He hopes to be a doctor in the future. In his free time, he also likes making video games. At school, he joins a coding (编程) club. It is called ACCESS. ACCESS teaches students to do computer programming (编程). A computer program helps computers do many things. The program is written in code. It uses words, numbers and anything else. The code gives the computer instructions (指令) to follow. That is how people make apps and games. These people are called coders. Hemant is learning a lot in the club. He learns how to make his own games. He just finished one last week. In the game, a player moves a yellow ball away from black balls. “It is kind of like Pac-Man,” Hemant said excitedly. In the club, some students know the latest technology. Others do not even have a computer at home because their parents don’t have enough money to buy it. Some coders are just starting to learn. Others already know how to code something. “That’s not a big problem. Everyone learns something new in our club,” their teacher said. Jey Veerasamy is a great coding teacher. He helps run the coding club program. “There is one important thing about coding something. You cannot be afraid to make mistakes. It is the only way to learn,” he says. Dr. Veerasamy wants students to try new things. If they don’t work, kids can try other new things. The club will teach students some important skills and they will help them achieve their dreams. It’s worth trying again and again. 14. Why does the writer mention Hemant Pacha in Paragraph 1? A. To show a good job. B. To show a famous person. C. To tell us a new school. D.

B 【解析】 【导语】本文以少年Hemant为例介绍ACCESS编程社团，讲述社团里学生基础各不相同，并借老师的话告诉我们学编程不要害怕犯错，该社团能传授实用技能、助力学生实现梦想。 【14题详解】 第一段“Hemant Pacha is 13 years old… At school, he joins a coding (编程) club. It is called ACCESS.”通过讲述Hemant加入名为ACCESS的俱乐部，引出了本文主要介绍的对象——编程俱乐部，因此作者提到他是为了引出ACCESS这一主题。 【15题详解】 第三段“In the game, a player moves a yellow ball away from black balls. ‘It is kind of like Pac-Man,’ Hemant said excitedly.”可知，Hemant在谈论他制作的游戏，并将其与Pac-Man类比，由此推断Pac-Man也是一款视频游戏。 【16题详解】 最后一段“The club will teach students some important skills and they will help them achieve their dreams. It’s worth trying again and again.”提到俱乐部教授学生重要技能并帮助他们实现梦想，鼓励反复尝试，这表明编程俱乐部对学生来说是有帮助且重要的。 【17题详解】 最后一段“The club will teach students some important skills and they will help them achieve their dreams.”说明俱乐部教技能，这些技能帮助学生实现梦想，因此they指代的是复数名词skills。 Ⅳ．阅读还原五选四（4分） A: Hi, Li Fen. ____18____ B: I took part in the Ancient Chinese Poem Reading Competition last Sunday in the Chinese Poem Club.

They keep practicing every day. Many of them play it well. Some of them get into great middle or high schools. Some of them make it into soccer clubs and become professional players.
