　　Light travels at a speed which is about a million times faster than the speed of sound. In a second, light travels about 300,000km, but sound travels only 340m. You can get some ideas of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke come from his gun before the sound reaches your ears.

　　This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reach you. The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 20 million km, per minute. In some cases, the light from one of tonight's stars started on its journey to you before you were born.

　　Thus, if we want to be honest, we can not say,“the stars are shining tonight.”We have to say,“The stars look pretty. They were shining four years ago but their light has only just reached the earth.”

Light travels at a speed which is about a million times faster than the speed of sound. You can get some idea of this difference by watching the start of a race. If you stand some distance(距离) away from the starter, you can see smoke from his gun before the sound reaches your ears.

This great speed of light produces some strange facts. Sunlight(太阳光) takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light that you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km. per minute. In some cases, the light from one of tonight’s stars had started on its journey to you before you were born.

Thus, if we want to be honest, we can’t say, “The stars are shining tonight.” We have to say instead, “The stars look pretty. They were shining four years ago, but their light has only just reached the earth.”

It's very early in the morning and I'm sitting outside. It's also very cold and dark. With me is Jim Nightingale, and he is the reason I'm up so early. He passes me a hot cup of coffee. "Not long to wait now," he says. I hope he's right.

After a few minutes there is a very weak light in the east, and then I hear a bird singing. It sings very loud and very clear. "That's the robin(知更鸟)," says Jim. A few more birds start singing with the robin and Jim knows the names of them too. Half an hour later, there are more and more birds singing, and it's very loud! Suddenly, all around us the air is full of the sound of birdsong. This is the dawn chorus(晨鸣), and it's beautiful.

"Wow, this is amazing!" I tell Jim, who is smiling. "Is there a dawn chorus every morning?"

"Birds can sing any time of the year but the best time is the end of winter and during the spring. This is when the birds sing most."

"Really? So, why do they sing?" I ask.

"Well, there are two reasons," explains Jim. "Most of the songbirds who sing are males. They want to find a female(雌性)so they sing to show how strong they are. The females listen and choose the best singer! The birds also sing to tell other males to go away. They need their own area; they don't like sharing with another male."

I listen to the birds; the songs seem too much to me. "Do the birds sing a special song in the morning?"

"That's a good question," replied Jim. "The successful birds have many kinds of calls and songs. Sometimes they copy the songs of other birds. This makes it sound like there are many birds in that place already and other males stay away. Also the female likes songs with different notes. Some birds, for example the European wren, have songs that contain over 700 different notes per minute!"

So, how does Jim know so much about birds? Well, he works as a volunteer for the Royal Society for the Protection of Birds. He is trying to help the birds live in the modern world. "More and more of the birds' habitat disappears every year. The sparrow, for example, was a very common bird in the UK, now it's in danger."

By now the sun is up and the birds are quiet. It's light so they can start looking for food, they need a big breakfast after all that singing.

1.Why does the writer get up early in the morning?

A. To visit her friend. B. To drink hot coffee.

C. To see different birds. D. To hear birds sing.

2.A bird sings early in the morning mainly_______.

A. to call a female's attention B. to fight with other males

C. to find a place to live in D. to start looking for food

3. According to the text, which of the following statements is true?

A. At first the writer is happy to be up so early in the morning.

B. Male birds have their own ways of fooling other birds.

C. It's easier for the birds to find food early in the morning.

D. Jim has a job with the Royal Society for the Proteciton of Birds.

4.The text is mainly about_______.

A. the robin's songs B. the birds' habitat

Here are some American classroom customs:

If the teacher asks a question, you are expected to give an answer. If you do not understand the question, you should put up your hand and ask the teacher to repeat the question. If you do not know the answer, it is all right to tell the teacher that you do not know. Then he or she knows what you need to learn.

There is no excuse for not doing your homework. If you are absent (缺席), you should ear your teacher or someone who is in your class and ask for the assignment(作业). It is your responsibility (责任) to find out what assignments you have missed. It is not the teacher's responsibility to remind you of missed assignments.

You must not be absent on a test day. If you are seriously ill, call and let the teacher, know you will not he there for the test. If your teacher allows make - up tests, you should take the test within one or two days after returning to class. Serious illness is the only reason for missing a test.

Be on time! It is considered(认为) rude to be late. Also, it disturbs other students. If you must come in late, be sure to do it quietly. Have your books and papers out of your bag before you come into the room. Then go to your seat and sit quietly. In the U. S. it is not necessary to knock before you enter the classroom. If you must leave during class, do so quietly. There is no need to ask the teacher's per-mission. Entering a teacher's office or any office with a closed door without knocking fast is not accept-able. Knock first, then wait to he invited in.

Wearing a hat in class is considered impolite by many teachers. Some teachers may ignore it, but you should ask permission first.

1. What should a student do if he or she doesn't understand the teacher' s question?

___________________________________________________________________

2. If a student misses a class, how can he or she find out the assignment?

___________________________________________________________________

3. What is the only reason for missing a test?

___________________________________________________________________

4. Is it necessary for a student to knock before he or she enters the classroom ?

___________________________________________________________________

5. What about wearing a hat in class?

请阅读下面关于杭州几个博物馆的简介及几位游客的相关信息，并按要求匹配信息，为他们选择合适的博物馆。（改编）

56. Mike is from Great Britain. He has often heard of the amazing silk which is worldwide famous. He hopes to get some more information about it.

57. Surry is a person who is very interested in the West Lake because of its fantastic sights and amazing historic stories. He expects to get more details about the spotlight.

58. Jeffery is from Italy, he shows great interest in tea, especially Hangzhou Longjing as well as Chinese traditional buildings and houses. If it’s possible he’d like to have a cup of tea there.

59. Nicholas is a Junior middle school student who is in favor of wild lives, especially the ones live on wetlands, their living conditions and threats to them that influence their lives.

60. Anderson is a college student who shows love to history. He would like to pay a visit to the museum which can inform him a lot about periods of Zhejiang history.

A	B
There are several exhibition halls in this maze of a complex. The main gallery offers a brief look at several periods of Zhejiang history up to the Communist Revolution. Check out the gallery of Hangzhou native Chang Shuhong at the east end of the complex.	Every holiday, there’re crowds of people who enter China's Wetland Museum in Hangzhou, capital of east China's Zhejiang Province. The museum receives an average of nearly 5,000 visitors per day in this summer vacation, 2010. With the exhibition area of 7,800 square meters, it consists of four wetland-themed exhibition halls.
C	D
It’s not the best of museum Hangzhou has to offer, since it’s not as new as others, but in its thirty years of existence, the Tea Museum has seen quite a few improvements. The Exhibition Hall is the main attraction and takes you through the development of tea throughout the dynasties. There are teahouses for you to go into a real hike and a real home-style meal.	Anything that there is to be known about West Lake can be found out here: flora, fauna, aquatic life, culture and the influence of the famed waters. The museum is easy to miss from the backside. Walk around the front to the main entrance. But don't try to climb to the top of the grassy hill that covers the structure, or one of the numerous (be of great number) guards might take you out.
E	F
Here you can learn how silk is made, from the worm to bathrobe, then to silk. They've even got a large gallery of looms and several of them in use just to show how it's been done for centuries. After you're finished with the exhibits, check out the shopping area – at least here you can be confident that it's the real deal.	The West Lake Expo started in 1927, and though it was not held for 75 years, it is now back to its former glory. This centrally located museum houses many pictures of Hangzhou before Liberation and also tracks those who started it all. Nowadays with the popularity of the West Lake Expo, the museum has won more and more attention.
