Now, we know that if we do not get enough vitamins, we are at risk of developing a number of diseases. As a result, vitamin supplements ,though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease. In fact, medical experts warn that taking too many of some vitamins can be harmful. For example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines. Experts, however, do say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight. Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly color1ed fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products. In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need. From the passage, we can learn that medical experts advise people _ . A) never to take any vitamin supplements B) to depend only on food for their vitamins C) not to take any vitamins together with medicines D) to consult doctors before taking vitamin supplements

Two European Summer Must 'Seas' When you think of summer,the beach,clear water, sunny skies, and relaxing days are a few things that come to mind, and two of the best places to experience these summer feels are two gorgeous European bodies of water: the Mediterranean Sea and the Adriatic Sea! These two incredible Seas hold some of my favorite travel memories and I would revisit each one in a heart beat! The Mediterranean Sea The Mediterranean Sea can be accessed from various European countries as well as a few North African countries. And while many think of visiting Ibiza, Malta, or the Greek islands to experience the Mediterranean, my Mediterranean beach days came while visiting the seaside city of Marseille in the South of France! Marseille was a lovely city with easy access to the Sea, also with pretty sandy beaches. The gorgeous crystal clear blue water made it unlike any beach day in America! Not only were the beaches amazing, but the city of Marseille was adorable and filled with numerous cute shops and seaside restaurants. And the Mediterranean-style food was delicious! The Adriatic Sea The Adriatic Sea is equally as stunning and surely worth a visit! The Croatian coast has numerous beach clubs, some private and some public, that tourists are able to visit and you can experience the beauty of the Adriatic Sea there! Zrce Novalja, a Croatian seaside town I visited, was impressively featured by the rather rocky beach in place of sand. The rocks were small and smooth, making swimming in the sea and wading in the water just as easy as sandy beaches! Plus the locals in Croatia are also extremely friendly, making the experience even more memorable. What makes Zrce Novalja so special? A) Its beach clubs. B) Its beautiful sea. C) Its rocky beach. D) Its friendly locals.

Ques: It was something she had dreamed of since she was five. Finally, after years of training and intensive workouts, Deborah Duffey was going to compete in her first high school basketball game. The goals of becoming an outstanding player and playing college ball were never far from Deborah's mind. The game was against Mills High School. With 1 minute and 42 seconds left in the game, Deborah's team led by one point. A player of Mills had possession of the ball,and Deborah ran to guard against her. As Deborah was running to block the player, her knee went out and she fell down on the court in burning pain. Just like that, Deborah's season was over. After suffering the bad injury, Deborah found that, for the first time in her life, she was in a situation beyond her control. Game after game, she could do nothing but sit on the sidelines watching others play the game that she loved so much. Injuries limited Deborah's time on the court as she hurt her knees three more times in the next five years. She had to spend countless hours in a physical clinic to receive treatment. Her frequent visits there gave her a passion and respect for the profession. And Deborah began to see a new light in her life. Currently as a senior in college, Deborah focuses on getting a degree in physical treatment. After she graduates, Deborah plans to use her knowledge to educate people how to best take care of their bodies and cope with the feelings of hopelessness that she remembers so well. How did Deborah feel when she first hurt her knee? A) Calm. B) Confused. C) Ashamed. D) Disappointed.

Ques:Children whose minds wander might have sharper brains, a research suggests. A study has found that people who appear to be often distracted have more "working memory", giving them the ability to hold a lot of information in their heads and control it cleverly. Children at school need this type of memory on a daily basis for a variety of tasks, such as following teachers' instructions or remembering dictated sentences. During the study, volunteers were asked to perform one simple task during which researchers kept asking if their minds were wandering. At the end, volunteers measured their working memory capacity by their ability to remember a series of letters mixed with simple maths questions. Daniel Levinson, a professor at the University of Wisconsin-Madison in the United States, said that those with higher working memory capacity reported "more mind wandering during these simple tasks", but their performance did not _ . The results, published online in the journal Psychological Science, appear to confirm former research that found working memory allows humans to deal with multiple thoughts at the same time. Dr Jonathan Smallwood, of the Max Planck Institute for Human Cognitive and Brain Science in Leipzig, Germany, said, "What this study seems to suggest is that, when surroundings for the task aren't very difficult, people with additional working memory capacity use them effectively to think about other things besides what they're doing." Working memory capacity is also associated with general measures of intelligence, such as reading comprehension and IQ scores. Dr Smallwood added: "Our results suggest the sorts of planning that people do quite often in daily life - when they are on the bus, when they are cycling to work, when they are in the shower - are probably supported by working memory." According to the study, working memory _ . A) prevents people from remembering dictated sentences B) causes people's minds to wander more easily C) allows people to consider more things at the same time D) leads to people's worse performance during work
