英语情景会话
(以下B代表Bryan,C代表Cherry,W代表Waitress)
B: I like dining in this area. It is not necessary for you to give tips.
C: Yeah, but if you go to a fancy restaurant. they do expect tips.
B: Yes. Sometimes the tip is a lot of money.
C: That reminds me.I was in one of those theme restaurants. When I got the check.I found that the tip had already been added. I felt cheated.
B: In those restaurants which charge tips automatically, the waiters must share their tips with the owner. And their salary isn't very high, so the tips are an important part of their income.
C: Oh, you made me feel bad for them.
B: Don't be too bad. Just leave a tip. Waitress, can I have the bill?
W: Here it is, sir. Your bill totals 88 yuan.
B: Please add 15% to the total account. That's my tip for you.
W: Thank you very much, sir.
英语笔记
1.浊化现象，but 的/t/浊化为/d/，连读为/bʌdɪf/。
2.fancy restaurant 指“高级餐馆”。
3.省音现象。added 词尾的/d/在口语中几乎听不到。
4.加音现象。here it is 连读为/hɪərɪtɪz/加了辅助音/r/。
英语语音语调
英语的语调——降升调
对话中Bryan说 "Can ↗I↘ have the bill↗?" 表示用委婉的语气征求对方同意。在反意疑问句中，如果提问者对问题没有把握，希望对方回答时也用降升调，如：
It's going to↑ rain↘, isn't it↗?
要下雨了，不是吗?
陈述句在表示有言外之意时要用降升调，如：
A：Do you like the apartment?
你喜欢这套公寓吗?
B: It's↗ new↗.
挺新的。(就是小了点儿。)
