How much sleep do we need? We are all different. Some people need only three hours of sleep a night. Others need ten hours of sleep a night. Most Americans sleep an average (平均) of seven to eight hours a night. After the age of fifty, the average sleeping time goes down to 6.5 hours a night.
Most people have a bad night when they can’t fall asleep (入睡). The name of this problem is called insomnia.
This isn’t a new problem. Many famous people in history had insomnia, too. Some of these people had special ideas to make them sleep. Benjamin Franklin, the famous inventor, had four beds. He moved(移動) from one to another to fall asleep. King Louis XI V (國王路易十四) of France had four hundred and thirteen beds and hoped to fall asleep in one of them. Mark Twain, the famous American writer, had a different way. He lay on his side across the end of his bed.

試題分析：本文講述我們需要多少時間的睡眠，很多人會患有失眠癥很多名人也不例外。
小題1:C細節理解題。根據第一段提到After the age of fifty, the average sleeping time goes down to 6.5 hours a night.可知50之后每晚睡6.5個小時。故選C項。
小題2:B 細節理解題。根據第三段中提到King Louis XI V (國王路易十四) of France had four hundred and thirteen beds and hoped to fall asleep in one of them他是法國人可得知A錯誤。根據第三段提到Many famous people in history had insomnia, too.許多名人也會失眠故B項正確。Benjamin Franklin, the famous inventor, had four beds. He moved(移動) from one to another to fall asleep.他是個著名的發明家，而不是作家，故C項錯誤。根據第一段提到Benjamin Franklin, the famous inventor, had four beds. He moved(移動) from one to another to fall asleep.50歲以后才會睡眠6.5小時故D項錯誤。
小題3:A 細節推斷題。根據最后一段提到King Louis XI V (國王路易十四) of France had four hundred and thirteen beds and hoped to fall asleep in one of them他有四百三十多張床，希望能在某張床上快速睡著。.故選A項。
小題4:C 猜測詞意。根據第二段Most people have a bad night when they can’t fall asleep (入睡). The name of this problem is called insomnia 許多人晚上不睡不著，這個問題的名字叫失眠，故選C項。
小題5:B 段落大意。第一段首先通過發問的形式提到我們需要多少的睡眠，這是不同的，有的人長有的人短，美國人平均7個小時，而等待50歲后是6.5個小時，可知在講我們需要多少時間睡眠。故B項符合題意。
考點:健康類閱讀。

It may seem easy to say that plants and animals are different. Any child can tell the difference between a tree and a dog. But those differences are far deeper than just what they look like. The cells (細胞) that plants are made up of are different. In other words, the cell wall of plants has something special.

First of all, it's important to find that not all plant cells have a cell wall. Besides, there are many differences of a cell wall based on the kinds of plant. The following is meant to be what a plant cell wall is like.
The cell wall of a plant is on the outside of the cell membrane (膜). It is usually hard and cannot be bent easily, but the degree of flexibility (韌性) of the cell wall is different. It is based on the special use that the cell has in keeping the plant alive. Cells that make up the trunk of a tree are clearly less flexible than cells on a leaf.
Cell walls act in many ways. They serve to protect the plant. They provide support, as well as help in the movement of chemicals and wastes into and out of the cell. More importantly, they control the water that goes in and out. Plants must have good water controlling systems (系統), allowing them to keep water during dry seasons, and get rid of unnecessary water. Plants can't walk around to find water, so being able to control water is very important.
So there you have it , what a plant cell wall is. Of course, there are many other things that are not talked about here. Knowing more about plant cell wails requires further study and research.
小題1:From the first two paragraphs we can find that _____.

A．all plants have a ceil wall

B．plant cells and animal cells are the same

C．different kinds of plant have different cell walls

D．there are no differences between the cells of a tree and a dog

小題2:The underlined word "bent" in the passage is the closest in meaning to _____.

A．變形的

B．防水的

C．太陽灼傷的

D．表皮破損的

小題3:Cells in the trunk of a tree are _____ those on a leaf.

A．as flexible as	B．not so flexible as
C．more important than	D．less important than

小題4:What is the most important use of a plant cell wall?

A．To protect the plant.	B．To provide support.
C．To move chemicals and wastes.	D．To control the water.

Maybe you know floods, earthquakes, sandstorms and so on. But have you heard of typhoons?
Typhoons are some of the worst storms, usually around the Pacific Ocean and the South China Sea. Most happen in July, August and September.
How does a typhoon happen? When lots of sea water gets hot in the summer sun, it evaporates （蒸發）into the air. This makes the air hotter. When the air gets warm enough, it starts to move higher up into sky. Then cooler air around it rushes in. It fills the space that is left. After the air gets warmer, it starts to move quickly, making wind. The wind goes in circles（圓圈）and it keeps moving higher in the sky. The warmer the air gets, the quicker the wind moves. And when the wind moves faster than 30 metres a second, a typhoon begins.
A typhoon has two parts, one is called the “eye”. In the eye, the wind does not move so fast. The other part is the wall of clouds around the eye. Here are the strongest winds and hardest rains.
Typhoons are very dangerous. In November this year, Typhoon Haiyan killed 5500 people in Philippines. More people are missing.
What to do when a typhoon hits?
Stay inside. Close all the windows and stay away from them.
Try to bring all of your things inside. Strong winds could even blow away your bikes!
Listen to the radio or TV for important information.
If you’re told to go to a safer place, do it right now.

A．an advertisement of a typhoon	B．a travel record

a. The wind moves fast enough, a typhoon starts.
b. The air moves quickly, making wind.
c. The sun makes sea water hot.

B．c-d-b-a

C．c-d-a-b

London used to be “foggy” for the same reason that cities like Beijing or Chongqing are “foggy” today．The “fog” was in fact smog, a mixture of smoke and fog．In other words, it was made by air pollution．In London, some of this pollution came from factories, but much of it came from the coal(煤)that people burnt in their houses to keep warm during the winter．By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air．A new law was made and nobody could burn coal in any British city．Within a few years, the air became much cleaner．There were no more “pea-soupers”．
Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago．However, this problem is more difficult for Chinese cities to solve．One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses．If these factories were closed, this would harm the economy and lots of people would lose their jobs．Another reason is that changing from coal to cleaner fuel(燃料), like gas, is quite expensive．
However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution．As a result, there are fewer “pea-soupers”in Beijing than there used to be．
小題1:What was the main reason for air pollution in London?

A．There was too much smoke in the sky．

B．There were too many factories in the city．

C．People burnt too much coal in the houses．

D．The city was too big for the cleaners to clean．

小題2:How did the air in London become much cleaner?

The World's Largest Insect
This giant insect can be used as a toy. A child ties one end of a string to a stick and the other end around the "neck" of an insect. Holding the stick, the child lets the insect go. With a loud whirring sound, the insect takes off, pulling the string in a large curve over the child's head. The child laughs as the stick jumps around. The child is African, and the toy is the African Goliath beetle, the largest insect in the world.
The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel.
African children often use the Goliath beetle as a toy. Although it is over 15 centimeters long, it is quite harmless.

English is very important in the modern world. Many people want to learn it well. Here are some things that I want to say about learning it.
To learn English well, you need two things－passion and good learning methods (方法). Passion is the more important one. Why? Because passion makes you want to learn English. Learning methods only tell you how to learn it better and faster.

It was a village in India. The people were poor but they were happy. After all, their forefathers had lived in the same way for centuries.
Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.
This seemed like money for nothing. There were millions of frogs in the fields around, and they were useless to the villagers. What they had to do was to catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. The villagers were able to dream of a better future. But the dream didn’t last long.
The change was hardly noticed at first, but it seemed as if the crops weren’t doing so well. More worry was that the children fell ill more often, and there were more insects around lately. The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (殺劑) and medicine. Soon there was no money left.
The people realized what was happening. It was the frog. They hadn’t been useless. They had been doing an important job--- eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.
Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.
小題1:From Paragraph l, we learn that the villagers_______.

A．worked very hard for centuries

B．dreamed of having a better life

C．were poor but somewhat happy

D．lived a different life from their forefathers

小題2:Why did the villagers agree to sell frogs?

A．The frogs were easy money.

B．They needed money to buy medicine.

C．They wanted to please the visitors.

D．The frogs made too much noise.

小題3: What might be the cause of the children’s sickness?

A．The crops didn’t do well.	B．There were too many insects.
C．The visitors brought in diseases.	D．The pesticides were overused.

小題4:What is meaning of the last sentence of the article?

A．Happiness comes from peaceful life in the country.
