专四应试技巧（写作篇2：句子的连贯性）
　　句子的连贯性：指句子连接贯通，衔接自然。句子不论长短都应环环紧扣，符合语法、逻辑。请注意以下要点：
　　1）平行结构：把两个获两个以上意思相近或相对的、地位相当的成分已同意与发行是泛指在一起。其中以下三条规则须加以注意。
　　a)使用相同的语法来表达具有相同功能的句子成分，可运用并列连词and, but或or等。
　　× If you want to learn a foreign language well, you’d better try to think in it and speak it as much as possible.
　　√ If you want to learn a foreign language well, you’d better try to think in it and to speak it as much as possible.
　　b)正确使用相关连词，如both…and, not … but, not only … but also等。
　　× Wang Lan is not only clever but also she is helpful.
　　√ Wang Lan is not only clever but also helpful.
　　c)一个句子或段落中的人称、时态、语态要始终保持一致。
　　× One reason I like to go to school on foot is the physical exercise I get from it.
　　√ I like to go to school on foot I regard it as a kind of physical exercise.
　　2）代词一致：句中代词应在数、性、人称等方面保持一致，或者与它所照应的名词词组在这些方面保持一致。如：
　　We each are responsible for our own jobs.
　　We are each responsible for his own jobs.
　　3）代词与先行词一致：写作时应弄清楚代词究竟指代哪个名词，否则意思不明确，造成模棱两可的感觉。如：
　　× The old woman told the little girl that she was wrong.
　　√ The old woman told the little girl,”I am wrong.”
　　√ The old woman told the little girl,”You are wrong.”
