65. by chance(=accidentally, by accident)偶然追问对于现在完成时态 你了解吗？？？？
能教教我吗？？？？？？？？？？？？？？回答直接在百度里搜现在完成时，里面有很详细的讲解
句型：基本结构：主语+have/has+动词的过去分词
用法（1）现在完成时用来表示现在之前已发生过或完成的动作或状态,但其结果却和现在有联系,也就是说,动作或状态发生在过去但它的影响现在还存在，也就是说，动作发生在过去，而对现在造成的影响和结果. I have spent all of my money.(现在我没有钱花了.) Jane has laid the table.(Jane现在桌子已经摆好了.) Michael has been ill.(现在仍然很虚弱) He has returned from abroad. (现在已在此地)
（2）现在完成时可以用来表示发生在过去某一时刻的,持续到现在的动作（用行为动词表示）或状态（be动词表示）常与for（+时间段）,since（+时间点或过去时的句子）连用. ①for+时段 为…时间 ②since+过去一个时间点（译为：自从……以来） ③since+时段+ago ④since+从句（过去时） ●⑤It is+时段+since+从句（过去时） Mary has been ill for three days. I have lived here since 1998.
1.现在完成时不能单独与准确时间连用，(如表示过去的时间状语） 如yesterday(morning、afternoon),last(morning、afternoon)等，除非与for,since连用.
2.现在完成时往往同表示不确定的过去时间状语连用 ,如already（肯定）, yet（否定，疑问）, just, before, recently,still, lately,never等: He has already obtained a scholarship. I haven't seen much of him recently (lately).
3. 现在完成时常常与表示频度的时间状语连用, 如often, sometimes, ever, never, twice, on several occasion等: Have you ever been to Beijing I have never heard Bunny say anything against her. I have used this pen only three times. It is still good.
4. 现在完成时还往往可以同包括现在时间在内的时间状语连用, 如now, up to these few days/weeks/months/years, this morning/week/month/year, just, today, up to present, so far等: Man has now learned to release energy from the nucleus of the atom. There has been too much rain in San Francisco this year. 5. 现在完成时还可以用来表示过去的一个时间到现在这段时间内重复发生的动作.
