小西妈双语工程2105期171Sam打卡Day258
看到上面这张图片，作为家长，第一时间会想到什么？跳伞？滑翔？学开飞机？运送救援物资？当你把这个图片给5岁以下的孩子，特别是男孩看的时候，他们大概率会说出下面几句话中的一句或几句：
1、我是乐迪，每时每刻，准时送达！
2、是时候呼叫超级飞侠来帮忙啦！
3、是时候呼叫超级飞侠团队了！
4、团队合体，装备启动！
5、是时候呼叫超级装备啦！
6、是时候呼叫超级救援了
7、包裹就让你送吧！
孩子爱看动画片，这个无可厚非，就像Mac&Mighty妈妈（乐乐妈）一样，老大爱玩手游，小学低年级就开始玩吃鸡。但是后面硬生生的被乐乐妈从吃鸡游戏，到百科，军事，一战，二战，枪，再到世界史，英雄人物传记，丘吉尔，岳飞，王昌龄，边塞诗……
从乐迪到普通直升机
到军用直升机，喷气式，螺旋式
那么，就一起继续往下走吧！
SUPER WINGS 超级飞侠
See, Daddy bought you some Super Wings toys. Let’s change Jet into a robot with his legs and arms out. First, we push his front wheel in. Then, we pull his legs out，and push them down. Now we can push up his landing gear wheels, and put the flap at the back down. Now we turn his feet around，and press down the tabs小片片，so he can stand up. Finally, we need to pull out his arms，and then pull out the hands. Now you can twist the arms however you like.
1. What is a helicopter?
A helicopter is a kind of aircraft. Unlike an airplane, a helicopter can fly straight up and down, sideways, or backward. It can also spin around or hover motionless in the air. Helicopters can fly lower than airplanes can, too.
Like an airplane, a helicopter flies using wings. A helicopter’s wings are thin, narrow blades that rotate, or spin around. The blades on top of a helicopter, along with the parts that connect them, are called the main rotor. The main rotor is connected to an engine. The engine sends power to the main rotor to spin the blades. Most helicopters have just one main rotor, but some have two or more.
As the blades spin, air pushes against them. A helicopter Pilot has controls that change the position of the blades. This affects how the air hits them. The pilot also controls how much power the engine sends to the rotor. Using these controls together, the pilot can move the helicopter up, down, forward, backward, or sideways.
A helicopter also has a small set of blades in the back. This is called the tail rotor. To turn the helicopter, the pilot pushes pedals that move the tail rotor. The tail rotor also keeps the helicopter from spinning around.
2. make a helicopter
Cut out the helicopter
Cut along the dashed lines of the template. If you’re using plain paper, make a sketch of the helicopter solid and dashed lines as a guide.
Fold along the solid lines
The propeller blades, A and B, should be folded in opposite directions along the solid lines. The X and Y panels fold toward the center, and Z is folded upward to give the body of the helicopter rigidity and lower its center of gravity for more stable flight.
Do a test flight
Stand up and hold the helicopter by its body. Raise it as high in the air as you can. Now, drop it. What do you observe? Which way do the blades turn? Drop the helicopter from a higher spot. (Climb a few stairs or stand on a step stool.)
How does the performance change?
Compare
Grab an unfolded piece of paper the same size as the one used to make the helicopter. Drop it at the same time as the helicopter. Which falls faster? Wad up the piece of paper into a ball. Drop this paper ball at the same time as the helicopter. Which falls faster? Can you guess why? Hint: It has something to do with air resistance.
Helicopters are useful because they can fly almost anywhere. They are used to rescue people from disasters such as fires, floods, and earthquakes. Helicopters can quickly carry injured people to a hospital. They can even land on the roofs of some hospitals and other buildings. Armies use helicopters to attack the enemy and to carry soldiers and equipment. Police use helicopters to look for criminals. Farmers use them to spread seeds and fertilizers on their fields.
(1)fire-fight
See how I go!
I fill my massive water tank from a lake or a river using my snorkel[ˈsnɔːrkl]. It’s a like a big straw that can suck up 2000 gallons of water in just 45 seconds.
Today, I have some friends to help me. They carry giant “Bambi” buckets that they fill from a lake, too.
Water tanks, snorkel, rotor blades, Bambi bucket
我是消防直升机
看看我是怎么工作的！
我用潜水通气管从湖或河里放满了巨大的水箱。这就像一根大吸管，可以在45秒内吸掉2000加仑的水。
今天，我有一些朋友来帮助我。他们还携带着巨大的“小鹿斑比”水桶，把它们也从湖里灌满。
水箱，潜水通气管，螺旋桨，小鹿斑比水桶
Then we fly away and hover over the center of the fire.
Cockpit
Our pilots take aim and……
whoosh! [wʊʃ]
Like a waterfall, our tanks and buckets empty onto the flames.
然后我们飞走，悬停在火的中心。
座舱
我们的飞行员瞄准并……嗖！
就像瀑布一样，我们的水箱和水桶向火焰倾倒。
(2)rescue people
Here I am using my winch cable to rescue a stranded mountain climber.
在这里，我正在使用绞车电缆来救助一名滞留的登山者。
Oh, naughty boy , I don’t know why you like climbing trees.
How are we going to rescue him?
Chop the tree down.
No. I’ ll ring the fire engine.
Fire service!
What happened?
A naughty boy is stuck on the tree.
We’re on our way.
Fire engines use ladders to rescue pets from trees.
Naughty boy is climbing higher in the tree. Fire fighter is climbing into the tree.
They all get stuck.
No! We’ll have to call the highest rescue service in the land.
OK, I’m on my way.
Thank you, Pilot, for saving them.
No problem. Just in my job. Goodbye.
(3)armed helicopter
An armed helicopter is a helicopter equipped with weapons.[1] Most commonly, it is used for attacking targets on the ground. Such a helicopter could be either purposely designed for a ground-attack mission—in which case it would be more specifically categorized as an attack helicopter—or may have been previously designed for other uses, such as utility, cargo, reconnaissance, etc., with the weapons mounts being modifications, rather than part of the design of the helicopter. The purpose of the modification to an armed helicopter configuration can be field expediency during combat, the lack of military funding to develop or purchase attack helicopters, or the need to maintain the helicopter for missions that do not require the weapons.
(4)look for criminals
Police use helicopters to look for criminals.
(5)helicopter on the farm
Farmers use them to spread seeds and fertilizers on their fields.
The helicopter is designed for treating agricultural crops with pesticides, applying liquid or dry mineral fertilizers to the soil.
