1 There are

1 There are ____books in the bag 2 There ____ an apple and ten bananas in the basket
1 A not B no C not a D any not
2 A are B has C is D have
1 There is a young girl ____ in the room
A singing B is singing C sing D sings
2 There _______ bread in the box
A isn't some B am not C aren't some D isn't any

B
C
there are no books 相当于 there are not any books
第二题中there be 结构遵循就近原则,an apple是单数,用is
there is a young girl singing in the room 现在分词作后置定语,这种分词作定语的我们要考虑和中心词的主被动关系,这里的sing是the girl主动进行的动作,所以用ing形式
最后一题中,因为是否定句,所以不用some,而there be 要遵循就近原则,后面的名词是bread,所以be动词只能用is
再问： 所以最后两题选A和D对吗
再答： 对的，完全正确！
