Help me solve the English problem, thank you all for helping to solve the English problem.

The reason for adding ing after present is that the latter sentence is an independent nominative structure, the subject of the first half of the sentence is tom, and the subject of the second half of the sentence is each movement, if you don't add ing, then each should be preceded by and and

Teaching can be followed by ing or not ing, mainly depending on the specific situation, if it is a statement of one thing, you need to add ing, if it is an imperative sentence, you don't need to add.

1 representing becomes a present participle, which plays the role of a definite clause in the sentence, which is equivalent to a definite clause and modifies the noun movement

That represent a word in English2 teaching sentence, your sentence is not complete, so you can't tell if it's a gerund or a present participle.

If it is a gerund, it may be used as a subject-object table.

If it is a participle, it may be made as a definite or adverbial, which needs to be analyzed on a case-by-case basis.

FYI.

Non-predicate. each movement of the hands is another subject of this sentence, so represent should be added to ing, processed as a non-predicate!

The first sentence: In the first sentence, the first sentence already has a predicate verb, so it cannot be treated as a predicate verb here. The latter sentence should be a non-predicate verb, representing a word in english The whole gerund phrase is used as a postposition of the predicate each movement of the hands

In the second sentence, the gerund-led sentence is the subject

each movement of the hands representing a word in english a sort of gestural code its complementary explanatory role.

The latter sentence should also have context.

2Which of the following is wrong?

4, this is the second time you have made.

Fill it out yourself, you'll be able to.

Is it good to check the Oxford Dictionary? Back to explain quite clearly.

a because. b while omitted i am

d Endure. A with a compound structure, the object complements the pragmatic non-predicate verb.

Determinative clauses, relative pronouns can only be preceded by which can be prepositioned.

2.b Omitted sentence, omitted i was

3.d Endure.

4.a,, with compound structure, with non-predicate verbs, its practical past participle is best. The best option in this question is A
