2022-2023学年人教版八年级英语下册完成句子解题技巧以及重点题型

八下完成句子重点题型 1、 改为否定句或一般疑问句 (注意some变any， 否定句both and 变为neither nor ，too 变为either，already 变yet) （1.）首先看句子有没得be动词（am, is, are,was,were）,以及情态动词should,如果有，变否定在be动词或情态动词后加not ，变一般疑问句把be动词或情态动词提前。（注意缩写isn’t= is not wasn’t=was not weren’t=were not should not = shouldn’t） 1. You should take her to see a dentist. You ______ ________ take her to see a dentist. 2. Tom was sleeping at this time last night. Tom ______ _______ at this time last night. 3 I was having my breakfast at half past six yesterday morning. (改为一般疑问句) _______ you ______ your breakfast at half past six yesterday morning? （2 ）如果句子含有have/has +动词的过去分词ed,那么是现在完成时态， 变否定在have/has 后面加not （注意缩写haven’t、 hasn’t） 后面动词过去分词不变，肯定句的already 要变 yet 放在句尾。 注意：现在完成时态容易和一般过去时态混淆。一般过去时态谓语动词是动词过去式。 现在完成时态也容易和一般现在时态混淆。如：She has had lunch. She had lunch just now. She has lunch at 12:00 every day. 1 Lucy has already seen this film.变否定句 Lucy ______ seen this film ________. 2 He read some famous stories last month.（改为一般疑问） ______ he read _______ famous stories last month? 3 My mother used to be a teacher.(改成否定句) My mother _______ _______ to be a teacher. 二 对划线部分提问 1 当划线部分是is+V-ing /was + V-ing/are+V-ing/were +V-ing 划线提问的题型，一律用What…doing…?
