5. x times + n. 通過結(jié)構(gòu)，應(yīng)掌握英語里表示倍數(shù)的表達(dá)句型。
a is x times the size (height, length, width...) of b.
a is x times as big (high, long, wide...) as b.
a is x times + adj.-er than b.
the size (height, length, width...) of a is x times that of b.
the meeting-room is three times the size of our office. = the size of the meeting-room is three times that of our office.
三倍以下通常用double或者twice來表達(dá)兩倍。his weight is double what it was ten years ago. / this railway is twice longer than that one. / the room is twice the size of that one. = this room is twice as big as that one.
