It is often difficult to decide on the inventor of certain inventions.
请问这里的 decide on 是什么意思呢?decide 及物不及物时意思不同吗?
▲表示决定做某事,decide on 后接动名词,与 decide 后接不定式意思大致相同,但 decide to do sth 比 decide on doing sth 更普通。如:
We decided on leaving. / We decided to leave. 我们决定离开。
He decided on going abroad. / He decided to go abroad. 他决定出国。
▲decide 用作及物动词时,可直接跟名词或代词作宾语,此时 decide sth 与 decide on sth 的用法如下(摘自《薄冰英语惯用法词典》第200页)
1. decide sth 意为“决定”“解决”,表示解决某个悬而未决的问题,运用范围较窄,能接的名词有限,一般接 question, case, argument, dispute, outcome, match, fate 等。……
2. decide on sth (sb) 意为“选定”“选用”,表示从几个事物或人中选定一个,运用范围广,可接多种名词。……
▲你的句子:It is often difficult todecide on the inventor of certain inventions.
大意为:决定某些发明的发明人通常并不容易。
