问题 单项选择题 A1/A2型题

血肌酐多用下列何种方法测定()。

A.尿素酶法

B.Jaffe动力学法

C.二乙酰-肟法

D.磷钨酸还原法

E.尿酸酶法

答案

参考答案:B

解析:Jaffe动力学法基于肌酐和非肌酐色原在反应速度上的差异,即后者与苦味酸发生反应比前者要慢,利用这一点来避开非特异反应的干扰(但不能根本消除)。此法干扰和影响因素较少,速度快,适用于自动分析,近年已被普遍采用。

阅读理解

请阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该选项的标号涂黑。

Sitting on the peaceful coast of Galapagos Islands. Ecuador, watching the sun move quietly into the sea, you shouldn’t forget that Charles Darwin (1809-1882) arrived here in 1835. He stayed on the islands for five weeks, observing various animals. This finally inspired (启发) his famous work, On the Origin of Species. You can certainly follow Darwin’s footsteps and enjoy a trip from four to seven days to the islands.

The most well-known animals of the Galapagos is the giant tortoise(巨型海龟),which can be seen moving slowly around the highlands of Santa Cruz, the second largest island in the archipelago (群岛). Some of these creatures are so old that they might have been in their youth by Darwin himself.

Despite strict control over activities and timing, your stay on the Galapagos will be remembered as a chain of incomparable pictures; diving with sea lions that swim and play within inches of you; feeling small sharks touch your feet as you swim; and most magically, seeing a whale and her baby surface with a great breath of air.

Travelling between the islands and observing the wildlife that so inspired Darwin, so you will feel as though you are getting a special view of an untouched world. At night you will sleep on board the ship, leaving the wildlife in complete occupation of the islands, which are as undisturbed now as they have been since the beginning of time.
