储液罐打有“IN”钢印的管接头为储液罐（）接头。

为了测量一个量程为3.0V电压表的内阻Rv（约几千欧），某同学采用了如图所示的电路，利用“半偏法”进行测量，电路中电阻箱R₀的最大阻值为9999Ω，滑动变阻器R的最大阻值为50Ω．

①按图示电路将所给的实物连成测量电路．

②该同学测量电压表的内阻时，实验步骤为：

A．将电阻箱R₀的阻值调到零

B．闭合开关S

C．连接好电路，注意断开开关S

D．把滑动变阻器R的滑片P滑到b端

E．调节电阻箱R₀的阻值，使电压表的示数为2.0V

F．调节滑动变阻器R，使电压表的示数为3.0V

G．记下此时电阻箱R₀的阻值

以上实验步骤合理的顺序为______

③若所记电阻箱R₀的阻值为3500Ω，则用此法测得的电压表内阻是______kΩ，比其真实值______（填“偏大”、“偏小”或“相等”）．

I moved to this small town at the age of twelve．After getting  36   in our new house and starting school，I began to explore the   37  area．I was exploring the pond when I discovered the fish．

There were two of them，one about a foot long，  38  the other just a little smaller，and they were the most beautiful fish I had  39  seen．They had blue and yellow and red  40  from head to tail．Before they saw me，they swam  41  over the sand just under the front edge of the large cedar(杉)tree which had long before fallen  42   the pond．

I went back the next day after school  43   with about six feet of fishing line and a hook borrowed from our elderly neighbor．and half a dozen worms I had   44  out of the garden．We did not own any fishing tool，and   45  a city kid，my fishing experience, had  46  week long visits to my relatives．

I took a shortcut  47  some fallen cedars on my way to the pond．As I was climbing over one tree and ducking under another，I  _48  my footing，and my soup can of worms went flying into the air．My  49   was only increased when I noticed that my worms had disappeared．

I went to the pond，looked down again，and there they were．I made a few  50   to catch them by hand，but I soon realized it was never going to  51 ．I had been trying to catch them for quite a while without actually even  52   either one．After each attempt，they   53  suddenly go around the pool，then settle back under the log．They could really go  54 ，but they were just too fast to be caught．I was wet and   55   and it was time to go home．
