在物理学中，磁场的强弱用磁感应强度（用字母B表示，国际单位是特斯拉，符号是T）来表示，磁感线越密的地方，磁场越强，磁感应强度B越大.

（1）在图20中，甲为某磁极附近磁感线的方向和分布的示意图，由图可知，该磁极为 ▲ 极，若在l处放置一个小磁针，当小磁针静止时，其指向应是图乙中的  ▲   .
（2）磁敏电阻阻值的大小随磁场的强弱变化而变，图丁是某磁敏电阻R的阻值随磁感应强度B变化的图象，据图线可知，磁敏电阻的阻值随磁感应强度B的增大而▲ ．图线没有过坐标原点，说明  ▲  .
（3）王强设计了一个可以测量该磁敏电阻R的电路如图丙所示，（其中磁敏电阻所处的磁场未画出）．将该磁敏电阻R放置在磁场中的位置某处，测出电阻后，利用R—B特性曲线可以读出相应的磁感应强度.
①在图甲磁场中1处，测得的数据如图20表中所示，则该磁敏电阻的测量值为 ▲ Ω. 
②根据该磁敏电阻的R-B特性曲线可知，1处的磁感应强度为   ▲    T.
③在实验过程中，仅将磁敏电阻从1处移至2处，其它条件不变，那么电流表的示数
▲   （填“增大”、“减小”或“不变”）.
④依据上述方法获得的磁感应强度B的测量值与该点实际值存在不小的误差，为尽可能准确反映空间某点磁场的强弱，你认为在选择磁敏电阻时应注意什么问题？

Harvey took the eight umbrellas to the shop and l__(78)__ them there. The shopkeeper said, “They’ll be r__(79)__ tomorrow.”
That evening Harvey went home from the office by bus as he u__(80)__ did. He sat next to an old woman. She had an umbrella on the floor between the s__(81)__. When the bus reached his stop, he picked up her umbrella and stood up.
“Hey!” the woman said, “That umbrella b__(82)__ to me.”
“I’m so sorry.” Harvey said, giving it to her. “Please excuse me for taking your umbrella by m__(83)__.”
The next day he collected the umbrellas from the umbrella shop and got on the bus. As he sat down, a v__(84)__ behind said, “You have certainly had a s__(85)__ day!” He turned around and saw the woman whose umbrella he had almost taken the day before.
