这是一份译林版八年级英语下册期中复习讲义 Unit 4 A good read 考点12：疑问词 + 动词不定式含答案，文件包含百校二B道法试卷pdf、百校二B道法答案pdf等2份试卷配套教学资源，其中试卷共10页， 欢迎下载使用。
一、基本结构
疑问词（what, which, wh, whm, whse, when, where, hw）+ 动词不定式（t d）
这种结构可以在句子中作主语、宾语、表语等成分，相当于一个名词短语。
I dn't knw what t d. (我不知道该做什么。)
Can yu tell me hw t get there? (你能告诉我怎么去那里吗？)
The questin is where t g. (问题是要去哪里。)
二、常见疑问词及用法
1. what + t d — 表示“做什么”
I dn't knw what t say. (我不知道该说什么。)
She taught me what t d. (她教我该做什么。)
2. hw + t d — 表示“怎样做”
Please shw me hw t start the cmputer.
D yu knw hw t slve this prblem?
3. where + t d — 表示“在哪里做”
I wnder where t g fr the hliday.
Can yu tell me where t buy the ticket?
4. when + t d — 表示“什么时候做”
Please tell me when t leave.
He can't decide when t start.
5. which + t d — 表示“选择哪一个做”
She can't decide which t chse.
Tell me which t buy.
6. whether + t d — 表示“是否做”（whether相当于if）
I haven't decided whether t g r nt.
She wndered whether t accept the invitatin.
三、常见动词搭配
以下动词后常接“疑问词 + 动词不定式”结构：
• knw — D yu knw hw t use this app?
• tell — Please tell me when t leave.
• shw — Can yu shw me hw t get there?
• teach — She taught me what t d.
• decide — He can't decide where t g.
• ask — He asked me where t put the bx.
• learn — I'm learning hw t ck.
• frget — I frgt what t say.
四、与宾语从句的转换
“疑问词 + 动词不定式”结构通常可以转换为宾语从句，反之亦然。但要注意：当主句主语与从句主语一致时，才能用不定式结构简化。
I dn't knw what I shuld d. → I dn't knw what t d.
Can yu tell me hw I can get there? → Can yu tell me hw t get there?
She hasn't decided where she will g. → She hasn't decided where t g.
注意：如果宾语从句的主语与主句主语不一致，则不能直接转换为不定式结构。
I want t knw where she will g. (不能改为 where t g，因为主语不同)
五、经典例题解析
例1： I dn't knw ______ (what/hw) t d next.
答案：what。解析：what t d表示“做什么”，hw t d后需要加宾语，如hw t d it。
例2： Can yu tell me ______ (where/what) t get t the statin?
答案：hw。解析：问“怎么去车站”，用hw t get there。
例3： Please shw me ______ (hw/when) t start this nline tur.
答案：hw。解析：问“如何开始”，用hw。
例4： She can't decide ______ (which/what) bk t read first.
答案：which。解析：从多个中选择，用which。
例5： I haven't decided ______ (whether/if) t g t the party.
答案：whether。解析：whether t d是固定搭配，if不能用于不定式前。
