就划线部分提问，是用一个合适的疑问词去替代句中的某一成分，使之成为一个特殊问句。其方法主要是：先依据语意选择相应的疑问词和疑问句语序，句末改用问号。这时我们要注意以下几点：
(1)选择恰当的疑问词。
(2)对主语或主语的定语提问时，用陈述句语序。对定语提问时，所修饰的名词应放在疑问词后。
(3)对其它成分提问，用“疑问词+一般疑问句”语序。如：
My
grandpa has been in Shanxi
for ten years.
→Who has been in Shanxi for ten
years?
Lily’s dog has lost.
→Whose dog has lost?
Emma
bought one dictionary yesterday.
→How many dictionaries did Emma buy
yesterday?
句型转换设题广，部分试题难度较大，这就要求同学们有扎实的语言基本功和熟练的解题技巧。
对于按要求改写句子的试题：首先应注意“要求”的内容；二是要注意选词的准确；三是要注意各种句型的特殊点；四是要注意大小写和拼写的正确。如：
1. The
maths problem is too difficult for him to work out. (改为复合句)
The maths
problem is ______ difficult _____ he can’t
work it out.
2. The
surfers both won first prize in the city surfing competition. (改为否定句)
_____
______ the surfers won first prize in the city surfing competition.
3. I
think the fastest way to travel is by plane. (改为特殊疑问句)
____ do
you think the fastest way to travel ______?
4. Miss
Li showed us a picture of the feathered dinosaur. (改为被动语态)
We _____
______ a picture of the feathered dinosaur by Miss Li.
答案与简析：
1. too…to…(太……而不能……)＝so …that …not (如此……以致……不……)，所以，应该填so, that。
2. 从转换后的句式中没有明确的否定词not可知不能用助动词加not的形式来完成。再根据both的反义词是neither，主语又是the surfers，因此应填Neither
of。
3. 本题实际上是对“by plane”提问，改换后的句子只是缺少了“is by plane”，因此，该将“by plane”改为“what”，后一个空用“is”。
4. 由showed确定要用一般过去时的被动语态，故填were shown / showed。
