hello judges teachers
2
and friends we are we are happy to be here at
3
today's stem festival our team members are my name is
4
and i'm the team leader as we all know fires can be dangerous sadly many people get hurt
5
because they don't know how to escape safely
6
so we want to have people learn what to do when there is a fire.
7
That's why we made a project called Smart Fire Alarm and Fire Escape Game.
8
Let's take a look.
9
Our project has two main parts, a smart fire alarm model and a fire escape game.
10
First, here is our model.
11
We used old cardboard boxes to make a small classroom.
12
Inside there is a control board.
13
It works like a brain of our system.
14
There are also sensors to detect fire and smoke.
15
How does it work?
16
When the system detects smoke or fire or when the temperature goes above 45 degrees Celsius,
17
the red light flashes and the alarm makes a loud sound.
18
This warns people about the danger so they can leave quickly.
19
Now let's look at our game.
20
We made this game ourselves using Scratch.
21
It helps students learn about fire safety while having fun.
22
In the game, you control a student.
23
When the fire alarm rings, you need to have the student get out safely.
24
First, you must pick up a wet towel to cover the character's nose and mouth.
25
Next, stay away from the flames and move towards the door with the exit sign
26
If you forget the towel or touch the flames,
27
the game shows a safety reminder You can try again and learn from your mistakes Through this game,
28
we want to have our friends remember what they have learned about fire safety Our project is useful in two ways First,
29
the alarm gives an early warning when there is a fire.
30
This gives people more time to get out safely.
31
Second, the game makes fire safety lessons fun and easy to remember.
32
We hope our project can help more students learn how to stay safe.
33
Thank you judges, teachers, and friends for listening.

Would you like to try our model and play our scratch game?
✨ 推荐视频
为何用这段视频练习口语?
这段视频展示了学生在STEM节上的项目展示,对话场景贴近真实生活,涵盖了介绍团队、解释项目创意、说明功能等实用表达。通过模仿这样的口语内容,不仅能提升在正式场合的表达能力,还能学习如何清晰传达复杂想法。对于想要通过看视频学英语的学习者来说,这种兼具实用性和趣味性的素材,能让口语练习更有针对性,同时还能积累科技与安全相关的词汇。
语境中的语法与表达
视频中有多个值得关注的表达和语法结构:
- “That's why we made...”:用于解释原因,逻辑清晰,适合在说明创意或行动目的时使用。
- “When... the red light flashes and the alarm makes a loud sound”:时间状语从句的应用,简洁描述事件触发机制,可用于讲解流程或原理。
- “We hope our project can help...”:表达期望的常用句式,语气诚恳,适用于展示成果后的总结。
这些结构在口语中高频出现,通过英语影子跟读(shadow speak)反复练习,能自然掌握其用法。
常见发音陷阱
视频中的部分词汇发音需要注意:
- “sensors”:结尾的“s”易被忽略,需发清辅音/s/,避免与“sensor”混淆。
- “Celsius”:重音在第一个音节,发音为/ˈsɛlsiəs/,不要误读为/selˈsiəs/。
- “reminder”:中间的“i”发短音/ɪ/,注意与“remember”的发音区别。
通过提高英语发音的专项练习,结合shadowspeaks技巧,逐句模仿视频中的语调与节奏,可有效改善发音准确性。
什么是跟读法?
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧,最初开发用于专业口译员的培训,并由多语言者Alexander Arguelles博士普及。这个方法简单而强大:您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同,跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性,语调,节奏,连读,听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
