1．(P16)A healthy lifestyle is generally a balanced life in which yu make wise chices. 【翻译】健康的生活方式通常是一种平衡的生活，在其中你可以做出明智的选择。【句式剖析】本句中的which是一个关系代词。它和前面的介词in一起在句中引导一个定语从句，修饰前面的名词life，作后置定语。
【归纳拓展】使用“介词＋关系代词”引导定语从句时要注意以下几点：(1)在该结构中，关系代词通常用whm(先行词指人)，which(先行词指物)和whse(表所属关系)。
(2)该结构可以引导限制性定语从句，也可以引导非限制性定语从句。在限制性定语从句中，介词放在关系代词之前时，关系代词不能省略，但若介词后置，则可以用that/wh代替which/whm。(3)确定介词时要遵循“一先、二动、三意义”的原则。
(4)某些在从句中充当时间、地点、原因等状语的“介词＋关系代词”结构可以同关系副词 when, where, why等互换。This is the ring n which she spent 1,000 dllars. ＝This is the ring that/which she spent 1,000 dllars n. 这就是她花1 000美元买的戒指。
A friend is smene wh draws yu ut, with whm yu sparkle and becme mre knwledgeable. 朋友就是能使你畅所欲言的人，与他(她)在一起你就会精神焕发，更有见识。I cannt remember the age at which he wn the prize. (根据先行词的习惯搭配确定用介词at)我记不起他获奖时的年龄了。
She lves her husband greatly, withut whm she cannt rebuild her life. (根据从句的意义确定用介词withut)她深爱着她的丈夫，没有他，她不能重新开始生活。The hliday villa had large windws n every side frm which (＝where) ne culd enjy the lakeside scenery, as enchanting as fairyland. 度假别墅轩窗四围，满目湖光山色，真如仙境。
Ten years f hard wrk changed her greatly, fr which reasn he culd hardly recgnize her at first sight. (which作定语)十年的辛劳使她变化很大，因此他第一眼很难认出她来。
特别提醒：(1)指抽象或隐含关系时，介词要置于关系代词之前。The decisin was made at the meeting during which I kept falling asleep. (during不能后置)这项决定是在我昏昏入睡的那次会议上做出的。
(2)某些两个词或三个词构成的动词短语在定语从句中一般不宜将其介词置于关系代词前。This is the girl whm he will take care f. (f不宜前置)这就是他将照顾的女孩。

2．(P16)Neither t much nr t little is gd. 【翻译】太多太少都不好。【句式剖析】本句中的neither…nr…意为“既不……也不……”。
【归纳拓展】使用neither…nr时应注意如下几点：(1)连接句中两个相同的句子成分。(2)连接主语时，谓语动词遵循就近一致原则。(3)遵循就近一致原则的其他并列连词：either…r…不是……就是……nt nly…but als…不仅……而且……nt…but…不是……而是……
Nt the passengers but the driver was t blame. 不是乘客而是司机应该受到责备。Neither the father nr the children are interested in the film. 父亲和孩子们对这部电影都不感兴趣。Either yu r ne f yur students is t attend the meeting that is due tmrrw. 要么是你或者你的一名学生应该出席明天的会议。

3．(P16)Make small changes each day and yur lifestyle will becme healthier. 【翻译】每天做些小的改变，你的生活方式就会变得更健康。【句式剖析】本句的“make small changes each day”是一个祈使句，在句中相当于一个条件状语。
【归纳拓展】在“祈使句＋and/r＋陈述句”结构中要注意：(1)前后为承接关系时用and或then。(2)前后是相反关系时用r，therwise或r else。
(3)前面的祈使句可以改为if引导的条件状语从句，即：祈使句＋and＋陈述句＝If…，＋主句祈使句＋r/r else/therwise＋陈述句＝If…nt…＋主句(4)前面的祈使句部分除了是动词短语外，还可是名词，即：名词词组＋and＋陈述句Listen carefully，and yu’ll understand it. ＝If yu listen carefully, yu’ll understand it. 仔细听，你就会明白。
Give up smking, r/r else/therwise yu may die f lung cancer. 戒掉烟，否则你可能会死于癌症。It is really very dangerus. One mre step, and the baby will fall int the well. 真危险。再多迈一步，这个小孩儿就掉进井里了。
[针对练习]单句语法填空(1)Dn’t mve, ________ I’ll fire!(2) ________ (take) mre physical sprts, and yu will becme healthy. (3)Practise mre, ________ yu will becme mre skillful. 【答案】(1)r　(2)Take　(3)and
【例句观察】1．T see is t believe. 2．T finish s much hmewrk is nt easy fr me. 3．It is imprtant t listen t the teacher carefully in class.
【我的领悟】1．句1中的主语和表语都是 ________，其中的系动词is意为“是”。2．在句2中，用不定式作主语，其谓语部分是一个 ________ 结构。这类结构用于说明主语的特点或性质。3．在句3中的It是一个形式主语。句子真正的主语是 __________________ 。
Keys：1．不定式　2．系表结构3．t listen t the teacher carefully in class
本单元的重点语法项目就是不定式作主语。不定式短语作主语时，可以直接放在句首，但在很多情况下，尤其是在疑问句和感叹句中，往往放在谓语之后，而用代词it作形式主语。不定式作主语，通常出现在下面的这些结构中：
1．不定式＋is＋表语(名词或形容词)。这类结构中的is意为“是”。T stand ut amng s many players is nt easy. 在这么多选手中脱颖而出并不容易。T knw that we are ignrant is the first step t knwledge. 走向知识的第一步是要知道我们是无知的。
2．It is＋adj. (easy, imprtant, difficult…)＋不定式。在这类结构中，it是形式主语，真正的主语是后面的动词不定式。在这个结构中，不定式的前面可加“fr sb. ”构成不定式的复合结构。这类结构可改用不定式直接作主语。注意，如果形容词表示人的性格或品质(如flish, clever, wise, stupid等)时，则形容词后面的介词要用f。
It is difficult (fr us) t keep up friendship. ＝T keep up friendship is difficult fr us. 我们保持友谊是非常困难的。It is necessary fr yu t learn English well. ＝T learn English well is necessary fr yu. 你们学好英语是非常必要的。
It is flish f yu t say s. (注意，这类结构不可改用不定式直接作主语)你这样说真傻。
3．It is＋n. (a pity, a pleasure, ne’s duty, a shame)＋不定式。这个结构也可以改用不定式直接作主语。It is a shame t fail the exam. ＝T fail the exam is a shame. 考试不及格是很丢人的事情。It is a pleasure t wrk with yu. ＝T wrk with yu is a pleasure. 同你一起工作是一件令人快乐的事情。
4．It takes/needs/requires＋sme time (hurs, mnths, days, patience…)＋不定式。It wn’t take yu t lng t explain this prblem t me. ＝T explain this prblem t me wn’t take yu t lng. 给我解释一下这个问题用不了你多长的时间。It tk us three hurs t finish all the wrk. ＝T finish all the wrk tk us three hurs. 做完所有的工作花了我们三个小时的时间。
