Mercury is the smallest member of the sun's family. It is only 3.100 miles across. It is also the sun's swiftest planet. Its yearly journey round the sun is only 85 days.

            Mercury always keeps one side towards the sun. On this side it is always day, on the other side always night. We only see the lighted side.

            Mercury appears to us like a yellowish orange star. The nearest planet to the sun, it is always seen near the sun, either just before sunrise or soon after sunset. People sometimes call mercury the morning star or evening star.

           Mercury is half the size of the earth. Because it is much lighter, it has much less gravity. If you can visit Mercury in a spaceship, you will find it a strange world. Its low gravity makes you feel very light. If your weight on earth is 100 pounds, your weight on Mercury is only 27 pounds. Looking at the sun from Mercury, you can see that it's much more brilliant than it is seen from the earth. And the yellow centre of the sun appears three times bigger from Mercury.

           On its lighted side, Mercury's temperature is about 300 degrees centigrate. But the dark side is extremely cold, but 150 degrees below zero so mercury is probably the coldest as well as the hottest of the planets.

21. A. Mercury is .......

     A. the sun's fastest planet                 B. the coldest planet        

     C. the hottest planet                          D. all are correct

22. We cannot see the dark side of Mercury because .......

     A. it moves very fast.             

     B. it always appears just before sunrise or soon after sunset.

     C. it always keeps one side towards the sun.                               

     D. it is too far for us to see.

23. When can we see Mercury? - We can see it ......

     A. just before the sunset     

     B. just before sunrise      

     C. after the sunset   

     D. both A and C are correct

24. Why do we weigh much on the earth than on Mercury? - Because .......

      A. Mercury is nearer to the sun.               B. Mercury has got less gravity than the earth.

      C. Mercury is much hotter.                       D. none are correct.

25. Why does the sun look bigger when it is seen from Mercury?

 - Because .......

       A. Mercury is the smallest planet of the sun.       

       B. Mercury is nearer to the sun.

       C. Mercury is a light planet.                            

       D. It only takes Mercury 88 days to move round the sun.

VI, Read the passage and circle the best option A, B, C or D to complete the following questions or
statements:
The Sun today is a yellow dwarf star. It is fueled by thermonuclear reactions near its center that convert
hydrogen to helium. The Sun has existed in its present state for about four billion six hundred million years
and is thousands of times larger than the Earth. By studying other stars, astronomers can predict what the
rest of the Sun’s life will be like. About five billion years from now, the core of the Sun will shrink and
become hotter. The surface temperature will fall. The higher temperature of the center will increase the rate
of thermonuclear reactions. The outer regions of the Sun will expand approximately 35 million miles, about
the distance to Mercury, which is the closest planet to the Sun. The Sun will then be a red giant star.
Temperatures on the Earth will become too high for life to exist. Once the Sun has used up its
thermonuclear energy as a red giant, it will begin to shrink. After it shrinks to the size of the Earth, it will
become a white dwarf star. The Sun may throw off huge amounts of gases in violent eruptions called nova

explosions as it changes from a red giant to a white dwarf. After billions of years as a white dwarf, the Sun
will have used up all its fuel and will have lost its heat. Such a star is called a black dwarf. After the Sun
has become a black dwarf, the Earth will be dark and cold. If any atmosphere remains there, it will have
frozen over the Earth’s surface.
66. It can be inferred from the passage that the Sun ______.
A. is approximately halfway through its life as a yellow dwarf
B. will continue to be a yellow dwarf for another 10 billion years
C. has been in existence for 10 billion years
D. is rapidly changing in size and brightness
67. What will probably be the first stage of change for the Sun to become a red giant?
A. Its surface will become hotter and shrink.
B. It will throw off huge amounts of gases.
C. Its central part will grow smaller and hotter.
D. Its core will cool off and use less fuel.

Otherwise Pluto will become too far from Earth and it will be more difficult to get near the planet. The New Horizons mission is important because no spacecraft has ever been sent that far before. The information collected during this mission will help to explain what the outer edges of the solar system look like and how the solar system was formed 4.5 billion years ago. * NASA: National Aeronautics and Space Administration * the Solar System: the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, IJranus, Neptune, Pluto

Dear Oanh,

Thank you very much for your letter which arrived a few days ago. It was lovely to hear from you. I am sorry, I haven’t written for you such along time because I studied hard to pass the final exam. However, I had agreat weekend more than every when I went to live concerts last night with my friends. Now, I am writing to tell you how the wonderful concert is.

It is the beautiful concert I have ever taken part in with many people and the miracle of sound of piano. As you know, my pianist is Yiruma and in last concert I couldn’t believe that he appeared in my eyes and gave me a big hug after his performance. I also listen a soothing music which is played by him and other professional musicians. Only when I heard his song from the stage I feel anythings around me seem to disappear and I can fly with many stars on the sky to forget all my fears which I suffered before.

That is amazing.

Let’s come back to my live concert. It is so cool and until now I can’t forget my feeling about it. Do you often to go live concerts? What kind of music do you like listening to? Who is your favourite singer?

I am glad if you tell me about it in the next letter

I look forward to your reply

Your sincerely

Exercise 2: We had dinner at a new restaurant yesterday

Dear Oanh,

Thank you very much for your letter which arrived a few days ago. It was lovely to hear from you.

I think the restaurant which you told me in the letter is very interesting. I also like to eat out and I usually go to a restaurant for dinner with my family tiwce a month. Our favourite restaurant is a traditional restaurant in Hang Bong street. It is not big but it is always busy. There are only afew tables in the restaurant and on each table is a vase with lovely flowers. There are plants in the room corners. I usually order the traditional dishes and eat them with rice. For example, fish cooked with sauce, spring roll,…and vegetable and so on. The food is deliciuous so we enjoy it very much. The service is also quick and frienfdly . My family always have pleasant evening at our favourite restaurant.

Shall we go there when you come to visit my family next time?

See you next time.

Kính gửi, Oanh

Cảm ơn bạn rất nhiều vì lá thư của bạn đã đến một vài ngày trước. Thật đáng yêu khi nghe từ bạn. Tôi xin lỗi, tôi đã viết cho bạn như vậy trong suốt thời gian qua vì tôi đã học tập chăm chỉ để vượt qua kỳ thi cuối cùng. Tuy nhiên, tôi đã có những ngày cuối tuần sôi động hơn mọi khi tôi đến buổi hòa nhạc trực tiếp tối qua với bạn bè. Bây giờ, tôi đang viết để cho bạn biết buổi hòa nhạc tuyệt vời như thế nào.

Đó là buổi hòa nhạc tuyệt vời mà tôi từng tham gia với nhiều người và sự kỳ diệu của âm thanh piano. Như bạn đã biết, nghệ sĩ piano của tôi là Yiruma và trong buổi hòa nhạc cuối cùng, tôi không thể tin rằng anh ấy xuất hiện trong mắt tôi và ôm tôi rất nhiều sau màn trình diễn của anh ấy. Tôi cũng nghe một bản nhạc êm dịu được chơi bởi anh ấy và các nhạc sĩ chuyên nghiệp khác. Chỉ khi tôi nghe bài hát của anh ấy từ sân khấu, tôi cảm thấy mọi thứ xung quanh mình dường như biến mất và tôi có thể bay với nhiều ngôi sao trên bầu trời để quên đi tất cả những nỗi sợ hãi mà tôi phải chịu đựng trước đây.

Thật là tuyệt vời.

Hãy để trở lại buổi hòa nhạc trực tiếp của tôi. Nó thật tuyệt và đến tận bây giờ tôi mới có thể quên cảm giác của mình về nó. Bạn có thường xuyên đi đến buổi hòa nhạc trực tiếp? Bạn thích nghe loại nhạc nào? Ai là ca sĩ yêu thích của bạn?

Tôi rất vui nếu bạn nói với tôi về nó trong bức thư tiếp theo

Tôi mong được trả lời của bạn

Thân ái

2. Chúng tôi đã ăn tối tại một nhà hàng mới ngày hôm qua

Kính gửi,

Cảm ơn bạn rất nhiều vì lá thư của bạn đã đến một vài ngày trước. Thật đáng yêu khi nghe từ bạn.

Tôi nghĩ rằng nhà hàng mà bạn nói với tôi trong thư rất thú vị. Tôi cũng thích đi ăn ngoài và tôi thường đến nhà hàng ăn tối với gia đình tôi một tháng. Nhà hàng yêu thích của chúng tôi là một nhà hàng truyền thống ở phố Hàng Bông. Nó không lớn nhưng luôn bận rộn. Chỉ có một bàn trong nhà hàng và trên mỗi bàn là một bình hoa với những bông hoa xinh xắn. Có cây trong góc phòng. Tôi thường gọi các món ăn truyền thống và ăn với cơm. Ví dụ, cá nấu với nước sốt, chả giò, cuốn và rau và vân vân. Thức ăn rất ngon nên chúng tôi rất thích nó. Dịch vụ này cũng nhanh chóng và frienfdly. Gia đình tôi luôn có buổi tối vui vẻ tại nhà hàng yêu thích của chúng tôi.

Chúng ta sẽ đến đó khi bạn đến thăm gia đình tôi lần sau chứ?

Hẹn gặp lại lần sau

You should call the police when you believe a crime is about to be committed or has been comitted. Cops would much rather hear from people BEFORE the crime than after the crime. For example, if you see a person you don't recognize as a neighbor, in your neighborhood looking into parked cars, call the cops. We would rather try to catch him and identify him before he steals the car, rather than have to chase him (endangering lives) after he steals it.You should also call the cops about disturbing...

You should call the police when you believe a crime is about to be committed or has been comitted. Cops would much rather hear from people BEFORE the crime than after the crime. For example, if you see a person you don't recognize as a neighbor, in your neighborhood looking into parked cars, call the cops. We would rather try to catch him and identify him before he steals the car, rather than have to chase him (endangering lives) after he steals it.

You should also call the cops about disturbing choices people make that can effect your quality of life. If someone puts their stereo on so loud it bothers you, you should go ask him to turn it down, and if he doesn't then call the cops. If there is a loud party next door and they keep waking you up, call the cops to make them turn down the noise or break up the party. Call in if you have drug dealing or prostitution in your neighborhood. You should not have to put up with that crap.

There are many ways to get your local cops to help you, that is what they are there for, you dont necessarily have to call. If it is an ongoing problem a letter or email to the chief will usually get the ball going. Or you can wave down an officer and tell them what the problem is, they are public servants that work for the citizens. A lot of serious crimes have been solved because a citizen passed along information to an officer.
