②、Does he go to school in the morning?
③、Where does he go in the morning?she dustedthecupboardjust now劃線部分是dustedthecupboard否定句一般疑問句對(duì)劃線部分提問sam has a new car否定句一般疑問句對(duì)劃線部分提問劃線部分是a new cartom has been to shanghai several times 否定句一般疑問句對(duì)劃線部分提問劃線部分是 several times 用how ofter提問they did their homework after dinner否定句一般疑問句對(duì)劃線部分提問劃線部分是 after dinner這位童鞋不要偷懶哦，明白其中的道理才是關(guān)鍵。仔細(xì)看這幾道題的結(jié)構(gòu)很相似，變成否定句的話，是在實(shí)義動(dòng)詞（be動(dòng)詞、系動(dòng)詞）后面加not；變成一般疑問句是把Do提前，（若為Does，則還要把實(shí)義動(dòng)詞變成原形），句子的語序不變；對(duì)劃線部分提問時(shí)，則要根據(jù)句意，適當(dāng)?shù)倪x用where、what、when、how、how often等。不知道你能看明白否？如果你還是不確定，你可以自己做好那幾道題的答案，發(fā)上來給我看！我只是想對(duì)一下答案罷了，看看看有沒有錯(cuò)的，答案是Samdoesnt have a new car does sam have a new car ?what does sam have ? Tom hasn't been to Shanghai several times.Has Tom been to Shanghai several times?How often has Tom been to Shanghai?What did she do just now?They didn't do their homework after dinner智能打這么多字了第一個(gè)完全正確；第二個(gè)應(yīng)該是題目的問題（has gone to該比較現(xiàn)實(shí)吧，而且我覺得念for several times 比較順）；第三個(gè)疑問句是：Did they do their homewotk after dinner?提問句是：When did they do their homework?看一下我上一個(gè)的解析，不知道能否幫到你？你是英語老師嗎
