构成被动语态的替代方法
您可以用动词 to get 或 to have 取代 Be 动词，构成具有被动语意丶但并非被动语态的句子。这些句型构造通常描述的状况有：希望某人为自己做某事，或雇某人来为自己做某事等。主词是主动的，但他做的只有「令」某人做某事。句中主要动词要求做某动作的对象并不会被指名。当句子有被动的意味时，第二人并不明确。我们更关注动作的结果，而不是关注做动作的人。
举例
- I must get my hair cut.
- I must have my hair cut.
- When are you going to get that window mended?
- We're having the house painted.
这类构句指的可能是动作的完成，特别句中有时间用语的时候。
举例
- We'll get the work done as soon as possible.
- I'll get those letters typed before lunchtime.
- She said she'd have my lunch delivered by noon.
- You should have your roof repaired before next winter.
如果动词指的是不必要丶不愿发生的事，就有被动句的意味。
举例
- Jim had his car stolen last night.
- Jim's car was stolen.
- They had their roof blown off in the storm.
- Their roof was blown off in the storm.
"to need" 用于被动构句
在主动句中，也可以用动词 to need + 动名词来让句子有被动的意味。对我们来说，这些句子的重点在于「承受」某动作的人或物，而非「执行」动作的人。
举例
- The ceiling needs painting.
- The ceiling needs to be painted.
- My hair needs cutting.
- My hair needs to be cut.
- That faucet needs fixing.
- That faucet needs to be fixed.
