5、timid 羞怯的；胆小的，胆怯的
英语解释：shy and nervous; without much confidence; easily frightened
Kieran is a timid child.
露西是个很羞怯的孩子。
6、sheepish 羞怯的；局促不安的；驯服的；胆怯的
She had a rather sheepish smile.
她笑起来非常害臊的样子。
sheep指的是绵羊，含有褒义，可以指害臊而忸怩的人。而goat就常含有贬义，譬如act the goat是干蠢事，old goat是老色鬼。
就像是那个经典的习语：separate the sheep from the goats（分出优劣）。
7、shamefaced 害臊的；惭愧的
英语解释：awkward and embarrassed or ashamed
Do not be so shamefaced. Youll do it very well.
别那样脸皮薄，你会做得非常不错的。
He looked somewhat shamefaced when he realized his mistake.
他认识到我们的错误后，看起来有的惭愧。
容易混淆的shame同根词：
①shameful1可耻的，丢脸的
I couldnt see anything shameful in what I had done.
我觉得我没干什么丢脸的事。
②ashamed羞耻的，羞愧的；不好意思的，难为情的
Youve got nothing to be ashamed of.
你没什么可感到内疚的。
③shameless无耻的，不要脸的
She is completely shameless about her ambition.
她对我们的野心全然不知羞耻。
8、blushing 脸红的
From a merry child, then a blushing maid, she has become a perfect woman now.
从一个纯真无邪烂漫的孩子，到一个害羞害臊的女孩，她目前已长成一个姿容出众的女子。
我想大伙都了解，blush可以做名词和动词，表示脸红。有时候大家脸红，其实也是由于害臊嘛。
I blush to think of what a fool I made of myself.
一想到我出了那样大洋相我就脸红。
