14、an not=cant); 3、只有動詞，在動詞原形前加dont；三單動詞前加doesnt, 動詞變回原形。He does his homework. （改成否定句）He doesnt do his homework.一般疑問句: 用Yes或No回答的句子1、有be動詞，be動詞提前；2、有can或would，can或would提前；3、只有動詞，句首加Do/ Does, 動詞用原形；注意：Im 變Are you ; some變any; my變your; and變or .特殊疑問句： 有特殊疑問詞+一般疑問句There be句型提問：1、對數(shù)量提問：1）How many +名詞復(fù)數(shù)+ are
