1.These bad habits,if left unchecked,culd lead t mre serius nes when they becme adults. 这些坏习惯,如果放任不管,长大后可能会导致更严重的后果。
【句式分析】本句是复合句。if left unchecked 是条件状语从句的省 略,if 后面省略了they are。 状语从句的省略(1)可以省略成分的状语从句:时间、条件、让步、方式状语从句等。(2)状语从句省略成分的条件:从句主语与主句主语一致,或从句主语是 it;从句谓语含有 be,包括系动词 be、进行时态的be 或被动语态的 be。( 3)常见的连词有:when,while,nce,befre,till/until,whenever; if,unless;thugh/althugh;as,as if 等。
状语从句省略成分后的常见类型:连词+ 现在分词 / 过去分词 / 介词短语/ 形容词。If invlved in this case,yu will be punished. 如果卷入这件事,你将受到惩罚。(省略yu are)If necessary,yu can chse me t make the presentatin. 如果有必 要的话,你可以选择我来做这个报告。(省略it is)以下为约定俗成的省略形式:
if s 如果是这样的话 if nt 如果不是这样;否则if ever 如果曾经有的话 if any 如果有的话if/when necessary 如果有必要的话/ 在必要的时if/when pssible 如果可能的话/ 在可能的时候
(1)Thugh (anny) at Tm’s wrds,she frced a smile. (2)There are sme health prblems that,when nt (treat) in time,can becme bigger nes later n. (3)Harriet Stwe,mther f six,wrte parts f Uncle Tm’s Cabin while _______ (ck). (4)If (accept)fr the jb,yu’ll be infrmed sn. (5)I’m interested in the music club and I’d like t jin it pssible. 完成句子(6) (如果可能), I will learn t carve. (7) (必要的时候),I will step ut f my cmfrt zne.
Harriet Stwe 与ck 之间是主动关系,故用现在分词。while cking 补充完整为while she was cking。句意:哈里特• 斯托是六个孩子的母亲,她在做饭时写下了《汤姆叔叔的小屋》的部分内容。
If pssible
When necessary

(2)常用短语 t sum up 总而言之 t be brief 简言之t tell the truth 说实话 t be exact 确切地说t cnclude 总而言之,最后t be frank 坦白地说t begin/start with 首先t be hnest 说老实话坦白说,你的理论太抽象,学生们理解不了。T be frank,yur thery is t abstract fr the students t understand.
