二、学海导航
【学法指要】
单元句型思路明晰
1. Even when + 从句
Even when you are asleep , you are using energy . 甚至在你睡觉时，你也在消耗能量。
〖明晰〗even 作为副词放在由when引起的时间状语从句的前面起加强语气的作用。
Even when it is in August , the weather there is very cold .
Even when he was taking a holiday he was worried about his work .
2 . 主语 + be considered + to be + 主语补足语
The Chinese diet is considered to be the healthiest in the world . 中国饮食被认为是世界上最健康的饮食。
〖明晰〗consider 做“认为”时可以带不定式的复合结构，即：主语 + consider + 宾语 + 不定式（主要是 to be 做宾语补足语）。如果将宾语变为主语，则 consider 用被动语态，原来作宾补的不定式便变成为主语补足语。注意：to be 常常被省略后成为：consider + 宾语 + 名词（或者形容词）。
He considered the task to be the most difficult one . → The task was considered to be the most difficult one by him .
We all consider his suggestion to be reasonable . → His suggestion is considered to be reasonable .
We consider this (to be) a useful book . → We consider this book useful .
单元难点疑点释疑
1 . When playing football or basketball , you might be using 400 calories an hour . 踢足球或者打篮球时，你每小时可能要消耗 400 卡能量。
〖释疑〗连词 when , while 引起的时间状语从句，如果从句中的主语与主句中的主语是同一人或物时，则可以省略主谓语，变成“When / while + ing”这中结构。
While he was doing the experiment , he noticed something strange . = While doing the experiment , he noticed something strange .
2 . In some parts of Britain , one person in ten , by the age of thirty , has no teeth left . 在英国有些地方，十分之一的人年方三十，牙齿就掉光了。
〖释疑〗 one person in ten 即 one person in ten persons 的省略，其意思为“十个中有一个人”。与 one person in ten 类似的结构有：one person out of ten , one out of ten persons 。但是，ten to one 是“十有八九，很可能”。
Two teachers in ten are against this plan .
Three out of four people (= Three fourths of the people ) went there to have a look .
It will rain tonight ten to one .
另外，left 为过去分词作定语修饰 teeth ，其意思是“剩余的”。
There is but one chance left . 只剩下一个机会。
3 . scores of people went there in the first few days after its opening . 开张的头几天，许许多多人到那家餐馆去就餐。
〖释疑〗after 为介词，其后的物主代词所有格 its 及名词 opening (开张，开幕；开放)构成介词短语作状语。in the first few days “在头几天里”，这里，the first 不是“第一”，当其后接复数名词时，意思是“头几个，第一批”。
I was one of the first people to visit the newly built factory .

答案：1 ― 5 DDAAB 6 ― 10 CBBDD 11 ― 15 DABAD 16 ― 20 CABAB 21 ― 25 C
赏析：1 . D . 根据句意，需要填数词，the 后面跟序数词。2 . D。out 和 find 搭配是“发现、弄清”的意思。根据上一句话，他们当中的一个人去“the Information Center”，目的就是为了弄清火车开车的时间。3 . A。three 和 o\'clock 连用是三点钟。4 . A。根据上文，他把火车延期这件事告诉了他的朋友。“delay”是延期之意，而 aident 是突发事件，tickets 是票，lateness 是“迟”的名词形式，均不合题意。5 . B。suggest 作“建议”解，后接从句，从句用虚拟语气“should + 动词原形”，should 可以省略。6 . C。so位于句首，引起倒装，go 与 off 连用是“去”之意；而 go on 是“继续”的意思；go in 是“进入状态”之意；go that 不是固定搭配，无词意。7 . B。他们三人进了酒巴，等了一会之后，故选 later。8 . B。track 是“铁轨”之意，与“rail”同义。stop 意为“停止”或“公共汽车站”；station 意为“火车站”；way 是“方法、道路”。此处说的是他们到了上火车的站台，也就是这列火车所在的铁轨处。9 . D。根据下文，三个人都 shouting , “Wait ! e back!”，一定是火车离开了车站，故选out of。10 . D。因为火车已经开走，所以三个人只能跟在后面。11 . D。catch up with 为固定搭配，是“赶上”之意。12 . A。seize 作“紧抓”解；hold 意为“握住”；take意为“拿”；shake 意为“摇动”。由于他们迫切的心情，所以此刻一定要抓住。13 . B。pull 与 up 搭配是使他们能够跟住火车，而 pull on 是“戴上”的意思，pull off 是“脱下”的意思，pull in 是“车进站”的意思。14 . A。by 指“在这个时候”；till 表示时间时，指“到……时”；而 at this time 提“在此刻”；till 用于肯定句，与延续性动词连用；since 是“自从……”的意思，不合题意，因为三个人从追火车到此时是有一段时间的，故答案应选A。By。15 . D。stop doing something 是停止做某事，因为第三个人赶不上火车了，只好不跑了。stop to run 是停下来去跑的意思，不符合题意。16 . C。watch 后接不带 to 的动词不定式作宾语补足语。17 . A。空白处的动词和 wave 相并列，hear 指听见，而 listen to 指听的动作。C和D不合题意。故答案为A。18 . B。on his face 意为“在脸上”，指表情。19 . A。moment 片刻，minute 分钟。此时应该是过了片刻，而不是一分钟。故答案选A。20 . B。用 and 连接两个并列成分。21 . C。standing 是现在分词作定语，修饰 A man。其他三项不能作定语。22 . C。funny 是“滑稽、可爱”的意思。那个人看见两个人上了火车，第三个人没上去还大笑，便觉得可笑。23 . C。after 与 all 搭配，表示“毕竟”的意思。24 . C。so… 与 that 连用，表示“如此……以至于”。25 . C。see somebody off 意为“给某人送行”，see somebody out 意思是“把某人送到门口”，不合题意，see 与 away 搭配不成立，see 与 leave 搭配是不和题意的。
【思维体操】
On Sunday morning , a priest（牧师） told the people 1 . _____
ing in the church that their church was in need of 2 . _____
repairs . Some of them said they would glad to give 3 . _____
five or ten dollars each in order that make the repairs . 4 . _____
But the richer man in the town only stayed in his seat 5 . _____
and said nothing . Suddenly a small piece of ceiling 6 . _____
fell down right in the rich man\'s head . He stood up 7 . _____
at once and said that he would give out ten dollars . An 8 . _____
old man in the back looked down toward the ceiling and 9 . _____
said“Hit him again !”All the people were laughed . 10 . ____
答案：1. On → One。这里不是泛指星期天上午，而是具体的一个星期天的上午。 2. in → into 。3. would 后加 be 。因 glad 是形容词。4. that → to 。5. richer → richest 。因比较的范围是“in the town”。6. √。7. in → on 。8. 去out 。9. down → up 。10. 去掉 were 。此处是在场的人都笑了，而并非被嘲笑。

单元语法发散思维
倒装句用法归纳
〖思维〗倒装的原因是语法结构的要求，或是为了或调。倒装句的类型有：
1 . 全部倒装 (即整个谓语结构放在主语前面)
(1) “There + be + 主语 + 其它”。本句型主要表示“有，存在；出现”等概念。
There is no desk in the room .
(2) “There (Here , Now , There) + e (go 或 be) + 主语”。这里的 There , Now 等并不指具体的地点和时间；除 then 外，其余句子均用一般在时。
There es the bus .
但如果这时的主语是人称代词时，主谓不倒装。如：Here he es .
(3) 直接引语的全部或一部分放在句地，其结构是“直接引语 + 谓语 + 主语”。如：
“Let\'s go , ”said he .
(4) “方位词 + 不及物动词 + 主语”。其常用的动词有go , e 等。如：Away went the boy .
但是如果主语是人你代词时，主谓也不倒装，可将上句改为：Away he went .
(5) “地点状语 + 谓语 + 主语”。
In front of the house sat a small boy .
(6) “so + 助词 + 主语”。常用的助词有 be (是) ，have (有) ，助动词或情态动词。这一句型是对前面内容的肯定，表示“另一个 (或物) 也一样”。如：
― He is a student .
― So am I .
― He likes skating .
― So does she .
但是，如果两句主语指的是同一个人或物时，主谓要用正常语序，即谓语要放在主语后。如：
Son :“You promised to buy me a dictionary . ”
Father :“So I did .”
(7) “Neither (nor) ”+ 助词 + 主语”。这一句型与上一句型基本相同，只不过其意思是表示否定而已。如：I couldn\'t do it . Neither could he .
(8) 为避免句子头重脚轻而将表语前置，其结构是：“表语 + 系动词(可加上助动词) + 主语 + 其它”。Such would be our home in the future .
2 . 部分倒装 (即部分谓语放在主语之前)
(1) “否定词 + 谓语第一部分 + 主语 + 谓语第二部分 + 其它”。常用的否定词有never , seldom , little等；谓语第一部分通常是be , have , 助动词或情态动词。Never could I fet the days .
如果没有前面提及的谓语第一部分，则需要加上do，或 does 或 did，且后面的动词要用原形。如：
Little did she know that she was very ill .
(2) “Only + 状语 + 谓语第一部分 + 主语 + 谓语第二部分”。但在这一句型中，主句倒装而从句不倒装。
Only after being asked three times did he answer me .
Only after he finished his task did I let him go .
(3) “No sooner (Hardly) + had + 主语 + 过去分词 + than(when) + 从句”。这两句的意思是……就……”、“刚……就……”。
Hardly had I sat down when the telephone rang .
(4) “Not only + 谓语第一部分 + 主语 + 谓语第二部分 + 其它 + but also + 并列句(可以是省略的) 。”
Not only was everything that he had taken away from him , but also his German citizenship .
(5) 虚拟语气中省略了“if”的条件句。其结构是：
“Were (Had或Should) + 主语 + 谓语第二部分 + …… + 主语”。
Had you worked harder , you would have passed the exam .
(6) as 引导的让步状语从句，其句型一般为“形容词(名语／动词) + as + 其它”。
Pretty as the is (= Though she is pretty) , she is not clever .
Child as he is , he knows a lot .
Try as he might , he would fail again .
3 . 作句型转换时的两点注意情况：
(1) 要分清两种倒装句 , 即全部倒装和部分倒装。
(2) 有的复合句是主句倒装，有的是从句倒装，要加以分清。如：Only after his mother came back was he able to go to school . (主句倒装)
Child as he is , he can solve the problem . (从句倒装)
