5outrace超越【教材原文】Jimmy,expertthoughhewas,couldn’toutraceRobutt,whodidn’tneedaspacesuit,andhadfourlegsandtendonsofsteel.论速度，吉米虽然是个能手，但他比不过罗布特，因为他有四条腿和钢铁作的肌腱，还不用穿太空服。6Jimmycouldn’tgowrongwhileRobuttwasaround,trippinghimwhenhewastooneararock,orjumpingonhimtoshowhowmuchhelovedhim,orcirclingaroundandsqueakinglowandscaredwhenJimmyhidbehindarock,whenallthetimeRobuttknewwellenoughwherehewas.Paraphrase:JimmywasalwayssafewhileRobuttwaswithhim.Robuttwouldknockhimoutoftroublewhenhewastooneararock,jumponhimtoshowhowmuchhelovedhim,orgoroundincirclesmakingnoisesasifhewasscaredwhenJimmyhidbehindarock.RobuttalwaysknewverywellwhereJimmywas.trip意为tomakesomeonefallbyputtingyourfootinfrontofthemwhentheyaremoving“把（某人）绊倒”，例如：Hedidn’tnoticemeandstretchedouthisfootsuddenly,almosttrippingme.7JimmyheldouthisarmsandRobuttwasintheminonebound.Paraphrase:WhenJimmyopenedhisarms,Robuttjumpedintothematonce.holdout意为“伸出（手或手里的东西）”。例如：Sheheldoutherhandtohim.bound是一个多义词，在本句中用作名词，意为alongorhighjumpmadewithalotofenergy“跳跃”。(1)adj.一定会；很可能会boundtodo/besth.(2)受（法律、义务或情况）约束（必须做某事）；有义务（做某事）boundbysth.todosth.例如：Youareboundbythecontracttopaybeforetheendofthemonth.(3)v.&n.跳跃8IloveRobuttandthat’swhatcounts.Paraphrase:IloveRobutt,andthatisthemostimportantthing.count是一个多义词，在本句中用作动词，意为tobeimportantorvaluable“重要”。例如：Whatreallycountsiswhether
