Feifei
但是我们可以说“talk about your holiday”或“speak about your holiday”。
在使用动词 tell 的时候，它后面紧跟的应该是“被告知信息的那一方”。来听两个例句。
Examples
I told you he would let you down.
我告诉过你他会让你失望的。
She told her mother she passed all her exams.
她告诉了她妈妈她通过了全部考试。
Feifei
但在使用动词 say 的时候，后面可以直接跟上要说的事情。比如：
Examples
I said he would let you down.
我告诉过你他会让你失望的。
She said to her mother she passed all her exams.
她告诉了她妈妈她通过了全部考试。
Feifei
在上面的例句中，“She said to her mother she passed all her exams”，“said” 后面跟着介词“to”。大家需要记住的是：you say something TO someone, but you tell someone something。
不过在日常生活中，说“She told her mother she passed all her exams”要比“She said to her mother she passed all her exams”更自然。请听下面这两句话，你觉得哪个说法是对的？
Examples
She said hello to her mother.
She told her mother hello.
Feifei
正确的句子应该是“She said hello to her mother”，因为与人打招呼是我们用行动“表达、表述”的事情，所以不能“tell 告诉”一个人我们在和他打招呼，而应该是“say hello”。
当然 say 和 tell 都可以用在间接引语的句子里，比如：“Martin said he was in a hurry”或“Martin told me he was in a hurry”；换成直接引语可以说：“Martin said: 'I’m in a hurry!'”或者“Martin told me: 'I’m in a hurry!'”
接着我们再来看看 say and tell 的一些其它常用方法。首先，动词 tell 可以表示“命令，吩咐”的意思。
Examples
The teacher told me to write an essay on birds.
老师让我写一篇关于鸟的文章。
