To help the environment, many Americans have made the change from paper and plastic bags to reusable shopping bags.But a report by a Florida newspaper says that reusable shopping bags sold by some supermarkets have high levels of lead(铅), which can be dangerous to humans, especially young children.Now, there's a call for a rethink about the use of reusable shopping bags.

     “When our families go to the store looking for safe and healthy foods, the last thing they should be worrying about is a bag，”Charles Schumer, a government official said.“Quick and complete research will allow everyone to make right decisions.”

    The newspaper bought more than a dozen bags sold at Publix supermarkets from Florida supermarkets to test them for lead.The results showed that certain bags had lead levels that worried health officials.Some bags had enough lead in them to be considered dangerous waste if people were to throw the bags out with other rubbish.Lead in the bags is not likely to move onto food.But over time, paint (油漆) on the bags can break off and the bags can wear out.When this happens, lead can be freed.

    The affected (受影响的) bags were found in Florida.But Publix has more than 1，000 stores across America.Publix says that its bags don't break any laws about lead levels, but that they have asked the makers of the bags to reduce(降低) the lead levels in them.

    The bags with the highest levels of lead had beautiful designs and many pictures.Plain reusable bags without them are found to have little lead.People worried about lead levels in reusable bags can turn to cloth.Paper bags are also a good choice, since paper can be reused.

    Finding summer jobs for teenagers has not always been easy, but now you no longer have to worry about what your kids can do to earn their own money. Recently I found some different sites online that offer information about what kids can do. Below issome of that information, along with questions to think about to help you come upwith your own ideas.

Ideas for summer work:

●Parks and Recreation Programs.

●Babysitting (当临时保姆) during the day of school.

●Working part-time at a day care for the summer.

●Car washing.

●Working at local vegetable stands.

    The easiest way for you to find ways for your child to make money is to think about others' inconveniences (不方便). Think of things you need done, or would like to have done, and what you would consider paying for these things to get done. Once you have some ideas, you can sit down with your children and talk to them aboutwhat they would be interested in doing. Then once you have an idea of what theywant to do you can help them come up with fair prices.

    Preferably you would want to only have your child working with people you know and trust, or in the least bit you could have your child pick a partner. That way with each of them carrying cell phones, even those without service can call 911, they will be much safer.

    The Indian government may use 3D paintings as virtual (虚拟的) speed-breakers on major highways and roads, in an attempt to check speeding and careless driving, and eventually make its deadly roads a little safer. “We are trying out 3D paintings used as virtual speed breakers to avoid unnecessary requirements of speed breakers (减速带),” India's transport minister Nitin Gadkari tweeted.

    The visual illusions (幻象) are supposed to encourage drivers to slow down automatically. Earlier this month, India bad ordered the removal of all speed breakers from highways, which are considered to be a danger to safety for high-speed vehicles.

    India has the highest number of road accident deaths in the world According to the World Health Organization, over 200,00 people are killed by road accidents due to poor application of road safety laws. This is considerably higher than its official figures of 141,526 for 2014.

    The use of visual illusions as speed breakers was first pioneered in the American city of Philadelphia in 2008, as part of a campaign against speeding motorist. The technique has also been tried out in China to create floating 3D crossings.

    India, cities such as Ahmadabad and Chennai have already experimented with 3D zebra crossings in the last one year. In Ahmadabad for instance, two artists, mother and daughter have painted 3D crosswalks in the first few months of this year. The artists say their motto is “to increase the attention of drivers”, and that the concept has been successfully tested in zones where accidents easily occur on a highway.

    However, critics argue that once divers know that these speed briers are visual illusions, they may ignore them. Others also point out that India's decision does not consider the safety of a large walkers. In the end, the new policy may be just one step towards improving road safety.

    One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem — inability to read.

    In the library, I found my way into the “Children's Room.” I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.

    There on the book's cover was a beagle which looked identical to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.

    Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.

    My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.

    I never told my mother about my “miraculous” (奇迹般地) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.

    September is an exciting month in every college freshman's life. For many, it's the first time that they've left home to live in a new environment. But after the hustle and bustle（喧嚣）of a few weeks, excitement gives way to a less enjoyable emotion— homesickness.

    Homesickness manifests（显露）itself in many ways. You may miss mum's cooking, your pets, or even your old bed. All this becomes a fond memory of the past. Homesickness can be a bitter feeling for many students, especially when faced with the challenges of settling into an unfamiliar environment.

    But remember, you're not alone. According to a recent BBC article, 70 percent of British college students experience homesickness. In this increasingly globalized world in which people migrate to faraway places for a relationship, education or work, homesickness is a feeling shared by many adults.

    Homesickness can have similar symptoms to depression and in extreme cases it can develop into a panic attack. As for the term, homesickness or nostalgia wasn't invented until the 17th century. It was considered a disorder by a Swiss physician, who attributed soldiers' mental and physical discomfort to their longing to return home, “nostos” from Greek, and the accompanying pain, “algos”.

    Studies in recent years, however, have shown that nostalgia may have some benefits to our mental health. After a decade of surveys and researches, Constantine Sedikides, a US social psychologist, found that nostalgia is what makes us human. He explains that nostalgia can resist loneliness, boredom and anxiety. Therefore, it's necessary for college students to learn some ways to overcome the uncomfortable feeling.

    The American dream is the faith held by many people in the United States of America that through hard work, courage, creativity and determination, they can achieve a better life for themselves. More specifically, they agree on how to get ahead in America: get a college education, find a reliable job, and buy their own house. But do Americans still believe in that path, and if they do, is it attainable?

    The most recent National Journal poll(民意测验，投票) asked participants about the American dream, what it takes to achieve their goal, and whether or not they felt the control over their ability to be successful. Obviously, the results show that today, the idea of the American dream and what it takes to achieve it looks quite different from it did in the late 20th century. By the large, people felt that their actions and hard work — not outside forces — were the deciding factors in how their lives turned out. But the participants had definitely mixed feelings about what actions make for a better life in the current economy.

    In the last seven years, Americans have grown more pessimistic about the power of education to lead to success. Even though they see going to college as a fairly achievable goal, a majority 52 percent think that young people do not need a 4-year college education in order to be successful.

    Miguel Maeda, 42, who has a master's degree and works in public health, was the first in his family to go to college, which has allowed him to achieve a sense of financial stability(稳定) his parents and grandparents never did. While some, like Maeda, emphasized the value of a degree rather than the education itself, others still see college as a way to gain new viewpoints and life experiences. Sixty-year-old Will Fendley, who had a successful career in the military and never earned a college degree, think “personal drive” is far more important than just go to college. To Fendley, a sense of drive and purpose, as well as an effective high-school education, and basic life skills, like balancing a checkbook(支票簿), are the necessary elements for a successful life in America.
