Our schl desn't allw smking.
易错点提醒：prmise sb. t d答应(某人)做某事注意：allw sb. t d sth.和permit sb. t d sth.意思大致相同，都是不定式作宾语补足语结构；而prmise (sb.) t d sth.是不定式作主语补足语，故prmise后的“sb.”如果省略，基本不影响句意。

Peple in Amsterdam have been enjying the benefits f cycling fr years. The idea began abut 50 years ag, and was first knwn as① “white bikes”. Amsterdam is a gd city fr cycling because it's flat and therefre② cnvenient③ fr bikes. There are als plenty f④ places fr bicycle parking⑤ and mst streets in the city centre have a bicycle path⑥. Because f⑦ its cnvenience fr bicycles, Amsterdam has becme very ppular with⑧ cyclists—an amazing 38% f all trips are made by bike. Sme peple even call Amsterdam “the City f Bicycles”. 【1】【1】call Amsterdam “the City f Bicycles”是“call＋宾语＋宾补”结构，宾补由名词短语充当。
Where did the idea f “white bikes” cme frm⑨？ In the 1960s, a grup f cycling fans came up with⑩ an idea. They believed that it wuld be better fr everybdy if cars weren't allwed in the city centre and nly bicycles were. 【2】 They were hpeful that this wuld help t save energy, reduce pllutin and prvide free public transprt.

Peple wuld leave the bike in the place where they finished their jurney, s that smene else culd then take it and use it frm there. 【4】 Sn after, hwever, prblems came up and the “white bikes” all disappeared⑫—thieves stle them all in a matter f⑬ weeks!
【2】that引导宾语从句，在that引导的宾语从句中又包含if引导的条件状语从句。【3】painted hundreds f bicycles white是“paint＋宾语＋宾补(形容词)”结构。【4】leave the bike in the place是“leave＋宾语＋宾补(介词短语)”结构。where引导定语从句，修饰先行词the place，s that引导目的状语从句。
In 1999, the “white bikes” returned t Amsterdam—this time with a cmputer tracking⑭ system t recrd their every mve! T take a bicycle, yu had t put in a special card. The new “white bikes” were nt actually⑮ white but painted in bright clurs. The bikes were parked at special parking places. Thus peple wh wanted t use them had t take them t anther special parking place near their destinatin⑯ and leave them there.Thanks t⑰ the ideas and effrts f many peple, like the cycling fans f the 1960s and thse wh enabled⑱ the return f “white bikes”， yu can nw enjy clean air and easy transprt in central Amsterdam. 【5】【5】短语thanks t...作状语，wh引导定语从句，修饰先行词thse, wh在从句中作主语。

多年来阿姆斯特丹的居民一直享受着骑自行车的益处。这源于大约50年前，最初被称为“白色自行车”的想法。阿姆斯特丹是个适合骑行的城市，它地势平坦，因此(therefre)方便骑行。也有很多地方可以停放(parking)自行车，市中心的大多数街道都有自行车道(path)。由于为骑行提供便利，阿姆斯特丹非常受骑行者的欢迎——有高达38%的出行使用自行车。有些人甚至称阿姆斯特丹为“自行车之城”。“白色自行车”的概念来自哪里呢？20世纪60年代，一群骑行爱好者提出(cme up with)了一个想法。他们认为，如果市中心不允许使用汽车而只能用自行车，这会让所有人都受益。他们希望这样能够节约能源，减少污染，并提供免费的公共交通。这群人将数百辆自行车涂成白色，放置在阿姆斯特丹的许多地方供人们使用。任何人都能够骑这些自行车做短途出行。人们在行程结束时就地停放自行车，以便其他人能继续使用。然而不久就出了问题，“白色自行车”全都消失( disappear)了，小偷在几周内偷光了所有的车！
1999年，“白色自行车”回到了阿姆斯特丹，这次车安装了电子跟踪(tracking)系统以记录它们的“一举一动”！要使用自行车，必须插入专用的卡片。新的“白色自行车”实际上不是白色的，而是被涂上了鲜艳的颜色。自行车要停放在专用的停车场。因此，使用者到达目的地(destinatin)之后，必须将自行车停放到附近的专用停车场。由于这个创意以及众多人的努力，如20世纪60年代的骑行爱好者和那些让“白色自行车”回归的人，现在人们可以在阿姆斯特丹的市中心享受清新的空气和便利的交通。
如今，“白色自行车”的概念已经在世界范围内广泛传播，全球的共享单车也在增加。在中国，越来越多的城市拥有了自己的“白色自行车”计划。本地人和游客都喜欢骑共享单车，因为共享单车方便又便宜，可以节省能源、减少空气和噪声污染，使人享受在城市里运动的益处。然而，问题也随之而来，例如自行车被盗和停放问题。幸运的是，人们正在尝试不同的方法来解决这些问题。在中国，共享单车未来会走向何方？这由你来决定。
