解析：1.(There is)only an apple in the basket.

2.(There are)three boys in my family.
没有过去式标志词或短语 three boys说明是复数,故为There are
3.(There were)two books on the desk last night.
last night,昨天晚上,说明是过去式,又two books 是复数,∴填There were
4.(There was)a little water in the glass this morning.
water不可数,不可数名词谓语动词用单数,所以在is,are之间选单数is,又∵this morning是今天早上,已经看见过了,是过去式,所以There was
5.(There are)many maps of China on the wall.
没有过去式标志词或短语,maps是可数名词,前有many,后有s,说明是复数,故填There are
6.Long ago,(there was)a besutiful girl named Snow White.
a besutiful girl 中的 a说明是一个美丽的女孩,一个,为单数,且named 和.Long ago说明为过去式∴there was是正确答案
7.(There were)a lot of mice in the street last month.
mice 老鼠,是可数名词,a lot of 说明是大量的老鼠,可数名词复数,应该填are.
可是要注意.后屁股还有last month,上个月,说明为过去式,故正确答案为There were
8.(There are)any thll buidings in the past in China?
buidings后面跟了个小跟班“S”所以是复数,又没有标志性过去式短语或单词,
所以There are是正确答案!
