表示“帮助某人做某事”,强调协助他人完成某个具体动作或任务。
该短语的本质是“help + 宾语 + 省略to的不定式”(不定式作宾语补足语),以下是关键用法要点:
在主动句中,"help" 后面接宾语(sb.)后,不定式的to可以省略(口语中几乎必省),直接用动词原形:
I help my mom cook dinner every weekend.(我每周帮妈妈做晚饭。)
Could you help me carry this heavy bag?(你能帮我提这个重袋子吗?)
如果句子变为被动(即“某人被帮助做某事”),省略的to要补回来,结构为 "sb. be helped to do sth.":
The little boy was helped to cross the street by a kind lady.(小男孩被一位好心女士帮忙过马路。)
I was helped to fix my bike by my brother.(我哥哥帮我修好了自行车。)
不仅“人”能作主语(表示“某人帮助他人”),物也能作主语(表示“某物/某事对人有帮助”):
This dictionary helps me understand English words better.(这本字典帮我更好地理解英语单词。)
Exercise helps people stay healthy.(运动帮助人们保持健康。)
若要表达“帮助某人做某事”,还可以用 "help sb. with sth."(后面接名词/代词,而非动词),两者可互换:
She helps me learn English. = She helps me with my English.(她帮我学英语。)
Can you help me clean the room? = Can you help me with the room cleaning?(你能帮我打扫房间吗?)
不能说 "help sb. doing sth."!(×)
错误例句:He helps me learning math.(他帮我学数学。)
正确表达:He helps me learn math. / He helps me with my math.(√)
"help sb. do sth." 是高频日常短语,核心是“协助他人完成动作”,关键要记住:
主动句省to,被动句补to;
人/物都能作主语;
可与 "help sb. with sth." 互换。
通过例句加深记忆:
My dad helps me repair my computer.(爸爸帮我修电脑。)
The volunteer helped the old man carry his groceries.(志愿者帮老人提杂货。)
I was helped to prepare for the exam by my teacher.(老师帮我准备考试。)
