4.不含be動詞變否定句和一般疑問句的用法和例句
1） 若句中有系動詞（be）、助動詞、情態動詞或have （作“有”講）時，將其提到主語前，句末用問號。
例如： He is a first-year student. →Is he a first-year student? I have a pencil-box. →Have you a pencil-box? 2） 如果謂語動詞是行為動詞，則在主語前加Do(Does或Did)，再將動詞還原成原形，在句末加問號。例如： He does morning exercises every day. →Dose he do morning exercises every day? They did some cleaning yesterday. →Did they do some cleaning yesterday？ 特殊疑問句的基本結構是：特殊疑問詞+一般疑問句語序。
但是如果疑問詞在句子中作主語或作主語的定語，就用特殊疑問詞+陳述句語序。常用的疑問詞有：what, who(whom), whose,which,when,where,how,why等，回答時針對問句中的代詞和副詞來回答，不用yes或no來回答。

What were the twins making when their mother came in？ ②Mrs Turner asked her son to [buy some eggs for supper].
