I think Ill wear it . . 语法学习学习疑问词的干脆引语和间接引语的9个关键点。单元重点词汇点拨1. worth 和 worthy 都是形容词，词义基本相同，“值得的”，但用法及搭配上却不相同。点拨 worth “值得的”、“值得的”，只能作表语，但不能单独作表语，其后必有
8、连带成份才能成立。如：This book is worth . (错) This book is worth reading . (正)(1) 其后接钱数或相当于代价的名词。如：The necklace was worth 100 francs at most .What / How much is it worth ?It is worth much .(2) 带及物动词的动名词的主动一般形式，若是不及物动词需加适当介词，但均表示被动意思，或者说所用动名词或动名词短语的逻辑宾语必需是 worth 的主语。如：This film is worth seeing it . (错)This fil
9、m is worth being seen . (错)This film is worth seeing . (正)That picture is worth looking at . (正)(3) 接 while 或 ones while 一起作表语。如：Going / To go there is worth while .(4) 句型：It is worth while doing / to do . sth . 此句型中，it 为形式主语代替动名词或不定式短语 doing / to do sth . 与(2)中的动名词不同，此时的动名词或不定式必需是完整的非谓语动词短语作主语。如：It
10、 is worth while discussing / to discuss the question .It is worth while looking at / to look at that picture .点拨worthy “值得的”，“高尚的”，“可敬重的”、“相配的”等，可作表语也可作定语，作表语时其后也必需有连带成份。(1) 加介词 of 短语。of 后可接名词(一般不接表示钱的名词)、代词和动名词的被动式。如：The watch was worthy of the chain .He is worthy of his work .This museum is worthy
11、 of a visit .This novel is worthy of being remembered .(2) 接不定式的被动式。This question is worthy to be discussed .(3) 放名词前作定语，worth 不能。如：Bethune is a worthy man .点拨留意，汉语中说“很值得时”只能用 well worth / worthy 不能用其他副词。如：This report is well worth listening to .Her behaviour is well worthy of great praise .2. steal
12、 (stole , stolen) 偷When a thief was stealing corn , a passer-by caught him by the hand .点拨steal sth from + sb (或者地点) 是“从偷”。但是，rob sb of sth抢劫某人。3. description描述Please give me a brief / full description of the accident .点拨beyond description无法形容，难以描述。如：The lady was beautiful beyond description .4. jew
13、ellery = jewelery（总称）珠宝She has a lot of jewellery .点拨jewellery是不行数名词，可以借助piece来表达可数的概念。如：Some of my jewelry is missing .单元词组思维运用1. after all终归，究竟；别忘了（该词组用语提示对方或者表示转折）Dont be so hard on him . After all , he is only six years old .I thought he would be against my plan , but he did his best to carry it
14、 out after all .2. all these years这么多年3. this once就这么一回；仅此一次4. call on sb探望某人。call at +地点是“去某地看看”。如：So I called on you and asked if I could borrow some jewellery .She always called at the doctors on the way to work .另外，call on sb to do是“号召某人干”。5. bring out取出Id like you to bring them out .6. try on试穿
15、。但try out检验。Never buy shoes without trying them on first .7. have a very good time过得非常开心8. without luck真倒霉9. be exactly like丝毫不差地像10. day and night = night and day夜以继日地11. pay back偿还；还钱If you lent money from him , dont forget to pay them back to him recently .12. at most = at the most至多；充其量The job w
16、ill be finished in ten days at the most .留意其反义词组是：at least = at the least13. match A and / with B“把A和B协作”Does this tie match with my suit ?14. invite sb to + 地点“邀请某人去”15. the Lost and Found失物招领处16. describe sth to sb向某人讲讲17. the entrance to / of 通向的入口18. live a hard life过着艰难的日子19. set ones mind to /
17、 on sth = set ones heart to / on sth一心扑在Nothing in the world is difficult if you set your mind to it .20. look back over / on回顾；回想过去。look forward to + 名词或者动名词“渴望”。21. from house to house挨家挨户He went from house to house to pay New Year calls .22. drink to为干杯；为祝愿They drink to each others health and wis
18、h each other good luck .Lets drink to your success .留意：“为的健康干杯”也可以用drink sbs health二、学海导航单元难点疑点思路明晰 1 . I was the only person in my office who was invited . 我是我的办公室里唯一的一个受邀请的人。 明晰当先行词前有 the only , the very , all , every , any , on 等修饰时，引导定语从句的关系代词只能用 that ( 这是相对 which 而言的 ) ，它在从句中作主语或宾语。但是，假如先行词指的是“
19、人”，通常要用 who。例如： Tom is the very man who Im going to employ . This watch is the same one that Im looking for . 2 . You tried it on and it looked wonderful on you . 你戴上项链试了试，它戴在你身上好看极了。 明晰 ( 1 ) try on 意为“试穿 ( 衣服、鞋等 ) ；试戴 ( 帽子、手套、首饰等 ) ”，on 为副词，若代词作其宾语，需置于 try 和 on 之间，如本句中的 tried it on。例如： Please try
20、on this pair of new shoes and see whether they fit you or not . Here is a skirt . Try it on , Mary . ( 2 ) 该句中的两个 on 都有“穿、戴”之意，但是，第一个 on 是副词，其次个 on 是介词，其后要跟宾语。又如： The foolish King had nothing on that day . She had a beautiful hat on her head . 3 . It cost us thirty - six thousand francs . 它 ( 那条项链 ) 花了我们三万六千法郎。
