5. alive活着的；存在的
Who’s the greatest man alive ?
〖点拨〗alive ; living ; live ; lively ; life ; lives 这些词都有“活着”之意，它们的用法各不相同。
1）alive 意为“活着”，侧重说明生与死之间的界限，既可指人，也可指物；可用来作表语，后置定语或宾补。虽有死的可能，但还活着。例如：

He is dead , but his dog is still alive . 他死了，但他的狗仍然还活着。

二、学海导航
【学法指要】
单元难点疑点思路明晰
1. at present ; at the present time ; for the present
〖明晰〗这三个短语近义，都可表示“目前；现在”。第一个中的 present 是名词，其前不用定冠词；第二个中的 present 是形容词 ( 意为“现在的 ) ；第三个中的 present 是名词，其前要用定冠词。at present 与 at the present time 通常可互换，而 for the present 侧重指“暂时”。如：At present there are not many milu deer in nature parks in China .
We use this tense to show that something is being done at the present time .
For the present we do not need that book , so please go on reading it yourself .
2 . one day ; some day ; the other day
〖明晰〗这三个短语都可表示“某一天”，但用法不同。
( 1 ) one day 可指过去或将来的某一天，some day 只能指将来的某一天，the other day 指过去 ( 不久前 ) 的某一天。如：
At all these centres it is hoped that one day they will have enough animals to set them free and let them live in the wild again .
You\'ll be an engineer some day .
I met him the other day at the bus station .
( 2 ) 这三个短语通常作状语用，但 one day 间或能作主语用。如：
One day on the moon is as long as two weeks on the earth .
( 3 ) one day 不能连写成一个词。而 some day 有时可连写成 someday。如：
Someday we may drive cars that are run by electricity .
3 . greatly ; very ; much
〖明晰〗这组副词都可作“非常”解，主要区别是：
( 1 ) greatly 修饰动词或过去分词。如：
Since then the number of milu deer there has greatly increased .
( 2 ) very 修饰形容词和副词原级，不能修饰动词和 a - 形容词。如：
I think he\'s very old .
( 3 ) much 修饰动词、过去分词、形容词和副词的比较级或级。如：
We like it very much .
Now it is much easier to make plans for our trips .
当修饰过去分词时，much 有时可与 greatly 互换，但 greatly 的语气比较强。如：
He was greatly moved .
4. would like的用法
〖明晰〗would like 用以表示说话人委婉的愿望或请求。意为“希望，想要”等。其中 would
( 适用于各种人称 ) 可以换成 should ( 只限第一人称 ) 。在口语中，常用其缩略式“ \'d like”。其否定式为“主语 + shouldn\'t/wouldn\'t like + 其它”；其疑问式为“Would + 主语 + like + 其它 ? ”。would like 主要有如下四种结构：
1) would like +名词或代词。
— Would you like some coffee ? 你要些咖啡吗 ?
— Yes , please . 是的。
— Would you like another cup of tea ? 你还要一杯茶吗 ?
— No , thanks . 不要了，谢谢。
2) would like + 不定式。
— Would you like to have some rice ? 你要米饭吗 ?
— Yes , I\'d like to . 是的，我要。
— Would you like to have some more beer ? 你还要些啤酒吗 ? — No . thanks . I\'ve had enough . 不要了，谢谢。我喝够了。
— Wound you like to go with me ? 你愿意和我一起去吗 ?
3) would like + 主语 + 不定式 ( 作宾补 ) 。
— Would you like something to drink now ? 你现在想喝些什么吗 ?
— I\'d like a glass of beer . 我要一杯啤酒。
4) would like +不定式的完成式。
该结构含有责备或惋惜的意味。表示过去本该做某事但未能去做。
We\'d like to have helped her . 我们本该帮助她。
You\'d like to have gone there yesterday . 你昨天本该去那里。
5. Where are you travelling to , Gary ? 加里，你们打算到哪里旅行 ?
〖明晰〗该句用现在进行时表示将来，指按计划、安排在不久就要发生的动作，常用在口语中。常见的这类动词有 come , go , leave , arrive , get , start , travel , work , stay , try , fly , return 等。例如：How are you getting there ? 你们打算怎样到那里。
6 . Good luck with your trip ! 祝你们旅途好运 !
〖明晰〗Good luck . 是分手道别时的常用祝愿语，意为“祝幸运/平安/顺利”，其后常跟介词 to ( sb . ) 或 with ( sth . ) 。又如：
Good luck with your new job !
Good luck to you !
7 . Until recently , the only milu deer alive in the world belonged to …直到不久以前，世界上仅有的活着的麋鹿属于……
〖明晰〗 ( 1 ) until recently 意为“直到不久以前；直到最近”，until 在此相当于 till , 其意思是“直到……为止”，可作介词或连词，until 在此为介词。作介词时，其后常跟表示时间的名词，也可跟副词。作连词时，引导一个时间状语从句。例如：
I taught in No . 58 Middle School of Zhengzhou until 1993 .
Father usually doesn\'t go to bed until very late . 爸爸通常很晚才睡觉。
( 2 ) alive 意为“活着的；在世的”，相当于 living 或 live ( adj . 活着的 ) ，它属于
表语形容词，即只在句中作表语，不作定语。但 alive 偶尔可以作定语，要放在它修饰的名词之后。例如：
Who is the greatest man alive in the world now ?
living 和 live 作定语时，需前置。例如：living thing 生物，live chicks 活鸡
8 . In fact , there are so many deer that some are being sent to nature reserves by environmentalists who would like to return them to the wild . 其实，现在这种麋鹿已经相当多了，有一些正在被送往那些愿意把麋鹿送回野外去的地方。
〖明晰〗 ( 1 ) 该句是一个较为复杂的复合句，主句为…there are so many deer , that 引导的是结果状语从句，which 引导定语从句。
在这个 so…that 结构中，中心词是名词 deer，本应该用 such…that 结构，但因名词前有 many 修饰而用了 so…that 结构，此特殊用法需注意。
( 2 ) are being sent 是现在进行时的被动语态形式，表示“正在被送往”其中的 being 容易被误省。又如本课中的其它两句：
The life of the milu deer is being studied there .
More milu deer are being moved to a new large nature park in Shishou in Hubei Province .
【妙文赏析】
Two Mistakes
For a long time Dr Smith had wanted to get a better job in a certain big modern hospital . He was appointed to a particular position which he wanted , and his wife moved to the house which they were now to live in . The next day some beautiful flowers were sent to them , with a note which said , “ Deepest sympathy (沉痛悼念). ” Naturally , Dr Smith was angrily to receive such an unusual mote , and telephoned the shop which had sent the flowers to find what the note meant . When the owner of the shop heard what had happened , he apologize to Dr Smith for having made the mistake .
“ But what really worried me much more , ” he added , “ is that flowers which ought to have gone to you were sent to a person who had just died , with a card which said , ‘Congratulations on your new position . ’ ”
很久以来，史密斯医生一直想在某一家大型的现代化医院找一份比较锡样的工作，这一天终于盼来了。他被任命为他想干的特殊位置，而他的妻子也搬进了他们现在住的房子。第二天送来一些鲜花，里面夹着一张条子，上面写着： “ 沉痛悼念 ” 。
接到这样一张奇特的字条，史密斯医生自然很生气，于是便给鲜花店打电话询问怎么回事。
当店老板听说发生的情况时，他忙向史密斯医生道歉，说是送错了。
“ 但真的使我更担心的是， ” 他补充道， “ 本应该送到你那里的鲜花却送给了一个刚死的人，鲜花里面夹着一张卡片，上面写着：‘祝贺你搬迁新居。’ ”

三、智能显示
【心中有数】
单元语法发散思维
一、现在进行时的被动语态
〖思维〗1. 现在进行时的被动语态结构。
I am/ He / She is/ You / We / They are + being done .
More milu deer are being moved to a new large nature . 更多的糜鹿正被往一所新建的大天然公园迁移。
2. 现在进行时的被动语态的用法。
A . 表示一个正在进行的被动动作即某件事情现在正在被做。例如：
The water is being turned into vapour . 水正在变成蒸汽。
The question is being discussed at the meeting now . 现在会上正在讨论这个问题。
B . 表示在现阶段进行被动动作，但不一定发生在说话的这一时刻。例如：
The bridge is being repaired .那座桥正在修复之中。(可指“正在讲话的同时”，也可指“目前”。)
She\'s being taught English . 有人在教她英语。(在说话时，也许根本没人教她。)
［注］现在进行时的被动语态有时可与情态动词连用。如：
I know Mark was going to have an interview sometime this afternoon . He may be being interviewed at this very moment . 我知道马克今天下午什么时候有面试。他此刻也许正在接受面试哩。
练习：
A . 把下列句子变成被动语态。
1 . Mr Smith is driving a car .
2 . The teacher is scolding (批评) me .
3 . They are painting the houses .
B . 单项选择。
4 . — Have you moved into the new house ?
— Not yet . The rooms ____ .
A . are being painted B . are painting C . are painted D . are being painting 5 . I ____ English for five years now .
A . was studying B . have been studying C . studied D . am studying

8 . In some parts of the world , tea ____ with milk and sugar .
A . is serving B . is served C . serves D . served
答案：1. A car is being driven by Mr Smith . 2. I am bing scolded by the teacher . 3. The houses are being painted . 4 — 8 ABCDB
二、enough 与高考
Ⅰ . enough 作副词用时，可修饰形容词、副词和动词。修饰形容词、副词时，enough 应后置。
Helicopters were sent to rescue them , but it was impossible for them to get close enough .
When they reached the burning building they found that their ladders were not long enough to reach the people who were trapped .
You don\'t practise enough at the piano .
I with you\'d write clearly enough for us to read it .
Ⅱ . enough 作形容词用时，修饰复数名词和不可数名词，习惯置于名词之前。
Have you made enough copies ?
I\'ll get enough money to pay for a taxi .
当 enough 和形容词一起位于名词之前时，要注意辨别 enough 的词性以及对语义的影响。比较：
1 . a) I haven\'t found enough big nails to mend the cupboard . 我还没找到足够的大钉子来修碗柜。
b) I haven\'t found big enough nails to mend the cupboard . 我还没找到足够大的钉子来修碗柜。
a) 句中的 enough 是形容词，修饰 nails，强调钉子的数量。b)句中的 enough 是副词，修饰 big，强调钉子的大小。
2 . a) Is there enough hot water for me to have a bath ? 有足够的热水让我洗个澡吗 ?
b) Is there hot enough water for me to have a bath ? 有足够热的水让我洗个澡吗 ?
a) 句中的 enough 是形容词。修饰 water , 强调数量；b)句中的 enough 是副词，修饰 hot , 强调水的温度。
下面请看 NMET1998 — 11题。
If I had _______ , I\'d visit Europe , stopping at all the small interesting places .
A . a long enough holiday B . an enough long holiday
C . a holiday enough long D . a long holiday enough
选项A中的 enough 是副词，修饰 long，强调程度，符合句意，故是句意，故是答案。B中的 enough 是形容词，不能修饰单数可数名词，故不选。选项C、D的语序不对，也不可选。
