This is Everyday Grammar. I'm Alice Bryant.
这里是《每日语法》节目。我是爱丽丝·布莱恩特。
On a recent program, we talked about the past participle.
在最近的一期节目中，我们谈到了过去分词。
Participles are word forms that serve special functions in sentences.
分词在句子中具有特殊的作用。
Past participles have three uses.
过去分词有三种用法。
Today, we focus on their use in passive sentences.
今天，我们重点讨论过去分词在被动句中的用法。
In most sentences in English, the subject performs the action of the verb.
在大多数英语句子中，主语执行动词的动作。
Take the example, Jenny stole my bag.
举个例子，珍妮偷了我的包。
The subject is Jenny and she is performing the act of stealing.
主语是珍妮，她正在执行偷窃行为。
But in passive sentences, the subject is acted upon or receives the action of the verb.
但在被动句中，主语是动词动作的接受者。
Take the example, My bag was stolen.
举个例子，我的包被偷了。
In English, the most basic passive sentence is formed with "be+past participle".
在英语中，最基本的被动句的结构是“be+过去分词”。
Let's examine the bag example more closely.
让我们更仔细地研究一下关于“包”的这个例子。
Here, the verb "be" appears in the past tense "was", and "stolen" is the past participle form of the verb "steal".
在这里，“be”动词以过去式“was”的形式出现，“stolen”是动词“steal”的过去分词形式。
Notice the end ending in "stolen".
注意“stolen”的词尾。
Past participles can end in "-n, -en or -ed" or have many other spellings. Most end in "-ed".
过去分词可以以“-n，-en或-ed”结尾或有许多其他拼写形式。大多数都以“-ed”结尾。
Listen for the structure "be + past participle" in this next statement:
注意听下面这句话中的结构“be+过去分词”：
The meat is cooked over an open fire.
肉被在明火上烤。
Here, the verb "be" is in the present tense "is".
在这里，“be”动词用的是一般现在时的形式“is”。
And "cooked" is the past participle of the verb "cook".
“cooked”是动词“cook”的过去分词。
You can learn more about past participles in our longer written program. And that's Everyday Grammar.
