Answer 1

1. C。题意为：答应参加这次聚会的人占大多数。be in the majority是固定短语，意为“占大多数”。
2. A。题意为：部门里面除了我和汤姆之外，没人指导经理要辞职。作主语的名词或代词后有as well as,with, along with, together with, but等引出的成分时，谓语动词的单复数仍由其前的主语决定。所以本题中谓语动词的形式要与No one保持一致，用单数形式。
3. D。题意为：中国加入世贸之后，每个人学点英语还是很有必要的。have a knowledge of是固定短语，意为“掌握……”。
4. A。题意为：我们必须尽我们所能来帮助那些有困难的人。do... to help“做……来帮助……”不定式to help作目的状语。
