大家好，我是小环，我来为大家解答以上问题。划线平板，划线很多人还不知道，现在让我们一起来看看吧！

做“对句子划线部分提问”试题时，一般应该遵循三个步骤：

1. 确定与句子划线部分相应的特殊疑问词，并且特殊疑问词代替相应的划线部分。

2. 把特殊疑问词代替划线部分后的句子变成一般疑问句。

3. 最后再把特殊疑问词提到句首。

以上三个基本步骤可以用三个字来概括，即：定，问，提。例如：

This is a book ?

①This is what. ②Is this what ? ③What is this ?

注意：句①②只是一种变化过程，不必写入试题中。句③才是试题所要求的形式和结果，必须写到试题上。以上三个步骤是对句子划线部分提问最基本的过程。然而对不同句子的不同成份提问时，还要注意以下几点：

1. 如果句子的划线部分是主语，只找出相应的特殊疑问词，用来代替划线部分即可。如：

1)He teaches us English. Who teaches us English？

2)My mother’s clothes are over there. Whose clothes are over there？

2. 如果句子的划线部分是谓语(包括谓语动词)，不论原来的谓语动词是何种形式(时态、语态)，都要将谓语动词变为do的相应的形式：不论原来的谓语动词后面跟的是人、物还是地点，一律用What来代替。如：

1)They are playing football.

①They are doing what. ②Are they doing what？ ③What are they doing？

2)They wolf is going to kill that man.

①They wolf is going to do what. ②Is the wolf going to do what？

③What is the wolf going to do？

3. 如果句子的划线部分是定语，并且在谓语部分，这时，需将特殊疑问词和紧跟其后的名词一起提到句首。如：

1)That is his pen.

①That is whose pen. ②Is that whose pen？ ③Whose pen is that？

对定语划线部分提问题，如果划线部分是所属关系，特殊疑问词用whose；如果划线部分指具体的“某一个”时特殊疑问词用which；如果划线部分指内容或职业时，特殊疑问词用what；如果划线部分指数量时，特殊疑问词用how many(可数)或how much(不可数)。如：

1) They are the legs of the desk.

①They are whose legs. ②Are they whose legs？ ③Whose legs are they？

2)I like red one.

①You like which one. ②Do you like which one？ ③Which one do you like？

3)They have five English books.

①They have how many English books. ②Do they have how many English books？

⑤How many English books do they have？

【经典范例引路】

例1 We go to the school library twice a month. (对划线部分提问)

do you go to the school library？

(2001年四川省中考题)

简析：句子的划线部分为twice a month，表示频率，对表示频率的时间状语提问要用how often。故答案为 How often。

例2They needed to climb up the tree with ladders. (对划线部分提问)

they to climb up the tree with？

(2001年济南市中考题)

简析：①根据句子的划线部分ladders表示物，应用疑问代词what来代替划线部分。②把what代替划线部分ladders的句子变成一般疑问句为：Did they need to climb up the tree with what？③把特殊疑问词 what提到句首为：What did they need to climb up the tree with？故答案为：What did，need。
