Question

这个想法很不错，但还需要试验一下。英文翻译里The idea seems good but it needs to be tried out.

Answer 1

sth need/requie/want +to be done
因为it (The idea )和try 的关系是被试一下所以用被动也可以用动名词的主动表被动
e.g The bike needs/wants to be repaired .
=The bike needs/wants repairing.
Need, want, require（要求，需要）, deserve(应得，值得), be worth值得），not bear(经不住) 后面接doing主动表被动。
The book is worth reading. 这本书值得一读。
The old building requires repairing. 这座古建筑需要修了。
These young seedlings will require/need looking after (=need to be looked after) carefully.这些幼苗将需要小心的照管。
