一般现在时被动语态
初中英语语法——一般现在时的被动语态
现在,初中阶段淡化了语法的学习,但是语法还是很重要的,因为现在的语法考查一般都融入到文段中了,来的是综合性练习,这其实是要你有一定的语法基础的,所以不重视语法的学习你就没有了做题的基础。
下面就让我带你全面认识一般现在时的被动语态。
一、构成被动语态由“助动词be+过去分词”构成。
其人称、数和时态的变化都是通过助动词be 的不同形式表现出来的。
一般现在时的被动语态的谓语形式为'am/is/are+过去分词'。
示例(1)This jacket is made of cotton.这件短上衣是棉料的。
(2)Many trees are planted by us every year.我们每年种许多树。
典例二、句式结构肯定句:主语+am/is/are+过去分词(+by...).否定句:主语+am/is/are+not+过去分词(+by...).一般疑问句:Am/Is/Are+主语+过去分词(+by...)?示例(1)English is spoken by many people.许多人说英语。
(2)English is not spoken by many people.并不是很多人说英语。
(3)Is english spoken by many people.许多人说英语吗?典例三、用法(1)当动作的执行者不必或不易说出时,用被动语态。
示例:The flowers are watered every morning.这些花每天早上浇水。
(2)需要突出动作的承受者时,用被动语态。
动作的执行者由by引出且置于谓语动词之后,也可省略。
示例:The new teacher is liked by all the students.新老师被所有学生喜爱。
(3)表示“据说,据报道,人们相信”等,常用“It is+过去分词+that从句”句型。
示例:It is reported that a rainstorm is coming its way.据报道,一场暴风雨就要来了。
