先看两个句子:
I don’t want to spend any more money than necessary.
I think it’s bigger than is necessary.
我的疑问:
1. 第一句用 than necessary, 第二句用 than is necessary, 两者有何区别?
2. 这是省略吗?是省略了什么成分?
二者在口语及书面语中应该都常见。than necessary 与 if necessary 似乎不同,后者等于 if it is necessary,而前者稍有不同。
第一句等于:I don’t want to spend any more money than it is necessary for me to spend.
第二句等于:I think it’s bigger than it is necessary for the thing to be.
