Did he go to school yesterday? I will come here tomorrow. I have already finished my homework. 助动词本身没有词义。不能单独做谓语，必须同别的动词连用。 24 助动词do, does, did特点: 1.)无含义; do 实义动词，意为”做”。do homework 助动词,无含义。只用于提问和否定。 e.g. What do you want to do? 助动词 实义动词 25 助动词do, does, did特点: 2.)只在提问和否定时出现; e.g. I don't know his name. 我不知道他的名字。 e.g. Did you go shopping yesterday? 你昨天去购物了吗? 26 助动词do, does, did特点: 3.)句中有实义动词才可能有助动词帮助提问或否定; We are Chinese.

(提问和否定) 2.有无be动词和情态动词? 3. do/does/did? (根据时态和主语选用相应的助动词提问或否定) 4.是否原形? (检验助动词后的实义动词是否为原形) 30 题型1：变句子 He gets up at 7 o'clock every day. (变否定句) He doesn't get up at 7 o'clock every day. 案例分析: ( 1 )原句中没有be动词和情态动词可以帮助否定,应选用助动词; ( 2 )原句不是过去时句子,排除"did" ; ( 3 )原句主语是"He”,是第三人称单数,再排除"do" ; ( 4)选用助动词"does"+ not进行否定; ( 5 )原句动词gets还原成原形get。 31 题型28：翻译句子 你们昨晚看了电视吗? Did you watch TV last night? 案例分析: ( 1 )先判断是否有实义动词,有实义动词才能用助动词提问; ( 2 )判断句子是何时态,过去时直接用did提问; ( 3 )主语填完后注意用动词原形。 32 考点分析 Trees turn green in spring. (改成一般疑问句) _____ trees ______ green in spring? Do turn 解析: 原句没有be动词和情态动词，应用助动词提问;原句是一般现在时的句子，主语trees是复数，应选用助动词do提问,动词仍用原形。答案为Do, turn. 33 精讲精练 单项选择 1. We________go home at 5:30 every day. A. doesn't B. aren't C. don't 2.
