Comments
Hello! I would like to ask what is the meaning of to + verb in the below sentence: "Greece to put sanctions on Turkey"
Hello DesKal,
This looks like a newspaper headline. Words are often omitted from headlines to save space. In this case, I expect the full sentence is 'Greece is to put sanctions on Turkey'. In formal speaking and writing, 'be' + infinitive can be used to express official planned actions (such as those carried out by a government).

Hi sir,
1.You seem nervous.
2.You seem to be nervous.
What is the difference between
the two sentences. With to be and
without to be.
Hello Luke warm
2 is the full form, but very often people omit 'to be' and use just 1. There is no difference in meaning.

Hi sir,
Please explain why there is "to be"
in following sentence. What does
"to be" mean.
In the following sentences does "to be" functioning as verb or adjective.
1. I didn't claim to be an authority.
2.The present is a gift, and I just want to be.
3.the duty of every athlete to be aware of what he or she is taking.
4. She is learning to be more discipline.
Hello Luke warm
Re: 1, the verb 'claim' is often followed by a noun or a phrase beginning with a 'to' infinitive. 'to be' is not adjectival here. The same is true of 'learn' in sentence 4.
I'm afraid that sentences 2 and 3 are grammatically incorrect. If you put 'is' before 'to be' in 3, then the phrase 'to be aware ...' is a nominal (noun-like) complement of the verb 'is'.

Hello everyone! I'm often confused...
I mean, i dont really know when i should use a verb in ing form and when to+infinitive.
For example: I'm really tired. I'm ready to go to bed.
I'm really tired. I'm ready going to be.
This one is just for example, there are many. So what is the difference?
Thanks
Hello amanrihana,
There are some verbs which are followed by to + infinitive and others which are followed by -ing.
I'm afriad there's no way to tell what any particular verb is followed by – you just have to memorise the patters.
Fortunately, we have pages on these to help you:
Verbs followed by the infinitive
Verbs followed by the '-ing' form

Hello
Sir You have explained before that there is no need to differentiate if Nonfinite is working as modifier or a noun, we just need to figure out correct use of infinitive/infinitive phrase vs ing phrase.
But still since i want to understand exactly why and how we are using an infinitive/ing thus following questions, please help/just verify:
-I want to sing (answers what) noun, correct
-I heard him sing/singing- as adjective modiying objective pronoun
-I study to learn(answers why/infinitive of purpose ) - Adverbial modifier of verb study
- he teaches people just to help - Adverbial modifier (answers why) not an adjective of people
-I want him to sing a song- Adjective modifier/adj clause. Providing more info about objective pronoun him.
-Doctor prescribed him to take medicine - Adjective modifier 'him'(unnatural English but just to understand from grammars point of view)
-He is prescribed to take medicine - Adjective modifier of he/predicate nominative.
-Different prospects are studied to learn more about the universe - Adverbial modifier fo studied.
thankyou
Sir, My approach is if it answers what(as verbs object) then its a noun, if it answer why when who which how what about a noun/pronoun than an adjective, if modifies an adjective or verb by answering why what when how than is an adverb, is this correct?
Also can participles work as adverbial modifiers, i read pariticiples cannot be adverbial modifiers but i think it can for eg. He came screaming(adverb) into the room, he is feeling ignored(adverb) or he died aged(adverbial modifier) 80, so we cam use participles as adverbial mod. right?
Thanks
