He didnt tell me _ he went yesterday.4. _ he will go to France has not been decided yet.5. No one knows _ will be the next president.6. _ he will recover soon is till a question.7. He expressed his wish to me _ he could go to Canada to study.总结：选用引导词的技巧：1. 根据句子意思选引导词。2. 分析从句句子成分：缺什么，填什么（1）什么都不缺（不缺成分，不缺意思），填 _ 在_从句中可省略。（2）什么都不缺（不缺成分，但缺“是否”意思），填 _，_只引导宾语从句。（3）缺主，宾， 表, 填连接_（4）缺状语, 填连接_.五、whether 与 if 区别1. I cant decide _to stay.2. I want to know _ its good news or not. 3. His father is worried about _ he can be admitted to a key college.4. _ they can finish the work on time is still a problem. 5. He came to see _ there was wrong with his cat. 总结：表是否1. if 只引导_。2. 在动词不定式之前只能用_。3. 在whether or not 的固定搭配中。4. 在介词后，只能用_。5. 句首用_。总之，凡在从句中表是否，用_就不会错。六、 that, what，which用法区别1. What she wants to know is _ dress she should buy.2. The trouble is _ he has never done the work before.3. _ the earth is round is true. 4._ he wants to tell us is not clear. 5. A modern city has been set up in _ was a wasteland ten years ago.6. Our school is no longer _ it was five years ago.7. He is not _he was a few years ago.8. The color of the flower is different from _ it was in the morning.总结:1._只起连接作用，不作成分，没意义2._ 选择性代词(有范围）3. _有两种含义： （1）什么 （2）的东西/事情 what =the +名词+that七、what与whatever 的区别1. It is very hard for Mary to work there, for_ she does cant satisfy her boss.2. She wouldnt tell me _he said总结：_引导名词性从句时，意为“的事情东西”，暗含具体的事情东西；_相当于anything that，意为“的任何事情东西”，强调各种不同的情况。八、名词性从句中的谓语语气问题。1. She insisted they _ (have) a break. 2. The officer commanded that everyone _ (obey) the rules.3. His pale face suggested he _(be) ill and he suggested that he _ ( send) to the hospital right away . 总结：一个坚持:_v./n. 两个命令: _, _ 三个建议: _v./n., _v./n., _v./n., 四个要求: _, _, _, _ v./n. 等词后面的名词性从句，从句谓语要用_，当从句是被动语态时尤其要注意，此时从句谓语要用_。九、定语从句与同位语从句的区别1. The news _he will come back is true. （ 从句）2. The news _ he told me is true. （ 从句）3. I still remember the day_ I first came to Beijing. （ 从句）4. I have no idea _ she will be back, this week or next week.（ 从句）区分方法：把从句前面的名词名词代入从句中，代得入是_从句，代不入是_从句. 注意：that 在定从中作主，宾，在同位语从句中不作成分。技巧点拨：1. 分析句子结构，确定属于何种从句；2. 分析句子成分，看缺什么成分；3. 根据句子意思确定填什么引导词。练习： 第一部分：基础题1. _ makes his shop different is that it offers more personal services.
