Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease．But there is another factor that can cause your heart problems more immediately: the air you breathe.

    Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses(分析) now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure．In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely（可能的） to suffer a heart attack within days of exposure than those with lower exposure．A separate study of stroke patients showed that even air that the U．S．Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

    The authors of both studies stress（强调）that these risks are relatively（相对的）small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure．However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices．So stricter regulation（规章制度）by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

    Parents who help their children with homework may actually be bringing down their school grades. Other forms of parental involvement, including volunteering at school and observing a child's class, also fail to help, according to the most recent study on the topic.

    The findings challenge a key principle of modern parenting where schools expect them to act as partners in their children's education. Previous generations concentrated on getting children to school on time, fed, dressed and ready to learn.

    Keith Robinson, the author of the study, said, "I really don't know if the public is ready for this but there are some ways parents can be involved in their kids' education that leads to declines in their academic performance. One of the things that was consistently negative was their parents' help with homework." Robinson suggested that may be because parents themselves struggle to understand the tasks."They may either not remember the material their kids are studying now, or in some cases never learnt it themselves, but they're still offering advice.

    Robinson assessed parental involvement performance and found one of the most damaging things a parent could do was to punish their children for poor marks. In general, about 20% of parental involvement was positive, about 45% negative and the rest statistically insignificant.

    Common sense suggests it was a good thing for parents to get involved because "children with good academic success do have involved parents", admitted Robinson. But he argued that this did not prove parental involvement was the root cause of that success. "A big surprise was that Asian-American parents whose kids are doing so well in school hardly involved. They took a more reasonable approach, conveying to their children how success at school could improve their lives."

    Girls who lack confidence in school have a new champion. She is only 10 years old. Alice Tapper, a fifth - grader says, that her goal is to encourage girls of all ages to “be more confident in raising their hands”. Alice cared so much about the issue (问题) that she helped create a Girl Scout badge (徽章).

    The pink badge—Alice chose her favorite color—shows three hands reaching for the sky. It says, “Be brave. Raise your hand.”

    Alice's idea came during a fourth - grade field trip to Jamestown, Virginia. She found that boys raised their hands to answer questions even though they weren't sure of the answers. The girls just listened quietly.

    “Girls are afraid to raise their hands because they get shy. They have to be 90 percent sure, while boys just raise their hands and say, 'I know it,'” Alice said during a recent interview. She added that girls should have confidence, step up, and become leaders by raising their hands for women are equal to men.

    Alice's “Raise Your Hand” badge has become wildly popular, and not just in the United States. “People in Japan and China want to use the badge,” she said. “We sold out the badge quickly, but we're making more.”

    Alice wants to be a teacher when she grows up. But first, she wants to see a revolution in confidence for girls of all ages. She knows that won't happen overnight. “ It takes time,” Alice said, “but I can speed up the process.”

    We've all had cases where we've waited just a bit too long to pay an electric bill or speeding ticket. But one man, from California by reasonable assumption, who goes by “Dave”, recently took procrastination (拖延) one step further, by paying a parking ticket almost a half-century after it was given.

    In December 2018, the Minersville Police Department in Pennsylvania received a letter in the mail. Whoever wrote the letter decided it was best to keep his name somewhat unknown, so he put the return address as “Wayward Road, Anytown California” under the name “Feeling guilty”.

    When the officers opened the envelope, they found a brief letter, along with a $5 bill, and a parking ticket dating all the way back to 1974.The note read, “Dear PD, I've been carrying this ticket around for 40 plus years always intending to pay. Forgive me if I don't give you my info. With respect, Dave.”

    Even though the initial parking ticket was only for $2, “Dave” must have felt awfully guilty because he left 150 percent, or $3, in interest.

    Michael Combs, the Police Chief of the Minersville Police Department, stated in an interview that the same ticket would cost about $20 if it was given today. Combs went on to share that the original ticket from 1974 was given to a vehicle that had an Ohio license plate.

    Because there was no system for tracking tickets given to out-of-state cars back then, “Dave” could have gotten away with never paying the $2 fine. But apparently, guilt got the best of him, and he decided to finally cough up the money more than 40 years past its due date.

    In the near future, daily newspapers and monthly magazines will probably disappear. Electronic media（媒体） can provide the same information faster and cheaper. The Internet, together with laptops and mobile phones, makes it possible that almost everyone can at any time and in almost any place get some news for free or for few fees.

    You'll browse the computer newspapers or magazines just like turning on TV. An electronic voice will tell you stories about the latest events. You'll even get to choose the kind of voice you want to hear. Want more information on the brief story？ A simple touch makes the whole text appear.

    There are the predictions from the experts working on the newspapers of the future. Imagined as part of home media and entertainment systems, computer newspapers and magazines would unite printed and broadcast news, offering information and analyzing video images of news events.

    The continuing loss of readers will lead to a small number of advertisements in newspapers. It makes no sense to spend millions of dollars to print ads.

    With the development of technology, more and more electronic media have been created until now, but replacing the traditional newspapers and magazines has a long way to go, because the resistance to computer newspapers and magazines from journalism（新闻业） may be much stronger. Since it is such a cultural change, it may be not until the present journalists（新闻工作者）, who aren't used to it, die off that the newspaper industry is not considered as an industry any longer. Anyway, technology is making the traditional newspapers and magazines disappear gradually.

The success of The Pickwick Papers made Dickens very popular. He suddenly found himself at twenty-four the most famous novelist of his day. Busy as his social life was, he worked on two novels at the same time—Oliver Twist and The Pickwick Papers. He was particularly proud of The Pickwick Papers, which was a huge success and was regarded as a comedy (喜剧) masterpiece (杰作). "If I were to live a hundred years and write novels in each, I should never be so proud of any of them as I am proud of The Pickwick Papers," he said.

It has been said of Dickens that he grasped (抓住) the imagination of his readers because his imagination grasped himself. The people in his works were so real that they could make him laugh or cry. When writing Oliver Twist he said that he could not rest until Fagin, the wrongdoer (做坏事的人), had been hanged.

Dickens' marriage to Catherine Hagarth, with whom he had ten children, ended unhappily in 1858. He started to travel about giving readings of his works. His interest in theater gave his novels the qualities that made them suitable for reading aloud on the stage. A tiring travel to the United States affected his health. On June 9, 1870, when he was working on a new novel, he died, as he had wished. He said he wanted to die working.
