This Monday, the nation will start to celebrate Presidents' Day, just seven days before George Washington's birthday. Everyone agrees that day is a holiday. but is it just to celebrate George Washington's Birthday? What about Abraham Lincoln? Some government offices call it Presidents' Day. Others say the holiday is officially Washington's Birthday. Confused yet?

    George Washington was elected the country's first President on April 30,1789. Soon after, Americans began publicly celebrating his birthday. Presidential historians say the actual date of George Washington's birth is February 11,1732. But a change inthe calendar system 20 years later shifted all dates, making Washington's birthday February 22, which is now well accepted. In 1879. Congress made Washington's birthday an official federal holiday. It was the first federal holiday to celebrate an individual's birthday. In 1968, Congress passed the Monday Holidays Act, which moved the holiday to the third Monday in February. The new law did not change the holiday's name. It was still called Washington's Birthday, even though some law makers wanted to call it Presidents' Day to include Abraham Lincoln, whose actual birthday is February 12.

    Many people argue that the holiday should celebrate all past Presidents. They feel Lincoln should be honored for his role in preserving the nation during the Civil War and helping to free slaves. Others feelthe holiday should only honor Washington. the country's first President. They say shifting the focus away from Washington would mean future generations of kids would not know about the Father of Our Country.

    Laws have been introduced in Congress over the years to requireuse of the term “George Washington's Birthday.”but none of those laws have been passed. Meanwhile, many stategovernments and school districts now use the term “Presidents' Day．”Many stoles also use it to promote holiday sales.

    Should the holiday honor Washington, Washington and Lincoln, or all past Presidents? Write to emailbag@timeforkids, com and tell us what you think.

    Outside her shabby cottage, old Mrs. Tailor was hanging out laundry on a wire line, unaware that some children lay hidden in the leaves of a nearby tree watching her every move. They were determined to find out if she really was a witch.

    They watched as she took a broomstick to clean the dirt from her stone steps. But, much to their disappointment, she did not mount the broomstick and take flight. Suddenly, the old lady's work was interrupted by the cackling of her hen-a signal that an egg had been laid in the warm nest on top of the haystack.

    The old broomstick was put aside as she hobbled off towards the haystack followed by Sooty, a black cat she had rescued from a fox trap some time back. With only three legs, it was hard for Sooty to keep up with the old lady. The cat provided proof-the children were sure that only a witch could own a black cat with three legs.

    There, standing on a wooden box, was Mrs. Tailor, stretching out to gather her precious egg. Taking the egg in one of her hands, she began to climb down when, without warning, the box broke and the old lady fell.

    "We have to got and help her," whispered Amy.

    "What if it is a trick?" replied Ben.

    "Don't be silly, Ben. If she were a witch, she would have turned us into frogs already," reasoned Meg. "Come on Amy, let's go." The girls climbed down the tree and ran all the way to the haystack.

    Approaching carefully, they could see a wound on the old lady's face. She had knocked her head on a stone and her ankle was definitely broken. "Go and get Dad," Amy yelled to her brother. "Tell him about the accident."

    The boys did not need another excuse to leave. They ran as fast as they could for help, hoping that Mrs. Tailor would not wake and turn the girls into frogs.

    When Kate's paintings were on show in London，a poet described her paintings as “a ribbon (丝带）around a bomb”．Such comments seem to suggest Kate had a big influence on the art world of her time．Sadly，she is actually a much bigger name today than she was during her time．

    Born in 1907 in a village near Mexico City，Kate suffered from polio（小儿麻痹症）at the age of seven．Her spine (脊柱)became bent as she grew older．Then，in 1925，her back was broken in several places in a school-bus accident．Throughout the rest of her life，the artist had many operations，but nothing was able to cure the terrible pain in her back．However，the accident had an unexpected side effect．While lying in her bed recovering，Kate taught herself to paint．

    In 1929，she got married to Diego Rivera，another famous Mexican artist．Rivera's strong influences on Kate's style can be seen in her early works，but her later works from the 1940s，known today as her best works，show less influence from her husband．

    Unfortunately，her works did not attract much attention in the 1930s and1940s，even in her home country．Her first one-woman show in Mexico was not held until 1953．For more than a decade after her death in 1954，Kate's works remained largely unnoticed by the world，but in the 1970s her works began to gain international fame at last．

    In England, some food companies across the whole country have been told to carry out urgent (紧急的) tests on all beef products. Do you know why? That's because some food companies used horse meat to make beef products.

    There are some examples about the horse meat matter. In January, 2013, in a number of UK supermarkets, frozen hamburgers were found to have traces of horse meat in them. Some frozen beef products made by food company FINDUS were found to contain horse meat. All of the beef products made by this company have been removed from sale.

    The government said that there's nothing to suggest any health risk from the products. Food minister David Heath said people should not throw away frozen meat products and carry on eating meat. The government will tell people not to eat meat if the meat is not safe.

    Food safety has been an important matter all over the world. More and more countries plan to take some useful measures to ensure the safety of food.

When I first heard about the improv(即兴表演) classes, I was torn. As an introvert, I feared getting on stage and improvising in front of strangers. However, I knew I wanted to work as a science communicator after finishing my Ph.D. , so it seemed like the perfect opportunity to improve my speaking ability and gain confidence thinking on my feet.

During our first class, we learned a core concept of improv: "yes, and." It means that, as improvisers, we accept what fellow performers say. If someone says that rhinos(犀牛) are librarians, for example, then rhinos are librarians. We do not question the logic; we say "yes" and continue with the scene as if no him is wrong.

I got a taste of how difficult that was when acting out my first scene. My classmate turned to me and said, "Mom is going to be so mad." Mad about what? My mind spun out ideas, and my inner critic shot them all down. We broke the car? No, that's too easy. We failed a test? No, you don't want your classmates thinking you're stupid on the first day. I finally landed on an answer: "Yes, we're going to be late for dinner." The scene proceeded from there, and we eventually finished as two sisters who lost their way on a hiking trail.

The first few scenes were hard, but as weeks turned into months, I became more comfortable thinking on my feet and even started to enjoy our classes. I never silenced my inner critic entirely, but over time, I didn't police my words with quite so much effort. I also became better at listening, relating to my conversation partners, and communicating clearly in the moment.

That training proved useful 6 months ago, when my experiments generated unreasonable data. Early on in graduate school, I would get stuck when this happened; my inner critic would assume I had made a mistake. But then, after embracing the "yes, and" concept, instead of getting discouraged, I kept exploring the data and ended up identifying a new type of cell—one that wasn't behaving as expected. If I hadn't accepted the possibility that the results were real, I would have missed out on the most exciting finding of my Ph.D. so far.

All scientists can benefit from this lesson. If the data say rhinos are librarians, then it's worth investigating whether rhinos are, in fact, librarians. Our job as scientists isn't to generate data that support a preconceived(预想的) story. Our job is to say "yes, and."

In 2017, I was diagnosed (诊断) with Type 1 diabetes (糖尿病). And then I was told that I couldn't drive for a few weeks until my blood sugar levels had1 . 

Driving was a2 very soon after diagnosis for me. I needed to get to the chemist's shop for my diabetes medicine and get to hospital appointments, but at first couldn't, for having been told not to drive. I didn't want to be a3 , having to ask for lifts all the time. 

I found it really4 to be unable to drive, but things settled down after that and seemed to be5 for a while. 6 , to my surprise, I had severe hypoglycemia (低血糖) last year and wasn't able to7 it myself. I called an ambulance and was taken to8 , where I saw doctors and nurses I didn't know as none of them were connected to the diabetes team who usually cared for me. That's where my9 began. They advised me not to drive on the basis of this disease. They told me to call the Driver and Vehicle Licencing Agency (DVLA) and10 what they'd told me to them. This led to my licence being canceled. 

I couldn't11 all that had happened. It seemed12 . I needed answers and13 , so I phoned the Diabetes UK Helpline number I got from their website. They14 I was right in thinking that the DVLA shouldn't have15 my licence based on this hypoglycemia, according to the law. With their help, the DVLA sent me a letter admitting making a mistake. I got it back in six weeks.
