高考英語總復(fù)習(xí) 語法專項 專題9 名詞性從句課件 新人教版.ppt

一,二,一、選擇合適的連接詞 名詞性從句就是具有名詞作用的從句。它在句中可以作主語、賓語、表語和同位語。解決有關(guān)名詞性從句的問題的關(guān)鍵是:通過從句的位置,辨別從句的類型;分析從句,看看從句中所缺少的句子成分和句意,最終確定選用合適的連接詞。 通過下面幾個句子,看看從句的類型: 1.That our team had won the match made us excited.(位于謂語之前,主語從句) 2.The headmaster said that our team had won the match.(位于謂語之后,賓語從句) 3.The fact was that our team had won the match.(位于系動詞之后,表語從句) 4.The headmaster announced the news that our team had won the match.(位于名詞之后,同位語從句),一,二,一,二,一,二,一,二,一,二,二、名詞性從句的幾個特殊情況 1.it用作形式主語的常見句型為: (1)It +be +形容詞(obvious,true,natural,surprising,good,wonderful,possible,likely,certain,probable,etc.)+ that. (2)It + be +名詞詞組(no wonder,an honour,a good thing,a pity,no surprise,etc.) + that. (3)It +be +過去分詞(said,reported,thought,expected,decided,announced,suggested,etc.) + that. (4)It + seems/appears/happens 等不及物動詞及短語+ that. (5)It doesnt matter ( makes no differences,etc.) + 連接代詞或連接副詞引導(dǎo)的主語從句,一,二,It makes no difference where we shall have the meeting. It is a pity (that) we havent contacted for ages. 很遺憾,我們幾年沒聯(lián)系了。 It has not been decided where the meeting is to be held. 在哪里開會還沒決定。 It doesnt matter whether she will come or not. 她是否來這無關(guān)緊要。,一,二,2.it用作形式賓語 如果賓語從句后還有賓語補足語,則必須用it作形式賓語,而將賓語從句后置,并且that不能省略。句型結(jié)構(gòu)為: (1)make/find/feel/consider/think it+ adj./n.(賓語補足語)+that. (2)like/dislike/love/hate/appreciate+it+if/when. I think it best that you should stay here. 我認(rèn)為你最好住這兒。 He hasnt made it known when he is going to get married. 他還沒宣布他何時結(jié)婚。 I hate it when people laugh at the disabled. 我討厭別人嘲笑我的殘疾。,一,二,3.動詞 doubt后接賓語從句時,通常要用 whether (if) 來引導(dǎo),而不用 that,因為 doubt 表示“懷疑”,其意不肯定、不明確;但是如果它用于否定式,其后的賓語從句則通常用 that 來引導(dǎo),因為 not doubt 表示“不懷疑”,其意是肯定的、明確的。 I doubt if/whether hell come. 我拿不準(zhǔn)他是否會來。 I dont doubt that he will succeed. 我敢肯定他會成功。 Do you doubt that he will win? 你不相信他會贏嗎?,一,二,4.be sure后的名詞性從句通常用that引導(dǎo),而 be not sure 后的名詞性從句則通常用whether/if 來引導(dǎo): Im sure that he is honest. 我肯定他是誠實的。 Im not sure whether/if he is honest. 我不敢肯定他是否誠實。 5.介詞后一般不接that引導(dǎo)的賓語從句,但介詞except及in除外。 His report is correct except that some details are omitted. 除了有些細(xì)節(jié)未提到之外,他的報道是正確的。 Criticism and self-criticism is necessary in that it helps us to correct our mistakes. 批評和自我批評是必要的,因為它能幫助我們改正錯誤。,一,二,6.否定轉(zhuǎn)移 在賓語從句中,主句的謂語動詞(詞組)是think、believe、suppose、imagine、consider、expect、guess、be sure等,且主句的主語是第一人稱并為一般現(xiàn)在時,對賓語從句的否定一般轉(zhuǎn)移到主句上,表示說話者提出一種委婉的看法或主張。 I dont believe Ive met you before. 我認(rèn)為我沒有見過你。 I dont think you will be late.我認(rèn)為你不會遲到。,.完成句子(高考真題變式訓(xùn)練) 1.The best moment for the football star was he scored the winning goal. 2.Some people believe has happened before or is happening now will repeat itself in the future. 3.Exactly the potato was introduced into Europe is uncertain,but it was probably around 1565. 4.Pick yourself up.Courage is doing youre afraid to do. 5.As John Lennon once said,life is happens to you while you are busy making other plans.,when,whatever,when,what,what,6. the delayed flight will take off depends much on the weather. 7.Grandma pointed to the hospital and said,“Thats I was born.” 8.Is it true that Mike refused an offer from Yale University yesterday?
