In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or whether people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers
Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments.
Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.
So why hasn’t it happened? Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them.
Telephones of Tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.
Why? The technology worked fine, but it over-looked something obvious: people’s desire for privacy. Would you want to have a video phone conversation with someone after you just step out of the shower? Probably not—it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.
1.The whole passage is mainly about .
A. predictions that have come true
B. predictions that haven’t come true
C. why predictions don’t come true easily
D. what technology will bring about
2. The author of this passage won’t believe that .
A. predictions needn’t consider people’s practical use of technology
B. the future isn’t always easy to guess
C. not all past predictions have come true
D. many of the high-tech things our parents thought we’d be using by now simply never appeared
3.The underlined word “weird” in Para. 5 probably means .
A. wonderful B. stupid
C. practical D. strange
4.What does the author think of the flying car?
A. It is too difficult to imagine.
B. It is too crazy an idea.
C. It is likely to be made.
D. It is often reported in the news.

In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
Not all past predictions have been proved wrong. A few of them have been surprisingly accurate (正确无误). Some great thinkers predicted the arrival of the credit card, the fax machine and even the internet years before they happened. But for each prediction that has come true, some others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers
Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other working environments.
Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.
So why hasn’t happened? Maybe because robots are still too expensive and clumsy(笨拙的). And probably the idea of robots cooking our dinners and washing our clothes is just too strange. At home we seem to be doing fine without them.
Telephones of tomorrow?
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.
Why? The technology worked fine, but it overlooked (忽略) something obvious: people desire for privacy. Would you want to have a video phone conversation with someone after you just stepped out of the shower?
Probably not — it could be uncomfortable! Just because technology doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy any more! But a flying car remains one of the most wonderful technology ideas to catch our imagination. Keep watching the news or perhaps the sky outside your window to see what the future will bring.
1.The passage mainly deals with______.
A. predictions that can catch our imagination
B. predictions that haven’t come true
C. new technology can benefit our life
D. predictions that have come true
2.According to the passage, which of the following statements is NOT true?
A. Technology doesn’t always mean people will want to use it.
B. Predictions don’t need to consider people’s practical use of the technology.
C. Not all the high-tech things people thought we’d be using by now are widely used.
D. High-tech things are not always convenient to people’s life.
3.Robot Helpers haven’t been used in most people’s homes because ______.
A. using the kind of robots at home is simply a waste of time and money
B. the kind of robots hasn’t been developed yet
C. people find it difficult to control the kind of robots
D. the kind of robots won’t bring people practical use
4.How does the writer find the flying car?
A. It is too difficult to imagine. B. It is too crazy an idea to realize.
C. It is likely to appear in the future. D. It has been the focus of the news.

Anyone caring about their health will be able to speak out a few of the major vitamins, and possibly take an educated guess at what they do. Vitamin C, found in oranges and other fruit and vegetables, is important for wound repair. And the much-talked-about “sunshine” vitamin D, produced by the skin in response to UV light, is essential for strong bones.
But what about vitamin P? It might well have you scratching your head. And that's not surprising: the term was first coined in the 1930s to describe a small group of compounds that provide pigment (天然色素) to plants, and were believed to have health benefits. A century later, these compounds are now better known as flavonoids (类黄酮)．
Today, scientists have identified between 4,000 and 6,000 different kinds and we now know they are responsible for many of the flavors and smells of fruit and vegetables and also that they protect them from invaders such as pests and bacteria.
They are equally important nutrients for the body, helping maintain bones and teeth, and for the production of the protein collagen (胶原), which provides structure to blood vessels, muscles and skin.
They are also said to help the body deal with some of the key drivers of illness, including oxidation (氧化), a natural process by which the body's cells age and can become damaged and defective. That means they could help to protect against chronic diseases including cancer and heart disease.
1.What do we know about vitamin P?
A.We would scratch our head if we took it.
B.It refers to the compounds also called flavonoids.
C.It was made into a coin in the 1930s.
D.People didn't think it beneficial in the past.
2.Which is NOT the function of vitamin P for humans according to the passage?
A.Helping maintain bones and teeth.
B.Assisting in producing protein collagen.
C.Accelerating the circulation of the blood.
D.Aiding the body to handle the main factors of illness.
3.Which of the following best explains “defective” underlined in the last paragraph?
A.Harmful. B.Discouraged.
C.Vague. D.Deficient.
4.How does vitamin P help slow the aging process?
A.By fighting against oxidation. B.By maintaining bones.
C.By strengthening muscles. D.By protecting against chronic diseases.
