advise recommend虚拟语气
advise, suggest, propose, recommend等表示建议的宾语从句后要用虚拟语气。从句谓语由“should+动词原形”构成,其中的should在美国英语中通常可以省略。如:
He suggested that we should leave early. 他建议我们早点动身。
注:与动词insist相似,动词suggest后接宾语从句时,除可用虚拟语气外,也可用陈述语气,两者的区别也是:若谓语动词所表示的情况尚未成为事实,则用虚拟语气,此时suggest通常译为“建议”;若谓语动词所表示的情况为既成事实,则要用陈述语气,此时的suggest通常译为
“表明”、“认为”。比较并体会:
He suggested that we (should) stay for dinner. 他建议我们留下吃饭。
I suggested that you had a secret understanding with him. 我觉得你与他心照不宣。
