Rocket Hits Asteroid

Hi students! Today I want to talk about asteroids. An asteroid is a big rock in space. 我們今天來聊聊小行星！ Scientists worry that an asteroid might hit Earth in the future. What would happen if an asteroid did hit Earth? If it were big enough, it would cause lots of trouble! 學家擔心小行星未來會撞到地球。如果小行星太大，我們就有麻煩了！ Remember the dinosaurs? Scientists think an asteroid hit the earth about 66 million years ago and killed them. 科學家認為有一顆小行星在六千六百萬年前撞到地球，把恐龍殺死了。 Right now, scientists don't think any asteroids will hit our planet soon. But what about in the future? 現在沒有小行星會撞到地球，但是以後呢？ I don't want to scare you guys, but an asteroid might hit us one day. But, here's the good news! NASA sent a rocket to hit an asteroid in space as a test. 不用擔心，美國太空總署 NASA 測試了用火箭撞擊小行星。 It took 10 months for the rocket to hit the asteroid. The rocket blew up, but the asteroid didn't. The purpose of the test was to hit the asteroid to change its direction. 花了 10 個月的時間火箭才擊中小行星，而且爆炸了，但小行星沒有。測試的目的是要撞擊小行星，改變他的方向。 NASA scientists wanted to see if they could hit the asteroid. That way, if an asteroid is coming right at Earth, we can hit it with a rocket. The rocket can make the asteroid miss Earth. Whew! Now, I feel safer! ________________________________ Vocabulary 這個實驗很像電影吧？故意用火箭去碰撞小行星，好讓它不要跟地球相撞。 1. hit 打到，撞擊 One of those stars may hit us someday. 那些星星有一顆可能會撞到我們。 And you're worried? 你很擔心嗎？ Not really.
