在陈述句中，当主语是单数第三人称（he、she、it）时，句子的谓语是“有”时，用has；当主语是其他人称（I、you、we、they）时，句子的谓语是“有”时，用have。
例句：
I \ You have an apple .
We\They have some apples .
He\She has a pen .
但是，在疑问句中，当主语是就单数第三人称提问或否定句时用助动词does 和does not (doesn't)，然后把has 变成have 如果不是第三人称,助动词就是do ,否定式do not (don't).特殊疑问句回答照样,该是has 还是has 该是have 还是have 但是当一般疑问句 以do或does开头的时候,只能回答 do dont 或者 does doesn't
例句：
Do you have a book ? yes ,I do /No , I don't
What does a cat have ? the cat has a ,,,,,,,
He doesnt have any coffee.
have本身也可以作为助动词，(作为完成时里的助动词)本身无词义，和do 一样,has 就相当于does 在单三情况下用, 主要用于构成各种时态、语态、语气以及否定和疑问结构。（那此时的have还是has就要看具体的人称而定）完成时态是have/had + done (过去分词的形式)
I have finished my work, she has finished her work
have you finished your work? has she finished her work? 在一般疑问句里回答直接用have/has
yes,i have/ No , i haven't Yes, she has/ No, she hasn't(因为这里have/has是助动词)
这类的题目主要是看主语的主体部分，解决这类问题最好的办法是找主体，比如第一个"s该地区三分之一",显然主体是area,不可计量，自然选择"is",而后面主语的主体是"trees"是复数名词了，自然使用"have"了。
其实这类题目很简单的，也不用管我这上面的解答，其实记住一样就行，那就是明白面前的几个单词说的是啥，就能判断单复数了。比如前面说的是地区，单；然后后面说的是trees,复数。这样做题就会很简单，而且很高效。
1%+【sl】n + is
1%+【pl】n + are
1%+【u】n + is
第二：如果把第一中的1%全改成20%那么后面谓语还是不变
第三：20%=1/5后面的谓语is/are不变
谓语是看主语的可数与不可数,与具体比例没有关系
参考:网页链接
这是主谓一致上的问题，表示数字要看of后面的词。trees是复数
