There are many colors in nature. But do you know if a color has weight? I think you’ll say “no”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment.
First, put two objects with the same weight into two boxes. Then cover the box. Third, wrap one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.
Why do you think so? A scientist found that different colors have different weight in a man’s mind. So he did many tests and at last he got the result. That is to say, every color has its own weight in our mind and their order is the same. The heaviest color is red, then blue, green, orange, yellow and white.
The scientist told us that colors also have smell. Can you smell the color? Of course not. Then why did the scientist say so? That is because every color stands for a kind of light with a certain wavelength. It reaches our brain through sense organs.
According to this discovery, scientists say that people accept the colors they like, and refuse the colors they hate. So your body and mind will be healthy by using the colors you like. Or you’ll be nervous or even get ill. For example, if you stay in a room with red windows, wallpapers and furniture for two hours, you’ll feel you have been there for four hours. But if the room is blue,  you’ll feel you have been there for only an hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change with different colors.
小題1:The purpose of the second paragraph is to tell us ___________.
A．a(chǎn) red box is heavier than a white one
B．a(chǎn) color has weight in one’s mind
C．white paper is lighter than red paper
D．you can know the weight of a color by holding it
小題2:Why did the scientist say colors have smell?
A．Because people can sense the light from colors.
B．Because we can smell colors with our nose.
C．Because every color has its own sweet smell.
D．Because every color can give off light of the same length.
小題3:It can be implied from the text that ___________.
A．colors have orders in weight
B．colors can change the weight of an object
C．people would stay longer in a room with red windows
D．colors can affect our mood and health
小題4:This passage is probably a ___________.
A．book reviewB．fiction novelC．fairy taleD．science report

小題1:B
小題2:A
小題3:D
小題4:D

試題分析：這是一篇科普讀物。顏色真的有輕重、有氣味嗎？科學家解釋說人們感覺顏色有輕重是因為我們的思維定式而已，人們感覺顏色有氣味是因為每種顏色代表一種有特定波長的光而已；但人們可以接受自己喜歡的顏色，充分利用自己喜歡的顏色。
小題1:細節(jié)理解題。第二段話介紹你用一個小實驗來感受顏色的重量，但現(xiàn)實生活中顏色是沒有輕重的，只是我們自己的感覺而已；而且在第三段中也說到顏色只是在我們的思維中有了輕重。所以應該選B。
小題2:細節(jié)理解題。短文第四段說到：That is because every color stands for a kind of light with a certain wavelength. It reaches our brain through sense organs.那是因為每一種顏色代表一種有一定波長的光，它經(jīng)過感覺器官到達我們的大腦。所以應選A。
小題3:細節(jié)理解題。這個題目可以用排除的方法來做。很顯然A、B是不正確的，從最后一段可以看出人在紅顏色的房間會感覺時間長了，這也是感覺而已。所以A、B、C都要排除，只能選D。
小題4:細節(jié)理解題。短文多次提到科學家發(fā)現(xiàn)顏色有輕重、顏色有味道，所以這是一篇科普小短文。故選D。

No one knows exactly how many disabled people there are in the world, but the number may be over 450 million. The number of disabled people in India alone is probably more than double the total population of Canada.
In the United Kingdom, about one in ten people have some disability. Disability is not just something that happens to other people. As we get older, many of us will become less mobile (可動的) , hard of hearing or have failing eyesight.
Disablement can take many forms and happen at any time of life. Some people are born with disabilities. Many others become disabled as they get older. There are many progressive disabling diseases. The longer time goes on, the worse they become. Some people are disabled in accidents. Many others may have disability in the form of a mental illness. All are affected by people’s attitude(態(tài)度) towards them.
　　Disabled people face many physical barriers(障礙). Next time you go shopping or to work or visit friends, imagine what would you do if you could not get up steps, or on to buses and trains. What would you do if you could not see where you were going or could not hear the traffic? But there are other barriers: prejudice(偏見)can be even harder to break down and ignorance (無知) represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully understand what the disabled go through, so it is important to draw attention to these barriers and show that it is the individual person(個人) and their ability, not their disability, which counts.
小題1:The first paragraph points out that ___________.
A．it is possible to get an exact number of the world’s disabled people
B．there are many disabled people in the world
C．the number of disabled people in India is the greatest
D．India has not much more disabled people than Canada
小題2:The key word in Paragraph 4 is ___________.
A．barriers B．disabledC．disability D．prejudice
小題3: Which of the following statements is NOT true according to the passage?
A．There are about 10 percent disabled persons in the UK.
B．The whole society should pay more attention to the barriers faced by the disabled people.
C．Even the able-bodied may lose some of their body functions when they get older.
D．There is still prejudice against the disabled which results mainly from ignorance.
小題4:It can be concluded（推斷）from the passage that ___________.
A．we should try our best to prevent disablement
B．we must take a proper attitude towards the disabled
C．the able-bodied people will never fully understand the disabled
D．both physical and mental barriers are hard to break down

Bananas don’t grow on trees. They grow on a stalk that looks just a little like a stalk of corn. The stalk is soft enough to be cut with a knife.

It takes about a year before bananas are ready to be picked. Some are as small as fingers. Others are as long as men’s arms. Some banana plants grow as tall as a house – even taller!
Not all bananas are eaten as fruit. Some never get sweet, and they are cooked as a kind of vegetable.
People in most countries never see a banana until it reaches the store. But if you visited a country where it’s hot and rains a lot all the year, you might see a banana plantation, a large farm where bananas grow.
The tasty fruit doesn’t come from a seed but from a root planted deep in the ground. First a stalk pushes up into the air. The leaves grow. In the beginning the banana plant grows very fast – sometimes as much as the length of your feet in one night. Soon, sweet-smelling flowers come out, and when their flowers drop off, bananas begin to grow.
As they get bigger, bananas start turning up. It looks as if they’re growing upside down! Bananas are ready to eat when they turn soft and yellow. Bananas are picked long before this – when they’re hard and green. This is because bananas have to travel many miles before they arrive at a store. On trucks and boats and trains bananas travel all over the world. There are special boats just for bananas and special trains that keep them just cool enough so that they will get ripe while traveling. If bananas are picked when they are ripe (成熟的), they will spoil on the way.
小題1:What’s the weather like in places where bananas grow?
A．Dry and coldB．Cold and wetC．Wet and hotD．Hot and dry
小題2:The fruit of banana plants come from________.
A．a(chǎn) stalkB．a(chǎn) treeC．a(chǎn) seedD． a root
小題3:Bananas are picked long before they are _____________.
A．greenB．ripeC．hardD．red
小題4:Which of the following is NOT true according to the passage?
A．All bananas are eaten as fruit.
B．Some banana plants grow taller than a house.
C．Bananas get ripe on their way to the store.
D．It takes about a year before bananas are ready to be picked.

One morning, Wu Li discovered that her classroom had changed. She found that the desks were no longer in rows(排), but pushed together to make eight bigger desks. She was too excited about it for the first two days and she couldn’t listen to the teachers carefully. But soon she and her classmates got used to this new classroom arrangement (安排). “Now our class is quieter,” said Wu. “What’s more, we can come up with our own ideas and learn more through discussion. It’s a better way to study.”
Li Yu liked it, too. He said, “Group members first discuss, and then show ourselves in front of the whole class. It makes us believe in ourselves.” It was part of a reform (改革) at Li’s school—Baita Secondary School. The school made this reform because they wanted to provide students with easier ways to study and more chances to discuss. “Our school hopes it can improve students’ abilities (能力) to study by themselves and work in groups,” said Zhang Yong, the principal of the school.
However, the reform has demanded (要求) more from teachers. Now they have only about 15 minutes to give the lesson which should be taught in 45 minutes before. It is difficult to teach in such a short time. The teachers have to find better ways to teach more effectively.
“The reform demands more, but I’m sure it is helpful,” added Mr Zhang.
小題1:After the new classroom arrangement it was easier for Wu Li and her classmates to ______ in class.
A．discuss with each otherB．sit in the classroom
C．push desks togetherD．teach a lesson

“How can I learn English well?” This is a question many students ask. In my opinion, the most effective way is to learn lessons by heart. If you can recite the text and write it out, you’ve learned it fairly well. And if you can tell, in your own words, what the lesson says you’re a very successful learner indeed. Your English will be quite perfect.
This is a difficult task. However, if you try to learn by heart only part of each lesson, you’ll find it not half so hard as you might have thought.
Learning this way, you will make rapid progress. Of course, writing is also necessary. It helps you a lot on our way to success in English.
Equally important is to feel the language. You should be able to laugh at jokes and be shocked at bad news. When using English, try to forget your mother tongue. Instead of helping you, your own language gets in your way. So, never try to see English through translation.
小題1:In the writer’s opinion, the most effective way in learning English is ________.
A．to practise speaking, writing and feeling it
B．to forget your own native language
C．to translate everything into his own language
D．to memorize the English words and grammatical rules
小題2:“Instead of helping you, your own language gets in your way.”This sentence means that memorizing your own language can ________.
A．help you to study English well
B．stop you mastering English
C．make English easy to learn
D．help you notice mistakes
小題3:Equally important is to feel the language. “to feel the language” here means________.
A．to get a knowledge of English by touching
B．to be able to read and write English
C．to translate English into your own by imagining
D．to be able to experience the rich sensation of the language
