讨论下,两道模考中遇到的语法题,confusing,比我想象中语法要难啊~

1.The population of India has been steadily increasing for decades, and it  will probably have what is estimated as 1.6 billion people by 2050 and surpass China as the world's most populous nation.

A.

b.they are likely to have

c.the country will probably have

d.there will probably be

e.there will be an estimated

答案C,我选D,因为白勇语法上曾说过表示事实一类存在的最好用THERE BE句型,STH HAVE什么不是太好.听听大家意见~~~~~

2.Industrialization and modern methods of insect control have improved the standard of living around the globe while at the same time they have introduce some 100,000 dangerous chemical polltants, having gone virtually unregulated since they were developed more than 50 years ago.

a.

b.while at the same time introducing some 100.000 dangerous chemical pollutants that have

c.while they have introduced some100.000 dangerous chemical pollutants at the same time,and have

d.but introducing some 100.000 danerous chemical pollutants at the same time that have

e.but at the same time introduce some 100.000 dangerous chemical pollutants,having

选B.觉得奇怪,WHILE后面还是应该跟句子啊?如果是省略了主语,谓语形式也不应该是introduing啊.请赐教~~~~~~~~

1,人口的事情,还是对未来的估计可不是什么自然状况或者是事实.其次,确实如2楼的兄弟所说,动词也不对应.

2.while doing.其次,如果使用having的话,动作的发出者就是Industrialization and modern methods .

 surpass China as the world's most populous nation.

只有country才能和china对应,并且成为most populous nation
