五、学会活用不同的词性
　　很多考生受汉语思维的影响，经常完全依据汉语的词性对译英文，导致造出来的句子十分生硬、死板。因此，考生在平时训练时一定要注意摆脱汉语思维的束缚，学会根据具体的语境用不同的词类，这样才能写出地道生动的句子。

　　如：
　　原句：After we have observed them carefully and analyzed them critically , we may identify the conceptions that will actually contribute to the social development .
　　优化：Through carful observation and critical analysis , we may identify the conceptions that will actually contribute to the social development .
　　原句：Environmental pollution will make it impossible for human beings to survive on the earth .
　　优化：Environmental pollution will deprive human beings of the possibilities to survive on the earth .
