二． 重点单词和短语
1. I used to be afraid of the dark. 我过去怕黑。
(1)used to的用法
used to是固定结构，意为“过去常常，过去曾经（存在）”，表示过去某种习惯性、经常性的动作或过去存在的某种状态，暗含现在已不再发生或不存在之意。主语可以是各种人称，用于过去时态，其后跟动词原型。
E.g.:
①He used to be a very poor man.
他过去是一个很穷的人。
②She used to study in our school.
她曾在我们学校上学。
(2)used to的四大句型变化
句型变化 肯定句 Sb. used to... He used to play basketball after
school.他过去常常放学后打篮球。
否定句 Sb. didn’t use to... She didn’t use to have long hair.她过去不留长发。
一般疑问句 Did sb. use to...? Did you use to play the piano?你过去常常弹钢琴吗？
反义疑问句
附加疑问部分用did/didn’t He didn’t use to drink, did he?他过去不经常喝酒，对吗？
注意：在借助助动词did构成的疑问句或否定句中，used要变为use。
(3)辨析：used to do sth., be used to do sth., 与be used to doing sth.
used to do sth. 过去常常做某事 含有现在已不再发生或存在之意
be used to do/for
doing sth. 被用于做某事 是被动语态，动词不定式表示目的，可用于多种时态
be used to doing sth. 习惯于做某事 可用于现在、过去、将来等多种时态
E.g.：
①He used to go to sleep at 11 o’clock in the evening.
他过去常常在晚上11点钟睡觉。
②Wood is used to make houses./Wood is used for making houses.
木材被用来建房子。 ③He is used to going to sleep early.
他习惯于早睡。
2. He used to wear glasses, didn’t he? 他过去常常戴眼镜，不是吗？
反义疑问句
反义疑问句的基本结构是“肯定的陈述句+否定的附加疑问句”（即：前肯后否）或“否定的陈述句+肯定的附加疑问句”（即：前否后肯）。陈述句和附加问句在人称、数和时态上必须保持一致。
E.g.：
①Jim rushed to school this morning, didn’t he?
吉姆今早急急忙忙赶到了学校，不是吗？
②He isn’t a polite boy, is he?
他不是个有礼貌的孩子，是吗？
拓展：反义疑问句的回答：
(1) 回答反义疑问句和回答一般疑问句一样，如果事实是肯定的，用“Yes+肯定结构”；如果事实是否定的，则用“No+否定结构”。
E.g.：
The postcards are beautiful, aren’t they?
这些明信片很漂亮，是吗？
Yes, they are./No, they aren’t.
(2) 回答陈述部分为否定句的反义疑问句时，yes或no的汉语翻译与其本身的词意相反。
E.g.：
There isn’t a book store on the street, is there?
街上没有书店，是吗？
Yes, there is./No, there isn’t.
不，有。/是的，没有。

so和such两个单词意思相近，但是它们的词性和用法并不相同，使用时容易混淆。因此，在应用时要注意两者词性和搭配的区别。
①so如此地，这么，这样。常用搭配为“...+so+adj.+a/an+n.+...”
E.g.:
She is so lovely a girl. Her friends like her so much.
她是如此可爱的一个女孩子。她的朋友们很喜欢她。

“It has been +一段时间+since从句”的用法
此结构表示“自从...以来已经有一段时间了”。还可以表示为“It is +一段时间+since从句”。since后面的从句多用短暂性动词，通常用一般过去时。

=It is five years since I began to learn English.
