She is looking at some pictures.
現(xiàn)在進行時的結(jié)構(gòu)是 be+doing,英語語法中沒有be+do結(jié)構(gòu).Are the boy drawing a dog?改錯像我剛才講的，英語語法中沒有be+動詞原形結(jié)構(gòu)They are have a cake. 首先判斷時態(tài)，他們正在吃蛋糕。用現(xiàn)在進行時態(tài)，結(jié)構(gòu)為be+doing, 所以應改為They are having a cake.現(xiàn)在進行時態(tài)變否定句應在be動詞后加not而非no，所以第二句改為I am not playing a game.be動詞的選擇應該根據(jù)主語的單復數(shù)進行，第三句主語為 the boy，單數(shù)，所以be動詞應用is，變一般疑問句講be動詞提前，所以第三句改為 Is the boy drawing a dog?The dog is running after the boy. 這句話從語法角度講沒有問題第五句Sarah playing computer games now.還是要看的是進行時態(tài)的結(jié)構(gòu)，應該是be+doing，二者缺一不可，所以應該為 Sarah is playing computer games.第六句 I have lunch with my parents.應譯為 我正在跟我父母吃午飯，用現(xiàn)在進行時，應該為 I am having lunch with my parents.
