题目内容
12.Thomas Edison had more than two ______ inventions during his lifetime.( )| A. | thousand | B. | thousands | C. | thousand of | D. | thousands of |
分析 爱迪生一生当中有两千多项发明.
解答 答案:A.
当hundred、thousand、million前面有具体数字表示准确的数目时,后面不能加-s,也不能和of连用;当hundred,thousand等前面没有具体数词时,需要与of连用,表示不具体、不准确的数目时,词尾须加-s.本题设空处前面有具体数词two,所以用thousand,故选A.
点评 本题考查数词的用法,在平时的学习中注意积累与运用,达到熟练掌握的目的.
