Concerns about public health have led to the construction of three separate sewer systems between 1876 and 1904 to serve 你看看这个题。我选的B 错的原因是不是状语的位置不能随意改变? 感觉B 的between 1876 and 1904 有修饰systems的错误?

cutewen MM,这题是选B吗?A的错误确实是状语修饰错误。另外, between 1876 and 1904 是一个PERIOD,用完成时。 the construction of three separate sewer systems是完整的,最好不要拆。另外,不是时间状语放在哪个N后头就怀疑它修饰哪个N的,要考虑全局。 |
