Passage One
A lot of people are their own enemies (敌人). They regard themselves as unlikely to succeed in college and often feel that there have been no accomplishments (成就) in their lives. In my first year of college especially, I saw people get themselves down all too quickly. There were two students in my class who failed the first test and seemed to give up immediately. From that day on, they walked into the classroom carrying defeat(失败)on their shoulders the way other students carried textbooks under their arms. Both students hang on until about mid-term. When they disappeared for good, no one took much notice, for they had already disappeared in spirit(精神)after that first test.
They are not the only people in whom I have seen the self-doubt do its work. I have really wanted to shake them by the shoulders and say: “You are not dead. Be proud and pleased that you have brought yourself here to college. Be someone. Breathe. Hope. Act.” Such people should not use self-doubts as an excuse for not trying. They should pull themselves together and get to work. They should start taking notes in class and trying to learn. Above all, they should not give up without even trying.

1. The phrase “get themselves down” (Para. 1, line 4) probably means_________.
A. tell lies B. lose confidence
C. avoid dangers D. waste time
2. When the two students dropped out, no one took much notice because________.
A. they had long lost heart in class performance
B. they were absent from class too often
C. they didn’t get on well with other students
D. they were so much cut off from the rest of the class
3. According to the passage, the two students failed in their study because of their ________.
A. shyness  B. proudness C. self-doubt D. laziness
4. The author thinks that the two students should________.
A. give up their college education
B. learn from other students
C. feel happy because they are in college
D. try hard before giving up
5. The sentence “Both students hang on until about mid-term” (Para. 1) tells us that________.
A. they didn’t study well
B. they didn’t take part in class activities
C. they didn’t take notes in class
D. they didn’t finish their study that term

Passage Two
Economically,the world can be divided into two parts.The difference between them is that one part is poor and the other is wealthy. In the poor countries of the world, a lot of people never get enough to eat. In wealthy countries, a lot of people eat too much. The tragedy is that there are more people in the poor countries than there are in the wealthy countries. It is estimated that approximately 80% of the world’s population cannot afford to have proper food, housing or medical care.
The poorer countries are often refferred to as the Third World. They have special problems. Often their land is too poor to grow anything on. The land can be improved, but a lot of things have to be done first. New farming methods have to be introduced, people have to be educated and reliable sources of water and energy have to be found.
Many of these problems are too complex for one country to solve alone. Outside help is needed, but it has to be the right kind of help. Money is not enough. Newly developed countries need to be helped to be able to help themselves.

1. According to the article, what is the tragedy?
A)There are more wealthy countries in the world
B) There are more poor countries in the world
C) There are more wealthy people in the wealthy country
D) There are more poor people than wealthy people in the world

A)new farming method to be introduced B) people to be educated
C) reliable sources of water and energy to be supplied D) a better living conditions are to be accommodated
4. What would the right kind of help be,in the author’s opinion?
A) The wealthy people should give them money
B) The developed countries should teach them the ability needed for self-help
C) The wealthy people should send over the technicians to help install the
sophisticated machines
D) The learned man should establish some shops over there
5. The last word of this passage“themselves”means .
