    ➡️ It's easy to understand.// The kid wants to play. // She has to give the toy back.//  

    * You'll tell me: "Oh, quite easy!"  It is, indeed! Here are three simple infinitives

    or rather three "present infinitives" in the affirmative form! 



    ➡️ A little more "difficult",  a negatif infinitive... Be careful! 

    The order of the words is extremely important

    - We hope not to be late.// It's easy not to find your way... // I'd like you never to go away... 

    You must be starting to guess that, this time, the "lesson" will be about 

    INFINITIVES... ( WHAT?  There are several forms of INFINITIVES!  A real nightmare!  )


    1) PERFECT INFINITIVE: (to have + past participle ) 

    The perfect infinitive refers to a time before that of the preceding verb:   

    - He seems to have started running now! 

    - "Look! The rain seems to have stopped!" 

     In English, the perfect infinitive is always built with the auxiliary HAVE.



    -   In the negative form, the word order must be:  "NOT+ TO+ HAVE+ Past participle."

    "I'm surprised not to have heard her cry..." 



    - With modal auxiliaries (modals), the perfect infinitive is used without TO.

    He must have been tired after such a journey! 

    - The perfect infinitive isn't used after:  after, before, without... 

    Before reading her letter, I already knew what she wanted to say...

     Thank you for helping me/ for lending me...

    2) THE INFINITIVE in the PASSIVE: the auxiliary used to build a passive form is TO BE:

    (To) BE+ past participle. 

    The passive infinitives shift the focus of the sentence towards the object

    when the speaker decides to put a certain emphasis on it. 

    - He wants to be helped for everything. 

    - The child is not to be left alone. 




    * The 'passive infinitive' is used with modals

    - This machine must be repaired today. 




    3) THE INFINITIVE in - ing: (to) be +V ing.

    The regular present perfect in V+ing tense structure follows the “to” and makes it perfect

    continuous infinitive - “to+ have + been + Present Participle.

    The sense of continuation is added to the perfect infinitive without the obligation to state

    the time frame as in the perfect continuous tense structure. 

    - He swore not to be lying during the testinony... 

    - Olivia seems to be reading a lot these days... 


    Let's be frank.... It's quite easy, isn't it? Now, go for the test!  The FORCE is with you!
