阅读下文，完成1-4题。

　　①历史上有许多科学家坚持不懈，探求真理，潜心钻研，造福人类。他们的成就辉煌灿烂，他们的品格更是光彩照人。

　　②居里夫人，当有人要以重金购买镭的专利时，她不仅断然拒绝，而且毫不保留地将镭的“秘密”公之于世。她不谋私利，甘愿为社会做贡献的高尚人格堪称楷模。

　　③布鲁诺为传播哥白尼的“日心说”而被烧死在罗马鲜花广场。他在火焰和浓烟的包围中，仍然坚信：“火并不能把我征服，未来的世界会了解我，知道我的价值。”他支持真理、不畏邪恶，推进了人类文明和科学的进程。

　　④我国著名科学家钱学森，在美国人重金留聘面前，毅然选择了归国之路。他名扬海外、身在他乡，但心星想念的是祖国人民，渴望的是祖国繁荣昌盛。他的赤子之心、民族永远感召着亿万中国人。

　　⑤科学家高士其，原名高仕镆。当有人问他为什么改名时，他说：“去掉‘人’旁不官，去掉‘金’旁不为钱。”改名实为小事，但足以表明科学家那崇高的理想和人生目的。

　　⑥与此相反，有的人虽也为科学殿堂添砖加瓦，但品格低下。创立热传导数学理论的立叶，在严酷的权力斗争中，时而效忠拿破仑，时而效忠路易十八，拿破仑东山再起，他又一次宣誓拜倒在其脚下。当人们再提到热传导数学理论时，还有谁对这位政治上的两面派肯于称道呢？

　　⑦至于那些在科学研究中弄虚作假、剽窃抄袭、诋毁他人、抬高自己的做法，_________________________________________________。

　　⑧爱因斯坦曾经说过：“第一流人物对于时代和历史进程的意义在其道德品质方面也许比单纯的才智成就方面还要大……”就科学家而言，这句话_____是对其科学建树重要作用的充分肯定，_____是对其人格价值的突出强调。可见，具备良好的品格对科学家是何等重要啊！这也就是所谓学科学，首先要学做人的道理所在。让我们铭记：一个有高尚人格的科学家，才是真正伟大的科学家。

Last winter, when I was heavily pregnant, I was visiting my sister and brother-in-law's house and had to park in a nearby parking lot because they didn't have accessible parking. The snow was extremely heavy and there was lots of ice on the ground --- not many people had ventured out that evening!

When I returned to my car around 11pm, I noticed that I was the only car left. Nervously, I hopped into the car and let it warm up a bit. When I finally tried to drive away, my wheels began to spin. I was stuck! I spun and spun and wondered what to do.

All of a sudden, in my rear view mirror, I saw four teen-aged boys approaching my car. They were walking side by side in a line and dressed a bit like gang members --- at least I thought that's what they looked like. My car was in a very isolated area and I began to panic. I was certain they were coming to my car to harm me. Terrified, I just froze. One of the young men tapped on my window and said "Excuse me, Ma'am, can we help you? You seem stuck." Still afraid and fearing the worst, I said "I am stuck." And the young man said "It's okay, stay in your car and we'll push you out of the snow." And they did!

When they finally got me out of the snow, they smiled and waved. I rolled down my window and thanked them, embarrassed to have judged them so poorly.
