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.  【小题1】 
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.
 【小题2】  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.  【小题3】  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.
 【小题4】 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.  【小题5】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.

A new term has begun. Teachers are   1  about the fact that new students are not easy to deal with(对付). They like to bring telephones（手机） and MP3 players to school. What is   2  , some students even use telephones to do out-of-class matters in class, or sometimes just for fun.

Mrs Kirk first began thinking about students’ manners six years ago. “I had my first class in which students were sleeping or talking to each other. It seemed that learning well had nothing to do with them.” she says. “At first, I got worried about this.” but then I said to myself, “You’re giving   6  , and you need to deal with this kind of situation (情况). These students need to know more about manners. It’s time to help them develop some good   7  . They shouldn’t waste time doing nothing when they are young. Sooner or later, they may regret(后悔) the time they have wasted.”
Mrs Kirk also   8  a list of suggestions(建议) to help teachers better manage (控制) their classes. The following are among her suggestions:
l     On the first day of class, tell students how they will benefit(受益) by taking the class and the importance   9  listening carefully in class.
l     Do not allow（允许） them to bring telephones or MP3 players to the class at all.

Be a potato, but be the best
A young college student thought that he chose the wrong major (专业) at a common college, so he drank every day and didn’t study at all. He b  1   more and more discouraged.
But he was never a  2   from Professor Yang’s biology (生物) class. He liked the course. Besides, Yang’s class was so i  3   that he always listened carefully, never caring about w  4   the other students were paying attention or not in class.
Once he put a note in the homework he handed in, saying: “Professor, it is said that today’s college students are c  5   than potatoes. Do you agree?”
That day Professor Yang sent for him after class. When he came, he f  6  the professor at a table with food on it. They drank happily over their meal.
When they became half drunk, the professor took out a small potato that was sprouting (发芽的). “Do you know how much this c  7 ?” he asked the young man. “It’s soft but poisonous. N  8  will take it even if it’s free. ” He then threw the potato away.
The professor then showed him another potato. It was half the s  9  of a football and perfectly round. “This potato is organic (有机的). It is not only large and fresh but also free of pollution. People are in need of such k  10   of potatoes and they’re quite expensive.”
The young man was impressed by what he’d heard. “Be such a potato,” said the professor.
