Have you ever wondered whether writing and maintaining your business blog is a waste of time If you have, it probably is. Business blogs are valuable for some companies, but for many blogging takes up time and resources better spent elsewhere. If any of the following statements apply to you, stop posting to your blog (or re-purpose what you would have posted) and start doing something more productive:

(41)

You dread writing another post.

Either way, whatever you publish will not represent your business well, so why do it Any time you feel you can’t put your best foot forward, don’t take the step.

(42)

Your page views are stagnant.

Unless of course you can accurately identify tangible benefits from that readership.

(43)

You can’t quantify your return.

Blogging is like any other investment in time and resources: If you don’t see a return, don’t do it.

(44)

Your goal is to provide valuable resources to customers.

Potential customers who gladly read resource pages often run screaming from the same information when it appears on a blog.

(45)

Your readers are not your customers.

Building an audience is useful only if the audience contains current and potential customers. Know who is reading your biog. If you can’t be bothered to find out, that’s yet another indication it’s time to stop.

[A] Many business owners say, "I don’t have any numbers to back it up, but I know my blog is paying off." Really How If your blog isn’t sending significant traffic to your website via search engines, isn’t directly generating sales, doesn’t create a community, or creates a community that doesn’t actually

benefit your business, your blog isn’t paying off.

[B] If you aren’t excited by the thought of sitting down to write your next post, you have nothing to say and will once again borrow ideas from another blog, or already realize blogging is a waste of time but won’t admit it.

[C] Great goal. By all means do it. But don’t put how-to information, or useful tips, or non-news information on your blog. Many people are blog-averse because most blogs are terrible, so your blog may automatically get painted with the same brush. If your material is relatively evergreen, create resource pages on your website instead.

[D] When new posts average the same number of page views, and on a monthly basis so does your entire blog, you’ve stalled. Maybe loyal readers keep returning, or maybe you gain some and lose some, but either way not much is happening. A blog with a small stagnant readership is a blog that is a waste of time, at least for business purposes.

[E] Never blog because you think it helps; you have to know. Knowing takes effort. If you’re not willing to put the time you need into tracking and analyzing data, you’re either lazy or afraid to find out you’re wasting your time on your blog. Sometimes quitting is more admirable than staying the course.

[F] This happens more often than you think. For example, a friend is an incredibly successful financial planner. He writes a blog that gets thousands of unique visitors a month. But he writes about topics of interest only to other financial planners. That would be fine if his blog generated media opportunities, or supported a book he plans to write, or helps him network and bring in more business—but it doesn’t.

阅读下面文字,完成文后五题。
有科学家认为,由父母选择基因“组合”下一代的时代已快来临了。在“组合”未来的“非常婴儿”方面,父母们面对的是一道多项选择题,他们可以选择让婴儿能抵抗常见疾病和感染的基因,这样婴儿不会再害怕癌症、心脏病等;父母让孩子的个子长高一点、头发浓密一点也并非难事。
在美国的普林斯顿,科学家们成功地利用基因改善了老鼠的大脑功能,经过“加工”的老鼠比其他普通老鼠明显聪明得多。这种神奇的效果来自于从外界植入老鼠体内的一种基因,这种基因产生名为NR2B的化学物质。人脑当然比老鼠的大脑复杂得多,但它们的工作原理实际上是一样的。
至于说到为孩子选择人格与个性,其实也不是匪夷所思的,专家相信,个人个性的特点中至少有一半是由基因的特性决定的。
科学家打算将来自不同个体的基因:比如聪明一些的迟钝一些的,好看的和普通的,混合在一起进行研究,以便了解为什么人们会在力量、耐力、敏捷性等方面有差异。当这些主管天赋与性格的基因的奥秘解开之后,未来的父母就离“设计”自己的孩子又近了一步。但技术上的难题是,人为注入的基因大部分都是人体内自有的,因此如何确保这些外来基因能发挥作用,取代原有的基因是个关键。
有专家对基因工程能否如人们所认为的那样大步向前跃进持怀疑态度,因为在基因和染色体的世界里,随机性因素很多,基因一旦站错了队,不仅不能发挥出人们预先估计的作用,反而会给别的重要基因带来影响,甚至破坏它们。
要想给人的自然基因“升级”,只有通过“人造染色体”,可是人的染色体数目的标准是23对,加进人造染色体后,就必然引起染色体数量上的变化,如果未来人类还遵循有性繁殖规律的话,这些多出来的染色体还会传给下一代,这会带来什么后果多出来的染色体怎么办就是世界一流的科学家现在也无法对这些问题作出明确回答。

下面对文章内容理解正确的一项是:

A.通过选择基因来“组合”下一代的研究还只是一个设想。

B.通过选择基因“组合”一个“非常婴儿”这个问题还需要进一步研究探索。

C.科学家们的实验研究表明,由基因产生的名为NR2B的化学物质可以使人脑变得更聪明。

D.目前,世界一流的科学家尚无法解决多余染色体会给下一代带来什么后果和处理多余染色体的问题。
