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的同位語從句,對其進行解釋說明,該從句包含兩個并列的謂語is和appears。不定式短語to up your metabolic rate作appears的表語。
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? 你和這個集團有關(guān)系嗎?
up在句中作動詞,意為“提高,抬高”。如:
The price of meat has been upped. 肉類的價格已經(jīng)提高。
