2.What we used to think _____ impossible now does seem possi
2.B.was
句意:我们过去认为不可能的事现在好像可能了.
3.C.goes
( as well as 连接两个名词作主语时,谓动与前一个名词相一致,即与The father相一致,
又:every Sunday afternoon 暗示此句要用一般现在时,故选C)
4.C.keeps
(the number of +名词复数,作主语时,谓动用单三形式,故选C.)
5.A.is
(A poet and artist 一个诗人兼艺术家,指的是一个人,表示单数概念,故选A)
6.B.is
(Most of ...作主语时,谓动由of后的部分决定,此句中what has been said about the Smiths是一个从句,从句表示单数概念,因此谓动用is )
7.A.have; is (第一个Three years 表示“三年”,是复数,第二个Three years代表一个时间整体,是单数,因此选A)
8.D.is; are (估计是D答案的单词打错了,a应为are)
(第一个family 表示“家庭”这个整体,是单数,第二个family表示家庭成员,是复数,因此选A)
