题目内容

【题目】2010年11月1日零时,我国进行了新中国成立以来的第六次全国人口普查,此次普查的主要目的是查清十年来我国人口的数量、结构、分布和居住环境等方面的变化情况,为实施可持续发展战略,提供科学准确的统计信息支持。读有关材料,回答问题。

材料一:第六次全国人口普查主要数据于2011年4月28日发布。此次人口普查登记的全国总人口为1339724852人。比2000年第五次人口普查相比,10年增加7390万人。

材料二:目前我国超过60岁的老年人为1776亿,约占总人口的1326%,未来五年将是人口老年化加速发展期,城乡老年空巢家庭比例不断上升,人口将呈现老年化、高龄化、空巢化加速发展的新特征。

1人口普查不能弄清

A人口数量 B人口构成

C人口合理容量 D城市化水平

2材料一和材料二说明我国当前面临的主要人口问题为_______;_______

3材料二表明,人口老龄化、高龄化对社会经济发展的影响_______;_______

4面对日益严重的老龄化、高龄化问题,我国已经放宽生育控制,实施单独二胎政策,对此,你是否赞成?理由是什么?

【答案】

1C

2人口基数大,数量增长快; 人口老龄化

3社会赡养费用上升,政府财政压力增大;青壮年社会负担过重;

4赞成。可以减轻青壮年的社会负担;

不赞成。我国人口基数大,人口增长仍很快,将进一步加大人口与资源、环境之间的压力。

【解析】

试题分析:

1人口普查可以反映人口数量的多少,人口年龄和性别结构,城市人口和乡村人口的比重。人口合理容量:指一个国家或地区最适宜的人口数量,由资源状况、对外开放程度、消费水平等因素制约。人口普查不能弄清人口合理容量,故选C。

2由材料一可知,第六次全国人口普查全国总人口为1339724852人。比2000年第五次人口普查相比,10年增加7390万人。说明口基数大,数量增长快。由材料二可知,我国超过60岁的老年人为1776亿,约占总人口的1326%,说明人口老龄化严重。

3由于老龄化高龄化严重,劳动力占人口总比重低,会导致社会赡养费用上升,政府财政压力增大;青壮年社会负担过重,劳动力不足,影响经济发展。

4面对人口老龄化,专家提出的放宽计划生育、放开二胎的政策从正反两个方面来分析,理由充分即可。赞成主要从我国人口老龄化趋势严重角度分析。不赞成主要从我国人口基数以及资源、环境压力大角度考虑。

【题目】(河南省重点中学协作体2016届高三第二次适应性考试)阅读理解。

Our “Mommy and Me” time began two years ago. My next-door neighbor and fellow mother, Christie, and I were out in our front yards, watching seven children of age 6 and under ride their bikes up and down.“I wish I could take one of my children out alone,” said Christie.

Then we worked out a plan: When Christie takes one of her children out, I’ll watch her other three. And when she watches two of mine, I’ll take someone out.

The children were extremely quick to accept the idea of “Mommy and Me” time. Christie’s daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. “She’s like a different child when there’s no one else around,”Christie shared with me quietly. With her mother all to herself, McKenzie didn’t have to make an effort to gain attention.

Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering (口吃) son, Tom, doesn’t stutter once during our activities since he doesn’t have to struggle for a chance to speak. And the other son, Sam, who’s always a follower when around other children shines as a leader during our times together.

The “Mommy and Me” time allows us to be simply alone and away with each child-talking, sharing, and laughing, which has been the biggest gain. Every child deserves (应得到) to be an only child at least once in a while.

【1】What is the text mainly about?

A. The experience of the only child being with mother.

B. The advantage of spending time with one child at a time.

C. The happy life of two families.

D. The basic needs of children.

【2】Right after McKenzie came back, the other children were ______.

A. happy B. curious

C. regretful D. friendly

【3】What is one of the changes the author finds in her children?

A. The daughter acts like a leader.

B. Sam holds her hand more often.

C. The boys become better followers.

D. Tom has less difficulty in speaking.

【4】The author seems to believe that ______.

A. having brothers and sisters is fun

B. it’s tiring to look after three children

C. every child needs parents’ full attention

D. parents should watch others’ children

【题目】根据短文内容,从短文后的七个选项中选出正确的填入空白处。选项中有两项为多余选项。

The Science of Risk-Seeking

Sometimes We decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth taking. 【1】 Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work.

The reason why any of us take any risks at all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring. 【2】 As the quality of Risk-taking was passed from on ration to the next, humans ended up with a sense of adventure and a tolerance for risk.

So why aren’t we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one Killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. 【3】

No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. 【4】 To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.

Mean taking some risks, so your brain raisers your tolerance for risk as well.

【5】 For the risk-seekers a part of the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.

As experts continue to study the science of risk-seeking, we’ll continue to hit the mountains, the waves or the shallow end of the pool.

A. It all depends on your character.

B. Those are the risks you should jump to take.

C. Being better at those things meant a greater chance of survival.

D. Thus, these well-equipped people survived because they were the fittest.

E. This is when you start to move away from your family and into the bigger world.

F. However, we are not all using the same reference standard to weigh risks and rewards.

G. New brain research suggests our brains work differently when we face a nervous situation.
