程度副詞

No, Dr. Binocs, something just hid the sun.

Binocs 博士，現在不是晚上，而是有東西將太陽遮住了。

Oh, don't worry buddy, this is nothing but the eclipse!

As you can see, the Sun's got hidden and it's really dark out here.

如你所見，太陽被遮住了且外面一片漆黑。

你知道為什麼會有這種現象嗎？

Don't worry, it is nothing but the solar eclipse!

Come, let me tell you something about the solar eclipse today.

今天我會告訴你有關日蝕的知識。

A Solar Eclipse occurs when the Moon comes in between the Earth and the Sun causing a shadow of the Moon to fall on certain portions of the Earth.

當月亮在地球和太陽中間時，月亮的影子會落在地球的特定區域，這時就會發生日蝕。

From these locations, it appears as if the Sun has gone dark.

在這些區域，太陽看起來變暗了。

Since the Moon is very small in front of the Sun, it only blocks a part of it.

月亮比太陽小得多，所以只會遮住一部分的太陽。

Hence, a solar eclipse cannot be seen from every part of the Earth, but only from the locations where the shadow of the Moon falls.

因此，並不是世界各處都可以看見日蝕，而是只有月亮影子落在的區域才看得見。

So buddy, no reason to get scared now, is it?

所以夥伴，所以現在沒有理由感到害怕了對吧？

不，Binocs 博士，我現在一點都不害怕了！

The three major parts during a Solar Eclipse are, umbra, antumbra, and penumbra.

日蝕的三個主要部分為本影、偽本影和半影。

The Umbra is the portion of the Moon's shadow where the Moon completely covers the Sun.

本影是月亮影子的投射，將太陽完全覆蓋住。

This is when the total solar eclipse occurs, where you cannot see the Sun at all.

這時會發生的現象稱作「日全蝕」，也就是你完全看不見太陽。

Here the Moon is completely in front of the Sun, but doesn't cover the entire Sun.

此時月亮在太陽的正前方，但並未完全遮住太陽。

The outline of the Sun can be seen around the shadow of the Moon.

在月亮影子的周圍可以看見太陽的輪廓。

And that is when you see the Annular Solar Eclipse!

這時你看見的稱作「日環蝕」！

Penumbra is the area of the shadow where only a portion of the Moon is in front of the Sun.

當月亮只有一部份在太陽前方時，產生的影子區稱作「半影」。

This is when the Partial Solar Eclipse occurs, which let's you see only a part of the Sun.

這現象稱作「日偏蝕」，此時你只會看見一部分的太陽。

You could see how the Solar Eclipse works, in your homes!

你在家中就可以理解日蝕的運作方式。

Take these two balls, the bigger blue ball is the Earth and the smaller white ball will represent the Moon.

拿兩顆球，藍色大球代表地球，白色小球代表月亮。

Place them like this and light up the torch.

將兩顆球放成這樣，並打開手電筒。

There there, you just got a home-made Solar Eclipse!

如此一來，你會得到一個自製的日蝕！

One should never watch the Solar Eclipse with bare eyes because of the harmful UV rays.

大家不應該用肉眼觀看日蝕，因為紫外線對眼睛有害。

The longest a total Solar Eclipse can last is seven and a half minutes.

So now if day suddenly turns into night, you would know it is the Solar Eclipse.

所以如果白天突然變暗，你會知道這可能是日蝕。
