Of all the vast tides of migration that have swept through history, maybe none is more concentrated as the wave that brought 12 million immigrants onto American shores in little more than three decades. B. it may be that none is more concertrated as B的错误有"more..as..",有"it may be that none is" too wordy 但因为该题OG强调主句的2个比较句应为相同的过去式语态,因此B是不是还有一个"none is"的错误?应该改为"none was"? OG没有指出这个错误。我不知道这里的none is究竟是对还是错? -- by 会员 yoshimihoku (2010/5/28 17:44:41)
这里的none is是从句,主句的时态是may be,所以不能换成was |
