倍數(shù)用times來表示，英語中“倍數(shù)”的表達法主要有下列幾種：

(1)如果要表示“A正好是B的多少倍”可用:

①A+謂語+倍數(shù)+as+形容詞/副詞(原級)+as+B;

②A+謂語+倍數(shù)+the size/length, weight, height, width, age, price…+of B。例如：

注意：此句型中用比較級時，倍數(shù)要減去原來的底數(shù)，“是……的4倍”等于“比……大3倍”。

(3)若表達“這條鐵路是那條鐵路的8倍長”。有以下幾種：

This railway is eight times as long as that one.

=This railway is eight times the length of that one.

=This railway is seven times longer than that one.

The manager declared the meeting open. 經(jīng)理宣布會議開始。

They declared him to be the winner. 他們宣布他為獲勝者。

14. Therefore, go down on your knees and beg the Duke for mercy. 因此，快去跪下請求公爵寬恕你吧。

(1)therefore作副詞，意為“因此”，表示結(jié)果或理由，相當(dāng)于as a result of that;它不能引導(dǎo)從句,不要把它當(dāng)連詞來用。therefore常常和and一起使用，這時therefore前可用逗號或者不用標點符號；如果不與and連用，therefore前用分號。例如：
