1.【解析】 答案是B。這里or表示轉(zhuǎn)折，意為不然，否則。此句可以轉(zhuǎn)換為：If you drink too much coffee in the evening, you wont fall asleep. 2.【解析】答案是A。努力學(xué)習(xí)，你就會趕上別人的。此句可以轉(zhuǎn)換為：If you study hard, you will catch up with others. 注：祈使句在變?yōu)閕f從句后，原祈使句后的and或or必須去掉。 3.【解析】本題考查的是賓語從句引導(dǎo)詞的選擇。連詞that在賓語從句中無實(shí)際意義，口語中經(jīng)常省略掉。whom和what應(yīng)當(dāng)是充當(dāng)句子中的賓語，而此句中從句的賓語為 discussion, A,C均不適宜。這里是讓對方告訴明天在哪里開討論會，只有時(shí)間，沒有地點(diǎn)，所以此題的正確答案是D。 4.【解析】本題考查了賓語從句的語序及引導(dǎo)詞的選用。賓語從句要使用陳述句語序，即主語 + 謂語的結(jié)構(gòu)，因此首先排除C,D兩項(xiàng)；who和whose都可以引導(dǎo)賓語從句；根據(jù)句意誰的風(fēng)箏，故選B。 5.【解析】 答案是B。根據(jù)賓語從句時(shí)態(tài)前后應(yīng)保持一致的原則，首先應(yīng)排除A，C兩項(xiàng)；又根據(jù)賓語從句的語序要求陳述句結(jié)構(gòu)，排除D項(xiàng)。 6.【解析】 原句為陳述句，引號內(nèi)為直接引語，按要求應(yīng)改成由that引導(dǎo)的賓語從句。根據(jù)上面的表格，主句的時(shí)態(tài)是過去時(shí)，從句的謂語動詞要變成相應(yīng)的過去的時(shí)態(tài)，以保持前后時(shí)態(tài)的一致。本題答案是George said that he was writing a report and he couldnt go shopping with me. 7.【解析】 答案是A。原句Whats the matter with Peter?是一個(gè)特殊疑問句，變成了由what引導(dǎo)的賓語從句，因此what在句中作主語，the matter作表語，所以語序不變，系動詞is不可放到表語the matter之后。故仍應(yīng)是whats the matter。類似的結(jié)構(gòu)還有I dont know what is wrong with Peter.而不是I dont know what wrong is with Peter. 8.【解析】此題既考查了賓語從句的時(shí)態(tài)，又考查了條件狀語從句。第一個(gè)句子里if引導(dǎo)的是一個(gè)賓語從句，因不知是否要來，動作尚未發(fā)生，從句的謂語動詞應(yīng)用將來時(shí)will come才合情理。第二句中的if引導(dǎo)的是一個(gè)條件狀語從句，意思是如果他要來的話。在條件句中應(yīng)用一般現(xiàn)在時(shí)代替將來時(shí)。惟有D項(xiàng)才同時(shí)符合這兩個(gè)條件，所以答案為D。 9.【解析】 按照語法規(guī)則我們可以首先確定賓語從句為陳述句語序，便可以排除C、D選項(xiàng)。其次要弄清這里的could不表示過去時(shí)態(tài)，而是表示一種客氣、婉轉(zhuǎn)的語氣，所以賓語從句不用過去時(shí)態(tài)。本題的答案是B。 10.【解析】 當(dāng)賓語從句表示的是一個(gè)自然現(xiàn)象、科學(xué)原理、客觀事實(shí)時(shí)，即使主句是過去時(shí)，從句也要用一般現(xiàn)在時(shí)。因此本題答案為B。 11.【解析】賓語從句中如果是含有or的選擇疑問句，應(yīng)該用whether來連接，而不用if，這里應(yīng)填whether。注：whether和if均可用來引導(dǎo)賓語從句，意思也相同，一般可互換。但下列情形須用whether，不用if。 (1)介詞之后： We are talking about whether we will go for a picnic or not. (2)不定式之前： I asked her whether to sit at the front. (3)與or not連用時(shí)： I dont know whether he can speak Japanese or not. 12.【解析】 當(dāng)主句的主語為I，we，謂語為think，believe，guess，suppose等詞時(shí)，其后的賓語從句的否定應(yīng)該轉(zhuǎn)移到主句上。如：I dont think she can drive a bus.所以本題的答案為：I dont believe he can work out the problem by himself. 13.【解析】 答案是B。在when，as，before，after，as soon as，until等引導(dǎo)的時(shí)間狀語從句和if引導(dǎo)的條件狀語從句中，從句該用一般將來時(shí)的時(shí)候，需用一般現(xiàn)在時(shí)去代替一般將來時(shí)。這里的A，C，D三個(gè)選項(xiàng)均表示將來，所以不能選。 14.【解析】答案是A。因?yàn)閟ince引導(dǎo)的時(shí)間狀語從句在絕大多數(shù)情況下時(shí)間搭配比較 固定，主句是可延續(xù)性動詞的現(xiàn)在完成時(shí)，從句是瞬間性動詞的一般過去時(shí)，表示動作的起點(diǎn)。但是It is．．since句型例外；如:it is almost ten years since we left school. 1516【解析】結(jié)果狀語從句可以轉(zhuǎn)換成簡單句。當(dāng) that從句是否定式時(shí)，可轉(zhuǎn)換成tooto do結(jié)構(gòu)，當(dāng)that從句是肯定式時(shí)，可轉(zhuǎn)換成形容詞／副詞+enough( for sb ) to do結(jié)構(gòu)。上面兩道題的答案分別為15. too，to 16. enough，to 17.【解析】表示因?yàn)樗赃@種概念時(shí)，不可受漢語習(xí)慣的影響。要么只用 because，構(gòu)成原因狀語從句；要么只用SO，構(gòu)成并列句。because/as/since不能與so出現(xiàn)在同一句中。 18.【解析】 though/although不能與but出現(xiàn)在同一句中，但可以用yet。 In fact, I didnt understand the question ___was asked in French. A. who B.whose C.which D.what 19.【解析】答案是C。事實(shí)上我不懂用法語提出的這個(gè)問題。句中，先行詞question指物，故用關(guān)系代詞which，在定語從句中作主語。 20.【解析】答案是A。我們所需要的是淡水。句中that we need是定語從句，修飾先行詞all。 all是不定代詞，后面一般不用關(guān)系代詞which修飾，排除C。what不引導(dǎo)定語從句，排除B。D則與句意不符。 1.【解析】 答案是B。這里or表示轉(zhuǎn)折，意為不然，否則。此句可以轉(zhuǎn)換為：If you drink too much coffee in the evening, you wont fall asleep. 2.【解析】答案是A。努力學(xué)習(xí)，你就會趕上別人的。此句可以轉(zhuǎn)換為：If you study hard, you will catch up with others. 注：祈使句在變?yōu)閕f從句后，原祈使句后的and或or必須去掉。 3.【解析】本題考查的是賓語從句引導(dǎo)詞的選擇。連詞that在賓語從句中無實(shí)際意義，口語中經(jīng)常省略掉。whom和what應(yīng)當(dāng)是充當(dāng)句子中的賓語，而此句中從句的賓語為 discussion, A,C均不適宜。這里是讓對方告訴明天在哪里開討論會，只有時(shí)間，沒有地點(diǎn)，所以此題的正確答案是D。 4.【解析】本題考查了賓語從句的語序及引導(dǎo)詞的選用。賓語從句要使用陳述句語序，即主語 + 謂語的結(jié)構(gòu)，因此首先排除C,D兩項(xiàng)；who和whose都可以引導(dǎo)賓語從句；根據(jù)句意誰的風(fēng)箏，故選B。 5.【解析】 答案是B。根據(jù)賓語從句時(shí)態(tài)前后應(yīng)保持一致的原則，首先應(yīng)排除A，C兩項(xiàng)；又根據(jù)賓語從句的語序要求陳述句結(jié)構(gòu)，排除D項(xiàng)。 6.【解析】 原句為陳述句，引號內(nèi)為直接引語，按要求應(yīng)改成由that引導(dǎo)的賓語從句。根據(jù)上面的表格，主句的時(shí)態(tài)是過去時(shí)，從句的謂語動詞要變成相應(yīng)的過去的時(shí)態(tài)，以保持前后時(shí)態(tài)的一致。本題答案是George said that he was writing a report and he couldnt go shopping with me. 7.【解析】 答案是A。原句Whats the matter with Peter?是一個(gè)特殊疑問句，變成了由what引導(dǎo)的賓語從句，因此what在句中作主語，the matter作表語，所以語序不變，系動詞is不可放到表語the matter之后。故仍應(yīng)是whats the matter。類似的結(jié)構(gòu)還有I dont know what is wrong with Peter.而不是I dont know what wrong is with Peter. 8.【解析】此題既考查了賓語從句的時(shí)態(tài)，又考查了條件狀語從句。第一個(gè)句子里if引導(dǎo)的是一個(gè)賓語從句，因不知是否要來，動作尚未發(fā)生，從句的謂語動詞應(yīng)用將來時(shí)will come才合情理。第二句中的if引導(dǎo)的是一個(gè)條件狀語從句，意思是如果他要來的話。在條件句中應(yīng)用一般現(xiàn)在時(shí)代替將來時(shí)。惟有D項(xiàng)才同時(shí)符合這兩個(gè)條件，所以答案為D。 9.【解析】 按照語法規(guī)則我們可以首先確定賓語從句為陳述句語序，便可以排除C、D選項(xiàng)。其次要弄清這里的could不表示過去時(shí)態(tài)，而是表示一種客氣、婉轉(zhuǎn)的語氣，所以賓語從句不用過去時(shí)態(tài)。本題的答案是B。 10.【解析】 當(dāng)賓語從句表示的是一個(gè)自然現(xiàn)象、科學(xué)原理、客觀事實(shí)時(shí)，即使主句是過去時(shí)，從句也要用一般現(xiàn)在時(shí)。因此本題答案為B。 11.【解析】賓語從句中如果是含有or的選擇疑問句，應(yīng)該用whether來連接，而不用if，這里應(yīng)填whether。注：whether和if均可用來引導(dǎo)賓語從句，意思也相同，一般可互換。但下列情形須用whether，不用if。 (1)介詞之后： We are talking about whether we will go for a picnic or not.

1.【解析】 答案是B。這里or表示轉(zhuǎn)折，意為不然，否則。此句可以轉(zhuǎn)換為：If you drink too much coffee in the evening, you wont fall asleep. 2.【解析】答案是A。努力學(xué)習(xí)，你就會趕上別人的。此句可以轉(zhuǎn)換為：If you study hard, you will catch up with others. 注：祈使句在變?yōu)閕f從句后，原祈使句后的and或or必須去掉。 3.【解析】本題考查的是賓語從句引導(dǎo)詞的選擇。連詞that在賓語從句中無實(shí)際意義，口語中經(jīng)常省略掉。whom和what應(yīng)當(dāng)是充當(dāng)句子中的賓語，而此句中從句的賓語為 discussion, A,C均不適宜。這里是讓對方告訴明天在哪里開討論會，只有時(shí)間，沒有地點(diǎn)，所以此題的正確答案是D。 4.【解析】本題考查了賓語從句的語序及引導(dǎo)詞的選用。賓語從句要使用陳述句語序，即主語 + 謂語的結(jié)構(gòu)，因此首先排除C,D兩項(xiàng)；who和whose都可以引導(dǎo)賓語從句；根據(jù)句意誰的風(fēng)箏，故選B。 5.【解析】 答案是B。根據(jù)賓語從句時(shí)態(tài)前后應(yīng)保持一致的原則，首先應(yīng)排除A，C兩項(xiàng)；又根據(jù)賓語從句的語序要求陳述句結(jié)構(gòu)，排除D項(xiàng)。 6.【解析】 原句為陳述句，引號內(nèi)為直接引語，按要求應(yīng)改成由that引導(dǎo)的賓語從句。根據(jù)上面的表格，主句的時(shí)態(tài)是過去時(shí)，從句的謂語動詞要變成相應(yīng)的過去的時(shí)態(tài)，以保持前后時(shí)態(tài)的一致。本題答案是George said that he was writing a report and he couldnt go shopping with me. 7.【解析】 答案是A。原句Whats the matter with Peter?是一個(gè)特殊疑問句，變成了由what引導(dǎo)的賓語從句，因此what在句中作主語，the matter作表語，所以語序不變，系動詞is不可放到表語the matter之后。故仍應(yīng)是whats the matter。類似的結(jié)構(gòu)還有I dont know what is wrong with Peter.而不是I dont know what wrong is with Peter. 8.【解析】此題既考查了賓語從句的時(shí)態(tài)，又考查了條件狀語從句。第一個(gè)句子里if引導(dǎo)的是一個(gè)賓語從句，因不知是否要來，動作尚未發(fā)生，從句的謂語動詞應(yīng)用將來時(shí)will come才合情理。第二句中的if引導(dǎo)的是一個(gè)條件狀語從句，意思是如果他要來的話。在條件句中應(yīng)用一般現(xiàn)在時(shí)代替將來時(shí)。惟有D項(xiàng)才同時(shí)符合這兩個(gè)條件，所以答案為D。 9.【解析】 按照語法規(guī)則我們可以首先確定賓語從句為陳述句語序，便可以排除C、D選項(xiàng)。其次要弄清這里的could不表示過去時(shí)態(tài)，而是表示一種客氣、婉轉(zhuǎn)的語氣，所以賓語從句不用過去時(shí)態(tài)。本題的答案是B。 10.【解析】 當(dāng)賓語從句表示的是一個(gè)自然現(xiàn)象、科學(xué)原理、客觀事實(shí)時(shí)，即使主句是過去時(shí)，從句也要用一般現(xiàn)在時(shí)。因此本題答案為B。 11.【解析】賓語從句中如果是含有or的選擇疑問句，應(yīng)該用whether來連接，而不用if，這里應(yīng)填whether。注：whether和if均可用來引導(dǎo)賓語從句，意思也相同，一般可互換。但下列情形須用whether，不用if。 (1)介詞之后： We are talking about whether we will go for a picnic or not. (2)不定式之前： I asked her whether to sit at the front. (3)與or not連用時(shí)： I dont know whether he can speak Japanese or not. 12.【解析】 當(dāng)主句的主語為I，we，謂語為think，believe，guess，suppose等詞時(shí)，其后的賓語從句的否定應(yīng)該轉(zhuǎn)移到主句上。如：I dont think she can drive a bus.所以本題的答案為：I dont believe he can work out the problem by himself. 13.【解析】 答案是B。在when，as，before，after，as soon as，until等引導(dǎo)的時(shí)間狀語從句和if引導(dǎo)的條件狀語從句中，從句該用一般將來時(shí)的時(shí)候，需用一般現(xiàn)在時(shí)去代替一般將來時(shí)。這里的A，C，D三個(gè)選項(xiàng)均表示將來，所以不能選。 14.【解析】答案是A。因?yàn)閟ince引導(dǎo)的時(shí)間狀語從句在絕大多數(shù)情況下時(shí)間搭配比較 固定，主句是可延續(xù)性動詞的現(xiàn)在完成時(shí)，從句是瞬間性動詞的一般過去時(shí)，表示動作的起點(diǎn)。但是It is．．since句型例外；如:it is almost ten years since we left school. 1516【解析】結(jié)果狀語從句可以轉(zhuǎn)換成簡單句。當(dāng) that從句是否定式時(shí)，可轉(zhuǎn)換成tooto do結(jié)構(gòu)，當(dāng)that從句是肯定式時(shí)，可轉(zhuǎn)換成形容詞／副詞+enough( for sb ) to do結(jié)構(gòu)。上面兩道題的答案分別為15. too，to 16. enough，to 17.【解析】表示因?yàn)樗赃@種概念時(shí)，不可受漢語習(xí)慣的影響。要么只用 because，構(gòu)成原因狀語從句；要么只用SO，構(gòu)成并列句。because/as/since不能與so出現(xiàn)在同一句中。 18.【解析】 though/although不能與but出現(xiàn)在同一句中，但可以用yet。 In fact, I didnt understand the question ___was asked in French. A. who B.whose C.which D.what 19.【解析】答案是C。事實(shí)上我不懂用法語提出的這個(gè)問題。句中，先行詞question指物，故用關(guān)系代詞which，在定語從句中作主語。 20.【解析】答案是A。我們所需要的是淡水。句中that we need是定語從句，修飾先行詞all。 all是不定代詞，后面一般不用關(guān)系代詞which修飾，排除C。what不引導(dǎo)定語從句，排除B。D則與句意不符。 1.【解析】 答案是B。這里or表示轉(zhuǎn)折，意為不然，否則。此句可以轉(zhuǎn)換為：If you drink too much coffee in the evening, you wont fall asleep. 2.【解析】答案是A。努力學(xué)習(xí)，你就會趕上別人的。此句可以轉(zhuǎn)換為：If you study hard, you will catch up with others. 注：祈使句在變?yōu)閕f從句后，原祈使句后的and或or必須去掉。 3.【解析】本題考查的是賓語從句引導(dǎo)詞的選擇。連詞that在賓語從句中無實(shí)際意義，口語中經(jīng)常省略掉。whom和what應(yīng)當(dāng)是充當(dāng)句子中的賓語，而此句中從句的賓語為 discussion, A,C均不適宜。這里是讓對方告訴明天在哪里開討論會，只有時(shí)間，沒有地點(diǎn)，所以此題的正確答案是D。 4.【解析】本題考查了賓語從句的語序及引導(dǎo)詞的選用。賓語從句要使用陳述句語序，即主語 + 謂語的結(jié)構(gòu)，因此首先排除C,D兩項(xiàng)；who和whose都可以引導(dǎo)賓語從句；根據(jù)句意誰的風(fēng)箏，故選B。 5.【解析】 答案是B。根據(jù)賓語從句時(shí)態(tài)前后應(yīng)保持一致的原則，首先應(yīng)排除A，C兩項(xiàng)；又根據(jù)賓語從句的語序要求陳述句結(jié)構(gòu)，排除D項(xiàng)。 6.【解析】 原句為陳述句，引號內(nèi)為直接引語，按要求應(yīng)改成由that引導(dǎo)的賓語從句。根據(jù)上面的表格，主句的時(shí)態(tài)是過去時(shí)，從句的謂語動詞要變成相應(yīng)的過去的時(shí)態(tài)，以保持前后時(shí)態(tài)的一致。本題答案是George said that he was writing a report and he couldnt go shopping with me. 7.【解析】 答案是A。原句Whats the matter with Peter?是一個(gè)特殊疑問句，變成了由what引導(dǎo)的賓語從句，因此what在句中作主語，the matter作表語，所以語序不變，系動詞is不可放到表語the matter之后。故仍應(yīng)是whats the matter。類似的結(jié)構(gòu)還有I dont know what is wrong with Peter.而不是I dont know what wrong is with Peter. 8.【解析】此題既考查了賓語從句的時(shí)態(tài)，又考查了條件狀語從句。第一個(gè)句子里if引導(dǎo)的是一個(gè)賓語從句，因不知是否要來，動作尚未發(fā)生，從句的謂語動詞應(yīng)用將來時(shí)will come才合情理。第二句中的if引導(dǎo)的是一個(gè)條件狀語從句，意思是如果他要來的話。在條件句中應(yīng)用一般現(xiàn)在時(shí)代替將來時(shí)。惟有D項(xiàng)才同時(shí)符合這兩個(gè)條件，所以答案為D。 9.【解析】 按照語法規(guī)則我們可以首先確定賓語從句為陳述句語序，便可以排除C、D選項(xiàng)。其次要弄清這里的could不表示過去時(shí)態(tài)，而是表示一種客氣、婉轉(zhuǎn)的語氣，所以賓語從句不用過去時(shí)態(tài)。本題的答案是B。 10.【解析】 當(dāng)賓語從句表示的是一個(gè)自然現(xiàn)象、科學(xué)原理、客觀事實(shí)時(shí)，即使主句是過去時(shí)，從句也要用一般現(xiàn)在時(shí)。因此本題答案為B。 11.【解析】賓語從句中如果是含有or的選擇疑問句，應(yīng)該用whether來連接，而不用if，這里應(yīng)填whether。注：whether和if均可用來引導(dǎo)賓語從句，意思也相同，一般可互換。但下列情形須用whether，不用if。 (1)介詞之后： We are talking about whether we will go for a picnic or not.
