The world is not only hungry, but it is also thirsty for water. This may seem strange to you , since nearly 70% of the earth’s surface (表面）is covered with water . But about 97% of that is sea water, or salt water. Man can only drink and use the other 3% — the fresh water (淡水)from rivers , lakes , underground , and other sources . And we can not even use all of that. Even worse, some of it has been made dirty.

　　 However, as things stand today, this fresh water is still enough for us . But our need for water is becoming larger and larger quickly — almost day by day . We should take steps to do with this problem now and in this way we can get away from a serious world-wide water shortage（缺少）later on .

　   We all have to learn how to stop wasting our valuable water. One of the first steps is to develop ways of reusing  it .Today in most large cities , water is used only once and then sent out into a sewer system（下水道）. From there it returns to sea or runs into underground places.

　　 But even if every large city reused its water, we still would not have enough. All we’d have to do to make use of sea water in the world is to remove (去掉) the salt . If we take these steps we’ll be in no danger of drying up.

Many adults in the United States can remember crying the nursery rhyme in the street "Hot cross buns!" But only a few people realize this was an early form of advertising.
Written advertisements probably began with hieroglyphics more than three thousand years ago, but only a few people could read these symbols. So merchants made signs with pictures or hung their tools over their doors to identify their businesses.
In the time of the Roman Empire, wall paintings were a popular form of advertisement. An ad for a play, or some other performance was painted on part of a building or on a wall around a city. People often advertised a house for rent or a freshwater bath in this way, too.
Today, large wall signs are still used for outdoor advertising. But outdoor advertising is only a small fraction of the total advertising. About forty per -cent of all ads are printed in daily newspapers. Radio commercials also provide this kind of information. Some people think they are the best form of advertising because radio broadcasts reach almost everyone in a nation.
Advertisements in magazines and on television reach many people, too. However, usually only large companies can advertise on a national network, because TV commercials shown across the country can cost many thousands of dollars.
Then there are ads that are almost part of daily living. If you use public transportation, you will see large printed ads, called ear cards, on buses and taxis and in trains. Ads are painted on the trucks that deliver products people are buying or selling.
【小题1】Which is the passage mainly discussing?

Jungle country is not friendly to man, but it is possible to survive there. You must have the right equipment and you must know a few important things about woodcraft. Then your chances of staying alive are very good.

No one should go into the jungle without the right equipment. You need light weight clothing, a good knife, and a compass. Fishhooks and a line, a rifle, matches in a waterproof container and a poncho are necessary too. So is a mosquito net to protect the head.

In the jungle you can get hopeless lost within five minutes after leaving a known landmark. That is why you should always carry a compass. In open country, during the day, you can tell which way o go by studying the sun. At night the stars are sure guides o direction. But in most places the jungle rooftop is so thick that it is impossible to see the sun or the stars. Again and again you must check your position by the compass.

Keep alert. Watch the ground in front of you carefully. Stop and listen now and again. Avoid haste, and rest often. In a place that is hot and humid, the person who sets a fast pace will soon become tired. A steady, even pace is wisest in the long run.  

If you lose your way, don’t panic. Try to desire how long it has been since you were sure of your position. Mark the spot where you are with blazes on a tree. Put them on four sides of the tree, so that you will be able to see them from any direction. Then you can begin retracing your steps, knowing that you can always find the spot from which you started. Except in an emergency, never try to travel through the jungle at night.

Whenever possible, it is wise to follow streams and rivers that are going in your general direction. This may cause you many extra miles of travel. But in the end it will save time and energy. Nothing is more exhausting than hacking a trail cross-through umbrella jungle.

If a river is broad and deep and has no rapids, rafting is the best means of travel. Bamboo grows along the banks of many jungle streams. Since it is hollow and extremely strong, it makes a perfect raft.

Surviving in the jungle is a science. The jungle people have become perfect in this science, and you can too. Learn as much as you can about what to expect in the jungle. Make sure you have the right equipment. Then no part of the jungle will be able to “live off” it for a long time.

The author probably advises against traveling at night because ________.

one tends to move too slowly at night

some animals will attack you

emergencies occur most frequently at night

it is more difficult to check your position

Following streams and rivers will help you to ________.

avoid animal’s attacks

save many extra miles of travel

avoid crossing unbroken stretches of jungle

have a constant source of drinking water  

The word “blazes” in Paragraph 5 means _________.

A. marks where bark (树皮) is removed          B. light-colored spots

C.bursts of flame                            D. sides of knife

Even people who don’t understand English can enjoy Chaplin’s films because they are mostly silent. It isn’t what he says that makes us laugh. It depends upon actions which mean the same thing to people all over the world. He is master of the art – a kind of world language.
As a young man, he and his brother traveled to America in a small company of actors. Chaplin was then invited to join a new company that was making film comedies. Very soon he had made dozens of short films for this company. And it was in his second film that he wore the clothes which made his reputation – black hat, tight coat, baggy trousers, huge shoes, moustache and walking stick. He intended simply to make people laugh. But the odd make-up made him look both comic and sad.
By the time he was thirty, Chaplin was the greatest, best known and best loved comedian in the world. He received thousands of dollars for each film he made. He had formed his own manner of acting. He was welcomed by excited crowds wherever he went. But he worked very hard and had few close friends. Perhaps that is why the sad side of the little tramp began to show more clearly in the films he made. The little man began to want more than food and a roof over his head. He began to want love.
In one of his most famous films “The Gold Rush” a girl plays tricks on the little man. Then she begins to feel sorry for him and treats him kindly. He mistakes her pity for love. The girl in “City Lights” is blind. She thinks he is the most wonderful man she has ever met. But then she recovers her sight and sees what a foolish figure he is. This sadness gives Chaplin’s films a depth of human experience which few comedians can equal.
After living in America for forty years he moved to Switzerland. There he died on Christmas Day 1977. He once described himself as a citizen of famous pictures that were made during the 1920s and 1930s, the time of the silent films. But, to many people all over the world Chaplin will always be the king of comedy.
