  In the United States, boys and girls start school when they are five years old. In some states they must stay in school until they are sixteen. Most students are seventeen or eighteen years old when they graduate from secondary school. Another name for secondary school is high school.

  Most children go to public elementary (初小) and secondary school. The parents of public school pupils do not have to pay directly (直接地) for their children's education because tax (稅)money supports the public schools. If a child attends a private (私立) school, his parents pay the school for the child's education.

  Today about half of the high school graduates go on to colleges and universities. Some colleges and universities receive tax money from the governments. A student at a state university does not have to pay very much if his parents live in that state. Private colleges and universities are expensive. However, almost half of the colleges students in the United States work while they are studying. When a student's family isn't rich, he has to earn money for part of his college expenses.

閱讀理解:

  Several years ago, my parents, my wife, my son and I ate at one of those restaurants where the menu is written on a blackboard.After a wonderful dinner, the waiter set the check in the middle of the table.That’s when it happened:my father did not reach for the check.

  Conversation continued.Finally I realized that I should pick up the check!After hundreds of restaurant meals with my parents, after a lifetime of thinking of my father as the one with dollars, it had all changed.I reached for the check, and my view of myself suddenly changed.I was an adult.I was no longer a kid.

  Some people mark off(區(qū)分)their lives in years, I measure mine in small events.I didn’t become a young man at a particular age, like 16, but rather when a kid who wandered in the streets called me “mister.” These events in my life are called “milestones”(里程碑)

  There have been other milestones.The cops(policemen)of my youth always seemed big, even huge, and of course they were older than I was.Then one day they were suddenly realized that all the football players in the game I was watching were younger than I was.They were just big kids.With that milestone gone was the dream that someday, maybe I, too, could be a football player.Without ever having reached the hill, I was over it.

  I never thought that I would fall asleep in front of the TV set as my father did.Now it’s what I do best.I never thought that I would go to the beach and not swim, yet I spent all of August at the shore and never once went into the ocean.I never thought that I would appreciate opera, but now the combination of voice and orchestra attract me.I never thought that I would prefer to stay home in the evenings, but now I find myself passing up parties.I used to think that people who watched birds were strange, but this summer I fond myself watching them, and maybe I’ll get a book on the subject.I feel a strong desire for a religious belief that I never thought I’d want, feel close to my ancestors(祖先)long gone, and echo my father in arguments with my son.I still lose…

  One day I bought a house.One day-what a day!–I became a father, and not too long after that I picked up the check for my own father.I thought then it was a milestone for me.One day, when I was a little older, I realized it was one for him, too, another milestone.

閱讀理解:

  Our boat floated on, between walls of forest too thick to allow us a view of the land we were passing through, though we knew from the map that our river must from time to time be passing through chains of hills which crossed the jungle plains.Nowhere did we find a place where we could have landed:where the jungle did not actually spread right down into the river, banks of soft mud prevented us going ashore.In any case, what would we have sailed by landing?The country was full of snakes and other dangerous creatures, and the jungle was so thick that one would be able to advance only slowly, cutting one’s way with knives the whole way.So we stayed in the boat, hoping we reached the sea, a friendly fisherman would pick us up and take us to civilization.

  We lived on fish, caught with home-made net of string(we had no hooks), and fruits and nuts we could pick up out of the water.As we had no fire, we had to eat everything, including the fish, raw I had never tasted raw fish before, and I must say I did not much enjoy the experience; perhaps sea fish which do not live in the mud are less tasteless.After eating my raw fish, I lay back and dreamed of such things as fried chicken and rice, and ice-cream.In the never-ending damp heat of the jungle, ice-cream was a particularly frequent dream.

  As for water, there was a choice:we could drink the muddy river water, or die of thirst.We drank the water.Men who had just escaped what had appeared to be certain death lose all worries about such small things as diseases caused by dirty water.In fact, none of us suffered from any illness as a result.

  One day we passed another village, but fortunately nobody saw us.We did not wish to risk being taken prisoners a second time:we might not be so lucky to escape in a stolen boat again.

(1)

What they could see in the boat was only ________.

[  ]

A.

high wall

B.

villagers from time to time

C.

vast land

heavy woods

A.

the mud on the shore was too soft

B.

the forest was too thick to let them go through

C.

they could not find the mark on the map

D.

they could not find anyone to lead them out of the forest

(3)

The passage infers that the forest was ________.

[  ]

A.

rich of fruits and animals to be served as food

B.

not very thick as they could advance slowly by cutting the branches

C.

full of various dangerous beings

D.

full of ancient trees

(4)

Escape
