What is that?
划线提问用“替换法”.
第一步,用what替换掉a car.句子变成That is what.
第二步,将what这个特殊疑问词移到句首.句子变成What that is.
第三步,将谓语动词is提到主语that的前面.句子变成What is that.
其他注意点：
（一）如果划线部分是人,则用who替换它；如果划线部分是物,则用what替换它；如果划线部分是时间,用when替换它；如果划线部分是地点,用where替换它；如果划线部分是原因,用why替换它；如果划线部分是方式,用how替换它；如果划线部分是价钱,用how much替换它；如果划线部分是数量的多少,用how many/much替换它；如果划线部分是长度,用how long替换它；如果划线部分是宽度,用how wide替换它……
（二）如果谓语动词是系动词,或是情态动词（如can,may,must,need等）,或是助动词(如will,shall,have等）,则直接将系动词、情态动词或助动词提到主语的前面.
（三）如果谓语动词是实义动词,则借用一个助动词do（一般现在时的第三人称单数形式是does,过去式是did）,然后将助动词do提到主语的前面.借用了do之后,后面的谓语动词用原形.如：
She goes to school by bike.（划线部分是by bike）
----How does she go to school?
