小议含有特定词的肯定句转化为否定句.doc

小议含有特定词的肯定句转化为否定句目前英语句型转换题对学生来说确实是一个难题。由肯定句变为否定句, 一般只加not就可以了。但句中含有特定词改为否定句时，也应做相应的变化，现就自己在教学中的总结和归纳做一简单说明。1. 肯定句中too, also 要相应改为either.E.g: He is a doctor, too. -He isnt a doctor, too. He also asked you to go. -He didnt ask you to go, either.2. 肯定句中的不定代词both 要改为neither, all 要改为none, every 要改为no, everything 要变为nothing 或 anything. E.g: 1).Both of them went to the cinema.-Neither of them went to the cinema. 2).He knows all the comrades.-He knows none of the comrades. 3). Every student can answer it.-No student can answer it. 4). Everything is ready.-Nothing is ready. / Anything isnt ready.3. 肯定句中的nearly 要改为hardly：E.g: He nearly finishes his work.- He hardly finishes his work.He nearly saw everything.- He hardly saw anything.4. 肯定句中的always 要改为never.E.g: He always comes to school early. -He never comes t school early.5. 肯定句中的already 要改为yet.E.g: He has already been to Beijing.- He hasnt been to Beijing yet.6. 肯定句中的often 要改为seldom.E.g: The boys often play basketball.- The boys seldom play basketball.7. 肯定句中的still 要改为not.any longer / no longer.E.g: He is still in bed. -He isnt in bed any longer. / He is no longer in bed.8. 肯定句中的both.and要改为neither.nor.E.g: Xiao Li speaks both English and French. Xiao Li speaks neither English nor French.9. 肯定句中的 and 要改为 or.E.g: He has brothers and sisters. - He has not any brothers and sisters./ He has no brothers or sisters.* 综上所述, 上面有些特定词在改为否定句时, 变化后的特定词基本上为自身否定词表示否定意义.E.g: both - neither, all - none, everything - nothing, nearly - hardly,always -
