【合作探究】
探究一: 完成教材2d的任务
1.读2d对话，并回答下面问题。
1). Does Mr. Smith allowed students to take photos
. How does Sandy feel about the trip Why
3). What does Sandy think they should be allowed to do in the museum
4).How can we take photos in the art museum
2. 知识点：
Do you think we may be allowed to take photos if we don’t use a flash 你认为如果我们不使用闪光灯，我们可能被允许拍照吗？
【句型解析】此句是一个含有if 引导的条件状语从句的复合句。if 引导状语从句既可放于主句之前，也可以放在主句之后，当从句在主句前时，用逗号将其与主句隔开。 if引导的条件状语从句的时态一般遵循以下原则：如果主句的谓语含有情态动词can, may , must等，或主句是祈使句时，从句用一般现在时代替将来时；如果主句是一般将来时，从句也用一般现在时代替将来时。
【活学活用】1) 如果你需要钱，我能借你一些。
2）如果他来的话，我也会来。
I'll bring my camera anyway.反正我会把我的相机带来。
【词汇解读】
anyway为副词，在此意为“无论如何；反正”，在句中充当状语，用于转换话题、结束谈话或回到原话题上，相当于anyhow.
anyway还可表示“至少”，用于纠正说过的话。
【活学活用】1) 尽管他远不及完美，但她还是爱他。
2）他在这儿工作。至少我上次见他时是。
3)好了，我得走了，已经迟到了。
3.根据对话完成下面短文。
Sandy’s really excited about seeing the famous paintings ___ Picasso. Wu Lan’s glad Mr. Smith chose the art museum for their school trip. Sandy is going to bring a new camera to _________________. But taking photos _____________ in the museum. Wu Lan thinks they just wants _________ the paintings. So it _____________ to take photos if people don’t use a flash.
探究二 、语法精讲。
本单元我们主要学习含有情态动词的被动语态。
1.定义：含情态动词的被动语态用来说明某个被动性动作所反映出的感情和态度。初中阶段的常见情态动词有：can, may , need , must , should等。
谓语部分含有情态动词的被动语态的构成是：情态动词+be+过去分词。
例句：
Teenagers should be allowed to choose their own clothes.
应该允许青少年选择他们自己的服装。
Students should not be allowed to have part-time jobs. 不应该允许学生们做兼职工作。
Can these books be taken out of the reading room 可以把这些书带出阅览室吗？
When must the work be finished 这些工作必须什么时候完成？
句式：
转变方法
(一)将主动语态的宾语变成被动语态的主语。
(二)将含情态动词的主动句式变成被动句式，即： “情态动词+动词原形”变成“情态动词+be+过去分词”，然后再在其后加“by+主动句中的主语(人称代词用宾格)”。by短语也可省略。请看下列各句：
You should finish your homework first.
Your homework should be finished (by you) first.
You can take this magazine home.
This magazine can be taken home (by you).
4.句式变换
含情态动词的疑问句、否定句的变化均需借助于情态动词完成。
1. 一般疑问句：直接将被动语态的陈述句中的情态动词提前。
Must this task be finished at once 这项任务必须立即完成吗？
注意：含情态动词的被动语态的一般疑问句的回答，应保留原情态动词，但must表“必须”时，其否定回答应用needn’t；need表“必要”时，其肯定回答应用must。如：
--- Must my exercise book be handed in now
我的练习本必须现在上交吗？
--- Yes, it must. 是的，必须现在上交。
（No, it needn’t. 不，不必现在上交。）
2. 特殊疑问句 ：由特殊疑问词加上被动语态的一般疑问句构成。
When must this task be finished
这项任务必须在什么时候完成？
3. 否定句： 在情态动词后面加上not或never即可，但must表"必要"时否定式为needn't。
This task needn't be finished at once.
这项任务没必要立即完成。
4. 反意疑问句：借助情态动词构成附加疑问部分。如：
This bridge can be built next year, can't it
这座桥明年能建成，是吗？
