The scientists from the Lockheed Space Company (公司) work in Felton, California, with the help of a computer. But the computer is placed in Sunnyside, about 80 kilometers away. What the scientists input is sent by telephone lines to the computer, and after a time, copies of the designs are needed back in Felton as possible. Lockheed people have tried several ways of sending the prints (印刷品), but the most effective seems to be by pigeon (鴿子). Are pigeons really used to carry messages in these days? They are, and they send the prints faster and cheaper than any other way.
Human (人類的) messengers (persons carrying messages) are much more expensive and slower than the pigeons. The road to Felton goes through the mountains, and the driving is not easy. An electronic printout system(電子印刷系統(tǒng)) could do the work in Felton, but at a cost of 10 dollars a print. Pigeons carry the designs for about 1 dollar each.
Now Lockheed people have ten pigeon messengers. The pigeons do the work, and they have made Lockheed more famous. You can often read the news about the pigeons in the newspapers around the world.

Chinese are very generous when it comes to educating their children. Not caring about the  money, parents often send their children to the best schools or even abroad to England, the United States and Australia. They also want their children to take extra-course activities where they will either learn a musical instrument(樂(lè)器) or ballet, or other classes which will give them a head in life. The Chinese believe that the more expensive an education is, the better it is. So parents will spend an unreasonable amount of money on education. Even poor couples will buy a computer for their son or daughter. However, what most parents fail to see is that the best early education they can give their children is usually very cheap.
Parents can see that their children are very skilled in some areas while poor in others. What most parents fail to realize though, is that today's children are short of self-respect and self-confidence.
The problem is that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills that they need to be confident, happy and clever.
Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework. Teaching a child to cook will improve many of the skills that he will need later in life. Cooking requires patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and finish his job successfully step by step. His result, a well-cooked dinner, will give him much satisfaction and lots of self-confidence.
Some old machines, such as a broken radio or TV set that you give your child to play with will make him curious and arouse(激發(fā)) his interest. He will spend hours looking at them, trying to fix them; your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.
【小題1】Most Chinese parents don't realize_______.

A．how much the best education is worthB．when children should be educated
C．what children really need in later lifeD．why school tests don't satisfy children
【小題2】What is the main idea of the last paragraph?
A．Fixing old machines is very important. B．Interest is necessary for everything.
C．Broken things are useful for children.D．Using hands helps improve thinking ability.
【小題3】The writer's attitude（看法） to children's education is that
A．the cheaper an education is, the better it is
B．children today should learn different skills
C．practical skills are useful to children's growth
D．school education can't meet parents' expectation.

Can plants eat people? Probably not，but there are many plants that eat meat．Some of them are big．And they can eat small animals．One famous meat-eating plant is the Venus flytrap(捕蠅草)．
The Venus flytrap is a very strange plant．It grows in dry parts of the United States．Its leaves are like the pages of a book．They can open and close very quickly．Inside the leaves，there are three small hairs．If a fly touches one of the hairs，the leaf closes quickly．The fly cannot get out．In about half an hour，the leaf presses the fly until it is dead．Then，the plant covers the fly．Slowly，the plant eats the fly．
Why do plants do it? Most plants get what they need from the sun，the air，and the ground．In some places，the ground is very poor．It doesn’t have all these important things，

Recent research from the Pew Internet Project suggests that 90% of Americans aged from 12 to 17 use the Internet, and 51% of those teens use social networks. However, there are many possible problems with social networking sites and the teenagers who use them.

Apart from the social advantages, social networking sites can be used to record school research, develop artistic talents and experiment with other forms of subject creation. They provide a way to communicate with others who share the same interests and to get helpful advice on ongoing projects.
Along with these advantages come some dangers. For example, most social networking sites are open to all, especially MySpace, which is the most popular social network among teens in America. It means that they could be put in unpleasant and frightening situations.
A greater danger is that teens may become objects of the people with secret purposes. The secrecy of some social networking sites makes it easy for dangerous people to find young teens and invite them into dangerous conversations. It’s easy for them to pretend as teens and draw children into dangerous real-world communication as well. Then further hurt might be on its way.
Another danger is identity stealing, which can happen when teens share too much information about their names, dates of birth and locations.
Therefore, it’s very important to make sure teens are safe when they use social networks.
Many of the same rules that work for online chat work for these sites:
※Don’t use your real name.
※ Don’t give out personal information to people you don’t know. A last name and a town
are enough for a bad guy to find where you are.
※ Don’t believe that people are who they say to be.
※ Immediately end any communication that makes you uncomfortable and report it to a
parent.
Only if you are sure of your safety, can you enjoy the fun brought by social networking. Besides, trying to deal with all problems on your own can lead to terrible results. Remember, asking your parents or school officials for help doesn’t mean you are unable to do anything but wiser than many others.                                             
【小題1】How many dangers of using social networks are mentioned in the passage?

A．2.B．3.C．4.D．5.
【小題2】The writer takes MySpace as an example to show that ________.
A．students could be put into unreal situations on the Internet
B．teenagers are facing unknown dangers on the social networks
C．Internet provides more social websites to American teenagers
D．social networks are very popular among teenagers in America
【小題3】We can infer from the passage that ________.
A．the dangers are similar when chatting online and surfing social networks
B．more than half American teenagers aged from 12 to 17 use social networks
C．teens who ask for help are wiser when meeting problems on social networks
D．there are more disadvantages than advantages for teens to use social networks

閱讀下列短文，根據(jù)短文內(nèi)容，回答下列問(wèn)題。
Save water, save lives
A BOTTLE of water may not seem like much to you, but it can save the day for people who live in drought-hit (遭受旱災(zāi)) areas in China.
In the past few months, some places in southwest China experienced a serious drought. In Yunnan, Guangxi, Sichuan, Guizhou and Chongqing, there has been very little rain since last autumn. Crops died, the land cracked, and wells (井) and rivers dried up. More than 20 million people are having difficulty finding safe drinking water.
After learning about the drought, many people around the country helped by giving water, money and other resources.
Last week, China asked every member of the Communist Youth League (團(tuán)員) and Young Pioneers (少先隊(duì)員) to give one bottle of water to the drought-hit area. Students in primary schools and middle schools quickly joined the activity.
“A bottle of water isn’t much, but thousands of bottles will be of great use,” said Zhang Zihao, a middle school student at Tongling No 1 Middle School in Anhui.
In Yuhua Primary School in Xi’an, 900 students bought over 100 bottles of water with their pocket money. They also wrote their wishes on the bottles.
The serious drought has also made students realize the importance of saving water.
Students from Nanshan Middle School in Huizhou in Guangdong went on the street to tell people to take part in water-saving activities.
“I heard that some children in drought-hit areas don’t have enough drinking water. They have to drink muddy (泥濘的) water. I feel really sad about that,” said one student. “I decided to take a shower twice a week instead of every day to save water.” he said.
【小題1】Why did a serious drought happen in Southwest China?
                                                                       
【小題2】What does the underlined（劃線的）word “cracked” probably mean in Chinese?
                                                                       
【小題3】What did people do after learning about the drought?
                                                                       
【小題4】Is a bottle of water helpful for the people in drought-hit areas?
                                                                       
【小題5】What can you learn from the passage?

The temperature is usually about -25℃, but it’s sometimes much colder. When it’s -35℃, children can’t go to school, but grown-ups still go to work!

In winter, we close the windows to stop the wind from getting in, and we don’t open them again until spring.
In spring and summer it rains a lot, and we don’t often see the sun. In summer it’s often about 25℃, but the weather is very changeable. One day it’s 25℃, and the next day it’s 10℃. People say that the weather was even colder in the past.
