Prep里面解释是...times+more+adj+than, ...time as + adj + than都正确

先汗一个，不说more than那个，就那as than说吧，明显是错的嘛

看了白勇里的知识点：

有道理，你比我细心啊！这都看出来了！

还有，那A be n times more adj than B会不会产生歧义，A是B的n倍呢，还是A是B的n+1倍，我忘了在哪有这个说法，说times more adj than 模糊不清，不是ETS的偏好

本题用了many times more adj than另当别论了，因为many表示很多，非具体值，也就不会有什么歧义了。
