　　Recently studies have shown that the earth is getting warmer. The scientists who carried out the studies say a large amount of CO2 in the atmosphere is the reason for the warming. CO2 is the gas which human and animals give off when They breathe. It is also produced when coal, oil and other things are burnt. Scientists have warned that this kind of burning is adding too much CO2 to the atmosphere. They believe the gas acts like a green house--the grass-topped building used to grow plants in cold weather. They say the gas is like the grass roof of a green house, which lets in sunlight, but prevents heat from running away. As a result, they say the earth becomes warmer.

　　One of these scientists, Dr. Hansen, says the weather will become so hot that some rivers will dry up. On the other hand, satellite pictures show us there is less ice in the Antarctic during the summer time than in earlier years. The heat would turn all the ice at both ends of the earth into water, making the oceans rise five to seven meters higher than they are now.

(1)The weather is getting warmer because ________.

[　　]

A. there are too many human and animals on the earth

B. a lot of heat has been produced by burning of some materials

C. the sun has given more heat in recent years

D. there is a large amount of CO2 in the atmosphere

(2)Farmers in cold weather build some green houses to ________.

[　　]

A. keep warm in winter

B. get some more sunlight

C. get some heat to plant some vegetables

D. prevent some vegetables from shining

(3)Too much CO2 makes the earth warmer than before because ________.

[　　]

A. it can give heat to the earth

B. it can prevent heat from running away

C. it can absorb heat form the sun

D. it cam pollute the atmosphere

(4)According to the view of Dr. Hansen, some day in the future ________.

[　　]

A. all rivers on the earth will dry up

B. the water level on land will rise five to seven meters higher

C. all ice in the Antarctic will turn into water

D. all ice on the earth will turn into water

(5)What do you think the best way to prevent the earth from getting warmer?

[　　]

A. Many animals should be get rid of.

B. Many kinds of materials should be used again.

C. The growing increase of population should be controlled.

D. Something should be done to prevent air pollution.

　　Life is never easy for the disabled．To improve understanding and raise support for people with disabilities, the United Nations made December 3 the International Day of Disabled Persons in 1992．

　　One way that life for the disabled can be improved is through new technology．

　　A recent development is an“electronic eye”that can be fitted to a pair of glasses to help the blind cross roads more safely．Last Monday, Japanese researches said the new device(装置)uses a camera and computer to sense the location of a crossing point, its width and the color of traffic lights．The camera would be at eye level, and be connected to a tiny computer．It would relay information using a voice speech system．It would give commands and information through a small speaker placed near the ear．The scientists are now working on the best way to put the device into a pair of glasses that a blind person can wear．

　　In another development, new technology is opening up the world of computers for the disabled．Thanks to a hands-free device invented in Canada, using a computer will soon be a lot easier for disabled people．The“Nouse”, short for“nose as mouse”, uses movements at the tip pf the user's nose to direct the cursor(光标)on the screen．Once the computer is turned on, an ordinary Web cam(computer camera)takes a close up photo of the tip of nose．It then mirrors the nose's movements on screen to move the cursor, just as a hand would normally move a mouse．

　　“The Nouse is also programmed to let users give orders by blinking(眨眼)．”For example, the right mouse click would require the user to blind twice and the left mouse click would require the user to blink three times, explained a researcher．

　　“Devices such as the Nouse are wonderful because they give disabled people greater independence,”said Penn-Symons, chief executive(首席执行官)of British charity(慈善团体)Disabled Living Foundation．

(1)

Through an“electronic eye”, a blind man could ________ how far to go forward．

[　　]

A．

see

B．

hear

C．

feel

D．

guess

(2)

If a disabled person wants to make two right mouse clicks and three left mouse clicks, how many times should he blink, according to the example of using the Nouse in the fifth paragraph?

[　　]

A．

Five times．

B．

Ten times．

C．

Fifteen times．

D．

Thirteen times．

(3)

How many main ways to help the disabled person does this passage refer to?

[　　]

A．

One．

B．

Two．

C．

Three．

D．

Four．

　　Even more extraordinary was that the Hatches had their farmland distributed．It was the Hatches’ wish that their legacy-a legacy of kindness as much as one of dollars and cents-should enrich the whole community and last for generations to come．

      An aspirin a day keeps the doctor away. Aspirin has long been praised as a wonder drug and has been in your family since you can remember. Not only does it cure pain, it also lowers the risk of heart attack and stroke (中风). But taking the pills daily may not work for everyone.

      Although taking an occasional aspirin or two is safe for most adults to use for headaches,body aches or fever, daily use of aspirin can have serious side effects. Up to 60 per cent of us,both healthy people and those being treated for all types of heart disease, may have some level of resistance to aspirin' s benefits.

      Aspirin keeps platelets(血小板) from sticking, lowering the risk of clotting(结块). People who are aspirin - resistant still get pain relief but not the full blood - thinning effects.

      How do you know whether you' re resistant? New blood tests can help your doctor decide whether to give you a different medicine, especially if you' re at risk or are being treated for heart disease. The tests aren' t yet widely available, but it doesn' t hurt to ask.

      People taking aspirin daily should limit the amount of alcohol they drink because of its additional blood - thinning effects and potential to upset your stomach. Thus you should not have more than one drink if you' re a woman or two dr/nks a day if you' re a man. Does daily aspirin treatment differ between men and women? Recent studies have focused on the effects of aspirin in women, finding that its effects differ between the sexes, and for women, between age groups.

     All in all, aspirin is still an effective, affordable and simple option for many people at risk of heart attack and stroke. Though it is readily available, always check with your doctor before starting daily aspirin treatment.

     B. If you are resistant to aspirin, you won' t feel pain.

     C. People taking aspirin won't suffer from heart attacks.

     D. 60 per cent of people couldn' t benefit from Aspirin.

68. What do we know about the blood tests mentioned in the fourth paragraph?   

     A. The new examination doesn' t hurt at all.

     B. The tests only help aspirin - resistant people.

     C. Doctors do the tests to test new medicines.
