AD注意點(diǎn)二:非延續(xù)性動(dòng)詞與現(xiàn)在完成時(shí)短暫性動(dòng)詞在肯定句、疑問句中不能與時(shí)間段連用，這些動(dòng)詞是：become,begin,buy,borrow,arrive,come,die,fall,finish,gettoknow,go,join,leave,marry等。為了表述這種意思，我們常用相應(yīng)的延續(xù)性動(dòng)詞have，keep等來代替非延續(xù)性動(dòng)詞。--Haveyouhadyourlunchyet?--Yes.Ihadithalfanhourago.-你已經(jīng)吃完午飯了嗎？-是的。我半個(gè)小時(shí)前吃的。

—Howlonghasheworkedasapoliceman?—Hehasworkedasapolicemanfortenyears.-他當(dāng)警察多久了？(work)-十年了。

—HowlonghaveyouknownJack?—Wehaveknowneachother

sincewewereprimaryschoolstudents.-你認(rèn)識(shí)Jack多久了？（know）-我們從小學(xué)就認(rèn)識(shí)了。

1)現(xiàn)在完成時(shí)的特殊疑問句的結(jié)構(gòu)：_______+have/has+主語+過去分詞+其他成分Howlong

與howlong,for或者since搭配使用現(xiàn)在完成時(shí)中的動(dòng)詞有什么特點(diǎn)：A：Howlonghas

當(dāng)用現(xiàn)在完成時(shí)的肯定句和howlong引導(dǎo)的疑問句表示持續(xù)性動(dòng)作和狀態(tài)時(shí)應(yīng)該使用______(持續(xù)性/非持續(xù)性）動(dòng)詞持續(xù)

短暫性動(dòng)詞(come,go,leave,buy…)可

以用于現(xiàn)在完成時(shí)。但不能用于帶有for或是since的肯定句中。HehasleftBeijingforaweek.HehasnotleftBeijingyet.
