1.It doesn't even matter.
注意区分it doesn't matter与it is not bad;
it doesn't matter是不重要的意思,it is not bad是没有害处的意思;
例句:
It doesn't matter whether you have a pencil or not, as long as you have something to write with.
你有没有铅笔都没关系,只有有东西可以写字就行了。
It is not bad for old people to drink wine every once in a while.
老年人偶尔喝点酒没有什么大碍。
