A.betteruseofgreenspacefacilitiesshouldbemadesoasto　improvethe qualityofourlife.

B.attentionmustbedirectedtotheimprovementofrecreative possibilities.

C.theurbanenvironmentisprovidingmorerecreationactivitiesthanit didmanyyearsago.

D.prioritymustbegiventothedevelopmentofobligatory　activities.

(分析：B、D两项中均有mustbe，语气太绝对化，故一般被排除。考生结合短文内容在剩下两项中进行选择，命中率就极高了。)

(二)选项中含有不十分肯定的语气词一般是正确答案项。

这些语气词有：can，could，may，should，usually，might，most(大多数)，moreorless， relatively，belikelyto，possible，whetheror，notnecessarily等。

B.inmanycountriessuccessoftendependsonone‘ssocialstatus

C.Americanbusinessesaremoredemocraticthanthoseinother countries

D.businessesinothercountriesarenotascompetitiveasthosein America

(分析：选项B中often一词，语气委婉，不十分肯定，故为答案。而其它三项中所表达出的语气都明显绝对化。)
