课文详注 Further notes on the text
1. an article entitled‘Cigarette Smoking and Your Health’,一篇题为《吸烟与健康》的文章。
在英语中，文章名与书名中的每个单词的第一个字母均大写，不在开头位置的连词、冠词、小品词除外。entitle的含义为“给……题名/定名”，在这里是过去分词(短语)作定语。entitle常用于被动语态：
The writer hasn't entitled his new book yet.
那位作家还没给他的新书写/取名。
The book was entitled The Sun Also Rises.
那本书的书名为《太阳照样升起》。
2. I had all the usual symptoms of someone giving up smoking: a bad temper
and an enormous appetite. 我具备了戒烟者通常表现出来的所有症状：脾气暴躁和食欲旺盛。
a bad temper and an enormous appetite为symptoms的同位语。
giving up smoking可以看做是someone的定语，即someone who gives up smoking.
3. My friends Kept on offering me cigarettes and cigars.
我的朋友们不断地向我递香烟和雪茄。
keep on doing sth.表示“继续做某事”、“反复做某事”：
The child was crying loudly, but he kept on watching TV.
孩子在大声哭，但他却一直看电视。
He kept on phoning her.
他不断地给她打电话。
4.They made no effort to hide…他们毫不掩饰地……
make no effort表示“根本不作努力”。我们还可以说：
She wrote the letter with/without effort.
她费力地/毫不费力地写了那封信。
Georeg made every effort to get/at getting the job.
乔治竭尽全力想得到那份工作。
5. …it was more than I could bear. ……我再也忍不住了。more
than后面跟一个从句或一个形容词时可以表示“超出”(多用于口语)：
He was more than pleased with his new room.
他对自己的新房间极其满意。
This was more than I had expected.
这超出了我的预料。
6.Anyway,as Brian pointed out, it is the easiest thing in the world to give
up smoking.不管怎么说，正如布赖恩指出的那样，戒烟是世界上最容易的事情。
it为先行主语，代替后面的不定式短语 to give up…。 point out为固定短语，表示“指出”、“指明”：
Why didn't you point out his mistake to him at that time?
你那时候为什么不向他指出他的错误?
He pointed out that we still had to get a few other things.
他指出我们还需要/得再买一些其他东西。
