【題目】我國(guó)把“實(shí)行計(jì)劃生育”作為長(zhǎng)期基本國(guó)策,主要原因是( 。
A. 人口地區(qū)分布不均 B. 人口增長(zhǎng)與社會(huì)、經(jīng)濟(jì)、資源、環(huán)境的矛盾突出
C. 農(nóng)村人口比重大 D. 城鎮(zhèn)人口數(shù)量不斷增多
【答案】B
【解析】
自20世紀(jì)70年代初期我國(guó)大力推行計(jì)劃生育政策以來(lái),全國(guó)大約少生了約4億人,人口過(guò)快增長(zhǎng)的勢(shì)頭得到有效遏制。特別是近十年來(lái),人口的出生率和自然增長(zhǎng)率明顯下降。但是,由于我國(guó)人口基數(shù)大,青少年的比重高,在今后一段較長(zhǎng)的時(shí)期內(nèi),人口總量還將持續(xù)增長(zhǎng)。在度過(guò)高峰期后,人口總數(shù)才會(huì)呈下降趨勢(shì),但人口素質(zhì)不高的狀況在短期內(nèi)還難以根本改變,人口與經(jīng)濟(jì)、社會(huì)、資源、環(huán)境的矛盾依然會(huì)十分突出。因此,實(shí)行計(jì)劃生育,控制人口的數(shù)量,提高人口的質(zhì)量,是我國(guó)一項(xiàng)長(zhǎng)期的基本國(guó)策,故選B。

It was Saturday yesterday. I had no lessons. I got up at six. After breakfast, I went to Taihu Farm by truck (卡車) with my classmates to help the farmers with apple harvest (收獲). As soon as we got there, we began to pick apples. But some of the apples were too high for me to reach. Jim is very strong and he lifted a ladder (梯子) and held it for me. So I was able to pick them. Some of us took the baskets of apples to the truck and some put the baskets of apples onto the truck.
It was hard work, but we all felt very happy.
