1.The shy boy appeared in the classroom,_____ his mother,who was leading him _____hand.
A.你可以把句子補(bǔ)全為：
The shy boy appeared in the classroom and he followed his mother,who was leading him by the hand.
這時(shí)你會(huì)看到and he followed his mother中的he 就是the shy boy,為了避免重復(fù),把后面的and he followed 變?yōu)榉侵^語following .
B.by the hand 是固定用法.
又如：The man hit Bob on the head.
Don't pull me by the collar.
