4、有損連貫性的幾種情況：
考生在寫作中經常出現下面幾種錯誤： 1、不必要的改變時態，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、不必要的改變單複數，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、不必要的改變人稱，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，一定要注意時態，人稱以及數的變化是否正確，要注意保持一致。
