If there is no difference in general intelligence(智力）between boys and girls, what can explain girls' poor performance in science and mathematics?
It seems to be that their treatment at school is a direct cause. Mathematics and science are seen as subjects mainly for boys, and therefore, as girls become teenagers, they are less likely to take them. Interestingly, both boys and girls often regard the subjects for boys as more difficult. Yet it has been suggested that girls do not take mathematics courses, not because they are difficult, but for social reasons. Girls do not want to be in open competition with boys because they are afraid to appear less feminine (女性的）and attractive.
However, if we examine the performance of boys and girls who have taken mathematics courses, there are still more high-achieving boys than there are girls. This difference appears to be worldwide. Biological explanations have been offered for this, bat there are other explanations, too.
Perhaps the difference which comes out during the teenage years has its roots in much earlier experiences. From their first days in kindergarten, boys are encouraged to work on their own and to complete tasks. Facts show that outstanding mathematicians and scientists have not had teachers who supplied answers.
Besides, there can be little doubt that teachers of mathematics and science expect their boy students to do better at these subjects than their girl students. They even appear to encourage the difference between boys and girls. They spend more time with the boy students, giving them more time to answer questions and working harder to get correct answers from them. They are more likely to call on boys for answers and to allow them to take the lead in classroom discussion. They also praise boys more frequently. All of this seems to encourage boys to work harder in science and mathematics and to give them confidence that they are able to succeed.
Such a way of teaching is not likely to encourage girls to take many mathematics and science courses, nor is it likely to support girls who do. When it comes to these subjects, it seems certain that school widens the difference between boys and girls. Girls are likely to think that __________
| A．science courses are for both boys and girls |

The Great Fire of London started in the very early hours of September 2, 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. Over one hundred people became homeless, but only a few lost their lives .
The fire started on Sunday morning in the house of the King’s baker（面包师）in Pudding Lane. The baker, with his wife and family, was able to get out through a window into the roof. A strong wind blew the fire from the bakery（面包房）into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.
By eight o’clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul’s and the Guildhall among them .
Samuel Pepys , the famous writer, writer about the fire, “People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat .”
The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path（路径） of the fire.With nothing left to burn, the fire became weak and finally died out.
After the fire, Christopher Wren, the architect(建筑师), wanted a city with wider streets and fine new houses of stone．In fact, the streets are still narrow, but he did build more than fifty churches, among which was the new St Paul’s
The fire caused great pain and loss, but after it London was a better place: a city for the future and not just of the past.The underlined word‘family’in the second paragraph probably means____.
| A．house | B．children | C．wife and husband | D．wife and children |

A young woman carrying a three-year-old child got on a bus. The conductor(售票员) hurried to give her a warm welcome and then kindly asked the other passengers to make more room for the woman and her child. On seeing this, people began to talk. "You know this conductor used to be very rude. Now suddenly he has changed his bad behavior , "said a middle-aged man.
"Yes, he should be praised and we must write a letter to the company," said a second passenger. "That's right," another lady said, "I wish a newspaper reporter were here so that more people could learn from this conductor. "

Scientists are trying to make the deserts ,which get very little rain, into good land again. They want to bring water to the deserts，so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming desert all the time. Scientists may not be able to change the desert in time．
Why is more and more land becoming desert？Scientists think that people make deserts．People are doing bad things to the earth against the scientists’ wish．
Some places on the earth don’t get much rain. But they still don’t become deserts．This is because some green plants are growing there．Small green plants and grass are very important to dry places．Plants don’t let the sun make the earth even drier． Plants do not let the wind blow the dirt away．When a bit of rain falls，the plants hold the water. Without plants, the land can become desert more easily． Deserts ____________ ．
| A．never have any plants or animals in them |
| B．can all be turned into good land before long |
| C．are becoming smaller and smaller |
| D．get very little rain |
More and more landisbecomingdesertbecause____________．
| A．plants can’t grow there |
| B．there is not enough rain |
| C．people haven’t done what scientists wish them to do |
| D．scientists know little about the deserts |
Smallgreenplantsareveryimportanttodryplaces because ________
| A．they don’t let the sun make the earth even drier |
| B．they don’t let the wind blow the soil away |
| C．they hold water |
| D．All of the above． |
After reading this passage, we learn that _____________ ．

Ban Fur? Then Why Not Leather?
Much to the displeasure of some local businesses, the City Council in West Hollywood, California, voted without opposition last week to ban the sale of fur products. Should laws be involved in this issue? Is it unfair to ban sales of fur, but not sales of leather and hides (兽皮)?
Animals Do Not Have Rights
By Tibor R. Machan
My view is that animals do not have basic rights. It is a matter of ethics (伦理学) and not of the laws of human societies. If animals had such rights as human beings do, they would have to be held responsible for killing fellow animals in the wild. That way of thinking about animals makes a category mistake. Using animals, including their fur or organs, to improve people's lives is acceptable.
A Small Step Against Cruelty
By Kate Carter
Both fur and leather are the skins of dead animals. Why should we think that the lovable furry ones deserve more of a life than the less pleasing ones? Some say leather is less cruel because it's a byproduct (副产品) of the meat industry. But this isn't really true. Some cheap leather may be a byproduct of the meat industry, but often it's the other way round. In South Africa, where there is a developing market for ostrich(鸵鸟)farms, the skins account for roughly 80 percent of the slaughtered (宰杀)birds' value, a mere 20 percent of which comes from the meat.
"Who" Are You Wearing?
By Marc Bekoff
West Hollywood's ban is a move in the right direction. However, we must work to ban the sales of leather and hides, too. Furs come from animals who are attacked to become clothing, while some leather and hides come from slaughterhouse(屠宰场) animals. We must remember that when people choose to wear fur, leather and hides, they are wearing formering conscious beings. So it's a matter of who they are wearing, not what they are wearing because these animals must be referred to as who and not what or that.What is the passage mainly about?
| A．West Hollywood's ban on fur products. |
| B．Differences between fur and leather sales. |
| C．The government's role in protecting animals. |
| D．The ecological imbalance in West Hollywood. |
What is Kate Carter's opinion about wearing fur and wearing leather?
| A．Both are decided by the meat industry. |
| B．There is little distinction (区别) between them. |
| C．Wearing fur is generally more acceptable. |
| D．Wearing leather is cheaper than wearing fur. |
What is Marc Bekoff’s attitude towards sales of fur?
| A．Sympathetic. | B．Careless. | C．Tolerant. | D．Opposed. |
