聽英語磁帶和看英文電影是學習英語的好方法。

Finding單數(shù)復數(shù)2.it在句首作形式主語，動詞-ing形式后置作真正的主語，用形容詞或名詞作表語。nouse,nogood,fun,hardwork,ahard/difficultjob,awasteoftime常見的名詞或名詞短語

dangerous,worthwhile,useless常見的形容詞

it作形式主語的常見句型：It+is+awasteoftimedoing做……是浪費時間的Itisnogood/use/fundoing做……是沒用處的Itisuseless/usefuldoing

madehermotherupset.

visiting

sickpeoplewasadutyandapleasure．四.動詞-ing形式與不定式做主語的比較還是個孩子的時侯,她就覺得探視病人是一種責任,也是一種愉悅。2)Hesaid,“Togoonlikethisisuseless.”他說:“繼續(xù)這樣下去是無用的?！?)Doingnothingisdoingevil．什么也不做就是作惡。4)It’sanhonorformetobeinvitedtotheparty.我很榮幸被邀請參加這個晚會。Fillineachblankusingthe-ingformofaverbfromtheboxandstateitsfunction.Onewordwillbeusedtwice.combine/cover/grow/take/limit/walk/experienceXixiNationalWetlandPark,_____________10squarekilometresinwesternHangzhou,isthefirstnationalwetlandparkinChina.____________citylife,nature,andwetlandsmakestheparkapopulardestinationbothfortouristsandlocalresidents.AtXixi,___________aboattour,___________alongpaths,and___________localcustomsandtraditionsofthevillagesinthisparkareatthetopof
