崩塌的英语

第一个我认为应该选B break it up into parts,把句子分成很多部分第2个。。break down没有问题，，表示谈判的失败。。break down有摧毁失败的意思。。break up 也有摧毁的意思。分离，分解。。但是程度上break down 更强

fall apart或者 collapse~

v. 下来，下落vi. （价格、温度、比率等）下降；着陆；崩塌；决定并宣布（支持或反对）

常见表达有这样几种： 1.His spirit seemed broken. 看来他的精神崩溃了。 2.He almost broke down. 他精神几乎崩溃。 3. He is verging on a breakdown. 他正濒临精神崩溃 。 4.I was near the point of breakdown. 我已经到了精神崩溃的边缘了 5.Family problems made him crack up. 家庭问题弄得他精神崩溃了。 6.The loss of his business just curled him up 生意亏损使他精神崩溃了。 7.After the car accident, he seem to go to pieces. 撞车事故后, 他好像精神崩溃了。 8.He went off the deep end after his wife left him 太太弃他而去之后,他就精神崩溃了

Break up 有分成碎片的意思，而break down多指崩塌，倒塌，有引申的含义，比如一个政权或者国家的消亡。另外可以参照下面的cut down和cut up的用法去理解：The wood cutter is cutting down the big tree. 伐木工人正在砍倒那棵大树。The wood cutter is cutting up the fallen tree. 伐木工人正在把倒下的大树砍碎。
