Identify the form of the underlined verb in the sentence:Last night,…

The correct answer is Option (3) → Base form without “to”

Here “saw a shooting star” is followed by “cross”, with no “to” before it.

Option	Form and use	Example
(1) To-verb (infinitive)	has “to” before the base form (to cross). There is no “to” before “cross” here	We wanted to cross the river by boat.
(2) Present participle	an -ing form that is part of a continuous verb or describes a noun. “Cross” has no -ing ending	The children are crossing the road with the guard.
(3) Base form without “to” (answer)	the simple form of a verb (go, sing, cross), with no “to”, no -ing and no -ed; it can follow let, make and see + person or thing	Our teacher made us read the poem aloud.
(4) Gerund	an -ing word used as a noun. “Cross” has no -ing ending	Crossing the busy road needs care.
