20. GWD26-Q20 In 1981 children in the United States spent an average of slightly less than two and a half hours a week doing household chores; by 1997 they had spent nearly six hours a week.
A. chores; by 1997 they had spent nearly six hours a week B. chores; by 1997 that figure had grown to nearly six hours a week GWD答案是B 我选的A。因为我觉得用分号隔开的是两个完整的句子,这两个选项都满足啊,从结构上来看A的结构与原句的前半段更接近啊,貌似也没有什么语法错误,搞不明白,求大NN指教…… |
