Satellites are already in use for so many purposes today---from weather forecasting to communications，GPS，and more.Since the late 1970s，satellites have also been used to monitor changes in the Arctic sea ice.Data suggests that sea ice is thinning over time due to climate change.Over the last forty years，the extent of Arctic ice cover has been declining at a rate of 13%per decade.However，existing ways of measurement do not provide a clear and continuous picture of the state of sea ice.
   This September，scientists developed a new method that combines computer modeling and satellite data to predict ice thickness all year round.Over the years，scientists have proposed several methods to measure ice thickness.These include flying planes over the Arctic Ocean or collecting field measurements.
   Neither of these methods provides a full picture of Arctic melt，making year-long data collection difficult.Continuous data across the entire region from satellites is a great way for scientists to understand how climate change is playing out in the Arctic.
   These satellites use special radar or laser-based altimeter instruments.Sea ice thickness is then calculated as the difference between the height of the ice and the top of the water（ice level---sea level）.This method works well during the winter months---September to May.
   Unfortunately，satellite-based sea ice thickness measurements are inaccurate during the summer months：the time of the year with the greatest melting.This melting creates a pool of liquid water on the surface.As a result，the simple calculation（ice level---sea level）does not work as radar systems are unable to differentiate between ocean water and ice，thus rendering measurements inaccurate.
   New research led by Jack Landy，a scientist，seeks to tackle this age-old issue.The team used machine learning and deep learning methods to distinguish between seawater and ice.
   The researchers built a model of the radar system's predicted data and cross-referenced these values to those collected by a satellite.This model allows the researchers to obtain accurate，year-round Arctic sea ice thickness data.

（1）Why are satellite-based sea ice thickness measurements not accurate？
A
A

A．The ice melts in summer months.
B．The radar system doesn't work in winter.
C．The liquid water turns ice in cold days.
D．The ocean water comes onto the ice surface.
（2）What does the age-old issue refer to？
B
B

A．The changeable climate change.
B．The incorrect ice measurements.
C．The constantly flowing ocean water.
D．The great amount of melting ice.
（3）How do the researchers study Arctic sea ice changes in the new research？
D
D

A．By using satellites to collect data.
B．By collecting field measurements.
C．By flying planes over the Arctic Ocean.
D．By using machine learning and deep learning methods.
（4）What is the best title for the passage？
C
C

A．A new device to measure ocean water
B．A new stage for the application of satellites
C．A new way to monitor Arctic sea ice changes
D．A new finding about the rising sea level

1．At the beginning of Grade Two，I joined the cross-country running team in our school.
   When I came to the first practice，I was filled with optimism.But as the distance we ran in each practice gradually increased from three to four，to six miles，I realized with surprise that no matter how hard I tried，I wasn't able to run as fast as others.In fact，I was one of the slowest on the team.
   What was the point of putting myself through so much pain？After the first few weeks，I wanted to quit.
   Then we had our first cross-country meet.
   When we started the race，I felt the great pressure of expectations sink onto my shoulders.And after a while I stopped running and struggled to walk up the hill.But then I heard my coaches shouting my name from the top of the hill.I felt confused and embarrassed；why were they cheering for me？I was running terribly!As I tried my best to finish the race，I realized that my coaches didn't care how fast I ran.Neither did my teammates.During the rest of the season，they were always on the sidelines of every race，cheering for me just as loudly as they'd cheered for the front runner.
   From then on，I began to put my effort into supporting my teammates instead of focusing on my own performance.In that way，I celebrated my teammates' victories as if they were my own；I felt their pain and exhaustion as if they were my own.
   Cross-country running made me realize I don't need to be the best to be successful in life.It taught me to value my relationships with people more than my relationship with my ego.It taught me to cheer for others even if I don't know their names.

（1）Why did the author want to give up after the first few weeks？

A．He had much pain in his knees.
B．He didn't perform well in long-distance running.
C．He couldn't get along well with others
D．He showed no interest in running.
（2）Which of the following can best describe the coaches？

A．Strict and hard-hearted.
B．Brave and adventurous.
C．Considerate and supportive.
D．Optimistic and humorous.
（3）After his first cross-country race，the author

.
A．lost himself in victories
B．put more effort into his study
C．received more support from his coaches
D．started caring about his teammates
（4）What did the author realize from his experience？

A．The importance of team spirit
B．The value of competition
C．The secret of winning a race
D．The benefits of doing sports

3．We all know that regular exercise is good for us．In recent years we've been told to aim to walk 10，000 steps a day to remain healthy，although other advice to do three 10-minute walks a day is thought to be even more effective．But the latest piece of research might put a spring in your step if you're someone who walks at a fast pace．That's because，according to scientists，the speed at which people walk in their 40s is a sign of how much their brains，as well as their bodies，are ageing．
   The BBC's Philippa Roxby writes that tests on 1，000 people from New Zealand born in the 1970s found that slower walkers tended to show signs of "accelerated ageing"．Their lungs，teeth and immune systems were in worse shape than those who walked faster．And to add insult to injury，the study found not only did slower walkers' bodies age more quickly，their faces looked older and they had smaller brains．Professor Terrie，lead author of the study，told the BBC： "It found that a slow walk is a problem sign decades before old age．"
   This might be seen as a wake-up call for people with a slower pace who might feel it's time to work out and get fitter．But it might be too late；researchers say they were able to predict the walking speed of 45-year-olds using the results of intelligence，language and motor skills tests from when they were aged three．They also suggest that even in early life，there are signs showing which people will go on to have a healthier life．
   So，what's the point of knowing that a slower walking pace might mean a smaller brain？Well，researchers say measuring walking speed at a younger age，and understanding what this might mean，could be a way of testing treatments to slow human ageing．This might help us make lifestyle changes while we're still young and healthy．Any steps we can take to prolong a good mental and physical state is a no brainer!

（1）What is the text mainly about？

A．Walking and health．
B．Slow walking and ageing．
C．The way of slowing ageing．
D．The standard walking pace．
（2）What does the latest research show？

A．Walking 10，000 steps a day helps keep fit．
B．A slower walker is healthier than a faster walker．
C．Slower walkers are easy to have slower brains．
D．Ageing signs of slow walkers arise earlier than fast walkers．
（3）What does the underlined words "wake-up call" refer to in paragraph 3？

A．Challenge．
B．Potential．
C．Reminder．
D．Solution．
（4）What can we infer from the last paragraph？

A．Testing walking speed before old age makes sense．
B．It's important to keep fit both physically and mentally．
C．Walking pace is connected with health and ageing．
D．Walking speed at a young age determines one's longevity．
