A. There will probably be no school on Mars.
B. It might take us two or three days to get to Mars.
C. There is a problem for us to live on Mars.
D. Food will not be the same.
E. First, people will have more space.

    Many people believe that, by the year 2100, we will live on the planet Mars(火星). Here is what life could be like.
    First of all, transport should be much better. By 2100, spaceship can travel at half the speed of light. 
    Secondly, humans need food, water and air to live. Scientists should be able to find plants that can grow on Mars. These plants will provide us with food and air.
 We could easily jump too high and fly slowly away into space. To prevent this, humans on Mars have to wear special shoes to make themselves heavier.
    Life on Mars will be better in many ways.  It is possible to live in a large building with many bedrooms. Then, robot will do most of the work, so we have more time for hobbies.
 Every student can study, do their homework on the computer and take exams in online schools. Each student will also have their own online teacher called “e-teacher”.
    However, in some ways, life on Mars may not be better than that on the earth today.   Meals will probably be in the shape of pills(药片) and will not be as delicious as they are today. Also, space travel will make many people feel ill.

   It was Monday. Mrs. Smith's dog was hungry, but there was not any meat in the house. So Mrs. Smith took a piece of paper, and wrote the following words on it: “Give my dog half a pound of meat.” Then she gave the paper to her dog, “T{#blank#}1{#/blank#} this to the butcher(屠夫) and he's going to give you your lunch today.”

    Holding the piece of paper in its m{#blank#}2{#/blank#}, the dog ran to the butcher's. It gave the paper to the butcher. The butcher read it  c{#blank#}3{#/blank#} and knew that it was really the lady's handwriting, so he gave the dog some meat. The dog was very happy, and a{#blank#}4{#/blank#} the meat up at once.

    The next day, the dog came to the shop again. It gave the butcher a piece of paper again. A{#blank#}5{#/blank#}reading it, he gave it half a pound of meat once more.

    On the t{#blank#}6{#/blank#} day, the dog came with a piece of paper again. This time, the butcher d{#blank#}7{#/blank#} take a look at paper, and gave the dog its meat.     

But the dog came again at four o'clock. And the same thing happened once again. To the butcher's more s{#blank#}8{#/blank#}, it came for the third time at six o'clock with a third piece of paper.

He said to himself, “This is a small dog. W{#blank#}9{#/blank#} does Mrs. Smith give it so much meat to eat today?”

    Looking at the piece of paper, he found that there were not any words on it! How would he f{#blank#}10{#/blank#} after knowing about this? Can you guess?
