一、目标再现
在本单元中要求学生对在前面五单元中所学过的知识做一次全面的回顾和总结。复习、归纳一般过去时态和现在完成时态,进一步学习动词不定式和宾语从句。能够区别 have been与 have gone的用法;重点学习课文/"Under the sea/",明白How important is the sea to our life?
通过利用computer去寻找一些information,进一步熟悉有关如何操作计算机的术语;掌握数词的用法和类似 thousands of短语的用法。通过该单元的学习,要使学生明白海洋对于我们人类的重要,人类与自然应当和谐相处,并尽力保护它的环境。
二、重点难点解析
1. Not too long ago, people couldn’t go scuba diving on Hainan Island, or anywhere else.
不久以前,在海南和其他地方人们还不能进行潜水运动。
else 形容词,意思为“别的;其他的”,无比较级。
它常接在疑问代词,不定代词后面。如:
— Beside the weather, what else did he say? 除了天气,他还说了些什么?
— Who else is coming? 还有别人来吗?
— Anything else I can do for you? 我还能为你做些别的事吗?
2. This is because there was no machine allowing a person to breathe under water for a long time. 这是因为没有供人水下呼吸很长时间的机器。
allow sb. to do sth. 意思为“允许某人做某事”。 相当于宾语时,必须接不定式。如:
They don’t allow children to go into that room.=They don’t let children to into that room.
他们不允许孩子进入那个房间。
I allowed him to use my room.=I let him use my room. 我让他使用我的房间。
当allow后接不接人称代词或名词时,后面的动词须用 –ing 形式,而不能用不定式。如:
My parents don’t allow us to smoke. Smoking is not allowed both at home and at school.
我父母不允许吸烟。
注意:这一用法中的allow不能用let替换。
3. In 1943 Jacques Cousteau and his friend made it possible by inventing the scuba machine.
1943年雅克•库斯托和他的朋友发明了水下呼吸器,才能使这成为可能。
make在这里是“使得”的意思,后接不带to的动词不定式。“make sb. do sth.” 意为“让 / 使得某人做某事”。make后还可以跟形容词作宾补。如:
The boss made the workers work twelve hours a day. 老板让工人们一天工作十二小时。
His mother was ill. This bad news made him sad.他的母亲病了,这个坏消息使他很难过。
4. He was amazed at all the colours, and all the beautiful fish.
他对五颜绿色和各种美丽的鱼感到惊奇。
amazed 使(某人)感到惊奇。
She amazed us by dancing so beautifully. That’s why we enjoyed every minute of the party.
她舞跳得如此美,使我们很惊奇,这也使我们聚会时度过了美好时光。
be amazed at / by 感到惊奇。如:
We are amazed at the changes in Beijing. I can’t even find where my old house is.
北京的变化使我们感到惊奇。我几乎找不到旧房子了。
She was amazed by what she saw in China. She is now planning to bring her whole family here next month.
她在中国所见到的情景使她感到惊奇。她正打算下个月把家人都接来。
5. However, when he returned some years later, the colourful coral reefs were dead and grey.
然而,多年以后,当他回来时,艳丽多彩的珊瑚礁已经死了,变成灰色的了。
however conj. 然而;可是;不过;但是
Certainly he agreed. However, I won’t agree,
他当然同意了,然而我不同意。
注:however与but的区别在于,前者较为正式,but不能置于句首,而however 可以置于句首,句中或句末。置于句中时,前后用分号隔开的情况较多。
6. Since water covers most of the earth, Corsteau knew we should keep the seas clean.
由于水覆盖了地球的大部分,库斯托知道我们应该保持海洋清洁。
(1)since与because的区别在于,since常用于指众所周知的原因,而Because常用来回答Why的提问。
Since we are young, we should do more for our country.
既然我们年轻,我们应当多为国家做事。
— Why is Kate absent? 凯特为什么迟到了?
— Because she is ill. 因为她病了。
(2)本句中cover的用法,意思是“用……遮盖;覆盖”。
Snow covered the ground. 雪覆盖了地面。
She cried and covered her face with her hands. 她哭了,用手蒙住了脸。
The desk was covered with dust.=Dust covered the desk. 书桌上布满了灰尘。
7. …, he encouraged everyone to take part in protecting our lakes, rivers, seas and oceans.
……,他鼓励每个人加入到保护我们的河流、湖泊和海洋的行动中来,take part in意为“参加(活动)”一般表示在活动中还承担一定的职责。
He always takes an active part in all kinds of activities in school.他总是积极参加学校各种活动。
join也有参加的意思,但是该词主要强调参加某项组织。如:He joined the party when he was eighteen years old.他十八岁就入了党。
8.— … but I’ve gone scuba diving. — So have I.
— ……但是我去潜水了。 — 我也去了。
“So+be/情态动词/助动词+主语”这种简略结构表示“某人也……”如:I like green very much. So does Lily. 我喜欢绿色,莉莉也喜欢。
Tom can swim, so can I. 汤姆会游泳,我也会游。
She is a student. So are they. 她是学生,他们也是。
I went to the zoo yesterday. So did Mary. 昨天我去了动物园,玛丽也去了。
so+主语+be/情态动词/助动词,这种结构强调“……确实如此”。如:Her husband is English. So he is. 他丈夫是英国人。是的,他是。
Tom studies very hard. So he does. 汤姆学习很努力。是的,他确实很努力。
She passed the exam. So she did. 她通过了这次考试。是的,他确实通过了。
9. I’ve been down as long as two hours. 我在水下待了两小时之久
as long as …长达……
It took us as long as four hours to get over the mountain.我们花了四个小时才翻过了那座山。
Mr. Brown spent as long as two and a half years writing the novel.
布朗先生花了长达两年半的时间才写完这部小说
注:类似的用法还有as much as, as large/big as, as wide as, as high as等等。如:
Look at the tower, it is as high as sixty metres. 看那座塔,它高达60米。
I spent as much as ten thousand yuan on the piano. 买这架钢琴,我花了多达一万块钱。
注意:as long as这个短语还可以做从属连词用来引导条件状语从句。意思是“只要……”,也可以说;so long as。如:As long as I live, I’ll study. 只要我还活着,我就要学习。
You may borrow the books so long as you keep it clean.
只要你能保持书的清洁,你就可以借书。
As long as we don’t lose heart, we’ll find a way to overcome the difficulty.
只要我们不灰心,我们就能找到解决问题的出路。
10. Maybe we can go scuba diving sometime. 也许改天我们能潜泳。
Maybe it will rain tonight. 可能今天晚上会下雨。
Maybe it is true. 也许这是真的。
It may be wrong. 这可能有错。
11. Not all sharks are alike. 并不是所有的都相似。
alive adj. 意思为“相同的;相像的”常做表语。
They were born on the same day. The two brothers are very much alike.
他俩出生于同一天。这兄弟俩长得很像。=They were born on the same day. The two brothers are very like. 他俩出生于同一天。这兄弟俩长得很像。
注意:like 之前可以用very 来修饰,但是alike之前则不行。另外,alike也可以用做副词。如: You and I think alike.你和我的想法一致。
Great minds think alike. 英雄所见略同。
12. … but many sharks feed on fish, other sea animals, smaller sharks and sometimes people.
……许多鲨鱼以鱼和其他的海洋动物,较小的鲨鱼为食,有时还以人为食。

类似的句型还有:

It is known that … 众所周知……
It is reported that … 据报道……

关于现在完成时态的归纳
1. 现在完成时态的结构have/has+过去分词
2. 现在完成时涉及两个时间概念。一是过去,二是现在。谓语动词虽然所表示的动作发生在过去,但是该时态所强调的还是对现在的影响或结果。关键在于这种影响和结果正是说话人的兴趣所在。因而,该时态通常不带有时间状语。如:
The boy has come back. 孩子回来了。(意思是说孩子在家。)
I’ve lost my pen. 我把钢笔给丢了。(意思是说我现在没有钢笔用。)
3. 现在完成时态还可以用来表示开始于过去,且该状态一直延续至今而且还有可能继续下去的可能性的情况。谓语动词的动作通常是可持续的。如:
I have lived here for more than twenty years. 我在此住了二十多年了。
Nothing has happened ever since. 打那以后就什么也没有发生过,
4. 非延续性动词用于现在完成时态的时候,通常不带表示时间段的时间状语,因此不和for或者since连用。例如,不能说:I have bought the house for two years / since two years ago.
而应当说:I bought the house two years ago.
或者说:I have had the house for two years.
或者说:It’s two years since I bought the house.
但是非延续性动词的否定式可以和表示一段时间的时间状语连用,表示这种动作的否定状态的延续。如:I haven’t bought anything for a week / since you left.
我已经有一个礼拜没有买东西了。/自从你离开以后我没有买过任何东西。
5. 同学们应当特别注意的是,现在完成时态是一个属于现在时态的范畴,所以它可以和包括“现在时刻”在内的时间状语连用。如:
Now, today, this morning / week / month / year, by now, so far, up to now, already, before, just, ever, never, always, recently, lately.等等。如:
I have done nothing today. 我今天什么事情也没有干。
We have had four lessons this morning.
今天上午我们上了四节课。(说话时还没有超出上午的范围)
Have you seen her before? 你以前见过他吗?
6.当强调行为的行为时间、执行者、行为方式、行为场所、行为原因时,句中一般用一般过去时,而不用或者很少用现在完成时,间或用现在完成时也是为了强调结果。如:Who did it? How did he do it? Why did he do it? Where did he do it? When did he do it?

三、典型例题解答与分析
例1 I don’t think the girl is right, ________ ________?
A. do I B. is she C. isn/'t she D. does she
解析 答案B。一般来说含有宾语从句的句子改为反意疑问句时,疑问部分常与主句的主谓语要一致,但主句的主语是第一人称时,疑问部分常与从句的主谓要一致。本句中从句的动词为be,且前面表示否定,这样A、C、D都不合题意,B是正确答案。
例2 单项选择填空
( ) 1. The old writer lives ________, but he doesn/'t feel ________.
A. alone; alone B. alone; lonely C. lonely; lonely D. lonely; alone
( )2. There are bookshops on ________ side of the street. _________ of them do not close till midnight. A. both; All B. every; None C. either; Some D. other; Many
( )3. I don’t like this movie, ________. A. either B. neither C. too D. also
( ) 4. I don’t know if he ________ tomorrow. If he ________, I’ll call you.
A. comes; comes B. will come; will come C. will come; comes D. comes; will come
解析
1.B. alone可用做副词,意思是“单独的;独自的”。形容词lonely可作表语,意思是“孤独的;寂寞的”,指心理上感到寂寞、孤独等。
2.C.“在街道两边”要说on half sides of the street或者 on either side of the street。选项 A中的 both不能接side。选项B中的every表示三者和三者以上的每一个,故B不符合题意。如果要表达“在街道的另一边”应为on the other side of the street。选项D中other前没有冠词the.因此选C。
3.A.either和too意思均为“也”,做副词用时放在句末,但either用在否定句中,too和also用在肯定句中。
4.C.第一个if引导的是宾语从句,主句谓语动词的时态用现在时,从句可用现在时或将来时。第二个if引导的是条件状语从句,谓语动词的时态要用现在时表示将来。句中tomorrow提示从句应用将来时,所以选C。
例3 下列各句A、B、C、D中有一处错误,将错处序号填入题前括号内并在后面横线上写出正确的答案
( ) 1. How long have the Whites arrived in China?________
A B C D
( ) 2. Wang Qiu was too tired to do something else by then.________
A B C D
( ) 3. I could hear him speaking to myself in the sitting - room .________
A B C D
( ) 4. The plane arrived in nine past nine the day before yesterday.________
A B C D
( )5. He could able to tell us what had happened over there.______
A B C D
( )6. Tom is well at English, but a little weak in Chinese.________
A B C D
解析
1.C,been。arrive是终止性动词,不能和表示长度的时间状语连用,应将arrive改为持续性动词。
2.B,anything。因too…to结构中不定式具有否定含义,所以应将不定代词something改为anything。
3.C,himself。此处的意思是自言自语,那么自身代词就应与前面发出动作的人称代词相一致。
4.B,at。表示在时间的某一点上用at,in通常表示在某个时间范围内。
5.A,was able to,can与be able to在一般情况下可以互换使用,但两者无论在任何情况下都不能合用。
6.A,good,be good at是个固定词语,它相当于do well in,两者中间的good与well不能混用。
例4 就下列各句划线部分提问
1) My mother paid fifty yuan for the skirt.______ _____ did your mother ______ for the skirt?
2) I don’t like summer because it’s too hot. ________ ________ you like summer?
3) I have been to Shanghai twice. ________ ________ ________ have you been to Shanghai?
4) It’s going to be rainy tomorrow.____ _____ the weather going to ____ _____ tomorrow?
5) Sam has stayed in Beijing two months.______ _____ months has Sam stayed in Beijing?
6) All that afternoon Ted jumped and sang all kinds of songs.
________ ________ Ling Feng ________ all that afternoon?
解析
就谓语提问时,无论是及物动词带宾语或是不及物动词,问句都以what开头,并以do的适当形式代替谓语动词。同时,助动词也要根据需要变化形式。就宾语提问时,表示人的疑问词用whom或who,表示物的用what或which。就状语提问时,表示时间的通常用when,表示地点的用 where,表示原因的用why,表示程度或方式的用how。就定语提问时,修饰主语的,问句语序不变,就修饰宾语或表语的定语提问,必须把代替它的疑问词和它所修饰的词一起提到句首。问谁的用whose,问哪个用which或What,问数量用how many(可数)或how many(不可数),问次数的用how many times等。
答案为: l) How, much, pay 2) Why, don’t 3) How, many, times.
4) What, is, be, like 5) How, many 6) What, did, do 7) How, old
