            • 現(xiàn)在完成時(shí)

              強(qiáng)調(diào)“哥已經(jīng)過了哈哈哈”,可以在have/has后加上already。例如: I have already passed CET 4. 對于那些考試沒過,或是不知道過沒過的同學(xué)來說,不好意思,already這個(gè)詞就不適合大家了,咱們還是老老實(shí)實(shí)的在句尾用yet吧,意思是“還沒有”: I have not passed CET 4 yet. (我還沒有通過四級考試。) Have you passed CET 4 yet?(你通過四級考試了嗎?) 值得注意的是,英美兩國人民對already和yet的用法有不同意見:嚴(yán)謹(jǐn)古板的腐國人民認(rèn)為,already和yet只能用于現(xiàn)在完成時(shí);但活潑奔放美國人覺得,和一般過去時(shí)連用也不是不可以哦。 上現(xiàn)在是CC貓冷笑話時(shí)間: 問:最美的英語時(shí)態(tài)是什么? 答:當(dāng)然是禮物般完美的現(xiàn)在完成時(shí)面的現(xiàn)在完成時(shí)例句中,并沒有提及具體時(shí)間。如果要涉及具體時(shí)間,就要用到since或for這兩個(gè)介詞了。 Beijing has been the capital of the People's Republic of China since 1949. (從1949年起,北京就是中國的首都。) Beijing has been the capital of the People's Republic of China for almost 70 years. (北京成為中國的首都已經(jīng)差不多70年了。) 從上面的例句我們可以看出,since后面加時(shí)間點(diǎn)(1949年),而for后面加時(shí)間長度(70年)。切記切記,現(xiàn)在完成時(shí)后面不能直接加時(shí)間點(diǎn),千萬不要漏掉since啊。 CC Cat has taught me English last year. 摔!since呢? CC Cat has taught me English since last year. 乖!這才是本喵的好學(xué)生。 其實(shí),現(xiàn)在完成時(shí)和一般過去時(shí)最容易混淆,本喵專門為臉盲的同學(xué)準(zhǔn)備了《時(shí)態(tài)比較:現(xiàn)在完成時(shí)與一般過去時(shí)》,約不?

              上了) I have already cleaned the room. 我剛剛已經(jīng)打掃了房間。(說明現(xiàn)在房間已經(jīng)干凈了) 這兩個(gè)例子說的就是“過去發(fā)生的動(dòng)作對現(xiàn)在產(chǎn)生的結(jié)果或影響。” 下面大家來翻譯這個(gè)句子:我的爸爸在這家工廠工現(xiàn)在完成時(shí)作了很多年了。 答案揭曉:My father has worked in this factory for many years. 這個(gè)例子說的是“過去發(fā)生的動(dòng)作延續(xù)到現(xiàn)在,而且還將繼續(xù)下去,往往與表示一段時(shí)間的狀語連用?!?再來翻譯一個(gè)句子:我去過長城很多次了。 答案揭曉:I’ve been to the Great Wall many times. 這個(gè)例子表達(dá)的是“從過去到現(xiàn)在所經(jīng)歷的事情?!?當(dāng)然了,大家在完成現(xiàn)在完成時(shí)的習(xí)題時(shí)也會(huì)有迷惑選項(xiàng)哦,比如一般過去時(shí)。雖然兩者都表示過去的動(dòng)作,但現(xiàn)在完成時(shí)強(qiáng)調(diào)這一動(dòng)作與現(xiàn)在的關(guān)系,對現(xiàn)在產(chǎn)生的影響或結(jié)果,而一般過去時(shí)則只表示過去的事實(shí),不表示與現(xiàn)在的關(guān)系。 最值得提醒大家的是這一點(diǎn):現(xiàn)在完成時(shí)不能和具體時(shí)間點(diǎn)連用,而一般過去時(shí)要與具體的時(shí)間點(diǎn)連用。 我們試著來翻譯這兩句話: 1、我這些天沒有看見她。 答案揭曉:I haven’t seen her these days. 2、我今天早上看見她了。 答案揭曉:I saw her this morning. 今天的學(xué)習(xí)內(nèi)容就是這些,大家可以時(shí)常翻閱,溫故知新哦!總之,要想熟練準(zhǔn)確掌握這個(gè)知識點(diǎn),同學(xué)們還需要做有針對性的鞏固練習(xí),記住熟能生巧。學(xué)習(xí)其他的英語語法知識,也可以來關(guān)注我們。我們將為大家呈現(xiàn)更多有用的知識點(diǎn)。

(the activity and its consequences: this is what he’s been doing for the last hour and why he is exhausted now.) 3、現(xiàn)在完成進(jìn)行時(shí)表示重復(fù)的動(dòng)作時(shí),不能同表示具體數(shù)字的詞并用。 I’ve posted a dozen postcards, but received none. I’ve read this book several times. I’ve been posting postcards since early December. 4、現(xiàn)在完成進(jìn)行時(shí)帶有較為強(qiáng)烈的感情色彩。 You have been disturbing me. 5、許多狀態(tài)動(dòng)詞不能用完成進(jìn)現(xiàn)在完成時(shí) 1、表示過去開始并持續(xù)到現(xiàn)在的動(dòng)作。(動(dòng)詞必須是持續(xù)動(dòng)詞) China?has changed a great deal in the past 20 years.? 2、強(qiáng)調(diào)過去動(dòng)作對現(xiàn)在行時(shí)。 I’ve known that for a long time.? The strike has lasted six months. 6、有少數(shù)動(dòng)詞用兩種時(shí)態(tài)都可以,但若強(qiáng)調(diào)時(shí)間長度時(shí)用完成進(jìn)行時(shí)較好。 They have been working this term. They?have worked very well this term.
