back,1.“,复合名词”变复数的几种形式,(1),由,man,和,woman,构成的复合名词变复数时，两个成分都要变。如：,a man doctor a woman driver,(2),由“名词,+,名词”以及“动名词,+,名词”构成的复合名词，把复数词尾放在一个名词上。如：,police officers,警官,flower shops,花店,frying pans,平底锅,(3),由“名词,+,副词”构成的复合名词，把复数词尾放在名词上。如：,passers-by,过路人,lookers-on,旁观者,(4),由“家庭成员,+in-law”,构成的复合名词，复数形式放在第一个成分上。如：,fathers-in-law,（岳父）,(5),复合名词中没有名词时，把复数词尾放在最后一个词上。如：,go-betweens,中间人，媒人,grown-ups,成年人,2.appear;seem;look,appear,seem,look,都有“看起来似,”,之意，但其暗含意思和用法又各有不同。,(1)appear,强调外表给人的印象，有时含实质上并非如此的意思，如：,He appears to know more than he really does,。,(2)seem,暗示有一定根据的判断，这种判断往往接近事实，如：,His health seems to be better.,(3)look,着重由视觉得出的印象，如：,He doesnt look his age.,3.,动词不定式的省略,为了避免重复，我们常常把作宾语、宾补和谓语动词的一部分的不定式省略，只保留动词不定式的符号,to,。,(1)How about coming to my house?,Id love to if it doesnt give you so much trouble.,在,hope,like,love,promise,want,wish,等词后作宾语的不定式常省略。,（,2,）,Dont close the window until I ask you to.,在,allow,ask,tell,等词后作宾语补足语的不定式常省略。,再如：,Dont touch the light unless your mother allows you to.,（,3,）,He didnt want to hand in his composition,but he had to.,在,be able to,be going to,have to,need to,enough to,used to,等后的不定式需省略。再如：,I dont sing much,now,but I used to a lot.,这三个以,work,为中心词的介词短语，在意思和用法上均不相同。,(1)at work,表示“在工作、在上班”，作表语或状语。例如：,They are both at work today.,今天他们俩都在上班。,(2)out of work,表示“失业”，是介词短语，相当于,lost ones job,或,be unemployed,。例如：,If you dont work hard,youll be out of work.,如果你不好好工作就会失业。,(3)after work,表示“下班后”，作时间状语。例如：,What do you usually do after work?,下班后你经常干什么,4.at work;out of work;after work,5.to ones surprise,表示“令人吃惊的是”，是介词短语。作结果状语或插入语，位于句首，其中,ones,指形容词性物主代词或名词所有格,To ones joy,To ones surprise,To ones disappointment,To ones anger,6.promise,sb,.to do,sth,.allow/permit,sb,.to do,sth,.,允许,/,答应某人做某事,My father promised me to give up smoking.,My father doesnt permit/allow me to smoke.,promise to do,sth,.,（后跟不定式）,allow/permit doing,sth,.,（后跟动名词）,7.lielied,lied,lying,lielaylainlying,laylaid,laid,laying,(1)lielied,lied,lying,意思是“说谎”。,Obviously he was lying.,(2)lielaylainlying,意思是：“躺、平放、卧”“位于”。,The look is lying on the desk.,(3)laylaid,laid,laying,意思是“放置”“产（卵）”“下（蛋）”，,lay,是原形动词。,The hen laid an egg yesterday.,注意：,lying,既是“说谎”的现在分词，又是“躺、位于”的现在分词。,lay,既是“放置、产卵”“下蛋”的原形动词，又是“躺、位于”的过去式。,8.case,用法小结,(1),名词,case,的词意,意为“情形、情况”。,If thats the case,youll have to work much harder.,意为“病例、案例”。,There were seven cases of cholera.,意为“箱、盒、容器”。,John bought a case of beer.,(2),由,case,构成的短语,in case,意为“因为可能发生某事、以防万一”，,是介词短语，,in that case,意为“既然那样、假若是那样的话”，,用来承接上文。,in any case,意为“无论如何、总之”。,in no case,意为“在任何情形下决不、无论如何都不”，,用于句首时句子要进行部分倒装。,in case of,sth,.,意为“若发生某事、如果、假如”，,是短语介词，后接名词、代词、,-,ing,形式作宾语,.,句型转换：,1.Although China is a big country,only 7%,of the land can be used for farming.,2.Speak
