不可以去掉
如果只说"问一个问题"可以直接说ask a question ,但如果后面加副词,就要用out
loud的意思是“大声的、高声的、响亮的”。在动词talk ,speak,shout,laugh等后面,一般用loud,在非正式的谈话中尤其如此
loudly的意思是“高声的”经常可与loud通用。但在较正式语言中即表示“吵嚷不休的噪声”的意味,常用loudly. 例如:1.Don't shout so loud/loudly. 2.When they were arguing,they talked so loudly that the people in the next room could hear every word.
ask out loud, ask loudly
这边的 ask out 就像 speak out 一样,所以out 是不能去掉的。
loud在做副词时:非常吵,声音很大地
He speaks loud and clear.
他说话响亮清楚。
Speak louder and clearer so as to make everyone hear you.
"讲得再响亮点,清楚些,让所有的人都听到。"
loudly在做副词时:响亮地, 大声地
其实没有什么特别的区别!
