This phenomenon confused scientists for years until a recent study found that people tend to sympathize with fellow humans. Supporting this claim was the discovery that those children who were unable to form normal emotional ties with others did not experience contagious yawning, which showed that humans communicate regularly with out words. Hugo Critchley, a neuroscientist, has conducted an experiment recently, which will prove that happiness and sadness can spread like the common cold. According to Critechley, our mind and body are in constant exchange about how we're feeling. "Emotions are closely linked with states of internal responses," he explained. " There are also more visible changes in our gestures and facial expression. When we're in a group, these signals can spread to another person. For example, there's the obvious tendency to smile when smiled at and there are less obvious changes that reflect emotions of surprise, anger or sadness such as a change in our heart rate and blood pressure. Hugo Critchley further explained, "Our bodies synchronies and when we like the other person, we ever copy his behavior. Next time you chat with a friend, take note of how you're sitting-- it's pretty likely that you will be the same. Scientists believe it's our way of telling each other that we're partners. Through body language, humans give each other very subtle but clear signals that show emotions." So, what lessons can we learn from this? " Spend time with happy people-- otherwise your health could suffer," said Critchley." When we're sad, our body goes into fight or flight mode. But when we're happy, our body works normally and we feel relaxed and positive. So we look bright, our skin glows, we feel healthy and it affects everyone around us." Question: From the passage we can learn _ . Options: A: sadness is as contagious as happiness B: anger is less contagious than friendliness C: surprise is more contagious than smile D: surprise is the most contagious among emotions

Article: Tom Sawyer is known as one of the most beloved characters in American literature , but new research found that Mark Twain based this character on his friend named Tom Sawyer. He admired his firefighting friend so much that he gave the character his name. Mark Twain and Tom Sawyer had many adventures together, gambling in Nevada and drinking in pubs. Tom Sawyer once worked as a volunteer firefighter, policeman and customs officer. Before making his way out West, Tom Sawyer used his strength to save 90 people from a burning ship. Mark Twain was particularly moved by this story because his own brother died in a fire while working on a similar steamboat. The two men became friends immediately after meeting in 1863, with Tom Sawyer traveling to Virginia City, while Mark Twain was working as a reporter there. After one night they returned to San Francisco, Mark Twain told his friend that he would base a character in his yet-unwritten book on him. Tom Sawyer said, "One day he said to me, 'I'm going to put you between the covers of a book, Tom.' 'Go ahead, Sam,' I Said, 'but don't disgrace my name.'" Besides their fondness of drinking, the two men also shared a hobby for storytelling. Tom sawyer believed that it was his anecdotes about his own childhood that inspired Mark Twain to create a book on him. Finally Mark Twain said that the character of Tom sawyer was based on a mix of three real people---John B. Briggs, William Bowen and himself. In spite of this, the historical evidence shows that there might be a fourth, more prominent influencer. Question: Mark Twain and Tom Sawyer have the common hobbies EXCEPT _ . Options: A: gambling B: drinking C: storytelling D: drawing

Q: Read the article and select the best answer. Article: As a preteen in New York, Whitney Johnson volunteered at soup kitchens and delivered clothes to the homeless. While at college, she started an English-language tutoring program for immigrant children. No one was surprised, then, when she chose to volunteer in an orphanage in Khayelitsha, one of South Africa's poorest areas, during her junior year abroad. At the orphanage, Johnson discovered most of the children infected with HIV at birth, many abandoned by parents too sick to care for them, or neglected by surviving s. Few were receiving the care needed to stay healthy. Many died. When she left, all she wanted to do was go back and change what she had seen. After graduation, Johnson began a fund-raising effort that eventually collected enough money to found UBA, a nonprofit organization intended to provide services for HIV-positive kids aged 4 to 18 in Khayelitsha. Now UBA is housed in a church big enough for offices and the children. The staff includes counselors , a social worker, a nurse, a cook, and a handful of volunteers, ensuring that each child has access to proper care, a free healthy meal, and emotional support. Once a week, she makes sure the children receive age-appropriate lessons about AIDS. The social worker sees to it that the kids are enrolled in school and have safe living conditions-especially those without parents. Johnson plans to soon relocate UBA to an even larger location with more medical staff and a field"so the kids can run around and just feel like kids." She's also working with the South African Department of Health so that the new center can distribute drugs and give blood tests. "Many people think that HIV means death, but it doesn't," Johnson says. "There's so much that can be done." In the five years since the center opened, not one of the 200 kids in the program has died. "It's so emotional to see the strong, independent people they become." One teenage girl who had received help at UBA even announced that she wanted to become a nurse. Question: After graduating from college, Whitney Johnson _ . Options: A: volunteered at soup kitchens in New York B: went to study abroad for a year C: started an English-language tutoring program D: began collecting money to found UBA
