Hi sayali,
Adam answered a very similar question about item 6 below, so please see his reply.
There is no one simple rule about when to use the -ing versus to + inf. form. You simply have to learn which verbs are followed by which forms. This is a challenging thing to do so practicing a lot helps.
I hope this helps.

I think that it is not very bad exercise!))

avoid                                             V  + ing

agree                                            to+infinitive

is that a rule ??

Hello goloconda!
There are a few exceptions. Suggest + v-ing is fine, but you can also use suggest object verb, as in I suggest you do this. Tell also needs an object (it is transitive when used like this) - He told me to do this. Advise can use either form - I advise studying English every day, or I advise you to study English every day. I advise to study English is defintiely wrong, though.
Unfortunately, like a lot of English, it's only a rule until it isn't! However, even if you make a mistake, it probably won't affect the meaning, so don't worry too much about it.

In your example:
I suggest you do this
what is its difference with some sentences like this:
I suggest you to do this


Hello eliyas.1368,

'Suggest' is not followed by an infinitive with 'to', so the second sentence is incorrect.

  1. Students are trained for their future
  2. Students are to be trained for their future

Are these two sentences grammatically correct and are there any different between these two sentences?
Thank you.

Hello bimsara,

Both sentences are grammatically correct.  The first is an example of a present tense and describes a situation which is generally true.  The second is an example of a future form [be + to infinitive] which describes a planned or set future action.

I hope that clarifies it for you.

Hi teacher, i was wondering if you could answer to my questions:
1) i may say:Students have to trained for their furure , what is the difference? if there is one.
2)as well i noticed in another part that asked was used with the subjunctive, i did not know it might be used like there. the verbs that i know are:suggest,propose,insisted and demand. is that right?

Hi rosario70,

1) This sentence is not grammatically correct. Perhaps you meant 'Students have to be trained for their future', which would have a meaning of obligation - something which is necessary. The difference with '...are to be trained...' is that where the first sentence describes obligation, the second described a plan or expectation.

2) It is possible to use 'ask' with the subjunctive. For example:

I ask that he leave now.

However, this sounds very old-fashioned. It is not a form which is used in everyday language, though you may come across it in certain archaic phrases, such as traditional parliamentary or legal turns of phrase.
