281．As Wilson Guarin watched the helicopter flying above，he wondered if the men being lifted into the sky felt the risk had been worth it.
Moments earlier，Guarin and his children had hiked to Hermit Falls in Angeles National Forest，one of the most popular waterfalls in the Los Angeles area.Soon after they arrived，they saw a man injure his shoulder when he jumped into the rock pool at the base of Hermit Falls.Less than a minute later，another man jumped and appeared to break both his legs.Guarin said the cliff jumpers' purposes were obvious.They wanted to get a video of themselves and post it to social media.
A thirst among hikers，often inexperienced and under-prepared，to collect "likes" and shares on Instagram and other social media sites has led to a sharp increase in rescue missions by first responders.
The Los Angeles County Sheriff's Department's Search and Rescue teams conducted 681 missions in 2017，the largest number in five years.It's a 38% increase from the 491 rescues they did in 2013.
The teams' leaders say the single largest factor for that increase is people posting videos of extreme activities online.Then，without any thought about the difficulty，others try to recreate their own 15-second version of glory.
On Instagram，posts from visitors making adventures in waterfalls and swimming holes in Angeles National Forest and other recreation areas show hikers changed into models，striking seemingly the same poses in the same places.
We shouldn't prevent people from enjoying the outdoors.But many accidents are avoidable and happen either when people go off trail or ignore official warnings about an area being closed and visit anyway.
Guarin still thinks about the two men he watched in helicopter rides sent to a hospital. "You get concerned about what people are willing to do-to not have fun.It's risking everything for no reason.

Or do newborns simply prefer more to fewer？The same experiment，but with three spots shown before two，shows the same return of interest when the number of spots changes．Perhaps it is just the newness？When slightly older babies were shown cards with pictures of objects（a comb，a key，an orange and so on），changing the number of objects had an effect separate from changing the objects themselves．Could it be the pattern that two things make，as opposed to three？No again．Babies paid more attention to squares moving randomly on a screen when their number changed from two to three，or three to two．The effect even crosses between senses．Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two；likewise（同樣地） when the researchers started with drumbeats and moved to spots．

the beach，Natalie can see the ocean and hear the wave from her house. "It's the ocean that makes Rockaway so special，" she says.
October 29，that ocean turned fierce（激烈的）.That night，Hurricane Sandy attacked the East Coast，
and Rockaway was hit especially hard.Fortunately，Natalie's family ran away to Brooklyn shortly before the city's bridge closed.
When they returned to Rockaway the next day，they found their neighborhood in ruins.Many of
Natalie's friends had lost their homes and were living far away.All around her，people were suffering，especially the old.Natalie's school was so damaged that she had to go to a school in Brooklyn.
In the following few days，the men and women helping Rockaway recover encouraged Natalie.
Volunteers came with lots of clothing and toys.Neighbors offered their spare time to help others rebuild.Teenagers climbed stairs to deliver water and food to people trapped in powerless high buildings.
"My mom tells me that I can't control what happens to me，" Natalie says. "but I can always choose
how I deal with it."
Natalie's choice was to help.
She created a website page matching survivors in need with people who wanted to help.In the coming months，her website page helped lots of kids：Christopher，who received a new basketball；Charlie，who got a new keyboard.Natalie also worked with other organizations to bring much-need supplies to Rockaway.Her efforts made her a famous person.
Today，the scars（創(chuàng)痕） of destruction（破壞）are still seen in Rockaway，but hope is in the air.
The streets are clear，and many homes have been rebuilt. "I can't imagine living anywhere but Rockaway，" Natalie says."My neighborhood will be back，even stronger than before."

（cruel） of his words cut her like a knife．發(fā)布：2025/1/1 17:0:1組卷：8引用：5難度：0.7288．Human beings are extremely diverse in many ways.People differ in opinions，races，nationalities，lifestyles and so on.Yet we are all human species，we feel pain and joy despite the differences.Today，it is impossible for any group of people to live without interacting with others outside their group.（1）
Diversity creates richness in opinion.Some problems can't be solved by a homogeneous（同種類的）group of people. （2）A diverse group will offer fresh ideas to solve the problems.Diverse groups have been found to be creative and thus producing better solutions to problems.
Diversity makes us compassionate about others.When we interact and try to understand others，we won't judge them.This instead makes us compassionate about others.（3）Compassion allows us to realize that all human beings are the same.
Diversity is a growing trend.Today，there is no country in the world that has only natives living there.（4）In the process，people of different cultural backgrounds often find themselves going to the same schools，working in the same office and so much more.As citizens of this word，we are therefore left with no choice other than embrace our diversity.
（5）Through diversity，entrepreneurs（企業(yè)家）have been able to reach new markets.Today，we have multinationals setting up offices in different parts of the world of which it would not be possible without embracing diversity.This future creates employment opportunities for people in those parts of the world.
A.They are in search of good lifestyles.
B.Diversity opens up new market chances.
C.Diversity requires us to respect each other.
D.We are then able to love and help one another.
E.Cultural diversity，therefore，is very important today.
F.The challenge requires people from different backgrounds to work together.

發(fā)布：2025/1/1 17:0:1組卷：57引用：2難度：0.6290．The Mozart in the Machine Sometime in the coming decades，an external system that collects and analyzes biometric data （生物特征數(shù)據(jù)） will probably be able to understand what's going on in my body and in my brain much better than me.What will it do to art？Will art remain humanity's last line of defense against the rise of the all-knowing algorithms （算法）？
In the modern world art is usually associated with human emotions.We tend to think that artists are controlling internal psychological forces，and that the whole purpose of art is to connect us with our emotions or to inspire in us some new feeling.Consequently，when we come to evaluate art，we tend to judge it by its emotional impact and to believe that beauty is in the eye of the beholder.
In 1952，the composer John Cage composed a musical piece 4'33" This piece consists of 4 minutes and 33 seconds during which no instrument plays anything.The piece encourages the audience to observe their inner experiences in order to examine what music is and what we expect of it.The message is that it is our own expectations and emotions that define music.
If art is defined by human emotions，what might happen once external algorithms are able to understand and manipulate human emotions better than Shakespeare，Picasso or Lennon？After all，emotions are not some mysterious forces —they are a biochemical process.Therefore，given enough biometric data and enough computing power，it might be possible to hack （入侵） love，hate，boredom and joy.
Of all forms of art，music is probably the most sensitive to Big Data analysis，because the inputs are the mathematical patterns of soundwaves，and the outputs are the electrochemical signals.Allow a learning machine to go over millions of musical experiences，and it will learn how particular inputs result in particular outputs.
Therefore，in the long run，algorithms may learn how to compose entire tunes，playing on human emotions as if they were a piano keyboard.Using your personal biometric data，the algorithms could even produce personalized melodies，which you alone in the entire world would appreciate.
Will this result in great art？That depends on the definition of art.If beauty is indeed in the ears of their listener，then biometric algorithms stand a chance of producing the best art in history.If art is about something deeper than human emotions，biometric algorithms might not make very good artists.But nor would most humans.In order to enter the art market，algorithms won't have to begin by straight away beating Beethoven.It is enough if they outperform Justin Bieber.
