2011中考英语考前错题本（U字母篇）under［误］Thelakeistwometersundersealevel.［正］Thelakeistwometersbelowsealevel.［析］under的意思是在某物的下面，而below＝lowerthan,即"低于"。［误］Underthehelpofourteacher,allofuspassedtheexam.［正］Withthehelpofourteacher,allofuspassedtheexam.understand［误］Ithinkitisdiffculttomakemyselftounderstand.［正］Ithinkitisdiffculttomakemyselfunderstood.［析］这句话的意思是"我想让别人理解我太难了"。［误］Iamunderstandingthelessonnow.［正］Iunderstandthelessonnow.［析］understand一词没有进行时态。类似的词还有belong,find,hear,love,like等。until［误］Wewalkeduntiltheedgeoftheforest.［正］Wewalkedasfarastheedgeoftheforest.［误］Ourschoolbuscanholduntiltwentychildren.［正］Ourschoolbuscanholduptotwentychildren.［析］until与till两词的意思一样，但两个词都只能用于时间，如：I'llwaituntilIhearfromyou.［误］Iwaitedformymothertoseveno'clock,butshedidn'tcome.［正］Iwaitedformymotheruntilseveno'clock,butshedidn'tcome.［误］CanyoureturnthisbookuntilMonday?［正］CanyoureturnthisbookbyMonday?［析］当我们谈目前正在进行而将来某一时刻才停止的事件时用until，而用by来表达将来某一时刻会发生的动作。［误］Wearrivedhomeuntilitbecamedark.［正］Wedidn'tarrivedhomeuntilitbecamedark.［析］until用于肯定句时表示"某动作直到……为止"，如：Theyworkeduntil5∶00P.M.用于否定句中时意为"直到……才"。所以用于肯定句中要使用延续性动词，但截止性动词却可以用在否定句中。upstairs［误］Hewenttoupstairs.［正］Hewentupstairs.［析］upstairs一词可用作副词，如：Weallhurriedupstairstoseewhathappened.也可用作名词，如；Theupstairsofthehouseneedspainting.同时也可以用作形容词，如：Ahousewiththreeupstairsroomsisquitegood.use［误］Itisnousetoaskher.［正］Itisnouseaskingher.［析］Itisnouse…与Thereisnouse…后通常用动名词，而不用不定式。［误］I'llgetusedtotreatthestudentsthisway.［正］I'llgetusedtotreatingthestudentsthisway.［析］beusedto与getusedto后要接动名词表示"习惯于"做某事。［误］Iusedtogettingupearlyinthemorning.［正］Iusedtogetupearlyinthemorning.［析］usedto表示过去习惯的动作，其后要加动词原形。［误］Oilwasusedtocooking.［正］Oilwasusedtocook.［析］这里的句型虽然也是beusedto但这里不是主动态，而是被动态，所以不能接动名词而应接不定式。［误］WeusedtogototheGreatWallthreetimes.［正］WewenttotheGreatWallthreetimes.［析］usedto只能用来表示一种习惯，而不能用来表达某事发生的次数。
