(A)
I teach at UNLV three times per week. Last Monday, at the beginning of class, a young man asked me why I always seemed to be so cheerful.
His question reminded me of something I’d read somewhere before. “Every morning when you get up, you have a choice about how you want to live your life that day.” I said. “I choose to be cheerful.”
“Let me give you an example,” I continued. “Besides teaching here, I also teach out at another college in Henderson, 17 miles down the highway from where I live. One day a few weeks ago, I drove those 17 miles to Henderson. I drove off the highway and turned on to College Drive. I only had to drive another quarter mile down the road to the college. But just then my car died. I tried to start it again, but it didn’t work. So I put my car lights on, took my books, and walked down the road to the college.”
“As soon as I got there, I called AAA and arranged (安排) for a tow truck (牵引车) to meet me at my car after class. A teacher in the office asked me what has happened. ‘This is my lucky day,’ I replied, smiling.”
“Your car breaks down and today is your lucky day ” She was puzzled (疑惑的). “What do you mean ”
“I live 17 miles from here.” I replied. “My car could have broken down anywhere along the highway. It didn’t. Instead, it broke down at the perfect place: off the freeway, within walking distance of here. I’m still able to teach my class, and I’ve been able to arrange for the tow truck to meet me after class. If my car was meant to break down today, it couldn’t have been arranged in a more convenient fashion.”

9. 海鲜中含As(V),水果中的维C可将As(V)转化为毒性更强的As(Ⅲ)。已知:
(1)某海鲜中含As(V)含量为,某水果中的维C含量为。人体内As(V)转化为As(Ⅲ)的转化率为30%,人体允许的As(Ⅲ)(以计)的最大摄入量约为60mg,若不慎中毒,至少需同时摄入多少质量的海鲜和水果?并根据计算结果,判断两者一起食用会引起砷中毒的“谣言”真假?[M(As)=75、]_______。
向含的废水加入形成沉淀,可去除废液中的砷元素。实验表明,溶液pH保持在4.5左右时,砷的去除果最高,沉淀中往往同时含有和。已知25℃时,、、、。下图是含As(V)的微粒在水溶液中的物质的量分数随溶液pH的变化。
(2)实验发现,向pH为4.5的废水中加入比As总含量略多的,在有效沉淀As元素的同时,还能加快沉淀沉降,原因可能是_______。若加入过量太多,虽能加快沉淀沉降,但会导致溶液中As元素残留最过高,原因可能是_______。
(3)pH大于11.5后,在含砷微粒中的物质的量分数最高,为什么在pH大于11.5的情况下除砷,砷的去除效果反而下降_______。
(4)加入除砷并保持pH=4.5不变,充分沉淀后,溶液中残留的含量最高的含砷微粒是_______,其剩余浓度为_______。
