A. that  B. what  C. if  D. why 【答案】C 【详解】句意：她想知道这是否正常。此处用if引导宾语从句，表示"是否"。故选C。 【练习2】I'm not sure ______ talking about it will help. A. that  B. if  C. what  D. why 【答案】B 【详解】句意：我不确定谈论这件事是否有帮助。此处用if引导宾语从句，表示"是否"。故选B。 考点2：疑问词引导的宾语从句 【定义】疑问词（what, why, how, where, who, when, whose, which等）引导的宾语从句用于表达一个特殊疑问句的含义。 【结构公式】主句 + 疑问词 + 陈述句语序（主语 + 谓语 + 其他）. 【用法分类】 用法一：疑问代词引导 常见的疑问代词有：what, who, whom, whose, which（在从句中充当主语、宾语或定语）。 例句：Many teenagers do not know what they should do about it.（what作do的宾语） 例句：They do not know who they can ask for advice.（who作ask的宾语） 用法二：疑问副词引导 常见的疑问副词有：when, where, how, why（在从句中充当状语）。 例句：They are not sure how they can have an honest dialogue with their parents.（how作方式状语） 例句：I don't know where I can find useful articles.（where作地点状语） 【要点详解】 宾语从句必须用陈述句语序：疑问词 + 主语 + 谓语 + 其他。 疑问词在从句中充当一定的句子成分（主语、宾语、定语、状语等）。 疑问词引导的宾语从句中，疑问词不可以省略。 【练习1】I don't know ______ I should do about it. A. that  B. if  C. what  D. whether 【答案】C 【详解】句意：我不知道我应该对此做什么。what在从句中作do的宾语。故选C。 【练习2】They are not sure ______ they can have an honest dialogue with their parents. A. what  B. how  C. that  D. if 【答案】B 【详解】句意：他们不确定如何才能与父母进行诚实的对话。how在从句中作方式状语。故选B。 考点3：if/whether引导的宾语从句 vs 疑问词引导的宾语从句 【定义】if/whether引导的宾语从句对应一般疑问句；疑问词引导的宾语从句对应特殊疑问句。 【用法对比】 if/whether引导：从句是一般疑问句含义，用if/whether连接，语序为陈述句语序。 例：She wonders, "Is this normal？" → She wonders if this is normal. 例：He asks, "Does she have any advice？" → He asks whether she has any advice. 疑问词引导：从句是特殊疑问句含义，用疑问词连接，语序为陈述句语序。 例：I ask, "What should I do？" → I ask what I should do. 例：She wonders, "How can I control myself？" → She wonders how she can control herself. 考点4：提建议的句型 【定义】针对他人遇到的问题，使用特定的句型给出建议和帮助。 【常用句型】 （1）You should (not) do sth. 你（不）应该做某事。 例：You should start going to bed earlier. （2）You should try to do sth. 你应该设法做某事。 例：You should try to manage your time better. （3）Why not do sth？ 为什么不做某事呢？ 例：Why not try some breathing exercises？ （4）Maybe you could do sth. 也许你可以做某事。 例：Maybe you could spend more time with friends. （5）It is important to do sth. 做某事很重要。 例：It is important to communicate well with our parents. （6）My advice is to do sth. 我的建议是做某事。 例：My advice is to talk to someone you trust. （7）Have you tried doing sth？ 你试过做某事吗？ 例：Have you tried talking to your friends？ （8）Do remember that... 务必记住…… 例：Do remember that you are not alone. 【练习1】针对以下问题给出建议。 （1）I feel tired because I stay up late. （2）I often waste time on my mobile phone. （3）I'm under a lot of stress at school. （4）I don't get along well with my parents. 【答案】 (1) I feel tired because I stay up late.

You can also talk with your teachers. (4) I don't get along well with my parents. You should communicate with them patiently and share your feelings more often. Try to understand each other. 考点5：短暂性动词与延续性动词在现在完成时中的转换 【定义】在现在完成时中，若要与for + 时间段或since + 时间点连用，短暂性动词（瞬间动词）需要转换为相应的延续性动词（状态动词）。 【用法对比】 短暂性动词 → 延续性动词 （1）borrow → keep （2）buy → have （3）arrive → be in / be at （4）leave → be away (from) （5）die → be dead （6）join → be in / be a member of （7）begin / start → be on （8）finish → be over （9）open → be open （10）close → be closed 【要点详解】 短暂性动词不能与表示一段时间的状语（for + 时间段，since + 时间点）连用。 必须将短暂性动词转换为相应的延续性动词才能与时间段连用。 例：I have bought this book for two years.（×） I have had this book for two years.（√） 【练习1】I ______ this book for two years. A. have bought  B. bought  C. have had  D. had 【答案】C 【详解】句意：我买这本书两年了。for two years表示一段时间，buy是短暂性动词，需转换为have。故选C。 06 重点归纳 一、if/whether引导的宾语从句 （1）结构：主句 + if/whether + 陈述句语序。 （2）if和whether都表示"是否"。 （3）whether更正式，常用于书面语。 （4）从句中有or not时常用whether。 二、疑问词引导的宾语从句 （1）结构：主句 + 疑问词 + 陈述句语序。 （2）疑问词在从句中充当句子成分。 （3）常见的疑问词：what, who, whom, whose, which, when, where, how, why。 三、提建议常用句型 （1）You should (not) do... （2）You should try to do... （3）Why not do...？ （4）Maybe you could do... （5）It is important to do... （6）My advice is to do... （7）Have you tried doing...？ 四、短暂性动词与延续性动词的转换 borrow → keep buy → have arrive → be in / be at leave → be away (from) die → be dead join → be in / be a member of begin / start → be on 07 过关检测 一、单项选择（共10题） 1.
