(1)atthetime=atthemomentwhensomethinghappened(2)themurderwascommitted能够看作是定语从句修饰time,而假如前面词假如是thetime,themoment,theway等做先行词时候，后面关系副词是能够省略掉。第15页2.'Doyoualwayscatchsuchanearlytrain?'askedtheinspector.catchatrain乘火车，catchabuseg.Ifwecomehere10minutesearlierwillcatchthetrain(bus).假如我们能早到10分钟我们就能赶上火车(汽车).catchyoulater=再见such+n./名词短语so+adj./adv.suchanearlytrainsoearlyatrain第16页3.'OfcourseIdo,'answeredtheman.'Imustbeatworkat10o'clock.MyemployerwillconfirmthatIwasthereontime.'

Idon'tthinkso.Idon'tsupposeso.Idon'texpectso.waitforsb/sth等候某人、某物第19页6..Andyoudidn'tnoticeanythingunusual?莫非你没有注意到有什么异常情况？这是由陈说句后加问号表示问句。anything/something等被adj.修饰时，adj.在不定代词后eg.I'dlikesomethingcheaper.第20页7..youarenottellingthetruth.你没有说实话。tocallaspadeaspade.实话实说Let'scallaspadeaspade.让我们实话实说吧！第21页8.Isuggestthatyoudidnotcatchthe8o'clocktrain,but...suggest提醒，暗示：Itsuggestedthatyoudidn'tdowellinyourfinalexam.这表明你期末考试考并不好。suggest提议，注意用虚拟语气：Isuggestthathegotothehospitaltohaveabodyexamination.我提议他去医院进行一次体检。第22页9.ItbrokedownatFerngreenstationandwastakenofftheline(1)breakdown抛锚，出故障Thecarbrokedowninthemiddleofthetrip.汽车在旅途中途抛锚了.(2)betakenofftheline取消航线Duetothebadweather,alltheplanestothisareaweretakenofftheline.因为天气不好,全部来这个地域飞机都改变了航线第23页yousee在口语中经常作为插入语出现，句首、句中或句尾均能够，表示“你知道，实际上”等含义：你知道，我腿还没好呢，所以我不能和你去爬山了。Mylegisn’tallrightyet,yousee,soIcan’tclimbthehillwithyou.run能够指火车、公共汽车、船等“定时/定时行驶，（在两地间）往来”：这个船在Dover和Calais之间往来ThisshiprunsbetweenDoverandCalais.第24页Grammar-Indirectspeech引述他人话时，普通采取两种方式：一是引用他人原话，把它放在引号内，称为直接引语；二是用自己话加以转述，被转述话不放在引号内，称为间接引语。间接引语在大多数情况下是一个宾语从语。直接引语变成间接引语时，要注意以下几点：人称改变、时态改变、宾语从句要用陈说句语序。

1.直接引语是陈说句，变成间接引语时，由连词that引导。比如：

Shesaid,"Iamveryhappytohelpyou."→

Shesaidthatshewasveryhappytohelpyou.第25页2.直接引语是普通(选择/反意)疑问句，变成间接引语时，由连词whether或if引导。比如：Heaskedme,"Doyoulikeplayingfootball?"→Heaskedmeif/whetherIlikedplayingfootball.注意：大多数情况下，if和whether能够交换，但后有ornot,或在动词不定式前，或放在介词后作连接词时，普通只用whether。比如：

Sheaskedmewhetherhecoulddoitornot.

Hehesitatedaboutwhethertodriveortakethetrain.第26页3.直接引语是特殊疑问句，变成间接引语时，由对应疑问词who,whom,whose,how,when,why,where等引导。比如：

Mysisteraskedme,"Howdoyoulikethefilm?"→

MysisteraskedmehowIlikedthefilm.第27页4.直接引语是祈使句，变成间接引语时，把动词原形变成动词不定式，并在动词不定前加tell,ask,order等宾语。比如：

Theca
