27、nger from diseases.Bcan36如何做到行文流畅 高考书面表达的评分原则中明确规定“上下文的连贯性”为评分时应注意的主要内容之一。在“各档次的给分范围和要求”中，也提到了“连贯性”的问题，且在第五档(2125分)中具体指出：“有效地使用了语句间的连接成分，使全文结构紧凑。”那么如何使行文连贯呢？其实，做到行文连贯一点也不难，只需掌握以下两个要诀。 写作技能37 要诀之一 要组织一段通畅的英文，构建每一个句子时，要 服从以下三条原则: 1.The topic of each sentence mustnt be changed. 2.The subject of each se

28、ntence has to be changed. 3.The beginning of each sentence should be changed.38 有些句子的主题、主语和句子的开头可能是同一结构，但并非总是如此。如果在一段文章中，每句话的主题、主语和开头都是同一结构，便显出一种学生腔。事实上，每个句子的主题不能脱离整段的主题。每个句子的主语会因叙述的内容不同而不同。流畅的段落每一个句子的开头一般是不同的。因此，在一段英文中句子的主题不能变；句子的主语需要变；句子的开头必须变。 这就是行文连贯的要诀之一。39 要诀之二 正如许多人所认识的那样，要使作文行文连贯、条理清楚，就要适当地使

29、用连接成分，其中包括连词、副词、话语标志、用作状语的介词短语和部分独立结构。 很多连接成分具有多个方面的功能，在写英语作文时，要合理运用。同时，在写作中切忌连接词语的堆砌，不要因文害义。正如前边所提到的那样，普通的副词在句中位置十分灵活，所以，副词也是使文章行文连贯的最好工具。另外，充当状语的介词短语在文章中的连接作用也不容忽视。401.There are various (方法) that have to be learned before one can do the job properly.2.The United States (进口) sugar from Cuba.3.There
