water is very important for living things. without water there can be no life on earth. all animals and plants need water. man also needs water.
water is found atmosteverywhere. even in the driest part of the world there is some water in the air.
as we all have found out, water may be a solid, or a liquid or a gas.when it isa solid, it may be as hard as brick, when itis a liquid, you can pour it out of a container. when it is a gas, you cannot see or feel it.
although about 70 percent of the earth's surface is covered with water,there are many places in the world still running out of water. so we should make good use of water on earth.
Most people would like to be popular with others,but not everyone canachieve this goal. What is the secret to popularity? In fact,it is very simple.The first step is to improve our appearance. We should always make sure that westay in good shape and dress well.

After all,ourfacial expression is an important part of our appearance. If we can do this,people will be attracted to our good looks and impressed by our confidence.
Another important step is developing more consideration for others. Weshould always put others first and place their interests before our own. It'salso important to be good listeners; in this way people will feel fortableenough to confide in us. However,no matter what we do,we must not gossip.

Good evening, ladies and gentlemen:
i’d like to start with a group of pictures.
"modern and advanced"? this society forgets, and ignores the other two thirds of human beings. it's far from the ideal! we call ideal as a utopian, a place where reality does not e_ist. a few people still look forward to the ideals. we make fun of them, considering they are naive. will we still be content to live in such a society, if misfortune drops to us? no! of cause not!
when we feel the warmth of the sun, these people, endure great sorrows and pains. can we imagine that? they are our brother and sisters!
facing them, will we still complain about our own misfortune?
facing them, will we still have the mood shouting for our own freedom? facing them, will we still want to have more and more unnecessary stuff?
they are unable to meet their needs, even the basic needs of survival! everyone, as a member of humanity, shouldn't feel ashamed? our lu_ury deprived their lives, our indifference violated our soul, and our barbarity destroyed human civilization!
what's the ideal society? it's a society no one worries about their living, a society no one is refused from education, a society everyone can pursue his/her own happiness! the ideal society is filled with love, joy and kindness. in that society, we can touch the other's hearts, we can share our dreams and most important, we can just be the true men!
let's break the ethnic divide, bridge the gap between rich and poor, hand in hand, to build a great wall, protecting us from evil; to construct a steady bridge, connecting reality to the ideal society! let's pursue for that, that's the only way to the bright future! they are watching us! thank you!

Lost time is never found again. This is something which I learned very clearly last semester. I spent so much time fooling around that my grades began to suffer. I finally realized that something had to be done. It was time for a change.
Now I have a new plan for using my time wisely. I have set my alarm clock ahead half an hour. This will give me a head start on the day. I have also decided to keep a log of what I do and when I do it. Looking back on what I’ve done will give me some ideas on how to reorganize my time.
失去的时间再也找不到。这是我上学期学的很清楚的东西。我花了这么多的时间在愚弄，我的成绩开始受到。我终于意识到必须要做的事情。这是一个改变的时候。

Saving WaterThe world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earth's surface is covered with water. But about 97% of this huge amount is sea water, or salt water.
Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us.
But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?We all have to learn how to stop wasting our precious water.
One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.
