16.Some are ------ in the river and some are ------ games.A.

16.Some are ______ in the river and some are ______ games.A.swimming… playing B.swimming…plaiing C.swimming… I playing D.swimming…plaing 这道正确的应该是A C 项中的 I playing 明显不能填入句中,因为不符合语法规则,这里只能填一个动词的现在分词形式,C 项中多了一个“I” 19._____ he _____ on well with his friends this term A.Does…gets B.Does…get C.Is…getting D.Is…geting 这题选D 是正确的.因为this term还没结束,所以动作还在进行,应该用现在进行进,即is getting结构.
