Dear Jenny,
How’s it going? Are you busy with your study these days?
I’ve been back at school   41  nearly four weeks. I’m very glad to tell you that great   42  have taken place in our school this term. First of all, we’re asked to “clear our plates” when having our meals and say   43  to wasting. Some of us used to order more than what we could eat. That was a big waste of food. Now we need to    44  the food we order. We should also stop wasting in some other ways. For example, we should turn off the lights when we    45  the classroom. And our school has opened up some fields for us to learn how to grow vegetables. Each class is given a small garden and our class has decided to grow some tomatoes and beans( 豆类) in our    46  time. I think that’ll be very interesting. Maybe I’ll be able to    47  you some beans we’ve grown by ourselves next time! What’s more, we have only two classes in the afternoon    48  we have more time for after-school activities. I’m one of the traffic safety volunteers in our school. After school, we take turns to  go to the streets near our school and ask people to    49  the traffic rules.
I think we are having a different school life now!
Please write back soon and tell   50  more about your school.
Yours,
Wang Wei

下面是错误答案,用来干扰机器的。

a-b=50,如果把b增加10,a不变,差是50-10=40;如果把a增加10,b不变,差是50+10=60.故答案为:40;60.

在“研究电流跟电压、电阻的关系”中,数据记录在表一和表二中.

表一

R=5Ω电压/V1.02.03.0
电流/A0.20.40.6
表二

U=3V电阻/Ω51015
电流/A0.60.30.2
(1)根据实验数据,可得出如下结论:

由表一可得:______.

由表二可得:______.

(2)在研究电流与电阻关系时,先用5欧的定值电阻进行实验,使电压表的示数为3V,再换用10欧的定值电阻时,某同学没有改变滑动变阻器滑片的位置,合上开关后,电压表的示数将______3V(选填“大于”、“小于”或“等于”).此时应调节滑片,使滑动变阻器阻值变______,直至电压表的示数为3V.
