He is our new teacher. →Is he your new teacher? 　　②对一般疑问句的回答要简洁，在yes，no之后，要用人称代词来代替问句中的主语。 　　如：—Were Mike and John sick last week? —Yes, they were. (2) 当谓语动词是行为动词时，必须在句首加上相应的助动词do，does或did，加上这些助动词后，句子中的谓语动词必须用原形。 如：I go to school by subway. →Do you go to school by subway? Mike likes swimming. →Does Mike like swimming? My mother read a magazine yesterday afternoon. →Did your mother read a magazine yesterday afternoon? （3）在把陈述句变成一般疑问句的时候，若句中有some，something，somebody等词，要将之变成any，anything，anybody等。 如：There is some water in the glass.→Is there any water in the glass? Somebody is waiting for you near the gate. →Is anybody waiting for me near the gate? 　　【注】当some 是某些固定搭配词组的组成部分时，则无须变化。这样的词组包括do some shopping,do some cleaning, do some washing, do some reading等。 　　如：I do some shopping with my aunt on Saturday. →Do you do some shopping with your aunt on Saturday?三、特殊疑问句 　　1. 特殊疑问句的概念 　　以特殊疑问词开头的疑问句，叫作特殊疑问句。常见的特殊疑问词包括：what(什么)，when(什么时候)，where(哪里)，why(为什么)，how(怎么样)，which(哪一个)，who(谁)，whose(谁的), 另外还有一些特殊疑问词组，如：what time(什么时间)，what colour(什么颜色)，what size(什么尺码)，how many/much(多少)，how long (多长)，how often(多久)等。　　2. 常见的疑问词（组）及其用法 　　(1)what：用于对指物的名词或动词短语提问。 　　如：This is an orange. →What is this? 　　I am going to play the guitar. →What are you going to do? 　　(2) when：用于对时间提问。 　　如：I read English early in the morning. →When do you read English? 　　John went to the cinema at 8:00 last night.→When did John go to the cinema last night? 　　(3) where：用于对地点提问。 　　如：I study in Chaoyang Primary School. →Where do you study?　　(4)why：用于对事情的原因提问。 　　如：I go to work by subway because it is fast. →Why do you go to work by subway? 　　(5)how：用于对方式或程度等提问。 ... ...
