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 .

www.deyou8.com 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
