四六级考试作文写作考前指导
四级和六级考试写作虽然曾经采用相同的命题，但是评分却有差别。在写作测试和教学中，考生和教师都应该敏锐地把握这些差异。具体地讲，语汇、语型、句法和章法结构多个方面在深度和准确程度上有差异。
实际上不同的考试使用相同或者相似的命题，在国外测试中屡见不鲜。托福和雅思，GMAT 和GRE命题很多时候是相同的。可是考试的评分重点有很大的不同。
写四级作文，考生应该注意不要超过四级考试的词汇范围。句法结构要有适当的变化，但是不要使用过于复杂的从句。否则，错误的复杂句子远远不如正确的简单的句子。
我们用一道具体的题目分析四级和六级的差别。

Harmfulness of Fake Commodities
范文一
Each individual encounters such troubles as sickness and discomfort situations in his or her development. Similarly, each society is inevitably harmfully impacted by immoral or even illegal economic activities in the process of its evolvement. The most notorious and harmful among these despicable actives are fake commodities.
Fake commodities, like a virus that intrudes and cripples an organism, exert alarmingly detrimental influences on each individual consumer, the community, and the social mores as well.
They directly hurt the consumers by providing products that are priced highly but inferior in quality. Sometimes such products as faked medicine or foods can threaten consumers’ life, needless to mention consumers’ economic loss. The more fake commodities a society has, the more exacerbated the moral and ethic in that society.
What the society must immediately address is to minimize the quantity of any fake commodities and eradicate any opportunity to manufacture them. 146 words 注意现在的作文要求字数增加到了200字左右。
