Here’s an amazing way to get a hard-boiled egg into a bottle, even though the mouth of the boiled is smaller than the egg! What’s more, you don’t even need to touch the egg to get it to go in!

For this experiment you will need:

·a hard-boiled egg

·a glass bottle with a mouth just slightly smaller than the egg (a fruit-drink bottle works well)

·a 8-cm by 8-cm(3-inch by 3-inch)piece of newspaper

·a match

Remove the shell from the egg. Set the egg on the mouth of the bottle to see that the egg does not fit through the mouth.

Light the paper. Remove the egg from the mouth of the bottle and drop the burning paper into the bottle. Before the fire goes out, set the egg back onto the mouth of the bottle. Within a few seconds the egg will squeeze(挤) through the mouth and into the bottle.

As it entered the bottle, the egg may have broken into pieces. This happens when the diameter(直径) of the egg is more than about 0.5 cm(about 3/16 inch) larger than the diameter of the bottle’s opening.

Why does the egg slide into the bottle, even though no one is pushing it? Because the pressure of the air is pushing it. Before the burning paper is put into the bottle, the pressure of the air inside is the same as outside. The burning paper, however, heats the air inside. This causes the air inside to expand. When the egg is placed on top of the bottle, it seals(封住) the bottle. When the fire goes out, the air inside cools. As it cools, the air contracts(紧缩), and the pressure of the air inside becomes less than the pressure outside. Then, the higher outside pressure pushes the egg into the bottle!

The best title of this passage can be .

A. An interesting story B. The pressure of the air

C. Egg in a bottle D. Egg, bottle and match

What don’t you need in this experiment?

A. Eggs. B. Water. C. Bottles. D. Paper.

Why will the egg break into pieces while entering the bottle?

A. Because of the burning paper.

B. Because the diameter of the egg is too larger than that of the bottles opening.

C. Because it is cool inside the bottle.

D. Because the pressure of the air inside is larger.

What is the most important to get the egg into a bottle?

A. A match. B. A fruit-drink bottle. C. The pressure of the air. D. The burning paper.

Everyone has good days and bad days.

Sometimes, you feel as if you’re on top of the world. But occasionally you feel horrible, and you lose things and you cannot focus on your schoolwork.

For more than 20 years, scientists have suggested that high self-esteem (自尊) is the key to success. Now, new research shows that focusing just on building self-esteem may not be helpful. In some cases, having high self-esteem can bring bad results if it makes you less likeable or more upset when you fail at something.

“Forget about self-esteem,” says Jennifer Crocker, a psychologist (心理学家) at the University of Michigan, US. “It’s not the important thing.”

Feeling good

Crocker’s advice may sound a bit strange because it is good to feel good about yourself.

Studies show that people with high self-esteem are less likely to be depressed, anxious, shy, or lonely than those with low self-esteem.

But, after reviewing about 18,000 studies on self-esteem, Roy Baumeister, a psychologist at Florida State University, has found that building up your self-esteem will not necessarily make you a better person.

He believes that violent and wicked people often have the highest self-esteem of all. He also said: “There’s no evidence that kids with high self-esteem do better in school.”

Problems

All types of people have problems. People with high self-esteem can have big egos (自我) that can make them less likeable to their peers(同龄人), said Kathleen Vohs, a psychology professor at Columbia University.

People with high self-esteem tend to think more of themselves, Vohs says. People with low self-esteem are more likely to rely on their friends when they need help.

What to do

Researchers say it is best to listen to and support other people. Find positive ways to contribute to society. If you fail at something try to learn from the experience. “The best therapy (药方) is to recognize your faults,” Vohs says. “It’s OK to say, ‘I’m not so good at that,’ and then move on.”

The new research comes to the conclusion that high self-esteem ________.

A. is not important at all B. has taken on a different meaning

C. may not be the key to success D. does not help you do better at school

One of the conclusions of the new research is that ________.

A. feeling good about oneself doesn’t mean you lead a happier life

B. people with high esteem usually do not seek other’s help

C. people with high esteem tend to be proud

D. people with low esteem are often more popular

The underlined part “a better person” in the passage probably means a person who is ________.

A. helpful and supportive B. gentle and modest

C. likable and successful D. friendly and kind

From the text, we can infer the best therapy mentioned in the last paragraph is mainly for people ________.

A. with high self-esteem B. with low self-esteem

C. of all kinds D. who are focusing on building self-esteem

Utopia is a perfect place. It is a place without war, hunger, poverty, or crime. It is a place where the people work together and share. There is no money in Utopia because the people do not need money. They do not have personal possessions because everything belongs to everyone. All of the people are equal in Utopia, and the laws are all fair.

　 Utopia is not a new place. Plato, the ancient Greek philosopher, described a perfect society in his famous dialogue The Republic. In Plato’s Republic, philosophers were the kings, and every person had a place in the society. In 1516, Sir Thomas More wrote about an island in the Pacific Ocean where everything was perfect. He named the island

“Utopia”. In 1602, Tommaso Campanella wrote. The City in the Sun about a perfect community on the island of Ceylon (now Sri Lanka ) ; and in 1872, Samuel Butler wrote a novel about a perfect country which he named “Erewhon”. “Utopia” is a Greek word that means “not a place”, and “Brewton” is the English word “nowhere” spelled backwards.

　 Utopia is a perfect place, but it is not a real place. Most ‘real’ Utopias last only a short time. This is because everyone wants to live in it, but no one knows how to make it work. As a result, when we say something is ‘Utopia’ today, we mean that it is a good idea, but it is not realistic.

1.Which of the following would be the best t title for this passage?

A. Utopia　　　　　　　　　 B. A Good Idea　

C. A Perfect Place　　　　　　 D. The Utopian Community

2.The reason why there are no personal possessions in Utopia is that ______.

A.Plato　

B.Utopian people　

C.Tommaso, Samuel Butler and Sir Thomas More

D. A and B

4.All these Utopian communities that are mentioned in this passage were established in _____.

A. American　 .B. Indiana　 C America and India　 D.Greek

5.According to the passage, most ‘real’ Utopias last only a short time because _______.

A.no one wants to be a leader

B.no one knows how to make a perfect society

C.it is difficult to collect money

D.everyone wants to live in Utopia
