呃……,这有点复杂,我们这么想吧:陆地比热较小,不容易保热,早上温度再怎么高,晚上的\'温度也很快就降下来了。再来,热空气密度较大,比较轻,会上升;冷空气密度较小,比较重,会下降,这道理大家懂吧?综合以上,晚上的时候,陆地温度较低,空气就会下降,下降的同时呢又把一整天散布在空气中的灰尘啊、油烟啊、废气啊……,之类所有想得到的污染物全都带到地球表层。
那你们知道吗,其实清晨的空气不但脏,它还是最脏的!为什么呢?因为啊!前面提到的那些跟着冷空气下来的“偷渡客”会慢慢的、慢慢的堆积,直到太阳升起,唉等等等等等!并不是太阳升起就好,还要等到温度稍微升高,污染物沉淀的速度小于污染物以扩散作用在均匀散开的速度时,空气品质才会渐渐好转……,但是!早晨的温度还很低啊!有些时候甚至太阳都还没升起,那个时候正是污染物沉积量的巅峰,这时的空气新鲜得像结肠里那块水和细菌、矿物质合成的黄金。
其实灰尘多的空气吸多了,就是产生咳嗽之类的小病症,那如果说有“天天晨跑”的这种“好习惯”,大概就肺炎。假设各位晨跑的地点附近有大都市或重工厂,我只能说各位太会挑地点了!兄弟!过来!有没有看见肺癌在前面等着各位?
对于能每天坚持慢跑的人,我望尘莫及,有恒心、有毅力!但良心建议——除了清晨之外,爱跑多久,随便!

29、D(2分)
在许多不该沉默的场合,人们往往用“沉默是金”来解释自己的行为。我很是不理解,沉默的价值真的是金吗?
试想,如果沉默是金,为何人们会崇尚“毛遂自荐”?为何人们会赞扬闻一多“拍案而起”?如果沉默是金,为何商家要不惜千金做广告?为何选举时要用演讲来拉选票?如果沉默是金,为何法庭沉默结果多为败诉,为何谈判中沉默往往意味着僵局?如果沉默是金,那么金又在何处得到体现呢?
报载:X年X月X日上午,一少年不慎落水,其伙伴向围观者求救。围观者无人肯应,硬是看着少年永远地沉在“水中”。花儿一样的生命在沉默中含恨而去,这样的沉默又有何价值?弃之犹恐不及,如何能与金子媲美?显然,沉默不是“真金”,那么沉默者为何沉默?
“沉默其实是一种解脱”,郑智化的歌道出沉默者的内心世界。沉默者用“沉默是金”来装饰自己,逃避责任,沉默正如“镀金”,给沉默者的自私、软弱,镀上一层虚伪的光环。
当然,并不是所有的沉默都是为了逃避责任,有些人在遭遇不公平的事时,比如在不良青年的无理要求之后,保持沉默,他们自以为这是恬静隐忍的.美德。殊不知,正是他们的沉默,使那些盛气凌人的人更嚣张,使更多的人受到伤害。这种“美德”,不要也罢。
不过,请别误会,不是说沉默一无是处。有时候沉默,如听音乐时,确能收到无声胜有声的效果。只是说,在不该沉默的时候,就不能沉默。
“沉默啊沉默,不在沉默中爆发,就在沉默中死亡。”鲁迅也是这样说的。沉默者,爆发吧!
19、(4分)①一些人仅仅为找好工作或者通过读博推迟就业而读博。(1分)②一些人为职称晋升或者为了获得进入高校或科研单位而读博,读博已经成为“敲门砖”。(2分)③人们都是为了某种功利目的去读博,而不是真真的为了知识和学术去读博。(1分)(意思对即可给分。)
20、(5分)①功利化目的使博士生教育俨然成了“职业教育”,当下博士生数量急剧膨胀。(1分)
②博士论文抄袭现象等学术不端行为,加剧了人们对博士质量的担忧。(2分)
③我国博士生导师数量远远不能满足日益增长的博士生数量的要求,博士生导师所带学生过多。(2分)
21、(6分)这是一个开放性的探究题,答案可以从两个方面去组织。
①赞同。一、博士教育回归精英教育的核心是提高博士质量,也是进一步拓宽博士就业渠道和机会的需要。二、博士教育精英化可以有效地解决目前的关键问题,如读博的功利性色彩可以得到控制,挤掉博士培养中的泡沫和水分,有效地制止学术不端行为的发生等。
②不赞同。一、我国国情和美国不一样,我们的人口基数大,博士生的比例相同的话,我们在人数上自然要超过美国,不是所有的事情都向美国看齐,以他为标杆。二是我们国家急切需要大量的博士人才,时不我待,只要注意质量监控,宽进严出,保证质量的同时也可以讲求数量。(言之成理即可酌情给分。)
