问题 单项选择题

组织制定和公布直接接触药品的包装材料和容器的药用要求与标准的部门是( )

A.市(地)级药品监督管理机构
B.国务院工商行政管理部门
C.省级人民政府药品监督管理部门
D.省级人民政府工商行政管理部门
E.国务院药品监督管理部门

答案

参考答案:E

解析:首先要确定药品的包装材料和容器的批准部门为国务院药品监督管理部门,因为药品包装是随同新药报批材料一同上报批准的,所以直接接触药品的包装材料和容器其药用要求与标准均为国务院药品监督管理部门批准,故答案为C。

Soon computers and other machines will be able to remember you by looking at your eyes! The programme works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.

The eye-recognition(眼睛识别) programme is already being tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon, this technology will take the place of all other ways of finding out who people are.

However, scientists are working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.

Eye-recognition is better than other kinds because your eyes don’t change as you get older, or get dirty like hands or fingers. And even twins have different eyes, so the programme can be up to 94% correct, depending on(依靠) how good the technology is. Some programmes may only be right 51% of the time. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.

In the future your computure will be looking at you in the eye. So smile!

小题1: How does the eye-recognition programme work?

A.You write your number.

B.You show your ID card.

C.You look at the machine.

D.You say your name.小题2: Why can the programme be up to 94% correct?

A.Because eyes never change.

B.Because hands or fingers can get dirty.

C.Because people like the idea of the programme.

D.Because the programme is widely used around the world.小题3: Which of the following is TRUE?

A.The programme is being tested in Japan.

B.Machines with other systems can also tell who you are.

C.91% people like the idea of the programme.

D.Computers can remember you by looking at your clothes.小题4: What does Paragraph 4 talk about?

A.Introduction to other kinds of programmes.

B.Advantages of the programme.

C.The places where the programme is tested.

D.The way how the programme works.

实验题

过氧化氢是重要的氧化剂、还原剂,它的水溶液又称为双氧水,常用作消毒、杀菌、漂白等。某化学兴趣小组取一定量的过氧化氢溶液,准确测定了过氧化氢的含量,并探究了过氧化氢的性质。

Ⅰ.测定过氧化氢的含量请填写下列空白:

(1)移取10.00 m密度为ρ g/mL的过氧化氢溶液至250mL_______(填仪器名称)中,加水衡释至刻度,摇匀。移取稀释后的过氧化氢溶液25.00mL至锥形瓶中,加入稀硫酸酸化,用蒸馏水稀释,作被测试样。

(2)用高锰酸钾标准溶液滴定被测试样,其反应的离子方程式如下,请将相关物质的化学计量数及化学式填写在横线上。

____MnO4-+____H2O2+____H+=____Mn2++____H2O+________

(3)滴定时,将高锰酸钾标准溶液注入______(填“酸式”或“碱式”)滴定管中。滴定到达终点的现象是________________。

(4)反复滴定三次,平均耗用c mol/L KMnO4标准溶液V mL,则原过氧化氢溶液中过氧化氢的质量分数

为____________。

(5)若滴定前滴定管尖嘴中有气泡,滴定后气泡消失,则测定结果________(填“偏高”或“偏低”或“不变”)。

Ⅱ.探究过氧化氢的性质该化学举小组根据所提供的实验条件设计了两个实验,分别证明了过氧化氢的氧化性和不稳定性。(实验条件:试剂只有过氧化氢溶液、氯水、碘化钾演粉溶液、饱和硫化氢溶液,实验仪器及用品可自选。)请将他们的实验方法和实验现象填入下表

(6)
