1、“Its”是个中性的词汇，是物主代词。这个“Its”用来描述动物或没有生命的物体。“Its”和“It's”经常混在一起，是因为一些人错误地把“It's”当成所有格。不过，如果在"Jeanna's dog bit me."这样的句子中，名词后面的“'s”的确表示的是所有格。别把两者弄混了。下面举一些例子：
My oak tree loses its leaves in autumn.
My neighbor's cat never stays in its own yard.
That bottle of wine is cheap, but it has its pluses.
Google needs to update its privacy policy.
2、"It's"是 "it is" 或"it has"的缩写 。下面举一些例子：
It's (it is) a nice day
It's (it has) been a nice day.
it's (it is)
Thanks to the sewage spill, it's (it has) been a bad season for tourism at the lake.
1、查看例句。你会用"its" 还是 "it's" 来填空呢？ The museum needs to update __ online
2、问自己一些问题，有助于让你决定在空格中用 "its" 还是 "it's"。
“it is”或“it has”和句子搭配得体吗？ The museum needs to update it is online schedule for summer. 这个答案是错误的！
如果某物属于一个非生命体，可以用“its”指代吗？是的，因为“online schedule”就是属于“museum”的。正确的答案是：The museum needs to update its online schedule for summer.
3、再试一个例子，然后多问自己几个问题。 ___ hard to tell the difference between those shades of green."
"it is" 或 "it has" 放在句子中合适吗？ It is hard to tell the difference between those shades of green.
“it is”这个短语很完美地嵌入到了这个句子中，所以就不用再问自己问题了。正确答案是： It's hard to tell the difference between those shades of green.
