知识构建8
一、短语盘点。
1.belong to属于 2.attend a concert参加音乐会 3.something valuable贵重的东西 4.at the picnic在野餐时 5.pick up捡起；拾起 6.run away逃走 7.have fun doing sth.做某事很开心 8.prevent...from doing sth.防止……做某事；阻止……做某事 9.at the same time 同时；一起municate with sb.和某人交流
二、重点句型。
1.I think somebody must have picked it up.我想一定有人捡到它了。
2.He might be running to catch a bus.他可能是在追赶公共汽车。
3.There must be something visiting the homes in our neighborhood，but what is it？一定有什么东西闯入了我们小区的住宅，但会是什么呢？
三、交际用语。
1.Whose volleyball is this 这是谁的排球？
2.It must be Carla's.它一定是卡拉的。
3.Why do you think the man is running 你觉得那个男的为什么跑？
4.He could be running for exercise.他可能是在跑步锻炼身体。
四、语法聚焦。
1.see sb.doing sth.意为“看见某人正在做某事”。
2.see sb.do sth.意为“看到某人做某事”。
3.“not only...but also...”意为“不但……而且……”。
4.情态动词表示推测的用法。
（1）不同时态的用法：“情态动词+do sth.”表示对现在事情的推测；“情态动词+be doing sth.”表示对正在发生的事情的推测；“情态动词+have done sth.”表示对过去发生或已完成的事情的推测。
（2）肯定推测：①must用于肯定句，表示较有把握的推测，意为“准是；一定”，后面接动词原形，表示对现在的推测。②may用在肯定句中，表示对现在把握不大的推测，意为“也许；可能”。③could、might也可表示推测，常用在过去时中，但在某些场合，为了使语气更缓和、更委婉，常用could、might代替can、may。④can用在肯定句中，表示理论上的可能性。
（3）否定推测：①表否定推测时，can't/couldn't语气最强，指“不可能”，带有惊异、怀疑的感彩。②语气不很肯定时，常用 may not或 might not表否定推测，意为“可能不；也许不”。
（4）疑问句中的推测：常用can或could，意为“可能”。
五、易错点提醒。
1.belong to意为“属于”，后接名词或代词，但不能接名词所有格。
2.anything valuable意为“一些贵重的东西”，形容词valuable修饰不定代词anything时要后置。形容词修饰不定代词（something、anything、nothing等）时，应放在不定代词的后面。
六、写作指导。
1.话题分析。
本单元的写作是根据所提供的材料进行推测和判断，看看某件物品有可能是谁的，以及利用情态动词表示推测，判断物品的归属。在写这样的文章时，要注意以下几点。
（1）围绕所给提示，确定写作要点。
（2）按照可能性的大小，正确使用表推测的must、can（否定形式can't）、could、might、may等情态动词做出合理推测。
（3）如果是对现在或将来的情况进行推测和判断，可用“情态动词+do”；对现在或将来正在进行的情况进行推测和判断，可用“情态动词+be doing”；对过去情况的推测和判断，可用“情态动词+have done”；对过去正在进行的情况的推测和判断，可用“情态动词+have been doing”。
（4）使用合适的连词和副词，避免文章简单地重复，如then、also、so、and、but等。
2.常用表达。
（1）Whose...is it 这是谁的……？
（2）It must be... 它一定是……
（3）It might belong to... 它可能是……
（4）It can't be... 它不可能是……

1.happen是不及物动词，它的用法如下。

例：An accident happened in that street.那条街上发生了一起事故。
（2）表示“某人出了某事（常指不好的事）”要用“sth.+happened+to sb.”这一结构。
例：A car accident happened to her this morning.今天上午她出了车祸。
（3）表示“某人碰巧做某事”要用“sb.+happened+to do sth.”这一结构。
例：I happened to meet a friend of mine in the street yesterday.昨天我碰巧在街上遇到了我的一个朋友。
