E
Twenty years ago, most experts believed that differences in how boys and girls behaved were mainly due to differences in how they were treated by their parents, teachers, and friends. It’s hard to cling to that belief today. Recent research has shown that there are biological differences between boys and girls. Understanding these differences is important in raising and educating children.
For example, girls are born with more sensitive hearing than boys, and the difference increases as kids grow up. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. Conversely (反过来), boys who appear to be inattentive in class may just be sitting too far away too hear the teacher.
Likewise, girls are better in their expression of feelings. Studies reveal that negative emotions are seated in an area of the brain called the amygdala. Girls develop all early connection between this area and the cerebral cortex (大脑皮层), enabling them to talk about their feelings. In boys these links develop later. So if you ask a troubled adolescent boy to tell you what his feelings are, he often cannot say much.
Dr. Sax, an advocate of single-sex education, points out that keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. Therefore, parents and teachers should try to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy.
67．What is the main idea of the passage?
A. Boys tend to pay less attention in class than girls.
B. Girls are better than boys in their ability to detect sounds.
C. Boys and girls behave differently because of biological differences.
D. Single-sex schools are not good because they keep boys and girls separate.
68．Why do girls express negative feelings better than boys?
A. Girls are more emotional than boys.
B. Girls have more brain cells than boys.
C. The amygdala is located in different areas of the brain for boys and girls.
D. The links between certain parts of the brain develop earlier in girls than in boys.
69．Which of the following does the author believe?
A. Girls need more training in communication.
B. Boys and girls should be educated in different ways.
C. Parents should pay more attention to boys.
D. Sex differences should be ignored in education。

D
　　Beyond two or three days，the world’s best weather forecasts are doubtful, and beyond six or seven they are worthless.
　　The Butterfly Effect is the reason. For small pieces of weather—to a global forecaster，small can mean thunder—storms and blizzards（暴风雪）—any prediction becomes worse rapidly. Errors and uncertainties increase，from dust devils and storms up to continent-size eddies（旋涡）that only satellites can see.
　　The modern weather models work with net-like points sixty miles apart，and even so，some starting data have to be guessed，since ground stations and satellites cannot see everywhere. But suppose the earth could be covered with sensors placed one foot apart，rising at one-foot intervals all the way to the top of the atmosphere. Suppose every sensor gives perfectly accurate readings of temperature，pressure，humidity（温度）, and any other data a weatherman would want. Exactly at noon a powerful computer takes all the data and calculates what will happen at each point at 12.01, then 12.02，then 12.03…the computer will still be unable to predict whether Princeton will have sun or rain one month away. At noon the spaces between the sensors will hide fluctuations（波动）that the computer will not know about. By 12.01，those fluctuations will already have created small errors one foot away. Soon the errors will have added to the ten-foot scale，and so on up to the size of the globe.
63．A weather forecast ____________ in the world.
A．is reliable within one or two days
B．is doubtful beyond 24 hours
C．becomes useless beyond two or three days
D．is still worthwhile in seven days
64．Usually there is a weather sub-station____________.
A．in every city 　　　　　　　　　　B．every 60 miles
C．between two cities 　　　　　　　 D．every one foot
65．Which of the following statements is true？
A．People have not placed sensors one foot apart in the atmosphere.
B．Scientists have already put sensors one foot apart in the world.
C．Every sensor gives perfectly accurate data a weatherman wants.
D．Ground weather stations and satellites can see every place on earth.
66．Our computer will not be able to know about fluctuations because ____________.
A．the sensors are not good enough
B．they are hidden by the spaces between the sensors
C．they are too far away
D．they move very fast

The quality of drinking water in Shanghai will meet European Union standard by 2010 and, a decade later, citizens in Shanghai will drink the best water in the world.
These were the goals set out by the Shanghai Water Authority. With the city’s population expected to increase only slightly and the economy to boom by 2020, Chen Yin, and official with the water authority, said Shanghai’s water consumption will not increase from its present amount.
Zhang Yue, director of the Urban Construction Division under the Ministry of Construction, said, “Shanghai is the first city in the country to publicize these ambitions. They will not be easy to achieve.”
He said water saving will help keep the sustainable development of China’s economy.
Saving one cubic meter of water means saving the city’s infrastructure（基础设施）costs by 10,000 Yuan. Last year, Shanghai saved 300 million cubic meters of water either from readjustment of industrial structure or the employment of new technology.
“The aim is to arouse public awareness of the seriousness of water shortages,” Chen said. “The abundant surface water and amount of rain of the city are so misleading that they result in improper use of water.”
Shanghai lacks drinkable water. The Huangpu River, which supplies 80 percent of the city’s drinkable water, is nearing exhaustion.
The city, therefore, has been exploring new sources from the Yangtze River and growing forests along it to conserve quality water.
Besides penning regulations, the authority is popularizing technology among the public to efficiently cut the amount of water used.
At present, the city has 600，000 family toilets, each using 13 liters of water per flush. These are to be renovated（整修）to use only 9 liters of water per flush.
The authority is renovating the first 200 toilets for households – at a cost of 40 Yuan each.
In three years, all the toilets will be renovated, which saves the city nearly 15 million Yuan every year in water conservation.
Another task the city is engaged in is the treatment of sewage（污水）to improve the water environment.
At present the city can only treat 44 percent of its daily 5.04 million tons of waste water. To meet the total demand, 27 more sewage treatment factories are to be established with an estimated investment of 18 billion Yuan.
41．People in Shanghai get their daily water mainly from _______now.
A．the underground                          B．the rain
C．the Yangtze River                         D．the Huangpu River
42．According to the passage, some people have the wrong opinion of using water
because      .
A．the renovating of family toilets will save plenty of water
B．about half of waste water has been treated already
C．advanced technology makes people use water as much as possible
D．there is plenty surface water and large amount of rain at present
43．The authority is renovating the first 200 toilets for households to          .
A．make people’s living more convenient
B．improve people’s living standards
C．ease employment pressure
D．meet the total demand of water
44．Which group of measures are all mentioned in the passage to save water?
a．improve drinking water quality
b．change some industrial structure
c．introduce or use some new technology
d．speed the economic development of Shanghai
e．renovate some family toilets
f．build more sewage treatment factories
A．a, b, c, d                       B．b, c, e, f
C．b, c, d, e              D．a, b, e, f
45．We can infer from the passage that          .
A．the boom of economy will need a larger amount of water in the future
B．citizens today in Shanghai drink the best quality of water in the world
C．not everyone today in Shanghai is aware of water shortage
D．all the family toilets will be renovated to save water within 3 years

Animation(动画) means making things which are lifeless come alive and move.
Since earliest times, people have always been surprised by movement. But not until this century have we managed to take control of movement, to record it, and in the case of animation, to retranslate it and recreate it. To do all this, we use a movie camera and a projector.
In the world of cartoon animation, nothing is impossible. You can make the characters do exactly what you want them to do.
A famous early cartoon character was Felix the Cat, created by Pat Sullivan in America in the early nineteen twenties. Felix was a wonderful cat. He could do all sorts of things no natural cat could do like taking off his tail, using it as a handle and then putting it back.
Most of the great early animators lived and worked in America, the home of the moving picture industry. The famous Walt Disney cartoon characters came to life after 1928. Popeye the Sailor and his girl friend Olive Oyo were born at Max Ficischer in 1933.
But to be an animator, you don’t have to be a professional. It is possible for anyone to make a simple animated film without using a camera at all. All you have to do is to draw directly on to an empty film and then run the film through a projector.
64. Which of the following statements is TRUE?
A. People were unable to cause the movement to last or record it in the last century.
B. Pat Sullivan was a famous early cartoon character.
C. It is impossible to make cartoon characters do what they are designed to do.

C. Popeye the Sailor and Olive Oyo were famous cartoonists
D. the cartoon industry started in the United States
67. Which of the following statements best describes the author’s attitude towards cartoon making?
A. Cartoon making is an easy job. Anyone can do it.
B. Only trained people can be employed in cartoon making industry.
C. Anyone can make cartoons under the instructions of professionals.
D. Cartoon making is no easy job. You have to spend much time drawing onto the empty film.

Protecting Copyright
Having finished her homework, Ma Li wants some music for relaxation （娱乐）. As usual, she starts her computer and goes to Baidu.com to download music files. But this time she is surprised when an announcement about protecting songs’ copyright bursts onto the screen. The age of free music and movie downloads may have come to an end as Web companies like Baidu are accused of pirating copyright. Lawsuits（诉讼） have been filed against four websites offering free downloads. In September 2005, a Beijing court ordered Baidu to pay recording company Shanghai Push compensation for their losses. Baidu was also told to block the links to the pirated music on the website. This caused a heated discussion on Interact file sharing.
“Baidu’s defeat in the lawsuit shows it is not right to get copyrighted songs without paying. Downloaders may face lawsuits or fines,” said an official.
Like many teens, Huang Ruoru, an 18-year-old girl from Puning in Guangdong Province, doesn’t think that getting music from websites is wrong. She always shares her favourite songs downloaded from Baidu with her friends. When told about the lawsuit, she began to feel a little guilty about obtaining others’ work without paying.
However, other teenagers have different ideas. Wang Yafei, a Senior 2 girl from Jinan, Shandong Province pointed out that file sharing is a good way to promote pop singers. “If I download a song and really like it, I will buy the CD,” she said. “So what the recording companies really should concentrate on is improving their music, rather than pursuing （追赶）file-sharers.”
1. Which of the following best describes the passage?
A. Music on the Internet is of better quality.
B. Downloading material can be illegal.
C. It’s good to get free music on the Internet.
D. Baidu is a popular web company.
2. The four web companies were put to court because _________.
A. they got copyrighted songs without paying
B. they downloaded copyrighted music for people
C. they make copyrighted files for free downloads
D. they offer free music on line
3. How do some of the teenagers feel while downloading free music after the lawsuit?
A. A bit guilty.        B. A little sad.      C. Extremely angry.   D. Awfully sorry.
4. What’s the advantage of file sharing for recording companies?
A. Getting more money from web companies.
B. Enabling people to download favorite songs.
C. Helping to improve the music.
D. Making pop singers more popular.
5. It can be inferred from the text that _________.
A. Web companies are still ignoring the copyright laws.
B. Teenagers haven’t got money to buy CDs.
