Q: Read the article and select the best answer. Article: It's not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study. The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centres are set up. In their study, the researchers examined groups of nine-month-old babies in New South Wales and Britain. And they came across astounding results. It was found that infants had "social brains" and focused not just on their mothers but on social life in groups as well. "They communicate with more than one baby at once, and show jealousy and generousness," said Professor Bradley. He added, "They develop their own meanings through group interaction, they notice if a group member is behaving differently and they take on roles, such as leaders and followers." "A baby who has a depressed mother tends to be withdrawn ( ), but put that same baby in a group of its peers and they behave and interact like any other baby." It was the first all-baby group study ever to be conducted. "Most studies of babies concentrate on the infant-mother relationship, assuming that is the single foundation for mental health, but babies are constantly involved with groups of people other than their mothers, fathers, siblings, grandparents and those taking care. Therefore, the mother-baby approach needs to be combined with a group approach," said Bradley. Phoebe Christison, a child-care worker at Camperdown Sunshine Bubs in Sydney's inner west, said she often noticed what appeared to be emotional attachments developed between toddlers. She said, "Joel ( 10 months ) and Isabella ( 11 months ) always like to hold hands when they sit in their high chairs and eat. And babies definitely show jealousy. They push and touch each other, and copy what the other is doing." Question: What can be inferred from the result of this study? Options: A: There's no need of child-care centers at all. B: Babies are affected by groups more than by their mothers. C: Adults should include babies when having social activities. D: The normal infant-mother bond alone isn't enough for the good mental health for babies.
A: D

Q: Read the article and select the best answer. Article: Six-month-old babies are strictly limited in what they can remember about the objects they see in the world. If you hide several objects from babies, they will only remember one of those objects. But a new study, which was published in an issue of Psychological Science, a journal of the Association for Psychological Science, finds that when babies "forget" about an object, not all is lost. Researchers used to think that babies less than two years old did not understand that an object continues to exist when it is not in the baby's view. But in mid-1980s, new ways of doing experiments with babies found that they do, in fact, know that objects don't disappear when they do not look at them -- a concept known as object permanence. But it was still unknown what babies needed to remember about objects in order to remember their existence. Now Melissa Kibbe, of John Hopkins University, and Alan Leslie, of Rutgers University, are working to figure out exactly what it is that babies remember about objects. For the new study, they showed six-month-old babies two objects, a disk and a triangle. Then they hid the objects behind small screens, first one shape, then the other. Earlier research has shown that young babies can remember what was hidden most recently, but have more trouble remembering the first object that was hidden. Once the shapes were hidden, they lifted the screen in front of the first object. Sometimes they showed babies the shape that was hidden there originally , but sometimes it was the other shape, and sometimes the object had _ completely. Psychologists measure how long babies look at something to see how surprised they are. In Kibbe and Leslie's study, babies weren't particularly surprised to see that screen had changed, for example, from a triangle to a disk. But if the object was gone altogether, the babies looked significantly longer, indicating surprise at an unexpected outcome: "This shows that even though babies don't remember the shape of the object, they know that it should continue to... Question: Before the study, which of the following was unclear? Options: A: Whether babies know objects are gone. B: What made babies remember objects' existence. C: Whether babies can remember what was hidden first. D: Why babies were interested in what was hidden.
A: B

Q: Read the article and select the best answer. Article: Although the New Year is already here, the great moments of the past year are still in the memory. Let's look back at some of them. United States One of the world's largest New Year's Eve parties was held in Times Square, New York. The festival attracted hundreds of thousands of people to watch a brightly-lit ball drop on a landmark building at the stroke (, ) of midnight. A great amount of confetti was released from the sky at zero o'clock. Britain Painted in shinning colors, blowing whistles, 50,000 party-goers arrived in London's Millennium Dome to dance in the New Year. The Millennium Dome came to life at midnight as 50 DJs started up, competing on five separate dance floors to warm the crowd into the party mood. Russia New Year is the biggest holiday in Russia. It is traditional to put up a tree for celebrations with family and friends. On the very last day of last year, Russians with a taste for a very cold swim braved freezing temperatures to plant traditional, festival trees on the bed of the Northern Ocean and at the bottom of Lake Baikal, the world's deepest lake. Malaysia Brave skydivers threw themselves off the world's tallest building near midnight and floated towards the New Year. The jump from the 452-metre Petronas Twin Tower was called a real leap from one year to the next since the group took off in the last second of the old year and landed a minute later in the New Year. "That was really cool," said Roland Simpson, "over crowds of onlookers to the landing spot." Question: In New York the brightly-lit ball dropped _ . Options: A: form the sky onto the Times Square B: into the hundreds of thousands of watchers C: to welcome the arrival of Christmas D: at the point between the old and the New Year

Q: Read the article and select the best answer. Article: To most of us,school means classes,teachers,schedules,grades,and tests.But for the children at Sudbury Valley School in Massachusetts,school is very different. Firstly,there are no lessons.All the children,aged between 4 and 19,do whatever they want.There are no teachers--only "staff members".The idea behind this is that you do not need to make children learn,because children want to learn anyway."You do not need to say to a three yearold,'Go explore your environment.'You can't stop them!" says Daniel Greenberg,a founder of the school."But if you make children do what you want all day,they will lose all taste for learning." At Sudbury Valley School,you will permit children to talk,read,paint,cook,work on computers,study French,play the piano,climb trees or just run around.Two boys spent three years just fishing! The other way that Sudbury Valley School is different is that the children can decide the rules.Every week,there is a school meeting where both children and staff have one vote each--even the fouryearolds.They decide the school rules,how to spend the school budget,and even which staff they want and do not want any more. When the school first opened in 1968,people said it would never work.But today,the school has 200 students,and 80%of its students go on to college. Even the two boys who went fishing all the time have successful careers today.One of them is a musician and the other is a computer scientist. Question: What does Daniel Greenberg say about threeyearolds? Options: A: They love learning. B: They are very naughty. C: They want to be outside all the time. D: They are too young to learn anything.
A: A
