Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.
The first is called the "tank test". A modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构)of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is try­ing to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.
The most dangerous test happens when the new plane is going through test flights in the air. The test pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.
68. By doing the "tank test", the engineers can find out _______.
A. the amount of air in the plane
B. the strength of the plane structure
C. the pressure inside and outside the plane
D. the power of the airplane engines
69. What will happen to the plane under the "tank test"?
A. It will be broken.                    B. It will be made stronger.
C. It will be filled with water.                  D. It will be tested by pilots,
70. According to the text, why are test flights most dangerous?
A. The plane may explode in the air.           
B. The pilot may lose control of the plane.
C. The engines may be damaged.              
D. Too much air may get into the plane.
71. What might be the most suitable title for the text?
A. Two Important Tests on Airplanes
B. The Importance of Flying Safely
C. The Danger of Testing Airplanes
D. How Airplanes Are Made and Tested

Have you ever noticed what happens to an idea once you express it? Just talking about it or writing it down causes you to make it clear in your own mind.How can you use this to increase your brain power? Start writing.
By putting thoughts into words, you are telling yourself the logic (逻辑) behind what you think, feel, or only partly understand.Often, explaining a thought is the process of understanding.In other words, you increase your brain power by exercising your “explain power.”
Try this experiment.Explain how you’ll increase your brain power, even if you have no idea how right now.Just start with anything, and create an explanation.For example, start with “I’ll learn chess,” or “I’ll read an article on the mind every week.” Explain how that will help.You’ll be surprised how often this becomes a workable plan, and if you actually do this, you’ll have a better understanding of your brain twenty minutes from now.
Another benefit of writing is that it helps you remember.Many, if not most, highly productive people are always taking notes.You can try keeping it all in your head, but if you keep a journal of your ideas the next time you’re working on a big project, you’ll probably have more success.
Want to understand a topic? Write a book about it.That’s an extreme example, but if you are learning something new, write a letter to a friend about it, and you will understand it better.Want to invent something? Write an explanation of the problem, why you want to solve it, and why it is worth solving, and you’re half-way there.
Writers don’t always write because they clearly understand something beforehand.Often, they write about something because they want to understand it.You can do the same.Writing will help bring you to an understanding.Give it a try.

A.A Way on How to Write

It was a beautiful day at the beach—blue sky, gentle wind, calm sea.I knew these things because a man sitting five feet from me was shouting them into his mobile phone, like a play-by-play announcer (实况解说员).
“IT’S A BEAUTIFUL DAY,” he shouted.“THE SKY IS BLUE, AND THERE’S A GENTLE WIND, AND THE WATER IS CALM, AND…”
Behind me, a woman, her mobile phone pressed to her ear was walking back and forth.
“She DIDN’T,” she was saying.“No.She DIDN’T.She DID? Really? Are you SERIOUS? She did NOT.She DID? No she…”
And so on.This woman had two children, who were playing in the sea.I found myself watching them, because the woman surely was not.A huge squid could have caught and snatched the children, and this woman would not have noticed.Or, if she had noticed, she’d have said, “Listen.I have to go, because a huge squid just……No! She didn’t ! She DID? No! She……”
And next to me, the play-by-play man would have said: “…AND A HUGE SQUID JUST ATE TWO CHILDREN, AND I’M GETTING A LITTLE SUNBURNED, AND …”
It used to be that the major trouble at the beach was the fellow who brought a boom box (便携式录音机) and turned it up so loud that the bass notes caused seagulls to explode.But at least you knew where these fellows were; you never know which beachgoers have mobile phones.You’ll settle next to what appears to be a sleeping sunbather, or even (you hope) a corpse , and you’ll lie happily on your towel, and you’ll get all the way to the second sentence of your 467-page book before you fall asleep to the hypnotic surge of the surf (催人入梦的潮声), and …
BREEP! BREEP! The corpse sits up, feels urgently for its mobile phone, and shouts “Hello! I’m at the beach! Yes! It’s nice! Very peaceful! What? She did? No, she didn’t! She DID? No, she…”
Loud mobile-phoners never seem to get urgent calls.Just once, I’d like to hear one of them say, “Hello? Yes, this is Dr.Johnson.Oh, Dr.Smith.You’ve opened the abdominal cavity (腹腔)? Good! Now the appendix should be right under the … What? No, that’s the liver.Don’t take THAT out, ha ha! Oh, you did? My God! OK, now listen carefully…”

Scott Langteau has this message for kids: Spend less time playing video games.
It’s a message that many a mom and dad has tried to impress upon many a youngster (and some not-so-youngsters) who spends perhaps a bit too much time with game controllers in hand.
But the 40-year-old Langteau isn’t a parent.He’s experienced at video games — one who played producer on three “Medal of Honor” games and co-founded his own game development company.
Langteau has just published a children’s book called “Sofa Boy,” which tells the story of a kid who spends too much time sitting on the couch with controller held in hand and the rather terrible consequences that follow.
It’s a fairy tale plucked straight from Langteau's own experiences as a lad with a fondness for video games and his own bouts with a bit of game addiction.But first, Langteau would like to make one thing clear: “I’m not saying that you shouldn’t play video games.I think video games are great, I think they do great things for kids”.Instead, Langteau says his book is all about a little something called “moderation.(克制)”
“It’s about being well rounded,” he says.“Just like with anything else, we all need to make sure that there’s a variety in what we do.”
Video gamers can be rather bad-tempered when it comes to accepting criticism about their favorite entertainment.And understandably so.After all, most people who go around talking about the dangers of playing video games tend to be outsiders — people who don’t play video games and certainly don’t understand that they can be a valuable and healthy form of entertainment.
But Langteau and “Sofa Boy” seem to be in a unique position to deliver a message of gaming moderation that the young game-savvy(有经验的) masses might actually listen to.After all, this is a man who understands what it means to be a kid with a passion for games.His early experience has taught him a lesson.
Scott Langteau published “Sofa Boy” to

A.share his great skills on games
B.warn kids against game addiction
C.tell about his fairy tale as a kid

C.playing video games ruins the future of kids
D.playing video games is of no benefit to kids

Frank Woolworth was born in Rodman, New York., in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be farmer. He took a short business course, and went to work as a salesman in a large city.
Woolworth realized he had a natural skill for showing goods to attract people’s interest, but he soon learned something more important. One day his boss told him to sell some odds and ends (小商品) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.
Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly form the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.
By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world. He always run his business according to strict rules, of which the most important was: “ THE CUSTOMER IS ALWAYS RIGHT.” (词数268)
