Astronauts on board the International Space Station（ISS）once made history by taking bites of red romaine lettuce（長葉萵苣）.They became the first humans to eat food that was grown in space.The lettuce was planted on the ISS in a small greenhouse called "Veggie"，which uses LED lights to help plants grow in space.
First，the astronauts cleaned the lettuce with special sanitizing wipes（消毒紙巾）and then ate it with some salad dressing.
"It was one small bite for man，one giant leap（ 飛躍）for ...our journey to Mars，" one astronaut，Scott Kelly，later posted on social media.
Space vegetables are a part of the NASA experiment called "Veg-01"-a study on how plants grow without the effects of Earth's gravity（重力）.It will allow astronauts to grow and eat their own food during long space explorations.
"If we're ever going to go to Mars someday，we're going to need a spacecraft that is much more self-sustainable （自給自足的） in is food supply，" said Kelly.
Growing fresh plants on a spacecraft may also provide oxygen and help keep astronauts alive，NASA said.
Veg-01 started in May 2014.The first batch （一批） of vegetables took 33 days to grow in space before they were taken back to Earth for a safety check.After making sure they were safe to eat，astronauts planted a second batch on July 8.They let the plant grow for another 33 days and were then able to eat it.Astronauts usually only get vegetables when a supply ship comes to the ISS.Now with vegetables grown in space，they can eat them whenever they want.

2．The city of Changchun ，Jilin province gut something special，on Sept 13-its first 3 D-painted bus that gives a feel of diving into the sea and coming into close contact with it.
The idea for the bus ，which belongs to the Beidu Co，came from Wang Zhi，an employee who took part in its creation competition not long ago .and who comments（評(píng)論）"I've seen 3 D buses in other cities and suggested that we have one here. "
The bus，which is also decorated by sea dolls and handicrafts like"dolphins" ，and"starfish" ，runs from Yanminghu villa to the lakeside street and stops at Beilhuancheng Rd.They choose "Sea Tour"as the theme because the color blue and cute creatures might make passengers more relaxed .especially in traffic jams ，says Wang.

Some passengers ask the driver for the bus timetable ，saying they want to bring their families and friends to enjoy the fun ，while the driver ，Gu Zhenning ，says，"I'm even happier than the passengers working in such a comfortable environment.
The company says it will promote the use of these buses to make the ride more comfortable and enjoyable.

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(yùn)動(dòng)），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.
C．The sport of soccer，using examples of teams and players.
D．The importance of understanding the concepts in physics.
（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
