Ex. 1. Study the following grammar.


Some of the questions in ex. 1 on p. 110 are difficult to answer (e.g. questions 4, 5, 7, 11 and 17) because we don’t know exactly what happened and how it oc- curred. In such cases it’s a good idea to use modal verbs of probability. Study the grammar material given below.

Modal Verbs of Probability


Modal verbs must, can’t, could, may, might and some others can be used to say that a situation is (or was) certain, impossible or probable.



Degrees
of certainty

About the present About

the past

90 % certain

He must be a millionaire now.

He must have been crazy when
he decided to fly to Moscow.

90 % certain

He can’t be in jail.

There can’t have been so many
strange coincidences!




50 % certain

He could still be very famous.

He could have calculated all the
risks involved.

50 % certain

He may be writing his memoirs
now.

His plane may have been shot
down.

30 % certain

He might be planning another
flight to Russia.

He might have become a profes-
sional pilot.



Note: Do not use may and might in questions and negative sentences. Use
could(n’t) or the phrase be likely:
e.g. Could it be that he wasn’t identified by Air Defense? It is unlikely that he served his full time in jail.
After modal verbs of probability different forms of the infinitive can be used:



Simple Infinitive



V1

To talk about the present or
future

He must be very famous. He may visit Moscow again one day.

Continuous Infinitive



be + V-ing

To talk about an action hap-
pening now

He might be planning
another flight to Russia.

Perfect Infinitive



have + V3

To talk about the past

Rust’s flight must have
damaged the reputation of the Soviet military.

Perfect
Continuous Infinitive



have been + V-ing

To emphasize
the duration of the past action

He could have been fly- ing at a very low altitude.



Simple Passive Infinitive

be + V3

To talk about the present or future in the passive voice

He may be considered as one of the greatest ad- venturers.
He could be invitedto
come to Russia.

Perfect
Passive Infinitive



have been + V3

To talk about the past in the
passive voice

He may have been injured
or even killed.
