答案

参考答案:领导的具体含义包括:

(1)领导是领导人对组织成员和组织整体的活动发挥影响的过程;

(2)领导只能在领导人和被领导人的关系中存在。领导的有效性和稳定性取决于被领导人的认可程度。另一方面,组织成员的认可和赞同使组织的领导合法化;

(3)领导过程是为实现特定组织目标的过程。在这种组织目标中,还包括为实现这一目标的一切组织任务。不同的组织目标和组织任务需要不同的组织领导;

(4)领导过程包括正式的和非正式的领导过程;

(5)领导过程的具体情况包括:组织成员之间的关系结构、组织的性质、组织的文化环境、制约组织活动的其他各种条件等。

实验题

某校研究性学习小组拟利用分光光度法对空气中二氧化硫含量(mg/m3)进行测定。分光光度法则是通过测定被测物质在特定波长时光的吸收度,对该物质进行定性和定量分析。其工作原理可以简单的用公式表示为A=kc,其中A为吸光度,k为一定条件下的常数,c为溶液浓度。

实验步骤如下:

⑴ 采样:

① 如果你是该小组成员,你对采样的地点和时间有何建议:   

② 用右图装置采样,通过50L空气后,将吸收液移入100ml容量瓶,用少量吸

收液分两次洗涤吸收装置,合并洗涤液于容量瓶中,定容备用。用多孔球泡而不

用导管的原因是   

⑵ 吸光度与SO2含量标准曲线的绘制:在6支25ml比色管中,用每毫升含25μg

二氧化硫的标准液配置下表标准SO2含量系列。

二氧化硫标准系列

管 号012345
标准液(ml)00.200.400.600.801.00
吸收液(ml)10.009.809.609.409.209.00
二氧化硫含量(μg)05.0010.0015.0020.0025.00
用10mL比色皿,以水为参比,测定各管吸光度,实验结果如下。

管 号012345
吸光度00.200.400.600.801.00
请在右图所示的坐标系中绘制标准曲线:

⑶ 准确量取容量瓶中溶液10mL加入比色皿,测得其吸光度值

为0.10,则空气中二氧化硫含量为   mg/m3。我国环境空气

质量标准中对每次空气质量测定中SO2的最高浓度限值(mg/m3):

一级标准:0.15;二级标准:0.50;三级标准:0.70。

则该市空气为   级标准。

⑷ 甲、乙两组同学测定结果相差较大,乙组同学测定空气中SO2

含量偏小,试分析乙组同学出现误差的可能原因:   (两个所用

药品和装置均无问题)。

The quest for success always begins with a target. As Berra once said, “You got to be very careful if you don't know where you're going, because you might not get there.”

Too many people wander through life like sleepwalkers.Each day they follow familiar routines, never asking, “What am I doing with my life?” and they don’t know what they’re doing because they lack goals.

Goal-setting is a focusing of the will to move in a certain direction.Begin with a clear conception of what you want.Write down your goals and date them—putting them into words clarifies them.Rather than concentrating on objects to acquire and possess, focus on fulfilling your desires to do, to produce, to contribute—goal-setting that yields the true sense of satisfaction we all need.

It’s important to visualize(想象)yourself accomplishing your goal.While losers visualize the penalties(不利)of failure, winners visualize the rewards of success.I’ve seen it among athletes, statistics contrasting air and highway safety, but it made no difference.I had read too many articles describing crash scenes and imagined these scenes vividly.I had programmed myself, without realizing it, to stay off planes.

Then one summer I had the opportunity to fly on a private plane with friends to a resort;I didn’t want to miss out on a great vacation.So I spent two weeks imagining a smooth flight on a beautiful sunny day and an easy landing.

When the day arrived, I was eager to go.To everyone’s surprise, I got on the plane and I loved every minute of it, and I still use the techniques I employed that day.

D.he wanted to take a private plane instead of a public one小题4:What would be the best title for this passage?

A.Define Your Coal

B.Visualize Rewards of Success

C.Overcome the Fear of Air Travel

D.Sleepwalking Through Life
