Mr. and Mrs. March lived together with their four daughters. Amy was very shy. Beth loved being at home. Meg looked very pretty. Jo was tall and thin and she was a tomboy.. Their home was always busy and full of noise and people. Next to them lived old Mr. Laurence and his grandson, Laurie. They lived in a very large and comfortable house. But it was a house without life.

One day, Joe saw Laurie standing at an upstairs window in his house and looking down at their garden. Jo’s sisters were playing in the snow there. They were throwing snowballs and having a lot of fun. But Laurie’s face was very sad.

“Poor boy!” Jo thought. “He’s all alone. He needs some friends.” She couldn’t stop thinking about him. She wanted to go and see him, but how could she go to the house without an invitation?

Then one snowy afternoon, she saw Laurie’s grandpa go out. This gave her an idea. She took a broom from the kitchen.

“What are you going to do, Jo?” asked her sister Meg.

“To clear the garden path.” Answered Jo.

When Laurie saw Jo from the window, a big smile changed his pale, sad face.

Jo laughed and shouted, ”How are you? Are you ill?”

Laurie opened the window and said,” I’m better now, thank you. I had a bad cold and had to stay inside for a week”.

“I’m sorry,” said Jo. “Are you bored?”

“Yes, very.” he replied.

“Don’t your friends come to visit you?”

“No. But I don’t want to see anybody. Boys are noisy and they give me a headache.”

“Girls are quiet.”

“I don’t know any girls.”

“You know us.”

“That’s true! Can you come and visit me?” cried Laurie.

“ I’m not quiet, but I’d like to come,” replied Jo. “I must ask Mother first.” She ran back into her house.

A few minutes later, she returned and rang the bell on the door of laurie’s house. A servane took her upstairs.

“Here I am!” she said brightly. “Mother sends her love and my sisters gave me this blancmange (牛奶冻) for you.”

“That looks delicious,” Laurie said. He was very happy to see Jo.

Jo looked around. There were lots of books on the shelves.

“A nice room!” she said. “I can read to you if you like.”

“No, let’s talk,” replied Laurie.

“All right,” said Jo, “I can talk for hours. My sisters say I never know when to stop.”

“You have three sisters-Amy, Beth and Meg.” Laurie continued.

“How do you know this?” Jo was surprised.

“You call each other’s names when you are in the garden. Sometimes I can see you all around the table with your mother. She has a very kind face. I like looking at her. I haven’t got a mother.”

Jo felt sad when she heard this.

“Why don’t you come and visit us?” she said, “It isn’t good for you to stay in this house all the time.”

“Thank you. I’d like to come very much.” Said Laurie.

“We know all our neighbours except you.” Jo said, “ I’m glad we’re friends now.”

She told him about all the interesting things in her life. She said,” Besides(除了……之外) plays, I also love books.” Laurie loved books too, and offered to show her the library in the house. The library was a wonderful room. Jo loved it.

“Wow!” she said, “All those books!”

Laurie said, “A person needs more than books.”

in the sand were saying. He turned off the road to save them from being hurt.

Queen: I won’t fully believe it until I see and hear him myself, Amram.

Amram: Then why don’t you come to our country and pay him a visit, your Majesty?

You think it's "cool" to carry your backpacks and head out to school. But if you don't know exactly how to choose, load, lift and wear them-these all-important accessories（配件）can be a pain in the back. Not to mention the neck, head and shoulders.

Backpacks can influence your health. Carrying a heavy load improperly can lead to poor body position; and even hurt the spinal column(脊柱）This can cause muscle strain, headaches, back, neck and arm pain.

For example, if it is carried on one shoulder; a heavy backpack forces the muscles and spine to balance the unequal weight. This may increase the possible back problems later in life.

More than 50 percent of young people suffer back pain by their teenage years. Research shows that this could be mainly caused场improper use of backpacks.

Here's some advice to help you carry backpacks comfortably and safely.

Pick a pack that has two wide, adjustable, comfortable shoulder straps（带子）, along with a hip or waist strap, and plenty of pockets. Make sure the pack fits properly and its size is suitable for the wearer's body.

Packing it properly. Only put in the pack what is needed for that day. It's a good idea to know

what each object weighs. The total weight of the filled pack should be no more than 10 to 15 percent of the wearer's own body weight. Pack heaviest objects close to the body, and place little ones outside, away from the back.

Putting the backpack on. Put the pack on a smooth surface, at waist height. Put on the pack, one shoulder at a time, then adjust（调整）the straps to fit comfortably. Remember when lifting a backpack, or anything, to lift using the arms and legs and to bend at the knees.

The right way to wear a backpack. Both shoulder straps should be used, and adjusted so that the pack fits the body, without hanging to one side. Backpacks should never be worn over just one

shoulder. You should be able to move your hands between the backpack and your back. The waist strap should also be worn.

The human body is a machine that can raise lots of interesting questions. Why, for example, are yawns（呵欠）contagious（传染的）? What's up with ice-cream headaches? Here are answers to these and other questions about our bodies.

Why do I get a headache when I eat ice cream too quickly?

Scientists aren't exactly sure what causes the brain freeze when we eat ice cream or other super cold foods too quickly, though some believe it's the result of changed blood .flow in the nervous system. Blood vessels in the head tighten to stop the loss of body heat and then relax to let blood flow rise; that sudden rush of blood is what causes the headache. You can improve an ice-cream headache by rapidly rubbing your tongue across the roof of your mouth to help warm up things.

What causes my stomach to make a low continuous noise when I'm hungry?

Actually, your stomach makes noise whether you're hungry or full; you just hear it more clearly when you're hungry. Think of your digestive tract（消化道）as a really long tube lined with smooth muscle tissue. These muscles move food, fluids and gas through your digestive tract. ____

________________________. It can make you feel embarrassed尴尬的）but is nothing to worry about.

Why do I blush when I'm embarrassed?

When you're embarrassed, your brain releases a shot of adrenaline（肾上腺素）, which makes your heart race and blood vessels become larger in size. All this happens to increase blood flow and oxygen delivery throughout the body in a fight-or-flight reaction（对抗反应）. There are a lot of tiny blood vessels in your face, which turn noticeably redder from this sudden rush of blood. As for the actual function of blushing, researchers are still trying to find that one out.

Why are yawns contagious?

Have you ever yawned in front of someone, only to have them yawn right back? It's a common thing, but researchers don't have a good explanation for it. They do, however, know this happens only with humans and chimpanzees(黑猩猩）. A bigger question puzzling scientists is why we yawn at all. It used to be thought that yawning showed that oxygen to the brain was not enough, but that's just a myth. A growing body of research now shows that yawning is nature's way of keeping our brains cool.

42. What is the meaning of the underlined word tighten?

A. 变松 B. 变紧 C.变短 D. 变长

43. Which of the following sentences can be filled in the blank?

A. And that's what you're hearing when your stomach makes noise.

B. And that's why you're so hungry when your stomach is empty

C. And that's what makes you feel uncomfortable when you're full.

D. And that's how it makes a difference to your digestive tract.

44. Which of the following statements is TRUE?

A. There is no way for you to improve an ice-cream headache.

B. Researchers have found out the actual function of blushing.

C. Your stomach makes noise only when you are hungry.

D. Researchers don't have a good explanation for why yawns are contagious.

C. Some Useful Discoveries D. Our Amazing Feelings

The Garbage (垃圾) Project started at the University of Arizona in 1973. Since then, the students and teachers in it have studied the modern garbage in different cities.

To study the garbage, the students had to travel to landfills (填埋场) , the places where cities bury (填埋) their garbage. While the students were studying the garbage they wore special clothes. Students were very careful when they opened bags of garbage.

One important thing the students have learned from studying the garbage is that the garbage in landfills disappears very slowly. That was surprising to both the students and many scientists who had thought that about 70 % of the garbage in landfills would disappear quickly. Even in cities where it rains a lot, the students found newspapers from 1948, 40-year-old hot dogs, and vegetables from 1970. And the students also found many more empty bottles of cola than they expected.

How to dispose of our garbage well depends on what kind of garbage it is: regular(普通的) garbage, dangerous materials, or recyclable materials, such as newspapers and glass bottles. Regular garbage goes to regular landfills. Dangerous materials are harmful to people's health and the environment. They shouldn't go into regular landfills.

Homes are full of dangerous waste. One kind of the dangerous waste in homes is batteries. When batteries are buried directly（直接地）in a landfill, they often break open. The poison inside them moves through rain water to the bottom of the landfill. Then it can pollute the natural water in the ground.

Another dangerous waste from homes is motor oil. When people pour old motor oil on the ground or throw it in the garbage, it pollutes the environment.

Our garbage problem is not new, but as the world's population continues to grow, it will become a bigger and bigger problem.

C. mustn't be poured on the ground

D. never pollutes the environment

Every day there is less and less space on Earth for rubbish. Yet every day we make more and more rubbish. What can we do? We can recycle some of our rubbish. Recycling means that the rubbish will be made into something that can be used again.

Recycling helps Earth. And it saves space in rubbish dumps. Half of everything that we put into landfills could be recycled instead. In fact, most things made of paper, metal, glass and plastic can be recycled.

Paper can be broken into small pieces and made into new paper. Steel and aluminum cans（金属雄）can be melted down（熔化）and made into new cans. The same is true of glass bottles. This can be done aver and over again. Recycling doesn't take as much energy as making these things the first time. So we can use less of Earth's fuel resources.

Plastic can be melted down, too. Then it can be formed into park benches, playgrounds and so on. Some people call plastic the "wood" of the future. Things made of plastic will last about 400 years-even if they stay outside in the weather. No wood can do that!

27. The underlined word "landfills" in Paragraph 2 probably means _____________.

A. bench factories B. places for rubbish

C. green mountains D. recycling centres

"Why do I live? Why do I wish for anything, or do anything? Is there anything in my life that will not be destroyed by my death?" Like Leo Tolstoy, the famous Russian writer, many people ask these difficult questions. Tolstoy spent his whole life trying to answer these difficult questions.

As a young man, he thought people could achieve perfection if they tried hard enough. So he worked very hard to be the best in everything. He thought that he would find meaning and truth in success.

In 1850s. Tolstoy wrote his first stories. He wrote about his life in the army. He also told stories about his childhood. These works were published and Tolstoy became a well-known writer.

He earned the respect he always wanted. Many rich and smart men met and talked with Tolstoy. Some of them were writers like him. They talked a lot about faith ( 信仰) and the meaning of life. But soon Tolstoy recognized that these men were not perfect. Now he knew they could not answer his questions about faith.

So in the 1860s, Tolstoy tried a different way to find the meaning of life. He opened a school for the children of his serfs-the people who worked on his land. These workers were very poor. He wanted to help them because he thought they were more honest than the rich people he knew.

Tolstoy learned a lot from his workers. He understood how they worked hard to support their

families. He began to believe that marriage and family would give his life meaning. So in 1862, Leo Tolstoy married a young woman named Sonya Behrs.

The next 15 years were the best years of Tolstoy's life. It was during this time that he wrote his most famous books-War and Peace and Anna Karenina. Many experts say that War and Peace is one of the greatest books ever written. In these books, Tolstoy believed humans should live a simple life and take care of their families. Tolstoy thought this would satisfy him and bring him happiness.

Leo Tolstoy is still a very respected writer today. His faith and writings have influenced many

people all over the world.

41. Which is the correct order of the following events?

My father was a cemetery（公墓）keeper.When I was a child，he often took me there.Before we left each time，he would lay some stones on some graves（坟墓）.I never asked why.I just thought that was his work.

Yesterday, I visited my sick father. He asked me to go to the cemetery and lay some stones. For some reason, it had to be done that day. I agreed. I hadn't been there for a long time.

When I got there, I found a woman in front of one of the graves I would lay a stone on.As I bent to lay it, I heard her whisper“ Thank you”. It was then that I noticed the date of death on the grave was that same day. The grave was that of a child, only five when he died fifteen years ago.

" He's my son, "she said. " But, where’s your father? He was always the one to leave the stone.”

Your father is the kind of man who would ease the pain of a mother’s heart though we are strangers. Just tell him you saw me today, won’t you?” She said.

Trees in cities "live fast but die young" compared to forests in the countryside, warns a new study.

Researchers found that trees in cities die younger than ones in the countryside because of the higher levels of CO2. City-living trees suffer(遭受) a loss of carbon storage(碳储量). That means trees produce less energy from the air.

Now researchers say more must be done to deal with the situation. Ian Smith, a PhD student of Boston University in the United States, said, “Cities are in the important position in fighting against rising temperatures and increasing CO2.”. “We find that tree planting alone may not be enough to keep and increase city canopy cover(树冠覆盖率). Because of the age and size of the present canopy, efforts to improve and protect tree health are badly needed for increasing city tree cover and canopy cover.”

The research team used a model to watch changes among street trees for several planting and management methods. Researchers also used the model to watch tree growth, death and planting rates(率)both among trees in Boston city and forests in the countryside in Massachusetts.

It was discovered that rates of carbon cycling and growth rates among city trees were nearly four times faster than those in the countryside. However, loss of carbon storage and death rates are also higher, especially death rates are more than double higher than those in countryside forests.

The study, published in PLOS ONE, has reminded scientists to encourage communities to do more to plant and protect trees. It is important to increase city canopy cover and carbon storage.
