批改与评分如下:
Overall, the essay is well-organized and conveys the main points effectively. However, there are some areas for improvement in terms of grammar and vocabulary usage.
Firstly, there are some grammatical errors throughout the essay. For example, in the first paragraph, "it's easily for us to understand" should be "it's easy for us to understand." In addition, the phrase "nunners could easily keep a running habit" should be revised as "runners can easily maintain a running habit."
Secondly, there are some vocabulary choices that could be improved. For instance, instead of "guard against diseases," it would be more appropriate to say "prevent diseases." Furthermore, instead of using "tiredness," the word "fatigue" would be a better choice.
In terms of content, the essay adequately supports the main idea that exercise, particularly running, is beneficial for a healthy life. However, it would be helpful to provide more specific examples or evidence to support these claims. For instance, mentioning studies that show how exercise improves immunity and sleep quality would strengthen the argument.
Based on the above analysis, I would rate this essay in the second band, 19-24 points. The essay effectively conveys the main points and meets the basic requirements of the task, but there are some errors in grammar and vocabulary that slightly affect clarity. Overall, it is a solid essay with room for improvement. |
