1、名词性从句中连词选择“三步法”在高考单项选择中，名词性从句中连词的选择往往是测试的热点。考生若不认真分析，没有一定的方法，常常造成判断上的失误，最终错选了连词。笔者认为，如果考生能采取“一分二划三看”三步法对试题加以分析，则会收到良效。一、 “一分”即分清从句类型：四种从句 主语从句（从句位于动词前作主语）宾语从句（从句位于动词后作宾语）表语从句（从句位于系动词之后作表语）同位语从句（从句位于特殊的名词如 idea,fact,news 等后补充说明前面的名词）二、 “二划”即划分出从句（用括号表示从句）（1）(That the erath is round) is true.（主语从句） v（
2、2）Do you know（where he lives）?（宾语从句）v（3）My opinion is (that you should not go alone) .（表语从句） v（4）I dont like the idea (that money is everything).（同位语从句） n三、 “三看”即看从句句意是否完整：1、句意不完整缺连接代词 人 who,whoever（主语）whom,whomever（宾语）物 what,whatever（主语、宾语）which,whichever（主语、宾语）2、句意完整（1）缺连接副词 ： 时间：when；地点：where,whe
3、rever；原因：why ；方式：how。（2）缺不作成份的连词 有含义：if 、wherther（是否） ；无含义：that注：if 一般不用来引导主语从句；that 只有在宾语从句中才可以省略。下面，我们以 4 道高考试题为例加以解析1、 he said at the meeting astonished everybody present.（NMET 93,19）A、What B、That C、The fact D、The matter析：（1）分清从句类型：因为主句动词 astonished 前有一个从句，则一定是主语从句。（2）划出主语从句：（ he said at the meet
4、ing）astonished everybodyvpresent.（3）看主语从句句意是否完整：从句动词 said 后缺宾语，即句意不完整，则一定缺连接代词。在四个选项中只有 What 可以做 said 的宾语，所以答案（A）正确。2、A computer can only do you have instructed it to do.（NMET 2001，31）A、how B、after C、what D、when 析：（1）分清从句类型：主句动词 do 后有一个从句，所以是宾语从句。（2）划分出宾语从句： do ( you have instructed it to do.) v（3）看
5、宾语从句句意是否完整：不定式 to do 后缺宾语，句意不完整，应缺少连接代词，所以只有答案（C）正确。3、I drove to Zhuhai for the air show last week.Is that you had a few days off?（NMET 99）A、why B、when C、what D、where 析：（1）分清从句类型：从句“ you had a few days off”位于“is ”之后，所以应该是表语从句。（2）划分出表语从句：Is that（ you had a few days off）? v（3）看表语从句句意是否完整：从译文“你请了几天假”可以
6、判断句意完整，应该缺连接副词或不作成份的连词。根据上下文含义，应该选择表示“原因”的“why” ，所以最佳答案为（A ） 。4、Information has been put forword more middle school graduates will be admitted into universities.（2001 年上海试题）A、while B、that C、when D、as析： （ 1）分清从句类型：根据句子结构分析“more middle school graduates will be admitted into universities.”应该修饰名词“Inform
7、ation”，所以是同位语从句。（2）划出同位语从句：Information has been put forword （ more nmiddle school graduates will be admitted into universities).（3）看同位语从句句意是否完整：根据从句含义“更多的中学生将被大学录取”可以判断，从句句意完整，所以可能缺连接副词或不作成份的连词。 （A） 、 （D）答案不是名词从句中的连词，根据句子的含义，应选一个不作成份的连词，故最佳答案为（B） 。请同学们根据“三步法” ，试作以下高考题：1、 （96 ） we cant get seems bett
