Question

i was lucky

I was lucky (in that) I was able to find a good baby—sitter.为什么用in that

Answer 1

lucky in that -----的原始意思是“在- - - 方面”幸运.that的存在意味著後面是一个从句,而不是一个短语.in that-------现在作为“连接词”使用,解释为“因为”.你可以把in that当作because来使用.
I was lucky (in that==) BECAUSE I was able to find a good baby-sitter.
