Grammar
现在完成时
1.现在完成时含义：
（1）表示过去发生或已经完成的某一动作对现在造成的影响或结果；
（2）表示从过去开始一直延续到现在的动作或保存的状态。
2.现在完成时的结构：主语+ have / has +动词的过去分词
3.现在完成时的句式：
肯定句：主语+ have / has +动词的过去分词(+其他).
否定句：主语+ have / has + not +动词的过去分词(+其他).
一般疑问句：Have/ Has +主语+动词的过去分词(+其他)
答语：Yes, 主语+have / has.
或No, 主语+ haven’t / hasn’t.
4. have been to与have gone to的区别
比较：
He has been to Beijing. 他曾去过北京。（人已回来）
He has gone to Beijing. 他已经去北京了。（人已在北京或是在去北京的路上，不在说话处）
区别：
have / has been (to) 表示“曾经到过某地”，说话时此人不在那里，已经回来。侧重指经历。
have / has gone (to) 表示某人“已经去某地了”，说话时此人可能在路上或已到那里，反正不在说话处。
5.一般过去时与现在完成时的区别
比较：
I have seen the film. 我看过这部电影。 (我了解这部电影的内容)
I saw the film last month. 我上个月看了这部电影。(只说明上个月看了这部电影，不涉及现在的情况)
区别：
①一般过去时只强调过去的动作；现在完成时强调过去的事情对现在的影响。
②一般过去时通常与表示过去的时间状语连用；现在完成时则不能与表示过去的时间状语连用。
③一般过去时单纯表示过去的经历；现在完成时表示过去的动作或状态延续到现在并可能持续下去。
被动语态
语态：表示主语和谓语动词之间的关系。英语有两种语态，即主动语态和被动语态。
主动语态：表示主语是动作的执行者。
被动语态：表示主语是动作的承受者。
1.被动语态的用法
（1）用于不知道或没有必要说明动作的执行者时。例如：
※ My bike was stolen．
我的自行车被盗了。
（2）用于汉语中含有“被”“由”等意的句子时。例如：
※ Tina is asked to come by Paul.
Tina是被Paul叫来的。
2.被动语态的基本构成:
be + done + (by +动作的执行者）
3.不同时态被动语态的基本结构
一般现在时：am / is / are + done + by sb.
一般过去时：was / were + done + by sb.
现在进行时：am / is / are being + done + by sb.
过去进行时：was / were being + done + by sb.
一般将来时：will be / is going to be + done + by sb.
现在完成时：have / has been + done + by sb.
Example:
※ That computer is used by us everyday.
※ That computer was used by us yesterday.
※ That computer is being used by us now.
※ That computer was being used by us at this time of yesterday.
※ That computer will be / is going to be used by us in the future.
※ That computer has been used by us for three days.
