The new aircraft will be subjected to a test of temperatures of -65℃ and 120℃.

请教老师本句的be subjected to是不是相当于及物动词短语，做谓语呢？

【答】为了从根本上弄清楚这个问题，我先给你讲一下be subjected to结构的来历及其演变。

1. 首先要知道，subjected 是动词subject的过去分词。

2. 把be subjected to理解为被动语态结构，或者形容词短语，都可以。

3. 严格讲，把be subjected to 看作及物动词短语做谓语，不妥。应该这样说：a test是介词to的宾语。

4. subject是及物动词，意为“使服从于；使隶属于；使屈从于；使受制约；使接受”。后面必须接宾语。结构为：subject + 宾语 + to, 例如：

You should subject yourself to my command. 你必须服从我的命令。

→You should be subjected to my command. 你必须服从我的命令。

5. The new aircraft will be subjected to a test of temperatures of -65℃ and 120℃.

意思是：新飞机将经受-65和120摄氏度的温度测试。

这句话，因为主语表示“事物”，其主动式的主语一般不是事物本身，而是“人”。变成语态可能是：

The engineers will subject the new aircraft to a test of temperatures of -65℃ and 120℃.

▲关于这类动词的用法，再举一些类似的例句：

他很快就习惯了这种新的生活方式。

She was adapted to the new climate quickly.

她很快就适应了这种新气候。
