1. alike兼有形容词和副词两个词性。而且alike做形容词时,是不能做前置定语的。如:The two office buildings are somewhat alike in appearance.这两座办公楼在外形上有点相似。The twins are so alike that I can't tell which is which.这对双胞胎一模一样, 我分辨不出谁是谁。2. 做副词时,similarly更多表示“相似地/类似地”,而alike准确的意思是“同样地”。当然similaryly也可以表示“同样”,此时等同于alike,但是这种用法较少使用。如:She treats all her students alike.她对她所有的学生都同样看待。The brothers dress similarly.兄弟俩穿得差不多。He was late and I similarly was delayed.他迟到了, 我同样也晚了。
