    Camberwell College Swimming Pools

    Camberwell College of Arts has one 50m (Olympic sized) pool with a depth of 2m throughout, and one 25m pool with a 1m shallow end and a 4m deep end. Both pools may be used by the general public at certain times.

    50m Pool

    The pool is often used for classes, but the general public may use two lanes（泳道）for lane swimming at the following times.

    Monday:        06:30-11:30 and 19:00-21:00

    Tuesday:        06:30-11:30 and 18:00-21:00

    Wednesday:    06:30-13:30 and 17:30-21:30

    Thursday:    06:30-13:30

    Friday:        06:30-13:30

    Weekends:    09:00-17:00

    Children under the age of 14 must be accompanied by an adult.

    Please note that during College holidays, these times will be different. Call 04837 393560 for up-to-date information.

    25m Pool

    The 25m pool is available for recreational (non-lane) swimming from 07:00-09:00 and 12:30-13:30 on weekdays, and 10:00-16:00 on Saturdays.

    Children aged 12 and under must be accompanied.

    We regret that the 25m pool will be closed for redecoration between 21st July and 18th August. The men's changing rooms will be closed for the week beginning 19th August, and the women's changing rooms will be closed the following week. Alternative（可选用的）changing rooms will be made available. We're sorry for this.

    As any plane passenger will confirm, a crying baby is almost impossible to ignore, no matter how hard you try. Now scientists believe they may have worked out why. A baby's cry pulls at the heartstrings(扣人心弦) in a way while other cries don't, researchers found.

    Researchers found that a baby's cry can trigger unique emotional responses in the brain, making it impossible for us to ignore them—whether we are parents or not. Other types of cries, including calls of animals in great pain, fail to get the same response—suggesting the brain is programmed to respond specifically to a baby' cry.

    A team of Oxford University scientists scanned the brains of 28 men and women as they listened to a variety of calls and cries. After 100 milliseconds—roughly the time to blink(眨眼)—two parts of the brain that respond to emotion lit up. Their response to a baby's cry was particularly strong. The response was seen in both men and women—even if they had no children.

    Researcher Dr Christine Parsons said, “You might read that men should just notice a baby and step over it and not see it, but it's not true. There is a special processing in men and women, which makes sense from an evolutionary view that both men and women would be responding to these cries.” The study was in people who were not parents, yet they are all responding at 100ms to these particular cries, so this might be a fundamental response present in all of us regardless of parental status.

    Fellow researcher Katie Young said it may take a bit longer for someone to recognize their own child's cries because they need to do more “fine-grained analysis”. The team had previously found that our reactions speed up when we hear a baby crying. Adults performed better on computer games when they heard the sound of a baby crying than after they heard recordings of adults crying.

    I'm sitting in my kitchen in London, trying to figure out a text message from my brother. He lives in our home country of Germany. We speak German to each other, a language that's rich in odd words, but I've never heard this one before: fremdschämen. I'm too proud to ask him what it means. I know that eventually, I'll get it. Still, it's slightly painful to realize that after years of living abroad, my mother tongue can sometimes feel foreign.

    Most long-term migrants know what it's like to be a slightly rusty(生疏的) native speaker. The process seems obvious: the longer you are away, the more your language suffers. But it's not quite so straightforward.

    In fact, the science of why, when and how we lose our own language is complex and often different to what we think. It turns out that how long you've been away doesn't always matter. Socializing with other native speakers abroad can worsen your own native skills. And emotional factors like trauma(精神创伤) can be the biggest factor of all.

    It's not just long-term migrants who are affected, but to some extent anyone who picks up a second language. The minute you start learning another language, the two systems start to compete with each other, says Monika Schmid, a linguist at the University of Essex.

    Schmid is a leading researcher of language attrition, a growing field of research that looks at what makes us lose our mother tongue. In children, the phenomenon is somewhat easier to explain since their brains are generally more flexible and adaptable. Until the age of about 12, a person's language skills are relatively easy to change. Studies on international adoptees have found that even nine-year-olds can almost completely forget their first language when they are removed from their country of birth.

    But in adults, the first language is unlikely to disappear entirely except in extreme circumstances. For example, Schmid analyzed the German of elderly German-Jewish wartime refugees(难民) in the UK and the US. The main factor that influenced their language skills wasn't how long they had been abroad or how old they were when they left. It was how much trauma they had experienced as victims. Those who left Germany in the early days of Nazi occupation, before the worst violence, tended to speak better German – despite having been abroad the longest. Those who left later, tended to speak German with difficulty or not at all.

    "It seemed very clearly a result of this trauma", says Schmid. "Even though German was the language of childhood, home and family, it was also the language of painful memories." The most traumatised refugees had held them back. As one of them said: I feel that Germany betrayed me. America is my country, and English is my language.

Oxford English Dictionary (OED) announced on November 23 for the first time that it has chosen not to name one single word of the year, but many words for the "special" year 2020. Describing 2020 as "a year which cannot be neatly summarized in one single word". OED said on Monday that there were too many words to sum up the events of 2020. From more than 11 billion words found in web-based news, blogs and other text sources, its lexicographers(词典编纂者)revealed what the dictionary described as "great shifts in language data and frequency rises in new words" over the past 12 months.

Most words of the year are coronavirus-related, including coronavirus, lockdown, circuit-breaker, keyworkers and face masks. The report said the word "coronavirus" dates back to the 1960s and was previously "mainly used by scientific and medical specialists". But by April this year it had become one of the most frequently used nouns in the English language, beyond even the usage of the word "time". It said use of the word "pandemic" has increased by more than 57,000 percent this year.

The revolution in working habits during the pandemic has also affected language, with both "remote" and "remotely" seeing more than 300 percent growth in use since March. "On mute(静音)"and "unmute" have seen 500 percent rises since March, while the words "workation" and "staycation" also increased drastically.

Casper Grathwohl, the president of Oxford Dictionaries, said. "I've never witnessed a year in language like the one we've just had. The Oxford team was identifying hundreds of significant new words and usages as the year unfolded." "2020 has been filled with new words unlike any other," Grathwohl added.

The OED's announcement mirrored the huge influence of the COVID-19 on the people from all walks of life. To bring life back to normal, countries such as Britain, China, Germany, Russia and the United States are racing against time to develop coronavirus vaccines.
