As we recently discovered，there is a Stepmother’s Day，though it is not on any official holiday calendar.So，it would be safe to assume that there is a similar day for stepdads，too.

Right? Well，it depends on what you read.A Google search brought up posts that say，for example，“It’s on father’s day--father’s day is for fathers，step—fathers and people who are like fathers to you-it’s a day for making father figures feel special.”Further searching found a Stepfather’s Day

Facebook page that says，“The unofficial Stepfather’s Day is the fourth Sunday of June.”

Unfortunately，as of the publishing of this article，only 30 people have “liked” the page.Considering that studies show 3.3 million men，or 11.1%of U.S.fathers，live with at least one stepchild，that’s only a drop in the ocean.

It’s interesting to note that there is a National Grandparents’ Day.President Jimmy Carter signed it into law in 1978.Law! While grandparents are undoubtedly special people in our children’s lives，they are often seen as the most loving family members.But what about the stepparents? The stepparents are the ones who are often the outsiders，the ones who have to endure the hurtful “You’re not my dad!” or “You’re not my mom!” And yet they never give up.

They do their best to overcome the inherent challenges of stepparents and be role models for their stepchildren.These unsung(未被颂扬的)family heroes deserve “official” days of honor.Perhaps if we are loud enough，President Obama，who had a stepfather himself，will sign into law National

Stepmother’s Day and National Stepfather’s Day.

Are you with me? Follow me and get your voice heard.How cool it would be if we could make this happen!What is the reason for setting an official holiday for stepparents?

9.If you want to stay young, sit down and have a good think. This is the research result of ProfessorFaulkner,who says that most of our brains are not getting enough exercise and as a result, we areageing unnecessarily soon.Professor Faulkner wanted to find out why healthy farmers in northern Japan appeared to be losingtheir ability to think and to reason at a relatively early age, and how the process of ageing could beslowed down.He set about measuring brain volumes of a thousand people of different ages and occupations.Computer technology enabled him to obtain precise measurements of the volume of the front andside sections of the brain, which relate to intelligence and emotion, and determine the humancharacter.Contraction of front and side parts—as cells die off—was observed in some subjects in their thirties,but it was still not evident in some sixty?and seventy?year?olds.Faulkner concluded from his tests that there is a simple way to slow the contraction—using thehead.The findings show that contraction of the brain begins sooner in people in the country than in thetowns.Those least at risk, says Faulkner,are lawyers,followed by university professors and doctors.White?collar workers doing routine work are,however, as likely to have shrinking brains as the farmworker, bus driver and shop assistant.Faulkner’s findings show that thinking can prevent the brain from shrinking. Blood must circulateproperly in the head to supply the fresh oxygen the brain cells need.“The best way to maintaingood blood circulation is through using the brain,”he says.“Think hard and engage inconversation.Don’t rely on pocket calculators.”Professor Faulkner wanted to find out__________.

18.“If there is one thing I’m sure about, it is that in a hundred years from now we will still be reading newspapers．It is not that newspapers are a necessity．Even now some people get most of their news from television or radio．Many buy a paper only on Saturday or Sunday．But for most people reading a newspaper has become a habit passed down from generation to generation． The nature of what is news may change．What basically makes news is what affects our lives — the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same．I think there will be more coverage of scientific research, though．It’s already happening in areas that may directly affect our lives, like genetic(基因) engineering．In the future, I think there will be more coverage of scientific explanations of why we feel as we do — as we develop a better understanding of how the brain operates and what our feelings really are． It’s quite possible that in the next century newspapers will be transmitted(传送) electronically from Fleet Street and printed out in our own home．In fact, I’m pretty sure that how it will happen in the future．You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read — sports and international news, et C． I think people have got it wrong when they talk about competition between the different media(媒体)．They actually feed off each other．Some people once foresaw that television would kill off newspapers, but that hasn’t happene D．What is read on the printed page lasts longer than pictures on a screen or sound lost in the air．And as for the Internet, it’s never really pleasant to read something just on a screen．[单选题] From the passage, we can infer _______．
