Unit 8 It must belong to Carla.第一课时
基础知识
Ⅰ基本语言功能
情态动词表推测的用法
1. 按语气由强到弱排序如下:
must﹥will﹥would﹥ought to﹥should﹥can﹥could﹥may ﹥might
2. 陈述句例句:
(1) It must be Tom’s car.
这一定是汤姆的汽车。
据他自己的主观推断，现在格林先生现在应该在家里。但是他非常清楚自己的判断并不是十分靠得住。所以语气上留的余地就更大了。
( 4 ) They should be ready by 12 o’clock. Let’s go and visit them.
12点之前,他们应当是准备好了.我们去看看他们吧.
( 5 ) ① He can be here on time this evening.
今晚上可能他会按时到达吧。
3．否定的推测。
(1) 语气由非常肯定到最弱排序如下：
can’t ﹥couldn’t ﹥may not﹥ might not
(2) 例句
① The old man can’t be Tom’s grandpa because his grandpa has been dead for nearly two years。
那老头绝对不可能是汤姆的爷爷。因为他爷爷已经去世快两年了。
死了的人是绝对不可能在出现的。can’t表示说话语气上绝对地肯定。
② The old man couldn’t be Tom’s grandpa because his grandpa has been working abroard for nearly two years。
那老头不可能是汤姆的爷爷啊。他爷爷已经在海外工作快两年了呀。
③ He may not let you go unless you finish all of your work first.
除非先完成所有你的工作，否则的话，他有可能不让你走。
④He might not let you go unless you finish all of your work first.
除非先完成所有你的工作，否则的话，他也许会有不让你走的可能。
（2）Could you be a professional basketball player in the future?
将来你有没有可能性成为一名职业篮球队员啊？
较之于用can来提问，说话者对于对方能成为篮球队员的相信程度或者把握性更小。因此在询问的时候，给对方的回答留下了较大的余地。对方选择是或者不是的比例是一比一对等的。
Ⅱ基础词汇与短语
1.belong to sb. （所有权）属于某人。有人称,时态和数的变化形式。
(1) It belongs to me. 这个东西属于我所有。
(2) You belong to your parents. 你属于你的父母所有。
(3) This house belonged to my grandparents in the past.
之前这座房子属于我的祖父母所有。
2. attend a concert 参加音乐会。
(1)attend表示“参加”、“出席”，通常用作及物动词，其宾语通常是meeting, party, show, wedding, class, lecture, school, church等类似具有“活动”意义的名词。
eg. Did you attend the meeting yesterday?
你昨天去开会了吗?
(2) take part in指临时性参加群众性活动、会议、劳动、游行等，往往指参加者持有积极的态度，起一份作用。在这次活动结束后，所有参与者就各自散去。与join in可互换。
eg. Will you take part in the English evening with us this evening?
今晚上和我们一起参加英语晚会好吗？
（3）join 指的是永久性加入某个社团或者组织。
eg. join the Chicago Bulls 加入芝加哥公牛队。
join the army 参军
另外，join in 的意义和用法与take part in 可以互换。
3. anything valuable 任何有价值的东西。
修饰复合不定代词的形容词要放在的后面。
复合不定代词归类如下：
something anything nothing everything
somebody anybody nobody everybody
some one anyone no one everyone
somewhere anywhere nowhere everywhere
eg. somewhere relaxing and quiet 某个安静而放松的地方

重难点分析
1. It must belong to Carla
意思是，它一定属于卡拉所有。
该句子的核心语法点是情态动词表推测。
换一下情态动词：
It can belong to Carla 它可能属于卡拉所有。
It can’t belong to Carla它不可能属于卡拉所有。
It might not belong to Carla它可能不属于卡拉所有。
2．... so it might be still in the music hall.
句意是，既然如此，它有可能还在音乐厅里。
might 表不确定的主观推测。
原句去掉might的话，就成了：... so it is still in the music hall.
意思是，既然如此，它还在音乐厅里。句子就没有了主观推测的意味在内了。
3．So it can’t be stolen.
句意是，既然如此，他不可能被偷盗。
语法点是含有表推测的情态动词的被动语态。
将情态动词换掉，句意会发生如下的变化：
（1）So it was stolen. 既然如此，它被偷盗了。
（2）So it can be stolen. 既然如此，它极有可能被偷盗。
（3）So it may be stolen. 既然如此，它有被偷盗的可能性。
4．I think somebody must have picked it up.
我觉得肯定有人捡到了它。
该句子是主从复合句。宾语从句是含表推测的情态动词的现在完成时态的陈述句。
将情态动词must去掉，就成了，
I think somebody has picked it up.
我觉得已经有人捡到了它。
句意基本不变，只是去掉了说话者的主观推测成分。变成了纯客观性的表述。
含情态动词的现在完成时态基本用法如下：
（1） You must have used up all your money,haven’t you?
你肯定是已经花光了你所有的钱了，难道不是吗？
Are you sure what else they can have found out in this mountain?
在这座山里，他们可能已经找出了什么别的东西呢？对于这一点，你心里有数吗？
解析：
can have done sth.表示对过去所发生的事情的怀疑。往往用在疑问句之中。意思是“可能做过某事吗？”。
（2） John can’t have finished his homework. I noticed him being busy copying Mary’s just now.
约翰不可能已经做完了作业了呀。刚才我还注意到他忙忙活活地抄玛丽的作业呢。
解析：
can’t have done sth.表示对过去所发生的事情的否定性推测。意思是“不可能做过某事”。
（3） We may / might have all passed the English test,because our English teacher looks very delighted today.
我们的英语考试也许都及格了吧。我们英语老师今天看起来心情不错。

薄雾浓云愁永昼， 瑞脑消金兽。 佳节又重阳， 玉枕纱厨， 半夜凉初透。
东篱把酒黄昏后， 有暗香盈袖。 莫道不消魂， 帘卷西风， 人比黄花瘦。
