麻烦稍微解释一下～谢谢～

Answer 1

1. The air is very hard to _______
   A.breath in.错 应该是 breathe in.

    B.be breathed. 错 这是动词不定式的反射用法 不能用被动形式

   C.be tolerated. 同B

   D.tolerate正确答案  其逻辑宾语 就是句子的主语
   2.Only when the war was over____return to his hometowns.
   A.have the soldiers时态错

    B.the soldiers 时态语序皆错

   C.the soldiers did 语序错

   D.did the soldiers正确答案  only 修饰状语置句首 主句要部分倒装  时态是一般过去时
   
   

2. 
   

Answer 2

1. 选B。 be hard to do sth 做某事困难。 breathe 动词： 呼吸

2. D。 only 放在句首，句子要用倒装语序。所以选D。

Answer 3

第一题选A 。。。因为是……it is hard to breathe the air in 所以呢，the air is hard to breathe in，只是宾语air提前了而已，主被动关系式是不变的，所以不用被动，依旧用主动表示被动
第二题选D。。。
