A. banana; tomato B. bananas; tomato C. bananas; tomatoes D. banana; tomatoes 【答案】 C 【解析】【分析】句意:我想要一些香蕉和西红柿。banana和tomato都是可数名词,some后接复数形式,因此是bananas和tomatoes,故选C。 【点评】此题考查名词复数。注意some后跟可数名词复数。 3.(.山东临沂)I live near the station, It‘s only about five ________ walk. A. minute’s B. minute C. minutes’ D. minutes 【答案】 C 【解析】【分析】句意:我住在车站附近。只有大约步行五分钟的路程。英语中基数词+时间词的所有格+交通方式,可以表示用这种交通方式需要多长时间。时间词根据基数词不同而进行单复数变化。本题中minute应该用复数形式,后面加s;故变为所有格时后面只加'即可。选C。 4.(?苏州)Steve Jobs was full of — always coming up with new ideas which led to great changes in society. A. instruction B. invitation C. introduction D. invention 【答案】 D 【解析】【分析】考查名词辨析。句意:史蒂夫·乔布斯充满了发明-总是提出新的想法,这导致了社会的巨大变化。instruction指令;invitation邀请;introduction介绍,说明;invention发明。结合语境,所以选D。 5.—I'm looking forward to the final of the 2018 World Cup. —Me too.
