Recently, a scientist did some experiments．He left a group of 4-year-olds in a room with a bell and a candy．If they rang the bell, he would come back and they could eat the candy．If, however, they didn't ring the bell and waited for him to come back on his own, they could then have two candies.
In videos of the experiment, he can see the children kicking, hiding their eyes--trying to exercise self-control so they can wait and get two candies．The results are different．Some broke down and rang the bell within a minute．Others lasted 15 minutes.
The children who waited longer went on to get higher SAT scores．They got into better colleges and had better adult success．The children who rang the bell quickest were more likely to have received worse teacher and parental evaluations （评价） 10 years later and were more likely to have drug problems at age 32.
The experiments are worth noting because people spend a lot of time thinking about how to improve education, how to become rich．But when the result is not good, they will come back to ask "how do we get people to get the sort of self-control that leads to success?" This is to enter the world of human nature.
So these experiments along with everyday experience, tell us that self-control is most important．Young people who can sit through sometimes boring classes to get a degree can work hard in order to learn a language well．They can avoid drugs and alcohol．For people without self-control skills, however, school is a series of failed ordeals（煎熬）．No wonder they drop out and their later life is a group of foolish ideas, such as drug use, stealing and so on.

A．test children's self control and later success

B．test children's intelligence of ringing the bell

C．find good ways of training children to learn

We can learn from the experiment that

A．all children tried to ring the bell for more candies

B．some children didn't get any candy in the end

C．the children have different self- control

Do other countries’ students also have so much homework? What do they usually do in their free time? You may feel curious about them.
On April 8, a report came out on the lives of high school students in China, Japan, South Korea and the US. It surveyed around 6,200 students from the four countries last year. You will find the answers to many of your questions in this report.
Who studies hardest?
Chinese students spend the most time studying. Nearly half of Chinese students spend more than two hours on their homework every day. That’s much more than students of the US (26.4%), Japan (8.2%) and South Korea (5.2%).

Japanese students fall asleep in class most often. About 45% of them said they sometimes doze offin class. In South Korea, it’s 32%; in the US, 21%; and 5% in China.

Once in a village, the villagers built a new church building and people came from far and wide to see it. They admired its beauty! They said it was the most beautiful building in the world. Up on the roof, a little nail（钉子）heard the people praising everything about the lovely structure – except the nail! No one even knew he was there, and he became very angry and sad.
“If I am not important, nobody will miss me if I quit!” So the nail then released (松开) its hold, got down from the roof, and fell into the mud.
That night it rained and rained. Soon, the board that had no nail was blown away, and the roof began to leak (漏水). The water flowed down along the walls and over the beautiful pictures on the walls. The plaster (石膏) began to fall, the floor was ruined, and the Bible was also ruined by water. All this was because a little nail decided to quit!
But what of the nail? While holding the board, it was not known by others but it was useful. Buried in the mud now, it was useless and would soon be eaten up by rust!
What the story wants to say is that every member is important to a whole group!
You may, like the nail, feel not important at times, but just like the nail, your absence is felt. A big building might fall to pieces. You are important to a group even if you are small.
Why did the nail decide to quit?

A．Because he was not able to hold on any longer.

B．Because he was angry and sad without people’s praising him.

Can you remember a morning when you’ve woken up to the ring of your alarm clock and wished you could stay in bed? You haven’t slept well, your hair is a mess. Worse, you can’t stop yawning. Yawning is universal to humans and many animals. Cats, dogs and fish yawn just like humans do! Yawning is an involuntary(无意识的,不自觉的) action during which you open your mouth and breathe deeply. The average duration of a yawn is about 6 seconds.
The purpose and cause of yawning are still a mystery. Scientists are not sure what causes a yawn. People yawn when they are tired or bored, but they also yawn when they aren’t. There are many ideas explaining why we yawn.
One idea is that yawning is a way for the body to become more alert by taking in more oxygen. A yawn increases the heart rate, forces carbon dioxide out of the lungs and blood stream, and brings oxygen to the brain. But one study showed that volunteers given a lot of oxygen did not yawn any less than before, while those given a lot of carbon dioxide did not yawn more.
Another idea is that early humans used yawning as a form of communication. If one decided it was time to sleep, they would tell the others by yawning and they would do it in return to show they agreed.
A third explanation comes from psychology professor Gordon Gallup of University at Albany in New York. He said that as people yawn, they cool off their brains. “Brains are like computers.” he said. “They only operate efficiently and effectively when they’re cool. Many things connected to yawning, like being tired, make the brain hot, and yawning can reduce the heat.”
Scientists have sent people into space, and created terrible nuclear weapons, but there are lots of seemingly simple things, such as why we yawn, or hiccup（打嗝）, that they can’t figure out. Next time you are in class in the morning, let out a big yawn and watch to see how many of your classmates yawn in response!
What’s the purpose of the description of how bad you may feel when you’re woken up in the morning?

A．To explain why humans yawn.

B．To explain how humans start yawning.

C．To lead into the topic of yawning.

D．To complain about being woken up by the clock.

Which is not among the possible reasons for yawning mentioned in the passage?

A．A way to show that you feel hot.

B．A way to get rid of carbon dioxide.

C．A way to cool off your brain.

D．A way to communicate.

In which situation are you likely to yawn?

A．When you feel frustrated.

B．The weather is hot.

C．Someone else yawns near you.

D．When you breathe in a lot of carbon dioxide.

What can we learn from the passage?

A．The real reason why humans and most animals yawn.

B．Hiccups are an involuntary human action similar to yawns.

C．The more an action can be studied, the easier it is to research.

D．Finding out why humans yawn should be easier than sending people into space.

Every family with kids has seen its share of arguments, shouting and complaining. It turns out that all those conflicts serve an important purpose in the development of children . Saying “no” followed by a bad temper, just may be an unavoidable part of growing up. And that’s a good thing. These are the first steps toward independence. Even young children have to challenge their parents sometimes. Studies have shown the following:
·Although stressful, conflicts are beneficial for children.
·Learning to manage conflicts is necessary for a child’s development.
·Conflicts during the preschool years occur because children desire more attention than parents can or should give.
If you understand why conflicts occur, it can minimize the conflicts between you and your children. Conflict is a child’s attempt to develop a sense of self and how he or she learns to express his or her needs and ideas. Parents develop and drive this independence by putting children to the outside world both formally and informally.
Conflicts can grow out of a difference of opinion or might just be a way to blow off steam(发脾气). In rare situations, constant conflicts between parents and children can indicate a deeper emotional problem. Consult your doctor if this seems to be your situation.
It’s important to offer your child choices, which should be determined by age and developmental level. The more responsible a child is, the more choices he or she gets in reward. You can threaten your child with punishment, but often offering a choice will better improve angry situations. Consequences and rewards should have some meaning to your child.
Often a child’s adverse(敌对的)reaction when he or she hears the word “no” can be avoided by giving the child an explanation as to why you have refused his or her request.
