Introduction extension sentence
1, the answer to the extended sentence is not unique. As long as the sentence trunk is explained reasonably and concretely, the result is the correct answer.
2. A sentence generally includes a subject and a predicate. The subject says "who" or "what" and the predicate says "how" or "what to do". The process of adding branches to this trunk to make the meaning of a sentence more concrete and vivid is to expand the sentence.
3. Sentence expansion commonly used skills are:
① Partially expand grammar. That is, the sentence is divided into two parts, namely, the subject part and the predicate part, which are expanded first and then expanded.
② Overall extended grammar. For example, "the red flag is up" can be held according to "where and how" what kind of "red flag" is. The bright five-star red flag rises slowly on the top of the teaching building.
