Passage One
Lane waited on the bench nearest the bridge, as he had been instructed. The wind blew straight across the river, sharp as a razor, and he had to pull his overcoat closer about him.
He went over his instructions in his mind. The agent would appear at four o’ clock. He would chat to Lane for a while, after which he would get up, leaving his newspaper behind. The plan would be fastened inside.
A distant clock began to strike the hour. As if from nowhere, a man appeared and sat down be side Lane, placing his newspaper on the seat between them. He was thin and middle-aged, and seemed in need of a good meat. He bored no resemblance to Lane’ s idea of a successful spy. His conversation, confined to trivial observations about the weather, was painfully uninteresting.
A few minutes later he got up and continued on his way. Large picked up the paper which laid on the bench, as if he wanted to look at the news. He was excited to
A. give Lane some important papers
B. tell him some pieces of advice

A Sunshade for the Planet
Even with the best will in the world, reducing our carbon emissions is not going to prevent global warming. It has become clear that even if we take the most strong measures to control emissions, the uncertainties in our climate models still leave open the possibility of extreme warming and rises in sea level. At the same time, resistance by governments and special interest groups makes it quite possible that the actions suggested by climate scientists might not be implemented soon enough.
Fortunately, if the worst comes to the worst, scientists still have a few tricks up their sleeves. For the most part they have strongly resisted discussing these options for fear of inviting a sense of complacency 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 at large-scale "geoengineering" projects that mig

[单项选择]At the first sight the planet Mars does not appear very welcome to any kind of life. It has very little oxygen and water, the temperature at night is below 50℃ and winds of 100 miles per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it some time in the past, and it is believed that there is enough ice at the poles to cover the planet with water if it melts. Although there is no life on the Mars now, some scientists think that there may have been some form of life long time ago. At that time, the planet had active volcanoes; the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists.
Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun"s heat in the planet"s atmosphere. With warmth, water and carbon dioxide(二氧化碳), simple plants could begin to grow. These plants could slowly make the Mars more suitable for living. It is estimated that the whole process might take between 100,000 and 200,000 years. In the meantime, people could begin to live on the planet in special closed environments. They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.People may be able to live on the Mars ______.
A. within the next 200,000 years
B. only 200,000 years from now
C. only 150,000 years from now
D. as soon as the planet becomes cool enough
