I’m Cathy Brown. I am now working for the Sunshine Travel Service in Changsha. I have just come back from Taiwan, the biggest island of China. It is in the Pacific Ocean(太平洋) to the east of Fujian.

Last week, I took a group of French holiday-makers for a week’s trip to Taiwan. We traveled all around the island. There are a lot of places of interest. My favorite is Sun Moon Lake. You may ask why people call it so. If you fly high up over the lake and look down from your plane, you will find the answer yourself. In the middle of this lake, there is a small island that is called Pearl Island because it looks like a pearl. On one side of Pearl Island the lake looks like a sun, and on the other side it looks like a moon. That is why people call it the Sun Moon Lake.

There are many mountains around this lake. One of the nearest is Mount Ali. We stayed there for three days. We also had a dancing party with Gaoshan people. On our first day there we went to the mountain and watched the sun going down slowly in the west. On our last day we got up early and saw the beautiful sunrise(日出).

Taiwan is a wonderful place which is known for beautiful scenery.

It’s the end of class. When the bell rings, students of Luohu Foreign Languages School in Shenzhen quickly take out their cell-phones. They want to log on (登录) to their microblogs (微博) to check the funny things that have happened in the last hour. Since last year, the trend (潮流) of microblogging has swept the country. Recent surveys show that most students in middle schools have a microblog, and some even update(更新) their blogs over five times per day.

“We learn many fresh and interesting things on microblogs and they have become popular topics in class,” said Liang Jianmin, 14, a student at Harbin No 3 Middle School. “If you do not know about them, you are out of the loop (被排挤在圈外).” It is also a great place for students to let out stress. “My parents always ask me to study hard, and encourage me before exams, but actually it adds pressure (压力),” said Zhang Yazhe, 15, a student in Luohu Foreign Languages School. “When I share these feelings on my microblog, I get many replies from friends in the same situation, which makes me feel better.” But parents are worried that microblogging could be a waste of time. Some misleading(误导性的) messages may even cause danger to kids, they said.

Shen Mingde, a professor at the China Education Association, suggests parents not worry too much as long as kids are not crazy about microblogging. Instead, it can become a window for parents to understand their children.

“If parents can read their children’s microblogs, they’ll know their thoughts, thus (因而) leading to better communication and solutions to problems,” he said. Micro blogging tips for kids

★1. Don’t microblog for more than one hour a day.

★2. Never microblog in class.

★3. Try to talk face to face with people instead of just microblogging.

★4. Be critical (批判性的). Don’t trust all the messages on a microblog.

1.Why do the students quickly take out their cellphones after class?

A. Because they want to phone their parents to tell them the funny things.

B. Because they want to listen to music.

C. Because they want to log on to their microblogs.

D. Because they want to surf the Internet to check the funny things.

2.Liang Jianmin thinks people are out of the loop if they do not know________.

A. the popular topics in class

B. the popular songs in class

C. fresh and interesting things on the Internet

D. many fresh and interesting things on TV

3.What does the underlined phrase "let out" mean in Chinese?

A. 释放 B. 泄露 C. 熄灭 D. 开脱

4.What does Shen Mingde think of microbiogging?

A. It could be a waste of time.

B. Some misleading messages may even cause danger to kids.

C. It can become a window for parents to understand their kids.

D.Parents should not worry too much if kids are crazy about microblogging.

5.Which statement is true according to the passage?

A. Kids should microblog for more than one hour a day.

B.Kids should try to talk face to face with people instead of just microblogging.

C. The trend of microblogging has swept the country since five years ago.

Spring Festival makes us fat. We visit our relatives and eat. We watch television and eat. We play video games and eat. By the end of the holidays we are fatter and less fit.

The easiest way to avoid getting fat is to eat le ss! There is just too much good food to eat. And much of that good food is not good for our health. Hamburgers, Kentucky Fried Chicken and French fries taste good but harm our health.

Most of these foods come from America. And Americans are worried about their children, too. 25% of American kids are overweight. They get less than 15 minutes of exercise a day, drink 2 litres of soft drinks, and spend 20% of their day watching TV and playing video games.

However, most American kids are very active and there are lots of opportunities for them to play sports. They play basketball, American football, soccer, baseball and ice hockey (冰上曲棍球). There are even “Little Leagues” for kids as young as 5 to play organized sports.

So what can you do in China to get fit instead of fat? Well, you can start doing simple things, like walking more. Get off the bus one stop before your school and walk the rest of the way. Swimming is also a great way to keep fit. Just look at Guo Jingjing! Or you can skip rope ( 跳绳) or play basketball with friends.

It doesn’t matter what you do as long as you do it. So, get up early, get active and get fit!

1.During Spring Festival, what do we mostly do? __________
