在日常學(xué)習(xí)、工作或生活中，大家總少不了接觸作文或者范文吧，通過文章可以把我們那些零零散散的思想，聚集在一塊,。那么我們該如何寫一篇較為完美的范文呢？下面是小編為大家收集的優(yōu)秀范文,，供大家參考借鑒,，希望可以幫助到有需要的朋友。
sincere的比較級和最高級篇一
英語的應(yīng)用越來越廣泛了,，我們必須好好來學(xué)習(xí)英語知識,。對此小學(xué)頻道編輯為大家整理了小學(xué)六年級英語語法講解：。詳情如下：
i have lived here for more than twenty years.
i have lived here since i was born.
my aunt has worked in aclinic since 1949.
some new oil fields have beeno pened up since1976.
i have known xiaoli since she was a little girl.
my brother has been in the youth league for two years.
ihavenotheardfrommyuncleforalongtime.
注意：并非有for作為時間狀語的句子都用現(xiàn)在完成時,。
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。)
當(dāng)現(xiàn)在完成時+一段時間,，這一結(jié)構(gòu)中,，我們用下面的.公式轉(zhuǎn)化，很容易就能排除非延續(xù)動詞在完成時中的誤使,。
1) (對)tom has studied russian for three years.
=tom began to study russian three years ago, and is still studying it now.
2) (錯)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，它應(yīng)改為harry got married six years ago. 或harry has been married for six years.
希望大家能夠認(rèn)真閱讀這篇小學(xué)六年級英語語法講解：比較since和for,，以便在英語學(xué)習(xí)上取得優(yōu)異的成績,。
