How come we have to go in the house when it's lightning outside?
10
Who do we ask for help when we have questions?
11
Da -da -da -da!
12
Maggie the Magnifying Glass!
13
I'm Maggie, Maggie, I help to make things clear.
14
Just look through my looking glass and answers will appear.
15
I'm Maggie, Maggie, come and let's explore.
16
And we'll discover lots of things you never knew before.
17
I'm Maggie!
18
How come we have to go in the house when it's lightning outside?
19
Anytime you hear thunder or see lightning, you need to look for a safe place to be.
20
Lightning and thunderstorms are a type of dangerous and powerful weather.
21
Powerful weather storms take place all over the world every day.
22
Would you like to find out more about storms?
23
If so, we can go on a little adventure together!
24
Would you like to learn about powerful weather, too?
25
You would?
26
Me, too!
27
Yippee -skippee!
28
Let's go!
29
Don't forget your journal!
30
Oh, yeah!
31
Got it!
32
My terrific scientific journal!
33
Bring yours along, too!
34
What are storms?
35
Storms are a combination of weather that together make a powerful weather pattern.
36
Storms can happen in warm weather and cold weather too.
37
Some types of storms are blizzards, thunderstorms, tornadoes, and hurricanes.
38
storms are a part of weather
39
and all weather starts with sun weather gets its energy from the sun the sun heats up the earth's surface
40
that warms up the air in the atmosphere warm air weighs less than cool air
41
so the warm air rises or moves up When the warm air moves up,
42
cool air, which weighs more than the warm air, sinks or moves down and replaces the warm air.
43
Now, as the warm air moves up, it cools off, then begins to sink.
44
This movement of air, warm air rising, cool air sinking, is an important part of making weather.
45
All storms are created by two opposing weather patterns that collide.
46
When they collide, it creates energy.
47
The more energy, the more powerful the storm can be.
48
I'm going to write that down in my journal.
49
Storms are a severe form of weather and happen every day all over the world.
50
Weather gets energy from the sun.
51
Got it!
52
What are thunderstorms?
53
Let's talk about thunderstorms.
54
Thunderstorms are a type of storm that has rain, thunder, lightning, and sometimes hail.
55
Thunderstorms happen in places that are warm and humid.
56
Like most weather, thunderstorms get their energy from the sun.
57
On a hot summer day, the sun heats up the Earth's land and water.
58
The Earth's surface heats up the air.
59
The warm air rises, colder air sinks.
60
The sun heats a body of water like an ocean.
61
The water evaporates or turns into steam or vapor and then travels up into the sky.
62
Then the water vapors become cooler and come together, collecting in clouds.
63
Rain clouds are caused by the build -up of water droplets or solid ice ice crystals.
64
The clouds get heavy and water falls back to the earth as precipitation,
65
rain, hail, sleet, or snow.
66
Okay, but what causes the lightning and what causes the thunder?
67
I was wondering the same thing.
68
Excellent question.
69
What causes lightning and thunder?
70
Here's what happens.
71
Well, inside the cloud, strong air currents cause the air molecules to rub up against each other.
72
This causes static electricity.
73
Have you ever rubbed your feet on the floor wearing socks?
74
Touched a doorknob and filled a shock?
75
That's static electricity!
76
And that's sort of what happens in a thunderstorm.
77
Sometimes lightning can happen inside the cloud when an arc of electricity is created because of the difference of electrical charges.
78
Lightning that happens inside clouds is called sheet lightning.
79
Lightning can also happen because of the earth.
80
The earth is positively charged.
81
This can attract lightning.
82
In this situation, an arc of electricity can strike, and the Earth answers with a return stroke.
83
When lightning occurs, it can heat up the air to thousands of degrees.
84
This causes the air to expand rapidly.
85
This causes a huge shockwave we call thunder.
86
When you see lightning and hear thunder, you should try to get indoors.
87
You can always find safety in a car.
88
Stay away from trees, towers, water, or any metal objects.
89
I'm going to write that down in my journal.
90
So, thunderstorms start with clouds.
91
Static electricity causes lightning.
92
Thunder happens when the lightning heats up the surrounding air.
93
Got it!
94
What are tornadoes?
95
Sometimes large -scale thunderstorms called supercells can create a tornado.
96
Thunderstorms form when warm, humid air rises upward.
97
This is called an updraft.
98
As the warm air rises, the cooler air begins to fall.
99
When it touches down, that's when a tornado is created.
100
Tornadoes come in different shapes and sizes.
101
Powerful tornadoes can demolish buildings and carry houses, cars and trucks in the air.
102
A tornado can destroy just about anything it touches.
103
I'm going to write that down in my journal.
104
Tornadoes are made from supercells or heavy thunderstorms.
105
Got it!
106
What are hurricanes?
107
Hurricanes are another kind of powerful storm.
108
It's a large, swirling storm.
109
that produces lots of rain and very high winds.
110
Hurricanes form over very warm parts of the ocean.
111
Here's what happens.
112
When high winds coming from opposite directions meet, they begin to rotate.
113
The high winds can cause very high waves and rough seas.
114
water vapor rises quickly
115
and adds more power to the storm the longer it moves
116
across the ocean the stronger the hurricane becomes in the center
117
of the hurricane is a low -pressure area called the eye of the hurricane when the storm reaches land,
118
the storm can begin to die down.
119
But it also pushes water to the shore.
120
This push of water is called a surge, or storm surge.
121
The surge can cause terrible floods.
122
Hurricanes produce lots of rain and high winds.
123
Hurricanes can cause a storm surge that can cause floods.
124
Got it.
125
What are blizzards?
126
Winter months can bring snowstorms, sleet, and freezing rain.
127
But the most powerful winter storm is called a blizzard.
128
Like all storms, blizzards can be very dangerous.
129
Blizzards combine heavy snowfall, severe cold, blowing snow and wind.
130
Blizzards make travel almost impossible.
131
Many times roads and airports are shut down because of a blizzard.
132
What makes a blizzard?
133
Excellent question!
134
Blizzards form when very cold air clashes with very warm moist air.
135
The warm air is lifted up over the cold air.
136
Where these two masses of air meet is called a front.
137
This interaction of cold and warm air colliding can cause precipitation.
138
Rain, hail, sleet, or snow For snow to fall,
139
it must be cold enough in the clouds and on the ground.
140
If the air is too warm, the snow will melt on its way down and change to rain, or freezing rain.
141
Freezing rain happens when the temperatures on the Earth's surface are below freezing.
142
The raindrops become supercooled.
143
The result is ice that can accumulate on trees, wires, cars, and more.
144
Freezing rain can cause travel problems on the roads and cause airports to be shut down.
145
Cold weather storms can be very dangerous.
146
Oh, I get it.
147
Blizzards are severe winter storms.
148
They form when warm and cold air collide.
149
Got it!
150
Thanks, Maggie!
151
You're very, very welcome.
152
Today I learned a lot about storms.
153
I hope you did, too.
154
These are the notes I took in my journal.
155
Storms are a powerful form of weather and happen every day all over the world.
156
Weather gets energy from the sun.
157
Thunderstorms happen in places that are warm and humid.
158
Tornadoes are made from supercells or heavy thunderstorms.
159
Hurricanes produce lots of rain and high winds.
160
Hurricanes can cause a storm surge that can cause floods.
161
Blizzards are severe winter storms.
162
Learning about storms is fun.
163
Let's go on another scientific adventure real soon.
164
Bye! So long!

什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
