It doesn’t work. = There is something wrong with it.
I pressed the “ON” button but nothing happened.我按了“开”的按钮，但没反应。
happen --- 发生(主语必须是事) 如：
An accident happened last night. 昨天晚上发生了一起车祸。
press v. 按，压 如：
Don’t press it. 别按它。
Well, are you sure you plugged it in 那么，你确信接通电源了吗？
plug in 是一个“动词+介词”组成的动词短语，意为“接通（电源），把插头插进插座”。这种动介结构的短语的共同点是：接名词时，名词用于中间和后面均可；接代词时，只能把代词放在中间。如：
Please plug the TV in. = Please plug in the TV.请把电视接通电源。
请把它接通电源。Please plug it in. (√ )
Please plug in it. ( ×)
