(1)“With...homes”為“with+賓語+賓語補足語”的復(fù)合結(jié)構(gòu)，此處是動詞不定式短語作賓語補足語。

(2)havenochoice/alternativebuttodosth.除了做某事之外別無選擇donothingbutdosth.只是做某事havenothingtodobutdosth.無事可做，只有做某事thereisnothingtodobutdosth.無事可做，只有做某事11.What'smore,hungryanimalsarefindingplentytoeatinourgardensandintheleftoverswethrowaway.

本句為主從復(fù)合句。What'smore為插入語；toeat為動詞不定式作后置定語，修飾plenty；wethrowaway為省略關(guān)系詞that/which的定語從句，修飾先行詞leftovers。12.Thereisevidencethaturbanracoonsaremoreintelligentthantheirwildcousins,as

本句為主從復(fù)合句?！皌hat...cousins”為that引導(dǎo)的同位語從句，解釋說明evidence；“as...inthewild”為as引導(dǎo)的原因狀語從句，其中包含一個which引導(dǎo)的定語從句，修飾先行詞othercontainers。15.Theircitylocationalsomeansthattheyaregettingatasteforthemulticulturalcuisineonofferfromthegarbage,suchashamburgers,lambkebabsandevengarlicbread!

城市的位置也意味著，它們可以吃到來自垃圾里的多元文化的菜肴，比如漢堡包、烤羊肉串甚至蒜蓉面包!

特別提示：amountsof/anamountof尤與不可數(shù)名詞連用。作主語時，謂語動詞的數(shù)與amount的數(shù)保持一致。

e.g.Largeamountsofmoneywerespentonbuildingthebridge.大量的資金用于建造這座橋。There'sonlyasmallamountoffood.只有一點兒食物。18.Onetheorybehindthisisthatthesebirdshaveyettochangetheirmigratoryroutesthattakethemthroughcitieswithhigh-risebuildings.一種理論認為，這些鳥類的遷徙路線讓它們穿過這些有高樓大廈的城市，而它們還沒有調(diào)整路線。

第一個that引導(dǎo)表語從句；第二個that引導(dǎo)定語從句，修飾theirmigratoryroutes。19.Howevertheyadapttoourwaysofurbanliving,it'simportantthatwegetabetterunderstandingofandevenlearntoappreciateourwildneighbours.不論它們?nèi)绾芜m應(yīng)我們的城市生活，更好地理解甚至學(xué)會欣賞我們的野生鄰居是非常重要的。

looktowardsharmoniouslysharingoururbanhabitats.只有那時，我們才能展望與它們和諧分享城市棲息地的未來。

(1)only放在句首修飾狀語時，主句采用部分倒裝的形式。如果only后接的不是狀語，而是主語，主句可以不用倒裝。

e.g.Onlythosewhohadbookedonlinewereallowedin.

只有那些在網(wǎng)上訂了票的人可以進去。如果only后接的是賓語，主句可以倒裝，也可以不倒裝。

e.g.Onlyhismotherhewillob
