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 |
| B．science courses make them more popular |
| C．science courses make them successful |
| D．science courses are difficult for them |
Thetext mainly discusses __________ reasons for thedifference between boys and girls in scientific achievements.

Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country's economy. It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance the wealth and happiness of local inhabitants.
Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country's economy can suffer.
On the other hand, if there is not enough tourism, people can lose jobs. Businesses can also lose money. It costs a great deal of money to build large hotels, airports, air terminals, first-class roads, and other support facilities (配套设施) needed by tourist attractions. For example, a major international class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel lose money.
Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.Which of the following do you think has been discussed in the part before this selection?
| A．It is extremely important to develop tourism. |
| B．Building roads and hotels is essential. |
| C．Support facilities are highly necessary. |
| D．Planning is of great importance to tourism. |
The underlined word "inhabitants" (in Paragraph 1) probably means __________.
| A．tourists | B．passengers |
| C．population | D．citizens |
Too much tourism can cause all these problems EXCEPT __________.
| A．a bad effect on other industries |
| B．a change of tourists' customs |
| C．over-crowdedness of places of interest |
| D．pressure on traffic |
It can be inferred from the text that __________.
| A．the author doesn't like tourism developing so fast |
| B．local people will benefit from tourism |
| C．other parts of a country's economy won't benefit from tourism much |
| D．we can't build too many support facilities |
The author thinks it is good for local people to know that tourism will __________.
| A．waste a lot of money |
| B．weaken their economy |
| C．help establish their customs |
| D．help improve their life |

In the morning, we went camping along a path in Green Natural Park. We were happy because it was a sunny day. We were expecting an enjoyable two-day holiday. On the way, we kept singing and making jokes.
However, in the afternoon, when we finished our picnic at one o'clock, it was dark and windy. Soon, there was a shower. Unluckily, none of us brought an umbrella. We ran about but we could find no place to hide.
Twenty minutes passed and it was still raining, There were hours to go before we reached the campsite (野营地). It was even worse that our small compass (指南针) showed that we went to the wrong way. We had lost our way!
We had to make a quick decision as it was raining heavily. Chris said we could set up a tent to hide in, so Mary and Tom helped to set up the tent. Chris and I tried to make a fire to keep us warm.

Swiss national Louis Palmer fulfilled a childhood dream when he set off from his mother country on July 3, travelling over deserts, cities and seas in 17 countries in a solar taxi to reach UN Climate Change Conference in Bali, Indonesia.
"In 1986, 1 was a 14-year-old boy. I was dreaming that when I will be an adult. I want to drive around the world, " he told reporters.
"Then it came to my mind, how can I travel around the world and enjoy the beauty of this world with a car that is polluting the world? Then I thought the perfect car would be a solar car. "
His car, which has become a major attraction at the gates of the summit of some 188 nations, was built in three years with scientific help from four universities and 15 Swiss companies. The car pulls a trailer with six square meters of solar panels which absorb the sun. The electricity is fed into the battery which powers the car, and can run for up to 100 kilometers a day.
"It's the first time in history that a car is driving around the world without a single drop of petrol, " said Palmer.
His epic solar journey is not his first adventure—he crossed Africa on a bicycle and North America in a light aircraft.
So far, Palmer has gone by land through Europe and the Middle East, then by sea to India and on to Indonesia. After covering much of Asia, Australia, North America and Africa, he will return to Switzerland to try and drum up support for the commercial possibilities of solar cars.
For the moment, he has his hands full, with more curious customers waiting to take a ride in his unique automobile which, he said, "works like a Swiss clock. "The sentence in the third paragraph "how can I travel around the world and enjoy the beauty of this world with a car that is polluting the world?" means" __________ ".
| A．Louis Palmer found it hard to choose how to travel |
| B．Louis Palmer would feel guilty about his travelling in a polluting car |
| C．Louis Palmer couldn't make up his mind whether to travel by car |
| D．Louis Palmer was trying to enjoy the scenery in spite of polluting the world |
Why did Louis Palmer take so long a journey in a "solar taxi"?
| A．To attend the conference. |
| B．To advertise the solar car. |
| C．To realize his dream. |
| D．To turn to the summit for help. |
So many visitors came to the car mainly because __________.
| A．it uses electricity as power |
| B．it works as well as a Swiss clock |
| C．it is the first solar car in the world |
| D．they were eager to have a look at it |
The underlined phrase "has his hands full" in the last paragraph probably means __________.
| A．becomes very popular | B．looks so proud |
| C．is extremely busy | D．shakes hands |

Long bus rides are like television shows. They have a beginning, a middle, and an end—with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. "Buy Super Clean Toothpaste. " "Drink Good'n Wet Root Beer. " "Fill up with Pacific Gas. " Only if you sleep, which is equal to turning the television set off, are you spared the unending cry of “ You Need It! Buy It Now!"?
The beginning of the ride is comfortable and somewhat exciting, even if you've traveled that way before. Usually some things have changed—new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it's fun to try to figure it out the first hour or so. If the driver is particularly reckless or daring, the ride can be as thrilling as a suspense story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you've got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.
The end of the ride is somewhat like the beginning. You know it will soon be over and there's a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you've sat with your legs crossed, with your hands in your lap, with your hands on the arm rests—even with your hands crossed behind your head. The end comes just at no more ways to sit.According to the writer, long bus rides and TV shows are similar in that __________.
| A．they are both long and boring, with commercials disturbing you all the time |
| B．they both have a beginning, middle, and an end, with commercials in between |
| C．they are both exciting, with new things to see in every three or four minutes |
| D．they both make you sit in your seat uncomfortably for a very long time |
The writer sounds as if he likes __________.
| A．reckless bus drivers | B．sleeping on bus trips |
| C．salty food | D．commercials |
The writer thinks that the end of the ride is somewhat like the beginning because both are __________.
| A．tiring | B．comfortable | C．exciting | D．boring |

I was blind, but I was ashamed of it if it was known. I refused to use a white stick and hated asking for help. After all, I was a teenage girl, and I couldn't bear people looking at me and thinking I was not like them. I must have been a terrible danger on the roads; coming across me wandering through the traffic, motorists probably would have to step rapidly on their brakes. Apart from that, there were all sorts of disasters that used to occur on the way to and from work.
One evening, I got off the bus about hallway home where I had to change buses, and as usual I ran into something, "I'm awfully sorry, " I said and stepped forward only to run into it again. When it happened a third time, I realized I had been apologizing to a lamp post. This was just one of the stupid things that constantly happened to me. So I carried on and found the bus stop, which was a request stop, where the bus wouldn't stop unless passengers wanted to get on or off. No one else was there and I had to try to guess if the bus had arrived.
Generally in this situation, because I hated showing I was blind by asking for help, I tried to guess at the sound. Sometimes I would stop a big lorry and stand there feeling stupid as it drew away. In the end, I usually managed to swallow my pride and ask someone at the stop for help.
But on this particular evening no one joined me at the stop; it seemed that everyone had suddenly decided not to travel by bus. Of course I heard plenty of buses pass, or I thought I did. But because I had given up stopping them for fear of making a fool of myself, I let them all go by. I stood there alone for half an hour without stopping one. Then I gave up. I decided to walk on to the next stop.The girl refused to ask for help because she thought __________.

| A．began to run | B．hit a person as usual |
| C．hit a lamp post by accident | D．was caught by something |
At the request stop that evening, the girl __________.
| A．stopped a big lorry |
| B．stopped the wrong bus |
| C．made no attempt to stop the bus |
| D．was not noticed by other people |
What was the problem with guessing at the sound to stop a bus?
| A．Other vehicles also stopped there. |
| B．it was unreliable for making judgments. |
| C．More lorries than buses responded to the girl. |
