现在的产量是十年前的三倍。 5. 倍数+more+名词+than+其它。如: There are nine times more books in his bag than in yours. 他书包里的书比你书包里的书多九倍。 6. 其它表达。如: She's twice/double my age. 她的年龄是我的两倍。 The average income of the staff has been increased by 50 percent compared with last year. 与去年相比,该单位职工的收入已增加了50%。 He runs faster than me by three times. 他跑得比我快三倍。 【考查方向】 1)倍数在句中的位置一般放在第一个as前面或比较级前面或名词前面。 2)用times表示倍数时,一般只限于表示包括基数在内的三倍或三倍以上的数。表示两倍可以用twice或double,一倍用once. 【重点归纳】 除了我们初中所学的形容词的比较级的用法,本模块我们主要归纳几种句式结 (一)含倍数的比较句型 1. 倍数+as+形容词原级+as…。如: This bridge is three times as long as that one. His room is twice as big as mine;in other words,mine is only half as big as his. 【特别提醒】 “as…as”中间加入名词的句式: ●倍数+as+形容词+a/an+可数名词单数+as… ●倍数+as+形容词+可数名词复数/不可数名词+as…。如: Last year my brother twice as big a new house as mine. He has collected more than three times as many stamps as I (have). I spent twice as much time on my studies as you did. 【难点点拨】 该结构的省略:通常省略形容词后面的名词及比较的部分。如: I have to transfer(转乘)buses so I spend twice as much (money as others)for the bus every day. 2. 倍数+形容词比较级+than…。如: This street is four times shorter than that one. Fear of danger is ten thousand times more terrifying than danger itself. 【特别提醒】 倍数+形容词比较级+名词+than…。如: He earns five times more money now than he did ten years ago. There are three times more books in our library than in yours. 3. 另外,请注意下面两种说法: (1) 倍数+what从句。如: The length of the road is four times what it was three years ago. (2) 倍数+that of+被比较对象。如: Airmail charges almost twice or three times that of a normal mail. (二)其它句式 1. "比较级+and+比较级"表示"越来越…"。如: Things are getting better and better every day. Our country is becoming more and more beautiful. 2. "the+比较级…,the+比较级…"表示“越…,就越…”。如: The more you have, the more you want. The more a man knows, the less he knows he knows. 【知识扩展】 在形容词比较级前可以加a little, a bit, a lot, no, any, much, far, even,still等副词组表示程度的加深。如: The result is much better than we expected. Actually, health is far more important than wealth. 编辑:小暖 来源:网络返回搜狐,查看更多 |
