现准备用“伏安法”测量额定电压为2.5V的小灯泡的电阻，实验室能提供的实验器材有：

A．待测小灯光L（其正常工作时的电阻值约为10Ω）；

B．二节新的干电池串联（每节干电池的电压为1.5V）；

C．电压表一个（量程为0～3V，0～15V，电阻为5KΩ）；

D．电流表一个（量程为0～0.6A，0～3A，电阻为5Ω）；

E．滑动变阻器R₀（阻值为0～50Ω，额定电流为1A）；

F．开关S一个，导线若干。则：

（1）如果使用上述器材来测量小灯泡的电阻，那么，当小灯泡正常工作时，该电路中的电流约为___________A，因此，电流表的量程应选0～ _____________A。

（2）由于电流表和电压表都有一定的电阻，严格来说将它们接入电路后，对电路都要产生一定的影响。那么，为了减少误差，在甲、乙所示的电路图（未画完）中，最好选 _____________（选填“甲”或“乙”）。

（3）根据以上选择的电路图，在丙图中用铅笔画线代替导线进行连线，使之成为能比较精确地测量出小灯泡电阻的电路（其中，部分导线已连接）。

（4）在实验中，某同学设计的实验报告及实验记录数据如下表所示。

①将实验步骤中的空格填写完整。

②从实验记录中可以看出，存在明显错误的记录数字是__________________。

③根据实验记录数据，采用“描点法”在如图所示的坐标系中，作出小灯泡的U-I图像。

- Thank God you’re safe!

A. in time

B. in case

C. in need

D. in vain

In all one’s lifetime it is oneself that one spends the most time being with or dealing with. But it is exactly oneself that one has the least understanding of.

When you are going upwards in life you tend to overestimate yourself. It seems that everything you seek for is within your reach. When you are going downhill you tend to underestimate yourself, mistaking difficulties for your own incompetence.

To get a thorough understanding of oneself is to gain a correct view of oneself-aware of both one’s strengths and shortages. You may look forward hopefully to the future but be sure not to expect too much, for ideals can never be fully realized. You may be courageous to meet challenges but it should be clear to you where to direct your efforts. That’s to say so long as you have a perfect knowledge of yourself there won’t be difficulties you can’t overcome.

To get a thorough understanding of oneself needs self-appreciation. Whether you think you are a towering tree or a blade of grass, a high mountain or a small stone, you represent a state of nature that has its own value. If you earnestly admire yourself you’ll have a real sense of self-appreciation, which will give you confidence. As soon as you gain full confidence in yourself, you’ll be enabled to fight and overcome any adversity.

To get a thorough understanding of oneself also requires doing oneself a favor when it’s needed. In time of sadness, do yourself a favor by sharing it with your friends so as to change a gloomy mood into a cheerful one; in time of tiredness, do yourself a favor by getting a good sleep. As you are aware, what a person physically has is but a human body that’s vulnerable when exposed to the elements. So if you fall ill, it’s up to you to take a good care of yourself.

In a word, to get a thorough understanding of oneself is to get a full control of one’s life. Then one will find one’s life full of color and flavor.
