The water we drink and use is running short in the world.

We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.

Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring.

But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt.

This process is called desalinization, and it is already in use in many parts of the world.

The way to stop wasting our limited water is to （）.

A.do experiments with water

B.purify the used water and reuse it

C.use fresh water once again

D.make use of seawater

How men first learnt to invent words is unknown; in other words, the origin of langua

ge is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thought and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to present those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words. The power of words, then, lies in their associations - the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something increases. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and vulgar. What is true about words？

：A、They are used to express feelings only

B、They can not be written down

C、They are simply sounds

D、They are mysterious.

Which of your two hands do you use more？ Very few of us can use both hands equally well. M

ost of us are right-handed. Only about five people out of a hundred are left-handed. New-born babies can take hold of things with either of their hands, but. in about two years they usually use their right hands. Scientists have found that monkeys like to use one of their hands more than the other, but it can be either hand. There are as many right-handed monkeys as there are left-handed ones. Next time when you visit a zoo, you'll see that some of them will use their right hands and others will use their left hands. But most of the people use their right hands better and this makes life difficult for those left-handed people. We live in a right-handed world.

Most people ______.

A．are left-handed

B．are right-handed

C．can use both hands equally well

D．never use left hands

Passage TwoHow men first learned to invent words is unknown. All we really know is that me

Passage Two

How men first learned to invent words is unknown. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.

The power of words, then, lies in their associations--the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the happy and sad events of our past; the more we read and learn, the larger the number of words that mean something to us becomes.

Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and feelings. This attractive use of words is what we call literary style. Above all, the real poet is a master of words. He can express his meaning in words which sing like music, and, by their position and association, can move men to tears. We should therefore learn to choose our words carefully and use them correctly, or they will make our speech dull and silly.

Which of the following did men invent first？

A．Words.

B．Sounds.

C．Signs.

D．Letters.

s a mystery. All we really know is that men, unlike animals, invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other, and later they agreed on certain signs. These signs were called letters, which could be combined to represent those sounds and could be written down. Those sounds, whether spoken or written in letters, are called words.

The power of words, then, exists in their associations—the things they bring up before our minds. Words become filled with meaning for us by experience, and the longer we live, the more certain words remind us of the glad and sad events of our past, and the more we read and learn, the more number of words increases.

Great writers are those who not only have great thoughts but also express these thoughts in words which deeply attract our minds and emotions. This skillful use of words is called "literary style". Above all, a real poet can express his meaning in words which sing like music and can move men to tears. We should, therefore, learn to choose our words carefully and use them properly, or they will make our speech silly and vulgar.

The origin of language is______.

A．treasure handed down from the past

B．a matter that is hidden or secret

C．a problem not yet solved

D．a question difficult to answer
