现在完成时 (Present Perfect)
现在完成时表示过去发生的某一动作对现在造成的影响或产生的结果；或这一动作开始于过去，持续到现在，并将继续下去。
构成：1. 肯定句
现在完成时的肯定句式是
“have (has)＋过去分词”。
注意：该句式中的have或has是助动词，has用于第三人称单数，其它人称一律用have。
2. 否定句：现在完成时的否定句式是
“haven’t（hasn’t）＋过去分词”。
3. 疑问句：现在完成时的一般疑问句式
是把助动词have或has提到主语之前。
回答用Yes, …have (has). /No, …haven’t (hasn’t).
连用时间状语：already, yet, ever, never, just, before, several times 等。
注意：当have被用在现在完成时态中时，它可以和前面的代名词一起组成缩写形式。
我曾经到过纽约。
I’ve been to New York once before.
我刚丢了我的铅笔盒。
I’ve just lost my pencil-box.
注意：never, ever一般置于助动词have/has之后，过去分词之前。
1. never 从来没有，从不，表示否定
He has never seen such a tall building.
他从未见过这么高的楼。
2. ever 曾经，主要用于疑问句
Have you ever wanted to travel around the world
你曾经想要周游世界吗？
have been to与have gone to 的区别
1. have (has) been to意为“曾经去过某地”，表示现在已经不在那里了。可与just, ever, never等连用。如：
I’ve just been to the post office.
我刚才去邮局了。
Have you ever been to Hangzhou
你曾经去过杭州吗？
Mary has never been to the Great Wall.
玛丽从未去过长城。
have (has) been to 后面可接次数，表示去过某地几次。
I’ve been to Beijing three times.
我去过北京三次。
They have been to that village several times.
他们去过那个村庄好几次了。
2. have (has) gone to 意为“到某地去了”，表示到了某地或正在去某地的途中。总之，说话时该人不在现场，一般不用第一、第二人称代词作句子的主语。如：
Where is Tom 汤姆在哪里？
- He has gone to the bookshop.他到书店去。
同学们要注意现在完成时与一般过去时的区别。虽然这两个时态都和过去发生的事情有关，但是现在完成时强调这一动作与现在的关系，如对现在产生的结果、影响等，而一般过去时只表示过去的事实，不表示和现在的关系。如：
I have just been to London. I went there last month.
我刚去过伦敦，是上个月去的。
I have been to the science museum many times. I went there on our last summer vocation.
我已经去了科学博物馆很多次。 上个暑假我还去了呢。

B: No, I’ve already _____ (be) there three times.
2. A: Have you ____ (see) the robots at the science museum
B: Yes, I _____ (go) there last weekend.

Mr. White came to our school in 2008, and since then he ________ us English.
A. teaches B. taught
C. has taught D. will teach
答案：C
【解析】考查动词时态。从since then知应该用现在完成时态。
Do you know ________ she went to the movie last night
— On foot.
A. when B. why C. how
答案：C
【解析】疑问副词的用法。从答句On foot可以看出问句是有关交通方式的，when表示“什么时间”；why表示“为什么”，how表示“怎么”，对交通方式提问一般用how，因此本题选C。
– How do you study for a test
-- _____ working with friends.
A. By B. With C. On
答案： A
【解析】本题考查介词by的用法。by意为“通过……方式”；with意为“和……在一起”；on意为“朝,向”.句意“你是怎么为考试作准备吗？”“通过和朋友一起学习。”只有by具有“通过……方式”的意思，故选A。
