【答案】
【1】C
【2】A
【解析】
试题分析:
【1】由图中给出的出生人口、死亡人口和总人口数不难求出我国的出生率、死亡率和自然增长率,结合所学我国人口相关知识,可确定我国现阶段出生率、死亡率和自然增长率都较低,但由于人口基数大,每年净增的人口较多,老龄人口增加快,城市化水平还较低。综合以上分析,选项C正确。
【2】我国由于人口基数大,每年净增的人口多,再加上老龄人口增加快,是我国教育、医疗、就业压力大,A正确;我国正处于城市化的加速发展阶段,城市化发展速度快,B错;新增人口数量多,劳动力资源丰富,C错;我国人口虽然已超过最适宜人口数,但距环境人口容量这个最大人口是还有一定距离,并没有趋近与环境承载的极限,D错。

【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。
Something that makes sense is happening in Washington, D.C! Public school kids surrounded by museums and monuments are putting the ready-made learning tools to use — and actually learning.
A trip to see painter Jacob Lawrence’s Migration Series is one of almost 200 trips that Wheelock will organize this year through the nonprofit group Live It Learn It. “For many kids, school is disconnected,” says one of four full-time workers and tour leaders. “With the program, they see how what they are learning is connected to their communities.”
Seven years ago, Wheelock changed a job as a lawyer for one as a four-grade teacher. When he learned that D.C.’s public schools ranked behind those of other cities in many ways, he knew he had to do something different. He took his class to Capitol Hill for a lesson on the three branches of government — and saw his students’ interest develop quickly.
With seed money from a local couple, Wheelock developed detailed lesson plans for trips to the U.S. Holocaust Memorial Museum, the Lincoln Memorial. The group also has classes for trips to the Anacostia River, boat rides to historical forts. Word spread, and now fourth, fifth, sixth graders from the neediest public schools in the District participate.
“I’m not brave enough to take my class to a museum for over an hour!” says teacher Cathy McCoy, gesturing toward her students. “But look With Live It Learn It, what the kids learn today they’ll remember for a lifetime.”
【1】Matthew Wheelock once had an occupation as a _______.
A. teacher B. printer
C. leader D. lawyer
【2】According to the first two paragraphs, public school kids in Washington D.C. _______.
A. like to have school disconnected
B. are warmly welcomed by museums and monuments
C. are making the resources at hand available
D. are learning by going to different communities
【3】Matthew Wheelock started the new change for the reason that _______.
A. he saw his students’ interest develop quickly
B. more graders from the neediest public schools wanted to participate
C. D.C.’s public schools ranked behind in many ways
D. a local couple sponsored him a sum of seed money
【4】What will the lessons be like with Live It Learn It in Cathy McCoy’s opinion?
A. Eye-catching. B. Challenging.
C. Forgettable. D. Impressive.
