1.   found difficult =v+ adj 可以嗎?是 v+adv吧
    可改為 found hard 或 found too difficult


3. I think ___ a pity that you didn't try harder

  S+Vi+ it + N +that + S+ V~~~~~

感謝大家的回答
我另外在知識+有提問，提供其他大大的解答給大家參考一下

看了大家的解答，第2題的答案似乎是B才對
其實這些題目是我在讀it當虛受詞這個單元的考題範例
下面是我在網路上找到的關於it當虛受詞的教學
http://www.nani.com.tw/nani/slearn/sle...3/Chapter13_1.htm
裡面我不了解的是it在什麼情況下可以不加
我想這就是關鍵所在
感謝哪位大大能為小弟解答一下
另外第3題的D是不是前面加that就可以選了，難道that不能省略麼?
像S+V+that+S+V 這種句型在什麼情況下that可以省略?
