I can't do with loud music.=I can't tolerate loud music.我受不了喧闹的音乐。
④表示“与…有关”,用于have sth./anything/nothing to do with结构。
例如：
Her job has something to do with telephone.她的工作与电话有关。
deal with与do with用法辨析：
两者都有“处理；处置；对付”之意。区别在于：deal with中deal是不及物动词，本身不需要宾语，故常与how连用；do with中do为及物动词，须带宾语，故常和what连用。
例如：
You have to consider how to deal with/what to do with the material.
你得考虑用这材料做什么用。
What shall we do with the problem?/How shall we deal with the problem?
我们将如何处理这个问题？
20.It should also watch over my naughty niece, who comes to my house very often.（P24）
难句解读
它也应该看管好我那调皮的侄女，她常到我家闹腾。
watch over (sb./sth.)
是一个固定短语，意思是“看管；照料；监护；保护”（take care of）。
例如：
There must have been an angel watching over me that day.
那天，一定是有位天使在保护我。
The prince has two bodyguards watching over him every hour of the day.
王子一天二十四小时都有两位保镖保护着。
难点深究
watch构成的短语拓展：
watch out=be careful/look out/take care当心，留意; watch out for=look out for戒备，提防，密切注意; keep watch值班，看守，放哨; keep a close watch on sb./sth.密切注意，密切监视，严密看守。
例如：
Watch out! There's a car coming!
当心！汽车来了！
The customers are often reminded to watch out for thieves.
顾客经常被提醒要提防小偷。
The guards keep a close watch on the prisoners.
卫兵严密看守着囚犯。
