倍数表达法是历届高考的热点。当我们要表达甲是乙的几倍时，通常可使用以下句型：1.倍数+as+形容词或副词的原级+as+其它。这种结构又常演变成下列两类：倍数+as+many+可数名词复数+as;倍数+as+much+不可数名词+as。如：There are seven times as many people as I expected.是我预料的人数的七倍。There is five times as much coffee in this glass as in that one.这个杯子里的咖啡是那个杯子里的五倍。2.倍数+形容词（或副词）的比较级+ than+其它。如：The hall is five times bigger than our classroom.这个大厅的面积比我们教师大五倍。3.倍数+the size/height/length/width.etc.+of+其它。如：This road is six times the length of that one.这条路是那条路的六倍长。4.计量名词+of+名词+be+倍数+t
