问题描述:
David,_____raised and educated in New York,lived and lectured in Africa most of his life.
A. who B. ifC.whileD.though
选哪个,并给出详解,为啥其他三个不行!谢谢
答
正确答案选D,though.
选A的话应该是从句,但是缺少be动词,正确的句子应该是"
David, who was raised and educated in New York."
选B的话,后面两个句子之间没有因果或者条件的关系,所以错
选C的话,后面两个句子应该是在同一时段内发生的,但是显然raised in NY和live in Africa不是一个时段内的.
两个句子各有一个动词,所以得处理成从句或者用连词.用though语法和语义上都说得通选C的话,后面两个句子应该是在同一时段内发生的-----哪两个句子啊?详细说一下好吗raised and educated in New York和lived and lectured in Africa most of his lifewhile在这句话中是“虽然”,不是“当”呀,为啥要同一时间while的这个意思不是这么用的,这个“虽然”表示的是对比,用来表示相反的情况。比如说I drink black coffee while he prefers it with cream.你这个句子里没有出现相反或者对比的意思,如果是说david是在NY长大的,但是Jean是在Africa长大的,那就可以用while,因为这是在对比两种不同的情况
