A study finds that not enough morning light causes teenagers not to get enough sleep at night. “As teenagers spend more time indoors, they miss necessary morning light. Day light is needed to keep the balance of the body’s 24-hour biological system (生物系統(tǒng)), which regulates (調(diào)節(jié)) body temperature and sleep styles,” reports Dr. Mariana Figueiro. “These teenagers who receive little morning light are going to bed later, getting less sleep and doing badly in tests. They are more likely to fail in their exams.”
In the study, Dr. Figueiro asked 11 students in Grade 8 to wear special glasses to prevent blue morning light from reaching their eyes. At the end of the 5-day study she found that they fell asleep 30 minutes later than usual.
Throughout her research, Dr. Figueiro has been very worried about teenagers going to bed too late. The problem is that today’s schools require teenagers to be in school very early in the morning. These students are likely to miss the morning light because they often go to school before the sun is up or as it’s just rising.
Furthermore (此外), the schools are not likely to provide enough electric light to keep the balance of this biological system. Our biological system is much more sensitive (敏感的) to blue light. Therefore, having lots of light in the classroom does not make sure that there is enough light to keep our biological system balanced.

    Which of the following is the result of the study?

    1. A.
      Blue light in the morning harms the biological system.

  2. 2.

    1. A.
      has the same effects as afternoon light
    2. B.
      may change studying habits of teenagers
    3. C.
      is important to children’s biological system
    4. D.
      has no effect on students’ tests
  3. 3.

    What’s the problem of the students according to the study?

    1. A.
      There are not enough electric lights in the classroom.
    2. B.
      Being in school early affects their study habits.
    3. C.
      They have to go to bed very early to have enough sleep.

Have you ever wondered why birds sing? Maybe you thought that they were just happy.  After all,you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However,they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a 'territory' is? A territory is an area that an animal,usually the male,claims(聲稱)as its own. Only he and his family are welcome there. No other families of the same kind are welcome. Your garden and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten(威脅)you,you might shout. Probably this would be enough to frighten him away.
If so,you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time,especially at nesting(筑巢)season. So he is screaming all the time,whether he can see an outsider or not. This screaming is what we call a bird's song,and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs..
You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.
【小題1】 Some scientists believe that most of the time bird's singing is actually _______.
A.a(chǎn)way of warningB.a(chǎn)n expression of happiness
C.a(chǎn)n expression of angerD.a(chǎn)way of greeting
【小題2】What is a bird's "territory"?.
A.A place where families of other kinds are not accepted.
B.A place where a bird may shut at the top of its voice
C.An area for which birds fight against each other.
D.An area which a bird considers to be its own.
【小題3】 Why do birds keep on singing at nesting season?
A.Because they want to invite more friends.
B.Because they want to find outsiders around.
C.Because their singing helps frighten outsiders away.
D.Because their singing helps remove their fears.
【小題4】How does the writer explain bird's singing?
A.By comparing birds with human beings.B.By reporting experiment results.
C.By describing birds' daily life.D.By telling a bird's story.

Are you an only-child in your family? Are you feeling alone at home? How are you dealing with it?
Zhang Luwen, 12, feels lucky to have a 4-year-old “brother”. “With him, I never feel lonely at home. He goes with me wherever I go,” said the girl of Sichuan Province. But it is not easy to be a sister. Zhang has to help her parents bath her “brother” every week. This is because he is hairy — he is a dog.
As the number of pet owners in China grows more and more, Chinese students have animal friends at home. Experts say that these small animals give these only-children lessons in love, care, teamwork and generosity.
This month, the first study on the influence of pets on the children came out. It is a survey of 402 Beijing primary school students. It shows that animal friends are good for children.
China had more than 90 million only-children by 2006, according to the government. “In families of three, most children feel lonely. They don’t have many chances to learn how to love and be responsible for others,” said Zhou Xia in the study group. “So having a pet can help with the problem.”
However, some students complain that their parents don’t allow them to have pets. “They are afraid a pet would stop me studying,” said Chen Qi, of Chongqing.
Perhaps he could learn from Qin Yixing, 13, of Beijing. “I don’t play with my dog until I have finished my homework. I made the promise to my mom and I must keep it,” said the girl.
【小題1】According to the passage, experts think _______.

A.it is good for students to have animal friends at home
B.only-children families in China will be fewer and fewer
C.small animals at home are bad for students
D.parents should buy more pet animals for their children
【小題2】What can we learn from the passage?
A.Zhang Luwen’s parents bath every week.
B.Zhou Xia thinks a pet animal can solve the problem that children feel lonely.
C.Chen Qi of Chongqing has got a pet animal.
D.Qin Yixing’s parents don’t want her to have a pet.
