语法 省略（Ellipsis）
一. 概念。 省略句是英语的一种习惯用法。按照语法的分析，句子应该具备的成分，有时出于修辞上的需要，在句中并不出现，这种句子叫做省略句（elliptical sentences，这种语法现象称为“省略”（ellipsis r leaving wrds ut。其特点是：虽然省去句子语法构造所需要的组成部分，但仍能表达其完整的意义。二. 类别。1. 为避免重复而进行的省略，状语从句的主语与主句的主语一致，并列结构中前后重复。2. 语法上的省略，如表示时间、距离概念时介词，单位的省略。3. 习惯用法上的省略，口语中居多。三. 重难点突破。
一. 简单句成分的省略
1. 省略主语。如: ( I ) Haven't seen yu fr ages! 2. 省略谓语。如： (Is there) Anything yu want? (Des) Anybdy need help? 3. 省略宾语。如： D yu knw where he is nw? I dn't knw (where he is ). 4. 省略主语和谓语（或谓语的一部分），只剩下表语、宾语、状语或其它成分。如： (I'm) Afraid I can't cme. (Have yu) Gt any ink?
1. 在含有状语从句的复合句中 , 主从句的主语相同，从句部分变化，若从句的主句是it或与主句的主语相同，且在谓语中含有be时，常省略从句的主语和be。例如： eg. We may try again when (it is) necessary . eg. When (she was) asked , she didn’t answer a wrd. 2. 在含有定语从句的复合句中，作宾语的关系代词that，which, whm可以省略；在以the same... as和such... as引导的定语从句中，可以省略与主句相同的部分；the way后面的定语从句中，可以省略that，in which。 例如： eg. All (that) yu ever want t d is ging shpping. 你所想的就是购物。 3. 在含有宾语从句的复合句中省略。如果宾语从句中的谓语部分与主句的谓语部分或上文的谓语部分相同，可将从句部分的谓语省略。eg. We will d what we can (d) t help yu.
在并列句中,如果后面的分句,与前面的分句有相同的部分,这一部分则常被省略掉,以免重复。如: 1. He teaches English and his brther maths. 2. We have been waiting fr her t cme back t see us, but (we have been waiting) in vain. 3. Jhn wn the first race and Jimmy the secnd.4. Cral is nt a plant but a variety f animal life.
1. S+助动词/情态动词+主语句型。这一结构用来表示相同概念，即前面所说的情况也同样适用于另一人或物，意思是“同样”、“也那样”，常理解为倒装结构。 eg. My rm gets very cld at night. S des mine. 2. 由nr，neither等引导的连续否定的句子也是一种省略句，这种句子在意思上与前面的句子是相同的，而且主谓用倒装。 eg. If Je' s wife wn' t g t the party, neither will he. 3. 不定式的省略 。 eg. The students want t enter the lab, but the mnitr advises them nt t (enter the lab).
1. One mre hur I’ll get the wrk finished.2. He has made a lt f films, but gd nes.3. The pliceman (stand) at the crssrad directs traffic every ther day. 4. The research is s designed that nce (begin) nthing can be dne t change it.5. The flwers his friend gave him will die unless (water) every day.6. The man stpped frm time t time as if (find) whether he was being fllwed. 7. If yu g t the West Lake in Hangzhu, yu'll find it mre attractive than cmmnly (suppse).
单元重点句型
◆ 教材原句 What were the highest and lwest temperatures recrded where yu live? •【句式分析】“where yu live” 是由where引导的 ___________________，表示 _________________ •【句型拓展】地点状语从句表示地点、 方位， 这类从句通常由where、wherever等引导。地点状语从句可置于句首、句中或句尾。地点状语从句与定语从句的区别：在于分句在句中作什么成分。作状语，则是状语从句;作定语修饰名词，则是定语从句where引导定语从句时，从句前应有一个表示地点的名词作先行词;而状语从句前则无需先行词。
”地点状语从句”
1. __________ there is a will, there is a way.2. Keep the keys t drs _________ yu can see them. 3. N matter ________ yu nw are in writing, yu can imprve with practice. 4. 你从何处来到何处去。(汉译英) 5. Fill in the blanks with the given phrases. Change the frm where it is necessary. (英译汉)
G back where yu came frm.
用所给的短语填空，必要的地方可以改变其形式。
◆ 教材原句 Nw we have anther chance t lk up at the stars, their beauty inspiring and giving us cnfidence t mve n. •【句式分析】语境中 “their beautify inspiring and giving us cnfidence t mve n.”该结构为 ____________________，属于_________________________动词自身带不同的逻辑主语，从而构成复合结构的形式作状语。其中，非谓语动词构成主动关系用现在分词，被动用过去分词。在本结构中, 名词beauty与动词inspire和give 构成 ______________ ，故分别用 ___________________________.•【句型拓展】独立主格结构由两部分组成，前一部分是名词或代词，后一部分是非谓语动词(不定式、现在分词、过去分词)或形容词、副词、名词或介词短语。前后两部分具有逻辑主谓关系，没有连词连接。独立主格结构本身不是句子，在句子中作状语，表时间、原因、条件、伴随、目的及状态等。
inspiring and giving
理解应用
1. Her wrk _______(d) she sat dwn fr a cup f tea.2. There _________ (be)n taxis, we had t walk.3. Weather ______________(permit), they will g n an uting t the beach tmrrw.4.

As an imprtant lecture _______________ tmrrw, the prfessr has t stay up late int the night.6. ___________ a wrd mre spken, she left the meeting rm.
will be given
单元重点句型
◆ 教材原句 Bur mm said that whatever happens, we shuld always try t see the gd side f things. •【句式分析】“whatever happens” 是由连词whatever引导的 _________ 从句，意为“无论发生什么事”，这时whatever 用 ________________________ 替换。•【句型拓展】“n matter+疑问词”结构只能引导让步状语从句，这时可以和“疑问词+ever”互换。 而“疑问词+ever”还可以引导名词性从句。
“n matter+疑问词”
1. When yu are faced with emergency, take ___________ measures yu cnsider best.2. ___________ breaks the new law, he r she will be punished .3. _____________ f yu cmes in first will receive a prize.4.
