A.人类盲目的开发森林和草原

B.北方地区降水量低,常年干旱

C.环境污染导致植被大量死亡

D.野生动物的种类和数量锐减

答案

答案:A

题目分析:沙尘暴发生不仅是特定自然环境条件下的产物,而且与人类活动有对应关系,人为过度放牧、滥伐森林植被,盲目地开发森林和草原,尤其是人为过度垦荒破坏地面植被,扰动地面结构,形成大面积沙漠化土地,直接加速了沙尘暴的形成和发育,因此扩大畜牧业发展会对草原植被造成破坏,增加了土地沙漠化的进程,不利用防治沙尘暴的发生,因此沙尘暴形成的人为因素主要表现在人类盲目地开发森林和草原,选A。

There’s a guy like me in every state and federal prison in America,I guess—I’m the guy who can get these for you:cigarettes,a bag of cigar,if you want that,a bottle of wine to celebrate your son or daughter’s high school graduation,or almost anything else...within reason,that is.It wasn’t always that way.

I came to Shawshank when I was just twenty,and I am one of the few people in the prison who is willing to admit what he did.I committed murder.I put a large insurance policy on my wife,who was three years older than 1 was,and then I fixed the brakes of the car her father had given us as a wedding present.It worked out exactly as I had planned,except I hadn’t planned on her stopping to pick up the neighbour woman and the woman’s son on the way down Castle Hill and into town.The brakes let go and the car crashed through the bushes,gathering speed.Bystanders said it must have been doing fifty or better when it hit the base of the Civil War statue in the town arid burst into flames.

I also hadn’t planned on getting caught,but caught 1 was.I got a pass into this place.My state has no death penalty(死刑),but I was tried for all three deaths and given three life sentences,to run one after the other.That fixed up any chance of parole(假释)I might have,for a long,long time.The judge called what I had done‘an extremely evil crime’, and it was ,but it is also in the past now.

Have I transformed myself,you ask ?I don’t know what that word means,at least as far as prisons and corrections go.I think it’s a politician’s word.It may have some other meaning,and it may be that 1 will have a chance to find out,but that is the future...

I was young,good—looking,and from the poor side of town.I met a pretty,headstrong girl who lived in one of the fine old houses on Carbine Street.She got pregnant later.Her father was agreeable to the marriage if 1 would take a job in the company he owned and ‘work my way up’.I found out that what he really had in mind was keeping me in his house and under his thumb,like a disagreeable pet that has not quite been housebroken and which may bite.Enough hate eventually piled up to cause me to do what I did.

Given a second chance 1 would not do it again,but I'm not sure that means I am transformed.
