We do not know when man first began to use salt, but we do know that it has been used in many different ways throughout history. Historical evidence shows, for example, that people who lived over 3,000 years ago ate salted fish. Thousands of years ago in Egypt, salt was used to preserve (保存) the dead.

Stealing salt was considered a major crime (罪行) during some periods of history. In the eighteenth century, for example, if a person was caught stealing salt, he could be put in prison and his ears could be cut off.

In the Roman Empire, one of the most important roads was the one that carried salt from the salt mines to Rome. Guards were stationed along the route to protect against salt thieves, and they received their pay in salt, thus bringing the English word, salary. Any guard who fell asleep while on duty was thought to be “not worth his salt”, and as a result he would get a little less salt on his next payday. The expression, “not worth his salt”, is still used today in English.

In the modern world salt has many uses beyond the dining table. It is used in making glass and airplane parts, in the growing of crops, and in the killing of weeds (雜草). It is also used to make water soft, to melt (融化) ice on roads and highways, to make soap, and to fix colors in cloth.

Salt can be got in various ways besides being taken from mines underground. Salt water from the ocean, salt water lakes or small seas can be used to make salt. Yet, no matter where it comes from, salt will continue to play an important role in the lives of people everywhere.

1.According to the text, salt can be used in the following EXCEPT _____.

A．keeping dead bodies

B．punishing thieves

C．protecting crops

D．making industrial products

2.In the Roman Empire many people were employed as guards to _____.

A．protect the city of Rome

B．watch people carrying salt

C．prevent thieves from stealing salt

D．carry salt from the mines to Rome

3.The expression “not worth his salt” used today refers to the one who _____.

A．fails to do his work well

B．should not be paid in salt

C．doesn’t want to work at all

D．should use less salt

4.The main purpose of the text is to tell readers _____.

A．how salt was found and got

B．salt is important in people’s life

C．salt was difficult to get in the past

Animals are natural resources that people have wasted all through our history.

Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.

Why should people care? Because we need animals. And because once they are gone, there will never be any more.

Animals are more than beautiful or interesting or a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.

For example, when farmers killed large numbers of hawks(鷹), the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied(繁殖) quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.

Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.

1.Why do people kill animals?

A．They kill animals for something they need.

B．They kill animals to raise some money.

C．Animals destroy their natural resources.

D．Animals create many problems.

2. Animals are important to us mainly because ______.

A．they give us a source of food

B．they are beautiful and lovely

C．they keep the balance of nature

D．they give us a lot of pleasure

3. Which of the following is NOT true?

A．People care much about animals because they need them.

In my opinion, there is only one legitimate (合法的) handgun sport and that is aim practice. It is practiced at objects which are properly monitored and usually quite safe. Only certain handguns are true “sporting weapons”, seen as such by the sport’s lovers.

On the other hand, shooting at tin cans and other small objects in one’s backyard is not and should not be considered a serious sport. When uncontrolled, it can be a very dangerous practice.

Some opponents (反對者) of handgun control have stated that we are out to stop all hunting and that controlling the handgun would severely affect hunting. That is simply untrue. Handgun control would in no way limit the freedom of the true hunter. Few if any hunters consider the handgun an effective hunting weapon.

There are a few hunters who do hunt with handguns, but most states place restrictions (限制) on the type of guns that can be used in hunting, the reason is that killing of game should be done in as humane (人道的) a way as possible. Some small handguns are more likely to wound the animal rather than kill it at once. Only long guns, rifles and shotguns are effective arms of hunting.

People must understand that handguns and hunters are separate matters. Because most of the hunters use a rifle or shotgun, there is no reason why their search for game and sport should be affected by handgun control. Mixing the anti-hunting matter with the handgun matter confuses the killing of animals with killing of people.

1.In the writer’s opinion, people should use handguns only when           .

A. hunters shoot at animals         

B. they aim at a criminal

C. objects are under control  

D. objects are only small tin cans in the backyard

2.According to the writer, hunting is not affected by handgun control because          .

A. hunters can use knives rather than guns to hunt animals

B. state government encourages hunters to use other guns

C. nobody cares what weapons are used to kill animals

D. most hunters use rifles rather than handguns

3.This passage mainly talks about           .

A. the relation between hunting and handgun control

B. the importance of aim practice

C. how handgun control affects hunting

D. different types of guns used in hunting

In many countries today, laws protect wildlife. In India, the need for such protection was realized centuries ago.
