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。

In the 60s, people asked about your astrological (about star) sign. In the 90s, they want to know your website.   1  Your website is an electronic meeting place for your family, friends and potentially, millions of people around the world. Best of all, you may not have to spend a cent. The web is filled with all kinds of free services and all it takes is some time and creativity.

  2  Like the table of contents of a book or magazine, the home page is the front door. Your site can have one or more pages, depending on how you design it.

While web pages vary greatly in their design and content, most use a traditional magazine layout(版面设计). At the top of the page is a banner(横幅). Next comes a greeting and a short description of the site. Pictures, text, and links to other websites follow.

  3  Think about whom the site is for and what you want to say. Next, gather up the material that you want to put on the site.

While there are no rules you have to follow, there are a few things to keep in mind:   4   If you are too much at the beginning, you may never get the site off the ground. You can always add to your site.

Less is better. Most people don’t like to read a lot of long text online.   55 

Smaller is better. Since it can take a long time to download large image files, keep the file sizes small.

Have the rights. Don’t put any material on your site unless you are sure you can do it legally. Always remember to get the permission from the writer first.

Now it’s time to roll up your sleeves and start building.

A.Start simply.

B.Break it into small pieces.

C.Draw a rough layout on a sheet of paper.

D.Many websites are considered very interesting.E.Before you start building your site, do some planning.

F.Think of your home page as the starting point of your website.

G.These days, having a web address is almost as important as a street address.

2014年8月8日,世界卫生组织将今年3月在几内亚等国家暴发的埃博拉疫情定为“国际突发公共卫生事件”,抗击埃博拉成为世界性联合行动。人们对病毒的认识和斗争是不断前进的。1976年最早暴发埃博拉疫情时人们不知道病毒的来源和传播方式,因此没有有效防制手段;随着研究的深入,现在可以确定病毒来源于动物,人与人主要是通过接触传播,因此主要防止疫情蔓延的办法是把患者隔离,切断传染源,控制疫情;目前尚无有效抗病毒疫苗和治疗药物,防止疫情暴发也无有效办法,人类对该病毒的认识防控还是一个相当长期艰巨的任务。人类要彻底战胜埃博拉病毒,需要准确掌握发生条件、传播方式、研制疫苗等许多步骤,是一个在认识和实践中不断积累经验而逐步实现的过程。现在中美等国医学界正在加紧研究针对该病毒的疫苗。最新消息,美国在非洲感染埃博拉病毒的两位医生在回国接受试验疫苗后,已出院与家人团聚。随着研究的不断深入,相信人类与病毒的斗争会在不远将来最终取得成功。

结合材料,说明人们对埃博拉病毒的研究是如何体现人类认识过程的?
