     In recent years many countries have been faced with the problem of how to make their workers more
productive. Some experts believe that the answer is to make jobs more varied. Do more varied jobs lead
to greater productivity? There is something to suggest that while variety certainly makes the worker"s life
more enjoyable, it does not make him work harder. So variety is not important.
     Other experts feel that giving the worker freedom to do his job in his own way is important and there
is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern
factory with its complicated machinery which must be used in a fixed way. Thus while freedom of choice
may be important, there is very little that can be done to achieve this.
     Another important consideration is how much each worker contributes to the product he is making. In
most factories the worker sees only one small part of the product. Some car factories are said to be
experimenting with having many small production lines rather than a large one, so that each worker
contributes more to the production of the cars on his line. It would seem then that the degree of workers"
contribution is important.
     To what extent does more money lead to greater productivity? The workers themselves cartainly think
this is important, but perhaps they want more money only because the work they do is so boring. Money
just lets them enjoy their spare time more. A similar argument may explain demands for shorter working
hours. Perhaps if companies succeed in making workers" jobs more interesting, they will neither want
more money, nor will shorter working hours be so important to them.1. Which of the following things will not increase productivity?A. Making jobs more varied.
B. Giving workers freedom to do their jobs in their own way.
C. Increasing workers" contribution to production.
D. Longer working hours.2. The last sentence in this passage means that if companies manage to make workers"jobs more
interesting, ________.A. they will want more money
B. they will demand shorter working hours
C. more money and shorter working hours are important
D. more money and shorter working hours will not be so important to them3. In this passage, the writer tells us________.A. how to make workers more productive
B. possible factors leading to greater productivity
C. more money leads to greater productivity
D. how to make workers" jobs more interesting

    The zebra belongs to the horse family.One of nature"s great mysteries is why the zebra has stripes.One
theory is that the stripes help the zebra cool down.On hot days the black stripes get a lot hotter than the
white area of the zebra and under the black stripes there are special layers of fat for protection.Hot air then rises off the black stripes,forcing colder air down around the white areas,cooling the zebra down.This,
however,is just a theory.The stripes can also confuse predators (食肉动物) when zebras stay with other
animals in great numbers.
     Zebras have excellent hearing and eyesight and can run at a speed of up to 35 miles per hour (56
kilometers per hour).They also have a powerful kick that can cause serious injury to a predator,like a
lion,or an African wild dog.Usually the lead male of the herd stays at the back of the group to defend
against predators if necessary,while the females and youngsters run from danger.
     Zebras are herbivores and feed mostly on grasses,although they also might eat the leaves and stems (茎) of bushes a bit.They eat grasses for many hours each day,using their strong teeth.Spending so much
time chewing wears the zebra"s teeth down,so their teeth keep growing all their lives.As the dry season
arrives and the grasses die back,zebra herds travel to find more food and water holes for drinking.Most
zebras have no specific territories.They travel from place to place,never staying in one area very long.1. What can be inferred from the first paragraph?A. There are different opinions about why the zebra has stripes.
B. The black stripes help the zebra live through cold days.
C. The zebra can easily be attacked by predators.
D. The zebra always travels with other animals.2. According to the passage,herbivores are________.A. animals that have specific territories
B. animals that only eat plants
C. animals that kill and eat other animals
D. animals that live in groups3. The zebra has strong teeth all their lives because their teeth________.A. only chew soft grasses
B. are used all day
C. are always growing
D. are kept clean4. Which of the following statements about zebras is TRUE?A. They have poor eyesight and hearing.
B. Their stripes can confuse predators.
C. They can run 56 miles per hour.
D. They usually stay in one area all their lives.5. Which of the following TV programs might the passage be adapted for?A. Hobbies & Leisure    
B. Everyday Tips
C. Digital Stadium      
D. Discoveries

阅读理解      Age plays a major part in people who are infected with cold,ie,in people who suffer from cold
infection.A study done by University of Michigan,has shown information that seems to be true for the
general population.Babies are the most cold infected group,generally more than six colds in their first year.Boys have more colds than girls up to the age of three.After three,girls are easier to get infected with cold
than boys,and teenage girls get three colds a year to boys" two.The general cold infections continue to get
less into adults.Elderly people who are in good health have as few as one or two colds every year.One
interesting thing is found among people in their twenties,especially women,who show a rise in cold
infection,because people in this age group are most likely to have young children.
      The study has also found that economy plays an important role as well.With more and more income,
the frequency at which colds are reported in the family is getting lower and lower.Families with the lowest
income usually suffer about a third ally forces people to live in rooms more crowded than rooms owned by richer people,and the crowding usually leads to more chances for the cold virus to travel from person to
person.Low income may also have an effect on our diet.Many scientists believe that a poorer diet usually
leads into more possibilities of cold infection.

1.Which of the age groups has the highest frequency of cold infection?              

A.Small babies.  
B.Teenage boys.
C.Adult women. 
D.Elderly people.

2.The purpose of writing this passage is to________.

A.give the readers some tips to avoid cold infection
B.show a carefullmade study on cold infection
C.report the major reasons leading to cold infection
D.describe all the possible dangers of cold infection

3.How does economy play an important role in cold infection?

A.Families with lower income suffer less from cold infection.
B.People who have lower income enjoy living in crowded rooms.
C.Rich families can have better nutrition and never get infected.
D.People with higher income have fewer chances of infection.

4.From the passage we can infer that________.

A.age is the only important factor that connects with colds
B.families with the highest income will more easily get infected
C.people have lower frequency of infection as they grow older
D.a better diet may help people to fight against cold infection

      Children start out as natural scientists, eager to look into the world around them. Helping them enjoy
science can be easy; there"s no need for a lot of scientific terms or expensive lab equipment. You only
have to share your children"s curiosity. Firstly, listen to their questions. I once visited a classroom of
seven-year-olds to talk about science as a job. The children asked me "textbook questions" about
schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in
silence. Finally I said, "Now that we"ve finished with your lists, do you have questions of your own about
science?"?
     After a long pause, a boy raised his hand, "Have you ever seen a grasshopper (蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?"?
     This began a set of questions that lasted nearly two hours. ?
      Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a
question, adults typically wait only one second or less for an answer, no time for a child to think. When
adults increase their "wait time" to three seconds or more, children give more logical, complete and
creative answers.
      Thirdly, watch your language. Once you have a child involved in a science discussion, don"t jump in
with "That"s right" or "Very good". These words work well when it comes to encouraging good behavior.
     But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying, "That"s interesting" or "I"d never thought of it that way before", or coming up with more 
questions or ideas.?
      Never push a child to "Think". It doesn"t make sense, children are always thinking, without your
telling them to. What"s more, this can turn a conversation into a performance. The child will try to find
the answer you want, in as few words as possible, so that he will be a smaller target for your
disagreement.?
     Lastly, show; don"t tell. Real-life impressions of nature are far more impressive than any lesson
children can learn from a book or a television program. Let children look at their fingertips through a
magnifying glass(放大镜), and they"ll understand why you want them to wash before dinner. Rather than saying that water evaporates (蒸发), set a pot of water to boil and let them watch the water level drop.

1. According to the passage, children are natural scientists, and to raise their interest, the most
    important  thing for adults to do is _______.

A. to share the children"s curiosity
B. to let them see the world around?
C. to explain difficult phrases about science
D. to supply the children with lab equipment?

2. In the last sentence of the first paragraph, the word "lists" could best be replaced by _______.

A. any questions       
B. questions from textbooks?
C. any problems  
D. any number of questions?

3. According to the passage, children can answer questions in a more logical, complete and creative
   way if adults _______.

A. wait at least for three seconds after a question.  
B. wait for one or two seconds after a question.?
C. tell them to answer the next day.
D. ask them to answer quickly.

4. The author mentions all of the following techniques for adults to share with their children"s curiosity
    except that adults should _______.

A. encourage their children to ask questions of their own?
B. offer their children chances to see things for themselves?
C. be patient enough when their children answer questions?
D. tell their children stories instead of reciting facts?
