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.

[ ]
A. there are too many human and animals on the earth
B. a lot of heat has been produced by burning of some materials

(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

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 (中風(fēng)). 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(結(jié)塊). 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.
