From 1982 to 1987 sales of new small boats increased between five and ten percent annually. A) From 1982 to 1987 sales of new small boats increased between five and ten percent annually. B) Five to ten percent is the annual increase in sales of new small boats in the years 1982 to 1987. C)Sales of new small boats have increased annually five and ten percent in the years 1982 to 1987. D) Annually an increase of five to ten percent has occurred between 1982 and 1987 in the sales of new small boats. E) Occurring from 1982 to 1987 was an annual increase of five and ten percent in the sales of new small boats. 正确答案是A。给出的解释:“from 1982 to 1987标志着必须使用一般过去时。”个人认为from..to..标志的是一段时间,表示动作的持续可以用一般过去时也可以用现在完成时。BDE被排除是因为改变了句子重心,但是C和A比较起来,A优选是不是因为C中in the years 1982 to 1987表达累赘呢?还是five and ten percent用法有错?请教!!!!谢谢各位大人啦^^ |
