今年六级考试改错加大了难度，很多考生反映不知道如何做综合改错。从历年考试趋势来看，改错的难度比较大，考生也很容易失分。以下介绍一下改错的应试对策：
1、 首先要快速浏览全文一遍，大概了解文章大意，切忌拿起来就改；
2、 从上下文的关系里找出连接关系和逻辑关系上错用的词；
3、 从句型、词类的固定搭配(如动词、形容词、介词等词类的搭配)及其它习惯用法上找出错误或用法不当之处；
4、 从语法的基本要求出发去发现语法错误(如名词的性、数、格，动词的时、语态、语气、数等)；
5、 在这基础上，必须充分发挥理解、推理、判断乃至猜想能力，加上以往的经验，使前后左右相互呼应；
6、 实在找不出来时，挑一个可能错了的词并进行改正。这是因为，改错了扣1分，不改还是扣1分。所以，改了总比不改好，说不定还改对了呢。

(1) Until the very latest moment of his existence man has been bound to the planet on which he originated and developed. Now he had the capability to leave that planet and move out into the universe to those worlds which he has known previously only directly. Men have explored parts of the moon put spaceships in orbit around another planet and possibly within the decade will land into another planet and explore it. Can we be too bold as to suggest that we may be able to colonize other planet within the not - too - distant future ﹖ Some have advocated such a procedure as a solution to the population problem. ship the excess people off to the moon. But we must keep in head the billions of dollars we might spend in carrying out the project. To maintain the earth"s population at its present level, we would have to blast off into space 7500 people every hour of every day of the year. Why are we spending so little money on space exploration﹖ Consider the great need for improving many aspects of the global environment, one is surely justified in his concern for the money and resources that they are poured into the space exploration efforts. But perhaps we should look at both sides of the coin before arriving hasty conclusions.

2 More people die of tuberculosis(结核病)than of any other disease caused by a single agent .This has probably been the case in quite a while. During the early stages of the industrial revolution, perhaps one in every seventh deaths in Europe"s crowded cities were caused by the disease .From now on, though western eyes missing the global picture saw the trouble going into decline .With occasional breaks forward the rates of death and infection in the Europe and America dropped steadily trough the 19th and 20th centuries. In the 1950s, the introduction of antibiotics(抗菌素)strengthened the trend in rich countries and the antibiotics were allowed to be imported to poor countries. Medical researchers declared victory and withdrew, they are wrong .In the mid-1980s the frequency of infections and deaths started to pick up again around the world .Where tuberculosis vanished, it came back in many places where it had never been away ,it grew better. The World Health Organization estimates that 1.7 billion people a third of the earth"s population suffer from tuberculosis. Even when the infection rated was falling population growth kept the number of clinical cases more or less constantly at 8 million a year .Around 3 million of those people died nearly all of them in poor countries .
