In this video we're going to talk about fractions

and I want you to understand the concept of a fraction using visual illustrations.

So let's say if we have a circle.

Let me draw a better looking circle.

And let's split the circle into two equal parts.

Now I'm going to shade only one portion of those two parts.

So what fraction of the circle is shaded?

So there's two parts of the circle and only one of those two parts is shaded.

So we could say that one half of the circle is shaded.

Now let me give you another example.

Let's say if I have a circle and I split it into four equal parts.

And I'm going to shade this part of the circle.

So what fraction of the circle is shaded?

So there's four equal parts of the circle, and three of those four parts were shaded.

So three-fourths of the circle is shaded.

Now let me give you another illustration.

So let's say we have a circle again.

And this time, I'm going to divide the circle into eight equal parts.

So what fraction of the circle is shaded?

So we know that there's eight parts, the circle was divided into eight equal parts, and only three of those eight parts were shaded.

So three-eighths of the circle is shaded.

And so hopefully these visual illustrations help you to understand a concept of a fraction, which is basically a portion out of a whole.

Now here's another example for you.

So let's say we have a rectangle.

And it's broken up into seven congruent parts.

Now granted, my drawing is not perfect, but we'll make it work.

And let's say three of those parts is shaded.

What fraction of the rectangle is shaded and what fraction is not shaded?

So there's seven equal parts, and three of those seven parts are shaded

so we could say three-sevenths of the rectangle is shaded now

out of this total seven parts four of those seven parts is not shaded

so four-sevenths of the rectangle remains unshaded or not shaded Now,

let's look at another example.

So let's say we have a square.

And we're going to break up the square into a total of eight parts.

What fraction of the square is not shaded?

And what fraction is shaded?

So out of the eight parts, five of those parts is shaded.

So we can say that five eighths of the rectangle, or rather, of the square is shaded.

Now what fraction is not shaded?

out of the total eight parts, three parts is not shaded.

So hopefully these visual illustrations help you to solidify the concept of a fraction.

So here's a practice problem for you.

Draw a circle and shade only two-fifths of the circle.

So feel free to pause the video.

So here's a circle, and we'll need to break it up into five equal parts.

So that's going to be one, we'll say two, three, four, and five.

So once you split it into five parts, all you need to do is shade two of those five parts.

And so in this case, two-fifths of the circle has been shaded.

And so that's basically it for this video.

So now you understand fractions with circles and squares and rectangles.

So that's basically it for this video.

and if you need help with adding or subtracting fractions

or even multiplying

and dividing fractions I'm going to post a few links in the description section of this video

so you can take a look at that when you get a chance.

Thanks for watching.

FOR YOU

看YouTube學英語：這個“分數”影片為何適合口語練習？

這個講解分數的影片是非常好的口語學習素材！它的語言簡單易懂，句子結構清晰，還搭配了視覺畫面，能幫你邊理解邊模仿。影片裡的表達都是日常教學中常用的，比如“split into... equal parts”“shade... portion”，既實用又容易上手。對於剛開始練習英語發音和語調的同學來說，這樣的內容不會有太大壓力，很適合用來培養語感。

拆解自然表達，掌握地道口語

我們來看看影片裡的幾個自然句子：

“So what fraction of the circle is shaded?” 這句話用了“so”來引起思考，口語中很常用，讓對話更親切。“is shaded”的被動語態在這裡很自然，符合描述畫面的語境。
“Now let me give you another example.” “now”用來轉換話題，過渡流暢。“give you another example”是典型的教學用語，簡單直接，容易模仿。
“So three-fourths of the circle is shaded.” 分數的表達“three-fourths”清晰準確，“of the circle”明確說明物件，句子結構完整但不復雜，適合影子跟讀練習。

這些句子之所以聽起來自然，是因為它們符合英語的口語習慣，沒有複雜的語法，卻能準確傳達資訊。

影子跟讀練習法：跟影片學英語的正確步驟

想要用好這個影片練習口語，試試“英語影子跟讀”（shadow speech）吧！步驟很簡單：

先完整看一遍影片，理解內容，注意說話人的語調和節奏。
逐句播放，每句話聽完後暫停，立刻跟讀，儘量模仿發音、語調和語速。這就是“repeat-and-record”的過程，你可以用手機錄下自己的跟讀，對比原音找差距。
重點練習分數表達和提問句式，比如“what fraction of... is shaded?”，反覆跟讀直到熟練。
最後，不看字幕，跟著影片全程跟讀，就像和說話人“同步說話”一樣。這個方法不僅能提升口語流暢度，對雅思口語練習也很有幫助哦！

堅持每天練習5-10分鐘，你會發現自己的發音和語感都在進步。記住，犯錯沒關係，關鍵是敢說、多練！

影片中的語法

說話人最常用的結構，並附上影片中的原話：

結構	影片中的用法
被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的	is shaded · were shaded · was divided
“going to” 表將來 be going to + 動詞 — 計劃或明顯即將發生的事	we're going to talk · I'm going to shade · I'm going to divide
“will” 表將來 will + 動詞 — 決定、承諾或預測	we'll make · we'll need · we'll say

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。
