First of all, the topic should be clear. In the first paragraph, you usually use 1, two sentences related to the topic, and then you need to explain what you define. At the end of the first paragraph, you must explain what you want to write in the second, third and fourth paragraphs respectively.
Paragraphs 2, 3 and 4 are detailed analysis, but you should echo each other at the beginning and end of each paragraph, connecting the preceding with the following. Finally make your point clear. You will never get an answer like IELTS!
Note: 1) Before writing a composition, be sure to determine what format the teacher wants you to write the paper in. Most teachers in Britain like to write papers of 2500-3000 words in Harvard format. Remember not to copy more than 20%. You can rewrite it according to the content of the book and then mark the source. 3)ref should use at least 12-20 books.
As long as these are done, English is passable, and the basic score is 60. If you can elaborate better, it will be higher!
