on or before the term

The Middle Easterners come on long-term business visas; after buying cheap clothes and hardware in bulk, most jet to Dubai, Baghdad or Tehran before returning for another six months of trade.

这些中东人是持长期商业护照过来的；他们来这里大宗采购便宜的衣服和五金器具，大多数又飞回迪拜，巴格达或者德黑兰，然后半年后再回来做生意。

Investors appear to be trying to get in early on a long-term bet: Emerging-market economies will get back into their grooves long before the U. s. or Europe shake off the global crisis.

投资者似乎是想尽早押注在一个长期前景上：新兴市场经济体恢复最佳状态将远远先于欧美摆脱全球经济危机的时刻。
