问题 单项选择题

患者,男,50岁。自觉两目模糊,视物不清,伴有头痛,眩晕,舌红少苔,脉细弦。治疗应首选().

A.升麻

B.葛根

C.薄荷

D.柴胡

E.菊花

答案

参考答案:E

解析:此为肝阳上亢所致的目暗昏花,菊花可以疏散风热,平抑肝阳,清肝明目,清热解毒。故选E。【名师点拨】本题考点为菊花和薄荷明目的不同。本题混淆项为薄荷,也能清利头目,疏肝解郁。薄荷的清利头目,主要是指疏散上焦风热,清头目,利咽喉,治疗风热上攻造成的风热头痛,目赤多泪。而菊花微寒清热,人肝经,通过疏散肝经风热、清泄肝热、平抑肝阳来治疗目赤昏花之证。本题中"头痛、眩晕"表明了肝阳上亢的病机,所以选E。答题的时候,一定要注意题干,中间包含的信息和提示要能领悟到。另外,对于相似功效的中药间的比较,要理解其机制。如果本题的兼证变为肝郁气滞的症状,那么就要选薄荷了。要学会举一反三的对待一个题目。

"But Ijust paid 1.69 for this bottle of wine last week.How is it that the price is 2.25?"

There are at least three things going on that have caused the price of wine to rise.All haveto do with the supply and demand factors of economics.

The first factor is that people are drinking more wine than ever before.This demand formore wine has increased wine sales in America at the rate of 15 percent a year.

The second factor is that the supply of wine has stayed relatively the same, which meansthat the same number of bottles is produced each year.Wine producers are trying to open upnew land to grow more grapes.But in at least three wine producing areas of the world-France,Germany, and California --- new vineyards(葡萄园)will not be useable in the near future.Wines are produced in other countries, such as Italy, Spain, and Portugal, as well as Argentine,Australia, Austria, and Chile.And these wines will be seen more often on the American market.But none of these countries will be able to fill the good wines.

The third factor is that costs of wine production are soaring.The workers who make wineare asking for more money, and the machinery needed to press the grapes is becoming moreexpensive.

When the demand for something is greater than the supply, prices go up.When productioncosts, meaning the price of labor and machinery rise, the producer adds this increase to theprice of the wine.For these reasons, that bottle of wine now costs 2.25 instead of 1.69.
