【Simin 的默写】

Seeing is believing. But seeing a huge rock half the size of earth smash into Jupiter in July 1996 was incredible. Can you imagine what would happened if the Earth collided with a huge space rock? It would be disastrous. In fact, it is thought that a meteor killed the dinosaurs millions of years ago.

A rock like the one that hit the Jupiter could split the Earth in two. Do nothing about it is like waiting the end of earth. So scientists plan to start a project to identify all space rocks that could hit Earth.
