Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas.  

Most Americans would find it hard to imagine what life would look like without cars.  . The polluted air becomes poisonous and dangerous to health.

  . That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

Another way is to take the place of the car engine by something else.   . Many makers believe that it will take years to develop a practical model that pleases man.

To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down.  .

Although cars have led us to a better life, they have also brought us new problems.

A.Thus the problem of air pollution would become less important than that of unemployment.

B. Americans know cars very well.

C. However, some have realized the serious problems of the air pollution that is caused by cars.

D. One way to get rid of the polluted air is to build a car that does not pollute.

E. However, the number of vehicles has continued to increase in recent years.

F. Americans won’t live without cars!

G. Inventors are now working on steam cars as well as electric cars.

 Many different tribes live in the Ituri rain forest of Africa, but the Pygmies are the most unusual. Most of the men are not much more than four feet tall. They weigh only about eighty pounds. The women are even smaller and thinner. But in spite of the fact that they are small, these people are perfectly formed men and women.

      It is an exciting experience to visit a Pygmy encampment for the first time. Before you go, you must send word ahead that you are coming. Some friendly native or trader must take the message to the Tiki-Tikis. Otherwise the whole tribe will disappear into the depths of the jungle long before you have come close enough to be welcomed.

      The great Ituri rain forest seems cut off from the rest of the earth. There are living, dead, and dying trees on every side. Except where a clearing has been burned and chopped out, a man may live his whole life in the Ituri and never see farther than twenty yards.

      It takes sharp eyes to discover the almost hidden path to the Pygmy camp. The path is no wider than a small man’s foot. No sound breaks the silence in this part of the forest. There are no signs of people.

      The stranger must walk carefully. What appears to be a bent branch may prove to be a deadly snake. A spotted gold patch of sunlight may be a crouching leopard(豹).

Even the Pygmy camp comes as a surprise. The leafy shelters in which the little people live are hardly three feet high. They look so much like the surrounding undergrowth that they might easily be passed by. These houses contain no furniture of any sort. The beds are merely plantain leaves spread out on the earth floor. There are no cooking pots: food is eaten raw or smoked over a fire. Spears, bows and arrows are the only possessions of these people. When the tribe moves to a new camp there is nothing to carry except these weapons and babies too small to walk.

According to the passage, we can conclude _____.

    A. the Pygmies are the shortest tribe worldwide

    B. the Pygmies are short but normal in mentality

    C. most of the Pygmy men are more than four feet

    D. the Pygmies live in the forest of America

Paragraph 2 mainly suggests that the Pygmies ______.

    A. are unwilling to communicate with people outside

    B. are very cruel and they will kill you with the spears

    C. are friendly to the tourists visiting them for the first time

    D. move so fast and often that can’t be caught up with easily

Which of the following word can describe the life of Pygmy?

    A. Quiet.        B. Active.     C. Hard.        D. Busy.

Which of the following is TRUE of the Pygmy?

    A. Their houses can’t be easily found in the hurt rain forest.

    B. Their houses, which are three feet high, are made of wood.

    C. Weapons and cooking pots are their most valuable possessions.

D. They are living in harmony with dangerous animals around.

Researches show what we already suspected: Three out of four babies who died of SIDS(婴儿猝死) involved co-sleeping. We’ll say it again. The safest course is not to sleep with babies.

We know the argument: Bad parenting, not co-sleeping, is to blame for the dozens of babies’ deaths. Some parents stick to co-sleeping because it helps them bond with their newborns. They say those who give co-sleeping a bad name either had been drinking, used drugs or were too tired to notice that they rolled over on their children.

But, most of the cases did not involve drugs or alcohol. There’s a “but” here, however. Submitting to a test for drugs or alcohol in these cases is voluntary, so it’s difficult to know with certainty.

Organizations like the Black Health Coalition and others have explained the safe way to co-sleep. While we understand those arguments, we also know that mistakes can happen and that it only takes one time for something to go terribly wrong. The risk outweighs the benefit.

In all likelihood, parents will continue to co-sleep, and some will do so without ever having an incident, but babies are too vulnerable(易受伤的) for parents to take such chances. Therefore, the best place for babies to sleep is in their own beds, on their backs, with no pillows, blankets or toys. No parent wants a tragedy(悲剧) to occur. The best way to make sure the tragedy doesn’t happen is to allow babies to sleep alone in their own cribs(摇篮).                                         

According to the author, most of the SIDS cases happened because of ________.

A. drugs

B. co-sleeping

C. drinking

D. bad parenting

Some parents think sleeping with their babies can ________.

A. keep the babies healthy

B. give co-sleeping a good name

C. prevent themselves from drinking

D. develop a good relation with their babies

The author holds the opinion that ________.

A. parents can sleep with babies, but cautiously

B. co-sleep helps to bring babies closer to parents

C. parents can’t take chances to sleep with their babies

D. accidents only happen to those careless parents
