after的词性可以是副词、介词、连词和形容词；在GMAT中的用法大概分一下几种： （1）after+名词词组：一般介宾结构，不多说 （2）after+逻辑主语+过去分词：e.g.: after an assembly-line technique introduced by Ransom Olds （3）after+doing：此时需注意doing的逻辑主语，绝大对数正确情况是单一主语的句子的主语，表示某动作之后，体现动过的先后e.g.: *The results of the company's cost-cutting measures are evident in its profits, which have increased 5 percent during the first 3 months of this year after falling over the last two years.*After suffering $2 billion in losses and 25,000 layoffs, the nation's semiconductor industry, which makes chips that run everything from computers and spy satellites to dishwashers, appears to have made a long-awaited recovery. （4）after+句子：表示某动作发生时点之后 e.g.: *Less successful after she emigrated to New York than she had been in her native Germany, photographer Lotte Jacobi nevertheless earned a small group of discerning admires, and her photographs were eventually exhibited in prestigious galleries across the United States. *Almost a decade after New York State passed laws to protect patients by reducing the grueling hours worked by medical residents, an investigation of twelve hospitals by state medical officials has found that all twelve consistently break the laws, that many residents work longer than 24 hours straight, and that more than half the surgical residents work more than 95 hours a week. *Initiated on Columbus Day 1992, five centuries after Europeans arrived in the New World, Project SETI pledged a $100 million investment in the search for extraterrestrial intelligence.
3·"In GMAT sentences, do not use the Present Progressive to indicate future actions. This usage is considered too colloquial. Instead, use the Simple Future." 在GMAT考试中，不要用现在进行时态表示将来，因为这样显得太通俗了；反而，应该用一般将来时。
