10.She can't tell the sheep from the goats.
她分不清好賴人。
在英語中,the sheep and the goats常用來意指好人和壞人,因此not tell the sheep from the goats 也就有了分不清好人和壞人的意思了。
如:She can't tell the sheep from the goats. I once helped her a lot, but in the end she said she didn't need my help at all.
她分不清好賴人。我曾經幫過她大忙,但是最后她竟然說她根本不需要我的幫忙。
