    “Indeed,” George Washington wrote in his diary in 1785, “some kind of fly, or bug, had begun to eat the leaves before I left home.” But the father of America was not the father of bug. When Washington wrote that, Englishmen had been referring to insects as bugs for more than a century, and Americans had already created lightning-bug(萤火虫). But the English were soon to stop using the bugs in their language, leaving it to the Americans to call a bug a bug in the nineteenth and twentieth centuries.

    The American bug could also be a person, referring to someone who was crazy about a particular activity. Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs, and the like.

    Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burglar alarm, from which comes the expression to bug, that is, “to install (安装) an alarm”. Now it means a small piece of equipment that people use for listening secretly to others' conversation. Since the 1840s, to bug has long meant “to cheat”, and since the 1940s it has been annoying.

    We also know the bug as aflawin a computer program or other design. That meaning dates back to the time of Thomas Edison. In 1878 he explained bugs as “little problems and difficulties” that required months of study and labor to overcome in developing a successful product. In 1889 it was recorded that Edison “had been up the two previous nights discovering ‘a bug' in his invented record player.”

    Most people have heard of Shakespeare and probably know something of the plays that he wrote. However，not everybody knows much about the life of this remarkable man，except perhaps that he was born in the market town of Stratford upon Avon and  that he married a woman called Anne Hathaway. We know nothing of his school life. We do not know，for example，how long it lasted，but we presume that he attended the local grammar school，where the principal subject taught was Latin.

    Nothing certain is known for what he did between the time he left school and his departure for London. According to a local legend，he was beaten and even put in prison for stealing rabbits and deer from the estate of a neighboring landowner，Sir Thomas Lucy. It is said that because of this he was forced to run away from his native place. A different legend says that he was apprenticed to a Stratford butcher，but did not like the life and for this reason decided to leave Stratford.

    Whatever caused him to leave the town of his birth，the world can be grateful that he did so. What is certain is that he set his foot on the road to fame when he arrived in London. It is said that at first he had no money or friends there，but that he earned a little by taking care of the horses of the gentlemen who attended the plays at the theatre. In_time ， as he became a familiar figure to the actors in the theatre，they stopped and spoke to him. They found his conversation so brilliant that finally he was invited to join their company.

    A disease called “Panama” is threatening supplies of the world's most popular fruit—banana.Two years ago,the United Nations warned that the "Panama disease" could destroy "much of the world's banana crop."Since then,things have not gotten better.A new outbreak was discovered last year in Australia.The disease started in Asia in the 1990s, and later spread to Africa and the Middle East.

    World health officials worry the disease could travel to Latin America,one of the top banana producers in the world.All this is a big concern because bananas are an important source of income and nutrients for millions of people.They are grown in 135 tropical nations.The United Nations lists bananas as one of the most important foods, along with rice,wheat and corn.

    Randy Ploetz is a professor at the Tropical Research & Educational Center at the University of Florida.Many consider him as America's top banana expert.As he explained,Panama disease affects the Cavendish banana.The Cavendish is one of more than 500 kinds of bananas.But it is the most popular.

    “The industry is waking up to the problem,”Ploetz said.“They are pretty scared.”He was speaking Thursday by telephone from Miami,Florida,where he is among 1,000 people attending the International Banana Congress.The meeting was supposed to take place in Costa Rica,but was moved at the last minute.There were concerns banana growers could spread Panama disease from dirt collected on their shoes,Ploetz said.

    Ploetz said reports that Cavendish banana production could end are not correct.But if the disease spreads to Latin America,it could hurt the world's economy along with food supplies for millions of people.Still,he said there is reason for hope.Scientists in Australia are working on a genetically engineered banana that might not be at risk of getting Panama disease.

    Once I was troubled by tourists to do a favor for them—take their photos. Sometimes they complained that the photos I took were not good.

    Now fellow travelers trouble me in a different way—with their selfie sticks (自拍杆). I fear my head will be knocked or my eyes poked (戳) by the poles with mobile phone cameras put on them.

    Admittedly, it is a good invention. With a cool $3, you can take solo or group photos without asking for a favor from strangers. But if you want to take your selfie sticks out to travel to the West, think twice. Selfie-sticks bans have been spreading in some of the world's important museums, galleries, parks and soccer stadiums including Disney. Visitors have to leave their selfie sticks in a locker before entering to protect paintings, individual privacy and the overall visitor experience.

    In China, selfie sticks are still widely used. People would do anything to take a perfect selfie and don't pay attention to their surroundings and other travelers. Many examples have shown things could go horribly wrong when people were taking selfies. For example, earlier this year, a starfish died at the Shanghai Science and Technology Museum after a visitor took it out to take a selfie, and last year a criminal was caught by the Chinese police after the criminal posted a selfie of himself on Wudang Mountain and shared it on social media, according to the Xinhua News Agency.

    Thus, I strongly advise travelers not to take a selfie in a crowded public place, indoors or at any sensitive places such as cemeteries and memorial places, especially when the police are looking for you. If you are a die-hard selfie fan, there are some options cooler than a selfie stick. One is a waterproof (防水的) wrist-band called a “pop stick”. Just like the slap bracelets (手镯) we used to wear when we were kids, it unrolls into a stiff selfie stick. Another one is “selfie ring”, an accessory that helps you stick your phone to your hand so you can snap better selfies.

Michelle was played by twins Mary-Kate and Ashley Olsen. The Olsens are now active in the fashion world. One episode of Fuller House even joked about their absence.
