Can anyone tell me English grammar? Such as sentence structure and tense! Thank you for the kindness

There are eight tenses of simple present, simple past, simple future, present continuous, past continuous, present perfect, past perfect, past perfect, and past progressive perfect

Sentence structure: subject + predicate + object The subject is the sender of the action, the predicate is the action, and the object is the bearer of the action, for example, i love you i is the subject love is the predicate you is the object This is a simple sentence Compound sentences may be a little more difficult. Slowly practice the adjective clause, the object clause, the reflexive interrogative sentence, and the adverbial clause are all sentence patterns.

As a definite term for nature, it is equivalent to which was equipped....

which leads to a definite clause that modifies manner

equipped is a past participle to do a postposition definite to modify difficulties and dangers, which leads the definite clause to modify manner

1.Select anywhere else

anywhere.

somewhere.

Anywhere Other is an incorrect statement. First, other cannot be placed after the central word as a definite word; Second, anywhere is an indefinite adverb, and words that modify indefinite adverbs and pronouns should be placed later.

2.Choose on your own. The only way to achieve true fluency is to practice more on your own.

There doesn't seem to be such a thing as by your own. At least not in my Oxford Advanced English-Chinese Dictionary.

By Yourself is alone, off topic.

There is no such thing as "on yourself".

3.I choose prefer

The first verb is followed by would, and only the prefer is a verb of the three options.

4.Choose are willing to. If you're willing to work hard, you'll soon be able to get to the bottom of it.

want to is to want to do something; wouldn't be. It's not on topic.

5.Select ISN't he。

steven's off to China is short for steven is off to China. And not short for steven has off to China.

Because has is an auxiliary verb, it must be followed by a past participle of a substantive verb. There is no such past participle in the question. So hasn't't he is a false statement.

has he is even more wrong, because the anti-meaning interrogative sentence requires "the front affirms, the back negates", "the front negates, the back affirms".

6.I choose won't it。

it'll be a year is the main clause, and before we see him again is the time adverbial clause. The retortive interrogative sentence should be consistent with the subject and predicate of the main clause. Only if the main clause is "I think (believe, suppose, imagine...)."

that...When structuring, the retortive interrogative sentence is consistent with the subject and predicate of the clause.

7.I choose hasn't he。

The retortive interrogative sentence should be consistent with the subject and predicate of the main clause. Only if the main clause is "I think (believe, suppose, imagine...)."that...

When structuring, the retortive interrogative sentence is consistent with the subject and predicate of the clause.

anywhere.

on your own independently.

Rather (adverb).

are willing to.

isn't he isn't.

won't it

isn't he (consistent with clause).

Of the tens of millions who witnessed Halley's Comet in 1986, how many will live to see it again in the 21st century?

adj. enough to do sth.Enough adjCome and do something.
