And the word quickly got around that he was from New York City.For some reason he sat beside Mary. Mary felt __18__ (please), because there were many empty seats in the room. But she quickly realized that it wasn't her, it was probably the fact that she sat in __19__ last row.__20__ he thought he could escape attention by sitting at the back, he was wrong. It might have made it a little __21__ (hard) for everybody because it meant they had to turn around, but that didn't stop the kids in the class. Of course whenever they turned to look at him, they had to look at Mary, __22__ made her feel like a star.“Do you need those glasses for medical reasons？” the teacher asked.

Then he took __25__ off, gave a big smile and said, “That's cool.” Step 1：通读全文，掌握主旨大意。本文主要讲述的是Mary与新转来的学生在课堂上发生的一些趣事。Step 2：逐题解答，确定答案。16．wearing。 根据结构可知，此处考查非谓语动词，判断wear的逻辑主语。17．had_bought。 as if后面跟的虚拟语气，表示与过去事实相反的假设。18．pleased。felt为系动词，其后跟形容词，注意please的形容词形式。19．the。考查冠词用法。20．If。根据句式结构可知，此处考查连词，根据语义来判断此处填表示条件的连词if。21．harder。考查形容词的用法，a little用来修饰比较级，结合语境可知。22．which。此处考查定语从句，根据句子可知此处考查非限制性定语从句。which引导定语从句并在从句中作主语。23.for。根据空格位置可知此处应填介词，结合语义可知答案。24．what。考查名词性从句用法，根据wonder后跟从句可知，该从句为宾语从句，因此按宾语从句选择连词的方法确定答案。25．them。根据句子结构可判断考查代词用法，结合语义，判断代替的内容确定答案。Step 3：代入验证。需考虑语法结构正确且语义符合逻辑，语法结合语义才能确保万无一失。 知识清单(1)各种名词性从句的结构特点；(2)常用连接代词及连接副词的运用条件；(3)对于what/that/whatever/whether/if等易混名词性从句的掌握；(4)it在名词性从句中作形式主语和形式宾语的用法；(5)that的省略情况以及各从句的时态与语序问题。学情分析考生在学习从句的过程中存在着以下几点问题：(1)句子结构分析不清，对各种从句类型无法准确判断；(2)引导词在从句中的使用情况不熟练，也不能准确运用，例如what与which，what与whatever等；(3)名词性从句与定语从句中的引导词混用，比如关系代词that引导定语从句，在从句中作主语或宾语，而在名词性从句中that不作任何成分，只起连接作用；(4)对从句中的语序及时态意识淡漠，而造成一些不必要的错误。考点一　名词性从句的不同类型及其结构分析下列例句，归纳各名词性从句的结构。1主语从句①That you are coming to London is the best news I have heard this long time.长久以来我听到的最好的消息就是你要来伦敦。②What matters most in learning English is enough practice.学习英语最重要的是足够的训练。③It is none of your business what other people think about you.

And I feel sorry for ______ marries her.[解析]　whoever　考查宾语从句用法。根据句式结构可以判断此处考查的是宾语从句用法，且从句中缺少主语指人，结合句意可知答案是whoever。句意：——你真的很憎恨Mary吗？——是的，的确是，并且无论谁娶她我都为谁感到难过。2．从句中不缺少主语或宾语，而是缺少表语、状语等成分，此时则用when, where, why, how, whether/if, how many/much等带有语义的连接词。①Some students even have no idea of why they are studying, so they waste much time playing.(宾语从句，缺语义)一些学生甚至都不知道为什么学习，所以他们浪费很多时间玩儿。②It is obvious that people hold different opinions about whether voluntary services should be financially rewarded.(宾语从句，缺语义)很明显，人们对志愿者服务是否应该有经济奖励持不同观点。③What is concerning us greatly is when the workers held up in that area yesterday will be set free.

(主语从句，不缺成分和语义)会议推迟到了下周一已经定下来了。②He gave me a suggestion that we should practise speaking English in class. (同位语从句，不缺成分和语义)他建议我们课上练习说英语。[典例5]　[2015·福建泉州五校摸底]________ golf was first played in Scotland in the 15th century is generally agreed.[解析]　That　考查主语从句用法。根据句式结构可知，该题考查主语从句，且从句中既不缺成分也不缺语义，故填that。句意：人们公认高尔夫是在15世纪的苏格兰发源的。[典例6]　[2015·北京西城区期末]It is becoming a threat to the Chinese language and culture ________ some people can't write Chinese characters properly.[解析]　that　考查主语从句用法。根据句式结构可知考查主语从句用法，从句中既不缺语义也不缺成分，故填that。句意：一些中国人不会正确书写汉字成为中国语言和文化的一大威胁。考点三　whether与if的区别1．表语从句和同位语从句常用whether引导不用if；当主语从句放于句首时，也常用whether引导不用if；当it作形式主语，主语从句放在后面时用whether或if引导均可，但是如果被后置的主语从句中含有表选择意义的or时必须用whether。  ①Whether the meeting will be held is still a problem.(主语从句放于句首)＝The problem is whether the meeting will be held.(表语从句)＝I have no idea whether the meeting will be held.(同位语从句)是否要开会仍然是个问题。②It is doubtful whether/if he will come here.(主语从句放于句末)他是否要来这儿还令人怀疑。2．whether和if都可以引导宾语从句，表示“是否”，在口语或间接引语中两者可以互换使用，但在有些情况下，whether和if的用法有一定区别。(1)在及物动词后(×)I don't care whether he doesn't come.(whether从句中不能用否定式)(√)I don't care whether/if he comes or not.(√)I don't care whether or not he comes.(×)I don't care if or not he comes.(if不与or not直接连用)(√)I don't know whether to go there.(2)在介词后在介词后常用whether，不用if。It depends on whether you can do the work well.那取决于你是否能做好这项工作。[典例7]　[2015·四川雅安重点中学月考]What the doctors really doubt is ________ my mother will recover from the serious illness soon.[解析]　whether　考查表语从句的用法。根据句式结构可知，从句为表语从句，结合语义可知，答案是whether, 因表语从句中不能用if替换whether, 故只能填whether。句意：医生真正怀疑的是我的母亲是否能很快从重病中恢复过来。考点四　疑问词＋ever引导的名词性从句1．“疑问词＋ever”引导名词性从句时，有词义，并且在从句中充当一定的句子成分。①Whoever breaks the law should be punished.无论谁触犯法律都应该受到惩罚。②Wherever he goes makes his parents worry.他无论去哪儿他的父母都担心。2．“疑问词＋ever”还可以引导让步状语从句，这时可以和“no matter＋疑问词”互换。但“no matter＋疑问词”只能引导让步状语从句，不能用来引导名词性从句。Whatever(＝No matter what) you do,  you must do it well.无论你做什么，都必须做好。[典例8]　[2015·重庆一中一诊]To improve the quality of our products, we asked for suggestions ________ had used the products.[解析]　whoever　考查宾语从句。根据句式结构可以判断该题考查宾语从句，作“asked”的宾语，从句中无主语，结合句意可知答案是whoever。句意：为了改善产品质量，我们向所有使用过我们产品的顾客广征建议。 NO.1  解题步骤 1．分析空格的位置或句子结构，判断是否考查连词。2．根据从句的不同特点，确定考查的从句类型。3．根据不同从句连接词的特点，结合语义确定答案。 NO.2  解题技巧1．若两个句子(有两个主谓结构)之间，没有句号或分号，也没有连词，那空格处必定是填连词，否则，句子结构就不完整。2．根据两句之间的意义和逻辑关系，或者根据句式结构，确定是并列句还是某种主从复合句。3．一旦判断是名词性从句，就根据名词性从句中缺少什么句子成分来确定选用什么连词，若从句中缺少主语和宾语，用连接代词，若作状语就用连接副词；如果不缺少成分则要考虑意思是否完整，是否需要用whether/if；如果不缺少成分且意思完整则用that。[典例9]　[2015·东北三校模拟一]If I ask you ________ you love，the answers will most likely roll off your tongue(顺嘴说)．[解析]　what　分析句子结构可知需填连词，“ask”后为宾语从句，且从句中缺少宾语，指事，故填what。句意：如果我问你爱什么，答案很可能顺嘴说出来。[典例10]　[2015·吉林实验中学四模]He discussed his thoughts on innovation (创新) in China, Facebook's future in the country and ________ he is studying Chinese.[解析]　why　分析句子结构可知，“discuss”后面为宾语从句，但从句中不缺少主语和宾语，再结合语意可知，此处应填why。句意：他谈论了他在中国思想上的创新，Facebook的未来发展前景以及为什么学习汉语。  1．名词性从句主要侧重于连接词的选择，其解题步骤如下：(1)根据句型结构判断是否是名词性从句；(2)判断从句中的成分是否缺少主语或宾语，缺少主语或宾语选择连接代词what (ever), which (ever), who (ever)以及whom (ever)；(3)若从句中不缺少主语和宾语，则根据语义使用whether/if, when, where，why, how, how much/many等连接词；(4)若从句中既不缺少主语和宾语，亦语义完整，则用that。2．名词性从句中缺少主语/宾语时，常用的连接代词为what, 而定语从句中用关系代词that/which，注意区别开来。3．名词性从句中的连接词that只有在引导宾语从句时可以省略(且是第一个宾语从句)，其他从句中均不可省略。4．从句中的时态要和主句的时态保持一致，语序要用陈述句语序。5．名词性从句是主句中不可缺少的一部分，这也是名词性从句的特性，考生可根据此特性与其他从句进行区分。
