Article: While English is getting more important in our schools, Chinese has become popular among foreign kids. But Chinese can be more difficult to learn.

I want to study at Peking University when I grow up." Piao is from South Korea. He came to China in 2008. In South Korea, there are more than 300000 Chinese learners like Piao. Some South Korean students begin to learn to write the language on their first day at school. To help students learn Chinese, South Korea holds speaking competitions for high school students every year. Chinese isn't just popular in South Korea. People from all the world want to learn it. The Chinese Ministry of Education says that nearly 130 million people from 85 countries are learning Chinese. This number will be increasing to 800 million in the coming years.

Article: A dog found shot in the head and face with a pellet gun, stuffed in a garbage bag and left to die is recovering from his injuries at an animal clinic in Texas. The bag containing the 3-year-old male mixed breed was discovered tied to a fence in Conroe, Texas, earlier this month. When local residents opened the bag, the dog appeared, took a few steps and fell. Augustyn rushed the dog to an emergency animal clinic, where he was treated for many pellets to the face, eyes, mouth, neck and shoulders. The dog was stabilized, but according to Dr Ron Hendrick, a vet at the Animal Emergency Clinic of Conroe, pellets remain in both eyes and it's unclear whether the dog nicknamed Buck was left blind forever. A Facebook page, Buck Needs Bucks for His Buckshot Injuries, was launched last week by Augustyn. It was created to help pay for the dog's medical bills. The page has attracted nearly 7,000 "likes" and, according to its creator, already more than enough donations to pay for his treatment. "The last 24 hours has been overwhelming for me," Augustyn wrote on the page. "I have gone from not knowing if I would have enough money to pay for Buck's emergency bill to having an unbelievable amount of money to provide the best possible care for Buck's recovery. I have thought long and hard about this today and how I should handle this. The conclusion is that I will open a separate bank account for Buck and all donations will be used for Buck's recovery and necessities." With the help of Facebook, Buck's story quickly sparked international interest. "Buck is now walking," Augustyn says. Police in Montgomery County say they are investigating the incident, and Augustyn says she has been in contact with law enforcement officials about donating a reward for information leading to the arrest of the person who tortured the dog. Sadly, cases like Buck's are not uncommon, particularly in Texas.
Question: When Augustyn found the dog, it was _ .
Options: (A) being shot by its owner (B) tied to a fence near an animal clinic (C) in a horrible physical state (D) hiding from its owner inside a bag

Article: The story of Juno and Lucas is one of the most touching stories about the amazing relationship between humans and their companion animals. Juno is a Belgian Malinois . The dog was beautiful but was given up by its owners, as they did not want to take on the responsibility. Lucas, a little boy, had a strange illness, a condition that stops the body's ability to process enzymes .As his life continues, he will lose the ability to speak and his physical and mental abilities will degrade till he is left in a vegetative state. The average life expectancy for the patients is 15 years. Chester, the boy's father, wanted his child to enjoy his life on earth as much as possible and looked into getting a service dog for the child. However, Lucas wasn't a good candidate due to his deteriorating abilities, not to mention the $15,000 cost of the animal. Not terrified by all of this, Chester looked into adopting a dog for his son. He found Juno on a website and drove two hours to meet her. Chester had worked with the breed in the police force and was familiar with how to train them. He put in patience and hard work, and trained Juno while allowing her to become accustomed to Lucas. Now, not only will Juno not leave Lucas' side, she is also helping with his illness. Chester said, "She has the ability to notice his neurological changes. Now she reminds us when Lucas is about to have a seizure or if his oxygen levels drop really low. She has saved him several times." Companion animals are beautiful things and they establish a bond that can't be described without experiences. I know that I held my adopted dog a little closer after hearing this story. There are a lot of dogs out there that need good homes and that won't be as lucky as Juno. So, if you think you're prepared, you should consider giving one a nice home.
