Language pints
1.I attended a cncert yesterday s it might still be in the music hall.我昨天参加了一场音乐会，所以它有可能还在音乐厅里。
【词汇解读】attend vt. 出席；参加attend是正式用语，侧重指参加会议、婚礼、典礼，去上课、上学、听报告等。
【活学活用】1) 只有15个人出席这次会议。2）我们都想去听李先生的报告。
Only 15 peple attended the meeting .
All f us went t attend the lecture given by Mr. Li.
My mther attended an imprtant meeting yesterday. 我妈妈昨天参加了一个重要的会议。We are ging swimming. Wuld yu like t jin us? 我们要去游泳，你想跟我们一起去吗？Will yu jin us in playing basketball? 你会和我们一起打篮球吗？I’m ging t take part in the sprts meeting. 我将要参加运动会。
【巧辩异同】attend， take part in，jin或jin in
2.D yu have anything valuable in yur schlbag? 你的书包里有贵重的东西吗？
【词汇解读】 valuable形容词，意为“贵重的；很有用的；宝贵的”，在句中可用作定语，也可用作表语。用作表语时，可与介词t连用，常用短语be valuable t sb.“对某人来说很有价值”。anything valuable 一些贵重的东西。形容词valuable修饰不定代词anything要后置。当形容词修饰不定代词(smething, anything, nthing等)时，形容词应放在不定代词的后面。
【活学活用】1) 这一经历对我很有用。2） 他在教育问题上给我们提了宝贵的建议。
This experience is valuable t me.
He gave us valuable advice n the prblems f educatin.
4. I think smebdy must have picked it up. 我想一定有人捡到。
【词汇解读】 pick up意为“拿起；捡起”。它是由“动词+副词” 构成的短语，当其宾语是名词时，该名词即可位于up之后， 也可位于pick与up 之间；当其宾语是代词时，该代词必须 位于pick 与up之间。另外pick up 还有（开车）接人; (偶然) 学会的意思。
【活学活用】1) 我的尺子在你的桌子下面，能请你帮我捡起来吗？2） 把纸捡起来然后丢在垃圾桶里。
My ruler is under yur desk. Culd yu pick it up fr me?
Pick up the paper and put it in the dustbin.
must have picked it up是“must+have+过去分词”的结构， must在此处表示推测, 意为“一定”。当情态动词后接have dne时, 表达对过去的事情进行推测, 故must have dne smething表示“过去一定做过了”这样的意思。
—Linda has gne t wrk, but her bicycle is still here. 琳达已经去上班了，但她的自行车还在这里。 —She must have gne by bus. 她一定是乘公共汽车去的。He might/culd have arrived there. 他可能早就到那里了。

情态动词表示推测的意义和用法
注意：can 表示推测通常不用于肯定句 may 表示推测通常不用于疑问句 must 表示推测通常不用于否定句和疑问句
can不肯，may不问，must 不否问

（1）情态动词表示推测时，无时态区别，只有语气差别。表示推测的情态动词的语气强弱顺序如下（由强到弱）： must ＞ can ＞ culd ＞ may ＞ might（2）含有must的句子（must表推测）变为否定句时，要用can’tHe must be at hme. →He can’t be at hme.
must，can，culd，may和might+have +V.pp表示对过去发生事情的不同推测。
They are playing chess nw. They must have finished their hmewrk.他们在下棋一定是完成作业了。
He may have knwn it already.他可能已知道了。Yu might have caught a cld. 你也许感冒了。

must，can，culd，may和might+be +V.ing表示对正在发生事情的不同推测。
亨利可能是在做梦。Henry culd be dreaming.
在反意疑问句中，当谓语动词含有must/might/can表推测意义时，疑问部分的助动词应与情态动词后面的动词在非推测情况下的用法一致。
