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!
1.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
2.What don't you need in this experiment?
A.Eggs. B.Water. C.Bottles. D.Paper.
3.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.
4.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.

Last night, I was waiting for a taxi. After 5 minutes, I was 36 . The driver seemed to be angry. I asked him what the 37 was. He said he had just come from the airport without a 38 , which was basically $70 in lost fare.
Over the course of the ride, the anger 39 died down. He mentioned he had read an article saying the 40 people are the ones that give, so he hoped he’d have more 41 to give in his life. I was starting to 42 being with him! We continued talking about why 43 is so beneficial both to the giver and the receiver and different ways to 44 it.
As we arrived at my destination, I 45 my fare. But I pulled out an extra $20 and said, “Since we’ve been talking about this whole time, I wanted to share that 46 with you. I’ve already paid my fare, but here’s an extra little bit. You can 47 it, since you’re already down $70 from the airport. But if you want to experience the 48 of the gift, then tell the next passenger in this taxi that their ride is a gift from another and they can 49 their gratitude(感激) in whatever way.”
The man turned toward me, tears in his eyes, and said, “Sir, I have a better 50 . You give that $20 to a 51 person around here and I’ll treat the next passenger with a 52 ride myself.
Wow. This man was 53 10 minutes ago. I got out and walked around trying to 54 someone who needed help before heading to my destination.
It was an honor meeting that driver and 55 the lesson of how everyone is capable of giving.

Hi! Have you ever suddenly felt that someone you knew was in trouble — and was he? Have you ever dreamed something that came true later? Maybe you have ESP (超感觉知觉).
ESP stands for Extrasensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.
Here's an example. A woman was ironing clothes. Suddenly she screamed, "My father is dead! I saw him sitting in the chair!" Just then, a telegram came. The woman's father died of a heart attack. He died sitting in a chair.
There are thousands of stories like this one on record. Scientists are studying them to find out what's behind these strange mental messages. Here's another example—one of hundreds of dreams that have come true.
A man dreamed he was walking along a road when a horse and carriage came by. The driver said, "There's room for one more." The man felt the driver seemed dead, so he ran away. The next day, when the man was getting on a crowded bus, the bus driver said, "There's room for one more."
Then the man saw that the driver's face was the same face he had seen in the dream. He wouldn't get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!
Some people say stories like these are coincidences. Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind.

Do you want to live with a strong sense of peacefulness, happiness, goodness, and self-respect? The collection of happiness actions broadly categorized as “honor” help you create this life of good feelings.
Here’s an example to show how honorably actions create happiness.
Say a store clerk fails to charge us for an item. If we keep silent, and profit from the clerk’s mistake, we would drive home with a sense of sneaky excitement. Later we might tell our family or friends about our good fortune. One the other hand, if we tell the clerk about the uncharged item, the clerk would be grateful and thank us for our honesty. We would leave the store with a quiet sense of honor that we might never share with another soul.
Then, what is it to do with our sense of happiness?
In the first case, where we don’t tell the clerk, a couple of things would happen. Deep down inside we would know ourselves as a type of thief. In the process, we would lose some peace of mind and self-respect. We would also demonstrate that we cannot be trusted, since we advertise our dishonor by telling our family and friends. We damage our own reputations by telling others. In contrast, bringing the error to the clerk’s attention causes different things to happen. Immediately the clerk knows us to be honorable. Upon leaving the store, we feel honorable and our self-respect is increased. Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility.
There is a beautiful positive cycle that is created by living a life of honorable actions. Honorable thoughts lead to honorable actions. Honorable actions lead us to a happier existence. And it’s easy to think and act honorably again when we’re happy. While the positive cycle can be difficult to start, once it’s started, it’s easy to continue. Keeping on doing good deeds brings us peace of mind, which is important for our happiness.
【小题1】According to the passage, the positive action in the example contributes to our__________.
A.self-respect | B.financial rewards |
C.advertising ability | D.friendly relationship |
A.lying | B.stealing | C.cheating | D.advertising |

D.reminding the clerk of the charged item |
A.We’ll be very excited |
B.We’ll feel unfortunate |
C.We’ll have a sense of honor |
D.We’ll feel sorry for the clerk |
A.How to Live Truthfully |
B.Importance of Peacefulness |
C.Ways of Gaining Self-respect |
D.Happiness through Honorable Actions |
