1·It's a sign that what probably ignited the houses was not burning trees or chaparral; instead, the houses touched off one another as embers blew like wind-borne viruses.
由此可见，房子失火并不可能由燃烧的树木或灌木丛造成，而是由余烬引起。
2·The Nine Peaks in Songjiang are the only natural hills in Shanghai. Green trees amid the hills and red-roofed houses set off one another, with dense forests covering in the surface of the hills.
松江九峰是上海唯一一处自然山丘，山间绿树红楼掩映，山体表面林木深秀。
3·It is an open industry secret that some Chinese trading houses take risky bets that play prices of one market off those of another, and structure deals that allow foreign firms to do the same.
中国一些从事期货交易的公司在市场上下高风险赌注已经是业内公开的秘密，这种交易就是利用两个市场在价格上的不同步而渔利。它们还通过一些交易使外国公司也能从事这种套利活动。
