    A lot of debris-----------------at the site of explosion for quite a while.

    a:have been left b:has been left

    答案為(b)

    因為debris的意思為:殘骸、破瓦殘礫

    無法一一數出

    因此為不可數名詞(U)

    主詞為不可數名詞

    後面的動詞一定要用單數

    也就是has

    若為可數名詞則用have.

    是has been left

    因為debris (殘骸) 雖然字尾有"s" 是不可數名詞 而不可數名詞 永遠都是單數
