59

六年级英语改句子技巧可归纳为以下五类,结合权威资料整理如下:

一、句式转换技巧

简单句与复合句转换

- 合并句子:如 "Mike runs fast. I run faster." → "I run faster than Mike."(使用比较级)

- 转换从句:将定语从句改为状语从句(如:They are our women doctors. → Our women doctors are they.)

二、时态与否定句改写

一般现在时否定句

- 有助动词:在动词后加 "not"(如:She doesn't watch TV.)

- 无助动词:在动词前加 "don't/didn't"(如:I can't do it.)

一般疑问句

- 将be动词提前(如:Sarah is 160 cm. → How tall is Sarah?)

- 将情态动词提前(如:Can I watch TV? → Can I?)

三、比较级与特殊句式

比较级表达

- 使用 "比较级+than"(如:My fish is bigger than Mike's.)

- 用 "as...as..." 结构(如:She is as tall as her brother.)

四、疑问词与特殊疑问句

特殊疑问句

- 以疑问词开头(如:When did you go to Shanghai?)

- 对名词/副词提问(如:How heavy is his brother?)

五、同义句与被动语态

同义句转换

- 用 "should/would" 替换 "can"(如:I can help you. → You should help me.)

- 被动语态(如:They are watching TV. → TV is being watched.)

注意事项:

改写时需注意主谓一致、时态统一,避免混淆情态动词与助动词的用法。
