【题目】阅读材料,完成问题。

材料 上世纪80年代以来,新疆开始大范围推广使用地膜覆盖技术,截至2014年,新疆农作物覆膜面积已达4700万亩左右,占农作物总播面积的70%以上,年使用地膜总量达18.5万吨。与此同时,由于新疆使用的地膜厚度薄、易破损,人工捡拾劳动强度大、再加工利用较难,导致人们对农田废旧地膜回收和再利用的积极性不高,全区农田废旧地膜回收利用率还不到10%。废旧地膜在农田土壤中逐年增多,污染持续加剧,目前新疆已成为我国乃至世界上“白色污染”最严重的区域之一。

分析新疆成为我国“白色污染”最严重区域的原因。

【答案】地膜不易分解;使用时间长,地膜残留积累量大;使用面积广;使用量大;厚度薄,回收和再加工困难;当地农民回收和再利用意识不强,积极性低;

【解析】

试题分析:仔细阅读材料,结合材料中关键信息分析原因;由材料可知“上世纪80年代以来,新疆农作物覆膜面积已达4700万亩左右,占农作物总播面积的70%以上,年使用地膜总量达18.5万吨”,说明新疆地膜使用量大且面积广;由“地膜厚度薄、易破损,人工捡拾劳动强度大”可知回收加工困难,由于使用时间较长,在地里残留量大,难以收集;“人们对农田废旧地膜回收和再利用的积极性不高”可知当地农民环保意识薄弱。

【云南省玉溪市一中学2016届高三下学期第一次月考】A good laugh is like a mild workout. It exercises the muscles, gets the blood flowing, decreases blood pressure and improves sleep patterns and the immune system. 【1】.

Don’t take life too seriously. We all have obstacles in life and we all make mistakes. 【2】 In fact, if you can laugh light-heartedly at your own fault, you’ll find that you give yourself that extra happiness and confidence increase that can get you over any obstacle.

Find the humor in a bad situation. Sure , there are some situations where you are really sad. 【3】 The next time you feel the stress levels rising, take a minute to think about the funny side of the situation and laugh over the things you cannot control. This will lower your blood pressure, blood sugar levels and heart rate.

Remind yourself of funny moments from the past. Perhaps a friend told you a great joke the other day or your children or pets did something amusing. 【4】 Sometimes just reliving a funny moment can cause the endorphins(内啡肽), natural painkillers, to kick in.

【5】 As the saying goes, laughter is contagious(会传染的). So make a point of seeking out positive people who aren’t afraid to laugh at themselves and are good at finding humor in life’s situations. Young children are especially skilled at finding laughter and joy in everyday moments.
