Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.
It's always a good idea to put on your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break.
Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard.
Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849.
Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe.
小題1:The passage mainly tells us                  .
A.two important ways to keep safe in carsB.how air bags work to make cars safe
C.how seat belts work to make cars safeD.why we must tie the egg to the skateboard
小題2:The writer gives the example of the egg to _.
A.tell us that eggs are easy to break
B.show how to wear a seat belt

小題3:Seat belts can make us safer because .

B.they can stop us from hitting other cars
C.they can help us stay safely on the seats
D.they are made of strong materials
小題4:Air bags are important for cars because _.
A.they are made of plastic
B.they can also help us to keep safe in a car
C.they can keep cars running slowly
D.they are put in front of and next to the seats
小題5:Which of the following is TRUE according to this passage?
A.It won't be dangerous if there are seat belts or air bags in a car.
B.Now most of new cars still have only one air bag.
C.When a car hits something, its air bags will come out a few minutes later.

You can’t see any object unless light from that object gets into your eyes.Some of the things you see give off light of their own。The sun,the stars,a lighted lamp are the examples that can be seen by their own light.But most of the things you see are not giving off light of their own.They are just reflecting(反射)light that falls on them from the sun or some other luminous bodies.The moon,for example,doesn’t give off any light of its own.It is not 1uminous.You see it because sunlight falls on it and some of the sunlight reflects on the earth.So moonlight is only second—hand sunlight.
When you look at a book,it sends some of the light which fails on it to your eyes,and you see the book.If light could be kept out from where you’re so that there would be no light from the book to reflect.Then you couldn’t see the book even with your eyes wide open.Light travels so fast that the time in which it travels from the book you’re reading to your eyes is as short as if there were no time at time.Light reaches us from the moon,which is about 380,000 kilometres away,in only a little more than a second.
小題1:You can see the book because________.
A.your eyes are close to itB.it reflects some of the light
C.it has light of its ownD.it is big enough to be seen
小題2:The Chinese meaning of the world“luminous”is close to_______.
A.閃光的B.看不見的C.發光的D.明亮的
小題3:________has light of its own.
A.The moonB.The earthC.The sunD.The satellite of Dong Fong Hong
小題4:Light travels about_________kilometers per second.
A.300,000B.100,000C.400,000D.190,000
小題5:Which of the following is TRUE?
A.All the things you can see give off light.
B.Light from the book is much faster than that from the moon.
C.The moment you open your eyes,the light from the book travels to your eyes.

   What is an e–reader? An e–reader is a small computer. It can hold thousands 
of e–books. So people want to throw away heavy schoolbags and read with small, light e–readers.
For example, a US high school has put its paper books away. Teachers and students are using e–readers now. “It’s so convenient. You can have so many books right at your fingertips.” said Meghan Chenausky,16.
Chinese schoolchildren are also trying e–readers. Hanvon WISEreader is the most popular e–reader in China. It weighs about 260g and is as big as a regular textbook. It is a special e–reader. Students can make notes on it. They can use it to download textbooks from school computers. It can also send and receive homework.
New e–readers are not just for reading. They have WI-FI(無線網絡) and multimedia(多媒體).Parents think these may hurt children’s study habits. “I think WI-FI is not necessary for kids.” says Zeng Wenwen,43, Beijing.
   根據短文內容,判斷下列句了正誤。正確為“T”,錯誤為“F”。并在答題卡上把“T”或“F”涂黑。
小題1:An e–reader can keep thousands of e–books.
小題2:An e–reader can help to make schoolbags lighter than before.
小題3:In every US school, e–readers are used instead of paper textbooks.
小題4:The passage mainly introduces the size of an e–reader.
小題5:A different opinion is against the WI-FI and multimedia of e–readers.

What is your favorite color? Do you like yellow, orange, or red? If you do, you must be an active person who enjoys life. Do you like blue? Then you are probably quiet, shy, and would rather follow than lead.
Colors do influence our moods (情緒). A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing(令人壓抑的). There was a black bridge over the Thames River, near London. The number of people who killed themselves on that bridge used to be larger than on any other bridge in the area -- until it was repainted green.
Light and bright colors make people not only happier but also more active. In the factory, the workers will work better, harder, and have fewer accidents when their machines are painted orange rather than black.
小題1: An active person may like
A.yellow, orange, or redB.yellow, black, or red
C.orange, blue, or blackD.black, red, or orange
小題2:Most people feel more __ in a yellow room than in a dark green one.
A.tiredB.boredC.worriedD.relaxed
小題3: More people killed themselves on the black bridge than on any other bridge probably because ____
A.the bridge was very tallB.the bridge was too crowded
C.people didn’t like the bridgeD.the color of the bridge was depressing
小題4: In the factory, when the machines are painted orange, the workers will work __
A.worseB.harderC.more slowlyD.more angrily
小題5:Which could be the best title for the passage?
A.Cheerful ColorsB.Your Favorite Color

If you take away many sentences from somebody's written work as your own without permission, it's called plagiarism,but if you take the knowledge from a piece of work by another and change the words, then it's not plagiarism. This is the difference between using the Internet and plagiarism. If you are given homework to work out math problems, then you should use your brain without a computer! If the teacher asks you to learn something about a famous literary person, you can use the computer. If you take down the main important information of the task, it’s OK. However, if you run to the computer to do your thinking for you all the time, you don’t exercise your brain and you will forget how to work out a problem. By using a computer, students may get a useful answer fast, to finish homework, but when they have to face an exam, they will not be ready for it.
Though teachers say finding or buying homework answers online is not many in schools, an interview with school students shows only 10% hopes to finish their holiday homework by themselves. They complain that the homework is too much for them to finish. Besides, many of students have to go to all kinds of training classes during the holiday. These take away much of their time for doing homework. So they want to find or even buy answers online or copy each other's homework. Students should learn that being a student is about getting skills, but not just getting quick, cheap "answers" for homework problems. I mean we should use the computer properly.
小題1:If you want to look up some information about something or somebody, you____.
A.should work it out by yourself
B.can turn to a computer for help
C.must discuss it with your teacher
D.will meet problems with plagiarism
小題2:Which belongs to plagiarism according to the text?
A.Answering questions in our own words.
B.Buying homework answers on the Internet.
C.Copying others’ written work without permission.
D.Doing our homework with the help of a computer.
小題3:Which is NOT the reason why the students hope to buy homework answers online?
A.The answers are cheap and quick.
B.They can exercise their brains all the time.
C.They have to go to all kinds of training classes during the holiday.
D.They have too much homework to finish.
小題4:What's the author's attitude towards using the computer for homework answers?
A.Using it for math problems.
B.Using it all the time for the homework.
C.Using it to get some information on the answers.
D.Using it when there's too much homework to finish.
