小阳同学探究小灯泡发光时的亮度与哪些因素有关．他用九只不同规格的小灯泡分别接入电路，使它们都正常发光，并用电压表和电流表分别测得小灯泡正常发光时的电压和电流．小阳仔细观察小灯泡的亮暗程度，发现可把九只小灯泡分成三组，每组的亮暗程度相同，且第一组最亮，第二组较暗，第三组最暗．实验中记录的有关数据如下表所示．

分组	第一组			第二组			第三组
序号	1	2	3	4	5	6	7	8	9
U/V	6	12	15	6	12	15	3	6	15
I/A	2.0	1.0	0.8	1.0	0.5	0.4	1.0	0.5	0.2
亮暗	最亮			较暗			最暗
U•I/V•A	12	12	12	6	6	6	3	3	3

（1）分析比较实验序号1、4、8与3、6、9的数据及观察到的现象，可得到的初步结论是：小灯泡两端电压相同时，______．

（2）分析比较实验序号______的数据及观察到的现象，可得出的初步结论是：通过小灯泡的电流相同时，小灯泡两端的电压越大，灯越亮．

（3）综合分析比较表中的数据及观察到的现象，可得到的初步结论是：______．

请仔细阅读下题五位人员的个人情况说明，从A-F中选出能解决他们问题的恰当建议。（有1个多余选项）（共5小题，计5分） I. Students’ problems 小题1:My mother is a doctor. She is too busy with her work to spend the weekends with me.
