2022 学年牛津上海版英语七年级第二学期语言点及练习 unit3 一、语言点整理 1. (1)She has been a teacher since 1997 自 1997 年以来，她一直是一名教师。 (2)She has been a teacher for quite a few years. 她当教师已经好些年了。  since 是现在完成时的一个标志词  请注意，since 后接“一个时间点”，如：since last Monday/three o’clock 等。Since 还 可以引导时间状语从句，一般来说从句要使用过去时。如 : He has been a teacher since he left the university.  for 后则接“一段时间”，如：for two hours/months 等，又如：Aunt Judy and Uncle Jack have lived in Los Angeles for six years.  现在完成时基本结构： have/ has done(动词的过去分词)。  在现在完成时的句子中如果有 since/for 引导的时间状语，句子中的谓语就表示持续 的动作涵义，必须使用持续性动词，而不可使用短暂性动词。 Eg: 1) I have been in the club for three years. √ 2) I have joined the club for three years. X (join 是短暂性动词) 对 since/for 引导的时间状语提问要使用 How long  She has been a teacher for a quite a few years. 她当老师有好几年了？ How long has she been a teacher? 她当老师多久了？ 2. Aunt Betty works in a company in Beijing, doesn’t she?贝蒂姨妈在北京一家公司工作，对吗？ (1) 反义疑问句结构：陈述句，+助动词/be 动词/情态动词(肯 or 否) +主语的人称代词 (2) 陈述部分为肯定，疑问部分为否定；陈述句部分为否定，那么疑问部分必须为肯定 (3) 在反义疑问句中陈述部分的动词和时态必须与疑问部分的动词和时态相匹配 (4) 疑问部分只能使用人称代词，如 you, he,we, they 等，不能使用名字或名词，如 Tom, her aunt 等都是不行的。 (5) 当陈述部分含有有否定词如 never, no, few, little hardly seldom 等时，陈述部分为否定 句，这时疑问部分必须为肯定 (6) 当陈述部分含有由 un-, im-, in-, dis-等否定意义的前缀构成的词语时，陈述部分还是 肯定句，后面的疑问部分仍然要使用否定形式。Your father is unhappy, isn’t he? (7) 所有的祈使句，包括 Let us…, 疑问部分用 will you? (8) Let’s … 疑问部分用 shall we? (9) 反义疑问句回答：根据实际情况作答；回答方式同一般疑问句； 3.
