二、學海導航
【 學法指要 】
單元句型思路明晰
1 . 表語從句的句型
That\'s what we did in China in the old days .那就是我們中國從前的作法。
［明晰］What we did China in the old days 是表語從句。表語從句在句中作表語，它位于主句的連系動詞之后。又如：
That\'s why she is so happy .
This is what we want .
The question is whether can finish our work by tomorrow evening .
2 . make + 賓語 + 動詞原形
It makes me feel thirsty . 它使我感到口渴。
［明晰］①make 在此句中是“使，迫使”之意。make sb . do sth . 是一種跟不帶 to 的不定式的結構，feel thirsty 就是不帶 to 的不定式，作句中賓語 me 的賓語補足語。
He made them fear him . 他使他們懼怕他。
②在被動語態(tài)中，make 后面的不定式帶 to . 如：
He was made to do it . 別人使他做的。
在主動語態(tài)的句子中，在 feel , hear , see , listen to , notice , watch , make , have , let 等動詞之后的賓補，不定式通常不帶 to。但是在被動語態(tài)的句子中，這些動詞后不定式要帶 to。例如：
主動語態(tài)：We heard him sing in the next room .
被動語態(tài)：Hw was heard to sing in the next room .
單元難點疑點釋疑
1 . What was it used for ? 它用來干什么的 ?
［釋疑］這是一般過去時的被動語態(tài)，助動詞 be 根據(jù)人稱的變化，變?yōu)?was 或 were。
I was called Xiao Mao at that time . 那時人們叫我小毛。
They were sent here by Uncle Wang yesterday .
他們是王大叔昨天送到這里來的。
2 . Can you tell me the way to the museum , please ? 請問你能告訴我去博物館的路嗎 ?
［釋疑］下面問路的方式很常見：
Where is the museum , please ? 請問博物館在哪里 ?
How can I get to the museum ? 我怎么去博物館呢 ?
Which is the way to the museum ? 哪條路是通向博物館的 ?
3 . Turn right at the second crossing . 在第二個十字路口處向右拐。
［釋疑］這句話也可說成 Take the second turning on the right .
4 . Go across the bridge . 穿過那座橋。
［釋疑］ ( 1 ) across 為介詞，“橫過，穿過”。cross 為動詞，“橫過，穿過”。crossing 為名詞，“十字路口；人行橫道；交叉點”。例如：
He can swim across the river . 他能游過河去。
He swims very well . He can cross the river . 他游泳游得很好，他能游過河。
Our school is on the corner of the crossing . 我們學校在十字路口的拐角處。
( 2 ) 辨異：介詞 across 強調的是“橫穿”，而介詞 through 則強調“從……中間穿過”。例如：
Go through the back door , and you\'ll find a beautiful garden there . 穿過后門，你就會看到那里有一個漂亮的花園。
5 . You can\'t miss it . 你不會看到它的。
［釋疑］ ( 1 ) miss 為動詞時意為：fail to hit , catch , find , meet , hear , see , etc . 即：沒打著，沒趕上，沒發(fā)現(xiàn)，沒遇見，沒聽見，沒看見等。例如：
He missed the ball . 他沒接著球。
Did you miss the early bus ? 你沒趕上早班車嗎 ?
I\'m sorry I missed you at the station . 很抱歉，我在車站沒見到你。
He never missed a day\'s work . 他從來沒停過一天工作。
( 2 ) miss 在口語中，還常常用作“惦記，想念”。例如：
We all miss you very much . 我們都想念你。
You don\'t know how I miss you . 你可不知道我是多么惦記你。
( 3 ) 表示沒做成什么事情時，要用 miss doing something 這一形式。例如：
I got up late this morning . I missed catching the train at 6 : 40 . 今天早晨起床遲了，沒能趕上 6：40 的那趟火車。
6 . Go up this road to the end . 沿著這條路一直到盡頭。
［釋疑］在看地圖時，有“上北下南”之說，句中的 up 即屬這種用法。
7 . Last week , a group of Class 3 students decided to go to the museum in the centre of the town . 上星期，三班的一組學習決定去參觀城鎮(zhèn)中心的博物館。
［釋疑］ ( 1 ) group 為名詞，意為“組，群，隊”。又如：
There are five students in their study group . 他們的學習小組有5位學生。
Look ! Groups of children are playing on the ground . 瞧，三五成群的孩子在操場上玩耍。
( 2 ) decide to do sth . “決定干某事”。例如：

8 . They saw many old things on show in glass - topped tables . 他們觀看了玻璃桌面的桌子里展覽的許多古老的東西。
［釋疑］ ( 1 ) on show “展覽，陳列”。例如：
The pictures on show are drawn by her . 展出的圖畫都是她畫的。
My handwriting will be on show next week . 我的書法將于個個星期展出。
What\'s on show tonight ? ( 根據(jù)具體情景，可譯為 ) 今晚上演什么電影 ? 或：今晚有什么 ( 電視 ) 節(jié)目 ?
( 2 ) 介詞短語作定語時，放在它所修飾的名詞后面，如不只一個介詞短語，語序與漢語的相反。所以，句中的 on show 須放在 in glass - topped tables 前面。例如：
Can you see the cat under the table in corner ? 你看見墻角桌子下面的那只貓嗎 ?
The woman with a baby on her back is Li Ming\'s mother .
9 . Some of the things were hundreds of years old . 其中一些物品距今已有幾百年的時間了。
［釋疑］hundreds of…“數(shù)百……”，其中 hundreds 是名詞復數(shù)，例如：hundreds of children 幾百個孩子， hundreds of flowers 好幾百種花
注意：one hundred , two hundred , three hundred 中的 hundred 是數(shù)詞，不可加 s。
10 . She pointed at one of the things . 她指著其中一件物品。
［釋疑］在這里 point 為動詞，“指，指向”。例如：

( 2 ) 賓語從句前由于有逗號斷開，連接記號 that 不可省略。

［釋疑］ ( 1 ) surprise 作動詞用，指“使人驚奇，使人意外”。例如：
What he said surprised us . 他講的話使我們感到驚訝。
Did the bad news surprise her ? 這壞消息使她感到意外嗎 ?
( 2 ) surprised 作形容詞用，說明主語的狀態(tài)，意為“驚訝的”。例如：

They were all surprised to hear that . 聽到那件事，他們都覺得奇怪。
13 . Isn\'t it beautiful ! 它不美麗嗎 ? ( 它真美麗 ! )
［釋疑］用否定疑問句表示驚嘆，標點符號用感嘆號。
14 . It was used for keeping tea hot after it was made . 那是在茶泡好后用來保溫的。
［釋疑］ ( 1 ) keeping tea hot 中的形容詞 hot 作賓語 tea 的賓語補足語。例如：
Please keep your eyes closed . 請一直把雙眼閉著。

( 2 ) make tea “沏茶，泡茶”。又如：
But in England we still make tea in teapots . 然而在英國，我們仍然在茶壺里泡茶。
15 . That\'s what we did in China in the old days . 那就是中國在古老的時候，我們所采用的沏茶方法。
［釋疑］ ( 1 ) what we did in China in the old days 是表語從句。
( 2 ) what we did 字面含義“我們所做的”。這里用來指課文前面提到的把小茶壺放在另一個大罐子里保溫的方法。
16 . It makes me feel thirsty . 它使我感到口渴。
［釋疑］feel thirsty 是不帶 to 的動詞不定式，在句中作賓語 me 的補足語。
17 . The group of girls all moved on and had a good drink of tea together , from a modern thermos ! 這一群女生都繼續(xù)往前走去，從現(xiàn)代的保溫瓶里倒了茶，一起痛痛快快地喝了個夠。

They worked on there though it was raining heavily . 雖然當時下著大雨，他們仍在那里干活。
He walked on and on . At last he got out of the forest . 他走啊走啊，最后走出了樹林。
( 2 ) have a drink of tea “喝茶”

18 . When was the party founded ? 中國共產黨是什么時候成立的 ?
［釋疑］句中的 Party 第一個字母大寫，指的是中國共產黨，英文全稱為：the Chinese Communist Party 或 the Communist Party of China .
19 . It was founded on July 1 , 1921 . 他是1921年7月1日成立的。
［釋疑］ ( 1 ) 表示在幾月幾號時，要用介詞 on，如果只有表示在哪個月，則用介詞 in。例如：in January 在元月
( 2 ) July 1 的正式寫法為 July lst . 讀作 July the first .
20 . You can see these signs in a museum . 在博物館里，你能夠看到這些標志。
［釋疑］sign “標志，符號”。例如：
Dark cloud is a sign of rain . 烏去是下雨的跡象。

21 . Where else can you see them ? 你還能在別的地方看見它們嗎 ?
［釋疑］ ( 1 ) else 為副詞，“別的”其他的”。放在疑問副詞或疑問代詞后。又如：

Who else will go there with me ? 還有誰將和我一起去那里 ?
( 2 ) else 還經常放在不定代詞后使用，
22 . Look up the new words in a dictionary . 在詞典里查這些生詞。
［釋疑］ ( 1 ) look up 在此作“查閱”，注意不可說 look a dictionary .
( 2 ) 當 look up 的賓語為代詞時，必須把代詞放在 up 之前。
23 . 相似詞 find 與 found 的區(qū)別
［釋疑］find ( 找到，發(fā)現(xiàn) ) ，過去式和過去分詞為 found , found .
found ( 成立，建立 ) ，過去式和過去分詞為 founded , founded .

He founded a hospital in the town . 他在城里創(chuàng)辦了一所醫(yī)院。
24 . 行為動詞 do 的用法
［釋疑］①do 通常意謂“工作”或“從事某項活動”，當我們說起某項工作或活動，而又不確指某項活動時，常用 do 來表達。如：
Do something ! 做點什么吧 !
— What are you doing ? 你在干什么 ?
— I\'m reading . 我在讀書。 ( 即：That\'s what I\'m doing . )
— What did you do this morning ? 你今天上午做了什么事 ?
— I wrote some letters . 我寫了幾封信。 ( 即：That\'s what I did . )
— What have you done ? 你干了什么事呀 ?
— I\'ve broken this glass . 我把這玻璃杯打碎了。 ( 即：That\'s what I\'ve done . )
②意謂“做”的 do，常與 some / any / no 連用。如：
Haven\'t you got anything to do ? 你有什么事可干嗎 ?
I\'ve got nothing to do . 我沒事可干。
I\'m not going to do any work . 我將什么工作也不做。
③可用 do 來避免重復前面已用過的動詞。
Mary works 16 hours a day . I don\'t know how she does it . 瑪麗每天工作16小時，我不知道她是怎樣工作的。
That the dog for a walk . — I\'ve already done it .
你帶狗去散散步。 — 我已經這樣做了。
在簡略答語中，可用 do 避免重復問句中的動詞。如：
— Does he also study English ?
— Yes , he does . / No , he does not .
④動名詞前的 do , do + 動名詞可表示指明的工作。如：
do ( some ) shopping 買東西 / do the washing 洗衣服， do ( a lot of ) swimming ( 常 ) 游泳 / do some reading 讀點書
⑤do 和 make 的比較：
make 常用來表達“制造或創(chuàng)造”，do 表示從事某一活動，但含義不明確。試比較：
— What are you doing ? 你在做什么 ?
— I\'m making a cake . 我在做蛋糕。
— What are you making ? 你在制做什么 ?
— A cake . 蛋糕。
do 和 make 都有各種固定的組合，例如：
do the homework 做功課 / do the housework 做家務 / do the cooking 烹調 / do shopping 購物/ do one\'s best 盡力而為 / do someone a favour 幫某人的忙/ do good ( harm ) to sb . 對某人有好 ( 壞 ) 處。/ be made of 用…制造 / be made from 由…制造/ make a face 扮鬼臉 / make fun of 嘲笑/ make money 賺錢 / make progress 前進，進步/ make ready to 準備好 / make the best of 充分利用/ make up one\'s mind 下決心 / make use of 利用

【 心中有數(shù) 】
單元語法發(fā)散思維
一般過去時被動語態(tài)：
構成：主語 + was ( were ) + 及物動詞的過去分詞。
陳述句 ( Statements ) : The letter was written a week ago . 這封信是一星期前寫的。
疑問句 ( Questions ) : Was the letter written a week ago ? / When was the letter written ? 例句：
The museum was built two years ago . 這個博物館是兩年前建成的。
Was the thief caught by a policeman ? 這個小偷是被警察抓住的嗎 ?
Where were the children found ? 孩子們是在哪被發(fā)現(xiàn)的 ?
When was the watch bought ? 這塊手表是什么時候買的 ?
The thermos were used for keeping water hot . 這些暖水瓶是用于保存熱水的。
主動語態(tài)變被動語態(tài)的四個步驟：
①把主動語態(tài)句子中的賓語變成被動語態(tài)句子的主動。
②把主動語態(tài)句子中的謂語變成被動語態(tài)：be + 動詞的過去分詞。注意被動語態(tài)中 be 的時態(tài)與主動語態(tài)句子中的謂語動詞的時態(tài)相同。
③把主動語態(tài)中的主語變?yōu)?by 的賓語 ( 如為代詞，主格形式變成賓語形式 ) 。如果動作執(zhí)行者不需要強調或說明，by 短語可以省略。
Everybody likes Tom . 大家都喜歡湯姆。
Tom is liked by everybody . 湯姆被大家喜歡。
He wrote a letter . 他寫了一封信。
A letter was written by him . 這信是他寫的。
They are building a road . 他們正在修一條路。
A rood is being built ( by them ) . 那條路在修建中。
含有兩個賓語的主動結構變?yōu)楸粍咏Y構
主語結構中若有兩上賓語 ( 直接賓語和間接賓語 ) ，通常將表示人的間接賓語變?yōu)楸粍討B(tài)主語，而直接賓語 ( 表示物的 ) 作為保留賓語而不動。有時也可將直接賓語變?yōu)楸粍诱Z態(tài)主語，間接賓語作為保留賓語而不動，但其前通常要加介詞 to 或 for。如：
He gave me some books . 他給了我一些書。 ( 主動語態(tài) )
I was given some books . ( 間接賓語作主語 ) ( 較常見 )
Some books were given to me . ( 直接賓語作主語 )
Father bought me a pen . 父親給我買了支鋼筆。
I was bought a pen . ( 間接賓語作主語 )
A pen was bought for me . ( 直接賓語作主語 )
含有復合賓語的主動結構變?yōu)楸粍咏Y構
