Bats are the only mammals(哺乳动物) which can fly properly. Other flying mammals have wings of thin skin which cover their sides between their front and back legs. They can only fly from tree to tree, but they cannot change direction when they want to.

All bats fly at night and most of them hunt for flying insects(昆虫), such as bees. The common bat finds its food by making a constant noise that the human ear cannot hear. The bat listens for echoes(回声) of the noise as it bounces(反射) off the insects showing the bat their position.

The Fruit bat feeds on many different kinds of fruit. It does not use echoes but instead has very large, special eyes to see even in low light. The largest Fruit bat has a wing length of 0.75 meters. The Vampire bat drinks the blood of large mammals, and a few bats catch fish, birds and even other bats.

Some flying mammals are not real flyers because _____.

 A. they do not have wings                     B. their wings are too thin

C. they have skin between their legs             D. they cannot turn around in the air

When common bats hunt for food they _____.

   A. use echoes to kill the insects           B. make a noise to draw insects to them

C. produce a sound and listen to the echoes     D. listen noise made by the insects

    It seems that some people go out of their way to get into trouble. That’s more or less what happened the night that Nashville Police Officer Floyd Hyde was on duty.

    “I was on the way to a personal-injury accident in West Nashville. As I got onto Highway 40, blue lights and sirens(警笛)going, I fell in behind a gold Pontiac Firebird that suddenly seemed to take off quickly down the highway. The driver somehow panicked at the sight of me. He was going more than a hundred miles an hour and began passing cars on the shoulder.”

    But Hyde couldn’t go after him. Taking care of injured people is always more important than worrying about speeders, so the officer had to stay on his way to the accident. But he did try to keep the Firebird in sight as he drove, hoping another nearby unit would be able to step in and stop the speeding car. As it turned out, keeping the Firebird in sight was not that difficult. Every turn the Pontiac made was the very turn the officer needed to get to the accident scene.

    Hyde followed the Pontiac all the way to his destination (目的地). At that point he found another unit had already arrived at the accident scene. His help wasn’t needed. Now he was free to try to stop the driver of the Firebird, who by this time had developed something new to panic about.

    “Just about that time,” Hyde says, “I saw fire coming out from under that car, with blue smoke and oil going everywhere. He’d blown his engine. Now he had to stop.”

    “After I arrested him, I asked him why he was running. He told me he didn’t have a driver’s license(执照).”

That accident cost the driver of the Firebird plenty - a thousand dollars for the new engine- not to mention the charges for driving without a license, attempting to run away, and dangerous driving.

63. The meaning of “panicked” in Paragraph 2 is related to _____.

       A. shame B. hate    C. anger  D. fear

64. Why did the driver of the Firebird suddenly speed down the highway?

       A. Because he was racing with another driver on the road.

      B. Because he realized he had to hurry to the accident scene.

      C. Because he thought the police officer wanted to stop him.

      D. Because he wanted to overtake other cars on the shoulder.

65. Which of the following statements is true?

       A. Someone else was taking care of the injured person.

      B. The Pontiac reached its destination at the accident scene.

      C. Hyde knew where he was going by following the right car.

      D. The policeman was running after a speeder on Highway 40.

66. The driver of the Firebird ______.

       A. took a wrong turn on the way

      B. had some trouble with his car

      C. was stopped by the police officer

      D. paid for the expenses of the accident

67. What is probably the best title for the article?

       A. Losing His Way?   B. Going My Way?

      C. Fun All the Way?   D. Help on the Way?

Directions: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.
Sociologists have long recognised that organisations of less than 200 individuals can operate through the free flow of information among the members. Once their size goes beyond this figure, the organizations are getting less flexible. So it seems necessary to prevent total disorder resulting from failures of communication.
One solution to this problem would, of course, be to structure large organisations into smaller units of a size that can act as a group. By allowing these groups to build reliance on each other, larger organizations can be built up. However, merely having groups of, say, 150 will never of itself be a complete solution to the problems of the organization. Something else is needed: the people involved must be able to build direct personal relationships. To allow free flow of information, they have to be able to communicate with each other in a casual way. Maintaining too formal a structure of relationships inevitably prevents the way a system works.
The importance of this was drawn to my attention two years ago by the case of a TV station. Whether by chance or by design, it so happened that there were almost exactly 150 people in the station. The whole process worked very smoothly as an organization for many years until they were moved into purpose-built accommodation. Then, for no apparent reason, the work seemed to be more difficult to do, not to say less satisfying.
It was some time before they work out what the problem was. It turn out that, when the architects were designing the new building, they decided that the coffee room where everyone ate their sandwiches at lunch times was an unnecessary luxury and so did away with it. And with that, they accidentally destroyed the close social networks that strengthened the whole organization. What had apparently been happening was that, as people gathered informally over their sandwiches in the coffee room, useful information was casually being exchanged.
(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS.)
【小题1】What size of an organization may lead to communication failures?
【小题2】What are the two solutions to the communication problem within a large organization?
【小题3】After the TV station moved into new accommodation, its operation ___________________________.
【小题4】From the case of the TV station, we can conclude it is ____________________________________ that make(s) an organization more successful.

Kids will often ignore your requests for them to shut off the TV, start their chores(杂事),or do their homework as a way to avoid following your directions. Before you know it, you’ve started to sound like a broken record as you repeatedly ask them to do their assignments, clean their room, or take out the trash. Rather than saying “Do your chores now.” you’ll be more effective if you set a target time for when the chores have to be completed. So instead of arguing about starting chores, just say, “If chores aren’t done by 4 pm, here are the consequences.” Then it’s up to your child to complete the chores. Put the ball back in their court. Don’t argue or fight with them, just say,“ That’s the way it’s going to be.” It shouldn’t be punitive(惩罚性的)as much as it should be persuasive. “If your chores aren’t done by 4 pm, then no video game time until chores are done. And if finishing those chores runs into homework time, that’s going to be your loss.” On the other hand, when dealing with homework, keep it very simple. Have a time when homework starts, and at that time, all electronics go off and do not go back on until you see that their homework is done. If your kids say they have no homework, then they should use that time to study or read. Either way, there should be a time set aside when the electronics are off.

When a kid wears his iPod or headphones when you’re trying to talk to him, make no bones about it;he is not ignoring you, he is disrespecting you. At that point, everything else should stop until he takes the earplugs out of his ears. Don’t try to communicate with him when he’s wearing headphones—even if he tells you he can hear you. Wearing them while you’re talking to him is a sign of disrespect. Parents should be very tough about this kind of thing. Remember, mutual respect becomes more important as children mature.

1.According to the passage, it seldom happens that _______________________.

A.kids turn a deaf ear to their parents’ requests

B.parents’ directions sound like a broken record

C.children are ready to follow their parents’ directions

D.parents are unaware of what they are repeating to their kids

2.Parents will be able to deal with their children more effectively if they ________________.

A.avoid direct ways of punishment

B.make them do things at their request

C.argue and fight with their children

D.allow their children to behave in their own way

3.It can be inferred from the passage that _________________________.

A.parents should take off his headphones when trying to have a talk with their child

B.it will make no difference that a kid is wearing his earplugs while talking to his parents

C.parents shouldn’t give in to their kid when he shows no sign of respect

D.kids’ purposely talking to their parents with iPod gives them a sense of power and control

4.The main idea of the passage is ______________________________.

A.that respecting each other is more important than anything else

B.how kids behave to ignore and disrespect their parents

C.that children should make choices and decisions on their own

D.how parents can deal with their kids’ behavior effectively
