否定句 I don't want to give the book to (her).
一般疑問(wèn)句 Do you want to give the book to (her)?Yes ,I do.No,I don't
who (Whom) do you want to give the book?為什么要加do?不加其他的？這是個(gè)動(dòng)詞一般現(xiàn)在時(shí)的句子，變成否定句，一般疑問(wèn)句，特殊疑問(wèn)句時(shí)，要加助動(dòng)詞“do", 不能用 is，are 等等。以后還要學(xué)習(xí)動(dòng)詞的其它形式，句子變形都要加助動(dòng)詞，如：動(dòng)詞第三人稱單數(shù)要加 does, 過(guò)去時(shí)要用 did 等等。
