161. It probably has something to do with the fact that nicotine (尼古丁) is an appetite suppressant and appears to up your metabolic rate.
譯文
這可能與尼古丁有關(guān),它能抑制你的食欲,并且似乎可以加快你新陳代謝的速率。
點(diǎn)睛
本句的主干是It...has something to do with the fact that...。that引導(dǎo)的是fact的同位語(yǔ)從句,對(duì)其進(jìn)行解釋說明,該從句包含兩個(gè)并列的謂語(yǔ)is和appears。不定式短語(yǔ)to up your metabolic rate作appears的表語(yǔ)。
suppressant意為“抑制劑”。metabolic意為“新陳代謝的”。have sth. to do with意為“與……有關(guān)”。如:
Do you have something to do with this group? 你和這個(gè)集團(tuán)有關(guān)系嗎?
up在句中作動(dòng)詞,意為“提高,抬高”。如:
The price of meat has been upped. 肉類的價(jià)格已經(jīng)提高。
