    Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times. Most of the people shown in these works were right-handed, so the scientists guessed that right-handedness had always been common through history. Today, only about 10% to 15% of the world's population are left-handed.

Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The left-side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.

No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. ①If a person does not receive the gene (基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.

Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today ②they don't have to.

    A strange thing happens to nearly everybody. At night, people turn off the lights, pull up the covers and close their eyes. Six or seven sleeping hours later, they wake up again. Strange, isn't it?

Sleep ①puzzles science. Scientists and doctors would rather talk about why one can't fall asleep. They are not sure what causes sleep. The best conditions for sleep are good health and meal neither too big nor too small. No worries and a comfortable place are important, too.

Strange things happen during sleep. For example, you move often. You would feel tired if you didn't. You also dream. Part of your brain is still awake when you sleep. Dreaming happens when the memory and imagination in parts of your brain are still awake. Experiments have shown most of us dream in color. Bad dreams may be caused by stomachache. Don't worry if you dream. Some great stories and poems were begun while their writers slept.

    For 72 years, Lisa Gumpel kept a secret. "For a long time, I decided not to tell anyone about it," said Gumpel, 85 years old, who finally settled (定居) in Minnesota 1. the war and now lives in the Twin Cities.

Their rescuer(营救者)was a British businessman named Nicholas Winton, who also kept the story to 4.(he) until his wife found a list of the 5.(children) names.

Gumpel was very surprised in 1988 when the truth about Winton's one-man rescue operation finally came out. "6.(someone) knew that he actually did all by himself," she said. "He 7.(work) so hard to save lives."

Winton still doesn't think he's a hero, saying that his life was never 8. danger and that he was doing what he feels every person should do.

A party was held for him and the people he had saved. Gumpel was 9.(excite) when she finally met him. "He still treats us all like we're his kids," she said with a 10.(warm) smile on the face.

    It was a quiet village in which there was a camp. It was far from the towns and cities and there were some high mountains around. Of course it was a good place for training the new soldiers. 1.. Mr. White, an officer of forty, was strict with them and he hardly let them leave the camp.

Of course they found the officer was angry.

And the other seven soldiers said they were late for the same reasons. It was the last soldier's turn. He said, "I'm sorry sir, I got on a bus on time, but..."

    Louis Armstrong had two famous nicknames (绰号). Some people called him Bagamo. They said his mouth looked like a large bag. Musicians often called him Pops, as a sign of respect for his influence on the world of music.

Although born in 1901 in New Orleans, poor, he lived among great musicians. Jazz was invented in the city a few years before his birth. Armstrong often said, "Jazz and I grew up together."

Armstrong showed a great talent for music when he was taught to play the comet (短号) at a boys' home. In his late teens, Armstrong began to live the life of a musician. He played in parades, clubs, and on the steamboats that traveled on the Mississippi River. At that time, New Orleans was famous for the new music of jazz and was home to many great musicians. Armstrong learned from the older musicians and soon became as famous as them.

In 1922 he went to Chicago. There, the tale (传说) of Louis Armstrong begins. From then until the end of his life, Armstrong was celebrated and loved wherever he went.

His comet playing had deep humanity (仁爱) and warmth that caused many listeners to say, "Listening to Pops just makes you feel good all over." He was the father of the jazz style and also one of the best-known and most admired people in the world. His death, on July 6, 1971, was headline news around the world.

    When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.

People who are near-sighted can only see things that are very close to their eyes. Everything else seems unclear. Many people who do a lot of work such as writing, reading and sewing become near- sighted.

However, people who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.

Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatisms (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

1.________ eye problem(problems)is(are)mentioned in the passage.

A.One B.Two C.Three D.Four

2.If you have the problem of astigmatisms, your eyes ________.

A.can only see close things B.can only see things far away

    Even if you are a good high jumper, you can jump only about seven feet off the ground. You cannot jump any higher because the earth pulls you hard. The pull of the earth is called gravity. You can easily find out the pull of the earth. If you weigh yourself, you will know how much gravity is pulling you.

Since there is gravity, water runs down hill. When you throw a ball into the air, it falls back down. Because of gravity, you do not fall off the earth as it whirls (旋转) around.

Then, can we get away from the earth and go far out into space? Now you can do it, because spaceships have been invented. Then spaceship will go so fast that it can escape the earth's gravity and carry you into space.

1.If you are a good high jumper, you can jump far higher than seven feet high.

2.You can know how much gravity is pulling you by weighing yourself.

3.Because of gravity, the water runs up hill and the balls back if you throw it into the air.

4.We can escape the earth's gravity by spaceship because it can travel very fast.

5.The Chinese meaning of "gravity" is "重力".

    The biggest secret about inventing is that anybody can do it! Perhaps this sounds crazy, but it's true. Maybe you have the wrong idea about inventing, so read on to discover the truth.

★Wrong idea No. 1: An invention has to be something completely new.

Inventing means creating something "new", but the idea could come from something that already exists(存在). The Wright Brothers, for example, got the idea for building a "flying machine" from watching birds.

★Wrong idea No. 2: Inventors are born, not made.

There are a lot of factors(因素)that make invention possible. Take Mozart for an example. He was born with a (3)talent for musical composition. But other factors were also important for his creativity. His father was a music teacher, and Mozart practiced for hours every day, from the time he was four years old. Thomas Edison said that being an inventor was "99% hard work and 1% inspiration"!

Very successful creators don't give up when they get something wrong. As one inventor said, "A failure was the right answer to the wrong question."

★Wrong idea No. 3: Inventors are always old people.

Don't believe that you can't invent something when you are young. Here are two examples of young inventors：Louis Braille went blind when he was a child. When he was fifteen, he invented a system of reading and writing for blind people that is still used in most countries today.

As a young man, George Nissen was watching some artists performing in a show. He watched how they fell into the safety net and then jumped back up again. This gave him an idea, and he invented the trampoline(蹦床).

1.How many wrong ideas about inventing are mentioned(提及)in the passage?

___________________________

2.Who got the idea for building a "flying machine" from watching birds?

___________________________

3.What does the underlined word "talent" mean in Chinese?

___________________________

4.What did Louis Braille invent?

5.Give a best title to the passage.

The Chinese version of TikTok, called Douyin(抖音), has amassed(积累) 400 million daily active users, parent company ByteDance revealed in its annual report this week. This is an impressive growth for the addictive(上瘾的) video app, which had 250 million daily active users in January last year.

The report, which describes the user behavior and trends, illustrates(表明) the cultural difference between China and the U.S., said Katherine Wu, an investor at New York-based firm Notation Capital. "Things that trend in these two countries are quite different. For example: knowledge-based content is extremely popular in China, and less so in the U.S. Also, this was wild to me: those creators that did the most dance videos in China are users born in the 60s (!!), whereas in the US, it seems that it's mostly teenagers who are creating the dances," she wrote.

ByteDance claimed (宣称) that Douyin has established itself as the largest knowledge, culture and art platform in China. (Douyin is only available in mainland China.) Indeed, 14.89 million "knowledge-based content videos" were shared on the app last year, it claimed.

    Long ago in a small, faraway village, there was a place known as the House of 1000 Mirrors. A small, happy little dog learned of this place and decided to visit. When he arrived, he bounced(跳跃) happily up the stairs to the doorway of the house. He looked through the doorway with his ears lifted high and his tail wagging as fast as it could. To his great surprise, he found himself staring at 1000 other happy little dogs with their tails wagging just as fast as his. He smiled a great smile, and was answered with 1000 great smiles just as warm and friendly. As he left the House, he thought to himself, "This is a wonderful place. I will come back and visit it often." After he came back, he told his experience to others.

Drawing might help you think

When you're sitting in class, have you ever drawn pictures in the margins of your notebooks? If so, your teacher might have told you1.(stop). Many people think of doodling（涂）as a distraction（精神涣散）from more important things. But it might be just the opposite.

One study shows that doodling may help you remember things you hear. In 2009, researchers asked two groups of people to listen to a phone message. One group2. (encourage) to doodle, but the other was not. Neither group knew that it would be asked to remember information from the message. But the group that doodled remembered 29 percent more.

Other people3.(suggest) other uses for drawing. Jesse Prinz, a professor who studies doodling, says it can help you think creatively. 4.(walk) away from a problem to draw might actually help you solve it. When you come back, you5.(have) a fresh perspective and figure out an answer more quickly.

Two years ago, an author named Sunni Brown6.(write) a book on doodling. She argues that doodling is a tool that can help people think. She admits that people see doodling as doing nothing, but she wants to change that. In fact, she runs a business that helps companies improve organization and planning doodling. Brown7.(believe) doodling is helpful because it incorporates（整合）many ways of learning. You learn in four ways: seeing, hearing, reading or writing, and through movement. The more ways you use, the8.(well) you learn. And when you doodle while you9.(listen) to a lecture, you use all four.

You might think that being good at10.(draw) is important for doodling. But if the point of doodling you think, then it doesn't matter what the picture looks like. Even if you're not an artist, doodling can help you. So next time you need help focusing, pick up a pen and doodle away!

    There are purple clothes, purple handbags, purple bicycles, purple furniture, and even purple computers! So purple is one of the most popular colors today. But in the past, purple was a very expensive and unusual color. Let's take a look at the rich_________of the color purple.

    Have you ever tried to hide your emotions（情感）from someone during a conversation? 1..

Scientists from the Ohio State University have found that people are able to tell other people's emotions according to changes in the color of their faces.

Scientists studied pictures of people's facial expressions. 2.. For example, happiness makes our faces red around the cheeks and a little blue around the chin. Disgust（厌恶）creates not only a blue-yellow color around the lips, but also a red-green color around the nose and forehead.

"We believe these color patterns are the result of small changes in blood flow triggered（触发）by the central nervous（神经）system. "Lead researcher Alex Martinez said. 3.. Does the color alone or also facial expressions help people tell other's emotions?

To figure this out, scientists added color patterns to pictures of faces that showed no facial expressions. 4. They were able to tell the emotions 75 percent of the time without any difficulty.

This is why there are some Chinese sayings that connect emotions to the color of one's face. For example, when two people are heatedly arguing over something, we say they are red in the face. When a person is very angry, we'll say he or she is blue in the face.

根据短文内容，从下列选项中选出能填入文中空白处的最佳选项,选项中有一项为多余选项。

A.Then, volunteers were asked to tell what emotions the faces were showing

B.They found that every facial expression is connected to a certain color

C.But this raises a question

D.It's not always easy, because the color on your face may tell the truth

E.It is shown that human emotions are influenced by colors on the face

A 12-year-old girl from Virginia, US, never thought that a simple message she put online could bring her big problems. She posted the words, “Killing. Meet me in the library Tuesday”, with three emojis(表情符号) of a gun, a knife and a bomb(炸弹) on Instagram, a social media(社交媒体). She was told that she broke the law because of threatening(威胁) her school.

This problem is not far away from us. Not long ago, Ni Hanxiang, a Chinese student at a university in the US, was sent back to China after expressing on social media that he would kill his teachers if he failed to pass his exams.

In China, posting threatening words online is also against the law. In 2013, Wu Hongfei, a singer, got into trouble for saying on weibo that she wanted to blow up a building.

“Threatening happens not only face to face but also through the Internet, social media and the telephone,” said Mr. Cao, a lawyer from Chongqing. “Although the law of China protects people’s right of free speech, it doesn’t include words that threaten others’ lives and national safety.”

“Some people may not mean to threaten. They may just be trying to say “I’m strong”, said Fred Pratt, a lawyer from the US.

The girl’s mother said her daughter was a good kid who had never been in trouble before. Ni Hanxiang also said he didn’t realize that what he put online was so serious.

“But not knowing the law doesn’t mean the law will treat you any differently if you break it,” says David Allen Green, a lawyer from the UK. So, do you think we’d better spend a minute or two thinking about the words or emojis we use on social media before we press “send”?

2.Ni Hanxiang was sent back to China ________.

A.because he broke the US law B.because he wasn’t honest

3.From this passage, we can infer(推断) that ________.

A.Fred Pratt thinks some people may not mean to threaten

B.the girl’s mother didn’t think her daughter was a bad child

C.Cheating in an examination at school may get you into trouble

D.Putting threatening words on QQ may bring you problems

4.This passage mainly wants to tell us that _______.

A.we shouldn’t break the US law if we study at a university in the US

B.students and singers shouldn’t post words or emojis on social media

C.students should study hard at school and not use the Internet too much

    The spring season brings warm weather, flowers and other changes for people to enjoy. For some restaurant cooks, the most exciting spring arrival is ramps.

Ramps are a wild plant in the eastern mountains of North America. They are one of the first plants that grow in the spring. Usually between April and May. They are recognized (识别) by their red stem (茎), and two long and wide green leaves. They are also famous for their strong taste, similar to onions(洋葱).

Ramps are not as well-known as other vegetables, but they have a long history in the United States. In the Appalachian Mountains, ramps have been an important food for a long time. During spring it is common for small towns in the Appalachian area to hold large ramp dinners for the community.

However, over the last 30 years, ramps popularity has grown quickly. They are now a highly-desired vegetable for many nice restaurants in cities like New York and Washington D. C.

One reason the plant is popular is that it grows in the wild. It is difficult to grow them on farms. Most restaurants get them from foragers, who collect ramps by searching forests for some small pieces of land where they grow. Ramps have a short season. Within a few weeks of full growth, the plant is done for the year. This short life is some reason for their popularity.

And that popularity could lead to their disappearance from Earth. In 1995, the local government in Quebec, Canada stopped people selling the plant to businesses in order to protect the plant against being over-dug.

The season is short, but it has not ended yet. If you are in the right place, You still have time to try a taste of ramps yourself.
