Each other

彼此用英语是each other。解释：each other 英[i:tʃ ˈʌðə(r] 美[itʃ ˈʌðər] v. （用作动词或介词的宾语） 互相，彼此; [例句]These two examples duplicate each other.这两个例子重了。They support each other in their work. 他们在工作中互相支持。The scientists have already experimented at each other's test sites. 科学家已经在彼此的实验场所进行了实验。They are reconciled with each other again.; They are on good terms again. 他们和好了。The ladies spent some time catching up on each other's health and families 女士们花了点时间叙旧，聊了聊彼此的健康和家庭状况。We are very familiar with each other. 我们相互之间很熟。
