UNIT 89. All, every and whole
A. All and everybody/everyone
We do not normally use all to mean everybody/everyone:
* Everybody enjoyed the party. (not 'All enjoyed...')
But note that we say all of us/you/them, not 'everybody of...':
* All of us enjoyed the party. (not 'everybody of us')
B. All and everything
Sometimes you can use all or everything:
* I'll do all I can to help. or I'll do everything I can to help.
You can say 'all I can'/'all you need' etc. but we do not normally use all alone:
* He thinks he knows everything. (not 'he knows all')
* Our holiday was a disaster. Everything went wrong. (not 'All went wrong')
We use all in the expression all about:
* They told us all about their holiday.
We also use all (not 'everything') to mean the only thing(s):
* All I've eaten today is a sandwich. (= the only thing I've eaten today)
C. Every/everybody/everyone/everything are singular words, so we use a singular verb:
* Every seat in the theatre was taken.
* Everybody has arrived. (not 'have arrived')
But we often use they/them/their after everybody/everyone:
* Everybody said they enjoyed themselves. (= he or she enjoyed himself or herself)
D. All and whole
Whole = complete, entire. Most often we use whole with singular nouns:
* Did you read the whole book? (= all the book, not just a part of it)
* She has lived her whole life in Scotland.
We normally use the/my/her etc. before whole. Compare whole and all:
the whole book/all the book her whole life/all her life
You can also use: a whole ....
* Jack was so hungry, he ate a whole packet of biscuits. (= a complete packet)
We do not normally use whole with uncountable nouns. We say:
* I've spent all the money you gave me. (not 'the whole money')
E. Every/all/whole with time words
We use every to say how often something happens. So we say every day/every Monday/every ten minutes/every three weeks etc.:
* When we were on holiday, we went to the beach every day. (not 'all days')
* The bus service is very good. There's a bus every ten minutes.
* Ann gets paid every four weeks.
All day/the whole day = the complete day from beginning to end:
* We spent all day/the whole day on the beach.
* He was very quiet. He didn't say a word all evening/the whole evening.
Note that we say all day (not 'all the day'), all week (not 'all the week') etc.
Compare all the time and every time:
* They never go out. They are at home all the time. (= always--not 'every time')
* Every time I see you, you look different. (= each time, on every occasion)

UNIT 90 Each and every
A. Each and every are similar in meaning. Often it is possible to use each or every:
* Each time (or Every time) I see you, you took different.
* There's a telephone in each room (or every room) of the house.
But each and every are not exactly the same. Study the difference:
#1 We use each when we think of things separately, one by one.
* Study each sentence carefully. (= study the sentences one by one)
Each is more usual for a small number:
* There were four books on the table.
Each book was a different colour.
* (in a card game) At the beginning of the game, each player has three cards.
#2 We use every when we think of things as a group. The meaning is similar to all.
* Every sentence must have a verb. (= all sentences in general)
Every is more usual for a large number:
* Carol loves reading. She has read every book in the library. (=all the books)
* I would like to visit every country in the world. (=all the countries)
Each (but not every) can be used for two things:
* In a football match, each team has 11 players. (not 'every team')
We use every (not each) to say how often something happens:
* 'How often do you go shopping?' 'Every day.' (not 'each day')
* There's a bus every ten minutes. (not 'each ten minutes')
B. Compare the structures we use with each and every:
#1 You can use each with a noun: each book, each student
You can use each alone (without a noun):
* None of the rooms was the same. Each was different. (= each room)
Or you can use each one:
* Each one was different.
You can say each of (the.../these... etc.):
* Read each of these sentences carefully.
* Each of the books is a different colour.
Also each of us/you/them:
* Each of them is a different colour.
#2 You can use every with a noun: every book, every student,
You can say every one (but not every alone):
* 'Have you read all these books?' 'Yes, every one.'
You can say every one of ... (but not 'every of ...')
* I've read every one of those books. (not 'every of those books')
* I've read every one of them.
C. You can also use each in the middle or at the end of a sentence. For example:
* The students were each given a book. (=Each student was given a book.)
* These oranges cost 25 pence each.
D. Everyone and every one
Everyone (one word) is only for people (='everybody'). Every one (two words) is for things or people, and is similar to each one (see Section B):
* Everyone enjoyed the party. (=Everybody...)
* He is invited to lots of parties and he goes to every one. (=to every party)

UNIT 91 Relative clauses (1)--clauses with who/that/which
A. Look at this example sentence:
The woman _who lives next_(relative clause) door is a doctor.
A clause is a part of a sentence. A relative clause tells us which person or thing (or what kind of person or thing) the speaker means:
* The woman who lives next door ... ('who lives next door' tells us which woman)
* People who live in London ... ('who live in London' tells us what kind of people)
We use who in a relative clause when we are talking about people (not things). We use who instead of he/she/they:
the woman--she lives next door--is a doctor
-> The woman who lives next door is a doctor.
we know a lot of people--they live in London
-> We know a lot of people who live in London.
* An architect is someone who designs buildings.
* What was the name of the man who lent you the money?
* Anyone who wants to do the exam must enter before next Friday.
You can also use that (instead of who):
* The man that lives next door is very friendly.
But sometimes you must use who (not 'that') for people - see Unit 94.
B. When we are talking about things, we use that or which(not 'who') in a relative clause:
where is the cheese? - it was in the fridge
-> Where is the cheese that was in the fridge?
-> Where is the cheese which was in the fridge?
* I don't like stories that have unhappy endings. (or ... stories which have ...)
* Barbara works for a company that makes washing machines. (or ... a company which makes...)
* The machine that broke down has now been repaired. (or The machine which broke
down ...)
That is more usual than which. But sometimes you must use which (not 'that')--see Unit 94.
C. You cannot use what in sentences like these:
*. Everything that happened was my fault. (not 'Everything what happened...')
What = 'the thing(s) that';
* What happened was my fault. (=the thing that happened)
D. Remember that in relative clauses we use who/that/which instead of he/she/they/it. So we say:
* Do you know the woman who lives next door? (not '...the woman she lives next door')

UNIT 92 Relative clauses (2)--clauses with or without who/that/which
A. Look again at these example sentences from Unit 91:
* The woman [who] lives next door is a doctor. (or The woman that lives...)
[The woman] lives next door. who(= the woman) is the subject
* Where is the cheese [that] was in the fridge? (or ... the cheese which was...)
[The cheese] was in the fridge. that(= the cheese) is the subject
You must use who/that/which when it is the subject of the relative clause. You cannot say 'The woman lives next door is a doctor' or 'Where is the cheese was in the fridge?'
B. Sometimes who/that/which is the object of the verb. For example:
*. The woman [who] I wanted to see was away on holiday.
I wanted to see [the woman]. who(= the woman) is the object. I is the subject
* Have you found the keys [that] you lost?
You lost [the keys]. that(= the keys) is the object. you is the subject
When who/that/which is the object, you can leave it out. So you can say:
* The woman I wanted to see was away. or The woman who I wanted to see...
* Have you found the keys you lost? or ... the keys that you lost?
* The dress Ann bought doesn't fit her very well. or The dress that Ann bought...
* Is there anything I can do? or ... anything that I can do?
Note that we say:
the keys you lost (not 'the keys you lost them')
the dress Ann bought (not 'bought it')
C. Notice the position of prepositions(in/at/with etc.) in relative clauses:
do you know the woman?--Tom is talking [to] her
-> Do you know the woman (who/that) Tom is talking [to]?
the bed--I slept [in] it last night - wasn't very comfortable
-> The bed (that/which) I slept in last night wasn't very comfortable.
* Are these the keys (that/which) you were looking for?
* The woman (who/that) he fell in love with left him after a few weeks.
* The man (who/that) I was sitting next to on the plane talked all the time.
