中考网整理了初二英语上册知识点总结现在完成时，供同学们参考。 现在完成时表示在说话时刚刚结束的某一动作或状态，强调对现在的影响，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。 注意have /has been to; have /has/ gone to ;have / has been in 的区别。 I have been toBeijing three times. 我去过北京三次。(曾经去过某地现在已回来) -Where is Linda? I haven’t seen her for two days. -She has gone to London for holiday. She will be back next week. -琳达哪儿去了?我两天没看见她了。 -她到伦敦度假去了。下周回来。(某人到某地去了，现在不在这里) We havebeen inthis 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：一般现在时态形式是am, is, are,过去式是was, were, 现在分词形式是being。 have been in… 在……多长时间了 I have been in the cinema for three hours. 我在电影院里待了3个小时。 三者都是现在完成时态，“have been to+地点”表示去过某处，现在已经回来，不在那里了;而“have gone to+地点”则表示到某处去了，现在还没有回来，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。(现在不在北京) He has gone to Beijing. 他去北京了。(现在在北京或在途中) 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? 注意针对该句型的回答，英汉有别。如果表示“不介意”，常说“No, not at all/please do/go ahead/certainly not”;表示“介意”，则用“I’m sorry, but I do/I’d rather you didn’t/you’d 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 it’s been taken. 对不起，这个位置有人坐。 在3a中小结了几种请求帮助的句子结构，请注意。 肯定结构： Would you mind+doing…? Could you please+do…? Would you please+do? Please+do… 否定结构： Would you mind not doing…? Could you please not do…? Would you please not do…? Please don’t do… (责任编辑：admin) |
