30、 like this：take nothing away but your good memory；leave nothing behind but all water and green trees. the beauty of nature，we should try best to protect it.第一处：aan。考查冠词。ecotravel的读音以元音音素开头，所以用an。第二处：appreciateappreciated。考查时态。根据时间状语Last weekend可知，应用一般过去时。第三处：sobut。考查连词。一路上我们欣赏美丽的景色，但是有人摘花。前后表示转折关系，故

31、用but。第四处：rubbishesrubbish。考查名词。rubbish作“垃圾”讲，为不可数名词。第五处：trulytrue。考查形容词。此处应用形容词修饰名词ecotravel。第六处：删除well后的as。考查固定表达。as well as后跟宾语，意为“以及”，不符合语境，此处应用as well表示“也”，放在句末。第七处：like前加be。考查系动词。此处like是介词，should后缺少be动词。第八处：cleanerclean。考查形容词。根据and后面的green以及语境可知，此处应用形容词原级。第九处：EnjoyedEnjoying。考查非谓语动词。主语we和enjoy之

32、间是主谓关系，所以应用现在分词。第十处：theirour。考查代词。主语是we，此处表示“我们应该尽我们最大的努力去保护大自然”，故应用our。As time went by，I was made smaller.随着时间的推移，我被做得更小了。as意为“随着”，引导时间状语从句。as作为连词的用法主要有：(1)“正如；按照”，引导方式状语从句；(2)“当时候；一边一边；随着”，引导时间状语从句；(3)“因为；既然”，引导原因状语从句；(4)“尽管”，引导让步状语从句(从句使用部分倒装，即将形容词、副词、名词、动词等放于as前面；单数可数名词提前时应该省掉冠词)；(5)引导比较状语从句，常用于

33、as.as.句型，意为“像一样”(第一个as是副词，第二个as是连词)。As autumn draws (draw) near，leaves begin to fall from the trees.随着秋天的临近，树叶开始凋落。As you were (be) out，I left a message.你不在，所以我留了一张字条。Tired (Tire) as he was，he worked on.尽管他很累，他还继续工作。单句语法填空(2017江苏卷)A rethink is requiredand as a new approach starts to become apparent,

34、 two ideas stand out.as/withas“随着”，是连词，引导时间状语从句with“随着”，是介词，后接名词或代词等构成with短语或with复合结构As time went (go) on/by(With time going (go) on/by)，Einsteins theory proved to be correct.随着岁月的推移，爱因斯坦的理论被证明是正确的。And my memory became so_large_that even I couldnt believe it!我的存储量变得如此之大，连我自己都不能相信！so/such.that引导结果状语从

35、句，意为“如此以至于”。(1)so.that.基本句式：(2)such.that.基本句式：(3)soadj./adv.that.句型中，若结果状语从句是否定形式，可以转换成“too.to.”结构；若结果状语从句是肯定形式，可以转换成“.enough to.”结构。(4)so that既引导结果状语从句也引导目的状语从句。引导目的状语从句时常有can/could/may/might等情态动词，此时so that可用in order that代替。(5)当so/such及其后部分放在句首时，主句用部分倒装。She is so clever a girl that we all like her.

36、She is such a clever girl that we all like her.So clever a girl is she that we all like her.Such a clever girl is she that we all like her.她是一个如此聪明的姑娘，我们都喜欢她。There was so little water left that only little children were given some.剩下的水不多了，只给小孩分了一些。It is such lovely weather that we all want to go out
