　　4.You know that some people say more but do less ________ others do the opposite.

　　5.________ scores of times, but he still couldn't understand it.(Having explained, Having been explained, Though it was explained, It was explained)

　　答案：It was explained　解析：考查句子結(jié)構(gòu)。本句中的but是并列連詞，由此可知but前后都應(yīng)該是完整的句子。
