2010年1月24日至25日农历腊月二十九和除夕（）到井冈山慰问革命老区干部群众。A

阅读理解。

     Middle school students have far too much homework. They usually have to sit up three or four hours

every night doing their homework. Now one school in my hometown has made a rule of limiting (限制)

homework. The homework is limited to an hour a day and the students have no homework on the weekend.

I think this is an excellent idea that will allow students to live better and healthier lives.

     Less homework will give students more time to enjoy other pastimes (休闲活动). I have many books

which I received as gifts from my parents and friends. They have been kept there on my shelf for several

years! Because of homework, I will have not read a single one of them. With less homework, students will

be freer to develop their interests in art, music and other hobbies.

     More time free from homework will get our physical health better. Many students like sports, but they

have little time to play football, basketball, volleyball and so on. They hardly have time to have a trip or take

part in any social activities. They must spend so much time solving math problems and doing grammar

exercises. Besides, staying up late to finish their homework leaves many students exhausted in the morning.

Not getting enough sleep is not only unpleasant; it also makes students more likely (有可能得) to get colds

and other illnesses.

小明同学在“测定小灯泡的功率”实验中，所用电源电压为4.5V、7.5V和9V中的一个，滑动变阻器上标有”20Ω  2A”字样，小灯泡标有“4.5V”字样，估计小灯泡的额定功率约为1.5W左右，由此可估计小灯泡正常工作时的电流约为_____A．他按图连接好电路，先将变阻器的滑片移至______端（选填“A”或“B”），然后闭合电键S，再移动变阻器的滑片P，观察到小灯泡发光逐渐变_______（选填“亮”或“暗”）．当小灯泡正常发光时，变阻器的滑片P恰好在中点上（即连入电路的电阻为10Ω），此时变阻器两端的电压约为____________V．由此可推知小华所用的电源电压为_____V，小灯泡的额定功率为_______W．
