根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    Writing an article for your school newspaper can be exciting and rewarding, especially when you proudly see your name in print.

    Decide on a topic. {#blank#}1{#/blank#} If you plan to write a news article for a monthly newspaper, you will need to take into consideration whether the topic will be relevant before printing. To get ideas for stories, listen to your fellow students and find out what has them talking. Follow developments within your school and community to get information on what would interest your readers.

    Do your research. There is an old saying in law that a good lawyer never asks a question that they don't know the answer to. {#blank#}2{#/blank#} To sum up, the more, the better.

    Attract the readers with a lead. As the beginning of a newspaper story, a lead has to be direct, but it does not mean you don't need to entertain the reader as well. {#blank#}3{#/blank#} Your lead must be short, but it must also state as many of the essential parts of you story as possible.

    Consider the 5 Ws and H. These are the meat and potatoes of your news articles. You article must answer all of these questions: Who, What, When, Where, Why and How. Once you have answered these things, you can feel confident. {#blank#}4{#/blank#}

    Write, edit, rewrite and repeat as necessary. So, much about having a successful final product is about being willing to spend time and effort in editing and reviewing process. {#blank#}5{#/blank#} After that, make changes as a result. Having taken some useful suggestions, you are to make your article readable not only for their content, but also for their quality.

如图所示,Q1、Q2为两个等量同种的正点电荷,在Q1、Q2产生的电场中有M、N和O三点,其中M和O在Q1、Q2的连线上(O为连线的中点),N为过O点的垂线上的一点。则下列说法中正确的是()
A.M点的电场强度比N点小
B.若将一个正点电荷分别放在M、N和O三点,则该点电荷在M点时电势能最大
C.若ON间的电势差为U,ON间的距离为d,则N点的场强为
D.若ON间的电势差为U,将点电荷-q从N点移到O点,需克服电场力做功qU

某金属板M受到某种紫外线照射时会不停地发射电子,射出的电子具有不同的方向,其速度大小也不相同。在M旁放置一个金属网N。如果用导线将MN连接起来,M射出的电子落到N上便会沿导线返回M,从而形成电流。现在不把M、N直接相连,而如图所示在M、N之间加一个电压U,发现当U>12.5V时电流表中就没有电流。问:被这种紫外线照射出的电子,最大速度是多少?(已知电子质量me=0.91×10-30kg)
