Question

因为字数限制我写在“问题补充”里了.
what we must do is encourage the strengths and diminish the weaknesses as soon as possible.
是不是要加个to才对?即what we must do is to encourage才对?还有如果前面加了to,后面and的后面要不要再加to了?即and to diminish the weaknesses才对?

Answer 1

表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、从句来充当,动词不能作表语.因此,你的理解是正确的.根据此句的意思,应当用不定式作表语.and连接的是两个并列的成分,此名中连接两个不定式,但and后的to要省略.
