邀请、提醒、指令和建议

邀请可以用一般疑问句，句末往上扬。但邀请也可以像命令一样直接说：朋友之间不用 please，热情全靠语调，重音词上清楚地往下降。

An invitation can be in the form of a yes/no question. Listen to Sarah and Alan and repeat both parts.

情景：你在家开派对，Alan 在旁边小声提示你该说什么。照他的意思，用刚才那种直接、热情的祈使句回应（参考回答是我们给的示范，录音里不放）。

You are giving a party at your house. Alan's voice will whisper the ideas to you. The doorbell rings.

前面是用命令的口气请人做开心的事。真正下命令、让人做不太情愿的事，也是同样的降调，只是更干脆。跟读老师的话。

So far we have invited people to do this and that by ordering them to do something they enjoy. Sometimes orders are less enjoyable. Repeat the school-teacher's part in this scene.

牙医的「命令」不一样：他要病人放松、安心，所以句末用低升调，不是干脆的降调。跟读牙医的话。

A rather different kind of order is used by the dentist. Repeat his part.

家长和老师跟小孩说话也常用这种低升调，让孩子觉得安心。接着练警告：提醒别人小心时用先降后升的调子，意思其实是「不然会出事的」。

Parents and teachers talking to small children often use the same pattern. Imagine that Stephen is your little nephew. When he arrives at your house, tell him to wipe his shoes.

警告和劝告常常分不清，语调也一样：先降后升，听起来是「我是为你好」。David 突然想学爱斯基摩语，你来劝劝他。

Often it is hard to say what is a warning and what is a piece of advice. They can be difficult to distinguish. David has just decided he would like to learn an Eskimo language.

用问句提建议，语调和真正的问句一样：What about…? 是特殊疑问句，从高处往下降；Have you thought of…? 是一般疑问句，句末明显上扬。Let's 开头的建议则和祈使句一样用降调。Unless we… 是很委婉的另一种建议，用先降后升。

Suggestions in the form of questions take the same intonation as true questions. Listen and repeat Alan's part.

Roke 小姐给老板出主意，用的也是这种委婉的先降后升：Well, I could always… / you could always…（其实还可以……）。最高点落在 always 的 al 上。

The same intonation pattern we have just practised is used by Miss Roke in the suggestions she makes to Mr Watkins. Repeat her part.
