【正文】 ndustrialization but also pollution. From the 1930s the creek could no longer be used as a source for tap water, and no living fish or shrimp could be found. Suzhou Creek in my memory is dark and smelly. I used to go to the riverbank to watch the sewage disposal running out from the chemical plants when I was a little girl. We didn’t know it was pollution. We thought it was a red waterfall, says Huang Qi, a 57yearold Shanghai resident. So the residential houses along the creek were unpopular, and only migrants with low ines would live in that area, she says. However, things have changed. The plants were closed and turned into riverside parks and the apartments in the new highrises, especially those facing the creek, are much sought after. East China University of Political Science and Law This is the famous former Saint John’s University, China’s firstever modern institution of higher education established by missionaries from the United States in 1879. The buildings bine Chinese and Western elements. Address: 1575 Wanhangdu Road, Changning district The old residential area After you leave the university from its east gate you will enter a shabby neighborhood that retains its original look. The alleys are narrow and the houses are overcrowded. Some things have not changed for many generations, such as raising chickens at home. Address: West Guangfu Road Moganshan Road This is an artsy street that has bee very popular among artists and fashionistas in recent years. Graffiti covers the walls on the winding street, where you can find a cluster of art galleries and creative industry offices. Sihang Warehouse Four banks jointly funded the construction of this warehouse, so it is named sihang, or four banks.

The building, which is also a masterpiece left by the Hungarian architect Laszlo Hudec in the 1930s, has been recently transformed into a center of creative industry workshops. Address: 1 Guangfu Road, Zhabei district 。背斜構(gòu)造往往是儲(chǔ)藏石油的“倉庫”。由于上面地層的壓力，分散的油滴被擠到四周多孔隙的巖層中，就成為儲(chǔ)油地層。地球主要正是通過這個(gè)窗區(qū)把從太陽獲得的熱量中的 70％又以長波輻射形式返還宇宙空間，從而維持地面溫度不變，溫室效應(yīng)主要是因?yàn)槿?類活動(dòng)增加了溫室氣體的數(shù)量和品種，使這個(gè) 70％的數(shù)值下降，留下的余熱使地球變暖的。 地球大氣中起溫室作用的氣體稱為溫室氣體，主要有二氧化碳、甲烷、臭氧、一氧化二氮、氟里昂以及水汽等。 大氣對(duì)太陽短波輻射幾乎是透明的，卻強(qiáng)烈吸收地面長波輻射，它自己也向外輻射更長的長波輻射，大氣對(duì)地面起到了保溫作用。地面在接受太陽短波輻射而增溫的同時(shí)，也時(shí)時(shí)刻刻向外輻射電磁波而冷 卻。物體溫度越高，輻射的波長越短。 A、 40 B、 50 C、 60 D、 70 水汽在大氣中含量很少，但變化很大，其變化范圍在 C ％之間，水汽絕大部分集中在低層。以上，到 1000公里上下，就變得以 A 為主了。 A、三葉蟲 B、鸚鵡螺 C、筆石 D、恐龍 1屬于石炭紀(jì)時(shí)期的煤炭儲(chǔ)量約占全世界總儲(chǔ)量的 B %以上。 A、城市生活污染和工業(yè)廢水大量排放入海 B、魚類大量繁殖 C、廢油排入海洋 D、酸雨 1硬度 A 以上幾乎都應(yīng)屬于寶石之類的礦物。 A、 10 B、 20 C、 30 D、 40 1紅樹林是一種稀有的 B 植物。 城市年降水量比郊區(qū)多 510％。 A、海成湖 B、火口湖 C、冰川湖 D、河成湖 森林地區(qū)要比無林地區(qū)，降水量大，一般要大 B ％。 A、沉積巖、花崗巖和變質(zhì)巖 B、沉積巖、巖漿巖和變質(zhì)巖 C、花崗巖、玄武巖和變質(zhì)巖 D、花崗巖、玄武巖和沉積巖 電離層大致在中間層位置，但準(zhǔn)確位于高于海面 C km A、 50~500 B、 60~800 C、 60~1000 D、 100~1000 B 是世界 上含沙量最大的河。 A、幾千 B、幾萬或幾十萬 C、幾百萬或幾千萬 D、幾億 寒武紀(jì)、奧陶紀(jì)、志留紀(jì)、泥盆紀(jì)、石炭紀(jì)和二疊紀(jì)屬于 B A、元古代 B、古生代 C、中生代 D、新生代 三疊紀(jì)、侏羅紀(jì)和白堊紀(jì)屬于 C A、元古代 B、古生代 C、中生代 D、新生代 非常丑陋的 A ，在中國卻有一個(gè)非常迷人的名字 美人魚 ，學(xué)名叫作儒艮。 1 1992年世界環(huán)境與發(fā)展大會(huì)上通過的沙漠化定義是“包括氣候和人類活動(dòng)在內(nèi)種種因素造成的干旱、半干旱和亞濕潤地區(qū)的 土地退化 ”。 1工業(yè)化大量燃燒煤和石油，向地球大氣排放巨量的廢氣。 1氮?dú)庹即髿赓|(zhì)量的 76 ％，它的性質(zhì)很穩(wěn)定，只有極少量的氮能被 微生物 固定在土壤和海洋里變成有機(jī)化合物。晶族內(nèi)又分為 七 個(gè)晶系。礦物晶體中可能的對(duì)稱型共有 32 種。揮發(fā)份中水蒸汽約占總量的 81 %， CO2占 10 ％，還有 SO C
