       He turned on Florence¾ and bade her leave the room (Dick-
ens). He stood¾ beside a bush of pale Michaelmas daisies, watching
the last bees crawl into the hive (Lawrence). A few light taps upon the
pane made him turn to the window (Joyce). Andrew observed her
hurry off... (Cronin).
       Note. — All the verbs in b) and c) require an infinitive with to
when they are used in the passive voice:

great speed. He was made to come.
       d) After the verb to know in the sense of to experience, to
observe:

I had never known her pretend (Snîw).
       e) After the verb to help the infinitive is often used without to:
       I helped Mrs. Thompson take off her coat (Braine). I want to
help you keep him (Galsworthy). I’ll help you dry up... (Cusack).

have, would rather (...than), would sooner (...than), cannot but (can
but), does nothing but.., need scarcely (only, hardly):
       She does nothing but grumble. You need only give me a few
hints. I cannot but agree with you upon that subject. I need scarcely
tell you how important it is. I would rather not go (Bronte). «We’d
better take shelter,» said she (Maugham). Would you have me tell
her a lie (Sheridan).
       g) The particle to is dropped in special questions beginning with
why when the infinitive has the force of a predicate:
       Why not go to the cinema? Why not start earlier? But why not
tell them? (Galsworthy).
