   The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.
Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.
A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a hose(软管) and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.
When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(潜函病). The bends can cause a diver to double up in pain. They can even kill him.
60. On the whole, this text is about _________.
A. special mixtures of gases in deep sea.
B. the problems a diver faces in deep sea.
C. air pressure under the surface of sea water.
D. a kind of illness that man suffers in the sea.
61. The text does not say so, but it makes you think that ____________.
A. deep-sea divers should be in good health.
B. divers explore the deep sea only for treasure.
C. there is a special mixture of gases under the sea.
D. diving under the water too quickly causes a kind of illness.
62. Why does a diver get the bends?
A. The air in his blood is used up.
B. His diving suit weighs too much.
C. He comes to the surface too quickly.
D. He tries to do exercise under the sea.
63. From the text we can learn that _____________.
A. man cannot stay under water for more than a few minutes.
B. the sea began to interest man in the last few years.
C. all divers will get the bends sooner or later.
D. the bends may kill a diver.

试题【   The sea has always interested man. From it he can get food, minerals, and tre】;主要考察你对题材分类等知识点的理解。[详细]
举一反三
   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 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 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.
64. 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.
65. 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.
66. The underlined word “weird” probably means __________.
A. wonderful   B. stupid    C. practical    D. strange
67. 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.

Can you train your cat to actually use your toilet? Can you not have to deal with litter boxes any more? Well for many people the answers to these questions are yes.
You may have heard that some people have managed to train their cats to use the human toilet, Well this is correct.One advantage to this is the fact that you no longer have to lug heavy bags of litter home from the supermarket, or worry about cleaning out the dirty litter everyday.
Like any other cat training program, training your cat to use the toilet takes times and patience, you just can put your cat on the toilet and hope that they can use it.
By slowly shaping your cat’s behavior over a couple of weeks, you too can end lugging heavy bags of cat litter home from the supermarket.First, start by slowly moving the litter box closer and closer to the toilet each day, so your cat gets used to being in the bathroom and being around the toilet.
Next, when you have had to litter box next to the toilet for several days, slowly raise the litter box higher and higher each day until it is at the level of the toilet.Then find an insert for the top of the toilet, like a shallow pan that can sit in the rim of the toilet and hold litter.
Once your cat gets used to using this litter pan on top of the toilet for a week or so, try removing the pan and your cat should be able to use the toilet.
Like any cat training program, it takes time and effort on the part of the cat owner to do this.Don’t get frustrated with your cat if she is not learning as fast as you would like, many cats learn at their own pace.With a little effort you too can have a toilet trained cat.

Would you eat a ready meal from the fridge rather than cook by yourself? Have you been doing Internet shopping rather than going to the stores? What can"t you be bothered to do?
A study into how lazy British people are has found more than half of the adults are so idle (懒散的) that they"d catch the lift rather than climb two flights of stairs.
Just over 2000 people were quizzed by independent researchers at Nuffield Health, Britain"s largest health center. The results were extremely surprising.
About one in six people questioned said if their remote control was broken, they would continue watching the same channel rather than get up.
More than one third of those questioned said they would not run to catch a bus. Worryingly, of the 654 respondents with children, 64% said they were often too tired to play with them.
This led the report to conclude that it"s no wonder that one in six children in the UK are classified as obese (very fat) before they start school.
Dr Sarah Dauncey, medical director of Nuffield Health, said, “People need to get fitter, not just for their own sake, but for the sake of their families, friends and evidently their pets too.”
“If we don"t start to take control of this problem, a whole generation will become too unfit to perform even the most fundamental tasks.”
And Scotland"s largest city, Glasgow, was shamed as the most idle city in the UK, with 75% questioned admitting they do not get enough exercise, followed closely by Birmingham and Southampton, both with 67%.
The results bring serious challenges for the National Health Service, where obesity-related illnesses such as heart disease and cancer have been on a steady increase for the past 40 years and are costing billions of pounds every year.
60.How many people questioned don"t play with their children?
A.1280.   B.More than 333.     C.654.    D.About 420.
61.The study leads us to believe that      .
A.the pets in the UK will be in trouble if their owners keep their way of life
B.Glasgow people feel ashamed because they don"t get enough exercise
C.British people are the laziest around the world
D.five sixths of the British children are healthy
62.How does the author convince the readers?
A.By presenting the results of a study.                 B.By providing answers to questions.
C.By interviewing some experts.                            D.By telling a story.
63.What is the passage mainly about?
A.A study of British people"s laziness.                 B.A study of British people"s lifestyles.
C.The health service in the UK.                       D.The obesity problem in the UK.

C
A gadget which makes water out of air could become the greatest househo1d invention since the microwave.
Using the same technology as a dehumidifier(除湿器),the Water Mill is able to create a ready supply of drinking water because it can always get it from an unlimited source—the air.
The company behind the machine says not only does it offer an alternative to bottled water in
developed countries, but it is a solution for the millions who face a daily water shortage.
The machine works by drawing in wet air through a filter(过滤器)and over a cooling instrument which changes it into water droplets.It can produce up to 1 2 liters a day.The Water Mill will also produce more water when storms pass over, as the amount of water which is contained in the air increases. In keeping with its eco-development, the machine uses the same amount of electricity as three lights.
Inventor Jonathan Ritchey said: “The demand for water is off the chart. So people are looking for freedom from water distribution systems that are shaky and unreliable.”
The machine, which is about 3 feet wide, is likely to cost £800 when it goes on sale here in the spring. Its maker, Canadian Firm Element Four, roughly calculates that a litre of water cost around 20p to produce.
Environmentalists state that half the world’s population will face water shortage because of climate change by 2080. One in five is said to lack access to safe drinking.
The Water Mill is not effective in areas where the amount of water contained in the air is below about 30 percent, but in Britain that won’t be much of a problem.
63.What does the underlined word “it” refer do?
A.Drinking water.       B.Invention. C.Microwave.      D.Water Mill.
64.What do we learn about the machine?
A.It works in the same way as microwaves.
B.It is very expensive for families to afford.
C.It absorbs steam and turns it into water.
D.It helps to make the water clean to drink.
65.What does the passage lead us to believe?
A.The cost of water will go up.  B.Bottled water will disappear sooner.
C.The machine is energy saving. D.The machine will be popular worldwide.
66.What’s the best title for the passage?
A.A New Way to Solve Water Problem.    B.A Machine to Make Water out of Air.
C.A Dehumidifier to Produce Water.     D.An Absolutely New Invention
