每年都有很多考生问老师，怎么提高写作？除了阅读，考研英语中占分值最大的就是写作。对于各位考研学子，大家无论学习阅读还是写作，首先要弄清楚一个问题，什么叫做好句子？
好句子绝不仅仅是把主谓宾或者主系表堆砌在一起。好句子具有一些特点。如果同学们能够把握这些特点，那么相信大家一定能够提升作文句式的表达。下面英语老师跟大家分享一下好句子的特点。
特点一：整体性
句子的整体性：即能表达单独的、完整的思想。
Eg. Born in a small town in South China in the early 50s, he grew up to be a famous musician.
【分析】这个句子表达了两层思想：1. Born in a small town出生在一个小镇 2. grew up to be a musician.长大成为了音乐家。这个句子应该分成两句来写。除此之外，还需要增加一些信息来连接两层思想。
【提升】He was born in a small town in South China in the early 50s. In his childhood he liked to sing. Later he entered a music conservatory. In the 70s, he grew up to be an accomplished musician.
特点二：连贯性
句子的连贯性：即能清晰地连接句子的各个部分，没有虚假的平行结构，没有指代不请的代词，没有不清晰的句内关系。
Eg. Upon entering the classroom, the students stood up and said, "good morning!"
【分析】这个句子从语法来讲是正确的，但是句内关系不清楚，到底谁进入了教室？
【提升】When the teacher entered the classroom, the students stood up and said, "good morning!"
Eg. Elizabeth and I enjoy walking, to ski, travel and teaching university students.
【分析】这个句子的连贯性较差，可以利用平行结构来体现连贯性。
【提升】Elizabeth and I enjoy walking, skiing, traveling and teaching university students.
特点三：准确性
句子的准确性指句子内部没有不准确的，不必要的词。
Eg. He returned in the early part of the month of August.
【分析】这个句子感觉有故意写长之嫌，需要精简。
【提升】He returned in early August.
特点四：重点突出
好的句子应该重点突出，词的选择，词的重复都有助于句子的重点突出。
Eg. When the bank robbers entered the bank they yelled, "don't move!"
【分析】这个句子比较平淡，可以修改一下动词。
【提升】When the bank robbers rushed into the bank they yelled, "don't move!"
特点五：语法正确，句式多变
句式多变指句子长短结合。如果全篇都是复杂的长难句，文章读起来会晦涩难懂，并且有挑衅阅卷人之嫌。反之，全篇都是短句，感觉有侮辱阅卷人之感。
Eg. Daisy, who was the first-year student of college, would go to a par near her school every day in morning, she would bring a small recorder with her, in park she would find quiet corner and listen to a tape of English stories.
【分析】这个句子不仅仅存在语法问题，另外还有完整性，准确性问题。
【提升】Daisy, a first-year college student, enjoys studying in the park near her school. Each morning she brings a small recorder, finds a quiet corner in the park, and listens to a tape of English stories.
如果同学们在写句子的时候，注意以上五点，相信大家一定能够写出正确，完整，准确的英文句子。
