(to) do sth.：帮助某人做某事。 解析：to 可省略，小学阶段多省略 to，是最基础、最常用的搭配。 例句：I help my mom (to) clean the room every day.（我每天帮妈妈打扫房间。） 2. help sb. with sth.：在某件事上帮助某人。 解析：with 后接名词或名词短语，不能接动词，适用于具体的事情或科目。 例句：She helps me with my English.（她帮我补习英语。）/ He helps his dad with the housework.（他帮爸爸做家务。） 知识点3：help的常用搭配 （2）help 作名词的搭配 1. ask for help：寻求帮助。 例句：If you have a problem, you can ask your teacher for help.（如果你有问题，可以向老师寻求帮助。） 2. give sb. a hand / give a hand to sb.：帮某人一把（口语化，同义于 help sb.）。 例句：Can you give me a hand with this box？（你能帮我搬一下这个箱子吗？） 3. with the help of...：在……的帮助下。 解析：后接人或物，常用于句子开头或结尾，表原因。 例句：With the help of my friend, I finish my homework.（在朋友的帮助下，我完成了作业。） 单项选择 1.
