3.Ididn’tliketheideaofbeingthrownaboutinaboatonaroughsea.

Ving形式既可作动词的宾语,也可作介词的宾语。★Thebirdescaped______________(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形式作宾语。用作定语Theproblembeingdiscussednowisveryimportant.2.Thehousebeingbuiltwillbeourlibraryuponitspletion.用作状语1.Beingaskedtoanswerthequestion,shecouldn’trefuse.2.Havingbeengivensuchagoodchance,howwouldyounotvalueitatall?pareI—Ving一般时和一般时的被动形式;(1)Hehurriedhome,lookingbehindfromtimetotime.(2)Thebuildingbeingrepairedisourdormitory.pareII—Ving的完成时和完成时的被动形式(1)Havingheardthis,ourteacherexpressedhersatisfaction.(2)Havingbeenaskedtostay,Icouldn’tleave.在绝大数情况下，句子的逻辑主语是句中的主语，但有时可有一个名词或代词表示逻辑上的主语，这种带逻辑主语的结构称为独立结构。Themeetingbeingover,wealllefttheroomanddrovehome.会议结束后,我们都离开房间开车走了。Itbeingaholiday,alltheshopswereshut.由于今天是假日，所有商店都关门了。Theheavyfrostingon,deadleaveslaythickontheground.浓霜降临,落叶满地。注意一些动词如need,want,require等作“需要”讲时,其后的动词ing形式的主动语态表示被动意义,也可以用不定式的被动形式来替换。如：Theblackboardneedscleaning.=Theblackboardneedstobecleaned.

Thebrokenwindowwantsrepairing.=Thebrokenwindowwantstoberepaired.

另外注意beworth及beworthy的用法：

Theproblemisworthdiscussing.

Theproblemisworthyofbeingdiscussed.

Theproblemisworthytobediscussed.
