这是主动形式表被动的用法.
语法 :
主动形式表被动一般有两种情况:
1、动词need,want以及短语be worth等后常接动名词的主动形式,表被动.
例如:The room need cleaning.这屋子需要清扫.
2、某些表示主语质地,自身特征的动词,如write,wash,sell,read,clean等,常和副词well或easily连用,用主动表示被动含意.
如:
The pen writes well.这支笔写起来很流利.

这是主动形式表被动的用法。
该结构是:主语+系动词+形容词+及物动词(不可用被动式,不及物动词要加上介词,与主语之间有逻辑上的动宾关系)。
与之相似的结构是:动词+宾语+形容词+及物动词(不可用被动式,不及物动词要加上介词,与主语之间有逻辑上的动宾关系)。
用于此结构的常见形容词有:hard,defficult,easy,heavy,fit,good,comfortabl...
