Written comment to Miss Yoon student's essay( pair/group work)

The essay that my course mate and I marked is a an essay with a title 'A scary experience'. We gave this essay 7 out 20. We concluded that this student gave a clear statement for his/her essay. However, the essay has too many mechanical errors. Although the paragraphs in this essay are well arranged and we had a clear image about what the student wants to point out. But, there are too many spelling and grammatical errors. We can see that the student is using the Google Translate and translate the Chinese directly to English. That's why the sentences construction is not that complete.
