The Laboratory

Reading Practice · Track 2-1 · 朗读顺序:先慢读两遍,再尝试不看文字跟读

Mia's father had a laboratory, but she had no idea what was in it. Her dad always closed and locked the door when he went in. She knew that he used it to do projects for work. He never told Mia what these projects were.

📌 米娅的爸爸有一间实验室,但她完全不知道里面有什么。爸爸每次进去都会关好并锁上门。她知道爸爸在里面做工作项目,但从没告诉过她是什么。

One night, Mia approached the door to the laboratory. She stopped and thought, “I wonder what crazy experiment he is doing now.” Suddenly, she heard a loud noise. It sounded like an evil laugh. The noise scared her, so she walked quickly back to her room.

📌 一天晚上,米娅走到实验室门口,停下来想:"不知道他又在做什么疯狂实验。"突然她听到一声巨响,听起来像邪恶的笑声。她被吓坏了,赶紧快步走回房间。

The next night, her friend Liz came to her house. When Liz arrived, Mia told her about the night before. “Oh, it was terrible,” she said. “Why don't we see what is in there?” Liz asked. “It will be a fun adventure!”

📌 第二天晚上,朋友莉兹来家里。莉兹一到,米娅就说起昨晚的事。"哦,太可怕了。"她说。"我们为什么不进去看看?"莉兹问。"那一定是个有趣的冒险!"

Mia felt nervous about going into her father's laboratory, but she agreed. As always, the door was locked. They waited until Mia's father left the laboratory to eat dinner. “He didn't lock the door!” Liz said. “Let's go.”

📌 米娅对进爸爸的实验室感到紧张,但还是答应了。和往常一样,门锁着。她们一直等到爸爸离开实验室去吃晚饭。"他没锁门!"莉兹说。"我们走!"

The laboratory was dark. The girls walked down the stairs carefully. Mia smelled strange chemicals. What terrible thing was her father creating?

📌 实验室里很黑。两个女孩小心翼翼地走下楼梯。米娅闻到奇怪化学品的气味。爸爸到底在做什么可怕的东西?

Suddenly, they heard an evil laugh. It was even worse than the one Mia heard the night before. What if a monster was going to kill them? Mia had to do something. She shouted for help.

📌 突然她们又听到邪恶的笑声,比昨晚那声更可怕。万一有怪物要杀死她们怎么办?米娅必须做点什么。她大声呼救。

Mia's father ran into the room and turned on the lights. “Oh, no,” he said. “You must have learned my secret.”

📌 米娅的爸爸冲进房间,打开灯。"哦,不。"他说。"你们一定是发现了我的秘密。"

“Your monster tried to kill us,” Mia said.

📌 "你的怪物想杀死我们。"米娅说。

“Monster?” he asked. “You mean this?” He had a pretty doll in his hands. The doll laughed. The laugh didn't sound so evil anymore. “I made this for your birthday. I wanted to give it to you then, but you can have it now. I hope you like it!”

📌 "怪物?"他问。"你们说这个?"他手里拿着一个漂亮的娃娃。娃娃笑了,那笑声听起来不再那么邪恶了。"这是我给你做的生日礼物。我本想那时再给你,不过现在给你也行。希望你喜欢!"
朗读建议:这篇以一般过去时叙述的小故事,第一遍先听全文(1×),圈出所有动词过去式;第二遍分段 0.75× 慢读跟读。读到 "It sounded like an evil laugh." 时压低声音制造恐怖气氛,读到 "I made this for your birthday." 时语气转暖——体会故事从紧张到温馨的反转。

文章结构分析 How the Text Is OrganizedA Story with a Twist

这是一篇「起因 — 发展 — 高潮 — 结局」的记叙文,结尾还有一个反转。把握故事线,就能看懂作者是怎么一步步制造悬念、再揭晓真相的:

START · 起因

好奇心

爸爸锁着实验室从不让她看,米娅充满好奇——里面到底在做什么?

→
RISING · 发展

夜探实验室

朋友莉兹提议一起去冒险,两人趁爸爸吃晚饭,偷偷溜进黑暗的实验室。

→
CLIMAX · 高潮

惊吓呼救

"邪恶笑声"再次响起,比上次更可怕——万一有怪物要杀她们?米娅大声呼救。

→
END · 结局

反转揭晓

灯亮了:所谓"怪物"其实是爸爸做的会笑的生日娃娃。秘密揭晓,温馨收尾。

小发现:记叙文常用过去时讲述故事,用 was doing 表示"正在…",用 What if… 制造紧张感。作者故意把娃娃的笑声说成 an evil laugh(邪恶的笑声)来误导读者——这种「误导—反转」的手法(twist)让结局更有惊喜。
爸爸手中的漂亮娃娃——故事的结局
故事结尾:爸爸手里的"怪物",其实是一个会笑的漂亮娃娃(AI 生成配图)

语法聚焦 Grammar FocusFrom the Text

记叙文讲"过去的事",动词时态和从句是重点。下面 6 个语法点全部来自课文《The Laboratory》:

① 一般过去时 · 故事叙述

用动词过去式讲过去的事

记叙文讲已经发生的事,动词要用过去式。规则动词加 -ed;不规则动词要单独记:go→went、come→came、hear→heard、leave→left、run→ran、make→made、tell→told、say→said。

课文:She knew that he used it to do projects.
Suddenly, she heard a loud noise.
He made this for your birthday.
小练习:Yesterday I ____ (see) a big dog in the park. → saw
② 过去进行时 was / were + v-ing

表示"过去正在做"

was/were + 动词-ing 表示过去某个时刻正在进行的动作。课文里 "what crazy experiment he is doing now" 是站在过去的时间点上想"他(那时)正在做什么";"was going to kill them" 是 be going to 的过去式,表示"将要/打算"。

课文:I wonder what crazy experiment he is doing now.
What if a monster was going to kill them?
小练习:At 8 o'clock last night, I ____ (watch) TV. → was watching
③ 不定式 to do

表目的 / 作动词宾语

to + 动词原形在课文里有两种用法:表目的(used it to do projects 用来做项目、left to eat dinner 去吃晚饭)和作动词宾语(had to do something 不得不做、tried to kill us 试图杀死、wanted to give it to you 想给你)。

课文:She knew that he used it to do projects for work.
Mia had to do something.
I wanted to give it to you then.
小练习:My brother tried ____ (catch) the ball. → to catch
④ 动名词 v-ing · 介词后

介词 + v-ing

介词后面跟动名词(v-ing),表示"做某事"。课文里:nervous about going into her father's laboratory——about 是介词,后面用 going。

课文:Mia felt nervous about going into her father's laboratory.
小练习:She is good at ____ (swim). → swimming
⑤ 情态动词与助动词

must have / can / didn't / What if

must have + 过去分词表示对过去事情的肯定推测("一定已经…");can 表示"可以";didn't 构成否定;What if… 表示"万一…怎么办",用来制造紧张感。

课文:You must have learned my secret.
You can have it now.
He didn't lock the door!
What if a monster was going to kill them?
小练习:He looks tired. He ____ (must have) stayed up late. → must have
⑥ 从句 · 宾语从句 & 状语从句

that / what / when / until

that 引导宾语从句(She knew that…),口语中常省略;what 引导名词性从句(no idea what was in it、what these projects were);when 引导时间状语从句(when he went in、When Liz arrived);until 引导时间状语从句(waited until…)。

课文:She knew that he used it to do projects.
He never told Mia what these projects were.
They waited until Mia's father left.
小练习:I don't know ____ he said. → what

仿写全文 A Birthday Surprise · 生日惊喜

套用课文《The Laboratory》的句式与"悬念—反转"结构,把"实验室"换成"后院小房间"、"娃娃"换成"机器人",就是一个全新的小故事:

开篇 · 好奇

My mother had a small room in the backyard, but I had no idea what was in it. She always closed and locked the door when she went in. I knew that she used it to do projects for our family. She never told me what these projects were.

夜探 · 发现

One night, I approached the door to the small room. I stopped and thought, "I wonder what crazy project she is doing now." Suddenly, I heard a loud noise. It sounded like a strange laugh. The noise scared me, so I walked quickly back to my room.

夜探 · 好友

The next night, my friend Ben came to my house. When Ben arrived, I told him about the night before. "Oh, it was terrible," I said. "Why don't we see what is in there?" Ben asked. "It will be a fun adventure!"

潜入 · 黑暗

I felt nervous about going into my mother's small room, but I agreed. As always, the door was locked. We waited until my mother left the room to cook dinner. "She didn't lock the door!" Ben said. "Let's go." The room was dark. We walked down the stairs carefully. I smelled strange paint.

高潮 · 惊吓

Suddenly, we heard a strange laugh. It was even worse than the one I heard the night before. What if a monster was going to jump at us? I had to do something. I shouted for help.

结局 · 反转

My mother ran into the room and turned on the lights. "Oh, no," she said. "You must have learned my secret." "Your monster tried to scare us," I said. "Monster?" she asked. "You mean this?" She had a beautiful robot in her hands. The robot laughed. The laugh didn't sound so strange anymore. "I made this for your birthday. I wanted to give it to you then, but you can have it now. I hope you like it!"
