比较级的变化,一般词尾加er。
加的方法有四种,我们一起学习它。
一般情况直接加:smaller, stronger属于它;
结尾有e去e加:nicer, later属于它;
辅y结尾改i加: heavier, easier属于它;
一辅重读闭音节,末尾字母要双写:bigger, thinner属于它。2. 形容词比较级的读音
(1)形容词在变为比较级之后,通常增读/?(r)/。
例如:lower /l???(r)/
(2)如果原级中的尾音是辅音音素,那么这个辅音音素就要
与/?(r)/相拼。
例如:older /??ld?(r)/
(3)有些辅音字母在形容词原级中没有单独发音,但在比较
级中却有了自己的发音。
例如:young /j??/ — younger /j??ɡ?(r)/一、写出下列句子中形容词的比较级。
