英語(yǔ)四六級(jí)考試是同學(xué)們?cè)诖髮W(xué)里面最關(guān)心的一項(xiàng)考試，備考的過(guò)程中，對(duì)單詞的積累和語(yǔ)法的掌握一定要重視。下面是小編給大家分享的語(yǔ)法知識(shí)，大家可以作為學(xué)習(xí)的參考。

1)倍數(shù)+形容詞/副詞比較級(jí)+than

The girl is ten times cleverer than her brother.

2)倍數(shù)+as+形容詞/副詞/(名詞)+as

His apartment is three times as large as that of mine.
