【题目】东北地区大规模开荒,造成该区域湿地面积锐减、生态环境恶化。下列对于该区域开发与保护的说法,正确的是(  )

A.已开垦的耕地全部退还沼泽

B.继续开荒,扩大水稻种植面积

C.停止开荒,建立自然保护区

D.大量使用化肥、农药,提高单位面积产量

【答案】C

【解析】

三江平原,又称三江低地,即东北平原东北部,中国最大的沼泽分布区,在三江盆地的西南部。三江平原是指黑龙江、乌苏里江、松花江,三条大江汇流、冲积而成了这块低平的沃土,三江平原素以“北大荒”著称,在1949年大规模开垦前,草甸、沼泽茫茫无际,亦有成片森林,野生动物繁多。华人民共和国成立后,这里进行了大规模的农垦耕作, “北大荒”已一跃而成“北大仓”,成为我国最大的农垦区,是小麦、大豆、玉米、水稻等重要商品粮生产基地。

已开垦的耕地依据实际情况退还沼泽,全部退还的说法绝对,不切实际,故A说法错误;继续开荒,扩大水稻种植面积,大量使用化肥、农药,提高单位面积产量容易破坏生态环境,不利于保护湿地,故BD说法错误;停止开荒,建立自然保护区,有利于保护湿地,保护生态环境,故C正确。故选C。

【题目】Research says that husbands do not do their fair share of work around the house.A study from an American university says that men seldom do the same share of housework.Researchers interviewed 182 working couples who became first-time parents.Both husbands and wives worked almost the same number of hours in full-time jobs.However,men did five hours a week less housework than women after their baby was born..

It is a different story for mothers.Becoming a parent added about 21 hours a week to a mother's work.Most of this was looking after her baby.New fathers did not do more work because they did not realize the mother was doing so much more.Another reason is that after a baby is born,fathers follow the “traditional” roles.That is,the mother looks after the baby and the father works outside.This happens even when the mother is working the same number of hours in her job.
