1.These bad habits，if left unchecked，culd lead t mre serius nes when they becme adults. （教材原句p.14） 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/ 在必要的时候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）［词汇复现］ 　　 　　　　 　　 　　（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.（课本P16）Simply speaking, a healthy lifestyle is abut finding the right balance and making gd chices.（1）一些不定式短语可用作独立成分，通常位于句首，有时位于句中或句末，要用逗号同其他句子成分隔开。说实话，我不喜欢这部影片中的那个有天赋的女演员。T tell the truth，I dn’t like the gifted actress in the mvie. （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.
完成句子（1） 　　　　　 　　　（总而言之），mst f the cmmittee members supprted the idea but a few were against it. （2） 　　　　　（简言之），he was happy with the result. （3）She wrte， 　　　　　（确切地说），ten nvels in her lifetime.（4） 　　　　　　　　（首先），he’s t yung fr that kind f jb. （5） 　　　　　 （说老实话），I dn’t really want t g t the party tnight.
T sum up/T cnclude
T be brief
t be exact
T begin/start with
T be hnest
3.疑问词 + 不定式该结构的句法功能：主语、宾语和表语Hw t reduce the ftprint f carbn is very crucial.如何降低碳的排放量是极其重要的。（作主语）The questin is when t vercme the infectius virus.问题是何时开始攻克这种传染性病毒。（作表语）I knw where t find that patritic yung man. 我知道到哪里去找那个爱国的年轻人。（作宾语)【学法点拨】 “ 疑问词+不定式”结构相当于一个由疑问词引导的名词性从句。 A judge must decide whse prf t believe. = A judge must decide whse prf he/she shuld believe. 法官必须决定相信谁的证据。
单句语法填空（1）I culdn’t decide 　　　　 　 bike t buy. （2）Twenty students want t attend the class that aims t teach hw 　　　　 　（read） fast. （3）When and where 　　　　 　（celebrate）his success hasn’t been decided. 完成句子（4） 　　　　　　　　（何时搞清楚） the prblem hasn’t been decided. （5）They didn’t decide 　 　　　　 　　（在哪里举行） the debate. （6）The questin is 　　 　　　　 　　 　（怎样拆卸） the machine.
