关于问路句型分析
Which is the way to North street Hospital? 去北大医院怎么走？
这是问路的一种说法，除此之外还可以说：
Where is North Street Hospital, please?
Can you tell me the way to North Street Hospital, please?
Can you tell me how I can get to North Street Hospital?
指点方向一般有以下几种表达方法：
Go along the road. Walk along the street.
Take the first turning on the right/left. Turn right/left at the second crossing.
It's next to … It's beside/behind … It's between … and …
考点指要
1．may表示可以(相当于to be allowed/permitted):
You may take this seat. (= You are allowed to take this seat.)你可以坐这个位子。
May I come in?我可以进来吗?
在回答这类问题时，人们通常避免用may来回答，而是用别的方式:
—May I sit here? ——我可以坐这儿吗?
—Yes, please. (或Certainly.) ——请坐吧。(当然可以。)
—Please don't. ——请不要坐在这儿。
—No, you mustn't. ——不，不行。
2．表示一件事可能会发生或某种情况可能存在(只能用于陈述句)
He may be busy today. 今天他可能很忙。
She may go to Beijing by air next month.她下个月可能乘飞机去北京。
A fool may give a wise man counsel.傻子也可能给聪明人出主意。(谚)
3．在表示目的或让步的状语从句中构成谓语：
Stand up so that you may see farther.大家站起来以便看得更远。
No matter what you may say, I will go ahead.不管你怎么说，我都要干下去。
4．可用于表示祝愿：
May that day come soon. 愿那一天早日到来。
May your dream come true. 愿你的梦想成真。
辨析cross, crossing和across
A. cross与across都可译作“横穿/越过”，但词性不同。cross是动词，across是介词，cross sth. = go across sth.,
Go across the bridge. 横穿过那座桥。
B. go across 横穿过，区别于 go along沿着，一直走。如：
