B After doing the self-assessment, Kitty is making a plan for studying English. Read her plan. Do you think she has some good ideas
I often speak English well in class, but I still need to practise more.
I need to work harder to learn new words and grammar rules. I plan to copy the new words in my notebook and read them every morning. I plan to remember five new words every day. Grammar rules are difficult, so I will keep an English diary and try to use the new grammar rules I have learnt. I plan to watch English TV programmes every weekend in order to improve my listening skills.

Unit 4 Life on Mars
A Life on another planet
Daniel wants to find out more about life in space in the future. He has found the following article by a famous scientist who thinks humans could live on Mars by the next century.
Moving to Mars
Some people believe that humans could live on the planet Mars by the year 2100. Our own planet, the Earth, is becoming more and more crowded and polluted because of the rapid increase in population. ① It is hoped that people could start all over again and build a better world on Mars. Here is what life there could be like.
be crowded with 挤满了……
有望……
温馨提示：此符号表示“考点精讲点拨”链接。
At present, our spacecraft are too slow to carry large numbers of passengers to Mars—it would take months. With the development of technology, by the year 2100, the journey might only take about 20 minutes in spacecraft that travel at the speed of light! ② However, the spacecraft would travel so fast that the journey to Mars might be quite uncomfortable. Many people would feel ill.
学科素养·勇于探究
激发好奇心和想象力，培养坚持不懈的探索精神。
反义词 comfortable
Humans cannot survive without water, oxygen or food. ③ So far, nobody knows whether there would be enough water or oxygen on Mars for people there. Moreover, scientists are not sure whether plants could grow on Mars. Food would most probably be in the form of pills and would not be so tasty. ④
Gravity could be another problem. The gravity on Mars is only about three-eighths of that on the Earth.
People would have to wear boots that are specially designed to prevent themselves from floating off into space. ⑤
Compared with life on the Earth, life on Mars would be better in some ways. ⑥ People would have more space. They might live in houses with huge comfortable rooms. Also, robots would do most of their work so that they could have more time to relax.
动词不定式（短语）作定语
There would probably be no schools on Mars. Every student would have a computer at home connected to an interplanetary network. They would study at online schools with “e-teachers”.
Life on Mars would be interesting as well as challenging.
