My life has change a lot in the past few years.
为什么用has,不能用have,
My life has change a lot in the past few years.
因为life ‘ 生活’ 是不可数名词,故谓语动词要用单数.

再问： 您能给我举几个用has的例子，再举几个用have的例子吗？非常感谢！
再答： 主语第三人称单数用has，其余人称用have，如 He has studied English for two years. The dog has four legs. Jim has a school bag. Lucy's father has a car . We have breakfast at 7 in the moring. Lily and Lucy have been good friends for 3 years. They have finishe their homework since two hours ago.
再问： 在过去进行时的句子中，比如I ___ (read)a newspaper while I ____ (wait)for the bus. 我在等车的时候看报纸。为什么用was reading呢？？
再答： while引导的从句，在这里是指两个动词在过去的某个时候同时进行。即我连等公共汽车边看报纸，动作已发生，故用过去时进行。即 I (was reading )a newspaper while I (was waiting )for the bus.
