高一英語教案非限制性定語從句
一、非限制性定語從句與限制性定語從句的區別 限制性定語從句,顧名思義,是對先行詞從本質或特征上進行限制的一種定語從句,它所修飾的詞代表一個(些)或一類特定的人或事、物。例如: a man who doesn’t want to learn from others can’t achieve much. 一個不向別人學習的人是不能指望有多大成就的。 a man被限定后,指一類特定的人。 限制性定語從句是不能去掉的,否則剩下的部分就失去意義而不能成立。非限制性定語從句則不然,它只對所修飾的詞作進一步的說明,去掉之后并不影響整個句子的含義。在形式上,非限制性定語從句與主句之間通常必須有逗號隔開。例如: finally we visited the giant yangtze gorges dam, which is the greatest key water control project in the world at present. 最后我們參觀了長江三峽大壩,它是目前世界上最大的水利樞紐工程。 本句若去掉定語從句,主句部分的含義仍然完整。歷年的高考題中,非限制性定語從句是出現頻率最高的考點之一,因此值得我們注意。 二、引導非限制性定語從句的which可以指代前面的先行詞,也可以指代前面整個句子。例如: that peter will marry alice, which has not been announced yet, has spread around. 彼特要娶愛麗斯這件事還沒宣布,卻已被傳得沸沸揚揚。 句子中的which指代“彼特要娶愛麗斯”這件事。 三、除which外,還可用when, where, who,whom等關系副詞或關系代詞引導非限制性定語從句。例如: after graduation, i decided to stay in chongqing, where i spent my childhood and four years of college life. 畢業后,我決定留在重慶,在那里我度過了我的童年和四年大學生活。 albert einstein left germany for the united states during world war ii, when jews were badly treated in germany. 第二次世界大戰期間,愛因斯坦離開德國去了美國,那時猶太人在德國受到極大的歧視。 注意:that不能引導非限制性定語從句。 四、在限制性定語從句中,如果先行詞作賓語時,引導詞可以省略;但引導非限制性定語從句的引導詞不能省,同時關系代詞whom不能用who替換。試比較: the american journalist (whom / who) the announcer mentioned in the news broadcast is said to have been killed by the gangsters. 播音員在新聞廣播中提到的那位美國記者據說已經被匪徒殺害了。 he was eager to go to the hospital to see his stepmother, whom he loved and respected as his own mother. 他急于想去醫院看望他的繼母,他像對親生母親一樣愛戴和尊敬她。 鞏固性練習: 從a、b、c、d中,選出可以填入空白處的最佳選項。 1. she heard the terrible noise, _____ brought her heart into her mouth. a. it b. which c. this d. that 2. dorothy was always speaking highly of her role in the play, ____, of course, made the others unhappy. a. who b. which c. this d. what 3. the weather turned out to be very good,____ was more than we could expect. a. what b. which c. that d. it 4. recently i bought an ancient chinese vase,____ was very reasonable. a. which price b. the price of which c. its price d. the price of whose 5. the youngest nurse has worked for 30 days in the sars hospital, ____ she spent her 19th birthday. a. that b. which c. where d. and (答案bbbc)
