4、搭配：aloud作“出聲地”解時主要與read, think等連用，作“大聲地”時主要與call, shout, cry等連用；而loud主要與talk, speak, sing, laugh等連用；loudly則可與任何發出聲響的動詞如bring, explode, knock和insist, demand, explain等連用。例如：（1）Please read aloud so that I can here you. 請大聲朗讀，這樣我才能聽見。（2）The newspaper might just as well talk loud about as anything else. 報紙也可能象對付別的事情一樣把這件事高談闊論。（3）Don"t knock loudly.不要大聲敲門。
5、句中的位置： loud和aloud只能用在動詞後面; 而loudly則既可用在動詞後,也可用在動詞前。例如：As we walked in the dark street, we sang songs and talked loudly.當我們在黑洞洞的街上走路時我們高聲地唱歌說話。
這三個詞的共同含義是“大聲地”,其區別是：
1、詞性：aloud和loudly只能用作副詞；而loud既可用作副詞，又可用作形容詞。例如：Don"t mak those loud noises.不要在那大聲喧譁了。
2、含義： loud和loudly只指“大聲地”“高聲地”; 而aloud除指“大聲地”外，還可指“出聲地”。另外loudly還暗含嘈雜喧鬧的意味。例如：She never talked too loudly of earls and countesses.她從來沒有過份高聲地談到伯爵和伯爵夫人。
3、詞形變化： aloud沒有比較級和最高階；而loud和loudly則具有比較級和最高階形式,例如：I can"t hear you, please speak louder.我聽不見你的聲音，請大聲點。
