形容词变副词的规则：
1.一般情况下直接加“ly”,如quick---quickly 2.以“y”结尾的,先将“y”改成“i”,再加“ly”,如happy---happily
少数以e结尾的形容词,要去掉e再加-ly;例如：true-truly等;
但绝大多数以e结尾的形容词仍然直接加-ly;例如：polite-politely, wide-widely等;
形容词变副词通常是加ly,其变化有规律可循,请记住以下口诀：
一般直接加,“元e”去e加,“辅y”改i加,“le”结尾e改y;
分别举例如下：
quick—quickly,
true—truly,
happy—happily,
possible—possibly.
另外：
一、在形容词词尾直接加-ly;如:real-really; helpful-helpfully; careful-carefully; hopeful-hopefully; slow-slowly; quick-quickly; quiet-quietly
二、以加y结尾的形容词要变y为i,然后再加-ly;如:busy-busily; angry-angrily; easy-easily
三、某些以加不发音的字母e结尾和以-ue结尾的形容词要先去掉e,然后再加-y或-ly;如: terri
ble-terribly; true-truly; gentle-gently
另外,副词还可以由形容词加前缀a-得来,如:loud adj.-aloud adv.
此外,部分名词加后缀也可变成副词,如:part-partly;
例句: It is partly her fault. 有部分是她的错;
需注意: friendly; motherly; lovely等词是形容词而非副词;
再看转化副词;在英语中,有些词既可以作形容词,又可以作副词,如early, much, fast, little, wide, loud等; 由于这类词词性虽不同,但词形却一样,这就需要大家学会在特定语境中判断它们各自的词性;例句:Thank you very much. adv. 多谢;There is much water in the river. adj. 河里有很多水;The music is too loud. Please turn it down. adj. 音乐声太大,请调低点;He speaks loud enough. So everyone in the room can hear what he said. adv. 他说话的声音很大,所以房间里每个人都能听到他的话;
