4、s ( 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

5、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 .

6、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

7、 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：Ill 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

8、拨quarrel with sb about / over sth因为向某人争吵3. dare与needdare 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

9、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 repaired2） I _ to ask the teachers for advice in the office . A . dare not B .

11、d 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

12、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1. have a seat = take a seat坐下Entering the hall , he had a seat in the corner .Have a seat
