Noun Clauses and Auxiliaries Advanced Level Test – Quiz (Online Exercise With Answers) 1

A question tag matches the subject and auxiliary of the last main clause, here it turned out. Turned out is past simple and positive, so the tag uses negative did: didn't it? Not weren't we, because the tag refers to it (the city), not to the earlier clause we were hoping.

The subject of the main clause is problems and the auxiliary is can. A positive statement takes a negative tag, and the pronoun for problems is they: can't they? Not can we, because we is the subject of the relative clause that we can't solve, not of the main clause.

Hardly ever gives the sentence a negative meaning, so the tag must be positive. The verb joins is present simple, so the tag uses does: does she? Not doesn't she, which would only follow a positive statement.

No longer trusted is a negative idea in the past simple, so we add another person with neither/nor + did + subject: and neither did anyone else. Not nor had, because the main verb trusted is past simple, not past perfect; the past perfect hadn't been able is only in the time clause.

With I don't think / I don't believe + clause, the tag refers to the reported clause, not to I. The negative is moved onto think, so the clause she will be considering counts as negative and takes a positive tag: will she? Not do I, because the speaker is giving an opinion, not asking about himself.

The main clause is You wouldn't mind. It is negative with the auxiliary would, so the tag is positive: would you? Not did you: the past form turned is in the if-clause (unreal past for a polite request) and does not decide the tag.

After I think + clause, the tag usually refers to the clause after think: they are crazy. The clause is positive present with are, so the tag is aren't they? Not weren't they, because the quoted words are in the present tense, even though the reporting verb said is past.

As + subject + auxiliary compares two people doing the same thing. Passed away is past simple, so the auxiliary is did: as his father did (= in the same way his father had died). The other options are ungrammatical or don't match the tense.

The main verb is is, so we add another person with so is + subject: so is his wife. Not so do his father, because the auxiliary must match is (and father would need does).

The tag refers to the main clause, He explained, not to the reported clause. Explained is positive past simple, so the tag is didn't he? Not could he, because couldn't belongs to the reported clause.

The window was broken is a positive passive sentence with was, so the tag is wasn't it? Not didn't it, because the auxiliary in the statement is was, not did.

The structure Just as X ..., so + auxiliary + subject shows two similar facts. The verb is is, so we say so is his sister. The other options don't complete the Just as ..., so ... pattern.

After a negative statement we add another subject with neither + auxiliary + subject. The auxiliary must match the first clause: could not play → neither could Schalke. The other options either use the wrong auxiliary or don't express 'also not'.

The first gap starts a non-defining relative clause about the most important lesson, so we need which, after a comma. The second gap introduces a noun clause after is, so we need that: which is that a competitive economy requires ... Not what, because what can't follow a noun as a relative pronoun.

The subject Everybody takes the pronoun they in a tag. Told is positive past simple, so the tag is didn't they? Not didn't he: his belongs to the object, not the subject.

After said, we can keep the present tense when the fact is still true. The frog is still the first lungless frog known to science and still belongs to a short list, so we use is / joins. Not was / had joined: the joining happens at the same time as the discovery, so the past perfect is wrong.
