Three Boys and a Dad

Brad closed the door slowly as Sue left home to visit her mother. Expecting a whole day to relax, he was thinking whether to read the newspaper or watch his favorite TV talk show on his first day off in months. “This will be like a walk in the park,” he’d told his wife. “I’ll look after the kids, and you can go visit your mom.”

Things started well, but just after eight o’clock, his three little “good kids”—Mike, Randy, and Alex—came down the stairs in their night clothes and shouted “breakfast, daddy.” When food had not appeared within thirty seconds, Randy began using his spoon on Alex’s head as if it were a drum. Alex started to shout loudly in time to the beat(节拍). Mike chanted “Where’s my toast, where’s my toast” in the background. Brad realized his newspaper would have to wait for a few seconds.

Life became worse after breakfast. Mike wore Randy’s underwear on his head. Randy locked himself in the bathroom, while Alex shouted again because he was going to wet his pants. Nobody could find clean socks, although they were before their very eyes. Someone named “Not Me” had spilled a whole glass of orange juice into the basket of clean clothes. Brad knew the talk show had already started.

By ten o’clock, things were out of control. Alex was wondering why the fish in the jar refused his bread and butter. Mike was trying to show off his talent by decorating the kitchen wall with his color pencils. Randy, thankfully, appeared to be reading quietly in the family room,but closer examination showed that he was eating apple jam straight from the bottle with his hands. Brad realized that the talk show was over and reading would be impossible.

At exactly 11:17, Brad called the daycare centre (日托所).“I suddenly have to go into work and my wife’s away. Can I bring the boys over in a few minutes?” The answer was obviously “yes” because Brad was smiling.

The surprising experiment I am about to describe proves that air is all around you and that it proves down upon you.Air pressure is a wonderful force.When you swim underwater, you can feel water push down your body.The air all around you does the same.However, your body is so used to it that you do not notice this.The pressure is caused by a layer of air called the atmosphere.This layer surrounds the Earth, extending to about five kilometers above the Earth's surface.

The following experiment is an easy one that you can do at home.But make sure that you are supervised, because you will need to use matches.

What you need

·A hard-boiled egg without the shell

·A bottle with a neck slightly smaller than the egg

·A piece of paper

·A match

Method

1)Check that the paper will sit firmly on the neck of the bottle.

2)Tear the paper into strips and put the strips into the bottle.

3)Light the paper by dropping a burning match into the bottle.

4)Quickly sit the egg on the neck of the bottle.

Result

Astonishingly, the egg will be sucked into the bottle.Your friends will be amazed when you show them the experiment.But be careful when you handle matches.

Why it happened

As the paper burns, it needs oxygen and uses up the oxygen (air)in the bottle.The egg acts as a seal in the neck of the bottle, so no more air can get inside.This reduces the air pressure inside the bottle.The air pressure must equalize, so more air from outside must enter the bottle.The outside air presses against the egg and then the egg is pushed into the bottle! That proves that air is all around and that it is pressing down on it.

1.Why is there the need to take care when you are doing the experiment?

A.The bottle could break.

B.You need to light the paper with a match.

C.The egg needs to be shelled.

D.The egg has to be perfectly placed on the neck of the bottle.

2.In the experiment, the burning inside the bottle can__.

A.equalize the air pressure inside and outside

B.make a seal in the neck of the bottle

C.finish up the oxygen inside the bottle

D.produce more oxygen inside the bottle

3.How did the egg put into the bottle?

A.The oxygen inside the bottle sucked the egg in.[来源:学。科。网]

B.It became salt without the shell.

C.The neck of the bottle was wide enough.

D.The outside air pressure forced it into the bottle.

4.The experiment is carried out to prove ____.

A.water pushes on your body when you swim underwater

B.the earth is surrounded by a layer of air called the atmosphere

C.the pressure of air around us has a powerful force

D.the air pressure is not equalized around us

 

阅读下列材料, 并从所给的六个选项(A、B、C、D、E、F)中选出符合各小题要求的最佳选项并在答题纸上将该选项标号涂黑。选项中有一项是多余选项。

The people below traveled abroad. Read the following stories and decide what problem each traveler experienced while traveling.

1._______ David got lost in an isolated place. To make matter worse, he had an accident and couldn’t walk freely. So he was in great need of timely help.

2.______ Paul had to buy a hamburger and ate it in the park instead of eating his mother’s delicious chicken, with which he couldn’t go through the customs(海关).

3._____ Ann was stopped at the customs because she was carrying drugs without a doctor’s prescription. How regretted she was not to have done that!

4._____ Sally offended some of the people in the town she was visiting by wearing inappropriate clothes. She should have found out about local customs and followed them.

5.______ Jack didn’t obtain a transit card when he changed planes at an airport, which made him very worried. There was no doubt that he was not allowed to get on board.

 

A  My mother was worried about me. She cooked me all my favorite dishes and put them into a box to take with me on my journey. But the customs officer inspected all the plant and animal products at the airport. Unfortunately it was illegal for me to bring into the country the kind of food my mother had given me and so it all had to be thrown away.

B  It was very hot so I put on some shorts and a T-shirt to go sightseeing. I hadn’t gone very far when I found everyone was looking at me, and they didn’t seem friendly to me. One woman even spat on me as I walked past. I decided to get off the crowded streets and so I turned down a small, quiet street.

C  During the four-day walking tour, I was amazed by mountain scenery and the ancient ruins we passed on our hike. On the last day, we arrived at the ruins of Machu Picchu in time to see the sunrise over the Andes. I spent the day visiting the ruins of that ancient Inca city before catching the train back to the capital city of the country.

D  When I got off the plane at the first airport, I saw someone handing out cards to some of the passengers, but I didn’t know what they were for, so I didn’t take one. When I tried to board the second plane they asked for my transit card, which I didn’t have. I was worried they were going to send me back to London.

E  I had been walking for about an hour when suddenly I slipped and fell down a riverbank. I hurt my ankle and couldn’t stand up. I didn’t know how I could get back to the village. I hadn’t told anyone where I was going, so no one would know where to look for me when they realized I was missing.

F  When I arrived at my destination, a customs officer at the airport looked in my bag and found the pills in a small box. He wanted to know what the pills were for and why they weren’t in their proper bottle with my name and the doctor’s name on it. I explained that the bottle had been too big and heavy. Then he wanted to know if I had a letter from my doctor explaining about the pills.
