There are some___in these__.a.knifes...pencil-boxes b.knives...pencils-boxc.knives...pencil-box d.knives...pencils-boxes选择D对吗?
对的,knife的复数是knives.变fe为ve加s.
pencil-box复数为X后加ES

不对哈~~ 是 pencil-boxes

勉强选D。
there are后加复数形式，knife的复数为knives。these后加复数，用boxes，但应该是pencil-boxes。准确说没正确选项。

就是选择knife和pencil-box这两个单词的复数形式，所以要选C
后面这个单词的复数形式，体现在boxes上。属于特殊的复数变化，需要靠记忆。
