17精选课件pptThebasicjobofthesuspensionsystemistoabsorbtheshockscausedbyirregularroadsurfacesthatwouldotherwisebetransmittedtothevehicleanditsoccupants,thushelpingtokeepthevehicleonacontrolledandlevelcourse,regardlessofroadconditions.难点提示：1）thatwouldotherwisebetransmittedtothevehicleanditsoccupants是shocks的定语从句；2）thushelping…现在分词短语作主句的状语，并非定语从句的构成部分；3）tokeepthevehicleonacontrolledandlevelcourse不定式短语的含义是“使汽车保持在可以控制的、笔直的行驶路线上。”参考译文：悬架系统的基本作用是吸收路面不平引起的冲击和振动，使其不会传递给车辆和乘员，这样，不管路况如何，都能使车辆具有可控制的、笔直的行驶路线。难点分析18精选课件pptThesteeringsystemprovidesthemeansbywhichthefrontwheelsaredirectionallyturned.Thesteeringsystemmaybepowerassistedtoreducetheeffortrequiredtoturnthesteeringwheelandmakethevehicleeasiertomanoeuvre.
