70% of the earth"s surface is covered with water. But about 97% of that is sea water, or salt water. Man can
only drink and use the other 3%-fresh water from rivers, lakes, underground, and other sources (资源).
But we cannot even use all of that.
However, our need for water is becoming larger almost day by day. We should take steps (措施) to deal
with (对付; 处理) this problem now and in this way we can avoid (避免) a serious worldwide water shortage
later on.
We all have to learn how to stop wasting our valuable water. One of the first steps is to develop (开发;
发展) ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer
system (下水道). From there it returns to the sea or runs into underground places.
But even if (即使) every large city reused its water, we still would not have enough.
All we have to do, to make use of (利用) sea water in the world, is to remove (去除) the salt. But it is not
an easy thing.
B: we haven"t got enough fresh water.
C: only 70% of the earth"s surface is water.
D: more water is sent into sewer system.

the same problems might go onto the Internet and write about them in a blog (博客). In many ways, a diary
and a blog are almost the same. So, what makes a blog different from a diary?
1. Usually, a teenager treats her diary like a book full of secrets. Both diaries and blogs tell what
happened to the writer that day.
I have a little sister, and sometimes I go online to read her blog. She writes about things like waking up
early for swimming practice and not studying enough for her chemistry exam. 2. Then, after I
finished writing, I would hide my diary in a secret place because I was worried that my sister might read it!
Because a blog is such a public way of writing, it has both good and bad points. 3. If I am angry
with a friend during school and write something bad about her in my diary, she will never know. However,
if my sister writes something bad about a friend, that friend may read her blog and get angry. 4.
A blog has good points, of course. People choose to write in blogs because they know that their friends
will read what they write. If I am feeling sad one day and write in my diary, "Nobody cares about me", no
one will know about it. However, if my sister writes the same words in her blog, her best friends will
quickly reply and tell her how much they like her. Blogs help people stay in contact (联系) with their friends
and know what the people around them are doing.
If people are careful about what they write, blogs are a very good way to write about everyday life.
However, I still prefer my old diary!
| A. So we have to be very careful of what we write. B. When I was her age, I wrote about the same thing, but only in my diary. C. The biggest problem with a blog is that anyone can read what you write. D. The biggest difference is that a blog is much more public than a diary. | ||||||||||||||

| People are often killed while crossing the road. Most of these people are old people and children. Old people are often killed because they usually can not see or hear very well. Children are often killed because they are not careful. They have to look and listen before they cross the road. A car, truck or bus can not stop very quickly. If the vehicle (汽车) is going very fast, it will travel many meters before it stops. People don"t always understand this. They think a car can stop within a few meters. The faster a car is traveling, the longer it takes to stop. It is very difficult for a person to know how far a car is traveling. The only safe way to cross the road is to look both ways, right and left. Then if the road is clear, it is safe to cross. The right way to cross the road is to walk quickly. It is not safe to run. If people run across the road, they may fall down. | ||||||||||||||
| 1. Who are often killed while crossing? 2. Why are children killed when crossing the road? 3. Is it easy for a driver to stop his vehicle when he finds something wrong some meters in front of him? 4. What had you better do when you cross the road? 5. Even though the vehicle is going very fast, it can stop within a few meters, can"t it? | ||||||||||||||

| Recently I was walking in town when I saw a group of school students in uniform. I was shocked to see that the girls" skirts were very short and they were wearing a lot of make-up. The boys looked very untidy. Their shirts were dirty and some of them even had their shirtfronts open. I noticed too that some of the students had pierced ears and-noses, which I don" t think should be allowed at school. And the other day, I was riding on the subway when I saw some boys from a local school. I know they were from this school because they were wearing the same uniforms my children. Instead of sitting quietly, these boys were making a lot of noise, chewing gum in an ugly manner, and using bad language. All the other passengers were looking at them and wondering how it was possible for these boys not to have any self-respect (自尊). They were also giving their school a very bad image (形象), which is shameful (羞耻的). I am a mother of two teenagers at school and I am worried that my children also behave like this and I do not know about it. Do school students know what is allowed and what is not allowed when they are wearing their school uniform? I think the school should be stricter with the students. And I think all students should be taught how to be polite. | ||||||||||||||
