【简答题】
Have you ever complained(抱怨) why life is so tiring? Does the sky sometimes seem dark to you? Are your studies sometimes not successful? Well, friends, cheer up and smile all the time. If you see the world with your warm heart, you’ll find that the whole world smiles to you. While in school, sometimes you are tired of your lessons, but have you ever noticed the happy smile on your teacher’s face when you did a good job? One day it is fine. Just before you want to go out, it suddenly starts to rain. Maybe you would feel very sad and start complaining about the weather. But dear friends, why don’t you sit down and listen to the free concert that the nature offers you? And with the timely rain, crops in the fields will grow better and better, so farmers will have a good harvest. Although everyone wants to succeed in what he tries to do, sometimes failure(失败) can’t be avoided. I think failure is not terrible, and the terrible thing is that we are afraid of it and give up hope. When we face failure, we must be confident in ourselves, draw a useful lesson from it and try our best to finish what we have decided to do. As a popular saying goes, “Failure is the mother of success.” Attitude decides everything. With an optimistic(乐观的) attitude life is easy and pleasant. Let’s smile to whatever we meet and the whole world will smile to us. 小题1:What will you find if you see the world with your warm heart? 小题2:Why will farmers have a good harvest according to the passage? 小题3:What is the terrible thing when we face failure? 小题4:How do we make life easy and pleasant? 小题5:What’s the best title of this passage?

举一反三
【单选题】下列关于水活度的叙述正确的是:
A.
最佳水活度与溶剂极性成正比,而最适含水量与溶剂极性大小无关,故采用最适含水量作参数更确切。
B.
非水介质中酶要表现出最大活力,只要有有适当的水活度即可。
C.
各种酶因结构不同,维持酶活性构象的必需水也不同,大部分酶需较高的水活度才表现较好的活力。
D.
获取恒定水活度的方式是向每一溶剂中加入等量的水。

【单选题】患者男,70岁。高血压10年。今在服用降压药物后出现头晕、恶心、乏力。查体:血压110/70mmHg,脉搏106次/min。目前最主要的处理措施是
A.
吸氧
B.
肌注止吐剂
C.
心电监护
D.
加服降压药物
E.
安置头低足高位
【单选题】关于 “水活度”的描述正确的是:
A.
非水介质反应体系中,水活度越大酶活性也越高
B.
非水介质反应体系中,水活度越小酶催化反应速度也越快
C.
水活度是指在特定的温度和压力条件下,反应体系中水的摩尔分数 X w 与水活度系数γ w 的乘积, 溶剂亲水性越大,γ w 越大。
D.
非水介质反应体系中,在最佳水活度值时酶表现出最高活性
