仁爱版英语九年级上册 Unit 3 Topic1 English is widely used throughout the world 导学案（无答案）

Unit 3 Topic1 SectionA 友情提示： 本课知识点：被动语态。 被动语态的构成：助动词be+及物动词的过去分词+（by+宾语） 其中by意为“被……；由……”，表动作的执行者。 如：The glass is broken by that boy.玻璃杯是那个男孩打破的。 be有人称、数和时态的变化，其肯定式、否定式、疑问式的变化规则与be作为连系动词时完全一样。 如：English is widely spoken around the world. （肯定式） English is not widely spoken around the world. （否定式） Is English widely spoken around the world? （疑问式） Yes, it is./No, it isn’t. 二、被动语态的用法： （1）在没有指明动作的执行者或者不知道动作执行者的情况下，可用被动语态。 如：This coat is made of cotton.这件大衣是棉制的。 （2）要强调动作的承受者而不是执行者时，用被动语态。 如：Her bike is stolen.她的自行车被偷了。 三、主、被动语态的转换： 主动语态：主语+及物谓语动词+宾语（+其它） 被动语态：主语+be+及物动词的过去分词+by+宾语（+其它） 把主动语态改为被动语态非常简单，可以遵循以下几个步骤： ??? 1. 先找出谓语动词；?????????????????????? ??? 2. 再找出谓语动词后的宾语； ??? 3. 把宾语用作被动语态中的主语；?主语用作被动语态中by的宾语。 ??? 4. 谓语动词变成“be+过去分词”，注意人称、时态和数的变化。 口诀：宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过去分词”来使用 注意： （1）主动、被动互转时，时态不变。 （2）主动句的主语是代词的主格形式，变成被动语态by的宾语时，要用宾格形式。如： People grow rice in the south. Rice is grown (by people) in the south. She takes care of the baby. The baby is taken care of (by her). 2、选择题 ( )1. —Do you often clean your classroom? —Yes.Our classroom ___ every day. clean B.cleans C.is cleaned ( )2.
