在“练习使用多用电表”的实验中．

①用多用电表测量某电阻，将档位旋钮调至“×10”档，读数时发现指针偏转角太大，为使测量结果更加准确，则应改用____档．（选填字母代号即可）

A．×1        B．×100        C．×1000

②多用电表使用时间长了，其内阻会明显变大．继续使用该表测电阻时，通过使用“调零旋钮”进行调零仍能使用，假设调零前后电池的电动势不变，则调零后用该表测得的电阻值与电阻的真实值相比，将____．（选填字母代号即可）

A．偏大         B．偏小        C．不变

根据短文理解完成下列各题。

    Denzil wasn't a very clever donkey. He always did some silly things because he didn't think. "Look out," the other donkeys said. "Here comes Denzil—everybody runs away!"

    One day, Denzil carried two heavy bags of salt, one on each side of his back. When he was crossing a big river, he fell into the water. The salt began to melt. When he tried his best to stand up, all the salt was gone. "Hey, that's really great," thought Denzil. "I must remember that. Next time I can do it again when I'm crossing a river."

    The next time he carried two bags of cotton(棉花). "Watch this, everybody," said Denzil when he and his friends got to the middle of the river. He went into the water and was gone! Nobody told him that cotton could get heavier in water. The other donkeys pulled him out at once and luckily he was still alive.
