fall apart

　　这个短语可以用来形容东西坏掉了，散架子了，to be in very bad condition so that parts are breaking off. 比如：

　　My car is falling apart.

　　还可以形容某件事存在太多问题，一团糟，没法继续了，to have so many problems that it is no longer possible to exist or function. 例如：

　　Their marriage finally fell apart.

　　The deal fell apart when we failed to agree on a price.

　　Come again?

　　说这个的目的，就是让对方再重复一遍刚才说的话，有时候是因为没听清，有时是因为带着某种情绪，比如气愤，不可思议等。例如：

　　‘She’s an entomologist.’ ‘Come again?’ ‘An entomologist—she studies insects.’

　　control freak

　　控制狂(a person who always wants to be in control of their own and others' lives, and to organize how things are done)

　　比如某些家长同志，时时刻刻都想知道自己孩子的行踪，甚至孩子的未来都已经一手策划好了的那种……
