选B,首先the more后面要加名词medicine.I take是来修饰medicine的,作为定语.接下来是the more的用法:
汉语中表示两个过程按比例同时增加时,用“越……越……”结构.英语中用“the +比较级,the+比较级”结构.这种结构通常从句在前,主句在后,即:第一个the+比较级为状语从句,第二个the+比较级为主句.句型中的连个“the”都是指示副词.两个“the”的后面都必须跟形容词或副词的比较级形式.不过有的语法书中说“第一个the引导的句子是比较状语从句”.
这种结构中的谓语动词一般情况下:主句用将来时态,从句用一般现在时态(代替将来时态).
试比较下列例句的用法:
1.The more,the better.多多益善.
2.The sooner,the better.愈快愈好.
3.The more you learn,the more you wish to leaarn.
你学得越多,你越是想学.
4.The sooner you start,the sooner you will finish.
你开始的越早,你就完成得越快.
5.The more exciting it is,the happier they are.
越是有趣,他们就越是高兴.
6.The more I know him,the more I like him.
我越认识他,就越喜欢他.
7.The more you read,the better you understand.
你看的书越多,你懂得就越多.
8.The hotter the air is,the more quickly it will rise.
空气越热,它就上升得越快.
9.The more learned a man is ,the more modest he usually is.
一个人越有学问,就往往越谦虚.
10.The more you know ,the more you will realize how little you know.
知道得越多,越会体会到自己知道得有限.
注意:
有时这种句型中主句用主谓倒装形式.
例如:
The smaller the house is ,the less will it cost us to heat.
房子越小,花的取暖费就越少.
The more we thought of the lost boy,the more did we get worried.
我们越想那个丢失的孩子,就越是着急.
