一、连一连：把左边的句子和右边最合适的句子连起来。
1. The boy is young. a. It’s fun, though.
2. The game is short. b. He can cook by himself, though.
3. I was a little nervous. c. I succeeded in the end, though.

1-b，2-a，3-c

本题考查的是连词“though”的用法，它通常用于表达“尽管、虽然”的意思，引导让步状语从句。我们需要根据每个句子的语境，找到与“though”引导的从句相匹配的主句。
1. “The boy is young.”描述的是男孩的年龄小，而“though”后面通常接的是与前面信息相反或有所保留的内容。选项b“He can cook by himself, though.”表示“尽管他年纪小，但他还是会自己做饭。”，这与原句信息相匹配。
2. “The game is short.”描述的是游戏的时间短，而“though”后面应该接的是关于游戏时间短但仍有某种积极方面的内容。选项a“It’s fun, though.”表示“尽管游戏时间短，但它很有趣。”，这与原句信息相匹配。
3. “I was a little nervous.”描述的是我之前的紧张情绪，而“though”后面应该接的是关于我紧张但最终还是取得了某种成果的内容。选项c“I succeeded in the end, though.”表示“尽管我有点紧张，但我最终还是成功了。”，这与原句信息相匹配。
