Congratulations - you have completed Grammar Test 100. You scored %%SCORE%% out of %%TOTAL%%. Your performance has been rated as %%RATING%%

Your answers are highlighted below.

Question 1

This _____ the fourth time you’ve asked me the same difficult question.

A	had to be
B	must be
C	to be
D	have been

Question 1 Explanation:

Must be expresses a logical conclusion about the present: the speaker is almost sure this is the fourth time. Not had to be, which refers to the past and doesn't fit you've asked.

Question 2

He told the police that he _____ there since March.

A	not be
B	haven't been
C	wasn’t
D	hadn’t been

Question 2 Explanation:

In reported speech after a past reporting verb (told), the present perfect usually moves back to the past perfect: hadn't been. Since March shows a period up to that past moment. Not haven't been, because the subject he needs has, not have.

Question 3

I’m not going to miss the chance of seeing this performance _____ it is.

A	however expensive
B	although expensive
C	nevertheless expensive
D	how expensive

Question 3 Explanation:

However + adjective + subject + verb means 'it doesn't matter how': however expensive it is. Not how expensive, which is a question or exclamation form and doesn't give the meaning 'no matter how'.

Question 4

She demanded that she _____ given the exact figures.

A	be
B	are
C	were
D	have

Question 4 Explanation:

After verbs like demand, insist and suggest, formal English uses the subjunctive: the base form be for every subject (She demanded that she be given…). Not were, which is used after wish or if, not after demand.

Question 5

No sooner _____ the match than flames shot across the floor.

A	did he drop
B	he dropped
C	he had dropped
D	he drops

Question 5 Explanation:

When a sentence starts with the negative expression No sooner, the subject and auxiliary are inverted: No sooner did he drop (or had he dropped) … than …. Not he had dropped, because the word order must be inverted.

Question 6

Not until now _____ popularly recognized that man is destroying his environment.

A	it has become
B	it becomes
C	does it become
D	has it become

Question 6 Explanation:

Not until now at the start of a sentence needs inversion, and now shows a situation up to the present, so we use the present perfect: has it become. Not does it become, because the present simple doesn't fit until now.

Question 7

Not for one moment _____ my friend’s innocence.

A	I doubted
B	I did doubt
C	did I doubt
D	I doubt

Question 7 Explanation:

The negative phrase Not for one moment at the beginning causes inversion with an auxiliary: did I doubt. Not I did doubt, because the subject must come after the auxiliary.

Question 8

Hardly _____ the harbour when a storm broke out.

A	had we left
B	we had left
C	we left
D	we did leave

Question 8 Explanation:

Hardly … when describes one action happening just after another. Hardly at the start needs inversion and the past perfect: Hardly had we left … when …. Not we had left, because the word order must be inverted.

Question 9

You will pass the exam _____ you get over 50% in each section.

A	provided
B	unless
C	so
D	otherwise

Question 9 Explanation:

Provided means 'only if': you will pass on the condition that you get over 50%. Not unless, which would mean 'if you don't get over 50%', and that makes no sense.

Question 10

There will be even greater unemployment _____ the government radically alters its policies.

A	provided
B	unless
C	as if
D	in case

Question 10 Explanation:

Unless means 'if … not': unemployment will grow if the government does not change its policies. Not provided, which would give the opposite meaning.

Question 11

I have taken out life insurance to protect my wife and children _____ something should happen to me.

A	unless
B	otherwise
C	in case
D	provided

Question 11 Explanation:

In case means 'as a precaution against something that might happen': the insurance is there if something happens. It is often followed by should. Not provided, which means 'only if' and states a condition, not a precaution.

Question 12

We’ll have a good crop of beans this summer _____ an unexpected frost damages the plants.

A	unless
B	if
C	provided
D	so

Question 12 Explanation:

Unless means 'if … not': the crop will be good if a frost does not damage the plants. Not if or provided, which would mean the frost helps the crop.

Question 13

The east of Argentina is agricultural, _____ the west is industrialized.

A	whereas
B	because
C	so
D	since

Question 13 Explanation:

Whereas connects two contrasting facts: the east is agricultural, but the west is industrialized. Not since, which gives a reason, not a contrast.

Question 14

They would rather cut down on a few luxuries now _____ not be able to go away on holiday in the summer.

A	than
B	on
C	to
D	for

Question 14 Explanation:

The structure is would rather + base verb + than + base verb: would rather cut down … than not be able to go. Than introduces the less preferred option.

Question 15

The government aims _____ inflation by at least 20% this year.

A	reducing
B	to reduce
C	reduce
D	reduced

Question 15 Explanation:

The verb aim is followed by to + infinitive: aim to reduce. Not reducing; we say aim at reducing, but without at the infinitive is needed.

Question 16

“Don’t go out alone after dark in that city, Tom,” said Martha. Martha _____ Tom not to go out alone after dark in that city.

A	said
B	promised
C	threatened
D	warned

Question 16 Explanation:

Martha is telling Tom about a danger, so the reporting verb is warn: warn someone not to do something. Not said, because say cannot be followed directly by a person + not to.

Question 17

They prohibited him _____ going in.

A	from
B	to
C	for
D	in

Question 17 Explanation:

The pattern is prohibit someone from doing something: They prohibited him from going in. The -ing form after the gap shows a preposition is needed, not to.

Question 18

I have dissuaded Mary _____ involving the police.

A	from
B	to
C	in
D	for

Question 18 Explanation:

Dissuade means 'persuade someone not to do something', and the pattern is dissuade someone from doing something. Not to, which follows persuade, not dissuade.

Question 19

The guard prevented the prisoner _____ escaping.

A	for
B	to
C	from
D	than

Question 19 Explanation:

The pattern is prevent someone from doing something: The guard prevented the prisoner from escaping.

Question 20

Life is full of secrets, many _____ will never be explained.

A	of where
B	of whose
C	of whom
D	of which

Question 20 Explanation:

In a non-defining relative clause about things, we use many of which (secrets, many of which will never be explained). That can never come after a preposition. Not of whom, which is used for people, not things.
