We/You/They/ were working. 否定式: I/He/She was not working. 疑问式和简略回答: 4.过去进行时中的when和while when, while 区别： 由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时； 由while引导的时间状语从句，主句用一般过去时，从句应用过去进行时。 When the teacher came in, we were talking. 当此句改变主从句的位置时，则为： While we were talking, the teacher came in. 2)如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导。如： They were singing while we were dancing. Unit 6 An old man tried to move the mountains 1. unless引导条件状语从句 unless = if … not 除非；如果不 They will go tomorrow unless it rains. = They will go tomorrow if it doesn’t rains. as soon as引导时间状语从句。 ―……就 He will come and see you as soon as he can. 3. so.......that引导结果状语从句 句型1：主语+谓语+so+形容词/副词+that从句 The wind was so strong that we could hardly move forward. 句型2： so +形容词 + a/an + 单数名词 + that从句 It was so hot a day that they all went swimming. 句型3. so + many/ few + 复数名词 + that从句 He has so few friends that he often feels lonely. 句型4： so +much/ little + 不可数名词 + that 从句 I had so little money that I couldn’t buy a pen.

Lesson One is much easier than Lesson Two. Tom looks even younger than before. 1.当句中有than 时则用比较级。 eg: He is fatter than me. 2．当句子中的比较对象为两者时用比较级：“特殊疑问词+be+形容词比较级，A or B？” eg: Which is bigger，the earth or the moon？ 3. “比较级+and+比较级”表示“越来越……”。 eg.The flowers are more and more beautiful. 加more构成比较级的形容词则用more and more +形容词表示越来越… eg: English is more and more important. “the+比较级，the+比较级”表示“越……，越……”。 Eg.
