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.

A. can’t be reused

C. are a waste of money

D. are as bad as paper bags

In choosing a friend, one should be very careful. A good friend can help you study. You can have fun together and make each other happy. Sometimes you will meet fair?weather friends. They will be with you as long as you have money or luck，but when you are down, they will run away. How do I know when I have found a good friend? I look for certain qualities of character，especially understanding, honesty and reliability(信任)．

Above all else, I look for understanding in a friend. A good friend tries to understand how another person is feeling. He is not quick to judge. Instead, he tries to learn from others. He puts himself in the other person’s place, and he tries to think of ways to be helpful. He is also a good listener.

At the same time, however, a good friend is honest. He does not look for faults in others. He notices their good points. In short, a friend will try to understand me and accept me.

Another quality of a friend is reliability. I can always depend on a good friend. If he tells me he will meet me somewhere at a certain time, I can be sure that he will be there. If I need a favor，he will do his best to help me. If I am in trouble, he will not run away from me.

There is a fourth quality that makes a friend special. A special friend is someone with whom we can have fun. We should enjoy our lives, and we would enjoy our friendship. That is why I especially like friends who are fun to be with. A good friend likes the same things I like. We share experience and learn from each other. A good friend has a good sense of humor too. He likes to laugh with me. That is how we share in the joy of being friends. And I know that he is looking for the same quality in me.

When I meet someone who is reliable, honest, and understanding，I know I’ve found a friend!

As the father of a student, I have experienced first hand what a great teacher is. My son was in the 4th grade last year, and he had a teacher called Miss Green. I believe that when he is an adult he will surely look back on her as the best teacher he has ever had.

My son has attention deficit disorder(注意力缺损症) that makes it a little more difficult for him to learn.She was able to change her teaching methods for him so that he could keep up with the rest of the class. As a result, he got straight As on many subjects. She regarded her class as a family and they even had their own class song. She would often have them sing it to encourage them and develop a team spirit for them. When she saw that they were no longer listening carefully to what she was teaching, she would have them close their textbooks, stand up all around the room and throw around a small football. This helped them clear their minds and then focus_on the lesson again.Besides, she was quick to reply to any phone calls or emails from us and got rid of our worries about children quickly.

When my son went to the 5th grade this year, we happened to pass her classroom.When she saw my son, her face lit up and she came out and hugged him.She generally loves all of the children in her classroom and that love really shows.I can only pray that my son will continue to get teachers just like her for the rest of his school years.

Artificial intelligence,or AI,has been applied in a wide range of fields to perform specific tasks,including education,finance,heavy industry,transportation,and so on.

Education

There are a number of companies that create robots to teach subjects to children ranging from biology to computer science,though such tools have not become widespread yet.Advancements in natural language processing, combined with machine learning,have also enabled automatic grading of assignments.AI has also led to an explosion in popularity of MOOCs,or Massive Open Online Courses,which allows students from around the world to take classes online.

Finance

Use of AI in banking can be tracked back to 1987.Banks use artificial intelligence systems to organize operations,maintain book-keeping,invest in stocks,and manage properties.Also,systems are being developed,like Arria,to translate complex data into simple and personable language.There are also wallets,like Wallet AI,which monitor an individual's spending habits and provides ways to improve them.

Heavy industry

Robots have become common in many industries and are often given jobs that are considered dangerous to humans.Robots have proven effective in jobs that are very repetitive which may lead to mistakes or accidents due to failure in concentration and other jobs which humans may find degrading.

Transportation

Today's cars can have AI-based driver assist features such as self-parking and advanced cruise controls.AI in transportation is expected to provide safe,efficient,and reliable transportation while minimizing the impact on the environment and communities.

Toys and games

Companies like Mattel have been creating AI-enabled toys for kids as young as age three.Using proprietary AI engines and speech recognition tools,they are able to understand conversations,give intelligent responses and learn quickly.AI has also been applied to video games,for example video game bots,which are designed to stand in as opponents where humans aren't available or desired.

When I was a boy we used to live across the road from a big hill with huge oak trees growing out of it.When winter arrived,thick,heavy snow would fall,and my two brothers would grab their sleds heading over to the hill for a day of fun.I remember watching them with envy because I was still too small to go sledding.Finally,one winter I was considered big enough and joined my brothers as they carried their sleds up the long hill and prepared to ride down it.

The first few trips I rode with one of my brothers and had the time of my life.It was so exhilarating when the wind whipped across my face as I flew down the hillside on the wooden sled.Near the end of the day I was overjoyed too when my oldest brother decided to let me try riding the sled all by myself.I climbed on it full of excitement and lay on my stomach.Then with one big push my brother sent me down the snowy hillside.I was doing pretty well too until I hit an old stump hidden by the snow and went off course,straight towards one of those big oak trees.My heart pounded in my chest and I could hear myself screaming.At the last possible second I rolled off and the sled crashed into the tree.I could hear my brothers running down the hill yelling,“You have to steer（操控）! You have to steer!”

Sadly,that wasn’t the last time I failed to steer when some obstacle knocked me off course in my life.Many times problems,troubles,and my own failures have sent me crashing into the trees of anger,frustration,and despair.I am still learning that life isn’t always safe sledding.I am sti l learning that it is up to me to steer myself back to love,back to kindness,back to goodness,and back to God.

Life is a trip,but no one ever said it was a smooth ride.Steer well then.Steer straight.Steer your soul towards the light and the love we are all meant for.
