✦ AI INTRODUCTION 学习难度

Speed tells us how fast something moves. A racing car has high speed, while a walking turtle has low speed. We can also use “speed up” when something begins to move faster.

  1. Cars should not drive at high speed in the city.
  2. The runner increased her speed near the finish line.

What is the fastest thing you know? Use “speed” in your answer.
