分析下面的论证在概念、论证方法、论据及结论等方面的有效性,600字左右。
人口危机的警报已经拉响了,可是人们还没有注意。计划生育的控制人口的做法现在越来越受到质疑,随着女性素质的提高,以及养育成本的飙升,现在的年轻人就会越来越不愿意承担“人口生产”的重任,这对一个国家是致命的。现在女性在提高文化素养的同时,身体素质越来越差,现在生孩子选择了剖宫产,以前那种甚至只靠一个接生婆就可以完成的任务,现在已经成了不可能完成的任务。
一胎化政策导致的独生子女可能不是最优的选择,而且在成长的过程中,独生子女的心理和学习成长都面临很大问题,和以前有兄弟姐妹那样大家庭显然培养出来的人才风险越来越大。一些年逾过百的夫妇,就有一个孩子,谁敢保证这个孩子就能一路健康无事情呢,我们可以看到这样案例,就是中年丧子或者丧女导致整个家庭生活坍塌的悲剧越来越多。生养孩子的成本越来越高,特别是随着越来越多的独生子女结婚后,都不愿意生养孩子。
上海市人口计生委最新出炉的调查显示,上海户籍人口平均生育意愿继续下降,本市户籍人口平均生育意愿为1.07个,与2003年户籍人口生育意愿调查的结果1.17个相比有所下降。目前中国妇女平均的生育水平持续保持在1.5以下,也就是说平均每个育龄妇女生孩子的总数不到1.5个,有专家指出,这是一个极端危险的数字。这意味着,在并不很遥远的未来,中国人口会以平均每30年减少1/4的速度下降。
发达国家的经验表明,人口增长减缓而导致社会负担逐渐加重和劳动成本增加,从而拖累了经济发展。我国现在还在享受人口红利增长带来的好处,但随着人口红利的消失,我们经济增长就可能出现问题。一方面是从劳动力供给上来看,劳动力的锐减导致社会扩大再生产后继乏人,而更重要的是,年轻人越来越少,消费也将面临着沉重问题。事实上,人口控制有一套是人为控制,另外一套是自然控制。自然控制人口的数量是靠饥荒和疾病,当然,自然控制很残酷,但确实自然也在以自己不声不响的方式控制人口数量。
人口越是向城市集中,生养小孩的成本就越高,特别是上学、医疗和买房、结婚。据国家统计局发布的数据,人口可能越来越成为未来30年的一个重大问题,只不过现在大家担忧人口的锐减会影响整个民族的前途。当然,现在逆转控制人口的政策,还为时尚早,但我们必须要提早预防“物极必反”给社会带来沉重打击,修正我们以前过激的做法。
(提示:论证有效性分析的一般要点是:概念特别是核心概念的界定和使用上是否准确并前后一致,有无各种明显的逻辑错误,该论证的论据是否支持结论,论据成立的条件是否充分等。要注意分析的内容深度、逻辑结构和语言表达。)

To what degree can a computer achieve intelligence(智力)? The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet.

If you ran into Smarter Child online, you would be surprised at this kid’s huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season.

He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get stranger answers. A question about Smarter Child’s age returns, “One year, 11 days, 16 hours, 7 minutes, and 47 seconds!” Asking where he lives gets, “In a clean room in a high-tech building in California.”

Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www. intellicast. com.

Some scientists believe that by joining the many systems of the Internet, an artificial being with the combined knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears could be born. However if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I., Artificial Intelligence, he must overcome two problems.

The first is that computers find it difficult to read web pages because the files are labeled in different ways. That’s why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself.

Another problem is that while Smarter Child can process(处理) information more exactly and faster than any human, he lacks common sense—a basic grounding of knowledge that is obvious to any young child.

小题1:From the text we can infer that www. Intellicast. com is a website               .

A.which is specially designed to help Smarter Child

B.where we people can find Smarter Child

C.where weather forecasts are made

D.which is about artificial intelligence小题2: It is probably most difficult for Smarter Child to               .

A.tell us how to spell a difficult word

B.tell us how the American government is run

C.provide us with a famous poem by Shakespeare

D.learn how to tell right behaviors from wrong ones.小题3: Which of the following is TRUE according to the text?

A. Smart Child has his own memory bank big enough for all kinds of information.

B. A. I. Artificial Intelligence is probably the name of a film about a boy-computer.

C. Smart Child can recognize different files and find information needed on his own.

D. We have similar product now which has the knowledge of Einstein, Nixon and Spears.

小题4:Which of the following is the best title for the passage?

A.A New Web Child

B.Smarter Child

C.The Future of Internet

D.Intelligence Development
