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。

    The Internet has opened up a whole new online world for us to meet, chat and go where we've never been before. But just as in face to face communication, there are some rules of behavior that should be followed when on line.

    ____ Imagine how you'd feel if you were in the other person's shoes. For anything you're about to send,ask yourself, "Would I say this to the person's face?" If the answer is no, rewrite and reread.____

     If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so. ____ If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.

    ____ Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you license to correct everyone else. ____ At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended. It is not polite to ask others personal questions such as their age, sex and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions.

A. It's natural that there're some people who speak rudely or make mistakes online.

B. Repeat the process till you feel sure that you'd feel comfortable saying the words to the person's face.

C. Everyone was new to the network once.

D. The basic rule is simple: treat others in the same way you would want to be treated.

E. When you send short messages to a person online, you must say something beautiful to hear.

F. You should either ignore the person, or use your chat software to block their messages.

G. If you do decide to tell someone about a mistake, point it out politely.

白蝴蝶之恋

刘白羽

    春意甚浓了,但在北方还是五风十雨,春寒料峭,一阵暖人心意的春风刚刚吹过,又来了一阵冷雨。

    我在草地上走着,忽然,在鲜嫩的春草上看到一只雪白的蝴蝶。蝴蝶给雨水打落在地面上,沾湿的翅膀轻微地簌簌颤动着,张不开。它奄奄一息,即将逝去。它白得像一片小雪花,轻柔纤细,楚楚动人,多么可怜呀!

    她从哪儿来?要飞向哪儿去?我痴痴地望着它。忽然像有一滴圣洁的水滴落在灵魂深处,我的心灵给一道白闪闪的柔软而又强烈的光照亮了。

    我弯下身,小心翼翼地把白蝴蝶捏起来,放在手心里。

    这已经冻僵了的小生灵发蔫了,它的细细的足脚动弹了一下,就歪倒在我的手中。

    我哈着气,送给它一丝温暖,蝴蝶渐渐苏醒过来。它是给刚才那强暴的风雨吓懵了吧?不过,它确实太纤细了。你看,那白茸茸的像透明的薄纱似的翅膀,两根黑色的须向前伸展着,两点黑漆似的眼睛,几只像丝一样细的脚。可是,这纤细的小生灵,它飞出来是为了寻觅什么呢?在这阴晴不定的天气里,它表现出寻求者何等非凡的勇气。

    它活过来了,我竟感到无限的喜悦。

    这时,风过去了,雨也过去了。太阳明亮的光辉照满宇宙,照满人间,一切都那样晶莹,那样明媚,树叶由嫩绿变成深绿了,草地上开满小米粒那样黄的小花朵。我把蝴蝶放在一片盛满阳光的嫩叶上,我向草地上漫步而去了。但我的灵魂里在呐喊,开始像很遥远、很遥远……,我还以为天空中又来了风、来了雨,后来我才知道就在我的心灵深处:你为什么把一个生灵弃置不顾?……于是我折转身又走回去,又走到那株古老婆娑的大树那儿。谁知那只白蝴蝶缓缓地、缓缓地在树叶上蠕动呢!我不惊动它,只静静地看着。阳光闪发着一种淡红色,在那叶片上颤悸、燃烧,于是带来了火、热、光明、生命,雨珠给它晒干了,风沙给它扫净了,那树叶像一片绿玻璃片一样透明、清亮。

    我那美丽的白蝴蝶呀!我那勇敢的白蝴蝶呀!它试了几次,终于一跃而起,展翅飞翔,活泼伶俐地在我周围翩翩飞舞了好一阵,又向清明如洗的空中冉冉飞去,像一片小小的雪花,愈飞愈远,消失不见了。

    这时,一江春水在我心头轻轻地荡漾了一下。在白蝴蝶危难时我怜悯它,可是当它真的自由翱翔而去时我又感到如此失落、怅惘,“唉!人啊人……”

    我默默伫望了一阵,转身继续向青草地走去。
