The bed should be reserved as a place for sleep, but people tend to read an iPad a lot in bed before they go to sleep.

    Charles Czeisler, a professor at Harvard Medical School, and his colleagues got a small group of people for an experiment. For five days in a row, the people read either a paper book or an iPad for four hours before sleep. Their sleep patterns were monitored all night. Before and after each trial period, the people took hourly blood tests to paint a day-long picture of just how much melatonin (褪黑激素) was in their blood at any given time.

    When subjects read on the iPad as compared to the paper books, they reported feeling less sleepy at night and less active the following morning. People also took longer to fall asleep on the iPad nights, and the blood tests showed that their melatonin secretion (分泌) was delayed by an hour and a half.

    The researchers conclude in today's journal article that given the rise of e-readers and the increasingly widespread use of e-things among children and adolescents, more research into the long-term consequences of these devices on health and safety is urgently needed. Czeisler and colleagues go on, in the research paper, to note：“Reading an iPad in bed may increase cancer risk.”

    However, software has been developed that can reduce some of the blue light from the screens of phones and computers according to time of day, and there are also glasses that are made to filter (过滤) short wavelengths. While they seem like a logical solution for the nighttime tech users, it needs more research.

    Housework is a frequent source of disputes (争论) between lazy husbands and their hard-working wives, but women have been warned not to expect men to pull their weight any time soon.

    A study from Oxford University has found that men are unlikely to be doing an equal share of housework before 2050. Mothers, the researchers warned, will continue to shoulder the burden of childcare and housework for the next four decades, largely because housework such as cleaning and cooking is still regarded as“women's work”.

    The gap between the amount of time men and women spend on housework has narrowed slowly over the past 40 years. But it will take another four decades before true housework equality is achieved, the study concluded. The research found that in the Nordic countries, the burden of housework is shared more equally between men and women. In the UK, women spend an average of four hours and forty minutes each day on housework, compared with two hours and twenty-eight minutes for men. This is an improvement from the 1960s, when British women typically spent six hours a day on housework, while men spent just 90 minutes every day.

    But progress towards housework equality appears to be slowing in some countries. Dr Oriel Sullivan, a research reader from Oxford's Department of Sociology, said, “we've looked at what is affecting the equality in the home, and we have found that certain tasks seem to be given according to whether they are viewed as ‘men's work' or ‘women's work'.”Dr Sullivan said cultural attitudes taught at school may be responsible for the views of housework. “At school it is much easier for a girl to be a tomboy, but it is much more difficult for a boy to enjoy baking and dancing,” she said.

    Some international languages are widely used for many purposes. Some minority languages will die out and some nations tend to keep minority languages. I reckon that most common used international languages ease our life quality and communication with different nationalities. On the other hand, we need to help improve minority languages.

    There are many languages in the entire world but two or three minority languages die out each year. Some countries try to save dying languages. For instance, Australian Government created a project to save the language and culture of Maori who are Australian aborigines. And there are other projects to keep minority languages such as American Indian language.

    However, the worldwide job market usually requires candidates who can speak English or other international languages. People who cannot speak lingua franca (共通语) could hardly be promoted at work. For example, some companies need an employee who can deal with foreign companies. So most people tend to learn at least one international language that helps them to find a better job.

    Therefore, world needs one common lingua franca that should be spoken in any country. Consequently, one common language should be a required subject in every school. So anyone speaking one common language can travel without worries to any point of the world and trade their products. People will not be forced to learn many languages.

    In conclusion, we should help minority nations to keep their languages for the cultural diversity. To ease the worldwide communication among nations, we should create a common language and provide courses of it. As a result, no one will face a language issue.

    A mystery surrounds my grandmother's collection of salt cellars (盐瓶). No one in the family seems to know when she started collecting them, or exactly how many she had.

    My grandmother died just over two years ago. At 91, she had spent 30 years without her right leg, which was removed due to cancer the year I was born. She was a poet, an artist, a food lover and a salt cellar collector. The funny thing about the salts, as she called them — I never once heard her say salt cellar — was that although everybody knew they were her hobby and everyone was always searching for them at yard sales or in stores, nobody seemed to know what they meant to her and they just wanted to make her happy. Grandma kept her salts in a dark wooden corner display case in the living room. Since her death the case has remained exactly as she left it. Grandpa tries his best to preserve his memories of her just as they are.

    Now I am collecting, too. Collecting memories about my grandmother's hobby, a way she spent her time. And as I hold one of them in my hand, I picture her holding it in her hand on the day she got it. She is smiling. My mother and her two sisters all have small collections, but my mother admits that she was more interested in finding salts to send to Grandma.

    Grandma once wrote a poem titled “When April Comes”. The poem contains the line, “When April comes and I am not around, remember me when daffodils are found.” Now, Grandpa is working on a poem with the line, “April came and you were not around”.

    But she was, somehow. She was there in the memories left behind by her possessions.

    Thirteen hours later we just arrived in Paris after many dramas (戏剧性事件).

    I rented a car, filled it up and moved ahead to Bristol airport that morning. We set off at 8:00 a.m. and all was going well until we got to the turn for Bristol airport. The airport sign (指示牌) suggested we went out from the M5, but Suri asked me to continue going straight ahead, so against my better judgment, I let the airport turn pass us by.

    Next we left for South Wales, the car was back and we had a plane to Paris to catch in a couple of hours. It was about then that I realized we were heading for Wales on a six­road highway. I felt very bad. We turned off the highway and turned into a country road, as directed by Suri and there was a sign saying that the road to the airport was closed. I saw a lady watering her garden and asked her about the best way to the airport. She said we were at least 30 minutes from the airport, but she couldn't help us with the right directions (方向).

    I was so worried as we really were out in the country without any guidance. All I could think of was to turn Suri off and follow the signs myself.

    Then finally after many butterflies in the stomach and feeling like my heart was going to burst (爆裂) out of my chest, there was a proper green sign to the airport and we followed it with so much joy.

    Driving from the airport into Paris was a shock, Lots of homeless people were sleeping under the highways with rubbish everywhere.

Anyway we're now in Paris. The experience of getting lost is now almost laughable. In another 24 hours will be my 50th birthday. I have a big party planned for myself in Paris.
