President Barack Obama rode a bicycle at the White House Science Fair on April 22. But it wasn't an ordinary bike. As he pedaled, the President stayed in place, while the energy from his pedaling powered a water filtration system. He was testing an invention created by a team of 14 students from Northeast High School, in Oakland Park, Florida. Payton Karr, 16, and Kiona Elliot, 18, attended the fair as representatives of the project."We were hoping President Obama would ride the bike, but we didn't actually expect him to," Payton told TFK. " It really meant a lot." Kiona agreed. "It was pretty awesome to see the invention, which was invented by a group of 14 high school students and one teacher, along with the help of community members, got the interest of the leader of our nation," she said. The project was an idea that came about after one of the Northeast students, Kalie Hoke, visited Haiti after the terrible 2010 earthquake and saw how difficult it was to find clean water. The students invented a portable , bicycle-powered emergency water filtration system, which can provide 20-30 people with drinking water in a 15-hour period. The teens hope their invention will one day be used by relief organizations like the Red Cross. " They can take it to places after natural disasters so that water can be clean for the people there," said Payton. Payton and Kiona were among the 100 students from more than 40 states invited to the third annual White House Science Fair, in Washington, D.C., which is also attended by leaders in science and education. President Obama started the event in 2010 to _ students interested in STEM (Science, Technology, Engineering, Maths)."Well, if you're a young person and you produce the best experiment or design, you ought to be recognized for that achievement," Obama said when he first announced the fair. President Obama praised the projects during a speech to attendees after the fair. "The science fair projects of today could become the products and businesses of tomorrow," he said.... The representatives of the bicycle-powered water filtration system _ . A) were both community members B) graduated from a famous university C) finished the project with the help of their parents D) were surprised that their invention interested Obama

I stole your dog today. No, I didn't set a foot on your house, but from the condition of your dog, I can imagine what it looks like...the word "rubbish" comes to mind. I found her along a road, with a heavy chain wrapped around her neck, still attached to rotten boards from her doghouse. Not only did I know that most of the town people had already ignored her, judging by where I found her, but I knew that if she had gotten into the Woods, the "cross" that she dragged behind her would have wrapped around a tree until starvation or thirst killed her. She has a beautiful name now. Already in the first week she has come to look more like she should. Her eyes sparkle and she has learned to wag her tail in greeting. She has stopped flinching when I make a sudden movement, because she knows now that I won't beat her, in fact, she rarely leaves my side. She's even become brave enough to bark at a cat and today I watched from the window as she attempted to play with the other dogs. No, it's clear she does not miss you or her former life on a chain. It's not clear yet whether she'll remain here or whether I'll find her a loving home where she can count on more individual attention than I can give her, but one thing is certain, this is one bit of stolen "property" who is never returning to you. So sue me, accuse me, plead with the courts that she is rightfully yours ... I'm convinced this is the best "crime" I've ever committed. Hardly anything has pleased me more than the day I stole your dog. I need only look into her beautiful brown eyes to know that she'd defend my decision with her life. If we have one prayer, it is that you will not replace her, and if we have one special day to celebrate together, it is the day I stole your dog and the day she stole my heart. What's the purpose did the author write the passage? A) To warn the people in the town not to keep dogs. B) To prove his love to the dog to her former owner. C) To explain to the police why the dog were in the Woods. D) To ask people to find the dog a loving home and a owner who loves dogs.

Ques:MERS, also known as Middle East Respiratory Syndrome, has made its way to the US. The second patient was in Orlando, Florida while the first reported case was in Indiana. Tom Frieden, director of the Centers for Disease Control and Prevention, said the disease has mainly been transmitted by close personal contact, such as directly caring for a very ill person. The virus is formally called MERS-CoV because it's part of the corona virus family that includes the common cold and severe SARS. SARS was ly easy to stop a decade ago, because it was being transmitted by caged animals in Chinese markets. MERS-CoV was first identified in people in 2012, but has been spreading rapidly since March, 2015. The vast majority of those cases occurred in Saudi Arabia. The patient in Orlando felt ill on the first flight but not ill enough to notify a doctor. Early on May 9, he apparently became concerned that he was still feeling ill, and he went to the emergency room at Dr. P. Phillips Hospital. He identified himself as recently having been in Saudi Arabia, so he was quickly isolated to avoid infecting other patients. Wayne Marasco, an expert at the Dana-Farber Cancer Institute and Harvard Medical School, said his biggest concern about MERS-CoV is how little we know about it. It's still not clear, in some instances, where the virus comes from, how it is transmitted or who is most subject. This passage is written to _ . A) inform us of more information about the deadly illness MERS. B) caution us against SARS C) call on us to start a campaign against MERS D) appeal to us to understand the medical expert's biggest concern about MERS-CoV
