At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot.
There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can’t fly into the air from the ground. Their wings don’t produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can’t run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight.
During the hours when most enemies are active, bats gather where few animals would think to look and most can’t reach. This allows
them to disappear from the world until night comes again. There’s also little competition for these resting spots, as other flying animals don’t have the ability to hang upside down.
Bats have a unique physiological adaptation that lets them hang around this way without using a
ny energy. For you to hold your fist around an object tight, you contract（紧缩）several muscles in your arm, which are connected to your fingers by ten
dons（腱）；as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat’s talons（爪）close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn’t have to do anything to hang upside down.Bats hang upside down because________．
| A．they haven’t developed a pair of strong claws | B．they can’t start to fly from the ground directly |
| C．they have no hind legs to support their body | D．they can’t find quiet places to stay during the day |
The third paragraph tells us that bats’ hanging upside down_______.
| A．is to save their energy for night movement | B．is a way to fight against flying animals |
C．is a great way to hide from danger |
D．is a skill to compete for the flying places |
Why can bats hang upside down easily?
| A．Because their upper body is light. |
| B．Because they have strong muscles. |
| C．Because their talons are linked to muscles tightly. |
| D．Because their tendons are linked to their upper body. |
What is the passage mainly about?
| A．The living habits of bats. | B．How and why bats  hang upside down. |
| C．The importance of bats’ hanging upside down. | D．How bats use their energy at night. |

Ireland has had a very difficult history. The problems started in the 16th century when English rulers fried to conquer(征服) Ireland. For hundreds of years, the Irish people fought against the English. Finally, in 1921. The British government was forced to give independence to the south of Ireland. The result is that today there are two “Irelands”. Northern Ireland. In the north, is part of the united kingdom. The republic of Ireland. In the south. Is an independent country.
In the 1840s the main crop, potatoes ,was affected by disease and about 750,000 people died of bunger.

For many years, the majority of Irish people earned their living as farmers. Today, many people still work on the land but more and more people are moving to the cities to work in factories and offices.

How often one hears children wishing they were grown up, and the old wishing they were young again! Each age has its pleasure and its pains, and the happiest person is the one who enjoys what each age gives him without wasting any time in useless regrets.
Children is a time when there are few duties to make life hard. If a child has good parents, he is fed, looked after, and loved whatever he may do. It’s impossible for him to be given so much again in his life without having to do anything in return. Besides, life is always giving new things to the child. A child finds pleasure in playing in the rain, or in the snow. His first visit to the seaside makes him wild. But a child has his pains; he is not so free to do as he wishes. He is continually being told not to do this, not to do that, or being punished for what he has done wrong. His life is therefore not perfectly happy.
When the young man starts to make his own living, he becomes free from the rules of school and parents; but at the time he is forced to accept duties. He can no longer expect others to pay for his food, his clothes and his room, but has to work for them if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry and suffer. And if he breaks the law of society as he used to break the laws of his parents, he may go to prison, lf, however, he works hard, keeps out of trouble, and has good health, he can have the great happiness of seeing himself make steady progress in his job and of building up his own position in society and enjoy success and good reputation..
Old age has always been thought of as the worst age to be, but it is not necessary for the old to be unhappy. Old age has its own happiness. They can have the joy of seeing their children making progress in life; they can watch their grandchildren growing up around them and, perhaps, best of all, they can, if their life has been a useful one, feel the happiness of having come through the battle of life safely and of having reached a time when they can lie back and rest, leaving others to continue the fight.The main reason children wish they were grown up, and the old wish they were young again is that ______.
| A．both aren’t satisfied with the weak points at their ages |
| B．both enjoy the strong points at the other age by looking back or looking forward |
| C．the human beings should be like this |
| D．they don’t think both ages are acceptable |
“Enjoy what each age gives him without wasting time in useless regrets” means ______.
| A．Enjoy what is given to him by people at his age, feeling regrets |
| B．Enjoy himself at his own age, feeling regrets for a waste of time |
| C．Make full use of the time he is given at his age instead of regretting having no achievements |
| D．Enjoy his own age and look down on the people at other ages |
“Children is a time when there are few duties to make life hard” means “______”.
| A．Children shouldn’t be made to live a hard life |
| B．All the children won’t have to work for their own living |
| C．Children shouldn’t answer for the hard life they are leading |
| D．A child bas few duties to try hard to make a living for himself or for his seniors |

| B．He thinks he knows less about things than the older do. |

A year after graduation, I was offered a position teaching a writing class. Teaching was a profession I had never seriously considered, though several of my stories had been published. I accepted the job without hesitation, as it would allow me to wear a tie and go by the name of Mr. Davis. My father went by the same name, and I liked to imagine people getting the two of us confused. “Wait a minute,” someone might say, “are you talking about Mr. Davis the retired man, or Mr. Davis the respectable scholar?”
The position was offered at the last minute, and I was given two weeks to prepare, a period I spent searching for briefcase (公文包) and standing before my full-length mirror, repeating the words, “Hello, class. I’m Mr. Davis.” Sometimes I would give myself an aggressive voice. Sometimes I would sound experienced. But when the day eventually came, my nerves kicked in and the true Mr. Davis was there. I sounded not like a thoughtful professor, but rather a 12-year-old boy.
I arrived in the classroom with paper cards designed in the shape of maple leaves. I had cut them myself out of orange construction paper. I saw nine students along a long table. I handed out the cards, and the students wrote down their names and fastened them to their breast pockets as I required.
“All right then,” I said. “Okay, here we go.” Then I opened my briefcase and realized that I had never thought beyond this moment. I had been thinking that the students would be the first to talk, offering their thoughts and opinions on the events of the day. I had imagined that I would sit at the edge of the desk, overlooking a forests of hands. Every student would yell. “Calm down, you’ll all get your turn. One at a time, one at a time!”
A terrible silence ruled the room, and seeing no other opinions, I inspected the students to pull out their notebooks and write a brief essay related to the theme of deep disappointment.The author took the job to teach writing because ______.
| A．he wanted to be expected |
| B．he had written some storied |
