◆技巧点拨

only后接现在分词或不定式都可表示结果，但only doing是一般用语，only to do则表示意想不到的结果。动词、介词后面要求接名词或动名词做宾语，如果所给动词后有宾语，则将所给动词变为动名词，如果所给动词后无宾语，则将所给动词变为名词。

(1)Jack went swimming in the lake,only _______________(have)great fun with his fellows.

(2)Jack hurried to Tom?s home,only _______________(find)Tom was out and the door was locked.

(3)He was good at _______________(persuade)others to give up their ideas.

(4)They just stood there and stared at the stranger in _______________ (amaze).

句(1)单纯表示结果，用having。句(2)的结果是Jack意想不到的，用to find。句(3)的persuade前有介词，后有宾语others，应填入动名词persuading。句(4)前有介词，后无宾语，应填入名词amazement。
