The development of artificial intelligence（AI，人工智能）is a hot topic these days.AI makes it possible for machines to learn from experience and perform human-like tasks.But what is the future of AI？Will it be a good thing？We asked students what they thought.
| I think AI will be more useful in our future lives.It's now used in many fields like phones and medicine.No one really knows what will happen if machines become smarter than humans.However，I'm sure AI will help us solve problems. Tina |
| I am worried that people will create something that can be better than themselves.In the near future，AI will develop at a high speed.Humans may be replaced because AI robots will do lots of human jobs. Bill |
| I really think that AI will change the way we work，the way we live，and the way we think.Imagine if we could put a CPU（中央處理器） into our brains!Soon we'll be able to improve our math and memory.How exciting! Mary |
| Think of what's happening right now.Some robots are used to kill animals under human orders.So I think AI will be very dangerous for humans.We need to be careful about what we ask machines to do. John |

3．How Soccer Can Help Us Understand Physics Sports provide a great way to understand some concepts（概念） in physics.Physics，after all is the study of matter，motion（運動），force，and energy.And since sports liken soccer，swimming and cycling involve bodies moving through space，they can help us understand how the principles of physics work.
Imagine that you're looking at a soccer ball on a grassy field.If you do nothing to the ball，it will stay motionless on the grass.If you kick the ball，it will roll along the grass before coming to rest again.Pretty simple ，right？
For thousands of years，though，people thought that objects like this soccer ball come to rest because they have a natural tendency to stop.It took a famous physicist by the name of Sir Isaac Newton，who lived in the 1600s，to prove that this was not exactly correct.
Newton suggested that objects like the soccer ball have a natural tendency to keep moving.The only reason they stop，he believed，is because an unbalanced force acts on them.By an unbalanced force，Newton meant the force applied to the soccer ball by its environment.When kicked，the surface of the ball travels over the grass，creating friction（摩擦力）.The taller the grass，and the rougher the surface of the ball，the more friction is created.And the more friction that exists between the ball and the grass，the less it will travel after being kicked.
Now，imagine that there is no grass.Instead，the ball is resting on a frozen lake.When you kick the ball on the ice，the ball will go much farther than it would have on the grass.This is because ice provides a lot less friction than the grass.
Even so，ice does cause some friction.The ball's interaction with the frozen water crystals on the surface of the lake eventually causes it to come to rest again.But now imagine that instead of ice，the ball is in a place where there's no friction at all.The ball is floating in a vacuum.If you remove friction entirely，kicking the soccer ball would cause it to keep going and going at the same speed，until some force caused it to slow down and sjye.aip.To paraphrase Sir Isaac Newton，a soccer ball on the grass will stay where it is unless acted on by a force.Similarly，once you kick the ball，it will remain in motion unless acted on by force.This，in so many words，is known as Newton's First Law of Motion.
（1）According to the passage ，once an object like a soccer ball is in motion，it has a natural tendency to.
A．stop
B．slow down
C．keep moving
D．change direction
（2）What does the writer explain in the passage？
A．The idea of motion，using sports as examples.
B．The force of friction，using music as examples.

（3）What does the underlined word "tendency" mean？
A．A very small chance of something happening.
B．A fifty-fifty chance of something happening.
C．The way something normally behaves or acts.
D．The fear of doing something or acting in a certain way.
（4）The passage is mainly about.
A．the motion of objects
B．the life of Sir Isaac Newton
C．why we have to learn physics
D．why we kick the ball on a grassy land發(fā)布：2024/12/20 0:30:1組卷：32引用：2難度：0.3
