    One of the most exciting and interesting international cities to visit is London, England. Here is a look at four free things to do during a vacation to London.

    Visit the Trafalgar Square

    Built more than 200 years ago, Trafalgar Square is a popular gathering place for locals and travelers, too. The area is close to good shopping and dining opportunities, and there are usually some sorts of public events or celebrations going on there during most weekends.

    Wander Along the Thames

    Visitors wanting to see some great architecture, attractions and views should spend an afternoon walking along the River Thames. The best place to start is at the world-famous London Bridge crossing over the river and you can walk all the way to Westminster Bridge a short distance away. Travelers doing this will find themselves passing by a great many historic buildings.

    Explore the Local Markets

    While purchasing items at any of the open markets in London is not necessarily free, walking through them to view the merchants, their products and the other shoppers is of great fun. Some of the popular open markets in London worth visiting include Spitafields Market, Portobello Road Market and Leadenhall Market.

    Visit the British Museum

    One of the top museums in the entire United Kingdom can be found in London, and it charges no admission for entry. This museum is so highly regarded that it is not only popular with locals and tourists, it is also seen as a major and valuable scholarly resource.

    The lower East Side is neither rich nor beautiful, but it can be a good place to shop.

    On Sundays, its streets are crowded with visitors and shoppers like these. They are trying to find a coat or a pair of shoes at a good price.

    Most people prefer to shop in the big department stores like Macy's, Gimbel's, or Bloomingdale's because there they can find clothing, furniture, toys, and food in one store.

    Some people like the smaller stores of Greenwich Village or other areas when they are looking for an unusual present.

    Some streets have only one kind of stores. Bracelets (手镯) and rings shine in the windows of Canal Street, and wedding dresses fill the stores of Grant Street. There are streets for furs(皮大衣), and, in one area, there are 600 shops for antiques (古玩)! Fifth Avenue is the most famous place to shop, and it is usually the most expensive. There you can find the latest styles from Paris, Italy, or New York. You can spend thousands of dollars on Fifth Avenue, or you can just window shop and admire the sights for free.

    I live a different life in every season. Life in the summertime is often full of pests. Like most Long Island homeowners, I want to ensure my suburban life with pest-free living. So it was with wide-eyed surprise that I greeted the smiling exterminator (灭虫者) who rang my bell.

    “We'll be serving your neighbors, Mike and Sarah (I'm not familiar with either one by name),” he waved in the other direction. “Since we'll have a team here tomorrow, we're offering a discount. ” He came out with numbers beginning from $299 then in seconds to $89.

    “You've probably been seeing the ant hills around.” he moved toward my front walkway and lawn. “And have you seen the bees that dig nests in the ground?” he continued with his head shaking up and down pushing me to do the same.

    “What we do is spray three feet out from your foundation and three feet up.” As he was talking, and without breaking eye contact, he opened his iPad cover and began operating at the screen to show me frightening images. “It also kills other pests, like spiders. It is the best pesticide (杀虫剂),” he said, pausing for effect.

    He then went into soft talk to close the deal, correctly foreseeing that I would be concerned about safety and the environmental impact on my vegetable garden, plants and our little patch of planet here on Long Island. “The products are environmentally responsible, safe with children and pets,” he said.

    I'm unkind when it comes to unwanted visitors entering on my out-of-doors moments. Any insect found in my house or on my deck is bound to be poisoned or pancaked.

    Unfortunately for the exterminator, just as I was considering buying the pesticide, Billy, my fearless husband, pulled into our driveway, which made me ask for a business card out of politeness instead.

    A new study suggests that patients with breast cancer who take additional vitamins during chemotherapy(化疗) treatment may face increased risks.

    Researchers said the use of dietary supplements(补充剂) that increase levels of antioxidants, iron, vitamin B12 and omega-3 fatty acids appeared to lower the effectiveness of chemotherapy. Researchers reported their findings in the Journal of Clinical Oncology.

    Christine Ambrosone is the head of cancer prevention and control at the Roswell Park Comprehensive Cancer Center in Buffalo, New York. She said, "From this study and others in the literature, it seems that it may not be wise to take supplements during chemotherapy."

    "It's thought that antioxidants might interfere with the ability of chemotherapy to kill cancer cells," Ambrosone said.

    Some doctors have been advising patients for a number of years not to take antioxidants during chemotherapy. "But there was no strong empirical data for that recommendation," Ambrosone said.

    So, Ambrosone and other researchers decided to study whether supplement use might affect chemotherapy's effectiveness. They looked for evidence in an earlier study on diet, exercise, lifestyle and cancer results.

    In the earlier research, people who took part were asked about their use of supplements at the beginning of and during treatment, and about their lifestyle, diet and exercise. The researchers studied 1,134 patients who filled out the surveys and followed them for a median of six years.

    The researchers searched for possibilities that might increase the risk of the disease reappearing or of death. They found that patients who took any supplements at the beginning of and during chemotherapy were 41 percent more likely to have their breast cancer return than those who did not. In addition, the supplement takers were 40 percent more likely to die later on compared to patients using no supplements. The supplements included vitamin A, C and E. Those taking vitamin B12 and iron supplements were at greater risk of cancer returning, the researchers said.

For the past 60 years,the African Wildlife Foundation (AWF) has protected animals,restored lost habitats and advocated for policy changes that benefit wildlife.Now,the conservation organization is trying a new approach.

This year,AWF launched the inaugural Benjamin Mkapa African Wildlife Photography Awards.The contest aims to reach a different audience.While photography competitions are nothing new,AWF hopes that the exhibition of winning entries will encourage African people to take a more active role in conservation.Its CEO Kaddu Sebunya said,"Africans need to take responsibility for the conservation of their heritage."

Photographers of all ages and backgrounds,professional and amateur,were invited to submit to the competition.A judging panel,comprised of photographers,conservationists,activists and safari guides,selected photos from 12 categories including "Art in Nature" "Coexistence and Conflict" and "Conservation Heroes".

 The "Conservation Heroes" category had special appeal for Kenyan conservation photographer Anthony Ochieng Onyango."I realized there was a communication gap because most of what was being communicated was data in scientific publications," said Onyango,adding that images are a simple way for people to connect to complex issues.

While there were many entries in the AWF competition,there's only one 19-year-old Cathan Moore from South Africa among the category winners.There's a lack of opportunity for young aspiring photographers on the continent.AWF is seeking grants and partnerships to enable more African people to participate next year,and to make nature photography competitions more accessible to those unable to pay or buy expensive camera equipment,allowing people to use whatever camera they have and photograph wildlife in urban environments.

Sebunya hopes that the competition can open up a dialogue about conservation and why it's so important for Africa's future.Many people in Africa look at conservation as a thing done by and for foreigners,said Sebunya.While he praised the work of international NGOs,he emphasized that it's vital that African voices are heard and for local people to lead conservation efforts.
