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.

    Eating healthy 100% of the time can seem like a near impossible goal. But along with consistent exercise, healthy eating will make you feel better, give you more energy, and help you perform better in your workouts. {#blank#}1{#/blank#}

    Here are some tricks to make healthy eating easy:

    ● {#blank#}2{#/blank#}

    Protein is what keeps you full, fuels your muscles, and helps you keep a strong and slim figure. Starting your day out with around 30 grams of protein will not only help get you through the morning without feeling hunger pains, it will also help you get less desires for sugar and carbs(碳水化合物)later in the day.

    ●Make veggies a main part of every meal

    {#blank#}3{#/blank#} You'll find that you might actually start to like vegetables, and your body will start to want them because of how good they make you feel after eating them.

    ●Eat whole foods whenever possible

    Simply focus on avoiding processed foods and include as many whole foods as possible in your diet. {#blank#}4{#/blank#} But once you discover how food is supposed to taste, eating healthy will become much more natural to you.

    ●Don't deny yourself your favorite foods

    {#blank#}5{#/blank#} Because it'll cause you to feel bitter, more often leading to a binge(大吃)eating session. So if you're working out and keeping active on a regular basis, allowing yourself a few small treats every once in a while will not only make you happier, it will also make it more likely that you'll stick with healthy eating in the long run.

A. So want exactly are whole foods?

B. It may take a little to get used to

C. And it doesn't have to be that difficult

D. Limit them, but don't cut them out altogether

E. There are so many good ones to choose from

F. Eat a protein-packed breakfast every morning

G. Make them a main part of every meal, at least two thirds of your plate as often as possible

    Summer is the season to dive into new activities and relax. And right now is the time to make sure that you're ready for the great outdoors, the holiday planning and travel, and the bathing suit beach days.

    If you want to lose weight before summer, concentrate on dropping no more than a pound or two a week.{#blank#}1{#/blank#} And when you trouble yourself, sooner or later you，re going to gain it back. Operate on a 500-calorie-a-day deficit (亏损).{#blank#}2{#/blank#} So if you cut 500 calories a day for seven days straight, you'll lose a pound a week right there.

    Operating at a decrease of 500 calories a day should involve both eating less and moving more. For example, you could consume 300 fewer calories and bum 200 extra per day.

    Include both healthy eating and exercise in your weight-loss plan, and break the 500-calorie goal into small groups to make it more reachable.{#blank#}3{#/blank#}

    To cut 100 calories:{#blank#}4{#/blank#} Have vegetable pizza instead of pepperoni (意大利辣香肠). Use our Nutritional Needs Calculator to determine how many daily calories you should consume in order to lose, gain, or maintain your healthy goal weight. Once you've reached your goal, recalculate your nutritional needs for keeping extra weight off all summer long.

    To burn 100 calories: spend 15 minutes biking. {#blank#}5{#/blank#} Spend 20 minutes gardening. Keep on exercising at least 30 minutes daily a week. Reading food labels and counting calories or writing down what and when you eat can give you more control as well.

A. Here are some simple ways to get there.

B. Walk or run one mile.

C. A pound is 3,500 calories.

D. It is okay to have some snacks between your meals.

E. You should always make sure you get a lot of sleep.

F. Anything more than that usually means you're troubling yourself.

G. Eat a chicken breast without the skin.

    “Oh，my god.Are you serious?”

    That's a reaction I often get when people hear the tale of my childhood.

    It's a story I don't often share.Growing up in a bad home, I learned to protect myself by not speaking up.I've seldom said anything about how badly I was treated and hurt as a child. I don't talk about how my name was changed at least three times, what it was like to live in my van(箱式货车), or how I've struggled with anxiety, depression, and wanting to kill myself. But I learned to start speaking up for myself. I went on to earn two graduate degrees and I will complete my Doctor's degree this year. I've also become a widely published author. So，how did I get to where I am today?

    What's helped me is surrounding myself with caring, loving people. I've learned day-to-day skills through research, trial and error, and with the help of skilled professionals. They've taught me how to slow down，to breathe，to be thankful for what I've got.They're the ones who make my goals possible.They have also taught me to turn my past experiences into strength-to make the negatives into positives.

    My hope is that sharing my story might help others to see what is possible even in the darkest of times and help others to speak out.I don't think I'm in any way special or unique. I'm a common man，no more deserving than anyone else.But for far too long，I've been afraid that others think I'm damaged goods.I've worried about how I might be treated differently.

    Pain and fear teach us to be silent.It's time for that to change.

    I don't know what tomorrow might bring.But one thing I've learned is that if we can hold on and find help，if we find ways to get through the day and speak up，we'11 not only survive，but become stronger than before.

    Our very survival can be an inspiration all on its own.And with love of my friends，I look forward to so much more than completing my education—I look forward to the future.

    Listening to audio books(有声读物) is a really terrific way to enjoy all kinds of books during those times of the day when stopping to sit down and read a book is not an option. An audio book gives the listener hours and hours of entertainment or instruction, or sometimes both at the same time. They are great for people of all ages and make a long road trip a more interesting experience, instead of being boring and dull.

    The biggest benefit of an audio book is that it can be listened to anyplace and anytime. It is a favorite companion for people while they are traveling, commuting, exercising, shopping, working in the garden, or even dusting and vacuuming the house. Using headphones with your favorite audio book player allows you to listen to and absorb the information no matter what might be going on around you.

    Even when you are in a situation that is quiet and are able to enjoy a good audio book, there are still advantages of using your headphones. You can often improve your retention(记忆力) and comprehension of the material when you use headphones because they help reduce distractions from other noises and help you focus better.

    There are a number of different audio books these days that people can choose from. There are audio books on CDs, on audio cassettes(盒式磁带) and also as MP3s and any standard CD player, cassette recorder, or MP3 player that you might use to listen to music can function as an audio book player as well.

    No matter which kind of audio book you prefer to listen to, there is an ever-increasing variety of works that you can select from these days. Virtually any subject matter that is contained in printed books will have at least some audio version available as well. However, books on audio cassettes are starting to become rarer.

    Nola (August 21, 1974 -November 22, 2015) was a northern white rhino(犀牛) who lived at the San Diego Zoo Safari Park near Escondido, California. At her death, she was one of only four remaining northern white rhinos in the world. The other three lived in Kenya. World Rhino Day, held on September 2, is to raise awareness(意识) of the less than 30,000 other rhinos left on Earth.

    “Rhinos need our help today, not tomorrow,” Nola's lead keeper Jane Kennedy said. “Last year we lost over 1,200 rhinos just in South Africa. If we continue to lose more than 1,000 rhinos a year, in 10 to 20 years all the rhinos on the planet will be gone.”

    “Unfortunately, most animals are in danger of dying out because of humans,” Kennedy says.“ Humans have either poached animals, or because there are over seven billion of us, we've taken up too much of the world's resources ”. Poachers illegally hunt rhinos for their horns. They sell the horns for thousands of dollars per pound, to be used for art, jewelry, and decorations. Experts believe that one rhino is poached every eight hours.

    In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell (细胞) samples from more than 8,000 different types of animals, including the northern white rhino. Scientists hope that by studying the rhino cells, they will get greater understanding of it, and will find ways to increase its numbers.

    Jane Kennedy describes World Rhino Day as “a celebration of rhinos along with an awareness campaign for everybody across the world to know that rhinos need our help.” At the San Diego Zoo, children and adults are welcome to visit and speak with zookeepers to learn about rhinos. But you don't have to live in San Diego to celebrate World Rhino Day. It is observed around the world, with zoos and wildlife parks holding special events and programs to teach people about rhinos, and enable them to see the animals up close.
