?? 例句:?He?will?be?back?in?two?days.他將在兩天后回來(lái)。?
? After常常指以過(guò)去時(shí)間為起點(diǎn)的"在一段時(shí)間之后",所以它常與過(guò)去時(shí)態(tài)連用。當(dāng)aft

There?will?be?more?pollution.將會(huì)有更多的污染。?
辨析:fewer與less?
? Fewer與less分別為few和little的比較級(jí),都意為"更少的"。Fewer與可數(shù)名詞復(fù)數(shù)形式
11、連用,其反義詞為many的比較級(jí)more。?
?less與不可數(shù)名詞連用,其反義詞為much的比較級(jí)more。?
?? 例句:They?buy?fewer?cigarettes?and?less?beer?now.現(xiàn)在他們買的香煙和啤酒少些了。?
