The experts summed up the notes or mistakes that Chinese people should pay attention to when writing English articles.

The goals and requirements of the following English compositions are the top priority for students in writing their texts:

1. The first paragraph is compelling:

Do your best to make the first natural paragraph fascinating, so that "words are not an astonishing Vow ". To achieve this, students are required to read a large number of extra-curricular books, including Chinese and English, with broad knowledge, flexible views, and high writing skills.

2. phrase sentence:

In English compositions, the use of phrases and sentence patterns can help to present the author's English proficiency. This requires students to systematically learn the basic knowledge. Examples:

Prefer doing> enjoy doing> like doing, we can see that different types and levels of phrase patterns can show the author's different views and levels of English.

3. compound sentence:

In English writing, the use of Compound Sentences is also essential. The primary and secondary compound sentences can be absent in Primary School English compositions. However, starting from junior high school, the primary and secondary Compound Sentences (at least 1-2) must be used in English compositions ). Only master-slave Compound Sentences can express more complex ideas. Only master-slave compound sentences can be used by readers to see the author's true English proficiency.

4. Word conversion:

The so-called associated words refer to the Adverbs Used to link up and down, the conjunction and a large number of prepositional phrases. The necessary use of intermediate Words in English compositions can make the sentence and sentence smoother, avoiding the independence of sentence separation, making the article in one go. Chinese students have mastered a large number of such words and phrases in their studies, but they seldom take the initiative to use them except but, because, and so on, making the articles quite cool and abrupt.

5. Tense:

Without doubt, tense is one of the important categories of basic English knowledge and one of the important characteristics that distinguishes it from Chinese. English compositions are used to assess students' comprehensive abilities. Therefore, you must use the tense to make your views and plots more accurate. Because Chinese do not have the concept of tense, Chinese students can easily make mistakes in English Tense or ignore the use of the situation, which will greatly compromise the written English compositions.

6:

In the English teaching philosophy of Leiman, we emphasize the importance of translation training. Both English-Chinese Translation and English-Chinese translation are essential basic abilities for English learning, or are top-level abilities. Therefore, the use of Chinese-English Translation Skills in English compositions will undoubtedly help writers to fully express their views. This kind of translation training is very lacking in most teaching materials and English classrooms. Leman English summarizes some intuitive Chinese-English Translation Skills for special effects and will be arranged for further lectures.

7. Writing layout:

It is well known that writing and formatting is the second face of a person. The writing and formatting of an essay directly affects the sentiment of the reviewers and inevitably affects the final score of the essay.

8. Extracurricular Reading and long-term training

You need to extensively read different types of books outside the classroom, especially reading some excellent articles to increase your information. At the same time, it is necessary to conduct long-term continuous training through diaries, weekly notes, correspondence, notes, notifications, text messages, and proposition writing to gradually improve the level of English writing.

To sum up, English compositions are an output of basic knowledge and an embodiment of comprehensive ability. It is a process of accumulating large amounts of information and a process of continuous cultivation.
