Parents who help their children with homework may actually be bringing down their school grades. Other forms of prenatal involvement, including volunteering at school and observing a child's class, also fail to help, according to the most recent study on the topic.

    The findings challenge a key principle of modern parenting(养育子女) where schools except them to act as partners in their children's education. Previous generations concentrated on getting children to school on time, fed, dressed and ready to learn.

    Kaith Robinson, the author of the study, said, "I really don't know if the public is ready for this but there are some ways parents can be involved in their kids' education that leads to declines in their academic performance. One of the things that was consistently negative was parents' help with homework." Robinson suggested that may be because parents themselves struggle to understand the task." They may either not remember the material their kids are studying now, or in some cases never learnt it themselves, but they're still offering advice."

    Robinson assessed parental involvement performance and found one of the most damaging things a parent could do was to punish their children for poor marks. In general, about 20% of parental involvement was positive, about 45% negative and the rest statistically insignificant.

    Common sense suggests it was a good thing for parents to get involved because "children with good academic success do have involved parents ", admitted Robinson. But he argued that this did not prove parental involvement was the root cause of that success." A big surprise was that Asian-American parents whose kids are doing so well in school hardly involved. They took a more reasonable approach, conveying to their children how success at school could improve their lives."

    Every day, a homeowner in Pennsylvania is reminded of a mistake he made 13 years ago. At around 8 in the evening, his peaceful house comes alive with the noise of an alarm clock he dropped into the wall over ten years ago. It's been stuck in the wall ever since.

    13 years ago, Jerry Lynn wanted to make a hole through his living room wall, so he could pass the television cable (电缆)through it. He didn't want to destroy any pipes in the wall, so he came up with a good idea to make sure that he was drilling(钻孔) in an empty place. He took his alarm clock, tied it to a string(线) and set it to go off in 10 minutes. Then he lowered it into the wall, and waited for it to ring. His goal was to drill a hole in a safe place near the place where the ringing was coming from, making sure that there was nothing to pass through there. It all went smoothly until the alarm clock fell into the wall.

The man didn't get back the alarm clock, but thought it would probably run out of battery(电池)in several months, so he wasn't too worried about it. But 13 years later, the alarm clock still rings every day.

    As you can imagine, Jerry and his wife have gotten used to the ringing living room wall, but it can still surprise  guests. So Jerry decides to pull down that wall, just to stop that boring thing, though after putting up with it for 13 years, he think it will be a pity. He says, “I've never herd of a clock battery lasting that long and my friends think it may be interesting to see how long it will keep ringing for.”

    India has a very vast history and heritage（遗产）. The country has witnessed some of the most important events in the past and every event has an effect of its own on the culture, religion, lifestyle, and economy of the country. This is one of the leading reasons why tourists prefer India to travel and explore. Historical tours in India provide everything that a traveler expects from his/her journey. These historical tours give an opportunity to study and explore Indian history.

    Historical tours of India generally consisted of four phases: ancient, medieval（中世纪的）, modern India and contemporary（当代的）India. Some of the historical travel packages are:

    Forts and Palaces

    The rich cultural past of India is reflected in the countless（无数的）forts and palaces across the country. Most of the forts were constructed as a defense device to keep the enemy away and palaces were made on the names of the kings and queens. Some of the famous forts and palaces are: Agra Fort (Agra), Fatehpur Sikri (Agra), Hawa Mahal (Jaipur), Amber Fort (Jaipur), City Palace (Jaipur), Gwalior Fort (Gwalior), Mysore Palace (Mysore), Red Fort (Delhi), etc.

India Heritage Tours

    The main purpose of India Heritage tours is to make Indians as well as tourists familiar with the rich Indian legacy（遗产）. The heritage of the country is at least 5000 years. Some of the heritage tours are: medieval heritage, Rajput heritage, Golden Triangle, splendid Gujarat, etc.

    South India Historical Tours

    The Southern India is known for its diversity and there are many places, which attract tourists, not only from the country but also from all around the world. The famous tourists' destinations（景区）in South India include Goa, Cochin, Kerala, Munnar, Periyar, Kottayam and the list goes on and on.

    Disease, poverty, hate, love — Charles Dickens' stories opened his readers' eyes to the most important themes of his age. Two hundred years later, his stories still speak volumes across the world, proving that Dickens' legacy (遗产) was far greater than just "great-literature".

    February 7 marks the 200th anniversary of the writer's birthday. To mark this date, BBC writer Alex Hudson listed six things Dickens gave the modern world. Let's take a look at two of them.

    A White Christmas

    Dickens is described as "the man who invented Christmas"— not the religious festival, but the cultural aspects that we associate with the festive season today.

    In the early 19th century, Christmas was barely worth mentioning, according to critic and writer Leigh Hunt. The committee which ran the Conservative Party even held ordinary business meetings on Christmas Day — unthinkable in the West nowadays, when everyone but the most necessary workers takes at least three days off.

    Many people believe that Dickens' popular descriptions of the festive period became a blueprint for generations to come. In his classic novel, A Christmas Carol, he not only put forward the idea of snow at Christmas, but also painted a picture of glowing warmth —“home enjoyments, affections and hopes".

    In his biography of Dickens, Peter Ackroyd wrote:" Dickens can be said to have almost single-handedly created the modern idea of Christmas."

    "Dickensian" poverty

    Dickens was one of the first to take an honest look at the underclass and the poor of Victorian London.

    He helped popularize the term "red tape" to describe situations where people in power use needless amounts of bureaucracy (官僚作风) in a way that particularly hurts the weaker and poorer members of society.

    "Dickensian" has now become a powerful word for describing an unacceptable level of poverty. In 2009, when the president of the Association of Teachers and Lecturers in the UK wanted to talk about poverty in some areas of Britain, she did not use words like "terrible" or "horrific", but rather described it as "life mirroring the times of Dickens".

    The summer I turned 16, my father gave me a car, which permitted Hannah and me to drive around Tucson whenever we wanted to.

    Hannah was my best friend. "Hannah's amazing," my mother always said. And sure enough, that summer she signed with a modeling agency. She was already doing runway work.

    One day, Hannah and I went to the movies. On the way home, we stopped at the McDonald's drive-through, putting the fries on the seat between us to share. "Let's ride around a while," I said. It was a clear night, moonlight shone over the desert. Taking a turn too fast, I hit a patch of dirt and fishtailed.

    French fries on the floor. An impossible amount of blood on Hannah's face. They took us in separate ambulances. In the ER, my parents spoke quietly Best plastic surgeon in the city. End of her modeling career.

    We'd been wearing lap belts, but the car didn't have shoulder harnesses. I'd cracked my cheekbone: Hannah's forehead had split wide open. What would I say to her?

    When her mother, Sharon, came into my hospital room, I started to cry, bracing myself for her anger. She sat beside me and took my hand. "I almost ended my best friend when I was your age," she said, "I totaled her car and mine."

    "I'm so sorry," I said.

    "You're both alive," she said, "The rest is window dressing." I started to protest, and Sharon stopped me. "I forgive you. Hannah will too."

    Sharon's forgiveness allowed Hannah and me to stay friends throughout life. I think of her gift of forgiveness every time I want to resent someone for a perceived wrong. And whenever I see Hannah, the scars are a symbol of grace for me.

    Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time; if corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people's. In the same way, children learn to do all the other things without being taught to walk, run, climb, whistle, ride a bicycle…They compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake. If it is a matter in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time in such routine(日常的) work? Our job should be to help the child when he tells us that he can't find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what he does not know.
