分析~下句子的结构和意思
l.personal computers are about to go through their biggest change since the rise of laptop.
答
笔记本电脑的兴起使个人电脑进入变革的时期
答
只能输入100各字，所以结构分析没法做了。就简单地提一两点吧。这是主系表状结构的句子，be about to do/be 有逻辑将要的意思，since引导的是是个条件或者是原因的状语词组
答
personal computers 是主语 go through 是谓语动词 their biggest change是宾语 since the rise of laptop是表示原因的状语 are about to 是将要的意思是修饰谓语的.
