How to keep safe£¿

As teenagers, we should always keep safety in mind. But how can we keep safe? Here are some of my suggestions.

First, we should be careful when we make friends online. Second, on the road, we should pay attention to traffic safety. Also, we ought to eat healthily and safely. Eating food that goes bad will do harm to our health. Besides, summer is coming, we must remember it's dangerous to swim in the river.

In short, safety must come first!

¡¾ÌâÄ¿¡¿ There was once a very wide tree in South Africa. 60 people could stand in its hollow trunk(¿ÕÐÄÊ÷¸É). The tree reached over 18 meters into the sky and it was more than 1, 100 years old. But recently, that tree and others like it have died.¡¾1¡¿

The tree was a baobab(ºïÃæ°üÊ÷). Baobab trees grow in Africa and are called"the Tree of Life¡±.

Baobab trees usually live a long time. One of the oldest stood for more than 2, 400 years.

¡¾2¡¿They noticed that nine of the thirteen oldest baobab trees and five of the six largest died in the following 12 years.

Stephan Woodborne, one of the six scientists, says more research(Ñо¿)is needed to know why the trees died.¡¾3¡¿That's because the trees clearly weren't sick. Besides, many were in national parks, so they were protected from human activities. They believe that increasing temperatures and changing rainy seasons have made it harder for baobabs to live.

"The big ones and the old ones caught the attention of people, Woodborne says. "But it's not just those. ¡¾4¡¿People should be more environment-friendly. It is one way to help protect baobabs and other trees from the effects of climate change, according to Woodborne. ¡¾5¡¿

¡°We need to think about the way we live our lives. "Woodborne says. "If we all change what we do a little bit, it will start to make a difference.¡±

A.That could mean using less energy(ÄÜÔ´) and making less waste(·ÏÁÏ), when possible.

B.Smaller and younger baobabs are dying too.

C.However, they think climate change may be the main reason.

D.Scientists are wondering why.

E.In 2005, scientists began a research to find out the age of more than 60 baobabs.

brave say use at sound from also good ask interest

I often hear some students¡¾1¡¿English is difficult, and it gives them a headache. So they can¡¯t learn it ¡¾2¡¿. But English is very easy for me. I¡¯m good at it. I'm very glad to tell you something about how I study English.

First, I think an¡¾3¡¿in English is very important. When I was in Grade One, we had a new subject-English. It was fresh for me. I was interested in it. So I worked hard¡¾4¡¿it. Soon we had an English exam and I got a very good mark.

How happy I was! After that, I learned English harder and harder. Our English teacher often teaches us English songs. The songs ¡¾5¡¿nice. I often think how interesting English is!

Second, I think English is a foreign language. I should learn it well in the following ways: Listen to the teacher carefully, speak ¡¾6¡¿, read aloud and have a good vocabulary(´Ê»ã). Then practice again and again, and never be tired. And I ¡¾7¡¿ have a good habit: whenever(²»ÂÛºÎʱ)I have a question, I must make it clear by ¡¾8¡¿our English teacher.

What¡¯s more, I often read English stories, jokes and easy novels. From these I know English is not only interesting, but also¡¾9¡¿. They help me understand a lot of things. So to do more reading is an important way to learn English well.

I also do some exercises and I often write English diaries. English has become a close friend of mine. Now I have learned English for more than two years. I always keep the first position in my class. ¡¾10¡¿these words, I hope every student can learn English well.
