lanzhouis situated in the temperate zone and enjoys a semi-arid climate (kppen bsk) with hot summers and very cold and dry winters. mean annual rainfall is 315 millimetres (12.4 in), almost all of which falls from may to october. the winters are so dry that snow is extremely rare.

in regard to air pollution lanzhou has some of the worst air quality of all cities in china. according to the blacksmith institute, lanzhou is one of the 30 most polluted cities in the world, with its tsp (total suspended particle) rating 247% above that of the gansu state recommendation. the air quality is so poor that at times one can not see lanshan, the mountain rising straight up along the south side of the city. at one point, a controversial suggestion was put forward to bulldoze a mountain adjacent to the city, in order to let fresh air in to the bowl where lanzhou is situated. it was suggested on the premise that the surrounding mountains block a free flow of air in the city. the city is located in a narrow river valley with an unfortunate curve causing it to be hemmed in with no free air flow. lanzhou is also the home of many factories, including some involved in petroleum processing, and suffers from large dust storms kicked up from the gobi desert, especially in the winter and spring.

from where i stand ， i am not in favor of encouraging kids with cash just because they have got good marks 。

my parents used to encourage me like this。 whenever i made progress in studies ， they bought me my favorite books ，which not only motivated me to learn ，but also helped me get along well with my studies。

to get kids motivated to learn ， i think we should not treat every child in the same way。 to some students ， oral praise is essential 。 don’t save the praise for only the top score。 if possible， involved other adults in praising them 。 however， this method may not work well with other kids。 maybe what is more important to them is to water a movie or go on a trip together with their parents 。 it just depends。

dear mr. seaton，

thank you very much for taking me with you on that splendid outing to london. it was the first time that i had seen the tower or any of the other famous sights. if i'd gone alone, i couldn't have seen nearly as much, because i wouldn't have known my way about.

the weather was splendid on that day, which i thought was rare. i still remember some people told me that in britain there was weather and no climate. during the same day, it might snow in the morning, rain at noon, shine in the afternoon and be windy before the night falls. so i think i was lucky.

i think the river trip was the best thing of all. london really came alive for me as we saw it from the thames during that wonderful journey down to greenwich. it was all tremendously exciting - a day that i shall never forget.

thank you for giving me such a great birthday treat.

yours sincerely,

linda chen

亲爱的seaton先生,

非常感谢你带我到伦敦与你灿烂的郊游。这是我第一次看到了塔或者其他的著名景点。如果我独自走了,我不能看到那么多,因为我不知道我的方式。

那天天气很灿烂,我认为是罕见的。我还记得一些人告诉我,在英国天气和气候。在同一天,可能早上雪,雨在中午、下午发光,风在夜幕降临之前。所以我认为我很幸运。

我想这条河旅行是最好的。伦敦真的活着对我来说我们看到来自泰晤士河在这美妙的旅程到格林威治。这都是非常令人兴奋的一天,我永远不会忘记。

谢谢你给我这样一个伟大的生日请客。

你的真诚,

陈琳达
