When the traffic lights turn red, we will stop driving a car or crossing a street. Why is red used for traffic lights instead of other colors?
As we know, scattering (散射) happens when light goes through the air. For the same media(媒質(zhì)), if the wavelength islong, the scattering will be short. If the wavelength is short, then the scattering will be long.
Of all lights we can see red has the longest wavelength, so the scattering is the weakest. That means the red light travels far. In fact, it travels farther on rainy days.
Using the red light can help drivers in farther areas sec the lights. It helps drivers stow down or stop in lime. If drivers don't see the red light until they are close, they may not be able to stop the car in time. An accident may happen Red can also excite people. We can act more quickly when we see the color red. In a word, red lights help drivers stop in time and help prevent accidents.
小題1:When the traffic lights turn ______, we will stop driving a car.
A. red    B green     C. yellow
小題2:According to the passage, the scattering of the red light is the _______.
A. longest    b. weakest       C. farthest

Beyond Baby Mozart, Students Who Rock
Music education hasn’t changed much since the 1970s. Students are still taught to read notation(樂(lè)譜) so they can recite compositions that they would never listen to on their MP3 players or play with friends. Playing music enriches life. The question is: Why do schools teach music in a way that turns off so many young people rather than catch their imagination? Can we do a better job of using the power of music to get kids excited about school?
The experience of an organization called Little Kids Rock suggests the answer is yes — if we change the way music is taught. Little Kids Rock has helped music programs in over a thousand public schools and served 150,000 children. The organization has given 30,000 free instruments out, mainly guitars, and trained 1,500 teachers to run music classes in which students quickly experience the joys of playing their favorite songs, performing in bands(樂(lè)隊(duì)), and writing their own music.

The key to Little Kids Rock is that it teaches children to play music the way many musicians learn to play it — not by notation, but by listening, imitation(模仿) and meaningful experimentation. “The knowledge you need to get started playing rock music is very limited,” explains Dave Wish, the founder of Little Kids Rock. “In high school, my friend Paul taught me a couple of chords(和弦) and my life was changed forever. On the first day of class, Little Kids Rock teachers place guitars in the hands of their students and get them practicing chords that will enable them to play thousands of songs. The kids decide what songs they want to learn and the class is off and running. Their progress is surprising. Within a year, eight and nine-year-olds are playing musical instruments, and giving concerts, even performing their own songs.
One of the biggest advantages that music offers is the ability to encourage students who are otherwise bored by school. “I’ve had students start coming back to school because of this program,” said Adkison Thomas, who heads up music for the Dallas Independent School District. He added, “One of the best things is that the teachers discover a new side of their students. They see kids become successful who weren’t before.”
小題1:The expression “turn off” in Paragraph 1 means “______”.
A.make kids feel coolB.make kids feel bored
C.make kids feel confidentD.make kids feel nervous
小題2:How did Little Kids Rock help the school?
A.By writing music for kids.
B.By playing kids’ favorite songs.
C.By making instruments for school.
D.By training teachers for music classes.
小題3:Little Kids Rock is successful because ______.
A.it encourages kids to experience music
B.it helps kids learn from great musicians
C.it allows kids to decide how to learn music
D.it offers musical programs all over the country
小題4:What does the writer want to tell us?
A.Learning music is a good way to become successful.
B.Teaching in a proper way benefits students’ development.
C.It’s necessary for students to practice a lot in learning music.
D.It’s important for teachers to discover the new sides of students.

In America, most people don’t get enough sleep. Children aged 5 to 12 are advised to sleep 10 to 11 hours every night, but most of them can’t sleep that long. A study found that about 41 million American workers got less than six hours of sleep every night. Scientists worry that parents are passing their bad sleeping habits down to their children.
In the study, Reut Gruber and some other scientists either added or reduced on hour of sleep for healthy children aged 7 to 11. They watched the children for five nights. They wanted to know if the amount of sleep can affect a child’s behavior.
Before the study began, students were asked to sleep the same amount of hours as usual. Their teachers were asked to record their behavior. After five nights of the records, scientists found that those who slept one hour less behaved worse than those who slept one hour more. Students with less sleep were more likely to feel sad and had more problems paying attention.
The scientists chose to study children in their homes instead of in a laboratory, because they wanted to find out how everyday changes might affect children’s behavior at school. “In the study, nobody became a talent, and nobody became crazy. But small changes in children can really make a big difference,” says Gruber.
小題1: Scientists worry that_______ may cause children to sleep less.
A.too much homework
B.pressure from parents
C.TV and computer games
D.parents’ bad sleeping habits
小題2: Scientists did the new study in order to know_______.
A.why children can’t get enough sleep
B.how long children should sleep every night
C.what children like to do before they go to sleep
D.if the amount of sleep can affect a child’s behavior
小題3: Who helped do some new study, children with less sleep_______.
A.Teachers. B.Parents. C.Scientists. D.Psychologists.
小題4:According to the new study, children with less sleep_______.
A.were more likely to feel excited
B.were more active in playing games
C.had more problems paying attention
D.didn’t want to answer questions in class
小題5:The new study was done in_______.
A.a(chǎn) laboratory B.a(chǎn) classroom

There are many things you can do to improve your memory. Among them are many kinds of useful ways are well as taking special care of your health.
It is important that you make yourself excited to make your memory more active. You can do this by doing some new activities and by changing your daily habits. Learning a new skill helps your brain(大腦)to develop. When trying to remember something, you should pay special attention to the most important things about it .Do not allow other thoughts to enter your mind because this will reduce your chances of making right memories.
An excellent way to help memory is to connect information with pictures. Try to see the pictures in your mind. Taking notes and keeping a diary will also be helpful.
Healthy food and plenty of vitamins are necessary for your memory to work well. Drinking a lot of water also helps keep your memory. You must allow your brain to have enough sleep and rest. When you are asleep, your brain stores memory. Not enough sleep can cause problems with storing information .And being tired will also stop you from being able to think clearly and well.
In order to keep your mind on your work, you must be free from worry. Generally keeping fit and normal health checks are both important as well-not just for improving your memory.

In 1926, a Frenchman named Niepce needed pictures for his business. But he was not a good artist. So he invented a very simple camera. He put it in a window of his house and took a picture of his garden. That was the first photo. The next important date in the history of photography was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything clearly, even the smallest thing. This kind of photo was called a Daguerreotype(銀版照相). Soon other people began to use Daguerre’s way. Travelers brought back wonderful photos from all around the world. People took pictures of famous buildings, cities and mountains. In about 1840, photography was developed. Then photographers could take picture of people and moving things. That was not simple. The photographers had to carry a lot of film and other machines. But this did not stop them, for example, some in the US worked so hard. Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual because they were very lifelike(栩栩如生的). Photography also became one kind of art by the end of the 19th century.
