46、 to make a profit by the charges(n.) for admission.2.名词转化为动词很多表示物件、身体部位、某类人的名词可以用作动词来表示动作,某些抽象名词也可以作动词。如:Did you book a seat on the plane?Please hand me the dictionary.She nursed her husband back to health.We lunched together yesterday.3.形容词转化为动词有少数形容词可以转化为动词。如:We will try our best to better our living conditions.She cleans her room every day.4.副词转化为动词有少数形容词可以转化为动词。如:Murder will out.(谚语)恶事终将败露。The army downed a plane.- 10 - 版权所有高考资源网
