第3頁省略規(guī)則．當從句主語和主句主語一致(或者從句主語為it)．

從句謂語中包含be動詞第4頁重難點解析哪些謂語結(jié)構(gòu)中包含be動詞？被保留部分是什么？.

5.Hewasaswimmerwhenhewasachildbetodotosaysomething主系表necessary主系表achild第6頁進行時結(jié)構(gòu)：bedoing,被動語態(tài)：bedone,未來時:betodo,主系表結(jié)構(gòu)：be+名詞/形容詞（短語）/介詞短語所以在省去從句主語和be動詞．保留be之后部分，被保留部分常為現(xiàn)在分詞、過去分詞、不定式、形容詞等。經(jīng)過以上例句我們能夠總結(jié)出含有be動詞結(jié)構(gòu):第7頁尤其關(guān)注

若從句主句是it或與主句主語相同，且在謂語中含有be時，常省略從句主語和be。

被保留部分常為現(xiàn)在分詞、過去分詞、不定式、形容詞等。第8頁1._____________________(在北京時候),IpaidavisittotheSummerPalace.2.______________________(當是個年輕人時候),AbrahamLincolnwasastorekeeperandapostmaster.3.Hehasnomoney.______(要是有話),hewillgiveus.4._____________(除非修理),themachineisofnouse.5._______________________(要是給更多關(guān)注),Theboycouldhaveturnedoutbetter.6.Agirlstoodatthegateoftheschoolasif______________________________(跟老師講話).When/Whilein
