Two girls living next door to each other-a seemingly plain scene that has two very different life .stories behind it. Chi Zhen, an 18-year-old student in Seville, Spain, used his camera to tell the story of two lives, which went widespread online. Comments on the photos indicate that they have inspired many, to believe that the future is in their own hands. Chi has seen many youths living life without a goal, wasting their time and blaming bad luck for it. Feeling regret for them, he took a series of photos of his friends Veronica and Anna Maria, both freshmen at the University of Seville in Spain. They live completely different life styles and are getting opposite results. Chi hopes the photos will inspire those who have let go of their own fate  . In the photos, Anna Maria, a Spanish girl, can be seen watching a TV programme . She spends most of her time in front of her laptop. She rarely goes out, because she thinks she's not attractive and doesn't know what to say in social situations. "'I'm not as lucky as Veronica," she often says. But she doesn't know that while she's wasting time watching TV, -Veronica, the "lucky" girl next door,has taught herself four foreign languages and traveled to many places. She goes to the library frequently  and her extensive knowledge and experience allow her to take part in any conversation and become the center of attention. Chi thinks that Anna Maria resembles many of his Chinese .friends who study abroad. They are trapped to their little circles, never trying to change their fate./'They say 'maybe I'll do it in my next life', but they are in their 20s, their best time. How can they give up hope and accept this as their life?" Chi says. The influence of the photos has gone far beyond what Chi expected. One user commented on his photos on Renren.com, saying, "A wall separates two worlds, and the life we have depends on what we do." Another is determined to make a change right away. "I'm turning off my laptop and not watching TV anymore," he wrote. It can be concluded from the widespread photos online that   _  ' A) life one has depends on what one does B) Anna is an attractive girl with a goal C) Veronica is much luckier than Anna D) Chi wastes his time in taking photos

Which animal has the fastest snapping jaw  ? If you're guessing a shark or perhaps a larger animal, you'll have to think smaller. The trapjaw ant, which lives in Central and South America, moves its mouth parts at 35 to 63 meters per second. Another way to think about this is that the ant's jaws close at 125 to 233 kilometers per hour. That's 2, 300 times faster than the blink of an eye. Scientists were able to measure the amazing jaw speed using highspeed video techniques. Sheila Patek, a biologist, says the key is that the jaws have a springy   system, which is critical in getting explosive   speeds. Consider a bow and arrow. If you try to throw an arrow with your arm, it won't go very far. If you use a bow, elastic energy stored in the bow is released almost instantly when you release the arrow with your finger or a latch. The combination of the springy bow and latch mechanism is what makes the arrow zoom through the air. Maybe even more amazing than how fast these ants grab food or even enemies is how they use this same energy to move. As the ant closes its jaws, it uses them to push off the ground--all faster than the eye can see without slow motion video. A snap of the jaw can send an ant up to 8.3 centimeters into the air. That's like someone who is 1.7 meters jumping 13 meters high! Not only can they quickly escape from enemies, but often a group of ants will start jumping all at once. It would be hard for their enemies to grab just one. People have suspected the ants used their jaws to jump for over a century, but could only prove it with today's modern video equipment. The passage uses "a bow and arrow" as an example to show   _  . A) how an arrow gets so much energy to fly B) why the trapjaw ants have springy system C) why the trapjaw ants jaws move so fast D) how a bow and arrow works

Sally Ride, the first American woman to fly in space, died on Monday after a 17-month battle with cancer, her company said. She was 61.     "Sally lived her life to the fullest, with boundless energy, curiosity, intelligence, passion, commitment and love. Her integrity  was  ; her spirit was immeasurable; her approach to life was fearless, " read a statement on the website of Sally Ride Science, a company she started to help teach students, particularly young women and girls, about science, math and technology.     Sally flew into orbit aboard the Space Shuttle Challenger in 1983 to become America's first woman in space. She took a second trip aboard the same shuttle one year later. The first woman in space was Soviet cosmonaut Valentina Tereshkova, who orbited the Earth 48 times in 1963. She was assigned to a third flight, but that was cancelled after the Challenger exploded shortly after lift-off in 1986, claiming the lives of seven crew members on board. Sally helped investigate that accident and later  _ of Space Shuttle Columbia, becoming the  only person to serve on the commissions investigating both accidents. In 2003, the Columbia crashed during re-entry into the atmosphere, killing all seven crew members.     "As the first American woman to travel into space, Sally was a national hero and a powerful role model," President Barack Obama said soon after news of her death broke. "She inspired generations of young girls to reach for the stars and later fought tirelessly to help them get there by advocating for a greater focus on science and math in our schools. Sally's life showed us that there are no limits to what we can achieve."     As a Los Angeles native, Ride attended Stanford University, where she earned four degrees, including a doctorate in physics, according to NASA. She joined the agency as part of the class of 1978, the first to include women. Ride responded to an ad in the Stanford student newspaper and was selected from some 8,000 applicants. In Obama's speech, he stressed  _  . A) the model encouragement from Sally B) Sally's interest in space travel C) young girls bright future D) the importance of science and math
