“Mr. Mott often forgets important meetings. The robot will go after him all the time. It listens to everything he says. It sees everything he does. At night, it watches him sleep. It knows everything about Mr. Mott…”
It sounds like a wonderful idea, doesn’t it? But I’m afraid that Mr. Mott will not get on well with the robot, because everyone has something he doesn’t want others know. It is privacy. Just imagine that there is a video camera around you all day. How do you feel? When you are taking an exam, a teacher sits in front of you and watches you all the time. How do you feel?
Mr. Mott doesn’t lose all his memory. At least he remembers that he always forgets. So why can’t he do something for this HIMSELF? He can keep a notebook with him, like most people do. In the notebook he can write down the things he should do, the persons he should meet and the places he should go. Isn’t the notebook much cheaper and safer than the robot?
小题1:“It” in the first paragraph(段落) refers to______________.
A.Mr. MottB.Mrs. MottC.the robotD.a video camera
小题2:Why does the writer think Mr. Mott will not always get on well with the robot?
A.Because it is invented by others.B.Because it can talk with Mr. Mott.
C.Because it can remind(提示;提醒) Mr. Mott of something he forgets.
D.Because it knows something Mr. Mott doesn’t want others know.
小题3:The underlined word “privacy” means _______________in Chinese.
A.提供B.丧失C.特权D.隐私
小题4:Mr. Mott is_____________.
A.handsomeB.forgetfulC.a scientistD.kind and friendly
小题5:From this passage we know that the writer__________________.
A.doesn’t like the robot to follow Mr.Mott all day.
B.thinks it is a good idea to have a robot like Mr Mott’s.
C.If we always forget something important,we should have a robot.
D.A notebook is cheaper than a robot but a robot is better than a notebook.

小云同学在整理厨房时不小心将一瓶醋打翻,醋洒在火炉旁的一堆草木灰上,发现有大量的气泡生成。激发了兴趣,于是他决定与学习小组的同学,对草木灰的成分进行探究。

[探究活动一](1)根据所学酸碱盐知识,同学们猜想草木灰中含有能与酸反应产生气体的盐类物质,于是,设计并进行如下图所示的实验。观察到锥形瓶A内有大量的气泡冒出,试管B中澄清的石灰水变浑浊。根据上述实验现象推断:产生的气体中含有__________,试管B中有关反应的化学方程式为_________________。根据所学知识,可得出如下结论:草木灰中一定含有_________(选填“硫酸盐”、“碳酸盐”或“硝酸盐”)。

[探究活动二] 资料摘要Ⅰ:多种金属化合物在灼烧时,产生的火焰呈现各种特殊的颜色,例如下表。(选填“化合”、“分解”、“置换”、“复分解”)反应。

资料摘要Ⅱ:碳酸钾与碳酸钠、碳酸氢钾与碳酸氢钠的化学性质相似;碳酸氢钠性质不稳定,受热易分解。

(2)同学们认为还必须对草木灰中存在的盐类物质中所含的金属元素进行探究。同学们在老师的指导下,取草木灰样品在火焰上灼烧,透过蓝色钴玻璃片观察到火焰呈________色,由此得出草木灰含有钾元素的结论。

(3)综合上述探究结果,进一步猜测草木灰中含有的钾盐是:a. KHCO3 b.K2CO3c.___________ 的混合物。

(4)小红认为上述猜测_______是错误的。理由是草木灰经柴草燃烧而成,_____________________。

(5)请你写出上述“探究活动一”中,锥形瓶A内发生的一个反应的化学方程式:_________________;简述草木灰的用途之一:_________________。老师指出:草木灰成分复杂,其中所含其它成分的探究有待同学们后续进行。
