We've all faced it at one time or another：after laundry，a messy pile of clean clothes are waiting hours to be put away.There are plenty of machines that can wash and dry clothes.So why isn't there a way to similarly automate the terrible folding process？
   Researchers have looked into it over the years and as it turns out，robots just don't do well in folding clothes.As is reported，machines need clear rules in order to function，and it's hard for them to figure out what exactly is going on in those messy piles—say，where the sweater stops and where the towel begins.In sum，most robots have not generally been equipped for the task.But an international group of researchers say their new method could change that，or at least speed up the process.
   Researchers are calling the new method Speed Folding.It's a "reliable and efficient biannual system"—meaning it involves two hands—that's able to smooth and fold clothes in record speed for robots.Speed Folding can fold 30 to 40 pieces of clothing per hour，compared to previous models that averaged 3 to 6 pieces in that same time length，according to researchers.
   Speed Folding takes a different approach.Its novel network studied 4，300 human and machine-assisted actions in order to learn how to smooth and fold clothes from a random pattern.That process can involve a number of defined movements including dragging，moving and"pick-and-place".
   While researchers describe Speed Foldingas a significant improvement，it's not likely to hit the market anytime soon.For one，researchers tracked down a robot similar to the one they used and found that it sold for ＄58，000.For another，researchers say there's more they want to explore，including methods with which the robot can learn to work on a novel piece of clothing when given a few demonstrations.But there's always hope that folding in the future will get even neater.

（1）Why are robots poor at folding clothes？
C
C

A．It is difficult for them to obey clear human orders.
B．They are lacking in enough folding demonstrations.
C．They have trouble handling the random patterns of clothes.
D．It is difficult for them to remember the folding movements.
（2）What do we know about Speed Folding？
A
A

A．It can perform more delicate actions.
B．It can help with all sorts of housework.
C．It can record the working speed accurately.
D．It can fold 3 to 6 pieces per hour on average.
（3）What does the author think of Speed Folding？
C
C

A．It is highly profitable.
B．It is no better than the old.
C．It has a promising future.
D．It will go out of style quickly
（4）What can be a suitable title for the text？
B
B

A．Robots Become More Intelligent
B．The Fastest Ever Folding Robot is Here
C．Robots Release People from Housework
D．The Research on the Folding Robot is On

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

2．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．
