It was a pity that we met with a heavy rain and failed to catch the early train.
怎么改?为什么呢?
答：不知道.
More than one house were damage.
这个改错题 were改为was解释不了原因?
这个more than one..怎么理解啊?
答：house是单数,形式上是,就象Many a house,Every house作主语一样.你不要只想到中文的复数意思.met with 改为caught in？不必改为were caught inmet with有遭遇的意思。当然后者更好。
