have nothing to do with 和…无关
have a look at 看一看

2. hope 和 wish 的连系与区别
hope 一般侧重于表达有可能实现的愿望，故常译为“希望”。
wish 一般侧重于表达不大可能实现或根本不考虑是否可能实现的愿望，故常译为“但愿”。
相同点：
1） 表示“想”、“希望”时，均接不定式做宾语。如：
i hope （wish）to come tomorrow。我希望（但愿）明天能来。
2）均可与 for 连用。如：
let’s hope for the best。让我们尽量往好处想。
he wishes for a dictionary。他想得到一本词典。
不同点：
1) hope 和 wish均可接宾语从句。wish常用虚拟语气，表示一种无法实现的或不真实的愿望；而hope 用陈述语气，表示很有把握实现或得到。如：
i wish i were bird 。但愿我是一只鸟。
i hope she won’t come together 。我不希望她今晚来。
2）wish 后通常接“宾语+不定式（宾补）”，而hope 不行，如：
my parents wish （不用hope）me to grew up quickly 。我父母希望我快快长大。
3） wish 可接双宾语，表示“祝愿”，而hope 不能。如：
i wish （不用hope）you well and happy。我祝你健康幸福。
4）作简略回答时，hope 后可用替代词so 或not ，而wish 不能。如：

二、 既可接动名词也可接不定式作宾语但意义不同的动词
forget, remember, regret 后接不定式或动名词含义不同后接不定式或动名词含义不同
动词 forget, remember, regret 等接不定式时，表示非谓语动词的动作发生于谓语动词的动作之后；接动名词作宾语时，表示非谓语动词的动作发生于谓语动词的动作之前。
三、mean后接不定式或动名词含义不同
动词 mean 接不定式作宾语时，表示一种意图，意思是“打算做，想要做”；接动名词作宾语时，表示解释，意思是“意味着，意思是”。如：”i didn’t mean to bother you. 我本不想打扰你。what he said means going there by air. 他的话的意思是坐飞机去那儿。

need, require, want, 等表示“需要”的动词后另一动词作宾语时，该动词用不定式或动名词均可，但是其语态不同，即动名词用主动形式表示被动意义，而不定式则用被动形式表示被动意义。如：the flowers need watering every day. = the flowers need to be watered every day. 花儿需要每天浇水。注意：若 need, require, want后接动词为句子主语所发出的动作，则只能用不定式，不能用动名词。如：i need to water the flowers every day. 我需要每天给花浇水。
六、can’t help后接不定式或动名词含义不同
can’t help 后接不定式时，意思是“不能帮忙做某事”；接动名词作宾语时，意思是“禁不住做某事，情不自禁做某事”。如：i’m very busy now, so i can’t help (to) clean the room. 我现在很忙，因此不能帮助打扫房间。the girl couldn’t help crying when she saw her mother again. 当小女孩再次看到母亲时，她情不自禁地哭了起来。说明：以下两个动词后接不定式或动名词(不一定是用作宾语)意思也不同：go on to do sth (做完某事后)继续做另一事) (不定式作状语)go on doing 继续做一直在做的事 (动名词作状语)stop to do sth 停下正在做的事以便去做另一事 (不定式作状语)stop doing sth) 停做正在做的事 (动名词作宾语)
