Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive if the rain is spread throughout the year. If it falls, within one or two months and the rest of the year is dry, those plants may die and a desert may form.
Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.
There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs (悬崖) and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert, mountains are always changing—very, very slowly —as these forces of nature continue to
work on the rock.
Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.

Many people keep the stamps in a drawer at home because they’ll never know when they might need them! The trouble is that they have no idea of how many stamps they have left. When they want to send something by post, it’s very annoying to find out that they have run out of stamps!
The Internet is possible to solve the problem. The United States Postal Service has come up with a system which allows people to print their own postage stamps at their own home! This is the perfect solution for those people that have busy lives!
Whenever you go to the post office to buy a stamp, you are buying a boring and standard postage stamp. They are red in color, and you can easily buy them on the Internet as well. For example, you can just order a regular 1st class stamp and then print it off using your own printer (打印机).
These days, you can have much more fun with your stamps. You can buy them online instead of going to the post office. You can decorate, preview (预览) and print your stamps all at your own home. You are able to use any of your own photos as part of your postage stamp as well.
These stamps aren’t just allowed to be used in the United States; they can be used to send your mail throughout the world. They are perfect to use for many special occasions, such as weddings, festivals and even birthdays! They are fantastic!

No one is glad to hear that his body has to be cut open by a surgeon（外科医生） and part of it taken out． Today， however， we needn't worry about feeling pain during the operation． The sick person falls into a kind of sleep， and when he awakes， the operation is finished． But these happy conditions are fairly new． It is not many years since a man who had to have operation felt all its pain．
Long ago， operation had usually to be done while the sick man could feel everything． The sick man had to be held down on a table by force while the doctors did their best for him． He could feel all the pain if his leg or arm was being cut off， and his fearful cries filled the room and the hearts of those who watched．
Soon after 1770， Josept Priestley discovered a gas which is now called “laughing gas”．Laughing gas became known in America．Young men and women went to parties to try it． Most of them spent their time laughing，but one man at a party，Horace Wells，noticed that people didn't seem to feel pain when they were using this gas．He decided to make an experiment on himself．He asked a friend to help him．
Wells took some of the gas，and his friend pulled out one of Well’s teeth．Wells felt no pain at all．
As he didn't know enough about laughing gas， he gave a man less gas than he should have． The man cried out with pain when his tooth was being pulled out．
Wells tried again，but this time he gave too much of the gas，and the man died．Wells never forgot this terrible event．

When Christopher Columbus landed on the then unnamed Costa Rica in 1502, he saw many Indians wearing gold earrings. So he thought the land must be rich in gold. He named the place Costa Rica, which means “rich coast” in Spanish.
Though little gold was found, Costa Rica today is indeed rich with coffee and bananas. Coffee is the most important product in Costa Rica and most of it is exported (出口) to other countries like America and West Germany. Bananas are the country’s second most important export.
Costa Ricans also grow many other crops such as fruits, corn and beans for their own use. Costa Ricans love colors and their houses are painted in bright colors.
Education is very important to the Costa Ricans. Almost every village has a school and education is a must for children between seven and fourteen years of age. Boys and girls go to separate (单独的) schools. Classes begin in March and end in November. The other three months of the year are harvest time and the children have to help their parents to pick coffee beans.

Email has brought the art of letter writing back to life, but some experts think the resulting spread of bad English does more harm than good.
Email is a form of communication that is changing, for the worse, the way we write and use language, say some communication researchers. It is also changing the way we interact(交流) and build relationship. These are a few of the recently recognized features of email, say experts, which should cause individuals and organizations to rethink the way they use email.
“Email has increased the spread of careless writing habits,” says Naomi Baron, a professor of linguistics(语言学) at an American university. She says the poor spelling, grammar, punctuation and sentence structure of emails reflect(反映) a growing unconcern about the way we write.
Baron argues that we shouldn’t forgive and forget the poor writing often shown in email. “The more we use email and its tasteless writing, the more it becomes the normal way of writing,” the professor says.
Others say that despite its poor writing, email has finished what several generations of English teachers couldn’t: it has made writing fashionable again.
“Email is a critical new communication technology.” says Ian Lancashire, a professor of English at Toronto University. “It fills the gap between spoken language and the formal methods of writing that existed before email. It is the purest form of written speech.”
Lancashire says email has the mysterious ability to get people who are usually scared by writing to get their thoughts flowing easily onto a blank screen. He says this is because of email’s close similarity to speech. “It’s like a circle of four or five people around a campfire,” he says.
Still, he accepts that this new-found freedom to express themselves often gets people into trouble. Emails sent in a day almost exceed(超过) the number of letters mailed in a year. But more people are recognizing the content of a typical email message is not often exact.
From what Baron says in the third paragraph we can see that ________.

A．careless people use email more than careful people

B．email requires people to change their native language

C．professors in universities don’t need to use email

D．people communicate by email full of mistakes

What does the underlined word “it”(in Paragraph 4) refer to?

A．The poor writing.	B．Email.
C．The good writing.	D．A new communication technology.

In Lancashire’s opinion, email is a wonderful technology because _______.

A．it can be useful all over the world

B．it is the fastest way to communicate

C．we can express ourselves in a free way

D．we can save a lot of paper

This passage mainly shows us that ______.

A．people should stop using email to communicate

B．experts hold different opinions about email writing

C．Americans only use email to communicate

D．email makes people lose interest in English

A．a poster	B．science fiction
C．collection of choice stories	D．newspaper
