【—since和for語(yǔ)法輔導(dǎo)】對(duì)于英語(yǔ)since和for的知識(shí)講解內(nèi)容,希望同學(xué)們都能很好的看看下面的講解內(nèi)容。
since和for
Since 用來(lái)說(shuō)明動(dòng)作起始時(shí)間,for用來(lái)說(shuō)明動(dòng)作延續(xù)時(shí)間長(zhǎng)度。例如:
I have lived here for more than twenty years.我住在這兒二十多年了。
I have lived here since I was born. 我從出生起就住在這兒了。
注意:并非有for 作為時(shí)間狀語(yǔ)的句子都用現(xiàn)在完成時(shí)。
I worked here for more than twenty years. (我現(xiàn)在已不在這里工作。)
I have worked here for many years.(現(xiàn)在我仍在這里工作。)
注意:用句型轉(zhuǎn)換的方法,很容易排除非延續(xù)動(dòng)詞在有for/since結(jié)構(gòu)的完成時(shí)中的誤用。
1)(對(duì)) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2)(錯(cuò)) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
顯然,第二句不對(duì),它應(yīng)改為 Harry got married six years ago. 或 Harry has been married for six years.
通過(guò)上面對(duì)英語(yǔ)since和for用法知識(shí)的講解學(xué)習(xí),希望同學(xué)們都能從中學(xué)習(xí)的很好,同學(xué)們加油吧。
