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

Theyalwaysmakeplansfortheirholidays,but,intheend,theyalwaysstayathome.

Hecamewithaplanfor(building)abridgeovertheriver.

3.Thetunnelwouldbewell－ventilatediftallchimneyswerebuiltabovesealevel.if引導(dǎo)的真實(shí)條件句，由于主時(shí)態(tài)是過去，所以相應(yīng)的，主句從句時(shí)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(jì)劃、建議等）”：

Youknowtheywouldn'tacceptyourplan.Whydidyouputitforward?

Hasheputforwardanysuggestion?

5.Hesuggestedthatadoublerailwaytunnelshouldbebuilt.

suggest表示“建議，提出”時(shí)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.

drawin(=takein)吸入、吸進(jìn)

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(gè)事實(shí)，而只是一種假設(shè)或愿望，常伴有if引導(dǎo)的非真實(shí)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(shí)不符。因此，在條件句中要用過去完成時(shí)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(dǎo)的短語相當(dāng)于一個(gè)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(dòng)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(shí)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(shí)，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(shí)條件句和非真實(shí)條件句兩種。真實(shí)條件句所表的假設(shè)是可能發(fā)生和實(shí)現(xiàn)的，是與實(shí)施相符的。E.g.ifitisfinetomorrow,Iwillgotovisitmygrandpa.非真實(shí)條件句所表達(dá)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(shí)相反的情況。IfIwereabird,IwouldflytoAmerica.虛擬語氣在非真實(shí)條件句中1與現(xiàn)在事實(shí)相反IfIwonthelottery,Iwouldbuyanexpensivecar.2與過去事實(shí)相反Ifhehaddrivenmorecarefully,hewouldnothavehadthecaraccidentyesterday.IfIwereyou,Iwouldgiveyoursisterahug.IfIhadtakenyouradvice,Iwouldhavehadabetterfuture.Suggest,demand(要求),order,propose（提議，建議）,insist（堅(jiān)持認(rèn)為），command（命令）,request（要求）,后的賓語從句中：
