must的反义疑问句must的反义疑问句.ppt

Must 表示猜测的反义疑问句 对现在情况的推测，问句部分用主动词（do,be)一般现在时的适当形式。若是现在进行时，问句部分用现在进行时的适当形式表示。若是there be结构，问句用isn‘t/aren’t there。如： 1)He must be there, isnt he? 2)He must have a big family, doesnt he? 3)He must be waiting outside, isnt he? 4)There must be some students in the room, arent there? 对已发生的过去情况的推测，若陈述句谓语部分有“must have done”，而且有表示过去的时间状语，问句部分用didn‘t；若没有表示过去的时间状语，问句部分用haven’t或hasn‘t。如： 1)They must have gone there last night, didnt they? 2)They must have arrived by now, haven‘t they?（根据by now来判断） 3)They must have been to the Great Wall, havent they? 若是被动，应按被动结构来处理。如： 1)The room must have been cleaned yesterday, wasnt it? 2)The room must have been cleaned, hasnt it? 若句中有表示过去完成时的时间状语，问句部分应用hadnt.如: They must have learnt 5000 English words by the end of last term, hadnt they? (本题中must表推测，如果将它去掉，还原为真实句就是They had learnt 5000 English words by the end of last term.因此，反意问句是hadnt） 第一版 1.people; 目的; because of that In the morning, the students in Class 3 got up early to come to school on time and because of that, they began to be praised by the teacher. 2.让步;even if I will come even if it rains. 3. 原因; who ruled England ; those native 形容词; 本地人, 本国人 is native to India Are you a native base 以….为根据; 名词;基础 The film is based on / upon a true story.
