课件网) 人教新目标版 七年级下学期 21世纪英文报 初一 728期 作者：陈嘉华 listening Earth has been spinning faster for years. 地球自转速度变快，你的一天变短了？ When we’re busy, we often say “There’s not enough time in the day!” In fact, our days really are getting shorter – just a (very little) bit less than 24 hours.? This is because our planet is spinning (旋转) faster. It’s been doing this for a while – about 50 years. Earth had its shortest day on July 19, 2020, when the day was 1.46 milliseconds (毫秒) shorter than 24 hours. The year 2020 had 28 of Earth’s shortest days since 1960. This year will have even more short days. Scientists say that Earth is spinning faster because of the movement of its core (地核), as well as weather and ocean patterns (变化规律). According to the journal (刊物) Science Advances, global warming (全球变暖) might also play a part. When glaciers melt (冰川融化), it changes the distribution of mass (质量分布) on Earth and makes the planet spin faster. ? BY MIKE FUKSMAN,?21ST CENTURY TEENS STAFF What should we?do about this? Our clocks tell us the time according to a strict 24-hour cycle (循环). If Earth keeps spinning faster, we might need to take one second away from the clock. This will match our time with Earth’s rotation (旋转).?
