You can not see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in our direction. So moon light is only second hand sunlight.
When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.
Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380 000 kilometers away, in only a little more than a second.

Education is not an end but a means to an end．In other words, we do not educate children only for the purpose of educating them．Our purpose is to fit them for life．
In some modern countries, it has for some time been fashionable to think that by free education for all one can solve all the problems of society and build a perfect nation．But we have already seen that free education for all is not enough; we find in some countries a far larger number of people with university degrees．They refuse to do what they think “low” work and, in fact, work with hands is thought to be dirty and shameful in such countries．But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of professor．We can live without education, but we die if we have no food．If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases．
In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in certain ways．Firstly each of us can do whatever work suited to our brains and ability．Secondly, we should realize that all jobs are necessary to society．It is very bad to be shamed of one’s work．Only such a type of education can be considered valuable to society．

| D．we shouldn’t think of work with hands as low work． |
| A．A large number of people can go to university． |
| B．Everyone can solve all the problems of society． |
| C．All the people can get free education． |
| D．Everyone must be educated differently to fit them for society． |
| A．Our society needs all kinds of jobs． |
| B．Free education for all is enough． |
| C．A farmer is more important than a professor． |
| D．People with university degrees shouldn’t do low work． |
On the first day of the 11th grade, our new math teacher Mr Washington asked me to go to the blackboard to do a math problem. I told him that I couldn’t do it. He asked, “Why not?” I paused, and then I said, “Because I’m educable mentally retarded (可教育智能迟滞).”
He came from behind his desk and looked at me. “Don’t ever say that again. Someone’s opinion of you does not have to become your reality,” he said.
It was a very special moment for me. Doctors said that I was educable mentally retarded in the fifth grade, and I was put back into the fourth grade. When I was in the eighth grade, I failed again.
But Mr Washington changed my life. This person always gave students the feeling that he had high expectations of them, and then all of the students did their best to live up to what those expectations were. He often said, “You have greatness within you.”
One day, I caught up with him in the parking place and said, “Mr Washington, is there greatness within me, sir?”
He said, “Yes, Mr Brown.”
“But what about the fact that I failed English, math, and history? What about that, sir? I’m slower than most kids.”
“It doesn’t matter. It just means that you have to work harder. Your grades don’t determine who you are or what you can produce in your life.”
“I want to buy my mother a house.”
“It is possible, Mr Brown. You can do that.” And he turned to walk away.
“Mr Washington?”
“What do you want now?”
“Uh, I’m the one, sir. One day you’re going to hear my name. I’m the one, sir.”
School was a real struggle for me. Mr Washington put many demands on me. He made me believe that I could do it. At the end of that year, I was on the honor roll for the first time in my life.
Years later, I produced five programs on public television. When one of my programs was shown on the educational television channel, I had some friends call him. I was sitting by the phone waiting when he called me. He said, “May I speak to Mr Brown, please?”
“Oh, Mr Washington, is that you?”
“Yes, it’s me. You were the one, weren’t you?”
“Yes, sir, I was.”
小题1:What does Mr Washington mean by saying “Someone’s opinion of you does not have to become your reality”?
| A．You needn’t have the same opinion as others. |
| B．You should believe what other people say. |
| C．What other people say about you may not be correct. |
| D．The doctor made a mistake. |
| A．He entered a good university. | B．He earned much honor. |
| C．He got a good job. | D．He made television programs. |
| A．people shouldn’t believe what doctors say |
| B．no one can be successful with hard work and confidence |
| C．no one is really educable mentally retarded |
| D．a good teacher can change a student’s life |
| A．Don’t believe others | B．I am the one |
| C．My best teacher | D．I succeeded at last |
As an effect of the high fuel prices spent on bus transportation, some American schools are changing to a four-day week. That means longer days instead of the traditional Monday through Friday schedule.
Having been approved for three years and beginning in the fall, students in the Maccray school district in Minnesota will be in school from Tuesday to Friday. Each school day will be 65 minutes longer. Officials say the district expects to save about sixty-five thousand dollars a year in transportation costs.
In new Mexico, the first school district changed to a four-day week in 1974 because of the Arab oil boycott(抵制). Now, 17 out of 89 districts use it.
In Custer, South Dakota, students have been going to school four days a week since 1995. Superintendent Tim Creal says the change has saved about one million dollars over just the past eight years. He sees other benefits, too. Students get more instructional time, and activities that used to take up class time are now held on non-school days. He says that in the future, the growth of online classes could make it possible to require even fewer days in school. High fuel prices are driving college students to take more online classes.
A four-day school week sounds like a great idea for students and teachers, but working parents may have to pay for child care for that fifth day.
小题1:According to Tim Creal, what makes it possible to have even fewer days in school?
| A．The increasing number of private tutors.(私人教师) |
| B．The development of teaching methods. |
| C．The increase in the number of online classes. |
| D．The growth in the income of Americans. |
| A．students will be in school from Monday to Tuesday. |
| B．four-day week was first carried out in South Dakota. |
| C．Maccray will save one million dollars every year. |
| D．Minnesota state has approved the four-day week plan |
| A．some school’s four-day week plan | B．districts using a four-day week. |
| C．how to save on transportation fees. | D．expense of school transportation. |

What happens inside the skull of a soccer player when repeatedly heads a soccer ball? That question motivated a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players, and some anxiety among those of us with soccer-playing children.
For the study, researchers at the Albert Einstein College of Medicine in New York selected 34 adults, men and women. All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions (脑震荡) in the past.
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned, using a complicated new M.R.I. technique which can find structural changes in the brain that can’t be seen during most scans.
According to the data they presented at Radiological Society of North America meeting last month, the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball fewer times.
This pattern of white matter loss is “similar to those seen in traumatic (外伤的) brain injury”, like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.
The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them, forgetting or fumbling the words far more often than players who had headed the ball less.
小题1:The passage is most probably a ________.
| A．news report | B．research report |
| C．story for soccer players | D．text for doctors |
| A．Computerized test | B．Questionnaire |
| C．Scanning | D．M.R.I. technique |
| A．significant effect on brain | B．little effect on one’s brain |
| C．nothing to do with the brain injury | D．one’s memory improved |
| A．Playing soccer frequently | B．Tests of their memory |
| C．White matter loss | D．Information processing |
| A．remembering | B．misunderstanding | C．recalling | D．missing |
