1·There are streets where nothing stands, corners where one house or one wall has survived, everything around it is matchwood.
那儿的街道上已经什么都没有了，街角偶尔会有一栋房子或一堵墙立在那里，四周的一切都是碎片。
2·Learning how to safely harness the invisible, odorless resource took some time. Many a building was blown to matchwood because of leaking gas. In 1908, a mattress factory exploded.
学习如何安全使用这种无形、无味的资源需要时间。很多建筑因为漏气而被炸成碎片。1908年，一家床垫厂发生爆炸。
