32、ll .A real eco-travel should 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. 第一處：a→an。考查冠詞。eco-travel的讀音以元音音素開頭，所以用an。 第二處：appreciate→appreciated?？疾闀r態(tài)。根據(jù)時間狀語Last weekend可知，應用一般過去時。 第三處：

33、so→but?？疾檫B詞。一路上我們欣賞美麗的景色，但是有人摘花。前后表示轉折關系，故用but。 第四處：rubbishes→rubbish。考查名詞。rubbish作“垃圾”講，為不可數(shù)名詞。 第五處：truly→true?？疾樾稳菰~。此處應用形容詞修飾名詞eco-travel。 第六處：刪除well后的as?？疾楣潭ū磉_。as well as后跟賓語，意為“以及”，不符合語境，此處應用as well表示“也”，放在句末。 第七處：like前加be。考查系動詞。此處like是介詞，should后缺少be動詞。 第八處：cleaner→clean?？疾樾稳菰~。根據(jù)and后面的green

34、以及語境可知，此處應用形容詞原級。 第九處：Enjoyed→Enjoying?？疾榉侵^語動詞。主語we和enjoy之間是主謂關系，所以應用現(xiàn)在分詞。 第十處：their→our?？疾榇~。主語是we，此處表示“我們應該盡我們最大的努力去保護大自然”，故應用our。 As time went by，I was made smaller. 隨著時間的推移，我被做得更小了。 as意為“隨著”，引導時間狀語從句。 as作為連詞的用法主要有： (1)“正如；按照”，引導方式狀語從句； (2)“當……時候；一邊……一邊；隨著”，引導時間狀語從句； (3)“因為；既然”，引導原

35、因狀語從句； (4)“盡管”，引導讓步狀語從句(從句使用部分倒裝，即將形容詞、副詞、名詞、動詞等放于as前面；單數(shù)可數(shù)名詞提前時應該省掉冠詞)； (5)引導比較狀語從句，常用于as...as...句型，意為“像……一樣……”(第一個as是副詞，第二個as是連詞)。 ①As autumn draws (draw) near，leaves begin to fall from the trees. 隨著秋天的臨近，樹葉開始凋落。 ②As you were (be) out，I left a message. 你不在，所以我留了一張字條。 ③Tired (Tire) as he was

36、，he worked on. 盡管他很累，他還繼續(xù)工作。 ④單句語法填空(2017·江蘇卷)A rethink is required—and as a new approach starts to become apparent, two ideas stand out. 　as/with as “隨著”，是連詞，引導時間狀語從句 with “隨著”，是介詞，后接名詞或代詞等構成with短語或with復合結構 ⑤As time went (go) on/by(＝With time going (go) on/by)，Einstein’s theory proved to be

37、 correct. 隨著歲月的推移，愛因斯坦的理論被證明是正確的。 And my memory became so_large_that even I couldn’t believe it! 我的存儲量變得如此之大，連我自己都不能相信！ so/such...that引導結果狀語從句，意為“如此……以至于”。 (1)so...that...基本句式： (2)such...that...基本句式： (3)so＋adj./adv.＋that...句型中，若結果狀語從句是否定形式，可以轉換成“too...to...”結構；若結果狀語從句是肯定形式，可以轉換成“...enough

38、 to...”結構。 (4)so that既引導結果狀語從句也引導目的狀語從句。引導目的狀語從句時常有can/could/may/might等情態(tài)動詞，此時so that可用in order that代替。 (5)當so/such及其后部分放在句首時，主句用部分倒裝。 ①She is so clever a girl that we all like her. ＝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 g

39、irl is she that we all like her. 她是一個如此聰明的姑娘，我們都喜歡她。 ②There was so little water left that only little children were given some. 剩下的水不多了，只給小孩分了一些。 ③It is such lovely weather that we all want to go out for a walk. 天氣那么好，我們都想出去散步。 【閱讀理解】 Grey clouds move as low as smoke over the treetops at Lolo
