？？ Evenwith the best will in the world,reducing our carbon emissions is not going toprevent global warming. It has become clear that even if we take the moststrong measures to control emissions, the uncertainties in our climate modelsstill leave open the possibility of extreme warming and rises in sea level. Atthe same time,resistance by governments and special interest groups makes itquite possible that the actions suggested by climate scientists might not beimplemented soon enough.？？
？？ Fortunately,if the worst comes to the worst,scientists still have a few tricks up their sleeves. For the most part theyhave strongly resisted discussing these options for fear of inviting a sense ofcom- placency that might thwart efforts to tackle the root of the problem.Until now, that is. A growing number of researchers are taking a fresh look atlarge-scale "geo-engineering" projects that might be used tocounteract global warming. "I use the analogy of methadone," saysStephen Schneider,a cli- mate researcher at StanfordUniversity in California who was among the first to drawattention to global warming. "If you have a heroin addict, the correcttreatment is hospitalization,and a long rehab. But if they absolutelyrefuse,methadone is better than heroin. "？？？？
？？ Basically the ide？？a is to apply "sunscreen" to the wholeplanet. One astronomer has come up with a radical plan to cool Earth;launchtrillions of feather-light discs into space, where they would form. a vast cloudthat would block the sun's rays. It's controversial,but recent studies suggestthere are ways to deflect just enough of the sunlight reaching the Earth'ssurface to counteract the warming produced by the greenhouse effect. Globalclimate models show that blocking just l. 8 per cent of the incident energy inthe sun's rays would cancel out the warming effects produced by a doubling ofgreenhouse gases in the atmosphere. That could be crucial,because even the mostsevere emissions-control meas- ures being proposed would leave us with a doublingof carbon dioxide by the end of this century,and that would last for at least acentury more.？？？？？？

A.strong measures have been taken by the government to prevent global warming
B.to reduce carbon emissions is all impossible mission
C.despite the difficulty, scientists have some options to prevent global warming
D.actions suggested by scientists will never be realized
A.know what they are doing
B.feel their efforts are useless

A new experimental vaccine（疫苗） has shown promising results in the fightagainst lung cancer. In a small Texas-based study, a vaccine developed byscientists at Baylor University Medical Centre inDallas,USA, cured lungcancer in some patients and slowed the progress.of the disease in others.
Researchers have reported encouragingfindings from this small study. Forty-three patients suffer-ing from lungcancer were involved in these trials. Ten of these patients were in the earlystages andthirty-three in the advanced stages of the disease. They wereinjected with the vaccine every two weeksfor three months, and were carefullymonitored for three years. In three of the patients in the advancedstages ofcancer, the disease disappeared and in the others, it did not spread for fiveto twenty-fourmonths. However, no great difference was seen in the patients inthe early stages of the illness.
This new vaccine uses the patient's ownimmune system It is made specifically for each patient and is in-jected intothe arm or leg. It stimulates (刺激) the body's immunesystem, which then recognizes that thecancer cells are harmful, and attacks anddestroys them
The vaccine could be effective againstother forms of cancer. It offers great hope for the treatmentof cancer ingeneral, although further studies are needed before such treatment can bewidely used.
The vaccine cured all the participants in the trial.
A.Right
B.Wrong
C.Not mentioned
