Passage Three
At the first sight the planet Mars does not appear very welcome to any kind of life.It has very little oxygen and water, the temperature at night is below ?50℃ and winds of 100 miles per hour cause severe dust storms.However, the surface of the planet seems to show that water flowed across it some time in the past, and it is believed that there is enough ice at the poles to cover the planet with water if it melts.Although there is no life on the Mars now, some scientists think that there may have been some form of life long time ago.At that time, the planet had active volcanoes; the atmosphere was thicker and warmer; and there was water.In fact, in some ways the Mars may have been similar to the Earth, where life exists.
Some people believe that the Mars could support life in the future if the right conditions were produced.The first step would be to warm the planet using certain gases which trap the Sun’s heat in the planet’s atmosphere.With warmth, water and carbon dioxide(二氧化碳)， simple plants could begin to grow.These plants could slowly make the Mars more suitable for living.It is estimated that the whole process might take between 100,000 and 200,000 years.In the meantime, people could begin to live on the planet in special closed environments.They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.

Passage Four
It is physically impossible for a well?educated intellectual, or a brave man to make money the chief object of his thoughts; as physically impossible as it is for him to make his dinner the principal object of them.All healthy people like their dinner, but their dinner is not the main object of their lives.So all healthy?minded people like making money—ought to like it and to enjoy the satisfaction of winning it; but the main object of their lives is not money; it is something better than money.
A good soldier, for instance, mainly wishes to do his fighting well.He is glad of his pay—very properly so, and just complains when you keep him ten months without it; still, his main opinion of life is to win battles, not to be paid for winning them.
So of doctors.They like fees no doubt—ought to like them; yet if they are brave and well educated, the entire object of their lives is not fees.They would rather cure their patients and lose their fees than kill him and get it.And so with all other brave and rightly trained men; their work is first, their fees second, very important always, but still second.
