In Britain, it's bottoms up from the week before Christmas till the last firework explodes in the sky announcing the new year. The last Friday before Christmas, popularly known as ‘Mad Friday', is one of the busiest periods for the country's pubs and clubs.

    But it's not just the bars that get busy. Ambulances and A&E departments around Britain get packed out too. Head injuries, cuts, falls…it's easy to end up hurting yourself or others when self-control disappear and your head is spinning due to alcohol revelers have been warned by the health authorities about the dangers of deadly drinking but drinking crazily seems to be part of the festivities for some.

    The charity Alcohol Concern is running a campaign of restriction by encouraging people to have a dry January.

    Jackie Ballard, the charity's Chief Executive, believes the campaign has been successful in recent years. She says, “More than two-thirds of people even six months later are drinking at reduced levels having had amonth off drink. But also a study has shown the impact it has on people's health reducing their blood pressure and blood sugar levels.”

    The study by the University of Sussex followed up nearly 900 participants in Alcohol Concern's Dry January campaign and found out that 72％ of them hadkept harmful drinking sessions down and 4％ were still not drinking.

    Moderation (适度) seems to bethe key to everything. The official recommendation for women is not to regularly drink more than 2 to 3 units of alcohol a day. The limit for men is 3to 4 units of alcohol — no more than a pint of 5.2％ ABV lager, beer or cider.

    Astronomy (天文学) is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about heavens(天堂). But the six planets that he could see with his eyes alone limited man.

    The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.

    Each new tool added to the field of astronomy helped man reach out into space. Until there were telescopes(望远镜), man did not know much about the moon. He did not know that the planet called Saturn(土星) had rings around it. His sight was so limited that he could not see all the planets. In the early 1700s, people thought there were only six planets. Pluto (冥王星), the last of the nine planets to be discovered was seen until 1930.

    Before the spectroscopes (分光镜), man didn't know what kind of gas was in the sun or other stars, without radio telescopes(射电望远镜), we did not know that radio noise came from far in space.

    Today, astronomy is a growing science. We have learned more in the past fifty years than in the whole history of astronomy.

    Most dictionaries will tell you a number of things about a language. There are three important things. These three things are spelling, pronunciation(发音) and meaning.

    First, a dictionary will tell you the spelling of a word. If you are not sure about the spelling of a word, you can try to find the correct spelling in a dictionary. Words are listed in an alphabetical (字母表的) order —— a, b, c and so on. For example, on a dictionary page the "poor" comes before "poverty" and the word "poverty" comes before the "power".

    The words are always given in alphabetical order. The second thing, a dictionary will tell you the pronunciation. Most dictionaries give phonetic, or sound alphabet. The phonetic alphabet (音标) shows pronunciation. The third thing, a dictionary will tell you the meaning of words. You can look up a word and find out what it means. Many words have more than one meaning, and a good dictionary will tell you all of the word's meanings. For example, in English the common word "get" has over 20 different meanings.

    How a few members of the animal kingdom handle the transition to adulthood?

    African elephants

These beautiful beasts come close to imitate teen rebellion. Calves spend a decade with their mothers in female-dominated groups —- and ladies stay there —- but adolescent boys leave mom for noisy crews of bros. In their 20s, they often downsize to smaller male groups.

    Orangutans (猩猩)

Slow metabolism allows these primates to survive food shortages —- times when weather makes ripe fruit scarce. But energy efficiency comes at a cost; growth and maturation take time. Orangutan mamas nurse their young longer than any other wild creature does.

    Orcas(逆戟鲸)

    Killer whales join their mother's familial group for life. This lasting-relationship seems to increase a pup's chance of survival; if mom dies  a young male (under 30) is three times more likely to die than a peer whose mother is alive. Risk of death post-mom-mortem rises as kids get older.

Harp seals

A harp seal's "childhood" lasts just 12 days. A pup's sole purpose during that brief period of coddling(宠爱) is to constantly nurse, gaining a fifth of its birth weight in blubber(鲸脂) every day. Once it's fat —- they become greater from 25 to 80 pounds —- it slides off the ice and takes on the sea.

    Wolf spiders

    Every parent knows that tired toddlers love to hitch a piggyback ride. The wolf spider straps all her babies (40 or 50, on average) onto her back at once, carrying the brood until they are capable of fully functional spider-hood. But luckily she only has to pull them for a few days.
