A blind boy sat on the steps of a building with a hat by his feet. He held up a sign which said: “I am blind, please help.” There were only a few coins in the hat. A man was walking by. He took a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words. He put the sign back so that everyone who walked by would see the new words. Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy recognized his footsteps(脚步) and asked: “Were you the one who changed my sign this morning? What did you write?” The man said: “I only wrote the truth. I said what you said but in a different way.” What he had written was: “Today is a beautiful day but I cannot see it.”

Do you think the first sign and the second sign were saying the same thing? Of course both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the day, but the boy could not enjoy it because he was blind. The first sign simply said the boy was blind. The second sign reminded people they were lucky that they were not blind.

There are at least two lessons we can learn from this simple story. The first is: Be thankful for what you have. Someone else has less. Help where you can. The second is: Be creative. Think differently. There is always a better way!

由细颗粒物造成的灰霾天气对人体健康的危害甚至要比沙尘暴更大。粒径10微米以上的颗粒物,会被挡在人的鼻子外面;粒径在2.5微米至10微米之间的颗粒物,能够进入上呼吸道,但部分可通过痰液等排出体外,另外也会被鼻腔内部的绒毛阻挡,对人体健康危害相对较小;而粒径在2.5微米以下的细颗粒物吸入人体后会直接进入支气管,干扰肺部的气体交换,引发包括哮喘、支气管炎和心血管病等方面的疾病。这些颗粒还会进入血液,其中的有害气体、重金属等溶解在血液中,对健康的伤害更大。

这段文字意在说明()。

A.不同粒径的颗粒物对人体健康的不同影响

B.灾害天气中各种尺寸颗粒物的致病机理

C.重金属等会溶解于血液中危及人体健康

D.灰霾天气中的细颗粒物对人体健康伤害大
