课文详注 Further notes on the text

I want to see sb., please 这一句式是表示想见某人时常用的句式之一。
2．have an appointment(with sb.)，（与某人）有约会。
I have an appointment with my dentist at 3 p.m. 我已约定下午3点去看牙医。

这里的it指“要见牙医”这件事。
4．Can you come at 10 a. m. on Monday, April 24th? 您在 4 月24日星期一上午10点钟来可以吗？
Can you come at…? 这一句式通常用来约定见面时间。注意英语中的时间次序一般是由小到大，与汉语正好相反。又如：on July 2nd, 1988（在1988年7月2日）, at seven on June 3rd, 1989 （在 1989年 6月 3日 7点）。 a. m. (=ante meridiem) 上午，有时写成A. M. 或AM；下午则是p. m. (=post meridiem)，有时写成 P. M. 或 PM。
5．I must see…我必须见……
比 I want to see…
语气上要更强些，表达说话人某种强烈的愿望或需求。
6．at the moment, 正在说话的这会儿，此时。
7．Can't you wait till this afternoon? 您就不能等到今天下午了吗？
这是情态助动词的否定疑问句形式，表示请求。
语法 Grammar in use
否定疑问句
否定疑问句可以表示说话者惊异的情绪、责难的口吻或赞叹；也可表示说话者的某种建议、邀请、请求或看法等。请看下列疑问句的简略否定式：
(be:) Aren't you a student? 难道你不是学生吗？
Isn't it hot here? 这里难道不热吗？
(can:) Can't you wait a moment? 你不能等一会儿吗？
(have:) Haven't I asked you? 难道我没问过你吗？
(do:) Don't you want to stay with us? 你难道不愿意与我们呆在一起吗？
(did:) Didn't you see him yesterday? 难道你昨天没看见他吗？
回答这种问题时用简略回答。如果答语是肯定的，就用 Yes；如果答语是否定的，就用No。不过，这种答语的汉语译法有特殊之处。
一般否定疑问句有完全式和简略式之分，它们的词序是不同的。
完全式：Is she not a nurse? 她不是一位护士吗？（简略式：Isn't she a nurse? 她不是一位护士吗？）
