(1) Bill was standing at the side of the car， talking to two men who was
helping him to repair it. (was 改为were，因先行词 two men 是复数，所以修饰该先行词的定语从句的谓语动词也应用复数)
(全国卷)
(2)Playing football not only makes us grow up tall and strong but also give
us a sense of fair play and team spirit.(give 改为 gives，它与makes
为平行结构，构成并列谓语动词)
