Question

When the millionaire was young, he was very poor. Only by doing part­time jobs during the summer holiday ________ afford to pay his college fees.

A．he could	B．could he
C．can he	D．he can

Answer 1

B

选B　考查倒装和时态。句意：当这位百万富翁年轻的时候，他非常穷。只有在暑假做兼职工作他才能付得起大学的学费。“only＋状语”置于句首时，句子应用部分倒装，此处说的是过去的事情，故选B。
