I 写作高分句式解读
句子是一篇文章的基石。作者的立场、理由和论述，全部都要通过句子来表达。如果句子写不清楚，文章的意思无法清楚表达。学生在作文当中需要特别注意下列这些问题。
1、必须表达统一、完整的思想内容
1) 不密切的内容不应写在同一句内。如：
As we were driving out into the country, we met a man riding a bicycle, and we passed a truck fully loaded with vegetables, and on our way back we stopped at a grocery to get some fruit.
这句话虽然只有一个主语，但其内容并非紧密关联。应该分为三句，使各句分别包含某一方面的内容而体现统一性。修改如下：
As we were driving out into the country, we met a man riding a bicycle. Later, we passed a truck fully loaded with vegetables. On our way back, we stopped at a grocery to get some fruit.
2) 不可以把一个不能独立存在的分句或短语作为一个独立句。如：I did not hear him when he entered. Because I was in a sound sleep. 有的句子从语法结构上看是完整的，但从意义上说却是不完整的。如：Shanghai is the biggest city.缺少in China这个定语。
3) 句中各成分之间的关系必须正确表示。在I am not surprised that he failed in the examination, he had not been working very hard.一句中的两个部分显然缺乏必要的联系。只要在它们之间加上连接词for就能正确显示二者之间的关系。如果错用连接词也会产生含义不清的后果。例如在The condition of the patient got worse when he was given every attention.一句中，只要把when改成though或even though，语意就会变得清楚。有时还由于错误使用句式结构而造成含义不清的情况，如并列句Studying in the libraries can help the students focus on the learning materials, and we know that libraries are usually a quiet place.应改为复合句Studying in the libraries, which we know are usually quiet, can help the students focus on the learning materials.这样才能表达统一完整的含义。
4) 在一句中不可任意改变视角。例如在Calling someone who he recognizes for help is the first idea appear in his mind.中出现了两个视角和两个谓语动词。应该改为Calling someone who he recognizes for help is the first idea appearing in his mind.
2、必须具备连贯性
句中各个部分之间的关系应合乎逻辑。以下各种情况均会影响句子的连贯性。
