there（ ）a singing competition next month.A.will have B.is going to have c.is going toD.is going to be就解释下a.c哪里错了吧.

who over there now A,who over there now A,singing B,sing C,is singing 请问,问号选什么? There are some girls ______under the tree over there.A.singing B.are singsing 单项选择：Who ________ over there now A.are singing B.sings C.is singing并讲讲选择的原因! 将划线单词的一个字母改变然后填入句子中There is a 【horse】 behind the （ ） in the picture.【Mike】 and Tom ( ) singing very much. There are many oranges ____the tree.A bird ___the tree is singing There is a boy in the room.He is singing合并为一句就这样 There are a few birds singing in the tree.对in the tree提问 Listen,there is a girl singing in the hall.这句话对吗? there is a boy singing in the park 为什么sing要ingthere is a boy singing in the park 为什么sing要ing A man singing love a singing contest是什么意思 singing a song是什么意思 who is singing over there?———— （ ）is my sister We are singing over there (划线提问) There are some birds singing( )the trees A few _____(girl）are singing under the tree We are singing a song.(改成一般疑问句）? there be 句型的现在完成时如：there is a bird singing singing可以理解为定语,但是可不可以理解为现在进行时? 根据THERE BE句型的倒装 =A bird is singing there,也很通啊 有人帮我解释一下嘛?
