Renaissance is a French word. It means “rebirth”. It's a strange name for a period of history. What was exactly “ reborn” during the Renaissance?

    To answer this question, we need to look back at the time of the Roman Empire. At this time Roman artists, scientists and writers influenced by Greek ideas were the world's most advanced. They had become skilled observers of the natural world around them, and had become experts in studying animals, plants, the human body or the stars and planets. They wrote down their ideas about what they saw, and based their theories about the world on their observations.

    During the fourth and fifth centuries the Roman Empire slowly broke down. Many of the Romans' art and sculptures were destroyed and some manuscripts（原稿）were lost as well. But most importantly, some of the ancient attitudes were lost. A questioning approach to the world was replaced by an unquestioning one.

    Why did this happen? One reason was to do with the influence of the Christian Church. Through the thousand years following the fall of the Roman Empire, the Church controlled many aspects of life including education and learning. The Church ran all the universities and thought that the aim of a university should be to teach old ideas more clearly, not to introduce new ones. The scholars in the universities were expected to study God and heaven from the Bible and ancient books, rather than the world around them.

Take medicine for example. The main textbook for doctors had been written by a Greek doctor called Galen more than a thousand years earlier. But when Roger Bacon, a thirteenth-century priest（牧师）, said that a new approach to medicine was needed — doctors should do their own original research instead of reading writers from the past such as Galen-the Church put him in prison.

    By the time of the fourteenth century, however, some parts of the Christian Church were becoming less strict about their ideas and there was a new state of mind among artists, doctors and scientist. People wanted to find out more about the world by studying it. This attitude of investigation had been common in classical scholars, and it was ‘reborn' during the Renaissance.

    Nearly all of us have a bad habit, whether we know it or not. Some people say they want to get rid of (去除) it but don't know the proper ways. Here's some advice on how to get rid of bad habits.

    Make a list. Write down all the reasons why you want to stop a certain behavior, how it's hurting you and why to get rid of it, this will help a lot. Look at that list regularly.

    Join in other activities. It's wise of you to do something else when you want to stop your bad habit. If you get angry easily, for example, you can practice having a deep breath or going for a walk.

    Give yourself a present. Before you take action against a bad habit, decide what you'll do to celebrate it if you reach your goal.

    Keep off bad habits. If you are fat and want to lose weight, keep junk food out of your house. If you are a heavy smoker with coffee, turn to tea and keep away from friends who like smoking.

    Be patient. Bad habits develop over years, so you probably won't be able to get rid of them quickly. In fact, people often give up several times before being successful, so you should be patient.

    Find support. Don't be afraid to ask for support from friends, family or other people who have the same bad habits as you. When you talk to others, they might be able to provide advice or encouragement that you usually wouldn't get from yourself.

    Parents who help their children with homework may actually be bringing down their school grades. Other forms of parental 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."

    In 1999, 36­year­old Tori Murden McClure became the first woman to row also (单独地) across the Atlantic Ocean, from the Canary Islands to the Caribbean. The journey of just over 5,300 kilometers took the American 81 days. Her boat, The American Pearl, was only 7 meters long.

    McClure is a real adventurer. She has been on many mountaineering expeditions, including climbs in Alaska, Kenya and Antarctica. She was also the youngest person in a team that skied 1, 200 kilometers across Antarctica to the South Pole in 1989, and became one of only two women ever to travel to the Pole by land.

    The journey across the Atlantic was her third attempt. The first time she failed because of illness, and during her second attempt, in 1998, she nearly died. She had rowed nearly 5,000 kilometers when her boat was hit by Hurricane Danielle. McClure was suddenly in the middle of 80 kph wind, and surrounded by waves that were 20 meters high. Her little boat turned over five times. McClure was sure that she was going to die­she took the video recorder that she had brought with her and recorded a farewell message to her family and friends. The hurricane continued into night, and The American Pearl turned over five more times. McClure was determined not to send a signal asking to be rescued­she didn't want other people to risk their lives, too. But after the eleventh turning over of her boat, she finally sent it and a large ship came and found her. However, they couldn't get her boat out of the rough sea­it was found months later near the coast of Portugal.

    Tori McClure had concussion (脑震荡) and a dislocated shoulder when she got home. Many people might have given up after an experience such as this, but one year later, McClure was back in her repaired boat and trying again. This time she was successful­and although she again met a hurricane on the journey, which stopped her from breaking the record for the fastest transatlantic (横渡大西洋的) rowing crossing, she only overturned once!

    "What kind of rubbish are you?" This question might normally cause anger, but in Shanghai it was brought about weary complaints over the past few months. On July 1st, the city introduced strict rubbish-sorting regulations that are expected to be used as a model for our country. Citizens must divide their waste into four separate categories and put it into specific public bins. They must do so at scheduled times, when monitors are present to ensure that rules are obeyed and to examine the nature of one's rubbish.

    Violators could be hit with fines of up to 200 yuan ($29). For repeat violators, the city can add black marks to their credit records, making it harder for them to obtain hank loans or even buy train tickets.

    Shanghai authorities are responding to obvious environmental problem. It produces 9 million tons of garbage a year. But like other cities in china, it lacks a recycling system. Instead, it has relied on rubbish pickers to pick out whatever can be reused. This has limits. As people get wealthier, fewer of them want to do such dirty work. The waste, meanwhile, just keeps piling up. China produces 80 billion pairs of one-off chopsticks a year.

    Many citizens appear to support the idea of recycling in general but are frustrated by the details. Rubbish must be divided according to whether it is food, recyclable, dry or hazardous(有害的), the distinctions among which can be confusing, though there are apps to help work it out. Some have complained about the rules surrounding food waste. They must put it straight in the required public bin, forcing them to tear open plastic bags and toss(投掷）it by hand, Most annoying are the short periods for throwing trash, typically a couple of hours, morning and evening. Along with the monitors at the bins, this means that people go at around the same time and can keep an eye on what is being thrown out; no one wants to look bad.
