网友回答
(答案→)1.advantage→advantages
解析：
1.advantage→advantages advantage为可数名词，前面有there are，表明此处应用复数形式。
2.was→is 全文时态为一般现在时，应该将过去时态的谓语动词was改为一般现在时is。
3.正确。
4.working→work 由句子结构可知，该行中working应该作谓语动词使用，不能用working。
5.allow→allowing 该句主语为Earning their own money。该结构作主语，谓语用单数。
6.去掉if 该行中的as应该引导方式状语从句，所以去掉if。
7.would后加not 有上下文的逻辑意义可知该句应该表示否定含义。
8.by→with by表示抽象的含义，而此处表示具体含义。
9.去掉to 该句中may为情态动词，其后用动词原形作谓语。
10.our→their 由于该句中的主语为Some students为复数第三人称形式，所以把our改为their。
