Modcm inventions have speeded up people’s lives amazingly. Motor-cars cover a bundred miles in little more than an hour. Aireraft cross the world a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every ycar motor-cars are produced which go even faster each new computer boasts(吹噓)of saving preeious seconds in handling tasks.
All this saves timc, but at a prick.When we lose or gain half a day in speeding aeross the world in an airplane, our bodies tell us so. We get the uncomfoerable feeling known as jet-lag; our bodies feel tlru they have been left bebind in anot ar nine zoors Again pending too long at compulers resul’s in painti ninrts and fingers. Mobile phones also to dange according to some seientists; too much uss may thesmit h bul radiation into our brains, a we do not like to think about.
Howave, what do we do with the time we have saved?Certainly not or so it seems. We are so accustomed to constant activity that we find it difficult to sit and do nothing, or even just one thing at a time. Pcrhaps the days are long gone when we might listen quietly to a story on the radio, letting imavination take us into another world.
There was a time when some people’s lives were devotcd simply to the cultivation of the land or the eare of eattle. No multi-tasking there; their lives wenl on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so ,we must think of the hard tasks our ancestors faeed;:they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modem machinery has freed peope fre that primitive existcnee.

  Man’s first real inventions, and one of the most important inventions in history, was the wheel.All transportation and machines in the world depend on it.

  The wheel is the simplest yet but perhaps the most remarkable(值得注意的)of all inventions.Because there are no wheels in nature-no living thing was ever created with wheels.How, then, did man come to invent the wheel? Perhaps some early hunters found that they could roll the carcass(尸體)of a heavy animal through the forest on log more easily than they could carry it.However, the logs themselves weighed a lot.

  It must have taken a great prehistoric(史前的)thinker to imagine two thin slices(薄片)of log connected at their centers by a strong stick, this would roll along just as the logs did and axle(軸)came into being, and with them the first carts.

(1)

The wheel is important because ________.

[  ]

A.

it was man’s first real invention

B.

all transportation depends on it

C.

every machine depends on it

D.

both B and C

(2)

It was remarkable of man to invent the wheel because ________.

[  ]

A.

it led to many other inventions

B.

man had no use for it then

C.

there were no wheels in nature

D.

all of the above

(3)

The wheel was probably invented by ________.

[  ]

A.

a group of early hunters

B.

the man who made the first cart

C.

a great prehistoric thinker

D.

the first men on earth

(4)

This selection says that the first wheel may have been a ________.

[  ]

A.

ground piece of stone

B.

heavy log

C.

piece of mental

D.

slice of log

科目:高中英語 來源: 題型:閱讀理解

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 (邏輯) 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 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 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.

What would be the best title for the text?

A. A Way on How to Write.

B. Increase Your Brain Power through Writing.

C. Brain Power Helps Improve Your Writing.

D. How to Start Your Writing.

According to the text, writing can help you a lot in the following ways EXCEPT ______.

A. the increase of your brain power

B. the ability to remember

C. the development of your interest in study

D. the better understanding of a topic

If a writer writes something, it means that he or she ______.

A. has understood it very well

B. needs to understand it better

C. wants to remember it in his or her mind

D. is exercising his or her “explain power”

The underlined sentence “you’re half-way there” in the fifth paragraph implies

that ______.

A. you are already successful

B. you still need to work hard

C. writing can help you walk half way

D. writing is important to solve problems

What’s the main purpose of the writer writing the text?

A. To advise readers to start their writing.

B. To explain the importance of writing.

C. To persuade readers to become writers.

D. To increase readers’ brain power.

A lot of grown-ups worry that spending too much time playing video games isn’t good for a kid’s health. Now some doctors have noticed that kids who bring their hand-held game players to the hospital seem less worried about being there. These patients also seem to experience less pain when they are concentrating on a superhero adventure or a car race. At the Johns Hopkins Children’s Center in Maryland, young patients are finding hospital visits easier to deal with, thanks to a test program called the Hospital-based On-line Pediatric Environment (HOPE). Patients in HOPE have a life-threatening condition where their kidneys(腎臟)no longer filter(過濾)wastes from their blood. To get their blood cleaned, these kids must be hooked up to dialysis(透析) machines at the hospital three times a week, for at least three hours each time. HOPE allows kids to play online sports, racing, and adventure games with each other. Eventually they will be able to connect with kids in other hospitals who are suffering from the same problem. "We want to use the power of the Internet to bring together kids who feel that they are separated by their illness, and let them know that they are not alone," said Arun Mathews, the doctor who heads the program. He loves video games himself and got the idea to connect kids all over the country. Many researchers elsewhere are testing video game programs that might help young patients. For example, nine-year-old Ben Duskin of San Francisco, who was struggling with cancer helped to design a video game where players get rid of cancer cells. That’s all great news, because doctors already know that reducing pain and worry helps patients heal faster.

What’s the main idea of the passage?

A. Playing video games too much is bad for kids’health.

B. Playing video games seems to be beneficial to young patients’ recovery.

C. Doctors find that reducing pain helps patients recover faster.

D. Doctors invent a game to help kids in hospitals.

How long will it take a patient to get his blood cleaned in a week?

A. About 3 hours.   B. About 6 hours.  C. About 9 hours. D. About 21 hours.

According to Arun Mathews, the main purpose of HOPE is to _________.

A. encourage kids to play online games

B. teach kids how to design video games

C. help kids who are suffering from illness connect with each other

 D. make parents worry less about their kids playing video games too much

Which of the following plays the most important role in the HOPE project?

A. Music.  B. The Internet. C. Novels.  D. Films.

What can we learn from the passage?

A. Nine-year-old Ben Duskin, who has a cancer, is very brave and clever.

B. Many parents want their children to play video games because it’s good for their health.

C. Doctors are not sure whether reducing pain and worry can help the patients recover faster.

D. HOPE allows kids to play online games only with the kids in the same hospital.

科目:高中英語 來源:20102011學年度江西省下學期第一次段考高二英語卷 題型:閱讀理解

Many parents who welcome the idea of turning off the TV and spending more time with the family are still worried that without TV they would constantly be on call as entertainers for their children. They remember thinking up all sorts of things to do when they were kids. But their own kids seem different, less resourceful, somehow. When there’s nothing to do, these parents observe regretfully, their kids seem unable to come up with anything to do besides turning on the TV.

    One father, for example, says, “When I was a kid, we were always thinking up things to do, projects and games. We certainly never complained in an annoying way to our parents. ‘I have nothing to do’.” He compares this with his own children today: “They’re simply lazy. If someone doesn’t entertain them, they’ll happily sit there watching TV all day.”

    There is one word for this father’s disappointment: unfair. It is as if he were disappointed in them for not reading Greek though they have never studied the language. He deplores (哀嘆) his children’s lack of inventiveness, as if the ability to play were something born that his children are missing. In fact, while the tendency to play is built into the human species, the actual ability to play – to imagine, to invent, to elaborate on reality in a playful way –and the ability to gain fulfillment from it, these are skills that have to be learned and developed.

    Such disappointment, however, is not only unjust, it is also destructive. Sensing their parents’ disappointment, children come to believe that they are, indeed, lacking something, and that this makes them less worthy of admiration and respect. Giving children the opportunity to develop new resources, to enlarge their horizons and discover the pleasure of doing things on their own is, on the other hand, a way to help children develop a confident feeling about themselves as capable and interesting people.

1. According to many parents, if there’s nothing to do, the children would        .

    A. turn on the TV                           B. complain to their parents

    C. ask their parents to play with them          D. do all of the above

2. Many parents think that, instead of watching a lot of TV their children should       .

    A. sit silently studying Greek                  B. think up things to entertain themselves

    C. find chances to talk with parents            D. enjoy themselves outdoors

3.The father often blames their children for not being able to entertain themselves. This is unfair because        .

    A. the children are not really lazy, but there’s nothing for them to do

    B. they do not lack the ability to play

    C. they have to learn and develop their playing ability gradually

    D. the father have done nothing to help the children

4. When parents show constant disappointment in their children, the children will         .

    A. lose their confidence and respectability

    B. be much more disappointed

    C. refuse to learn new things

    D. discover the pleasures of doing things on their own

5.What is the author’s main idea?

    A. Today’s children are becoming less capable and independent than before.

    B. Parents should give children more help on how to be creative.

    C. Turning off the TV will help us solve a lot of family problems.

    D. It’s not just for parents and children to complain each other.
