I still have some concerns with having both gerunds and infinitives in a sentence, are these grammatical correct, " he's playing with fire that's going to burn him" and "she's begging me to buy her a car" and " I want to tell him to start preparing to play at Wembley this evening. " thanks

Hello Timmosky,

Yes, those are all correct.

Best wishes,

Can you use an infinitive with the future tense and perfect tenses( present perfect, future perfect) e.g, "I will have to buy the game tomorrow. (infinitive in future tense)", "I have agreed to do the job for you. ( infinitive in present perfect)", "I will have agreed to marry her by November (infinitive in future perfect)." Thanks

Hello Timmosky,

All of your sentences are grammatically correct, but I wouldn't describe the grammar as you have. Instead, I'd say the first is a future form ('will') + the expression 'have to + infinitive' as a complement. The second is  the verb 'agree' in the present perfect with an infinitive complement after it. The third is similar except the tense is future perfect.

All the best,

Hello Team,
I appreciate what you guys are doing here and glad to announce that my English has improved a lot over the last two months. And I'm grateful to you guys for your support during this time period.
I feel very confused whenever I'm using to+infintive and ing verbs (gerunds), as in the exercise above in almost every question it looked that both could be used. So I follow my instinct and was able to get right most of them (10 out of 13).
Now it looks like that one can only get good at this by practicing and using language more and more. Or is there any other way around? Maybe memorizing them?
Regards
Sajad.

Hello Sajad,

Whether a partcular verb is followed by a gerund or a form of the infinitive (or whether both are possible) is quite arbitrary, I'm afraid, so you just have to remember them. Of course, practice exercises will help you to do this.
