.
C. How the government controlled the flu.
D. How much the vaccine will cost.

The Mississippi
The Mississippi is a great river whose relationship with man goes way back beyond its discovery in the 16th century. The River Indians used it as a highway and as a source of food, and it was they who gave it its name — “misi” meaning “great” and “sipi” meaning “water”. When the length of its branch, the Missouri, is added to it, the Mississippi becomes greater. 1. _________. From the source of the Missouri to the tip of the delta (三角洲), it is 2,480 miles long.
Great rivers are likely to suffer floods. In 1927 the Mississippi flooded 26 thousand acres, sweeping away farms, towns, everything in its path. In 1938 its floods drowned or killed 200 people and made millions homeless. Today the river has largely been controlled. 2. _________.
Industries have spread down some of the waterways of the delta, but otherwise the delta is a remote place, the homeland of a little colony of French Canadians that the British drove out of Nova Scotia in the 18th century. They still speak French, mixed with English, Indian, Spanish and Negro idioms. They keep to themselves, fanning the rich soil of the delta. 3. _________
4. _________. Pioneers who first reached its banks wondered not only where it went, but what lay beyond. In 1764 the French founded a city on the right bank of the river, and named it after their king, Louis XV. This city, named St. Louis, became the jumping-off place for the adventurous men and women who opened up the Great Plains, and the way to the Far West.
Some 40 years earlier, at the beginning of the 18th century, the French had founded another city just above the Mississippi delta, New Orleans. 5. ______ New Orleans is one of the great ports of the world, and one of the greatest terminals for both sea and river traffic.
A. It was the Mississippi that made the city what it is
B. Levees, high banks built of earth, hold back the flood waters
C. Therefore, as we know, it’s the third longest river in the world
D. It is known that the “Great Water” has also been a frontier river
E. However, they paddled up and down the Mississippi in their boats to seek their fortune
F. The “Great Water” always remains a thread (分界线), for the streets of the city are below the level of the river
G. They call themselves Cajuns, who have actually been leading fairly primitive lives and preserving their own traditions
三、写作
假定你是李华，正在英国接受英语培训，住在一户英国人家里。今天你的房东Mrs Wilson 不在家，你准备外出，请给Mrs Wilson 写一留言条，内容包括：
1. 外出购物
2. 题房东还书
3. Tracy 来信留言：1）咖啡屋（Bolton Coffee）见面取消
2）此事已告知Susan
3）尽快回电
注意：
1. 词数100左右；
2. 可以适当增加细节，以使行文连贯。
一、阅读理解
1. A 解析：推理判断题。文章第二段提到：It is especially dangerous to the very young，the very old and those with weakened defenses against disease.所以对于身体比较弱的人来说，流感有时是致命的疾病。
2. C 解析：细节理解题。文章第四段提到：the virus remains in the air longer when the air is cold and dry.
3. B 解析：词义猜测题。从文意知病毒是通过空气传播的，故此处指当一个被感染的人突然呼气。所以用breathe。
4. A 解析：推理判断题。前面讲了流感是什么，有什么样的危害，在什么情况下最容易感染，并提出了解决办法。所以后面最可能说明目前知道的流感有哪几种。
二、阅读七选五
1. C 考查上下文联系。根据上句When the length of its branch, the Missouri, is added to it, the Mississippi becomes greater.加上它的支流—密苏里河的长度，密西西比河变得更壮观了。因此密西西比河成为世界上第三大长河。故选C项。
2. B考查上下文联系。根据上句Today the river has largely been controlled.现在密西西比河大部分已经得到控制，那么下句应该谈治理的手段。因此选B项。
3. G 考查上下文联系。第三段主要讲三角洲历史和居民。G选项的意思是：他们称自己为卡津人，保持着原始的生活方式和自己的传统。故选G项。
4. D 考查上下文联系。根据下文讲述的密西西比河的历史，可以推断第一句是本段的主题句或过渡句。句意：众所周知，The Great Water是一条边境河流。选D项。
5. A 考查上下文推断。根据上句the French had founded another city just above the Mississippi delta, New Orleans.法国人在密西西比三角洲上建立了另一个城市，新奥尔良市。可知，是密西西比河塑造了新奥尔良市现在的样子。故选A项。
三、写作
参考范文：
Mrs Wilson,
I’m going out shopping, and won’t be back until about 5:00 pm. I have taken with me the two books you asked me to return to the City Library. At about 1 o’clock this afternoon, Tracy called, saying that she couldn’t meet you at Bolton Coffee tomorrow morning as she has something important to attend to. She felt very sorry about that, but said that you could set some other time for the meeting. She wanted you to call her back as soon as you are home. She has already told Susan about this change.
