每课一句：新概念英语第1册第73课
【往期回顾】
接下来，我们就来看看第73课的“每课一句”。
一、课文原文
Lesson 73 The way to King Street
Last week Mrs. Mills went to London. She does not know London very well, and she lost her way.
Suddenly, she saw a man near a bus stop. “I can ask him the way.” she said to herself.
“Excuse me,” she said. “Can you tell me the way to King Street please?”
The man smiled pleasantly. He did not understand English! He spoke German. He was a tourist.
Then he put his hand into his pocket, and took out a phrasebook.
He opened the book and found a phrase. He read the phrase slowly. “I am sorry,” he said. “I do not speak English.”

二、每课一句
Last week Mrs. Mills went to London.
本课继续学习一般过去时，但侧重的是动词过去式的不规则变化。
本课里出现的不规则动词有：
go - went
lose - lost
see - saw
say - said
do - did
understand - understood
speak - spoke
be - was/were
put - put
take - took
find - found
read - read
【注意】
需要注意的是，很多动词的过去式虽然是不规则的，但其中也有一些其实是有一定规律的。比如以-eep结尾的动词，其过去式大多是把-eep改为-ept，如：
sleep - slept
sweep - swept
creep - crept
再比如，很多以-end结尾的动词，其过去式大多是把-end改为-ent，如：
send - sent
spend - spent
bend - bent
当然，这些规则的掌握是建立在掌握了足够多的不规则动词之后才能发现的，所以还是需要注意平常多积累不规则动词的过去式变化。
三、更多拓展
Suddenly, she saw a man near a bus stop.
注意句中的suddenly，这是本课出现的有关形容词转化为副词的构词法知识。
课文中出现了三个这样的词语，即：
suddenly
pleasantly
slowly
从构词方式来看，这三个词都是由“形容词+后缀-ly”来构成副词的。即：
sudden+ly
pleasant+ly
slow+ly
所以，对于这类副词，只需要知道其形容词的含义即可。
当然，需要注意的是，后缀-ly加在形容词后是构成副词的，但它也可以加在名词之后，只是此时它所构成的不是副词，而是形容词。比如：
friendly: friend+ly
lovely: love+ly
weekly: week+ly
