(否定句) ----- Iamnot aboy. (变成一般疑问句)-----Are you aboy? Yes, Iam. No, I’mnot. ②She ismymother.( 变成一般疑问句) -----Is she your mother? Yes, she is. No, she isn ’t. ③This isabook.( 变成一般疑问句) ------Is this abook? Yes, itis. No, itisn ’t. ④These are strawberries.( 变成一般疑问句) ----Are these strawberries? Yes, they are.

No, there isn ’t. 2 (2) 如果是第二类,即含有行为动词的句子(如 like ,have ,play ,eat ,run , need 等)时,要分两步看主语。①I/We/You /They 时,要借助于助动词 do的帮助来变成一般疑问句。即句型为: Do+主语+动词原形+其他?否定句只在动词原形前加 don ’t。例如: ①②③④ Ihave some tomatoes inmybackpack.( 否定句)Idon ’thave any tomatoes inmybackpack. (变成一般疑问句)-----Do you have any tomatoes inyour backpack? Yes, Ido. No, Idon ’t. Weplay sports every day. (否定句) ---We don ’tplay sports every day. (变成一般疑问句)----Do you play sports every day? Yes, wedo. No, we don ’t. ②He/She /It时, 要借助于助动词 does 的帮助来变成一般疑问句。即句型为: Does +主语+动词原形+其他?否定句只在动词前加 doesn ’t,然后将单三还原成原形。 She watches TVevery evening. (否定句)---She doesn ’twatch TVevery evening. (变成一般疑问句)----Does she watch TVevery evening? Yes, she does. No, she doesn ’t. 注意:如果是其他名词的话,在简略回答中要用人称代词来替代,但替代都在第三人称中,即 he, she, it, they 四个中。如: 3 mymother ---she your brother ---- heabook ----it five photos-----they this/that-------it these/those------they myfamily name-----it Tom----he Mary--------she Amy ’ssister -----she some friends------they (3) 如果是第三类情态动词,如 can 时,一般疑问句只将 can 提到句首,否定句将 can 变成 can ’t。同时注意一变二,二变一,三不变,some 变any 。(情态动词不受人称的限制)Ican play basketball.
