The composition must be fluent in language, appropriate in words, reasonable in structure, appropriate in style and convincing.
If the number of words is not enough, some points may be deducted first. Now that you have passed the exam, it's no use worrying. If the other parts are particularly well written, you may get half a point.
Look at the scoring criteria:
19-20 score is complete,
Clear organization, rigorous article structure, correct grammar, fluent and appropriate language, changeable sentence words, and basically no language errors. 15- 18 points
The content is to the point, complete and clear, the structure of the article is rigorous, the language is fluent and appropriate, and there are a few grammatical spelling mistakes.
Wrong. 1 1- 14 is basically relevant, complete and clear, the article structure is basically rigorous, the language is basically fluent and decent, a few serious mistakes are made, and some words are inappropriate. 7- 10 point
3-6 points are basically related, complete and unclear, with obvious traces of mother tongue, more language errors and improper use of multiple words. The content is off topic, incomplete, confused, incomplete sentences, only a few sentences can be understood, and vocabulary spelling is serious.
