Hayley教口語，“半信半疑”用英語怎么說？

UK (US take sth with a grain of salt)

to not completely believe something that you are told, because you think it is unlikely to be true

對(duì)…半信半疑，對(duì)…有所懷疑

關(guān)于這個(gè)短語的起源有一說從老普林尼的《自然歷史》得知，當(dāng)時(shí)發(fā)現(xiàn)一種毒藥的解藥配方其中一種成分是一粒鹽。就有了吃點(diǎn)鹽就能解毒的說法，因此，當(dāng)談及毒藥的威脅時(shí)，人們就開始半信半疑。

You have to take everything she says with a pinch of salt, because she tends to exaggerate.

你不能完全相信她的話，她總是喜歡夸大其詞。
