1.to be in a rut：是指对每天同样的工作或是墨守成规一成不变的习惯，感到单调乏味
(to be tired of routine job; nothing new or excited) (rut 这个字本意是惯例或老套）。
例如： he has not been promoted for 20 years; he must be in a rut.（他廿年未获升级，一定感到单调枯燥。)
after thirty years of the same job, he feels he is in a rut.（干了卅年同样的工作，他觉得枯燥乏味。） 所以要放弃单调枯燥的生活方式，就是 to get out of the rut.
例如： if you hate your old job, you need to get out of the rut.（假如你不喜欢你的老工作，你就要走出乏味的日子。)
2. to be (或 become) fed up with (someone 或 something)： 意思是对某人或某事感到讨厌或厌倦（to get tired of; to be disgusted or to get sick of);

we all became fed up with his long speech.（他的长篇演说我们都觉得讨厌。）
the husband has been fed up with his wife's nagging.（老公对老婆的唠叨感到厌烦。）
如果只用「to be fed up」也可以( kě yǐ)：
i will not wait for her; i am fed up. (我不想再等她了；我厌了。)
(动词时态是：feed, fed, fed) 可见这句俚语似乎有「被动味道」，如果用 feed，意思又不同了
例如： the mother will feed the baby with milk.（母亲喂婴儿牛奶。) (feed 是及物动词)
the cattle feed on grass (牛以草为生。)（feed 是不及物动词）
但是 the cattle were fed with the grass by the farmer.（农夫用草喂牛。）
可以( kě yǐ)说： i am fed up with him. (我讨厌他)
(但不能说：i feed up with him.）
3. to cut the cord: 意思是父母(fù mǔ)要让儿女离家过著独立自主的生活

it is very difficult for many chinese parents to cut the cord with their children.（许多(many)中国(China)父母很难让儿女完全(completely)独立自主。）(注：这里的 cord，是指 umbilical cord 即脐带。）
4. to start from square one: 意思是上次没有成功，必须回到起点从头做起
(something did not succeed in the first place, have to start over again） (这与 to be back to square one 意义相同);

the search committee for the new college president will have to start from square one.（选拔新校长委员会上次没有成功，现在又要从头做起。)
