现在完成时用来表示之前已发生或完成的动作或状态，其结果的确和现在有联系。动作或状态发生在过去　但它的影响现在还存在；也可表示持续到现在的动作或状态。其构成： have (has) +过去分词
比较过去时与现在完成时
1）过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作； 现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。
I saw this film yesterday. 　　（强调看的动作发生过了。）I have seen this film. 　（强调对现在的影响，电影的内容已经知道了。）　
一般过去时的时间状语: yesterday, last week，…ag, in1980, in Octber, just nw, … 具体的时间状语现在完成时的时间状语fr, since, s far, ever, never, just, yet, till / until, up t nw, in past years, always,… 不确定的时间状语
2）过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。
3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, learn, wrk, study, knw. 过去时常用的非持续性动词有cme, g, leave, start, die, finish, becme, get married等。

Jasper White is ne f thse rare peple wh believe in ancient myths. He has just bught a new huse in the city, but ever since he mved in, he has had truble with cars and their wners.
ne f …… ……其中之一 注意：f后面一定要用可数名词复数或集合名词 ne f the studentsbelieve in 信任; 信仰 Have truble with 与……有摩擦
Jasper White is ne f thse rare peple wh believes in ancient myths.wh 在这是关系词, 起承上启下的作用先行词：ne f the rare peple
如果在定语从句中出现了ne f作为先行词, 它后边的关系代词指代的是后面的复数名词如果在ne f前面还有一修饰词 (the) nly,那么后边的关系代词将指代ne这个词, 才作单数看He is the nly ne f thse rare peple wh believes in ancient myths.
One f 在句中作主语，那么动词选择单数形式例句：其中的一个答案是对的。 One f thse answers is right.
When he returns hme at night, he always finds that smene has parked a car utside his gate. Because f this, he has nt been able t get his wn car int his garage even nce.
Because f +n./prn./ding 由于Because+从句Even nce 甚至一次（否定句中）
Jasper has put up 'N Parking' signs utside his gate, but these have nt had any effect.
Put up 张贴，搭起Have nt had any effect没有效果=have had n effect
Nw he has put an ugly stne head ver the gate. It is ne f the ugliest faces I have ever seen. I asked him what it was and he tld me that it was Medusa, the Grgn.
