騷客。眼迷離。

Which is right?

□ 1. All our staff cannot speak Chinese.

□ 2. None of our staff can speak Chinese.

     1. All our staff cannot speak Chinese.

○ 2. None of our staff can speak Chinese.

表示"全部都不..."時不可以all開頭後接否定動詞，而應以none of...起句後接肯定動詞。

Do not use a negative verb with "all". Use the negative subject at the beginning of the sentence " None of our staff", followed by a positive verb "can speck", e.g. "None of the orders was delivered yesterday". NOT: "All of the orders weren't delivered yesterday".
