(Grammar Focus-4c) What are the shirts made of ? 同学们，上一课学习的单词你们都掌握了吗？现在大家来检验一下，点击下面的音频开始听写吧！ 英语里有很多种时态，但却只有两种语态，即主动语态和被动语态，这两种语态的结构和用法有什么不同呢？这节课我们就一起来了解一下。Grammar Focus一般现在时的被动语态(一)概念：英语中动词有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。
(二)构成：被动语态由“助动词be＋及物动词的过去分词”构成，助动词be有人称、数和时态的变化。
(三)一般现在时的被动语态的构成：be(am，is， are)＋及物动词的过去分词。语法讲解魔法记忆一般现在时被动语态用法顺口溜：
一般现被动用be done，be有am，is和are；否定be后加not，疑问置be主语前。 考点 1【重点】由主语单复数确定be的形式。 典例To our surprise, the walls of the new bookstore________ books. (厦门)
A．are lined with B．is lined with
C．have lined with
【点拨】本题用主谓一致法解题。句意：让我们吃惊的是，新书店的墙上都排满了书。本句为被动语态结构，句子的主语是复数，be用are。
A考点 2【难点】强调动作的承受者，而不是执行者。 典例 A lot of trees ________around here every year and we can enjoy fresher air now. (六盘水)
A．plant B．is planted
C．were planted D．are planted 【点拨】本题用语法判定法解题。强调trees是plant这个动作的承受者，应用被动语态；主语trees为复数，且句中时间状语为every year，应用一般现在时。 D考点 3与一般现在时被动语态连用的时间状语有：every day，often，usually，always，seldom等。 eg：My room is cleaned every day by me.
我每天打扫我的房间。典例Some students in this school ________ abroad as exchange students every year. (自贡)
A．sent B．send C．are sent
【点拨】本题用语法判定法解题。主语students与谓语动词send之间是被动关系；根据句子时间状语“every year”可知时态应为一般现在时。
C考点 4一般现在时被动语态的疑问句与否定句。 疑问句：Is/Am/Are＋主语＋过去分词＋其他？
否定句：主语＋is/am/are＋not＋过去分词＋其他．
eg：Are these dishes washed by your mother?
这些碟子是你妈妈洗的吗？
The blackboard is not cleaned by Kate.
凯特没有擦黑板。典例________ this kind of question often asked in your class, Ann? (张家界)
A．Is
B．Does
C．HasA
【点拨】本题用语法判定法解题。句意：安，在你的班级，这种问题经常被问吗？本句为被动语态的一般疑问句形式，时态为一般现在时。
