動詞不定式語法選擇題.關於主動表被動的、

題目：

動詞不定式語法選擇題.關於主動表被動的、
——Did the judge ask you many questions?
——Yes,and___.
a,they were difficult to be answered
b,to answer them was to be difficult
c,they were difficult to answer
d,they had difficulty in answering
答案是c,爲什麼不用a 問題不是被回答的嗎?如果是主動表被動,想問一下什麼時候用主動表被動.（最好說通俗點,不要說一大串專業的什麼）

解答：

很簡單 當不定式做補語時 當兩者聯繫很緊密時就可以不同被動語態
如 I have something to do 理解爲 do something
I have a lot clothes to wash 理解爲 wash clothes
I have a lot of homework to do 理解爲 do homework
凡是這樣的句子你都可以直接使用 to do 不用考慮 to be done也就是不定式的被動語態!
