On seeing me, he waved to me.  7． D 原句中unles----if…not / except on the condition thatwhen=if except可以和名词/名词性从句进行搭配，也可以是when / if 引导的从句形式。 8． D must be 只是对客观现实的推测，时态不一致 情态动词表达推测的语意概念时，对于过去事实推测一定要用于情态动词have以及过去分词形式进行搭配。 9 C no more than = only within = not more than 10 B .in a corner 表示处于困境、尴尬的境地 in a trap 表示落于陷阱中 at an angle 表示弯曲的、不直的 11 fishes for pleasure 钓鱼为了游玩 12、A .on his own = alone C选项是秘密的，D选项是不为总人所知的。不符合语义。 Lesson2 thirteen equals one Learning objectives: 1、However的用法； 2、掌握used 的基本用法； 3、了解强调句型的结构； 4、介词in 用法总结。 Lesson 2 Thirteen equals one vicar. Youve probably woken up everyone in the village as well. Still, Im glad the bell is working again. Thats the trouble, vicar, answered Bill. Its working all right, but Im afraid that at one oclock it will strike thirteen times and theres nothing I can do about it. Well get used to that, Bill, said the vicar. Thirteen is not as good as one, but its better than nothing. Now lets go downstairs and have a cup of tea. However的用法 however 用于口语，主要用于句首，作文中，最好用在句中、句尾，翻译时放在句首，要用逗号分隔开来 He said that it was so, he was mistake, however. or: He said that it was so, however, he was mistake. I know his story, however, I wouldn’t like to tell you. however 可用nevertheless nonetheless 替换 2、掌握used 的基本用法 “Uesd to +动词不定式”这一结构只有过去式，指过去的习惯和状态。如果我们说某人used to do sth。意思是不久以前他习惯于做某事，但现在已经不做了。 1.在疑问句里可把used放在主语前面，作用相当于助动词。如： used to come by train? 2、掌握used 的基本用法 在否定句里有以下几种形式： he used not to come by train?（主要用在文字里） he usedn’t to come by train? he didn’t use to come by train? (以上三例主要用在谈话里） 2、掌握used 的基本用法 注意: 1. be used to do sth (=be employed to do sth
