alike like 和likely有何区别？

词性不同，alike 副词做表语。like 介词，后面接名词。所以你的句子是不对的。不管是like（像）还是alike都不是动词，不能做谓语。正确的应为：
His son looks like his father.
His son and his father look alike.
至于likely找不到了,真是不好意思,抱歉~抱歉~~~

alike adj.相同的，相像的（仅作表语，可用much,very much修饰，不能用very修饰）adv.同样地，十分相像地Mother and I are much alike in many ways.They are dressed alike in blue.经典习语Great minds think alike.英雄所见略同。Like prep.像，相似adj.类似的，相似的（只作定语，是比较正式的用法，前面可用very修饰）He is very like his father.She responded in a like manner.Likely adj.有可能的，可用于句型：sb./sth.be likely to do sth. It is likely that…
