As Wilson Guarin watched the helicopter roaring 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 dislocate 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' intentions 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 significant 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 venturing to 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 discourage 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 hitching helicopter rides to a hospital. "You get concerned about what people are willing to do - to not have fun. It's risking everything for no reason. "
Well, there are the "likes".
1.What happened to the two jumpers'?
A.They both got badly injured.
B.They were trapped in a rock pool.
C.They were rescued by the Guarins.
D.They were caught in an air crash.
2.What is the main reason for the increase in the number of rescues?
A.Hikers are inexperienced and under-prepared.
B.Helicopters are readily available in more areas.
C.Travelers go off trail or ignore official warnings.
D.More people share their extreme activities online.
3.What do the figures imply in paragraph 4?
A.More social rescues are timely and effective.
B.More attention is paid from the social media.
C.More people raise the awareness of self-defense.
D.More public resources are obviously being occupied.
4.What does Guarin think of the jumpers' action?
A.It is not a wise thing to do.
B.It is their own version of glory
C.Watching it online is a lot of fun.
D.Getting "likes" makes it worthwhile.

Imagine yourself in a small airplane 3,300 meters above the ground. The engines roar in your ears as you move towards the open door. Then you' re outside, falling with the wind whipping past your ears. As the ground rushes up at you, you open your parachute. 1.. All in all, you were in free fall for only 30 seconds---the longest 30 seconds of your life.
2.. However, a growing number of adventurers are taking the risk. Obviously skydiving isn't something you can just try, like fishing or bowling. So, if you want to attempt the sport, you'll need to go to ground school.
3.. The course is taught by licensed skydiving instructors who have been jumping for years.
They'll teach you how to keep your body position stable. You'll also learn to be constantly aware of your altitude and, most importantly, when to open your parachute.
Once you' re through with ground school, it's time to get up in the air. 4.. Two instructors always jump with the person, ready to pull the student's parachute open if he or she freezes up.
5.. It certainly seems dangerous when you' re watching someone fall at 200 km/ hr. But, if you believe the statistics, skydiving is actually safer than driving, with one fatality (死亡) occurring in approximately 60, 000 jumps. Moreover, most enthusiasts agree all fear stops the second your feet leave the plane, and when you land, the only thought in your mind is, "Wow! I want to do that again!"
A. However, a new jumper never jumps alone.
B. It takes years to forget the taste of fear from skydiving.
C. No doubt, you're thinking skydiving is a dangerous sport.
D. It explodes over your head, pulling you back and upwards.
E. For most of us, skydiving is something we only see in the movies.
F. Ground school is where you learn to jump, without leaving the ground.
G. Skydiving is the sport of jumping out of an airplane and falling freely through the air.

On June 15th，2012，millions of people watched as 33yearold Nik Wallenda walked across one of the world's greatest waterfalls on a tightrope（钢丝）．What made the 25－minute walk that was televised live and watched by over 13 million people worldwide even more amazing，is that it was done over the Niagara Falls－An action that had never been attempted before．
Even though Nik was wearing a harness（保护带），a safety measure provided by ABC，the television network that broadcast the event，his action to keep his balance against the strong winds made for some heart－stopping（令人担忧的） moments for the audience．
Nik，however，never slowed down for even one moment．Wearing special shoes made by his mother，he remained totally focused on the job at hand．It was only when he got to the last stretch near Canada's Table Rock that he knelt down on one knee and finally broke into a smile．Waving and blowing kisses to the cheering audience，he knew he had accomplished a great task，which most people had thought impossible．
While he described the whole experience as peaceful and relaxing，Nik said his biggest challenges came from a totally unexpected source－his 40 pound balancing pole．The balancing pole was so heavy that he could hardly carry it on the tightrope．
One would think that now that Nik has realized his lifelong dream he would be ready to hang up his “balancing pole”．However，the adventurer who already has seven Guinness World Records under his belt，is just getting started－Next up? A 5，000－foot tightrope walk across the Grand Canyon．While the one across the Niagara Falls took years of planning because he had to convince the US and Canadian officials，this one should happen in the very near future．That's because，the Florida resident has already been granted（授予） a permit by the Canyon officials．
1.Why did so many people fix their attention on the event?
A．Because it was done by Nik Wallenda．
B．Because nobody had done it there before．
C．Because it was broadcast live by ABC．

The 1920s was a decade of wealth, decadence(堕落) and social changes. They were known as the Roaring Twenties, and the best place to experience this exciting time was New York City. But what was it really like?
Prohibition
In 1919, a new law in the US known as Prohibition made it illegal to buy and sell alcohol. But Prohibition didn’t stop people drinking; it just drove the sale of strong alcoholic drink underground. Bootleggers(走私贩) waited off the coast of New York after dark and brought illegal alcohol into the city.
Jazz
Jazz was the music of New York in the 1920s. In fact, the decade is called Jazz Age. The best place to listen to this new form of music was the Cotton Club in Harlem. All the great jazz musicians played at the Cotton Club, including Louis Armstrong, Dizzy Gillespie and Duke Ellington. Also, in 1942 George Gershwin composed the jazz—influenced Rhapsody in Blue. The piece has been called “a musical portrait of New York” and was used by Woody Allen in his film Manhattan.
Art Deco
Art Deco was the most popular style of the 1920s, with bright colors and geometric designs; it can be seen in the art, architecture and inside designs of the period. New York is full of Art Deco buildings, but the most famous ones are the Chrysler Building (built between 1928 and 1930) and the Empire State Building (built between 1930 and 1931).
The Great Depression
On 29th October, 1929, the Roaring Twenties came to a dramatic end. On that day (known as “Black Tuesday”), the US stock market crashed, causing the Great Depression. The economic downturn lasted ten years and affected most of the Western world. Unemployment in America reached 25% and the country didn’t recover until after World War II.
1.We know from the passage that in 1919 people ________ alcohol in the US.
A. began to buy and sell B. stopped producing
C. completely stopped trading D. secretly bought and sold
2.The 1920s is called _________.
A. Country Music Time B. Jazz Age
C. Folk Music Age D. Pop Age
3.We infer from the passage that the US _________ in the year 1930.
A. was in a bad economic state
B. was in good economic condition
C. developed at a rapid speed
D. had many dramatic plays

Running like the wind, roaring （咆哮） like thunder, tigers have long been feared and respected as a king of the animal world．But last week a report said that there are no more than 30 wild tigers left in south China．
This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund．
The South China tiger, also known as the Chinese tiger, is native to southern China．In the 1950's, there were over 4000 tigers found in mountain forests in the country．But due to the destruction of their natural habitat （栖息地） and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species．
Sixty-six of the big cats can be found in the cages of a dozen zoos around China．But they are nothing like their wild cousins．They have lost their natural skills such as hunting and killing．If they were set free they could not look after themselves．
"Breeding has damaged the quality of the species", said Pei Enle, deputy director of the Shanghai Zoo．
To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa．Four of them have already arrived．Progress has been made as two elder tigers have recovered some of their instincts（本能） and can hunt wild animals by themselves at the African base．
" South Africans are very experienced in reintroducing big animals to the wild．The country has very good natural conditions for the tigers to learn in", said Lu Jun, office director of the National Wildlife Research and Development Center．" We tried in Fujian Province, but it was not successful as there was not a complete eco-chain（生物链） and there was a lack of space．"
The tigers should return to China in 2007 when the reservations in Fujian are ready．
1.What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?
A．Because it has lost its natural instincts．
B．Because there is not a complete eco-chain．
C．Because there is no space for it．
D．Because uncontrolled hunting has destroyed its natural living conditions．
2.How is the programme of sending several tigers to South Africa getting on?
A．Its effect still remains to be seen．
B．Two tigers can already compete with their wild cousins．
C．Some of the tigers are already on the road to recovering their natural skills．
D．The tigers should be able to recover their instincts completely by 2007．
3.By saying " but they are nothing like their wild cousins", the writer means that ______．
A．they are no longer feared by other wild animals
B．they don't know how to hunt or kill
C．a complete change has resulted in the species because of breeding
D．to reintroduce them into the wild has become an urgent task
