一、教法建议
【抛砖引玉】
单元双基学习目标
Ⅰ. 四会单词和词组：have a seat , quarrel , long before , dare , upon , fasten , gun , again and again , blow (n .) , hall
三会单词和词组：personal , affair , relative , delay , pillow , nail , chest , pay … a visit , furniture , armchair , pet , doubt , silence , in silence , living room , strike , scream , snake , tiny , nephew , niece , connect to
Ⅱ. 交际英语：
1. I’m afraid I have to go now .
2. It is time sb + 动词的过去式
3. I hope you have a good journey back to …
4. It was nice to meet you .
5. Please remember me to sb请代我向……问好
6. I called to tell you that …
7. I’d like you to meet …
8. Thanks again for calling .
9. It is very kind of you to do …
10. I have to see to . 我必须处理 。
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 。
单元词组思维运用

注意：have a seat用于直接引语。

注意：It wasn’t long before是一个常用句型，意为“不久”。before long不久以后

注意：表示状态的“在……参观；在……访问”用on a visit to 。如：These singers have been on a visit to Africa for a month .

二、学海导航
【学法指要】
单元难点疑点思路明晰
1. I/ve got some personal affairs that I have to see to . 我有些私事非处理不可。
〖明晰〗1) affair, business 作“事物”讲时，这两个词的意义很相近，常可通用。
Mind your own affairs (business) . 少管闲事。
business不能用复数，而affair特别是指重大或头绪较多的事务时，常需要复数，在下面的句子里，这两个词不能通用。
Each Ministry of Foreign Affairs lodged a protest with the other . 双方外交部向对方外交部提出抗议。
Business before pleasure . 先办正事，再谈娱乐。
2)see to有“注意，照料，保证，修理，诊治”等意思。例如：
Your shoes need seeing to . 你的鞋得修补了。
You ought to have your eyes seen to by a doctor . 你应该请医生治眼睛。
2. I dare say my uncle will . I have no other relatives . 我认为我叔父会得到这笔钱，我没
