An American skydiver has survived a 7, 600-meter jump from an airplane, although he did not use a parachute(降落伞). Luke Aikins dropped into a huge safety net on Saturday after falling for about two minutes over the desert in California. Aikins reached a speed of 193 kilometers per hour during the jump. He fell safe into a net. Cranes(起重机) {#blank#}1{#/blank#} (hold) the net about 65 meters over the desert floor. The 42-year-old husband and father has jumped out of planes thousands of times, but never once  {#blank#}2{#/blank#}he left a plane without a parachute. Aikins said he was nervous before this jump. “We're talking about jumping without a parachute,” he told reporters. "I take that very  {#blank#}3{#/blank#}(serious). It's not a joke.” Aikins prepared for two years  {#blank#}4{#/blank#}(make) the jump. Three skydivers with parachutes made the jump with him. They recorded the event with a video and carried the  {#blank#}5{#/blank#} (equip) that Aikins needed, like an oxygen mask. Aikins rolled in the air just moments before he hit the net so as to land on his back. The sky-diver did not move for several seconds as the net was lowered to the ground. Then, Aikins stood, waved his arms and hugged his wife.

    If you study abroad, it's necessary to mix with the locals. This allows you{#blank#}1{#/blank#}(test) your language skills and find out more about the local culture. Having lived abroad for three years, I'm able to put forward a list of tips to help you make friends in a foreign country.

    Firstly, say yes to everything within reason. Obviously, if you don't feel {#blank#}2{#/blank#} ease, you can choose not to do anything. However, don't put off trying something new. The group of students from your class who invite you out for a coffee might end up {#blank#}3{#/blank#}(be) your friends for life!

    Secondly, develop a {#blank#}4{#/blank#} (entire) new hobby. Join a dance class, a walking club or learn to cook the local food—the {#blank#}5{#/blank#}(possibility) are endless!

    Thirdly, get out of the house! Hours {#blank#}6{#/blank#}(spend) on the computer chatting with your family back at home surely make you even homesick. Just get out and explore the exciting place you live in.

    Lastly, be {#blank#}7{#/blank#}(confidence) when you are surrounded by people speaking {#blank#}8{#/blank#} unfamiliar language. Even if you may find {#blank#}9{#/blank#} difficult to involve yourself in conversations, you should try to make your voice heard. Once you open your mouth and begin to speak, it's likely {#blank#}10{#/blank#} you will find everyone wants to know more about you.

    Don Ritchie was a famous Australian man. For nearly 50 years, he successfully stopped 160 people from killing {#blank#}1{#/blank#} (they) at a cliff (悬崖), with just a kind word and a smile.

    Don was a real gentleman, he purposely chose to live right across the street from the cliff, just because he wanted to save lives of {#blank#}2{#/blank#} (stranger). He would wake up every morning and look out of the window for anyone {#blank#}3{#/blank#} (stand) too close to the edge of the cliff. If he saw someone and thought they might jump, he would {#blank#}4{#/blank#} (simple) walk over with a smile and say, "Is there something I could do to help you?" That sounds very simple, {#blank#}5{#/blank#} it worked – Ritchie tried to have a talk with these people and ended up inviting them back to his house {#blank#}6{#/blank#} tea or breakfast.

    In a situation {#blank#}7{#/blank#} most people would turn a blind eye, with such simple actions taken by Don, he saved 160 lives.

    Some misunderstanding is putting shark populations at risk now. Thousands of sharks are dying as {#blank#}1{#/blank#}result of people's false beliefs.

    If you're bitten by a shark, you will be a goner. You are more than twice as likely {#blank#}7{#/blank#}(die) from a lightning strike as from a shark bite, according to the Florida Museum's International Shark Attack File (ISAF). "Even if you are bitten, the large {#blank#}8{#/blank#}(major) of people survive", says Dr. Chapman. There {#blank#}9{#/blank#}(be) sixty-six unprovoked(无端的)shark bite incidents around the world in 2018, only six of {#blank#}10{#/blank#}were dangerous, according to the ISAF.
