初二英语上册知识点总结：现在完成时 如今完成时表示在说话时刚刚结束的某一动作或状态，强调对如今的影响，由"助动词have/has +动词的过去分词'构成。翻译成汉语时通常会用到"已经'等字样。 We have learned five English songs this term. 这学期我们已经学了五首英文歌曲。 I have seen this movie. 我已经看过这部电影。 留意have /has been to; have /has/ gone to ;have / has been in 的区分。 I have 〔been to〕Beijing three times. 我去过北京三次。〔曾经去过某地如今已回来〕 －Where is Linda? I havent seen her for two days. －She has 〔gone to 〕London for holiday. She will be back next week. －琳达哪儿去了？我两天没观察她了。 －她到伦敦度假去了。下周回来。〔某人到某地去了，如今不在这里〕 We have〔been in〕this city for 10 years. 我们在这个城市里生活了10年了。〔表示状态〕 辨析：have been in, have gone to 与have been to been是系动词be的过去分词形式。be有多种形式：一般如今时态形式是am, is, are,过去式是was, were, 如今分词形式是being。 have been in 在多长时间了 第 5 页 I have been in the cinema for three hours. 我在电影院里待了3个小时。 三者都是如今完成时态，"have been to＋地点'表示去过某处，如今已经回来，不在那里了；而"have gone to＋地点'则表示到某处去了，如今还没有回来，可能在去的途中，也可能在那里或返回的途中；"have been in＋地点'表示某人在某处待了多长时间。试比较： He has been to Beijing. 他去过北京。〔如今不在北京〕 He has gone to Beijing. 他去北京了。〔如今在北京或在途中〕 He has been in Beijing for two years. 他在北京两年了。 八、Would you mind? 你介意做吗? 这是英语中委婉请求的表达方式，语气委婉、客气、礼貌，易于对方接受。 其结构是would you mind＋动名词＋其他? 留意针对该句型的回答，英汉有别。假如表示"不介意'，常说"No, not at all／please do／go ahead／certainly not'；表示"介意'，则用"Im sorry, but I do／Id rather you didnt／youd better not'等。如： Would you mind my asking you a few questions? 请教您几个问题好吗？ No, please do. 不介意，请讲。 又如： Would you mind if I took this seat? 我可以坐这个座位吗？ Sorry, but its been taken. 对不起，这个位置有人坐。 在3a中小结了几种请求关心的句子结构，请留意。 确定结构： Would you mind＋doing? Could you please＋do? Would you please＋do? Please＋do 否认结构： Would you mind not doing? Could you please not do? Would you please not do? Please dont do 第 6 页 本文来源：https://www.wddqw.com/doc/651be2cdc2c708a1284ac850ad02de80d4d806c9.html
