      All right, Squeaks. Are you ready?

      好了,吱吱。準備好了嗎?

      Oh, hey, there. You caught us at a really great time.

      哦,嘿。你找我們的時間正好。

      It's almost spring here at the Fort, which means we're going to start getting a lot of different kinds of weather.

      福特堡快迎來春天了,這意味著我們將開始迎來各種不同的天氣。

      Rain, thunder, late snow, warm days, cold days, even fog.

      雨、雷、晚雪、暖天、冷天,甚至還有霧。

      So to brush up on all the different types of weather, there are and how they happen.

      因此,為了溫習一下所有不同類型的天氣,有幾種天氣,以及它們是如何發生的。

      We're going to play a game.

      我們要玩一個游戲。

      I'm going to give Squeaks some clues and he's going to try and tell me what sort of weather I'm talking about.

      我會給吱吱一些線索,他會試著告訴我我說的是什么樣的天氣。

      And if he gets most of them right, he'll win an amazing prize.

      如果他答對了其中的大部分,他將贏得一個驚天大獎。

      You can play along too.

      你也可以一起玩。

      Alright, you ready?

      好了,準備好了嗎?

      Hello, there, everyone, and welcome to the game of weather wisdom What's the Weather.

      大家好,歡迎收看天氣智慧游戲--是什么天氣。

      I'm your host, Mr. Brown and our contestant today is Squeaks, the robot lab rat.

      我是你們的主持人,布朗先生,我們今天的參賽者是機器鼠吱吱。

      Squeaks is seven years old. He enjoys science, loves food and it says here that you're scared of spiders.

      吱吱已經7歲了。他喜歡科學,喜歡食物,害怕蜘蛛。

      Is, is that true?

      是真的嗎?

      Fascinating.

      令人著迷。

      Well, there won't be any spiders in today's game so you can rest easy what there will be is lots and lots of weather.

      好的,今天的比賽不會有蜘蛛,所以你可以放心,因為會有好多天氣。

      Let's get to our first question.

      讓我們開始我們的第一個問題。

      This type of weather happens mostly in the winter.

      這種天氣主要發生在冬天。

      It happens when tiny particles of water freeze high up in the clouds stick together and fall down to earth as little crystals.

      當凍結在云層高處的微小水粒粘在一起,以微小晶體的形式落到地面上時,就會發生這種情況。

      And it's really fun to sled in this weather too.

      而且在這樣的天氣里拉雪橇也很有趣。

      Name that weather, squeaks.

      說出那個天氣的名字,吱吱。

      That's right, Squeaks.

      沒錯,吱吱。

      The answer is snow.

      答案是雪。

      Now here's Jesse to tell us more.

      下面是杰西為我們帶來的更多信息。

      Who's up for a word game?

      誰想玩這個文字游戲?

      When I say science, what picture comes into your mind.

      當我說科學時,你腦海中浮現出什么樣的畫面。

      Is it stuff like test tubes and telescopes?

      是試管和望遠鏡之類的東西嗎?

      Maybe it's computers or microscopes or living things like flowers or frogs.

      也許是電腦或顯微鏡,也可能是鮮花或青蛙之類的生物。

      But did you think of anything that looks like art?

      但你有沒有想到任何看起來像藝術品的東西?

      A lot of science is really beautiful.

      很多科學真的很美。

      And there might be no better way to study the beauty of nature than by looking at snowflakes.

      也許沒有比看雪花更好的方式來研究大自然的美了。

      Have you ever taken a close look at snowflakes in the winter when they land on your coat or mitten just before they melt?

      你有沒有仔細觀察過冬天的雪花,當它們落在你的外套或手套上,就在它們融化之前?

      Each snowflake is a six-pointed work of art as cool and as individual as the ones you've probably made with paper and scissors.

      每一片雪花都是一件六角的藝術品,就像你可能用紙和剪刀做的一樣酷,也一樣有個性。

      But how does nature make snowflakes?

      但是大自然是如何形成雪花的呢?

      First thing to know is the little six-pointed pieces of ice that you and I call snowflakes are really made up of snow crystals.

      首先要知道的是,你我稱之為雪花的小六角形冰塊實際上是由雪晶組成的。

      Scientists use the word snowflake to describe the fluffy white things that fall from the sky, which are actually bunches of snow crystals all stuck together.

      科學家們用雪花這個詞來描述從天空落下的蓬松的白色物體,它們實際上是粘在一起的一串串雪晶。

      And the journey of a snow crystal begins in a cloud.

      雪晶的旅程從云中開始。

      Up there water in the form of gas called water vapor.

      在那里,水以氣體的形式存在,被稱為水蒸氣。

      Freezes around a piece of dust or pollen that's just floating around in the cloud.

      凍結在一塊漂浮在云層中的塵埃周圍。

      This forms what's called a seed crystal and seed crystals can become snow crystals if conditions inside the cloud are just right.

      這就形成了所謂的籽晶,如果云層內部的條件恰到好處,籽晶可以變成雪晶。

      As the sea crystal bumps around inside of the cloud lots of particles that make up water.

      當海洋水晶在云層內部顛簸時,大量的顆粒組成了水。

      Stick to it, the particles that make up water have a very specific shape.

      堅持,構成水的顆粒有一個非常特殊的形狀。

      They kind of look like the letter V and when enough of these particles stick together they form shapes that have six sides called hexagons and that's your most basic kind of snow crystal.

      它們看起來有點像字母V,當足夠多的粒子粘在一起時,它們形成了有六個邊的形狀,稱為六邊形,這是最基本的雪晶類型。

      But if there's enough water around then, more water particles will attach at the little points of that six-sided crystal, each becoming an arm or a branch.

      但如果周圍有足夠的水,更多的水顆粒就會附著在這個六邊形晶體的小點上,每個顆粒都會變成一只手臂或一根樹枝。

      From there all kinds of different things can happen even though all snowflakes have six sides.

      從那里可以發生各種不同的事情,即使所有的雪花都有六個面。

      They can end up looking totally different from one another.

      他們最終可能會看起來完全不同。

      In fact, scientists have names for more than 30 different shapes of snow crystals some are big and flat and are called plates.

      事實上,科學家們有30多種不同形狀的雪晶的名字,其中一些又大又平,被稱為星盤狀雪花。

      Others look long and narrow called needles.

      其他看起來又長又窄的,被稱為雪針。

      Still others are tall and wide like columns.

      還有一些像柱子一樣又高又寬。

      And then, there's probably the most famous shape called dendrites.

      然后,可能有一種最出名的形狀叫做樹枝晶。

      They look kind of like stars that have sprouted, tree branches.

      它們看起來有點像已經發芽的星星,樹枝。

      The shape that each snow crystal takes depends on what the conditions were like.

      每個雪晶的形狀取決于當時的天氣條件。

      As it formed in the cloud, things like temperature and how much water is in the air can make a big difference if you're a snowflake.

      因為它是在云中形成的,如果是一片雪花,溫度和空氣中水分的多少等因素會產生很大的不同。

      So for example, colder temperatures often make flakes with more pointy and fancy arms.

      例如,較低的溫度通常會使雪花有更尖更花哨的手臂。

      While snow crystals that are made in warmer temperatures and air with less water in it tend to be smaller and simpler.

      而在溫度較高、空氣中水分較少的環境中形成的雪晶往往更小、更簡單。

      Now you might have heard that no two snowflakes are alike.

      現在你可能聽說過,沒有兩片雪花是一樣的。

      A lot of them do look really similar to each other.

      很多雪花看起來真的很相似。

      But scientists think that it would be really hard for any two to end up being exactly the same.

      但科學家們認為,任何兩片雪花最終都很難完全相同。

      That's because the conditions in the clouds are always changing.

      這是因為云中的條件總是在變化。

      So the flakes that they make are always changing too.

      因此,它們制造的薄片也總是在變化。

      Once a snowflake takes shape, its journey has only just begun.

      一旦雪花成形,它的旅程才剛剛開始。

      After bouncing around in the cloud for a while it falls to the ground and as it falls it keeps changing depending on the temperature.

      在云里彈了一段時間后,它落到地面上,隨著它下落,它會隨著溫度的變化而不斷變化。

      The amount of water in the air and other things like wind that it passes through.

      空氣中的水和其他東西,如風,傳過了多少風。

      Since each flake takes a different path all the way to the ground , each one ends up being slightly different.

      由于每一片雪花都會沿著不同的路徑到達地面,所以每一片雪花最終都會略有不同。

      And that's why scientists say that no two snowflakes are exactly the same.

      這就是為什么科學家們說沒有兩片雪花是完全相同的。

      But they're all really interesting and beautiful.

      但它們都很有趣,也很漂亮。

      So now you know how snow crystals are made by nature, miniature. Works of art, no scissors required.

      所以現在你知道雪晶是如何由自然、微型自然創造的。藝術品,不需要修剪。
