题目内容
【题目】2016年4月丹麦奥胡斯大学用我国大科学工程郭守敬望远镜数据取得了一项重大研究成果：太阳有一天可能会用比往常强烈数千倍万倍的超级耀斑“轰炸”地球，导致大气层沸腾，甚至让生命灭绝。结合所学知识，完成下列各题。
【1】关于材料中提到的“超级耀斑”，说法正确的是( )
A. 出现在太阳色球层 B. 每11年必爆发一次
C. 温度比其他区域低 D. 肉眼可以直接观测
【2】“超级耀斑”导致大气层沸腾，甚至让生命灭绝的主要原因是( )
A. 使地球产生“磁暴”现象 B. 会影响地球无线电通讯
C. 带来大量能量，使得地球大气异常升温 D. 会产生极光现象
【答案】
【1】A
【2】C
【解析】
【1】耀斑出现在太阳的色球层，是突然出现的大而亮的斑块，温度比其他区域高，不可使用肉眼直接观测；太阳活动的周期约为11年，而不是每11年都必须爆发。故选A。
【2】从材料中“大气层沸腾”可以判断“超级耀斑”会带来大量能量，使地球大气异常升温；“磁暴”、影响无线电通讯和极光都不至于让生命灭绝。故选C。

This 10 reminded me of one of my favorite quotes, ＂When I was a young man, I wanted to change the world. I found it was 11 to change the world, so I tried to change my nation.

Now, as an old man, I 15 the only thing I can change is myself, and 16 I realize that if long ago I had changed myself, I could have made an impact(影响) on my family and 17 on our town. The impact could have changed the nation and I could indeed have changed the 18 .＂
For those of us who want to make a(n) 19 in the world, it’s important we remember what Bucky Fuller said, ＂Think globally, but act 20 .＂ For me, I’m going to make it point to meet more of my neighbors-staring now.
