关于“he后动词用什么形式”的问题,需根据具体语法场景判断:
一般现在时
主语为第三人称单数(如he)时,动词需加 -s 或 -es (如works, looks)。
动词ing形式
动词位于介词之后时,需用 ing 形式(如He is looking forward to...)。
系动词后
使用主格形式 he ,例如:
The meeting is scheduled for 3 PM.
The problem has been solved.
若需强调动作,可用宾格 him :
The letter was sent to him yesterday.
情态动词后
后接动词 原形 ,例如:
He can swim.
She would like a cup of coffee.
动词未变形 :
He blowyou(应为He blows you)
ing形式滥用 :
He is looking forward to climbing(正确)与He is looking forward to climb(错误)
非谓语动词 :
he可接that, who, whom等引导的定语从句,例如:
He is the one who helped me.
缩写与口语 :
在口语或非正式写作中,he可置于人名后,例如:
Tom likes playing football.
通过以上规则和场景分析,可灵活掌握he后动词的形式选择。
