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.

    Have you ever wondered what an American high school and its students are really like?

    A typical (典型的) American high school has several large buildings and enough s{#blank#}1{#/blank#} for about 1,500 students. Every student is given a locker. When students first arrive at school, they go straight to their lockers to put away or get their textbooks and to hang up their outdoor clothes. As American textbooks are e{#blank#}2{#/blank#}, students would rather borrow than buy them. Students must pay back if they lose any of them.

    American students have different types of school t{#blank#}3{#/blank#}. They usually take a yellow school bus or walk to school if they live close enough. Sometimes their parents drive them to school. When they turn 16 years of age, most take a free driving class at school for one term. If students earn passing grades in the class and also pass their state driver's exam, they can begin driving t{#blank#}4{#/blank#} to school.

    Each day, students take six or seven classes. They must take science, maths, English and social studies. They can choose art, homemaking, fashion design and other classes. In some schools students are required to take one or more of the following special classes: health education, physical education or foreign language studies. Students m{#blank#}5{#/blank#} to different classrooms for each subject. This is because each teacher has their own classroom. There is a short break between classes, to give the students the time to hurry to their next class.

    The r{#blank#}6{#/blank#} school day usually ends early in the afternoon. After school more than half of the students are busy going for after-school activities. These activities include sports―especially football, basketball, baseball and soccer or c{#blank#}7{#/blank#}, such as yearbook, speech, school newspaper, photograph or student government. Students feel relaxed and pleased when they take part in them.
