如图1所示是自动测定油箱内油量的装置图,其中R′是一个定值电阻,R是滑动变阻器,它的金属滑片P是杠杆的一端,

A是油量表(实际是电流表),电源电压为12V.

当油面达到最高和最低位置时,变阻器的滑片P恰好滑至变阻器的两个端点处.

(1)某次加油后当油面达到最高位置时电流表示数如图2所示.电路中的电流是______A

(2)该装置有这样的缺陷:当油量增大时,油量表的示数却减小.请至少设计一种改进方案,使油量增大时,油量表的示数也增大.

要求:可利用原装置不增加任何部件改装,也可以把油量表(电流表)用其它电表来代替改装.请把你改进的装置简图画在图1下面的方框中.

     July 21st 2007 was a typical English summer's day-it rained for 24 hours! As usual, I rushed home from

work at midday to check on the house. Nothing was amiss. By the time I left work at 5pm. However, the

road into our village was flooded. Our house had never been flooded but, as I opened the front door. a wave

of waters greeted me. Thank God the kids weren't wish me, because the house was 5 feet deep in water. We

lost everything downstairs. And the plaster had to be torn off the wall's ceilings pulled down.

     At first we tried to push on through. We didn't want to move the children out of home, so we camped

upstairs. We put a sheet of plastic across the floor to protect us from the damp. But after three months, we

felt very sick, so we move to a wooden house in a park. The house was small. but at first we were all just

delighted to be in a new place. Unfortunately, things took longer than expected and we were there for 10

months. The life there was inconvenient. What surprised me most was how much I missed being part of a

community (社区). We had lived in a friendly village with good neighbors, and I'd never thought how much

I, I'd miss that.

     Although our situation was very bad, it's difficult to feel too sorry for yourself when you look at what's

happening elsewhere. I watched a news report about floods in Northern India and thought. "We didn't have

a straw hut (茅草房) that was for Christmas. But I can't wait-I'm going to throw a party for our friends in

the village to say thanks for their support. This year, I won't need any gifts-living away from home for months

has made me realize how little we actually need or miss all our possessions. Although we are replacing things,

there's really no rush-we have our home back and that's the main thing.

D. Because some others suffered even more.
