【題目】東北地區(qū)大規(guī)模開荒，造成該區(qū)域濕地面積銳減、生態(tài)環(huán)境惡化。下列對于該區(qū)域開發(fā)與保護(hù)的說法，正確的是（　�。�

A.已開墾的耕地全部退還沼澤

B.繼續(xù)開荒，擴(kuò)大水稻種植面積

C.停止開荒，建立自然保護(hù)區(qū)

D.大量使用化肥、農(nóng)藥，提高單位面積產(chǎn)量

【答案】C

【解析】

三江平原，又稱三江低地，即東北平原東北部，中國最大的沼澤分布區(qū)，在三江盆地的西南部。三江平原是指黑龍江、烏蘇里江、松花江，三條大江匯流、沖積而成了這塊低平的沃土，三江平原素以“北大荒”著稱，在1949年大規(guī)模開墾前，草甸、沼澤茫茫無際，亦有成片森林，野生動(dòng)物繁多。華人民共和國成立后，這里進(jìn)行了大規(guī)模的農(nóng)墾耕作， “北大荒”已一躍而成“北大倉”，成為我國最大的農(nóng)墾區(qū)，是小麥、大豆、玉米、水稻等重要商品糧生產(chǎn)基地。

已開墾的耕地依據(jù)實(shí)際情況退還沼澤，全部退還的說法絕對，不切實(shí)際，故A說法錯(cuò)誤；繼續(xù)開荒，擴(kuò)大水稻種植面積，大量使用化肥、農(nóng)藥，提高單位面積產(chǎn)量容易破壞生態(tài)環(huán)境，不利于保護(hù)濕地，故BD說法錯(cuò)誤；停止開荒，建立自然保護(hù)區(qū)，有利于保護(hù)濕地，保護(hù)生態(tài)環(huán)境，故C正確。故選C。

【題目】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.

【1】It is found that ________ do less housework.

A. wives B. husbands C. parents D. babies

【2】The underlined sentence “It is a different story for mothers.” probably means “________”．

A. Mothers come from different families B. Mothers like reading different stories

C. Mothers work more hours than fathers D. Different mothers have different children

A. Working outside. B. Looking after the baby.
