Q: Article: This is a list of the origins of some slang words or phrases that we all use regularly.These words are common in almost all English speaking nations. Cool Who hasn't used this word at least once in their life when speaking highly of something? This meaning of the word is ly new in English,but not as new as you might think.The earliest record found so far is from 1884 in the phrase"Dat's cool!" Kick the Bucket This means"to die".Many people consider the term to have come from a guilty man standing on an upturned bucket which was then kicked out from under his feet leaving him to hang,but there is no written evidence that this is the case.In fact,it is more likely from a different type of bucket entirely.In butchery ,when a pig was killed it would be hung from a pole.It is mostly likely that in his death throes ,the pig's feet would bang against the rail to which they were tied.Therefore,kicking the bucket was a term referring to the last actions of the pig before he finally died. Bob's Your Uncle Bob's your uncle generally means that something is simple or easy or a"job done".It is most likely that this phrase came about as a result of nepotism .In the late 1800s, Lord Salisbury(first name Robert)was prime-minister of Great Britain.After his third term he was _ by his nephew Arthur.Arthur had been made Chief Secretary of Ireland in 1886. Suspicions arose that Robert was favoring his nephew Arthur.The term"Bob's your uncle"could be used at the time as a reference to this charge of nepotism.

Q: Article: Liu Jiaoyang,16,carefully winds a bobbin with thread, places it on her sewing machine and then presses her foot down to begin sewing. While she's doing this,she pretends to guide cloth through the machine. Each Tuesday afternoon,after the bell rings for the fourth period, Liu becomes a fashion designer. At the same time,the rest of the students at the High School Attached to Yunnan Normal University in Kunming are also having classes a little bit different from the usual ones. Some students dance,others create robots,and still others review films. These are just a few of the 28 elective courses the school began to offer last month. "The fashion design class has become the bright point of my week. I learn how to choose color1s and cloth as well as sewing and sketching skills. It's all helping me to realize the dream of becoming a fashion designer I've had since I was a little girl," Liu said. Design is Liu' s passion,but for other students the electives are more an opportunity to take a fun course that relieves the pressures of schoolwork. Some students,for example,are learning how to play bridge. Chen Xiejiao,15,is one of them. "Many people think that playing a card game like this in class is a waste of time. But in fact,bridge is a very challenging game that helps develop memory and math skills," she said. Li Ke,15, is studying robotics. "I hope to have built and designed my own robot by the end of the semester. It will be able to complete a task,like moving a bail from one place to another," he said .
