A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃．Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate．Without the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world．
In the past hundred years，humans have begun destroying rainforests in search of three major resources(资源): land for crops，wood for paper and other products，land for raising farm animals．This action affects the environment as a whole．For example，a lot of carbon dioxide(二氧化碳) in the air comes from burning the rainforests．People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this．Firstly，when people cut down trees，generally they can only use the land for a year or two．Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply．
Rainforests are often called the world’s drug store．More than 25％ of the medicines we use today come from plants in rainforests．However，fewer than l％of rainforest plants have been examined for their medical value．It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests．Rainforests can help to adjust the climate because they ．

Why does most of the world travel on the right side today? Theories differ, but there’s no doubt that Napoleon was a major influence. The French had used the right since at least the late 18th century. Some say that before the French Revolution, noblemen drove their carriages on the left, forcing the peasants to the right. Regardless of the origin, Napoleon brought right-hand traffic to the nations he conquered, including Russia, Switzerland and Germany. Hitler, in turn, ordered right-hand traffic in Czechoslovakia and Austria in the 1930s. Nations that escaped right-hand control, like Great Britain, followed their left-hand tradition.
The U.S. has not always been a nation of right-hand rivers; earlier in its history, carriage and horse traffic traveled on the left, as it did in England. But by the late 1700s, people driving large wagons pulled by several pairs of horses began promoting a shift to the right. A driver would sit on the rear (后面的) left horse in order to wave his whip with his right hand; to see opposite traffic clearly, they traveled on the right.
One of the final moves to firmly standardize traffic directions in the U.S. occurred in the 20th century, when Henry Ford decided to mass-produce his cars with controls on the left (one reason, stated in 1908; the convenience for passengers exiting directly onto the edge, especially… if there is a lady to be considered). Once these rules were set, many countries eventually adjusted to the right-hand standard, including Canada in the 1920s, Sweden in 1967 and Burma in 1970. The U.K. and former colonies such as Australia and India are among the western world’s few remaining holdouts. Several Asian countries, including Japan, use the left as well — thought many places use both right-hand-drive and left-hand-drive cars.Why did people in Switzerland travel on the right?
| A．They had used the right-hand since the 18th century. |
| B．Rich people enjoyed driving their carriages on the right. |
| C．Napoleon introduced the right-hand traffic to this country. |

Henry Ford produced cars with controls on the left _______.

Given Australia’s size and the fact that early settlements were far apart, Australian society is remarkably homogeneous (同种的). Its citizens are fundamentally prosperous and the way of life in the major cities and towns is much the same however many miles divide them. It takes a sharp ear to identify regional accents. However, there is some difference in lifestyle between city dwellers and the country people. Almost 90 per cent of the population lives in the fast-paced cities along the coast and has little more than a passing familiarity with the desert. The major cities preserve pockets of colonial heritage, but the overall impression is modern, with new buildings reflecting the country’s youth. In contrast, the rural communities tend to be slow-moving and conservative. For many years, Australia was said to have “ridden on the sheep’s back”, a reference to wool being the country’s main money earner. However, the wool industry is no longer dominant. Much of Australia’s relatively sound economy is now achieved from natural coal and wheat, and by being the largest diamond producer in the world. Newer industries such as tourism and wine making are also increasingly important. Australians are generally friendly and relaxed, with a self-deprecating sense of humor. On the whole, Australia is a society without hierarchies (等级制度), an attitude generally held to stem from its prisoner beginnings.
Yet, contrary to widespread belief, very few Australians have true prisoner origins. Within only one generation of the arrival of the First Fleet in 1788, Australia had become a nation of immigrants. Originally coming almost entirely from the British Isles, today one in three Australians comes from elsewhere. Australia’s liberal postwar immigration policies led to an influx of survivors from war-torn Europe, most notably Greeks, Italians, Poles and Germans.
The emphasis has shifted in recent years and today the majority of new immigrants are from Southeast Asia. Today Australia is a ‘blend of nations’ and although some racism exists, it has generally been a successful experiment and the country is justifiably proud to have one of the most harmonious multicultural communities in the world.What does the writer mean by saying “It takes a sharp ear to identify regional accents.” in the first paragraph?

Sometimes people come into your life and you know at once that they were sure to be there. They serve some sort of purpose, teach you a lesson or help find out who you are or who you want to become. You never know who these people may be: your classmate, neighbor, teacher, long-lost friend or even a real stranger. But you know that every moment they will affect your life in some serious way.
Sometimes things happen to you. At the time they may seem terrible, painful and unfair. But later you realize that without getting over those difficulties you would have never realized your further ability and strength. Everything happens for a reason and nothing happens by chance or with good or bad luck.
The people you meet affect your life, and the successes and failure you experience, create who you are. Even the bad experiences can be learned from. In fact, they are probably the most poignant and important ones.
Enjoy every day even every moment and take from it everything that you possibly can, for you may never be able to experience it again. Talk to people you have never talked to before, and really listen. You should set your sights high, hold your head up, tell yourself you are a great one and believe in yourself.

You probably know you should say “ please” and “thank you ” at restaurants. You probably know the rules of a library. You know you should respect and be nice to your classmates. But do you have music manners?
Keep It Down! You have to notice the volumeof your music. You should not play your music so loud that everyone around you can hear it. Some people might even get angry. Usually, when you play the music loud on an MP3 player, other people can’t hear the words of the song. They just hear a loud sound. Not one wants to listen to this. Very loud music can also be bad for your ears, so even if you are alone when listening to our MP3 player, you shouldn’t have it turned up too high.
Take Them off! You need to know when to turn your MP3 player off and put it away. Libraries and schools don’t allow MP3 players. There are other places, like museums, that don’t have rules, but it would be rude to have your MP3 player on. Sometimes, it just doesn’t make sense to listen to your MP3 player at event. Why would you listen to music at a play, a movie or a sporting event? You would miss what is going on and others would wonder why you even came.
Take One Out! Once in a while it’s okay just to take out one earphone and not other. Imagine you are listening to your MP3 player when someone asks you the way. It would not be rude to take out one earphone, tell him the way, and put back the earphone and continue listening. You can also do this when you order food at a fast-food restaurant or when you answer the telephone and it’s not for you.
It’s Your Choice! There are times when you need to decide what is the best. For example, some people can listen to music on their MP3 Players when reading books, while others think it is disturbing. In cases like this, you need to do what seems right for you.The underlined word “volume” in Paragraph Two probably means.
A. the type of music
B. the amount of a sound
