　　【Abstract】Writing a cohesive academic composition is one of the fundamental abilities required of colleges students. Though many English learners can convey the ideas of thinking， information， even the speech easily， they sometimes feel difficulty in meeting the criterion of academic accuracy requested by teachers. This essay deals with some writing skills， suggestions and solutions for it.

　　1. Introduction
　　Loose-jointed essay writing sometimes is ubiquitous among the second language learners’ works， which is features by long disconnected paragraphs and sentences， especially for over using subordinate clauses. It is hard to correct， due to tinkering with conjunctions would not solve the problems and the normal shorthand is inadequate， and rewriting the essay is the proper way they can do. A large number of writers take English workshops or classes at universities. They can manage the organizational abilities of the courses， however at the end of the day， they yield poor writing. I would like to analyze some errors in university students’ works， first for content and second for grammatical problems. The result is that majority of the errors is because of wrong sentence construction. The following paragraph is a good example， partially corrected：
　　Example 1：
　　Traditional buildings are very strong， they are not expensive to construct， they have many disadvantages like the roofs can not last for a long time. They leak mouses and other animals make their homes there， also they transmit disease. The single rooms are sometimes very small holding many family members， they cook in a small kitchen， usually small kids are sleeping close to the fireplace，， and the toilet may be far away.
　　Mentor’s comments for this is ‘try to write a simple English is not really helpful’ because one student has little idea as to what makes up a right sentence and once they do succeed in writing simple English， they are attempt to produce baby English. To some extent we prefer the writing is not communicative， although with reader’s collaboration. This essay copes with the types of error which highlight incoherent writing and suggest some ways to solve them.
　　2. Concept of sentence.
　　Some grammatical mistakes can be identified by teachers extremely easily， and usually remedied by writers once attention is instructed to them. Others appear to show a more fundamental misconception by writers as to what is acceptable as a cohesive sentence. It is the second area which accounts for loads of incoherent writing. My results show that some grammatical mistakes was due to inaccurate misunderstanding of what compromised a correct sentence. The main fields of mistakes are listed below：
