2023年初中英语现在完成时语法归纳总结及练习

现在完成时语法归纳总结及练习(含答案)

现在完成时表示发生在过去持续到现在完成或未完成的事情，对现在造成了某种影响或产生了某种结果。也表示到现在为止从未做过的事情。

现在完成时的谓语动词构成是：have/has+动词的过去分词(过去分词用P.P.表示)，have/has叫助动词，变成否定形式是：haven’t /hasn’t +过去分词，变一般疑问句就是把have、has提到主语前面，标点用问号,用yes、no回答。例如：I have ever seenthe film before. I haven't seen the film. Have you seen the film before?Yes，I have. No, Ihaven't.

动词的过去分词的变化规则和过去式的规则是一样的。分为规则变化和不规则变化。规则变化和动词变过去式的方法一样。不规则变化没有一定的规律性，得需要背诵。

一：把下列动词变成过去分词：

1.enter _____ 2. afford _______ 3. invite______ 4. try ______

5. stop______ 6. smell _______ 7. send _____ 8. dream _____

9. do______ 10. get ______ 11.feel ______ 12. make _____

在学习现在完成时态时，我们有时用一些词加以强调或说明。如：just(刚刚，刚才)，already(已经), ever(曾经), never(从不), yet(还未). just一般用在肯定句中，放在have/has和过去分词之间;already用于肯定句，放在have/has和过去分词之间或句尾。ever一般没有句式限制，放在have/has和过去分词之间;never表示否定意义，放在have/has和过去分词之间;yet用于否定句或疑问句句尾，在否定句中一般翻译为：“已经”，在疑问句中一般翻译为：“尚，还未”。另外还有一些词也可用于现在完成时，如：before(以前)，一般放在句尾。so far(到目前为止)，可放句首也可放句尾。recently(最近)一般放句首。以上这些词是现在完成时的标志词，见到这些词可用现在完成时。

二：把下列句子变成否定句和一般疑问句。

1.I have done some pizza.

I ______ _______ any pizza.

_____ you _____ any pizza?

2.David has ever seen the film before.

David _____ ever ______ the film before.

_____David ever _____ the film before?

3.The spaceship has already arrived Mars.

The spaceship _____ _____ Mars _____.

_____the spaceship _____ Mars _____?

二:用just，before，so far，never，already, yet填空

1._____ he hasn't finished reading the book about space.

2.They have ____ watched a wonderful football match.

3.--Have you finished your homework _____?

-- Not ____. I need another hour.

4.Gina has ____seen the film twice.

5.My grandmother has ____ been to the Great Wall.

6.Linda has ever travelled around Europe _____.

要表达某一行为或状态从过去某一时间一直持续到现在，我们也可借助现在完成时，通常要与表示一段时间的时间状语连用，这类状语通常由for或since(自从)引导。for后接一段时间，如：for a long time,for five years等;since后接表示过去的时间点，如：since 2003, sincetwo years ago, since last Friday等。另外since也可引导一个时间状语从句，这个从句要用一般过去时，它前面的主句用现在完成时。

三：用for或since填空

1.Mrs. Smith has been in Beijing ____ a long time.

2.They've been good friends ____ they were little kids.

3.Kate has been a member of the dancing club ____ two years ago.

4.He has studied at No. 1 Middle School ____ three years.

5.The boy has been ill ____ last Friday.

上文提到的“for和since+时间点或从句”都表示段时间，此时句子的谓语动词需要用延续性动词(即动词所表示的动作可以持续一段时间)，常见的延续性动词有：learn(学习); work(工作); live(居住); know(知道); walk(散步); watch(观看); sleep(睡觉); stay(呆，逗留); wait(等候，等待); keep(保持); last(持续)等等。

常见的非延续性动词有：open(打开);close(关闭); die(死，去世); leave(离开); begin(开始); come(来); go(去); borrow(借入); lend(借出，借给); buy(买); move(移动); join(加入)等等。非延续性动词可以用现在完成时，说明某个动作的结果还存在，但不能和段时间连用。在否定句中非延续性动词可以和表示一段时间的状语连用。

非延续性动词可以和延续性动词转换：

(1)转换成与其意思相对应的延续性动词

buy-- have; borrow--- keep; put on--- wear;

catch a cold--- have a cold have got--- have

(2)转换成“be+形容词、副词、介词、名词”的形式。

come/go/arrive--- be in/at +地点

begin/start--- be on finish/end/stop--- be over

open--- be open close--- be closed

die--- be dead leave--- be away

fall asleep--- be asleep join --- be a member of/ be in

come back--- be back become--- be

wake up --- be awake
