dollars大于1 s ,即复数。 billion前面a或several ,如果你被卡住billion的s不重视。例子: He makes several billion dollars a year. (他一年赚数十亿美元。)例子: The company has a billion dollars to spend this week. (公司我需要花$ 10十亿的一周。)另外billion ,如果你提的话之前,确切数额billion不写复数。例子: She has two billion dollars. (她有20亿美元。)例如: Freddie makes eight billion dollars a year! (Freddy每年可赚80亿美元!)只有在没有特定金额的情况下,才能使用billion的复数形式。例如: Billions of people died from the disease. (数十亿人死于疾病。)
