Hundreds of years ago, life was much harder than it is today, people did not have modern machines. There was no modern medicine, either.

Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and affects our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It affects every living thing in the world.

    Cars, planes and factories all pollute our air every day. Sometimes the pollution is so thick that it is like a quilt(被子) over a city. This kind of quilt is called smog.

Many countries are making new laws to fight pollution. Factories must now clean their water before it is thrown away; they mustn’t blow dirty smoke into the air.

We need to do many other things. We can put waste things in the dustbin and not throw them on the ground. We can go to work by bus or with our friends in the some car. If there are fewer people driving, there will be less pollution.

Laws are not enough. Every person must help to fight pollution.

Many teenagers feel that the most important people in their lives are their friends. They believe that their family members don’t know them as well as their friends do. In large families, it is quite often for brothers and sisters to fight with each other and then they go to their friends for some ideas.

It is very important for teenagers to have one good friend or a group of friends. Even when they are not with their friends, they usually spend a lot of time talking among themselves on the phone. This communication(交际) is very important in children’s growing up, because friends can talk about something, and these things are difficult to say to their family members.

PART FOUR WRITING

SECTION A

Directions: Read the following passage．Fill in the numbered blanks by using the information for the passage．

Write NO MORE THAN 3 WORDS for each answer．

The Chilean earthquake, measuring 8.8 – magnitude, which struck early Saturday morning, released 500 times the energy of the 7.0 – magnitude quake that hit Haiti (海地) last month, a geophysicist told CBS’ “The Early Show. ” Tsunami warnings were issued for much of the Pacific, including Hawaii, following the quake that struck near the Chilean coast.

"When the earthquake occurred, it moved the land and then it moved the water causing the tsunami," said U.S. Geological Survey geophysicist Jessica Sigala. "And the coastal areas of Chile have already noticed the wave heights up to about 7 feet."

Sigala said Hawaiians can expect to see the waves from this tsunami around 11:20 a.m. local time (about 4:20 p.m. ET). "So we have to wait and see how big the waves will be."

"It's not so much the height [of the wave] but it's the width, it's how long the duration, and then it's also the speed at which it's traveling," said co-anchor Kelly Cobiella "Correct me if I'm wrong, but these waves are traveling at the speed of a jetliner, about 500 miles per hour?"

"That's correct. It's a big block of water coming onto the land," Sigala said.

Chile has already experienced several aftershocks following the quake.

"Aftershocks are definitely a concern," said Sigala. "We always see aftershocks with a large quake and a shallow quake, which this one was. And as of right now, we've located about maybe 15 aftershocks and those are of the larger kind. I'm sure they felt much more than that.

"A shallow earthquake just means that it happened pretty close to the surface," said Sigala. "And because of that the energy is really close to the surface, where all the buildings and people are."

    50 deaths caused by aftershocks have been reported, according to the national emergency agency, adding the estimate casualties to 960.
