2025-2026学年外研版英语（2024）七年级上册 Unit 2 课文重点句子讲解 1. Right at this moment, the sound of Grandpa’s erhu cuts in. 就在这时，爷爷的二胡声插了进来。 句中 cut in 意为“插嘴，打断别人说话”。例如： She cut in when we were talking. 我们聊天时，她插了进来。 2. An idea suddenly hits me: “Why don’t we...” 我脑海中灵光一闪：“何不……” 句中 hit sb 的用法是俚语，常用于描述某人突然想到某个主意、发现某个事实或者突然理解了某个情况。其中 hit 指一种突然的认识或理解，像一个想法突然“击中”脑海。例如： The solution to the problem hit me in the middle of the night. 我在半夜突然想到了问题的解决办法。 The truth hit her hard and she could not help but cry. 事情的真相对她打击很大，她忍不住哭了起来。 3. I rush into his room... 我冲进他的房间…… rush into 意为“冲进，迅速进入”。例如： He rushed into the room to find his child. 他冲进房间去找他的孩子。 4. I nod to Grandpa and we fire up our instruments. 我朝爷爷点点头，然后我们开始演奏乐器。 fire up 在句中是比喻的用法，其中 fire 可理解为“点火，启动”。fire up 则理解为“开始或开始运作（机器、程序等）”。在句中比喻和爷爷开始演奏乐器，就像发动机开始运作起来一样。例如： Fire up the engine. We need to leave now. 启动引擎，我们现在该离开了。 5. Suddenly, a door appeared in the wall. 突然，墙上出现了一道门。 appear 意为“出现，呈现”，尤指突然或不可预见地出现。例如： The sun appeared from behind the clouds. 太阳从云后面出来了。 She appeared in the doorway. 她出现在门口。 A ship appeared on the horizon. 一艘船出现在了地平线上。 6. Emma shook her head and stopped writing. Emma 摇了摇头，停止了写作。 stop doing 意为“停止做”。需要注意 stop doing 是“停止正在进行的行为”，而 stop to do 则是指“停下正在做的事情去做另一件事”。也就是说，stop to do 中的行为是停止后要做的新行为，而不是被停止的行为。例如： I need to stop eating junk food. 我需要停止吃垃圾食品。 She stopped to tie her shoelaces. 她停下来系鞋带。 7.
