英语情景会话
(以P代表Peter，A代表Attendant)
A: Can I help you?
P: I want to check my luggage.
P: Five.
A: Place them on the scales please. I'm sorry, sir. Your baggage is 4 kilos overweight. You have to pay extra money for it.
P: Oh, what is the limit?
A: The limit is 20 kilos per person and there's surcharge of eight dollars per kilogram on overweight baggage.
P: Can I take these two with me?
A: You're only allowed one piece of carry-on luggage. Sorry, but that's our policy. I think this one could go on as carry-on luggage if you like.
P: Oh, yes. Thank you. This is fragile. I need to carry it on.
A: So now you should pay 16 dollars.
P: Okay.
A: And please make sure there are no sharp objects in your hand luggage. This is your luggage check, which you must show when you disembarks at your destination. Enjoy your trip.
P: Thank you.
英语笔记
1.此处省略了主语和谓语，完整句子为How many pieces do you have?
2.What is the limit?意为“上限是多少?”。
3.allowed 为规则动词allow 的过去式，allow为元音/aʊ/结尾，所以allowed 读作/ə'ləʊd/。
4.carry it on 连读为/'kærɪtɒn/。
英语语音语调
规则动词过去式词尾-ed的发音
你听到的allowed读作/ə'ləʊd/。这是遵循了规则动词过去式发音的基本规则。具体情况如下：
1.以/t/或/d/结尾的动词，其过去式末尾的-ed发音为额外音节/ɪd/，如：
wait→waited/weɪtɪd/
等待
2.以浊辅音结尾的动词，其过去式末尾的-ed发音为浊辅音/d/，如：
close→closed /kləʊzd/
3.以清辅音结尾的动词，其过去式末尾的-ed发音为清辅音/t/，如：
work→worked /wɜ:kt/
工作
注：1.如果动词过去式后面的单词以元音开始，那么词尾的-ed与后面的单词连读，如：
stressed out /stres taʊt/
过度紧张
cooked it /kʊktɪt/
烹饪
2.如果动词过去式后面的单词首音与该动词的词尾发音相同或相似，则出现不完全爆破，如：
planned to /plæn(d)tʊ/
打算做某事
listened to /ˈlɪsn(d)tʊ/
听
