Inversion is used in conditional sentences
where if is replaced by had, were and
should.
Should he remember his own name, we’ll be able
to help him = If he remembers his own name, … Should you not wish to join them, you must let them know before 4 o’clock = If you don’t wish

Trang 4Present Tense is used in IF Clause instead
of will, shall to refer to Future.

But: Will can be used in IF Clause with
the meaning of willingness, insistence & a
result of the action of the Main Clause.

= If you are willing to sell your car, …

Present Subjunctive is used in IF Clause
to emphasize an uncertainty

WISHES
Wish + to-infinitive
When we use wish followed by a verb in
the to-infinitive form, wish means the same
as want, but it is more formal We do not
normally use wish in the continuous form
when we use it with a to-infinitive:
I wish to speak to Mr Hennessy, please
Not: I’m wishing to speak to …
We don’t use a that-clause after wish when
it is a more formal version of want: I wish to visit you in the summer, if possible.Not: I wish (that) I visit you in the summer …
We can use an object (underlined), before
the to-infinitive: I did not wish my family to know about Sara, soI told them nothing When we use an object after wish, we must
also use a verb in the to-infinitive form
Alternatively, we can say want or (more
politely) would like:
We wish to have a table near the window, please (or We would like a table near the window, please.)
Not: We wish a table near the window …
Wish + Indirect Object + Direct Object
We use wish with two objects, an indirect
object + a direct object, for expressions of
good wishes and hopes that good things will
happen to people:
I wish [IO] you [DO] success in your new job.
I’ve got my driving test tomorrow Wish
[IO] me [DO] luck!
We wish [IO] you [DO] a long and happy
life together.
We wish [IO] you [DO] A Merry Christmas.

be as it used to be

PRESENT S + Ved/2
S + were

PAST Past Perfect I wish that she had not failed in

I wish you hadn’t told me how the film ends You’ve spoilt it for me (You told me how the film ends; it would have been better if you had not told me.)
Wish + verb forms in the that-clause
- The verb forms we use in that-clauses after wish are similar to the verb forms in conditional clauses after if We use a past verb form for past, present and future meanings

It would be good if I knew how to use this DVD
player
I wish I knew how to use this DVD player
It would have been better if I had not said it I wish I hadn’t said that I can see I’ve upset you Sorry
- In informal situations, we can use wish in the continuous form like this

Warning:
- We use hope, not wish, when we want something to happen in the future or when we want
something to have happened in the past

Not: I wish the weather’s fine tomorrow
I hope they didn’t miss their flight
Not: I wish they didn’t miss their flight
