Lunch is usually eaten at about 1 pm.

Knives and forks are used for most Western food.

【自学查疑】

被动语态基本用法:

    当句子的主语是动作的执行者时，谓语的形式是主动语态。当句子的主语是动作的承受者时，谓语要用被动语态。被动语态由“助动词be+过去分词”构成，时态通过be表现出来。

结构: be + V-p.p.

一般现在时的被动语态: am / are / is +动词的过去分词

一般过去时的被动语态:

was / were +动词的过去分词

一般将来时的被动语态:

will / be(am/is/are) going to +动词的过去分词

【合作解疑】动语态的运用:

（1） 不知道谁是动作的执行者或没  有必要知道谁是动作的执行者时。

The house is quite old. It was built in 1950. 这座房子太旧了，它是1950年建的。
2） 需要强调动作的对象即宾语时。

Calculator can't be used in the math exam.  计算器不能用于数学考试。

3)有时为了礼貌等原因不愿说出行为者,这时也常用被动语态。

The construction of the new lab must be completed by the end of next month.

    新实验室必须在下个月底前完工。

You are requested to give a performance.请你给我们表演一个节目。

【归纳总结】：

主动句变为被动句所遵循的4个步骤：

1. 把原主动句中的宾语变为被动句的主语。

2. 把动词变为被动形式即be+过去分词，并注意其人称和数随主语的变化，而动词的时态则保持不变。

3. 原主动句的主语如需要则放在by后面以它        的宾格形式出现（注代词的宾格），如不需要则可省略。. 其它的成分（定语、状语）不变
