D. 初中英语语法 一般过去式和现在完成时区别练习

1、Both his parents look sad .Maybe they _________what's happened to him .

A. knew B. have known C. must know D.will know
答案 是 B . 因为原句中 Maybe 以表示“推测”, 用完成时表示对现在造成的“影响和结果”。 注意: 不要误选答案 C. 因为,文中并不强调“过去” 的意义。
2、He has _______ been to Shanghai , has he ?

A. already B.never C.ever D. still
选择 B.never 。 因为这是个反义疑问句的结构, 且后边用的是“has he ”, 即肯定疑问式, 根据反义疑问句构成的“前肯后否, 前否后肯”原则, 可知, 前面一定是“否定句”, 只有选项 B never 填入句中,才能构成否定句。 所以, 正确答案是 B.
3、Have you met Mr Li ______?

A. just B. ago C.before D. a moment ago
选择 C.before 这是个现在完成时的结构, 选项 A. just B. ago D. a moment ago 都是一般过去时的时间状语, 所以,都不对。 只有 C before 才能用在现在完成时的句子中。 因此, 正确的答案 是 C 。
4、The famous writer _____ one new book in the past two year
A. is writing B.was writing C.wrote D.has written
正确答案是 D 。
句子意思是:在过去的两年里, 这位著名的作家写了一本新书。
in the past two year 意思是 在过去的两年里, 也包含“现在”, 因此, 属于现在完成时的范畴。 所以, 要选择现在完成时的答案。

5、-Our country ______ a lot so far .

E. 求现在完成时态的语法(初中)

===================
现在完成时的“完成用法”和“未完成用法”

1.现在完成时的"完成用法"

现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束,但该动作对现在产生了影响,与现在情况具有因果关系。

例如:He has turned off the light.他已把灯关了。(动作结束于过去,但说明的是现在的情况--灯现在不亮了。)

现在完成时"完成用法"的特点是动作不延续,因此,该时态只能与表示不定的过去时间状语(如:already,yet,before,recently等)、频度时间状语(如:never,ever,once等)、包括现在时刻在内的时间状语(如:this morning / month /year...,today等)连用。

例如: Have you found your pen yet?你已找到你的钢笔了吗?

2.现在完成时的"未完成用法"

现在完成时的"未完成用法"指的是动作开始于过去某一时刻,一直延续到现在,或可能还要继续下去。

例如:He has lived here since 1978.自从1978年以来,他一直住在这儿。(动作起始于1978年,一直住到现在,可能还要继续住下去。)

I have been in the army for more than 5 years.我在部队已经呆了五年多了。(动作开始于5年前,一直延续至今,有可能还要继续下去。)

此种用法的句中常需一个表示一段时间的状语(由since或for引导),或表示与现在时刻相连的时间状语(如:up to now,so far)等。

例如:I have heard nothing from him up to now.到目前为止我没有他的任何消息。

注意:(1)现在完成时的未完成用法只适用于延续性动词,不可用于终止性动词,即瞬间完成或延续时间很短的动词。如:come,go,arrive,leave,join,become,die等。

(2)现在完成时常见两种句型:

①主语+have / has been+for短语

②It is+一段时间+ since从句

例如:He has been in the League for three years.或It is three years since he joined the League. 他入团已三年了

宾语从句,即:在主句中担当宾语的从句。学习宾语从句要抓住三要素:连接词、语序和时态。

连接词一般都是that(指事务或人),which(指事),who(指人)
1.从句为陈述句,常选择连接词that或将that省略,直接与主句相连。

2.从句为一般疑问句,常选择连接词if或whether。在whether…ornot结构中不能用if替换。

3.从句为特殊疑问句,常选择what,when,where,which,who,how等的疑问代、副词作连接词。

注意:当who为主语时,句式为:who+谓语+其他三:判断时态情况:
1。主句是一般现在时,从句为各种时态情况
2。主句是一般过去时,从句为各种相应过去时态注意:从句描绘客观事实,用一般现在时。
宾语从句与中考试题
学习宾语从句并不难,只要你能过好下面的三道关:
第一关,选好连接词(也有人叫关联词)。
引导宾语从句的连接词,课本上写有三类,但从学习的角度看分为四类更为实用。
1.连词that:只起连接作用,在从句中不作句子成分,也无词汇意义,在口语中或非正式文体中常被省略。例如: 1)He knew(that)he should work hard.
2)I am glad(that)you've passed the exam.
2.连词whether或if:它们起连接作用,在从句中不作句子成分,作“是否”解,口语中多用if。例如: 3)Do you know whether he will ride here at 8 tomorrow morning?
4)Tom didn't know if/whether his grandpa liked the present.
作“是否”解的if和whether在具体用法上差别较大,同学们不易掌握。在宾语从句中用whether没有用if时受到那么多限制。例如:
5)He asked me whether or not I was coming.他问我是否要来。(该句中的whether不能换成if,因为if不能与or连用。)
3.连接代词who,whom ,whose,what, which:它们起连接作用,作句子成分,各有其自己的意义。例如:
6)The teacher asked the new student which class he was in?(武汉市)(which引导宾语从句,在从句中作定语,修饰class,意为“哪个”。)
7)Can you tell me whom he is waiting for?(天津市)
4.连接副词when,where, why,how:起连接作用,分别作时间、地点、原因、方式状语,各有其自己的意义。例如:
8)I wonder where he got so much money.对他从哪里弄到那么多钱我感到疑惑。(where在从句中作地点状语,修饰got,意为“哪里;什么地方”。)
9)He didn't tell me how old his friend was.(四川省)(how引导宾语从句,作程度状语,修饰old,意为“怎样;如何”等意。)
第二关,牢记宾语从句的语序是陈述句语序,即“连接词+主语+谓语+其他”。这里特别强调的是,它的主语和谓语的语序是陈述句的语序,不是疑问句的倒装语序。例如: 10)You must remember what your teacher said.
11)—Dad,do you know when the football game will start?
—In half an hour.(宁波市)
12)汉译英:你能不能告诉我,我们去看望谁?
误:Can you tell me who(m)do we have to see?
正:Can you tell me who(m)we have to see?
错句的错误出在宾语从句中误用了疑问句的结构——主语前加了个助动词do。因为我们已经习惯了特殊疑问句,如W hat time does the plane arrive in Paris?就顺口说出“Do you know what time does the plane arrive in Paris?”这种错误句子来。但是一旦我们注意了,我们不久就习惯于说“Do you know what time the plane arrives in Paris?”了。
第三关,注意时态的呼应。 宾语从句中谓语动词的时态,常常受主句谓语时态的制约,这种现象称为“时态的呼应”。例如:
13)汉译英:我原以为你今天有空的。 误:I thought(that)you are free today.
正:I thought(that)you would be free today.
错句中宾语从句用are很可能是因为有 today,但因为主句谓语是thought,所以从句谓语就该用过去将来时would be了。
这种时态的呼应,如果主句谓语是现在时或将来时,宾语从句的谓语时态不受限制,如上述例句2),3),7),8),10),11),12)。如果主句时态是过去时,宾语从句一般要随着改为相应的过去时(即一般过去时、过去进行时、过去完成时、过去将来时等)。例如: 14)He thought he was working for the people.
15)I heard she had been to the Great W all.
16)John hoped that he would find a job soon.
但宾语从句如果表示定理法则、永恒真理等,则不变化:
17)The teacher told us that the earth moves around the sun.

G. 英语现在完成时语法解答!

时间段 即是一段时间 比如“星期二”,因为星期二是一天,是一个时间段。又比如说“从12点到18点”当然也是时间段了。
时间点 ,即是一个瞬时,很短站的,比如说 12点。这是时间点,就是在钟表指向12点的那一刻。

注意:have been to+a place:表示某人去过某地,现在已经回来了。
如He has been to Shanghai for several times. 意思为他已经去过上海好几次了。
have gone to a place:表示去某地的路上,或者现在还没回来。
如He has gone to Shanghai, so we can't see him now. 他已经去上海了,所以我们现在看不到他了。
