知识概要
课时讲练
1.Whose book is this 这是谁的书？
whose意为“谁的”，在句中作定语，引导疑问句时，所修饰的名词可以紧接whose，也可以放在后面。例如：
Whose notebook is green 谁的笔记本是绿色的？
Whose jacket is this = Whose is this jacket 这是谁的夹克衫？
【注意】who, whom和whose这几个同源词的用法区别：who通常作主语; whom通常作宾语; whose通常作定语。
Section A（第一、二课时）
It could be Mei’s hair band. Or it might belong to Linda.它可能是梅的发卡。或者它可能是琳达的。
I’m not sure，but it can’t be a dog. 我不太确定，但是它不可能是一只狗。
本单元重点学习情态动词表示推测的用法。
2.It must be Mary’s.它一定是玛丽的。
（1）肯定的推测一般用must, should, may（might）或could（不用can），其中，must的语气最强，意为“肯定，准是，想必是”; should的语气次之，意为“很可能，应该”，指按常理推测; may（might），could的语气最弱，意为“也许; 可能”。例如：
He must/should/may/could know the answer to this question. 他一定/应该/可能/也许知道这个问题的答案。
（2）否定推测分为两种情况。
①语气不是很肯定时，常用may not, might not或could not，意为“可能不; 也许不”。例如：
She may not go to the museum. I’m not sure. 她也许没去博物馆。我不太确定。
②否定语气较强时，则用can’t，意为“根本不可能; 想必不会”。例如：
It can’t/couldn’t be Miss Wang. She has gone to Shanghai for a meeting. 这不可能是王老师，她去上海开会了。
（3）疑问句中的推测，往往用can或could。例如：
Could she have finished the task 她可能把任务完成了吗？
Can she be in the library now 她现在可能在图书馆吗？
（4）对已发生事情的肯定推测常用“must/ may/ might等+完成式”; 否定推测常用“can/ could/ may/ might等+not+完成式”。例如：
It must / may / might / could have snowed last night. The ground is white.
昨晚肯定/可能/也许下雪了。地面是白色的。
The door is locked. She can （could）not / may （might）not have been at home. 门锁着，她不可能/可能不在家。
（5）对现在或将来的推测，情态动词后一般接动词原形; 若表示对正在发生的情况的推测，用“情态动词+be+现在分词”; 若要表示对过去的情况进行推测时，用“情态动词+ have + 过去分词”。例如：
He must be reading newspapers in the reading room now. 他现在一定在阅览室看报纸。
He must have arrived there already. 他一定已经到了那里。
3.Do you have anything valuable in your schoolbag 你的书包里有贵重东西吗？
句中valuable修饰不定代词anything。修饰不定代词的形容词要后置。例如：
Do you have anything special to tell me 你有不寻常的事要告诉我吗？
There is something important to read in today’s newspaper. 今天的报纸上有一些重要的信息可以读。
4.Every night we hear strange noises outside our window. 每天夜里，我们听到窗户外有奇怪的声音。
noise意为“噪声”时，通常为不可数名词; 意为“间断的或者一声声的响声”时，通常为可数名词。例如：
Stop making so much noise.别制造这么多噪声。
Suddenly there was a big noise in the garden. 突然，花园里有一声巨响。
【辨析】noise, voice与sound的用法区别。
①noise侧重指“噪声，嘈杂声，吵闹声”，一般指不悦耳、不和谐的声音。例如：
The noise of traffic kept her awake.车辆的喧闹声使她睡不着。
②voice作“声音”讲时，多指人发出的声音，包括说话声、歌声和笑声等。例如：
Betty has a beautiful voice.贝蒂的嗓音很美。
③sound意为“声音，响声”，泛指在自然界中所能听到的任何声音。例如：
Light travels much faster than sound.光的传播速度比声音快得多。

【辨析】receive和accept的用法区别。
（1）receive和accept都有“收到”的意思，但用法有差别。receive表示接到他人交给你的东西，是客观上的“收到”; 而accept意为主观上“接受”，表示不仅收到，而且愿意接受这个东西。例如：

Frank received a tablet from his friend, but he didn’t accept it because it was too expensive.弗兰克收到了一台朋友送给他的平板电脑，但他没有接受，因为太贵了。

We were warmly received. 我们受到热情接待。
2.They think the stones can prevent illness and keep people healthy. 他们认为这些石头能预防疾病，使人健康。
prevent作动词，意为“阻止，阻挠，预防”。prevent sb. from doing sth. 为固定搭配，意为“阻止某人做某事”。例如：
In winter，gloves can prevent our hands from getting cold.在冬天，手套可以防止我们的手变冷。
Nobody could prevent me from solving the problem.没有人能阻止我解决这个问题。
【拓展】“prevent...from...”常可与“keep...from...”和“stop...from...”换用。例如：

三、阅读理解。
Sometimes people come into your life and you know at once that they were sure to be there. They serve some sort of purpose, teach you a lesson or help find out who you are or who you want to become. You never know who these people may be: your classmate, neighbor, teacher, long-lost friend or even a real stranger. But you know that every moment they will affect your life in some serious way.
Sometimes things happen to you. At the time they may seem terrible, painful and unfair. But later you realize that without getting over those difficulties you would have never realized your further ability and strength. Everything happens for a reason and nothing happens by chance or with good or bad luck.
The people you meet affect your life, and the successes and failure you experience, create who you are. Even the bad experiences can be learned from. In fact, they are probably the most poignant and important ones.
Enjoy every day even every moment and take from it everything that you possibly can, for you may never be able to experience it again. Talk to people you have never talked to before, and really listen. You should set your sights high, hold your head up, tell yourself you are a great one and believe in yourself.
You can make your life anything you wish. Create your own life and then go out and live it.
根据短文内容，选择正确答案。
（ ） 1.The people we meet ________.
C
A.serve us on no purpose
B.all know where to find us
C.will change us in some way
（ ） 2.From the passage, we know that bad things can make us
________.
C
A.find no serious success
B.possibly enjoy every moment
C.realize our further ability
（ ） 3.What does the underlined word “poignant” in the passage mean in
Chinese
A
A.深刻的 B.平淡的 C.艰苦的
（ ） 4.The writer’s advice is that we should ________.
C
A.not believe in ourselves but others
B.get over difficulties painfully
C.learn as much as we can each day
（ ） 5.What might be the best title for the passage
B
A.Hold your head up B.Create your own life C.Things happen to you
四、书面表达。
假如你家的那只3 个月大的宠物猫欢欢3天前走失了, 到现在还没找到，她可能会到哪去呢？她可能在某个地方和其他猫玩; 她可能遇到好心人，被送到警察局; 她可能在街上闲逛，想找到回家的路; 它还可能正在一个温暖的地方睡觉。你们一家人都很着急，希望能早点找到它。请你写一篇英语短文，对宠物猫欢欢的现状进行推测。80词左右。
______________________________________________________________
________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
One possible version:
My pet cat Huanhuan is only three months old. She got lost three days ago. Where is she now
I guess she might be somewhere playing with other cats. Or maybe a kind person found her and took her to the police station. Or she might be hanging out on the street trying to find her way home. It’s also possible that she is sleeping in a warm place.
Everyone in my family is worried about her. We hope she comes back home soon.
