What were you doing when the UFO arrived? （1）这是一个含有时间状语从句的主从复合句，主句为what were you doing，从句是由连词when引导的时间状语从句，说明主句动作发生的时间。 ex: The students were talking when the teacher came in. I was watching TV when the bell rang. When I got home, my mother was cooking. （2）arrive 是不及物动词，如果表示到达某地，则用arrive in /at …，相当于get to…或reach。需要注意的是，reach是及物动词，必须跟地点。get to 跟地点名词，如果是地点副词，则省略介词。如：get here/ home/there。 When did you ___________? When did you ___________ to school? They didn’t ___________ in China yesterday. We will ___________ there in two days. （A. arrive B. get C. reach） 2. While the girl was shopping, the alien got out. while 在此处用作连词，意为“正当……时”，引导一个时间状语从句，通常用过去进行时，而主句通常用一般过去时，也可用过去进行时。 ex: ①While I was sleeping, the telephone rang. ＝I was sleeping ___________ the telephone rang. ②Jim was watching the soccer game while Tom was reading. 3. When the UFO took off, the man was standing in front of the bank. take off 意为“起飞”，took是take的过去式。take off 还可表示“拿去，取消，脱掉（衣帽）”等。 ex: ①It’s hot in the room. You’d better take off your coat. （其对应词组为___________ ___________） ②They will take off the 5 am train. 4. The dog got out of his box and ran away. 此处的get out of … 意为“从……出来”，对应短语为get into… 也可表示上/下车（car, taxi），而上/下公共汽车、火车等则用get on /off…。 ①Mr. Black ___________ his car, then went into the shop.
