The air seemed thin as though its

19、 combination of gases had little oxygen left.空氣似乎很稀薄，好像在混合的氣體中剩下的氧氣很少?！酒饰觥?1）本句是由方式狀語從句構(gòu)成的復(fù)合句。2）as though引導(dǎo)方式狀語從句，as though/if“好像；似乎”，如： The animal was walking as though it had hurt its leg.這動(dòng)物走路的樣子好像傷了腿似的。3）The air seemed thin是主句。主句是系表結(jié)構(gòu)：seem是連系動(dòng)詞，thin是形容詞在句子中充當(dāng)表語。【拓展】 as though/if作連詞用時(shí)，通常用虛擬語氣，表示與

20、事實(shí)不符或相反的情況。如果表示與現(xiàn)在事實(shí)相反，謂語用did或were，如與過去事實(shí)相反，則用過去完成時(shí)。還可用真實(shí)語氣。如：The pen as though (if) is mine.這枝鋼筆好像是我的。2. If you cover something with a little of that liquid it will go soft.如果你把這種液體抹在某個(gè)東西上一點(diǎn)，它就會(huì)軟化【剖析】 1）本句是由條件狀語從句構(gòu)成的復(fù)合句。2）if引導(dǎo)的是條件狀語從句，通常用一般現(xiàn)在時(shí)表將來。如：She will play the piano only if she is paid.只有付給她報(bào)

21、酬，她才愿意演奏鋼琴。3）“It will go soft.”是主句，本句是系表結(jié)構(gòu)，go是連系動(dòng)詞，soft是形容詞作表語?！就卣埂?go作連系動(dòng)詞，意為“變得（如何）”，后接形容詞作表語，表示情況的變化并非人們所期望的。如:He has gone mad.他瘋了。3. The mu-mu drink is a strange mixture of carrot juice and cocoa，while the Dimpods drink lemonade mixed with herbs.這是一種胡蘿卜汁加可可粉的奇妙混合液，而丁潑茲喝的是含有香草的檸檬水。【剖析】 1）整個(gè)句子是由兩個(gè)

22、分句構(gòu)成的并列句，while是并列連詞。2）第一個(gè)分句是簡單的主系表結(jié)構(gòu)；第二個(gè)分句是主謂賓結(jié)構(gòu)。3）在第一個(gè)分句中“of carrot juice and cocoa”是mixture的后置定語；第二個(gè)分句中過去分詞短語“mixed with herbs”是lemonade的后置定語。【拓展】 1）while作為并列連詞時(shí)，意為“而，然而，但是”，往往表示前后兩個(gè)分句的對(duì)比。2）while作連詞，意為“的時(shí)候”時(shí)，從句謂語要用延續(xù)性動(dòng)詞。3）while作連詞，意為“雖然”時(shí)，其用法與although相同。4. The Dimpods have so many arms and legs th

23、at you cannot tell which is which.丁潑茲長著許許多多的手臂和腿，以至于你很難分清哪些是手臂哪些是腿。【剖析】 1）整個(gè)句子是由“so.that.”引導(dǎo)的復(fù)合句。2）“The Dimpods have(so）many arms and legs”是主句，“（that）you cannot tell which is which”是結(jié)果狀語從句。3）that在本句中被省略。一般來說，that在口語中有時(shí)會(huì)被省略，書面語中不省略為宜。【拓展】 結(jié)果狀語從句常由“so.that”或“such.that”引導(dǎo)，掌握這兩個(gè)句型，首先要了解so 和 such與其后的詞的搭配

24、規(guī)律。1）比較：so和 suchsuch 是形容詞，修飾名詞或名詞詞組；so 是副詞，只能修飾形容詞或副詞。如：so nice a flowersuch a nice flower2）so 還可與表示數(shù)量的形容詞如many, few, much, little等連用，形成固定搭配。如：so many/few flowersso much/little money3）so.that與such.that之間的轉(zhuǎn)換實(shí)際上就是 so與such之間的轉(zhuǎn)換。如：The boy is so young that he cant go to school.=He is such a young boy tha

25、t he cant go to school.這個(gè)男孩太小了，以至于不能上學(xué)。語法·剖析本單元的主要語法項(xiàng)目是過去分詞作狀語和定語。 一、過去分詞過去分詞有兩大特點(diǎn)：一是表被動(dòng)的概念；二是表動(dòng)作已完成。過去分詞在句中可用作定語、表語、賓語補(bǔ)足語或狀語等成分。過去分詞在句中作某種成分時(shí)，其邏輯主語一般為該分詞所表示的動(dòng)作的承受者。二、過去分詞作狀語的用法過去分詞或過去分詞短語常用于以下幾種狀語：分類說明舉例時(shí)間狀語可用于時(shí)間狀語從句，也可在過去分詞前加上連詞“when，while，until”等，使其時(shí)間意義更明確。1）Seen from the hill，the park looks

26、 very beautiful.=When it is seen from the hill，the parks are very beautiful.從山上看，這個(gè)公園非常美麗。2）Dont speak until spoken to.=Dont speak until you are spoken to.當(dāng)別人和你講話時(shí)，你才能講話。原因狀語可用于原因狀語從句或并列結(jié)構(gòu)。Touched by his teachers words，the boy cried.=The boy was touched by his teachers words,so he cried.這個(gè)男孩被老師的話打動(dòng)了

27、，所以他哭了。條件狀語可加連詞if，unless等轉(zhuǎn)換成條件狀語從句。Given more time，we could do it much better.（=If we were given more time，we could do it much better.）多給我們點(diǎn)時(shí)間，我們會(huì)做得更好。讓步狀語有時(shí)可加although，though，even if，even though，whether.or等連詞轉(zhuǎn)換成讓步狀語從句。Though warned of the storm，the farmers were still working in the fields.=Though th

28、ey had been warned of the storm, the farmers were still working in the fields.雖然農(nóng)民們已被告知將有風(fēng)暴，但他們?nèi)匀辉诘乩锔苫睢７绞桨殡S狀語加and可轉(zhuǎn)換成并列結(jié)構(gòu)從句。The teacher entered the classroom，followed by a group of his students.=The teacher entered the classroom and he was followed by a group of his students.老師走進(jìn)教室，后面跟著一群學(xué)生。三、學(xué)習(xí)過去分詞

29、作定語時(shí)，注意過去分詞所在的位置單獨(dú)的過去分詞作定語常常置于其所修飾的名詞前You should improve your spoken English.過去分詞短語作定語常常置于其所修飾的名詞后He is a teacher respectedby all his students.不及物動(dòng)詞的過去分詞作定語當(dāng)與其所修飾的名詞構(gòu)成邏輯上的動(dòng)賓關(guān)系時(shí)，必須在該動(dòng)詞后使用必要的介詞He is the student laughed at by all people just now.Unit 3   Life in the future一、請根據(jù)各句上下文的意義，選擇正確的單
