twenty－one－mile作tunnel的修饰语，注意mile为单数。planfor+名词／动名词表示“……的计划”：

Hecamewithaplanfor(building)abridgeovertheriver.

3.Thetunnelwouldbewell－ventilatediftallchimneyswerebuiltabovesealevel.if引导的真实条件句，由于主时态是过去，所以相应的，主句从句时态也发生了变化。主将主过将从现从过e.g.WhenIwasyoung,IthoughtifIhadalotofmoney,Iwouldgoabroad

4.In1860,abetterplanwasputforwardbyanEnglishman,WilliamLow.

putforward为固定短语，可分开用，其含义之一是“提出（计划、建议等）”：

Youknowtheywouldn'tacceptyourplan.Whydidyouputitforward?

Hasheputforwardanysuggestion?

5.Hesuggestedthatadoublerailwaytunnelshouldbebuilt.

suggest表示“建议，提出”时有两种句型：

a)suggeststh.(tosb.)或suggestdoingsth.（向某人）建议某事，建议干某事：

Hesuggestedadifferentplan.

Hesuggesteddoingitinadifferentway.

b)suggestthatsomeone(should)dosomething/thatsomething(should)bedone建议某人干某事/建议干某事：

Isuggestthatweshouldgohomeimmediately.

drawin(=takein)吸入、吸进

7.If,atthetime,theBritishhadnotfearedinvasion,itwouldhavebeencompleted.

这是英语中的虚拟语气。虚拟语气所表述的不是一个事实，而只是一种假设或愿望，常伴有if引导的非真实条件句。以上的这句话是对大战期间所发生的事情的一种假设，而这种假设与事实不符。因此，在条件句中要用过去完成时hadnotfeared，而主句中则要用

would+have+过去分词。E.g.Igotuplatethismorning,soImissedthetrain.IfIhadnotgotuplate,Iwouldn'thavemissedthetrain

10.ItwasofficiallyopenedonMarch7,1994,finallyconnectingBritaintotheEuropeancontinent

现在分词connecting引导的短语相当于一个并列分句。connect表示“连接”、“连结”，可与to或with连用：

Thisroadconnectsthewillagewith/toLondon.

Thelakeandthecanalareconnectedbyariver.

语法讲解语气：英语动词有三种语气：陈述语气，祈使语气和虚拟语气。1：陈述语气：用来表示所说的话是事实或者提出疑问，广泛用于陈述句，疑问句和感叹句。2：祈使语气：表示所说的话是请求，命令，指示或者劝告。虚拟语气虚拟语气：1.表示所说的话不是事实，而是一种假设，猜测，怀疑等。（在条件从句或者让步状语从句中）2：一种表示说话人的愿望，要求，命令，建议等（在宾语从句，表语从句，同位语从句）虚拟语气在条件状语从句中的用法条件句有真实条件句和非真实条件句两种。真实条件句所表的假设是可能发生和实现的，是与实施相符的。E.g.ifitisfinetomorrow,Iwillgotovisitmygrandpa.非真实条件句所表达的假设则不可能或不大可能发生或实现的，与事实相反的情况。IfIwereabird,IwouldflytoAmerica.虚拟语气在非真实条件句中1与现在事实相反IfIwonthelottery,Iwouldbuyanexpensivecar.2与过去事实相反Ifhehaddrivenmorecarefully,hewouldnothavehadthecaraccidentyesterday.IfIwereyou,Iwouldgiveyoursisterahug.IfIhadtakenyouradvice,Iwouldhavehadabetterfuture.Suggest,demand(要求),order,propose（提议，建议）,insist（坚持认为），command（命令）,request（要求）,后的宾语从句中：
