如痴用英语怎么说呢

"如痴" (rú chī) in Chinese means to be completely absorbed or absorbed to the point of obsession.
One possible way to say this in English is "to be completely engrossed" or "to be completely absorbed." For example:
She was completely engrossed in the book and didn't notice the time passing. (她完全沉浸在书中，没有注意到时间的流逝。)
He was so completely absorbed in his work that he didn't even hear the doorbell. (他完全沉浸在工作中，甚至没有听到门铃声。)
The phrase "如痴" (rú chī) is derived from the Chinese idiom "如痴如醉" (rú chī rú zuì), which means "to be completely absorbed or absorbed to the point of obsession, as if drunk or in a trance." This idiom is often used to describe someone who is deeply immersed in an activity or pursuit.
Here are some examples of how the idiom "如痴如醉" (rú chī rú zuì) can be used in Chinese:
他如痴如醉地看着那幅画，一句话也不说。(Tā rú chī rú zuì de kàn zhe nà fú huà, yī jù huà yě bù shuō.) He stared at the painting as if in a trance, not saying a word.
她如痴如醉地玩手机，什么也不听。(Tā rú chī rú zuì de wán shǒu jī, shén me yě bù tīng.) She played with her phone as if in a trance, not listening to anything.
