句型转换是英语学习中一大难点,很多学生在做这类题时频频出错,下面是我们结合日常学习总结的转换口诀。
一、肯定句变否定句:分两种变化。
1. 找插。
找:如果句子中有系动词(is,am,are,was,were)、情态动词(can, may, must, could, might, shall , should, will, would,, need,)助动词(h**e,has)时,直接在后面插入not。
例:my parents will h**e dinner at seven this evening.直接在will后插入not
my parents will not h**e dinner at seven this evening
2.如果句子中不存在以上词语,要遵循找判分插。
找:找出句中的实意动词。
判:根据实意动词判断句子的时态。
分:将实意动词分成时态标志词和动词原形。
插:在助动词后插入not。
例一:she often watches tv on sundays.
找到实意动词watches
判断时态:一般现在时。
分成时态标志和动词原形does和watch
插入not:在两个词中间插入not,并注意细节变化。
she often watches tv on sundays.
does watch
notshe doesn’t often watch tv on sundays.
