Sometime early in the next century, human beings will move to Mars（火星）．They will live there for about a year，and then will be replaced with another group of pioneers．Building he base on Mars will advance our knowledge of the solar system and aid in our under standing of the earth．
We already know that Mars resembles the earth in many aspects：general size，presence of water，length of day． range of temperatures．These resemblances have caused many people to consider a centuries’ long project：to terraform Mars．Terraforming means altering a planet’s surface so that Earth’s life forms can survive there．This concept，previously found only in science diction is now being seriously considered by scientists．
Terraforming Mars is theoretically simple：add nitrogen and oxygen to the atmosphere；pump water to the surface；and add the earth’s plants and animals in the order in which they developed on earth．But it will take at least 300 years．
Some people think that such a project is too huge for humans to undertake，but there are very good reasons to make the attempt．The earth now contains some 6 billion people and no one has any idea of how many humans the earth can support．Our very existence and numbers are threatening many other species．We also have had some experience with terraforming our own planet：altering the landscape，the atmosphere and the climate．Currently terraforming earth has become a wiser activity as we try to control global warming，air and water pollution，and preserve some natural living places．
While the possibility of such a project is small，it is not impossible．Even if earthbound societies come and go in the next 300 years，the project can continue through the work of the Mars settlers without the need for constant backing from the earth．
The future existence of all the people in our world may very well depend upon our ability to terraform Mars．
1．What would be the best title for this passage?
A．Terraforming Mars． B．Saving the Earth．
C．Travelling to Mars． D．A Newly found Place．
2．What does the underlined word“altering”mean in the second paragraph?
A．Warming B．Changing． C．Planting． D．building．
3．According to the passage the main purpose of terraforming Mars is to_____．
A．do some scientific research work
B．find out its similarity to earth
C．avoid the dying away of many other species
D．find on Mars living place for t he increasing human beings
4．The main reason for causing many people to consider terratormsng Mars is that _____．
A．there are some resemblances between Earth and Mars
B．terraforming Mars is theoretically simple
C．we have had some experience with terratorming our own planet：Earth
D．the development of science and technology is very rapid

| A. The power and habit of thinking B. The value of previous education C. The correctness in using mother tongue D. The development of an educated man E. The possession of gratitude F. Refined and natural manners |

The first characteristic of an educated man is the precision of the use of the native language. When one hears English well spoken, with pure diction, correct pronunciation, and an almost unconscious choice of the right word, he recognizes it at once. How much easier he finds it to imitate English of the other sort.

When manners are artificial and forced, no matter what their form, they are bad manners. When, however, they are the natural expression of fixed habits of thought and action, and when they reveal a refined and cultivated nature, they are good manners. There are certain things that gentlemen do not do, and they do not do them simply because they are bad manners.

Human beings for the most part live wholly on the surface or far beyond the present moment and that part of the future that is quickly to follow it. They do not read those works of prose and poetry which have become classic because they reveal power and habit of reflection and induce that power and habit in others. When one reflects long enough to ask the question how? He is on the way to knowing something about science.

An educated man continues to grow and develop from birth to his dying day. His interests expand, his contacts multiply, his knowledge increases, and his reflection becomes deeper and wider. It would appear to be true that not many human beings, even those who have had a school and college education, continue to grow after they are twenty-four or twenty-five years of age. By that time it is usual to settle down to life on a level of more or less contented intellectual interest and activity. The whole present-day movement for adult education is a systematic and definite attempt to keep human beings growing long after they have left school and college, and therefore, to help educate them.

The more visionary dreamer, however charming or however wise, lacks something that an education requires. The power to do may be exercised in any one of a thousand ways, but when it clearly shows itself, that is evidence that the period of discipline of study and of companionship with parents and teachers has not been in vain.
