(1)第二种正确因为句子前是There are, 为复数且没有划线,因此提问应用复数
(2)与(1)是同样的问题, 这次have没划线,应选第二种
(3)应提问为:What are in the bowl? 与(1)(2)也是一样的道理,你只看be动词是单数还是复数即可
what are there in the bowl才对。如果(4 pears) are in the bowl.时才用前一种回答。
用have,注意在这种划线提问中,划线句是复数,那就该用复数。就像,若问(Marry has·····)那就用has。
how many years are there in the bowl?
who have just been to the people's park?
who are singing over there?
