解析：
本题考查一般现在时的基础语法规则：当句子主语是第三人称单数时，对应的谓语动词要使用第三人称单数形式，结合方框给出的单词匹配句意即可：
1. 原句主语是复数The girls，谓语用动词原形feel，改写后主语The girl是第三人称单数，feel的第三人称单数形式是feels。
2. 原句主语是复数Bobby and Sam，谓语用动词原形fly，改写后主语Willy是第三人称单数，fly的第三人称单数形式是flies。
3. 原句主语是复数The students，谓语用动词原形study，改写后主语My brother是第三人称单数，study的第三人称单数形式是studies。
4. 原句主语是复数They，谓语分别用动词原形give和try，改写后主语He是第三人称单数，give的第三人称单数形式是gives，try的第三人称单数形式是tries。
5. 原句主语是第一人称I，否定助动词用don't，改写后主语The boy是第三人称单数，对应的否定助动词用doesn't。
1. 读一读，用括号中所给词汇的适当形式填空。
Li Ming is a student. He
(not like) sport. He cannot run fast. He can not play basketball well. He
(feel) bad. But he
(not give up). He
(ask) his teacher for help and
(do) exercise every day. He
(try) hard to run fast. He also
(learn) basketball skills (技巧) from other students. He is good at sport now. He
(feel) happy.
答案：doesn't like; feels; doesn't give up; asks; does; tries; learns; feels
解析：
本题考查一般现在时的用法，全篇主语均为第三人称单数He：1. 实义动词的否定形式需要借助助动词doesn't，后面接动词原形；2. 肯定句中的实义动词要变为第三人称单数形式，常规变化为直接加s，以辅音字母+y结尾的动词要先将y变为i，再加es。
