一道英语选择题,不懂啊
When I passed by that crossing, the scene of the terrible accident came to my mind clearly as if it had just happened yesterday.
A. what’s moreB. more or lessC. once moreD. no more
选C,没看懂
空档在clearly与as if之间...忘了打了

once more 的意思是 又一次 再次
what’s more 然而
more or less 或多或少的
no more 不再
比较意思就可以知道啦
