English is a very simple question .

Use that is the antecedent is a person or thing, whose is the object in the sentence, who is the subject, what is the antecedent is a thing, when is an adverb of time, which "which one (class) (one)".

When doing these clauses, it's not too late to see what the antecedent is before choosing the introductory word.

Remove e only when it ends with an unpronounced e, such as write writing and see in ee combined with the long sound i: .Wood is wood, firewood is uncountable, woods means forest.

mustn't is the meaning of must not, must not be, and needn't is the meaning of not needed, and when it appears in a multiple-choice question, it is chosen according to the meaning. For example: must i clean the desk?

no,you fill in needn here't

helping others is a habit, _you can learn even at an early age.

1.Answer: D

2.Translation: Helping others is a habit, a habit that you can learn even at a young age.

3.Explanation:

1) There is no conjunction before and after the comma in this sentence, such as and so but, which means that the latter is a non-restrictive definite clause or homonym.

This directly excludes ac, since they can neither lead non-restrictive definite clauses, nor do they be cognates of a habit.

2) That cannot be used to guide non-restrictive definite clauses, excluding b.

3) So the correct answer is d, that is, use one (= a habit) as the homonym of the previous sentence a habit, and then use the definite clause you can learn even at an early age to modify one.

Because the relative pronoun that replaces the antecedent one and is the object of learn in the definite clause, the relative pronoun of the definite clause can be omitted.

Another example: meeting my uncle after all these years is an unforgettable moment, one i'll cherish forever.

Seeing my uncle again after all these years was such an unforgettable moment, a moment that I will cherish forever.

4) If you directly use a non-restrictive definite clause, you can also use which
