知识要点二：语法
)
构成
现在完成时是由“助动词have(has）+动词的过去分词”构成
用法
（1）表示动作发生在过去某个不确定的时间，但对现在产生了某种影响或造成了某种结果。句中常有just, already, yet等副词修饰。(注意与一般过去时的区别)
Have you had lunch yet
你已经吃过午饭了吗？
Yes, I have. I’ve just had it.
是的，我刚刚吃过。
（2）表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止，也可能仍然在进行。句中常有for（+时间段）或since（+时间点）引导的表示时间的状语。（注意与现在进行时态和过去进行时态的区别）
He has taught here since 1981.
表示说话前发生过一次或多次的动作，现在成为一种经历，一般意为汉语“.......过”，常带有twice, ever, never，three times等时间状语。
I have been to Beijing twice.我去过北京两次。
just 刚刚 肯定句，have/has 后
never 从来没有 否定句，have/has 后
ever 曾经 疑问句，have/has +主语+ever+过去分词
before 用于句末
yet 仍然 用于疑问句，否定句句末，或not之后
already 已经 肯定句，have/has 后或句末
so far 到目前为止 句首或句末
【语法练习】
用just, already, yet, ever填空。
Have you been to Japan
I have finished my homework.
I have finished my homework .
I haven’t finished my homework .
【答案】1.ever 2.already /just 3.already 4.yet
二、选择题
1.—Mum, I want to watch the news about our school. Change the channel, please!（2020江苏镇江）
—What a pity! It is eight o'clock now. It___________ for a while.
A. has been over B. was over C. has finished D. finished
【答案】A
【解析】句意：——妈妈，我想看我们学校的新闻。请换频道！——真遗憾！现在是八点钟。它已经结束一段时间了。
考查动词时态。has been over已经结束了，现在完成时；was over结束了，一般过去时；has finished已经结束了，现在完成时；finished结束，一般过去时。根据语境可知，学校新闻已经结束了，这件事对“现在不能观看了”产生了影响，故应为现在完成时，故排除B、D两项。另句中for a while表示一段时间，与现在完成时连用时，应用延续性动词，而动词finish为瞬时性动词，不能在现在完成时中与一段时间连用，故排除C项。be over表示延续性动作，可在现在完成时中与时间段连用，即has been over。故选A。
2.—It's ten years since we came here（2019，安徽卷）
—How time flies! We ____ in China for so long.
A. work B. worked C. will work D. have worked
【答案】D
【解析】句意：-自从我们来到这里已经有10年了。-时间过得真快啊！我们在中国工作了这么长时间了。work工作，动词原形；worked工作，一般过去时；will work一般将来时；have worked现在完成时。根据对话的情景以及句中的时间状语for so long可知，这里表示从过去一直持续到现在的一个动作，应用现在完成时，故选D。
3 — The room is very clean. Who __________ （2019·西宁中考）
A. cleaned B. have cleaned C. has cleaned D. will clean
【答案】C
【解析】现在完成时的基本用法：表示过去的动作对现在产生的结果或影响。“房间很干净，”这是现在的结果。是由“clean”这个动作产生的。Clean 这个动作是过去发生的，但结果是现在房间是干净的。所以要用现在完成时态。考查现在完成时最基本的定义。Who 做主语，用单数。
4. Have you ever _________to the Great Wall It’s very beautiful.
A. gone B. been C. went D. go
【答案】B
【解析】have been to 去过某地， have gone to 去了某地。（不再说话的地方）故用：have gone to

— 没，他还没买新手机。(yet)
【答案】 Has Jack bought a new mobile phone yet
No. He hasn’t bought a new one yet.
