    If a trip to Rome or Paris is in your future, be prepared: The European Union Parliament is calling for an end to visa-free travel Americans. EU lawmakers passed a resolution urging the EU Commission to impose visas on U. S. citizens traveling into the 28-nation bloc.

    The dispute(争论)centers on reciprocal treatment of travelers from EU nations and the United States. While Americans have been able to travel throughout EU member nations without a visa, the U. S. still requires citizens of five EU countries-Bulgaria, Croatia, Cyprus, Poland and Romania-to apply for entry visas when visiting the U. S, Reuters reports. Citizens of the other 23 EU member nations can use the U. S. visa waiver program to enter America. The EU lawmakers are calling for mutual treatment for all EU citizens, says Reuters. They've given the EU Commission two months to respond.

    The trans-Atlantic visa dispute first came to light in April 2014, according to an EU Parliament news release. At that time, five countries-Australia, Brunei, Canada, Japan and the U. S. –required visas for some EU citizens. Since then, Australia, Brunei and Japan have lifted their visa requirements for all EU citizens. Canada, which currently imposes(推行)visa requirements on Bulgarian and Romanian citizens, plans to follow suit in next December, leaving just the United States at odds with the issue of reciprocity of visa-free travel with the EU.

The EU says if a visa requirement for Americans is introduced, it would be temporary, according to a story in Money, which did not give a time frame.

    In January, 2016, Harry Styles made a bold decision. He left the popular boy band One Direction and went solo (单飞). Now he is making his own voice heard. The 23-year-old British singer released his first solo single called Sign of the Times. His self-titled album (个人同名专辑) is coming out on May 12.

    Going solo is a journey for him to find his identity (身份). Though at the time, he was uncertain about his future, he kept a word in his mind - “honesty”. “I didn't want to write ‘stories',” he told Rolling Stone. “I wanted to write my stories, things that happened to me. The number-one thing was I wanted to be honest. I hadn't done that before.”

    He is indeed full of stories since beginning his solo career. Last fall, he spent two months recording on a remote island in Jamaica (牙买加).Along with some musicians, he filled a two-floor house with instruments. They hung out at the bar that looked like a tree house. Many mornings began with a swim in the river down the hill. They watched many romantic comedies. Styles always held a black notebook and looked like a college student who was studying, Rolling Stone reported.

    His coming album is about rock music. In fact, he grew up with it. His father Desmond was a rock music fan. When Styles was very young, he danced to The Dark Side of the Moon, a classic song by British rock band Pink Floyd. “I couldn't really get it. But I just remember (thinking that) this is really cool.”

    Harry said, “At the very beginning, all I wanted was to be the granddad with the best stories.” Surely, now he is on the right track (轨道).

    Reports tell us that Americans work more and vacation less than people in other major industrial countries. Still, millions of Americans do try to get away from home for a week or two in the summer months. Some might even have the time and money to spend longer on vacation.

    For example, many retired Americans can be found driving around the United States in big recreational vehicles, known as R. V.'s. These serve as a home away from home. In fact, it might even be their only home as they see the country.

    Some American families get in their cars and drive to historic places like Colonial Williamsburg in Virginia. There, they can experience what life was like for early Americans. If that is not exciting enough, also in Williamsburg is a water park and an amusement park with rides.

    Other Americans visit national parks like Yellowstone or Yosemite out in the West. They want to spend time with nature. Or they take their vacation by a lake or the ocean. They might swim or fish. But many just want to sit and enjoy the feeling of doing nothing, except maybe read a book.

    Some families fly to other countries on vacation. Or they go on a cruise ship (大型游轮) and stop in different ports. Cruise ships are like floating cities.

    But not everyone goes someplace special on vacation. This might be the only time for people to work on things like home improvement projects. And while they do that, they might think of all the fun their friends are having.

    In 1977, a dead author of detective stories saved the life of a 19-month-old baby in a most unusual way. The author was Agatha Christie, one of the most successful writers of detective stories in the world.

    In June 1977, a baby girl became seriously ill in Qatar, near Saudi Arabia. Doctors were unable to find out the cause of her illness with confidence, so she was sent to Hammersmith Hospital in London. She was then only semi-conscious and on the "Dangerously Ill" list. A team of doctors hurried to examine the baby only to discover that they, too, were confused by the very unusual symptoms (症状). While they were discussing the baby's case, a nurse asked to speak to them.

    "Excuse me," said Nurse Marsha Maitlan, "but I think the baby is suffering from thallium (铊) poisoning(中毒)."

    "What makes you think that?" Dr. Brown asked. "Thallium poisoning is extremely rare."

    "A few days ago, I was reading a novel called A Pale Horse by Agatha Christie," Nurse Maitlan explained. "In the book, somebody uses thallium poison, and all the symptoms are described. They're exactly the same as the baby's."

    "You're very thoughtful and you may be right," another doctor said. "We'll carry out some tests and find out whether it's thallium or not."

    Tests showed that the baby had indeed been poisoned by thallium, a rare metallic substance(物质) used in making special glass. Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back to Qatar. Later it was reported that the poison might have come from an insecticide (杀虫剂) used in Qatar.
