twenty－one－mile作tunnel的修飾語，注意mile為單數(shù)。planfor+名詞／動名詞表示“……的計劃”：

Theyalwaysmakeplansfortheirholidays,but,intheend,theyalwaysstayathome.

Hecamewithaplanfor(building)abridgeovertheriver.

3.Thetunnelwouldbewell－ventilatediftallchimneyswerebuiltabovesealevel.if引導的真實條件句，由于主時態(tài)是過去，所以相應(yīng)的，主句從句時態(tài)也發(fā)生了變化。主將主過將從現(xiàn)從過e.g.WhenIwasyoung,IthoughtifIhadalotofmoney,Iwouldgoabroad

4.In1860,abetterplanwasputforwardbyanEnglishman,WilliamLow.

putforward為固定短語，可分開用，其含義之一是“提出（計劃、建議等）”：

Youknowtheywouldn'tacceptyourplan.Whydidyouputitforward?

Hasheputforwardanysuggestion?

5.Hesuggestedthatadoublerailwaytunnelshouldbebuilt.

suggest表示“建議，提出”時有兩種句型：

a)suggeststh.(tosb.)或suggestdoingsth.（向某人）建議某事，建議干某事：

Hesuggestedadifferentplan.

Hesuggesteddoingitinadifferentway.

b)suggestthatsomeone(should)dosomething/thatsomething(should)bedone建議某人干某事/建議干某事：

Isuggestthatweshouldgohomeimmediately.

Hesuggestedthatthedoctorshouldbecalledin.

6.Thiswouldsolvetheproblemofventilation,forifatrainenteredthistunnel,itwoulddrawinfreshairbehindit.

drawin(=takein)吸入、吸進

7.If,atthetime,theBritishhadnotfearedinvasion,itwouldhavebeencompleted.

這是英語中的虛擬語氣。虛擬語氣所表述的不是一個事實，而只是一種假設(shè)或愿望，常伴有if引導的非真實條件句。以上的這句話是對大戰(zhàn)期間所發(fā)生的事情的一種假設(shè)，而這種假設(shè)與事實不符。因此，在條件句中要用過去完成時hadnotfeared，而主句中則要用

would+have+過去分詞。E.g.Igotuplatethismorning,soImissedthetrain.IfIhadnotgotuplate,Iwouldn'thavemissedthetrain

10.ItwasofficiallyopenedonMarch7,1994,finallyconnectingBritaintotheEuropeancontinent

現(xiàn)在分詞connecting引導的短語相當于一個并列分句。connect表示“連接”、“連結(jié)”，可與to或with連用：

Thisroadconnectsthewillagewith/toLondon.

Thelakeandthecanalareconnectedbyariver.

語法講解語氣：英語動詞有三種語氣：陳述語氣，祈使語氣和虛擬語氣。1：陳述語氣：用來表示所說的話是事實或者提出疑問，廣泛用于陳述句，疑問句和感嘆句。2：祈使語氣：表示所說的話是請求，命令，指示或者勸告。虛擬語氣虛擬語氣：1.表示所說的話不是事實，而是一種假設(shè)，猜測，懷疑等。（在條件從句或者讓步狀語從句中）2：一種表示說話人的愿望，要求，命令，建議等（在賓語從句，表語從句，同位語從句）虛擬語氣在條件狀語從句中的用法條件句有真實條件句和非真實條件句兩種。真實條件句所表的假設(shè)是可能發(fā)生和實現(xiàn)的，是與實施相符的。E.g.ifitisfinetomorrow,Iwillgotovisitmygrandpa.非真實條件句所表達的假設(shè)則不可能或不大可能發(fā)生或?qū)崿F(xiàn)的，與事實相反的情況。IfIwereabird,IwouldflytoAmerica.虛擬語氣在非真實條件句中1與現(xiàn)在事實相反IfIwonthelottery,Iwouldbuyanexpensivecar.2與過去事實相反Ifhehaddrivenmorecarefully,hewouldnothavehadthecaraccidentyesterday.IfIwereyou,Iwouldgiveyoursisterahug.IfIhadtakenyouradvice,Iwouldhavehadabetterfuture.Suggest,demand(要求),order,propose（提議，建議）,insist（堅持認為），command（命令）,request（要求）,后的賓語從句中：
