For a long time, humans have used technology (科技) to study the world around us, and Mars is the latest place we’re using machines to explore. Besides the earth, the “red planet” is seen, as the one place in our solar system most likely to have life.
Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines’ safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet.
But the trips made by Spirit and Opportunity were dangerous. Mars is often called the “death planet”, because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them. It broke apart (分裂) near the earth.
小题1:For a long time humans think ________.
A.they can surely find life on Mars
B.there may be life on Mars
C.it’s too late for them to explore Mars now
D.Mars is the only planet that has life on it

A.have found out that it is warm and wet on Mars
B.were sent to Mars to find some stones

举一反三
阅读下列短文,根据短文中的信息完成文后表格。(每空一词)
In the past, man did not have to think about the protection of his environment. There were not many people on earth, and natural resources seemed to be unlimited.
Today, things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue like this, human life on earth will not survive.
Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste products are still put into rivers or into the sea, and there are few laws to stop this.
We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.
What can we do to solve these problems?
If we eat more vegetables and less meat, we will easily get more food. Land that is used to grow crops can feed five times more people than land where animals are kept.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems, we shall have a better and cleaner living place in the future.

The first bicycles were made of wood. After that, manufacturers used steel tubes. But the steel ones cost too much. The people in poorer countries want to have cheaper ones.

Izhar Gafni had an idea to make a cardboard bicycle able to support the weight of a human being. After three years hard work, he succeeded in creating this special bike. It is made of cardboard and 100% recycled materials. It costs less than $12.
The cardboard bike can hold a rider weighing up to 485 pounds. And if you don’t want to have it any more, you could just throw it into dustbin. And this will do no damage to the environment because it is easy to recycle.
When talking about his design, Izhar says, “It’s strong. It’s durable. It is cheap. What I like about it the most is: it’s made out of recycled cardboard.

Do you want to live a happier, less stressful life? Try laughing for no reason at all. That’s how thousands of people start their day at Laughter Clubs around the world.
The first Laughter Club was started in Mumbai, India, in 1995, by Dr Madan Kataria. “Children laugh about 300 times a day. Adults laugh between 7 and 15 times a day,” says Dr Kataria. “Everyone’s naturally good at laughing — it’s the universal (共同的) language.” There are now more than 500 Laughter Clubs in India and over 1,300 worldwide.
Many doctors are also interested in the effects (影响)of laughter on our health. According to a 5-year study at the UCLS School of Medicine in California, with laughing there is less stress in the body. Laughter improves our health against illness by about 40%.
So what happens at a Laughter Club? I went along to the nearest club in the south of London to find out. I was quite nervous at the beginning of the class. I had no interest in laughing with a group of strangers, and I was worried about looking stupid (愚蠢的). Our laughter teacher told us to clap our hands (拍手) and say “ho ho ho, ha ha ha” while looking at each other. Although we couldn’t tell the differences between fake laughter and real laughter, they still produced the same healthy effects.
Surprisingly, it worked! After ten minutes, everybody there was laughing for real and some people just couldn’t stop! At the end of the class I was shocked by how relaxed and comfortable I felt. So if you’re under stress, then start laughing.

It seems to be strange to you there is a blind spot(盲点)on the eyes,  Here is an interesting experiment(实验)that can make something disappear, when one eye is open.
Make a card about the size of a postcard and write two English letters L and R on it, Lon the left and R on the right. First, hold the card about 80 cm away and you see both the letters.  Then close your right eye and look at the letter R only with your left eye. And now, as you move the card slowly towards you, you" 11 find the letter L disappearing. But if you move the card nearer to your face, the letter will be seen again. Now do the same experiment with your left eye closed, you"ll find the letter R disappearing.
Why does the letter disappear? It is because there is a blind spot on the eye. When the image(影像)of the letter falls on the blind spot,  it won"t be seen.  That is why either of the letters disappears.

The world is not hungry , but it is thirsty . It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can"t drink or use for watering plants directly. Man can only drink and use the 3% - the water that comes from rivers and lakes. And we can"t even use all of that, because some of it has been polluted .
  Now more water is needed. The problem is: Can we avoid (避免) a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it . Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers . But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?
  The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it"s already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we"ll be in no danger of drying up.
