陈述句的语调
Light meals are also good for health 是一个陈述句，但是说话人采用了升调，即疑问句语气，于是句子就变成了疑问句，表示说话人的疑问或吃惊的态度。不同的语调往往表示不同的意思，陈述句随着语调的不同，可以表达不同的情感。
1.陈述句在陈述事实时读降调，知：
I have been there before.(↖)
我去过那儿。
2.陈述句表疑问或惊讶时，用升调，如：
You have been there before.(↗)
你竟然去过那儿!
3.陈述句在表安慰、鼓励和友好时用升调，如：
—This is my son.
这是我儿子。
—Oh.he is so handsome.(↗)
喔，他真帅。
