Give 50 points: English questions related to attributive clauses (note: detailed explanation)

To make it easier to understand, you can simplify the main sentence into a declarative sentence first.

Is this the factory that you visited the other day?

After reduction, we can see that the main clause is complete and the clause lacks the object component, so we can't choose B; And because visit is a transitive verb, there is no need to add a preposition after it, so C excludes the antecedent "the factory" in option A, which guides the attributive clause and acts as an object in the clause, so choose A.

(2) last Friday some foreign friends visited the factory is _ _ _ _ _?

After reduction, we can see that the main clause lacks predicates, so we choose option D. One is both the antecedent and the predicate in the main sentence, and the relative word "that" is omitted later.

That is: this factory is the one that some foreign friends visited last Friday. You can omit the object in the attributive clause.

Supplement:

As you said, there are two different antecedents: the antecedent "factory" and the antecedent "one".

Why not choose other relative words in the second sentence? First of all, because the clause lacks an object, it is necessary to use relative pronouns. Another reason is that the relative word in the attributive clause must be preceded by a modifiable antecedent. If you choose A.B.C, not only the main clause is incomplete, but also the clauses lack antecedents. So choose D.

Those wolves hide where others can't find them.

This clause lacks a subject, so you can only choose relative pronouns.

The b option "where" can only be used as an adverbial in a clause because it is a relative adverb.

C option "in which" plus preposition "in", because found is a transitive verb, directly add the object.

"Which" can of course be chosen.

The option "in that" as a conjunction indicates that due to ...

Therefore, B.C.D excludes and chooses A. That to guide the attributive clause and act as the subject in the clause.

This book will tell you that _ _ _ _ _ can be used in other occasions.

"How, what, that" in the option can guide the subject clause (noun clause).

But in this sentence, show is followed by a double object. The main clause lacks an object component and the clause lacks a subject component (the clause uses "subject clause" as the "subject component" of the clause). After analysis, among the four options of A, B, C and D, only B can "take this heavy responsibility"! ! ! Others can't do this work, because only the subject clause led by what acts as the object of the main clause, and what itself acts as the subject of the clause.

This sentence is translated into:

This book tells you that what you observe can also be used in other environments.

4. Predicative clauses are placed after conjunctions and act as predications in complex sentences, which can not only guide conjunctions.

Questions such as why, when, where, who, how and where can be guided. For example:

(1) The question is who can we find to replace her.

The question is who can we find to replace her.

The question is how he did it.

The question is how he did it.

This is what she did when she arrived in the attic this morning.

That's what she did when she went to the attic this morning.

The question is whether they can help us.

The question is whether they can help us.

In addition, the conjunction because can also guide predicative clauses. For example:

I think it's because you have done too much. I think it's because you do too much.

In the option, A. Because B. Why C. Then D. Whether.

Everyone can guide predicative clauses, but why means "result" and because means "cause", and they all have their own meanings (why ... because ...). Only that is just used as a guide word and has no meaning. The reason is that he can't operate the machine. It is obviously meaningless to choose a.b.

This sentence is an attributive clause, and there is no object in it. If you choose relative pronouns, you can see A, B and C at first sight. But if you choose a and b, what should you use as the object of from? Therefore, c. one is chosen as the object of the main clause and the antecedent of the clause. As for why there is no clause guide, it is because it can be omitted as an object in the attributive clause, that is to say, it is very different from my last Harle's "the one(that)".

6. This sentence is a non-restrictive attributive clause. The antecedent is human, so C is excluded, and the antecedent is "two sons", so A and D are excluded. I think you know why D is excluded. As for the option that "two of them" means "two sons" in the main sentence, A is excluded. B was chosen.

7. Look at the comma in the sentence. This sentence is a single sentence. If you choose a, it becomes two sentences.

Of course, if you remove the comma and add the conjunction "and", you can satisfy your wish to choose A. Hmm. How interesting

Interested in ... interested in fixed collocation.

Only by understanding this can we rule out C.

The option "in that" is excluded from the list of conjunctions because ...

As for option A, "in it" is wrong! ! If you choose A., the subject is missing the object, and the object has no modifiable antecedent. Option d actually omits the leading word "that", that is, "they are interested in anything you have"? Everything is the object of the subject preposition and the antecedent of the clause.

Summary: An attributive clause must be preceded by a modifiable antecedent.

It can be omitted when it is used as an object in an attributive clause.

As long as we grasp these two points, we can easily master the above questions.

Supplement: I think the second sub-question of the 1 question can be selected if there is "what" in the option! !

I share my experience with you! !

* * * progress!

In the postscript, the respondent of "ぁめたまま" mentioned in your explanation that "the subject clause needs to use the leading word that, so it is correct to change ACD to how you have obeserved".

I have a different view on this! ! !

(1) Although that leads to the subject clause, that cannot be omitted. But how do we use two leading words in a clause?

(2) The nominal clause (as a relative word) guided by 2)that has neither any component nor practical significance in the clause, but only plays the role of connecting sentences. Therefore, whether it is added or not has no influence on the components of this clause. Then the sentence component "how How how you have observed" is incomplete in itself, so how can it be used as the subject of a clause? So this is not its job, it can't do it! ! ! !
