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. 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.

a. Hours.
b. Months.
c. Years.
3. What would the flight to Mars be like by the year 2100
a. Fast and comfortable.
b. Fast but uncomfortable.
c. Slow but comfortable.

B4 Daniel is making a list of the differences between life on the Earth today and life on Mars in 2100. Help him complete his list. Use the information from the article on pages 52 and 53.
Life on the Earth today Life on Mars in 2100
It is polluted and crowded. It would be clean and have lots of space.
Spacecraft are slow.
There is enough water and oxygen.
It would be clean and have lots of space.
Spacecraft would travel at the speed of light.

Disadvantages of life on Mars
Advantages of life on Mars
Conclusion
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! However, the spacecraft would travel so fast that the journey to Mars might be quite uncomfortable. Many people would feel ill.
Humans cannot survive without water, oxygen or food. 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.
Life on the Earth today Life on Mars in 2100
There are many kinds of tasty food.
Gravity is not a problem for us.
Many people live in small flats.
There would not be enough water or oxygen.
Food would most probably be in the form of pills and would not be so tasty.
The gravity is only about three-eighths of that on the Earth.
Life on the Earth today Life on Mars in 2100
People have little time to relax.
Students study at real schools.
People could have more time to relax.
Students would study at online schools with “e-teachers”.

gravity
The gravity on Mars is only about three－eighths of that on the Earth. 火星上的重力仅是地球上重力的八分之三。
◎用法总结:
three－eighths 八分之三。英语中分数的表达方法是:分子在前，分母在后；分子用基数词，分母用序数词；当分子大于1时，分母(序数词)后加－s。如:
六分之一one－sixth；十分之七 seven－tenths
另外，二分之一还可以用half表达；四分之一还可以用one quarter表达；四分之三还可以表达为three quarters等。
根据汉语提示填写单词。

1. Compared with life on the Earth, life on Mars would be better in some ways. 与在地球上的生活相比, 火星上的生活在有些方面将会更好些。
过去分词短语compared with life on the Earth在句中作状语。compare with … 意思是“ 与……做比较”， 此时with和to可通用。
e.g. This road is quite busy compared with ours.
与我们的那条路相比，这条路繁忙得多。
