解析分析句子知leavingthebag...是分词短语作状语；而thebag和lie间是主谓关系，故用lying的形式；而disappear和rushout是句子的谓语动词；因此B正确。BⅣ.单项填空B2.Therearebothadvantagesanddisadvantagesintheschemeproposed,but

Ithinkweshouldbenefitbyadoptingit.A.onbalance B.outofbalanceC.onthebalance D.offbalance

解析考查分数表达和主谓一致。当分数中分子大于1时，分母需用复数，故排除A、B两项；

“分数/百分数+of+名词”作主语时，谓语动词的单复数取决于名词，本句中people为复数，故选C。CofthepeopleontheNe8.The
