l can think of many cases where students obviously knew a lot of english words and expressions but couldn't write a good essay
特别是many cases where 这句
为什么这里case是抽象地点？？？？
many cases where 这是一个固定的词组 例如I can think of many cases where cultural differences really exist.我可以想出许多文化差异确实存在的事例。case是抽象的地点 后面WHERE引导具体的总的说来 你这句话的意思就是我可以想到许多学生显然知道许多英语单词和短语，但是却不能写一篇好文章。
