Question

________ his career as an actor he never gave up his hope of becoming a Hollywood star.

A．Throughout	B．Within
C．For	D．In

Answer 1

A

A　句意：在他整个演艺生涯中，他从未放弃成为好莱坞明星的梦想。throughout表示时间时，意为： during all of a particular period，from the beginning to the end，强调“在……的整个期间”；in和within都可表示“在……(时间)内”，但不能强调自始至终，故被排除；for表示时间，后需要一段时间，如for a year/month等。
