    No one can change the weather. Nobody can control the weather. But if we read correctly the signs around us, we can tell what the more important changes in the weather will be. This way of telling what the weather will be like on the following day or two is called weather forecasting. For many centuries and in all countries, people have studied the weather and tried to make weather forecasting. Rings around the sun are a sign of coming rain. Many people feel in their bones the coming of wet weather, their joints(关节) hurt. Some birds fly high if fine weather is coming, but they fly near the ground if rainy or stormy weather is on the way. It is probably because the insects which they are hunting fly low. If you see a rainbow during rainy weather, this is a sign that the weather will become clear and fine. If the stars twinkle clearly at night, then fine weather will continue. If a fog appears in the morning just above a river, then the day will be warm. If the sunset is mostly red in color, then the following day will be fine. If a rainbow appears in the morning, rainy weather will probably come. Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting.

1.People’s joints ache ______.

A.is a sign of coming rain B.without any reason

C.because they are ill D.because of the insects

    As computers become all the more popular in China, Chinese people are increasingly relying on computer keyboards to input Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes(笔画)of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school(小学). And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.

All the students interviewed say they usually use a computer.

It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.

"When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I’m familiar with it."

"I'm not in the mood(状态) to write when faced with a pen and paper."

Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

Many educators think differently. Shi Liwei , the headmaster of a famous primary school in the capital said "Chinese characters enjoy both practical and aesthetic(审美的) value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them"

To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory(必修的)and in universities, some professors are asking students to hand in their homework and essays written by hand.

1.Which of the following can best serve as the title of the passage?

A.The Importance of Handwriting and Typing.

2.The students interviewed prefer to write using a computer mainly because______.

A.they are usually asked to e-mail their Homework and Essays

B.they can correct the mistakes they make quickly and conveniently

C.they find it not easy to remember how to write a character

D.computers have become a trend and fashion in China.

3.Which of the following statements is NOT TRUE of the advantages of handwriting?

A.Handwriting contains the writer's emotion.

B.The writer’s thinking and personality are shown in his or her handwriting,

C.Handwriting can impress people well and build one’s self-confidence

D.Chinese characters enjoy both practical and aesthetic value.

A.getting bored with B.getting dependent on

    On Saturday, millions of people around the world will celebrate Saint Patrick’s Day, which honors Patron Saint (or main religious figure) of Ireland. Communities across the United States will host parades (游行), parties, and other festivities to mark the occasion.

This year, cities like Boston, New York, and Chicago have organized massive (大规模的) events celebrating Saint Patrick's Day. In New York City, hundreds of thousands of people will gather to watch the Saint Patrick’s Day parade — the nation’s largest. It is one of the most watched parades in the world. Last year, almost 2 million spectators(观众) and more than 150,000 participants (参与者) filled the streets. The parade, first held in 1776, is also one of the oldest.

Chicago also throws a big celebration. Every year, the Chicago River, which crosses the city, glows (反光) green as event organizers dump about 40 pounds of fluorescence (荧光粉), a powerful dye (染料), into the water.

Boston keeps its parade rolling for three hours or more. It is the nation’s second-largest parade. The city will also salute (致敬) one of its most famous former residents (居民), President John F. Kennedy, by opening the exhibit “A Journey Home: John F. Kennedy and Ireland,” at his official library.

Patron Saint lived in Britain in the early fifth century, when it was still part of the Roman Empire (帝国). He was captured and sold into slavery (奴隶制) in Ireland when he was only 16. He eventually escaped slavery and turned to a life of religious devotion. He trained to become a minister (主教) and set out to spread Christianity throughout Ireland. After 30 years as a religious leader, Patrick died on March 17, 1461. Saint Patrick’s Day is always celebrated on March 17. In Ireland, it is an official holiday.
