Ⅲ. 语法学习
学习疑问词的直接引语和间接引语的9个关键点。
【指点迷津】
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须是 worth 的主语。如：
This film is worth seeing it . (错)
This film is worth being seen . (错)
This film is worth seeing . (正)
That picture is worth looking at . (正)
(3) 接 while 或 one\s 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须是完整的非谓语动词短语作主语。如：
It 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”，“可尊敬的”、“相配的”等，可作表语也可作定语，作表语时其后也必须有连带成份。
(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 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〗注意，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 (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. jewellery = jewelery（总称）珠宝
She has a lot of jewellery .
〖点拨〗jewellery是不可数名词，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毕竟，到底；别忘了（该词组用语提醒对方或者表示转折）
Don’t 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 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拜访某人。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 doctor’s on the way to work .
另外，call on sb to do是“号召某人干……”。
5. bring out取出
I’d like you to bring them out .
6. try on试穿。但try out检验。
Never buy shoes without trying them on first .
7. have a very good time过得十分愉快
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 , don’t forget to pay them back to him recently .
12. at most = at the most至多；充其量
The job will be finished in ten days at the most .
注意其反义词组是：at least = at the least
13. match A and / with B“把A和B配合”
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 one’s mind to / on sth = set one’s 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……祝福
They drink to each other’s health and wish each other good luck .
Let’s drink to your success .
注意：“为……的健康干杯”也可以用drink sb’s health
二、学海导航
【学法指要】
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，如果先行词指的是“人”，通常要用 who。例如：
Tom is the very man who I\m going to employ .
This watch is the same one that I\m 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 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，第二个 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。
