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(擠) through the mouth and into the bottle.

As it entered the bottle, the egg may have broken into pieces. This happens when the diameter(直徑) 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(緊縮), 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.

Abby Subark is a mother of two from Boston. “For my kids, I’m nervous. I don’t know if they’ll be able to achieve their American dream.” She may be right. More than hard work or education, the best way to get rich in America is to be born rich.

It is the case that somebody who is in the upper third of income, poor scores, in the bottom on tests when they are in eighth grade, is more likely to go to college and finish college than a poor kid with the top scores. That’s what the working persons’ children are faced with.

The Economic Policy Institute finds it would take a poor couple with 2 children 9 or 10 generations to achieve middle class status. That’s about 200 years. The typical feature of American opportunity has always been the ability to do better than your parents. But compared with similar developed countries, the United States ranks fifth out of six for so-called intergenerational mobility (變動).

If you look at the mechanisms (機制) for upward mobility that were so readily available 50 years ago, they are becoming out of reach, like plentiful factory jobs with good wages and affordable education and health care.

White families are twice as likely as blacks to be upwardly mobile. For most people in America today, where you end up depends on where you start.

If you started in the middle-income class, about 40 to 45 percent of what you are making right now is due to the fact that your parents were in the middle-income class. The rest is up to you.

But for the millions of people who find themselves below the poverty line and the millions more who are the working poor, their starting point for the American dream leaves them painfully far away from the middle class.

71. The main idea of the passage is _______.

A. How the middle class comes about in the U.S.

B. It’s hard to realize the American dream for the poor.

C. Wealth and social status depend on family background.

D. Upward mobility in America is never easy.

Which of the statements is NOT TRUE according to the passage?

A. People used to have job opportunities and welfare for upward mobility.

B. A great many poor people can hardly realize their American dream.

C. You can make all your dreams come true in America if born rich.

D. Rich kids are more likely to go to college than poor kids.

73. The underlined sentence “where you end up depends on where you start” most probably means _______.

A. Your starting point cannot determine your destination.

B. Only a high goal can ensure success.

C. One’s birth has nothing to do with his fate.

D. One’s family lays solid foundation for his future achievements.

Why is Abby Subark nervous?

A. Her kids don’t want to compare with other rich kids in achievements.

B. Her kids don’t want to achieve success at all.

C. Her kids can achieve success through hard work and education.

D. Her kids can’t reach their goal without a rich family.

What can we infer after reading the passage?

A. Poverty causes people much pain.

B. People below the poverty line can never be in the middle class.

C. Lower starting point makes it hard for people to realize their dream.

D. Poor people’s starting point is too low.
