Unit vii verb combinations
Verbs are often followed by another verb.
I enjoy reading.
I didn’t choose to do this job.
I don’t want to go.
You deserve to getpromotion.
She denies sellingsecrets.
He doesn’t recall meeting him.
It can be difficult to know whether the second verb is a to-infinitive or ends with –ing.
Verb + verb + ing
The –ing form focuses on:
- `an action or state before the action of the first verb:
Sheadmitted taking a bribe.
He misses seeing his wife and children
She finished doing her accounts yesterday.
- the activity itself. The second verb functions like a noun.
Idislike travelling.
She recommended selling the shares now.
They have postponed launchingthe new model.
Some common verbs that are followed by –ing forms:
Admit appreciate contemplate give up involve
Deny enjoy consider carry on mean
Look forward to mind justify can’t stand remember anticipate resent detest recollect
Risk recommend delay miss
Jeopardize suggest put off avoid
Verb + TO + Infinitive
The to-infinitive form focuses on

She intends to complain.
They’ve decided to go ahead with the idea.
- a future situation:
They are planning to launch a takeover bid.
I’ve arranged to see the financial people tomorrow.

Some common verbs that are followed by to-infinitive forms:
Intend attempt promise plan guarantee claim
Mean try undertake arrange offer pretend
Want hope forget seem fail

Verb + Object + To-infinitive
When we talk about two actions performed by different people , the verbs are separated by an object:
Hedidn’t want me to attendthe meeting.
They do not allowyouto smoke at work.
A laptop enables people to work on a plane.
Some common verbs used with an object and a to-infinitive clause:
Advise allow ask cause challenge choose defy enable encourage
Expect forbid force help inspire instruct intend invite lead leave
Mean oblige order pay permit persuade prefer programme recruit
Remind teach tell train trust urge use warn
Verb +Object + verb +-ing
Some verbs are used with an object and a second verb ending in –ing:
Verbs used in this way may include:
Catch describe discover feel find hear imagine
Keep leave like listen to notice observe prevent(from)
Save see send set show watch
Her commentset me thinking.

The white knightpreventedthe company from being taken over.
Verbs of perception
Not all the action is seen or heard
I saw a man stealing some clothes from the store.
He watched the crowd leaving the stadium.
I heard a door banging repeatedly.
All of the action is seen or heard
I saw a man steal some clothes from the store.
He watched a crowd leave the stadium.
I heard a door bang once and then nothing.
Verb + Infinitive without To
A few verbs used in second position do not take to. These are let, make and have ( in the sense “cause to happen”)
We let them have a 10% discount.
Don’t make me laugh.
Could you have Mrs. Smithbring in the coffee now?
Verb + It + Object Clause
When the object of a verb is a clause, to-infinitive or ing-structure, we use it after the verb to introduce the clause:
I find it impossible to understand their culture.
The government regard it as unnecessary to harmonize taxation.
She feels it is necessary to send a copy to absolute everyone.
He found it worthwhile visiting the overseas subsidiaries.
Verb + For+To-infinitive
Some verbs are followed by the preposition for and its object, then to-infinitive.
Hearranged for his secretary to drive him to the airport.
I waited for him to get back in touch.
They called forthe Union to reconsider its strike action.
These verbs can be used in this way:
Appeal, apply arrange ask call opt
Pay plead vote wait wish yearn
Verb + Possessive +verb +-ing
It is possible to introduce a possessive pronoun or a genitive between the first and the second verb. Thus “ Please forgive me for asking” can be reformulated formally as “Please forgive my asking”. Other verbs that follow this pattern are:
That would entail our making a concession.
This will save our wasting time.
They have suggestedhis going to the symposium.
He’s looking forward to our coming.
Special Cases
Certain verbs are followed by either an Infinitive or another verb + -ing but the choice leads to a change in the meaning.
I will neverforgetmeeting Princess Diana. ( I will always remember)
I sometimes forget to wear my badge( =fail to remember).
I mean to see her later this weak.(= I intend to).
I could get a better job but it would mean moving.( =involve)

UNIT VIII PASSIVES
1. Compare the following two sentences: Your little boybrokemy kitchen windowthis morning.
That window was brokenby your little boy.
In the first sentence the person who does the action (your little boy) is the subject, and comes first; then we say what he did ( with the verb’broke’) and what he did it to ( the object ‘my kitchen window’). In the second sentence, the opposite happens: we start by talking about the window( the object of the first sentence has become the subject of the second sentence); then we say what was done to it, and who this was done by. The first kind of sentence, and the verb-form used in it are called “active”. The second kind of sentence and the form of the verb-form used are called “passive”.
2. The choice between active and passive constructions often depends on what has already been said, or on what listener already knows. We usually like to start sentences with what is already known, and to put “new” information later in the sentence. In the first example above the listener doesn’t know about the broken window, so the speaker makes it the object in the sentence. In the second example, the listener knows about the window – it is being pointed out to him, he can see it – so the speaker uses the passive construction; in this way he can put the window first, and keep the new information (who broke it) for later in the sentence. Another example: John’s just written aplay. This playwas probably written byMarlowe.
In the first sentence , John is somebody that the hearer knows; the news is that “ he has written a play”. The speaker prefers to put this at the end, so he begins with “John” and uses an active verb. In the second sentence, a passive structure allows the speaker to begin with “the play” ( which the hearer already knows about) and to put the news ( who wrote it) at the end.
3. We often prefer to use longer and “heavier” expressions at the end of a sentence, and this can be another reason for choosing a passive structure. Compare: Mary’s behavior annoyedme.I was annoyed byMary wanting to tell everybody else what to do.The first sentence can easily be active or passive. But if the second sentence was active, the subject would be very long (Mary wanting to tell everybody else what to do annoyed me). In this case, a passive structure is more natural. Passive structures are also used when we want to talk about an action, but we are not interested in saying who did it. E.g. Thosepyramids were built around 400 A.D.
Passives are very common in scientific writing, and other kinds of expression where we are most interested in events and processes: in things that happen. Active forms are more common in imaginative writing (novels, stories, etc.) and in other cases where we want to say a lot about the people who make things happen.
4. Note that meaning and grammar do not always go together. Not all active verbs have “active” meanings; not all passive verbs have “passive” meanings. If you say that somebody ”receives” something, or “suffers” you really mean that he has something done to him. The verb form is active but the meaning is passive. Some English active verbs might be translated by passives in certain other languages (She is sitting); some English passives would not be translated by passives in some other languages ( I was born....; English is spoken here).
5. A few active verbs can be used with passive meanings.
Your report reads well (= It is interesting to read your report)
The new Ford is selling badly.
This dressdoes up at the front.
It’s a pretty material, but it doesn’t wash.
Sometimes active and passive infinitives can be used with very similar meanings. E.g. There’s a lot of work to do/to be done.
After “need, want , require” active –ing forms can be used with passive meaning. ( My watch needs cleaning = to be cleaned).
When present participles (-ing forms) are used as adjectives, they usually have active meanings.( A crying child; the people taking part).
Past participles ( broken, invited) normally have passive meanings but there are a few exceptions. E.g. abroken window but a retired general; the people invited but fallen rocks.
6. Not all verbs can have passive forms. Intransitives (like “die, arrive”) cannot become passive; they have no objects, and so there is nothing to become the subject of a passive sentence.
FORMS
Passive forms are made with the different tenses of “to be” followed by a past participle. The tenses, and the rules for their use, are the same as for the active forms. Note , however, that we avoid saying “be being” and “been being” so that future progressive and perfect progressive tenses are very uncommon.
Present Simple: English is spoken here
Present Progressive: Excuse the mess: the houseis being painted.
Past Simple: Iwasn’t invited.
Past Progressive: I felt as if I was being watched.
Present Perfect: Has Mary been told?
Past perfect: I knew why I had been chosen.
Future Simple: You’ll be told in advance.
Future Perfect: Everything will have been done by the 26th.
Going to structures: Who’s going to be invited?
Modal structures: He ought to be asked.
Passive –ing forms also exist: E.g. She likes being looked at. Having been rejected by everybody, he became a monk.
USES
- Focusing on action
We use a passive construction when we are not interested in who performs the action or it is not necessary to know:
The datewas changed.
The missing file has been found.
He has been promotedto the post of Sales Director.
If we also want to mention who performs the action we can use a phrase beginning with “by”.
The decision was takenby the committee.
The missing file has been foundby one of the cleaners.
- focusing on information
In a passive sentence, the grammatical subject receives the focus:
The visiting delegationwas met by the president at the airport.
Here the visiting delegation, rather than the president, is in the centre of interest.
- describing a process or procedure
We use the passive because we are more concerned with the process itself than who carries it out. For example, there is a description of the wine-making process:
Wine is made from the fermented juice of grapes. Grapesare pickedat optimum sugar/acidity levels. After picking, the grapes are takento the winery,de-stemmed and crushed in a variety of presses. The juice isthen clarifiedby settling or by centrifuge, yeast and sugar are added and the wine is leftto ferment in tanks. When fermentation is finished the wine is poured into a clean tank to stabilise. It can then be filteredandbottled andleft to mature.
- writing in formal style
When writing in formal style ( e.g. reports, minutes of meetings) we often choose an impersonal style by using the passive and beginning sentences with “it”.
It was agreed to increase the share capital.
It was considered to be an unacceptable alternative.
It has now been decided to postpone the proposed construction.
Another common way of reporting what is said or thought is to use “it+passive+that-clause”.
Itwas agreedthat the share capital should be increased.
Itwas feltthat some economies had to be made.
Other verbs used in this pattern include:
Announce, claim, discover, estimate, expect, know, mention, propose, recommend suggest, think, understand.
- reporting unconfirmed situation
when the statement is speculative we use the passive of “say, think, consider, believe” followed by an infinitive. This structure is common n newspaper reporting.
The minister is saidto be in favor of decreasing corporation tax.
The board is thought to be in favor of a merger.
He is consideredto be the best chairman the company has ever had.
The terrorists are believed to want a new ceasefire.
- verbs with two objects
Many verbs such as “give, send, show, lend” can be followed by two objects, which usually refer to a person or thing.
She gave her sister a car.
When these verbs are used in passive, there are two possibilities.
Her sister was given a car.
The carwas givento her sister.
Most often in such cases the person becomes the subject of the passive voice.
I’ve justbeen sent a whole lot of information.
You were lent ten thousand pounds last year.
We were shown all the different ways of making whisky.
Other verbs used like this are “pay, promise, refuse, tell, offer”.
- sentences with object complements
After some verbs the direct object can be followed by an “object complement” – a noun or adjective which describes the object.
They electedhim president.
We regarded him an expert.
I madethe room beautiful.
These sentences can become passive.
He was elected president.
He was regardedto be an expert.
The room was made beautiful.
- sentences with clause objects
The object of a sentence can be a clause.
People believedthat witches communicated with devil
Nobody knewwhether there was gold in the mine.
Passive sentences can be made with “that” or “whether”-clauses as subjects. “It” is usually used as an introductory subject.
It was believed that witches communicated with devil
It was not knownwhether there was gold left in the mine.
- verbs with object + infinitive
Many verbs can be followed by an object and infinitive.
She asked me to senda stamped addressed envelope.
Everybody wantedDoris to bethe manager.
Verbs of “asking, ordering, allowing” can usually be used in the passive with a following infinitive.
I was asked to senda stamped addressed envelope.
Shewas told not to come back.
A few verbs are followed in the active by an object and an infinitive without “to”. Examples are “ hear, help, make, see”. In the passive , the “to-infinitive” is used. Compare:
I saw him come out of the house.
He was seen to come out of the house.
They made him tell them everything.
He was made to tell everything.
- verbs which can not be used in passive
Not all verbs can have passive forms. Intransitive verbs can not be used in the passive: since they do not have objects, there is nothing to act as a subject of a passive verb. Some transitive verbs cannot be used in the passive at least in certain of their meanings. Most of these are “stative “ verbs ( verbs which refer to states, not to action, and which have no progressive forms). They are : fit, have, lack, resemble ..... . E.g. Your mother lacks tact. ( we can’t say ‘tact is lacked....’).

UNIT IX MODAL VERBS
There is a group of auxiliary verbs which have a “dictionary” meaning. They are “ can, could, may, might, must, will, would, shall, should , need”. ( ‘Need’ can also be an ordinary non-auxiliary verb). These verbs are often called “modal auxiliaries”. They have several points in common which make them different from other verbs.
- modal verbs never show an action. They show only the attitude of a doer to an action.
Imust read this book.
- they are not used (except sometimes in the negative) to talk about things that are definitely happening, or have definitely happened. Modal verbs are used when we say that we expect the things to happen, or that events are possible, or necessary, or improbable, or when we say that things did not happen, or that we are not sure whether they happened.
I can’t swim.
She could be in London , or Paris, or Tokyo – nobody knows.
I may come tomorrow if I have time.
Youmight have told me he was ill.
- modal verbs have no “-s” in the third person singular; questions and negatives are made without “do”; they are followed by the infinitive without “to” of other verbs ( sometimes modal verbs are called “defective ones”).
You needn’t look at me like that.
Hemust be here at nine o’clock.
- modal verbs have no infinitives , and other expressions are used instead, when necessary.
I’d like to be able to skate.
You’re going to have to work harder.
- modal verbs have no past forms. “Could” and “would” are used with past meanings in some cases .
- modal verbs can be used with perfect infinitives to talk about things which did not happen, or which we are not sure about, in the past.
You should have told me at once.
Her car may have been broken down.
Some modal verbs have weak pronunciations, “Shall”, “will”, “would” and “should” have contracted forms, and all modal verbs can have contracted negative forms.
We’ll see you tomorrow evening.
I’d keep quiet if I were you.
You can’t help liking her.
It won’t make much difference if we’re late.
Each modal verb has at least two meanings. One use of all modal verbs is to talk about the possibility or probability of a situation or event. Some of these verbs are used to say that a situation is certain; others that it is probable or possible; others that it is impossible.
Certainty
Verbs used: shall, shan’t, will, won’t, must, can’t, couldn’t, wouldn’t, would.
I’llsee you tomorrow.
I shan’t be late.
It won’t rain this evening.
I told you wouldn’t be able to do it.
Ability
- saying that someone knows how to do something:
We use “can” to say that someone is able/not able to do something.
Our new divisional managercan speak four languages fluently.
He can’t drive, he’s never learnt how to do it.
We also use “can” to say that machines are able to perform certain tasks:
The new photocopiercan print out a whole book in less than five minutes.
- talking of a past ability
Hecould play the piano when he was five years old.
This sentence refers to an ability that was not limited to just one occasion. If we want to speak of one event we use “managed to” or “was able to”.
After six hours of negotiation, we finallymanaged to make some progress.
After some hours of negotiation, wewere finally able to make some progress.
The negative form is , however, possible for just one occasion:
We couldn’t get tickets for the opera – they were all sold out.
- indicating disapproval when something is or was not done
She could make more of an effort. (=she is able to, but doesn’t)
You could have told me beforehand – I needed to know. ( = you were able to , but didn’t).
Obligation, prohibition
- saying what is compulsory
We use “must” or “has/have to” to indicate what is compulsory in the present and future:
Any change in taxationmust be fair, fiscally responsible and must avoid simply shifting the burden from the rich to the middle class.
All travelers to China have to be in possession of a visa.
“must” can also be used in reported speech:
The London Chamber of Commerce and Industry said the government must act to tackle the capital’s traffic problems.
If something was necessary or obligatory in the past we use “had to” and we use “will have to” for the future.
When we lived in Sao Paulo wehad to learn some Portuguese.
We will have to evaluate the new procedure regularly.
The absence of future obligation is expressed by “will not/won’t have to”.
If we open a bank account in the Bahamas we won’t have to pay income tax.
- imposing an obligation on ourselves
We prefer to use “must” when we oblige ourselves to do something. We prefer “have to” when the obligation is imposed by other people or external circumstances.
I must remember to get in touch with Mr.Gonzales, I keep forgetting.
I must buy my wife a present before I go home.
We have towear a uniform at work, it’s not our choice.
I enjoy going to conferences unless Ihave to make a presentation.
- freedom to choose
If you “do not have to do something”, there is no obligation – if you are free to act.
I can work from home so I don’t have to go into the office very often.
- saying that something is prohibited
We use “must not” to say that something is forbidden or very unacceptable.
Passengers must not smoke during take –off.
You mustn’t enter a joint-venture unless both parties benefit from the deal.
“cannot “ and “ may not” are also used if something is forbidden because of a rule or a law.
Retailerscannot/may not sell below cost price in some countries.
Possibility
- expressing possibility
