       Never try to work when you are very hungry. If you decide to do your homework right after school,
you may get something to eat before getting to work. Always do your homework before you get too tired.
Don't wait until very late in the evening, or your work will seem much harder than it really is.
       If you have more than an hour's work, give yourself a break after an hour. On the other hand, don't
break it up so much that you can't get anything done you should be able to work at least a half at a time
without stopping. 
       Don't put it off until the last minute. If you put off doing your homework, you will have it on your
mind, and you won't enjoy your free time so much. If you put it off until the end of the week or until right
before a test, you will have too much catching up to do. A little bit each night enough to keep up with what
is happening
each day in school, will take the fear out of tests and keep you on top of it all. 
       Do your homework at the same time every evening. This will help you make it a habit. It will make it
easier to do and it will make your free time more enjoyable, as well.
1. If we wait very late in the evening, our work will _______.

吴毅强同学在探究“串联电路各电压的关系”时,分别按如图甲、乙、丙三个测量电路进行了正确的测量,测量结果U1、U1、U3如下表所示。

(1)吴毅强同学分析数据后发现:串联电路各部分电压之和很接近但小于总电压。这与他们猜想的“串联电路各部分电压之和等于总电压”不完全一致。为此,他重新检查实验电路,再进行了两次测量,测量数据基本没有变化。老师提示:电压表接入电路测量时本身会对电路结构有影响。请你帮他重新设计测量电路图,把它画在下边的虚线方框中。

(2)该同学按照你设计的测量电路正确进行测量,验证了他们的猜想。但他们同时发现: “串联各部分电压是相等的”。这个结论一定成立吗?___________(选填“一定”或“不一定”)。为了检验这个结论是否成立,应该______________继续进行实验。

(3)根据表中数据,可以求得电压表内阻Rv与灯泡电阻RL的比值是___________。

(4)吴毅强同学认为,即使按重新设计的测量电路测量,电压表同样会改变电路结构,因而也会影响各电压的测量值,但不会影响实验结论的正确性。你认为会影响实验结论的正确性吗? _________(选填“会”或“不会”)。
