Describing someone who has no idea that something bad is coming — they trust the situation, and that trust is about to be used against them. The key is that the reader or listener knows the danger and the person does not, so the word creates a small feeling of dread or pity.

Describing someone用來形容某人who has no idea完全不知道that something bad is coming有壞事要發生了——they trust the situation他們信任當下的處境，and that trust而這份信任is about to be used against them就快被拿來對付他們了。The key is關鍵在於that the reader or listener knows the danger讀者或聽者知道危險and the person does not而當事人不知道，so所以the word creates這個字會製造出a small feeling of dread or pity一種淡淡的恐懼或憐憫的感覺。

"He walked into the unsuspecting village." "The thief followed an unsuspecting tourist down the alley." It goes before a noun almost every time, and it collocates strongly with words for ordinary, innocent people: unsuspecting victim, unsuspecting public, unsuspecting customers, unsuspecting tourists, unsuspecting passers-by. You meet it constantly in crime reporting, in warnings about scams, and in storytelling.

"He walked into the unsuspecting village."他走進了那個毫無戒心的村莊。"The thief followed an unsuspecting tourist down the alley."小偷跟著一個毫無戒心的觀光客走進了巷子。It goes before a noun almost every time這個字幾乎每次都放在名詞前面，and it collocates strongly with words for ordinary, innocent people而且常常搭配這些指普通、無辜的人的字：unsuspecting victim沒有防備的受害者、unsuspecting public沒有戒心的大眾、unsuspecting customers沒有戒心的顧客、unsuspecting tourists沒有戒心的觀光客、unsuspecting passers-by沒有戒心的路人。You meet it constantly你會常常看到這個字in crime reporting在犯罪報導裡，in warnings about scams在詐騙警示裡，and in storytelling還有在說故事的時候。

There is also a lighter, joking use, for harmless surprises: "she crept up on her unsuspecting brother".

Notice how it differs from its neighbours: "unsuspicious" means not causing suspicion, or not feeling suspicion, and is much weaker; "innocent" is about having done nothing wrong; "naive" blames the person for being foolish. "Unsuspecting" does not blame — it simply says the person did not see it coming, and often invites sympathy for them.

Notice how it differs from its neighbours注意它跟這些鄰近字的不同："unsuspicious" means not causing suspicion, or not feeling suspicion意思是不會引起懷疑、或自己不覺得懷疑，and is much weaker而且語氣弱很多；"innocent" is about having done nothing wrong講的是沒有做錯事；"naive" blames the person for being foolish則是在怪這個人太天真、太傻。"Unsuspecting" does not blame不帶責怪的意思——it simply says它只是說the person did not see it coming這個人沒有預料到，and often invites sympathy for them而且常常讓人對他們產生同情。
