3.Ididn’tliketheideaofbeingthrownaboutinaboatonaroughsea.

Ving形式既可作動詞的賓語,也可作介詞的賓語?！颰hebirdescaped______________(catch).★Hewasafraidof_______________(abandon)byus.注意在avoid,admit,appreciate,plete,consider,delay,enjoy,escape,excuse,finish,forgive,imagine,mind,miss,practise,risk,suggest,giveup,putoff,feellike,insiston等后只接Ving形式作賓語。用作定語Theproblembeingdiscussednowisveryimportant.2.Thehousebeingbuiltwillbeourlibraryuponitspletion.用作狀語1.Beingaskedtoanswerthequestion,shecouldn’trefuse.2.Havingbeengivensuchagoodchance,howwouldyounotvalueitatall?pareI—Ving一般時和一般時的被動形式;(1)Hehurriedhome,lookingbehindfromtimetotime.(2)Thebuildingbeingrepairedisourdormitory.pareII—Ving的完成時和完成時的被動形式(1)Havingheardthis,ourteacherexpressedhersatisfaction.(2)Havingbeenaskedtostay,Icouldn’tleave.在絕大數(shù)情況下，句子的邏輯主語是句中的主語，但有時可有一個名詞或代詞表示邏輯上的主語，這種帶邏輯主語的結構稱為獨立結構。Themeetingbeingover,wealllefttheroomanddrovehome.會議結束后,我們都離開房間開車走了。Itbeingaholiday,alltheshopswereshut.由于今天是假日，所有商店都關門了。Theheavyfrostingon,deadleaveslaythickontheground.濃霜降臨,落葉滿地。注意一些動詞如need,want,require等作“需要”講時,其后的動詞ing形式的主動語態(tài)表示被動意義,也可以用不定式的被動形式來替換。如：Theblackboardneedscleaning.=Theblackboardneedstobecleaned.

Thebrokenwindowwantsrepairing.=Thebrokenwindowwantstoberepaired.

另外注意beworth及beworthy的用法：

Theproblemisworthdiscussing.

Theproblemisworthyofbeingdiscussed.

Theproblemisworthytobediscussed.
