Ⅲ. 语法重点：

本单元复习过去分词作定语和状语的用法。过去分词可以作名词的前置定语，也可以作名词的后置定语。当过去分词作状语时，要注意其逻辑主语的问题。

另外要学习同源宾语的用法，如：( page 2 Unit 13 )

Einstein ( lived ) the rest of his ( life ) quietly in the USA . ( 爱因斯坦在美国静静地度过了余生 ) 。其中宾语 life 与 live 是同源的名词，即同源宾语 ( cognate object ) 。这是中学英语课本中十分常见的语法现象，这种宾语用在某些不及物动词之后，并往往有定语修饰，现举例如下：

1 . My grandmother lives a happy life in the countryside . 我的祖母在乡下过着幸福的生活。

2 . Premier Zhou Enlai fought a hard fight against “Gang of Four” . 周恩来总理与“四人帮”进行了一场艰苦的斗争。

3 . He breathed his last breath last night . 昨天夜里他咽了最后一口气。

4 . He laughed a hearty laugh at the good news . 听到好消息后他开心地笑了。

5 . Chris will sing us a pop song . 克莉斯将给我们唱首流行歌曲。

6 . Her son died a hero\'s death in the war . 她儿子在战争中英勇牺牲了。

7 . She sleeps a sweet sleep only on Sundays . 只有在周日她才能甜美地睡一觉。

8 . I dreamed a pleasant dream last night . 昨天夜里我做了个愉快的梦。

9 . My father signed a deep sign . 我父亲深深地叹了一口气。

10 . My mother smiled a happy smile when I passed the entrance examination .当我通过了入学考试时，我妈妈幸福地笑了。

【指点迷津】

单元重点词汇点拨

1. delay推迟;耽搁

What delayed you so long yesterday ?

The train was delayed one hour by the accident .

〖点拨〗without delay毫无耽搁地，立即。after a delay of two hours延迟两个小时以后。

注意：delay + -ing推迟干……。如：I’ll delay answering his letter until I feel like writing .

另外，put off + ing推迟干……。如：They put off holding the sports meet .

2. quarrel争吵;吵架

He had a quarrel with his wife about / over the housework .

〖点拨〗quarrel with sb about / over sth因为……向某人争吵

3. dare与need

dare 和 need 这两个词的用法有它们独特的地方。词性有两种而且不同的词性决定了它们不同的用法。对中学生来讲掌握它们的用法有一定的难度，无论教师从理论上如何解释，但同学们在具体运用中都会出现浮光掠影，若明若暗，零乱残缺，张冠李戴的现象。这两个词难就难在对词性的判断，它们可以作为情态动词用(其后不带 to)，又可以作为行为动词用(后面要带 to)。为了便于区分其词性和掌握用法，同学们可以采用下面的口诀帮助记忆。

〖点拨〗口诀：“dare , need 真奇怪，既行为(指行为动词)又情态(指情态动词)，是行为，把 to 带(指其后用不定式)，是情态，把 to “卖”(指其后去掉 to，只用动词原形)。若 need (=want ，require) 的主语是某物，愿与 -ing (=to be done)结姻缘。”

请做以下练习：

1) Something is wrong with my watch . It needs ____ .

A . to repair B . repairing C . repaired D . being repaired

2) I ____ to ask the teachers for advice in the office .

A . dare not B . not dare C . dare don\'t D . don\'t dare

3) He ____ come to school to give us a lecture on how to learn English .

A . need B . need to C . needs D . to need

4) She ____ do so .

A . won\'t dare B . dare not C . will dare to D . not dare

5) We ____ to think it over before we take action .

A . needing B . needs C . need D . needed

[答案与简析]1 — 5 BDABC 。第一题选B;某物作 need 的主语，后面应用动名词的主动形式表被动含义。第二题选D;dare 用作行为动词，其否定形式应为“助动词+ not dare to do sth . ”第三题选A;need 用作情态动词，其后跟动词原形。第四题选B;dare 用作情态动词，直接加 not 表示否定。第五题选C;need 用作行为动词，主语是人称代词，其后应该是 need to do sth .

4. furniture (总称) 家具

A lot of furniture will be bought for you .

〖点拨〗furniture是不可数名词，表示件数要用量词piece / set 。如：three pieces of furniture三件家具。

5. doubt怀疑;疑虑

I have no doubt that he will pass this examination .

〖点拨〗beyond doubt =out of doubt毫无疑问。

用于肯定句时用doubt if / whether …。用于否定句时用doubt that 。
