The World Health Organization warns that millions of people are dying every year from indoor air pollution. The WHO finds that poor cooking, heating and lighting technologies are killing millions of people each year.

       Indoor air pollution results from the use of dangerous fuels and cook­stoves in the home. To help fight the problem, the WHO announced new guidelines aimed at reducing household pollutants.

       WHO officials say nearly three billion people are unable to use clean fuels and technologies for cooking­heating and lighting. And they say more than seven million people die from exposure to indoor or outdoor air pollution each year. Of that number, the WHO says about 4. 3 million people die from household air pollution given off by simple coal cook­stoves. Most of the deaths are in developing countries.

        Carlos Dora is Coordinator in the WHO's Department of Public Health, Environmental and Social Determinants of Health. He says people should not use unprocessed coal and kerosene fuel indoors. He says opening a window or door to let out the harmful air will not improve the situation. It will only pollute the outdoors.

        WHO officials say indoor pollution leads to early deaths from stroke, heart and lung disease, childhood pneumonia(肺炎)and lung cancer. Women and girls are the main victims. The United Nations found that more than 95 percent of households in sub­Saharan Africa depend on solid fuels for cooking. It says huge populations in India, China and Latin American countries, such as Guatemala and Peru, are also at risk.Nigel Bruce is a professor of Public Health at the University of Liverpool. He says researchers are developing good cook­stoves and other equipment to burn fuels in a more efficient way.

        WHO experts note some new, safe and low­cost technologies that could help are already available. In India, you can buy an induction(电或磁) stove for about $ 8.00. And in Africa you can buy a solar lamp for less than $ 1. 00.

      Your friends' lives may look more exciting than yours on Facebook，but new research shows that is because they are faking(伪造)it.

      A recent survey has found around two­thirds of people on social media post images(图像) to their personal information to make their lives seem more adventurous.And more than three quarters of those asked said they judged their peers(同龄人)based on what they saw on their Instagram，Snapehat or Facebook pages.

      The British survey，by smartphone maker HTC，found that，in order to make our own pages and lives appear more exciting，six percent also said they had borrowed items to include in the images in order to pass them off as their own.More than half of those surveyed said they posted images of items and places purely to show off，causing jealousy among friends and family.

      Behavioural psychologist Hemmings said the trend was unsurprising due to the rise of social media.“We're living in a world of instant communication.”she said.“Fashion and style used to live and die in magazines；now people are in search of authentic，peer­to­peer recommendations as well，making social media an equal power house to magazines and newspapers.”

    “With images being shared in an instant we desire to know what our friends are wearing，or what super stars are buying, as soon as they have got them.” Such is the influence of social media sites like Instagram,76 percent of those asked also said seeing items on social media influences them to buy them，with men more likely to take style advice and buy what they see.

Tips for Cycle Trips

       Cycling has many advantages as a form of travel, as it is the fastest way to travel by human power and slow enough to allow the type of local involvement that is impossible with powered travel.Cycle travel is a cheap form of transportation.

       Distance

      On level terrain(地形)，without a headwind, a cyclist of average fitness on a touring bike can comfortably cover 60­120km a day.Distances of up to 250km a day are possible, but anything much beyond 120km will require considerable physical tension and not allow many stops to enjoy the places you visit.For many,80­100km a day will be the most suitable distance to aim for, as it will give a sense of achievement and also leave plenty of time for meals and activities.

       Geography

       The gradient(坡度)of the trip will reduce your range.A basic rule is that for every 100 meters of altitude you climb, you should add an extra 15 minutes to your journey time.In hilly or mountainous areas, the easiest routes for cycling are downstream along major rivers, as overall they will be downhill.A long, roundabout route along a river will usually be easier than a short, direct route over a hill or mountain pass.However, it is worth bearing in mind that the most scenic routes often come from hilly terrain.

      Eat

      Food choice depends largely on where you are, so see the respective sections for more information about foods. As you will be working hard, it's important to get enough energy in your food. On long trips away from major towns­there may be little quality food available, so be prepared to live on candy bars, prepared meat products and the like if the need arises.

      Sleep

      While you can take a tent with you, many hotels and especially campsites can accommodate cyclists. However, there are also some hotels that may be less used to accommodating cyclists. If you are exploring an unfamiliar world asking about the accommodation spares you the search for a new place to stay after a long exhausting day of travel.

       Working women make up nearly half of the U．S. workforce, and 51 percent of professional workers, like doctors, lawyers, nurses and accountants, are female. While climbing the career ladder can be rewarding, it often comes with one big downside: weight gain!

      New research published this week in the International Journal of Obesity shows that working women are more likely to be overweight, and the more you work, the more pounds you're likely to pile on. Like many women, I work... a lot! As a self­employed nutrition communications specialist, I sit at my desk, in front of a computer, for hours on end. Sitting alone is one of the worst things you can do for your health, and it's directly linked to being overweight and increased fatness, so the fact that women in the workforce gain weight isn't that surprising. If you work, you have less time to move around. Obesity(肥胖症)researchers are revealing many other ways that employment is harmful to your diet and waistline.

       In the International Journal of Obesity study, some 9,276 Australian women aged 45­50 had their body weight and employment status monitored for two years. Results? Those who worked more than 35 hours were likely to gain weight compared to those who worked fewer hours or were out of the workforce. What's more, the more hours a woman worked in a week, the more weight she gained.

       The authors of the Australian study attribute weight gain among working women to inactivity, lack of time for food preparation, more use of prepared foods, high levels of stress, lack of sleep and consuming more alcohol. I'll also add in travel, meals eaten out and working at night as other factors that I can find to make balancing work with a healthy diet a challenge.

      Louisinvited his friends to lunch one day. He was cooking some delicious food in thekitchen. Suddenly, he(find)that he had run out of salt. So Louis called to his son, “Go to the village andbuy some salt, but pay a fair price for it: neither too much too little.”

      Hisson looked surprised. “I can understand why I shouldn't pay too much, Father,but if I can pay less, not save a bit of money？”

“Thatwould be a very (reason)thing to do in a big city, but it could destroy a small village like ours，” Louis said.

      Louis'sguests, had heard their conversation, asked why theyshould not buy sale more cheaply if they could. Louis replied, “The only reasonwhy a man would sell sale alower price would be that he was desperate for money. And anyone who tookadvantage of that situation would be showing a lack of respect for the sweatand struggle of the man who worked very hard to produce .”

      “Butsuch a small thing couldn't (possible)destroy a village.”

      “Inthe beginning, there was only verysmall amount of unfairness in the world, but everyone added a little, always (think) that it was only small andnot very important, and look where we have ended up today.”

      Minnie was very popular with her friends. Every year, her classmates voted her as their favorite student and she was always 1  of having so many friends.

       One day the 10-­year­-old girl was caught talking and2in class and was ordered to stay back after school as a punishment. She had to help in the school3 for at least one hour. It is also a rule that once in a month the one getting4 could ask a friend to do that for him if he is busy. And of course, he had to5 the favor within the same month.

       It was the last day of that month and Minnie had promised to go to the airport and see her uncle Tom from New York while he was waiting for his connecting 6to Florida. She was sure someone would stand in for her out of 7.

        She turned to Peres, her best friend. But Peres said she had to coach her brother for his8 test. “The kid can't even calculate9 without my help.” She spent a lot of time talking about her brother's learning 10.

     “Morris, could you take my11 this afternoon?” Minnie asked another friend, who often stayed 12at school. “To help the librarian? I have to 13  my cousin's birthday with her family.” and then Morris 14.

        By now, Minnie began to15 if even one of her friends would agree to stay. She tried three more but all of them16. No one said “no”17, but everyone was giving his or her reason why they couldn't stay back for her.

      Finally, Minnie stayed to help the librarian, Mr. King. When he found her unhappy about being unable to keep her18 with her uncle, he allowed Minnie to 19, which turned her tears into a big smile. “You seem to have a lot of friends,” Mr. King said, “But you should 20 that a friend in need is a friend indeed.”

　  An old woman walked around as she pushed her shopping cart full of many things. She was1. Her hair was untidy. Her clothes were torn. And some of her teeth were missing.
