一個(gè)段落里如果沒有transitions也就很難有coherence了.我們看下面一個(gè)例子：Speaking and writing are different in many ways. Speech depends on sounds. Writing uses written symbols. Speech developed about 500 000 years ago. Written language is a recent development. It was invented only about six thousand years ago. Speech is usually informal. The word choice of writing is often relatively formal. Pronunciation and accent often tell where the speaker is from. Pronunciation and accent are ignored in writing. A standard diction and spelling system prevails in the written language of most countries. Speech relies on gesture, loudness, and rise and fall of the voice. Writing lacks gesture, loudness and the rise and fall of the voice. Careful speakers and writers are aware of the differences.

　　本段中除了第6句開頭出現(xiàn)一個(gè)起過渡作用的"it"之外，沒有使用其他的過渡詞語.這樣，文中出現(xiàn)許多重復(fù)的詞語，全段讀起來也顯得生硬而不自然。如果加上必要的過渡詞語來修飾的話，這一段就成了下面一個(gè)流暢連貫的段落：

　　Speaking and writing are different in many ways. Speech depends on sounds; writing, on the other hand, uses written symbols. Speech was developed about 500 000 years ago, but written language is a recent development, invented only about six thousand years ago. Speech is usually informal, while the word choice of writing, by contrast, is often relatively formal. Although pronunciation and accent often tell where the speaker is from, they are ignored in wiring because a standard diction and spelling system prevails in most countries. Speech relies on gesture, loudness, and the rise and fall of the voice, but writing lacks these features. Careful speakers and writers are aware of the differences.

　　4、有損連貫性的幾種情況：

　　考生在寫作中經(jīng)常出現(xiàn)下面幾種錯(cuò)誤：

　　1)不必要的改變時(shí)態(tài)，比如：

　　In the movie, Robert Redford was a spy. He goes to his office where he found everybody dead. Other spies wanted to kill him, so he takes refuge with Julie Christie. At her house, he had waited for the heat to die down, but they come after him anyway.

　　2)不必要的改變單復(fù)數(shù)，比如：

　　Everybody looks for satisfaction in his life. They want to be happy. But if he seeks only pleasure in the short run, the person will soon run out of pleasure and life will catch up to him. They need to pursue the deeper pleasure of satisfaction in work and in relationships.

　　3)不必要的改變?nèi)朔Q，比如：

　　Now more than ever, parents need to be in touch with their children’s activities because modern life has the tendency to cause cleavages in the family. You need to arrange family like it so that family members will do things together and know one another. You need to give up isolated pleasures of your own and realize that parents have a set of obligations to sponsor togetherness and therefore sponsor knowledge.

　　因此寫作中，一定要注意時(shí)態(tài)，人稱以及數(shù)的變化是否正確，要注意保持一致。
