Tom 一边唱歌一边跳舞。典例：1. When I came back yesterday evening, my brother _ his homework. A. is doing B. has done C. was doing点拨：根据句意：当我到家时我弟弟正在做作业，用过去进行时。答案：C 2.

He doesnt pay attention to where hes going or what hes doing.pay attention to意为“对注意；留心”。其中to是介词，to后接名词，代词或动名词。名词attention前可以有more, little, careful, close, no, some等形容词修饰，同义短语 “look out for”。 eg: He didnt pay attention to the teacher.他没有专心听老师讲课。中考链接：（2020荆州）After that, her teacher (更多地关注) her. (pay) 答案：paid more attention to3. The accident happened to a girl called “Lucky”. 事故发生在一个叫“幸运”的女孩身上。happen 和 take place 的区别1）happen常指预想不到或出乎意料的事件的发生。具有偶然性。take place 指实现计划好或预想到的事情的发生。具有必要性。如：The accident happened last year .The wedding(婚礼) took place yesterday .2）happen的三种用法：（1）“sth.+happened+地点/时间”意为：“某地/某时发生了某事”如：An accident happened in that street .(2) “sth.+happened to + sb.”意为“某人发生了某事”（常指不好的事发生在某人身上）如：A traffic accident happened to him yesterday .(3) “sb happened to do sth.”意为“某人碰巧做某事”如：I happened to meet her in the street .典例：Yesterday，an accident _(发生) in that road. 答案: happened (表示事情突然发生)当堂达标：一、单项选择。( )1.
