3. But for exasperated drivers, help may be at hand in the shape of a satnav system that understands a driver’s emotions and adjusts its behaviour accordingly. 对于愤怒的司机来说，帮助或许就在身边的卫星导航系统的模型中，它能够理解司机的情绪，适当地调节它的运行状况。
4. To create electricity for our modern AIDS - GPS, EPIRB, AIS, Satnav and so forth - we have four solar panels, a wind generator and a foot pump, which will also serve as exercise equipment. 为了给筏子上的现代小工具提供电力——卫星导航仪，应急无线电标识，船舶自动识别仪等——我们准备了四块太阳能电池板，一架风力发电机和一部兼作健身器的脚踏泵。
5. I recently saw a newspaper advert for a satnav-capable mobile phone, the strapline for which was something along the lines of: "Now you'll always be able to find the pub your mates are drinking in." 我最近看了一则报纸上关于带卫星导航功能的手机广告，副标题大概是“现在您能找到您伴侣正在喝酒的酒吧。”
