原声例句
Crash Course 天文篇 The Earth has umbral and penumbral shadows, too. 地球也有本影和半影。 Crash Course 天文篇 The umbral shadow of the Moon is pretty small where it hits the Earth, so a total eclipse is a local event. 月亮的本影笼罩地球的部分很小,所以日全食是地区性的现象。 Crash Course 天文篇 A solar eclipse is localized to one spot on the Earth, or really a swath along the ground as the Moon's umbral shadow sweeps across the Earth's surface. 日食是区域性现象,仅限于地球上某一特定地点,或者说是月亮本影扫过地球表面的那片区域。 Crash Course 天文篇 Outside of this deep umbral shadow is a wider conical region where, if you're in it, the Sun is only partially blocked; you can still see some of the Sun past the Moon. 在这个本影范围之外,有一个更宽的锥形区域,如果你身处其中,太阳只会被部分被遮挡;你仍然可以看到一部分没被月球遮挡的太阳。 国家地理科普(视频版) The first is a total lunar eclipse, when the Sun Moon and Earth are in perfect alignment and the moon falls within the Earth's umbral shadow, total lunar eclipses are the most striking of the three types. 首先是月全食,当太阳和月亮与地球完美对齐,月亮落在地球阴影内时,月全食是三种类型中最引人注目。 |
