Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut”, Joanna noted.

    Tina and Mark noticed the same changes in their 14-year-old daughter. “She used to cuddle up (依偎) with me on the sofa and talk,” said Mark, “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”

    Before age 11, children like to tell their parents what's on their minds. “In fact, parents are first on the list,” said Michael Riera, writer of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”

    Parents who know what's going on in their teenagers' lives are in the best position (位置) to help them. To break down the wall of silence, parents should produce chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental (精神上的) break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.

    Exploit your parking space

    An unused parking space or garage can make money. If you live near a city center or an airport, you could make anything up to £200 or £300 a week. Put an advertisement for free on Letpark or At my house park.

Rent a room

    Spare room? Not only will a lodger（房客）earn you an income, but also, thanks to the government-backed “rent a room” program, you won't have to pay any tax on the first £4500 you make per year. Try advertising your room on Roomspare or Roommateeasy.

    Make money during special events

    Don't want a full-time lodger? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money. Grashpadder can advertise your space.

Live on set

    Renting your home out as a “film set” could earn you hundreds of pounds a day, depending on the film production company and how long your home is needed. A quick search on the Internet will bring up dozens of online companies that allow you to register your home for free—but you will be charged if your home gets picked.

Use your roof

    You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment (around £14,000), and let you use the energy produced for nothing. In return, they get paid for unused energy fed back into the National Grid. However, you have to sign a 25-year agreement with the supplier, which could prevent you from changing the roof.

    Are you a different person when you speak a foreign language? That's just one of the questions the New Yorker's writer and native North Carolinian Lauren Collins explores in her autobiography, about her tough efforts to master French after marrying a Frenchman whose name —Olivier—she couldn't even pronounce properly. When in French ranges from the humorously personal story to a deeper look at various theories of language acquisition and linguistics (语言学).

    The couple met in London “on more or less neutral ground: his continent, my language.” But the balance shifted when they moved to Geneva for Olivier's work. The normally voluble (健谈的) Collins found herself at a loss — “nearly speechless.” The language barrier, and her dependence on her husband for simple things like buying the right cut of meat worsened her mixed feelings about “unlovely, but not ridiculous” Geneva. She comments, “Language, as much as land, is a place__To be cut off from it is to be, in a sense, homeless.”

    Her sense of alienation (疏离感) leads to an examination of America's miserable record when it comes to foreign languages, “Linguists call America 'the graveyard of languages' because of its singular ability to take in millions of immigrants and make their native languages die out in a few generations,” Collins writes. Educated in Wilmington, N.C., and at Princeton, she could — like the vast majority of Americans — only speak their mother tongue.

    Eight months after she moved to Switzerland, Collins gives up on the natural acquisition of language and finally attends a French course. As she struggles with grammar and vocabulary, Collins notes smartly that vert (green),verre (glass), ver (worm), vers (toward), and vair (squirrel) compose a quintuple homonym (同形异义). “Although it's difficult, French can try” she says.

    French is actually considered among the easiest languages for an English speaker to learn, especially compared to Arabic or Mandarin Chinese. Collins, whose notably rich English vocabulary includes glossolalia (nonsense speech) and shibboleth (catchword or slogan), finds plenty of terrific French words to love. She writes, “English is a trust fund, an unearned inheritance (遗产), but I've worked for every bit of French I've banked.”

    Unlike Jhumpa Lahiri, who became so hooked on Italian and used it to write In Other Words, Collins's goals for learning French were more modest, “I wanted to speak French and to sound like North Carolina.” She also wanted to be able to deal with chimney sweeps and butchers, communicate with her in-laws, and “to touch Olivier in his own language.” She admits that she feels different speaking French. ''Its austerity (朴素) made me feel more confused.”

    Readers looking for the romantic spark of classic cross-cultural love stories featuring an outgoing American and a shy Frenchman will find flashes of it here. Among the many cultural differences the couple argue over are her enthusiastic American habit of applying the verb love to express enthusiasm for shoes, strawberries, and husbands alike. But there's far more to Collins, book than fantastic comedy, and those who have experienced linguistic crossings themselves tend to find particular resonance (共鸣) in its inquiry into language, identity, and transcultural translation.

Arranged by chapters named for verb tenses, When in French works its way from The Past Perfect (Le plus-que-parfait) to The Present (Le Present) and The Conditional (Le Conditionnel). Collins ends on a delightful note with Le Futur—fitting for a new mother about to move with her hard-won French husband, French language, and Swiss-born daughter to the French-speaking city of her dreams, Paris.

    Meeting people from another culture can be difficult. From the beginning, people may send the wrong signal. Or they may pay no attention to signals from another person who is trying to develop a relationship.

    Different cultures emphasize the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in "small talk", usually over a glass of tea, before they do any job. In many European countries, like the UK or France, people find it easier to build up a lasting working relationship at restaurants or cafe rather than at the office.

    Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion, instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.

    Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values, however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.

    People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment will offer a wonderful chance for us to learn from each other.

    Jon Pedley is making a big change. He is giving up his life as a successful businessman for life of helping others. He is trading his beautiful farmhouse in England for life in a mud hut it Uganda, East Africa.

    Pedley admits that he has not always led a very positive life. At times he drank too much and got in trouble with the law. "I've always put the pursuit(追求) of money in front of everything else. As long as I was all right, I didn't care who I was hurting," says Pedley.

    But a visit to Uganda in 2007 gave Pedley a new outlook(观点) on life. He was amazed at what he saw and how much the people there appreciated the work he was doing. "I worked there for a few days and these people who have nothing thanked me by giving me bags of potatoes, which are a fortune for them," he said.

    Now Pedley is selling his business, his $1.5 million farmhouse, and his expensive car — and moving into a hut made of mud and boards in a small Ugandan village. There he will help run an organization that hopes to improve the quality of life for people in the village of Kigazi. He will help to build schoolrooms for children and tanks to hold clean water for villagers. Today, people in Kigazi must walk two miles to a hospital, so Pedley will help to build doctors' offices, too.

    Pedley's organization will also work with English teenagers who are in trouble. The teens will be sent to a "camp" in Uganda that Pedley will run. The teens will live in mud huts and help to build water, health and education facilities(设备) for kids in Kigazi, many of whom have lost their parents due to poverty or disease. Pedley hopes the teens will see a side of life that might help them turn around their own lives and set them on a new and more positive path.

There was an encounter that later sparked scientists' investigations into using jellyfish as a greater source of food, as well as a potential ingredient in medicines and nutraceuticals. In the summer of 2013, while Stefano Piraino was wandering along the rocky shoreline, he noticed a washed-up jellyfish. Then, he tore off a piece and put it in his mouth. It was salty, crunchy and crispy from the sun. "It was very tasty, " remembers Piraino, a zoologist. After a few days of lying on the shore, their stinging cells(刺细胞)are deactivated, Piraino explains. Still, he warns that people should not eat jellyfish straight out of the sea, because raw jellyfish contains bacteria that can cause food poisoning. 

Recently, there have been numerous reports of jellyfish blooms—seasonal events where there is a large and sudden increase in jellyfish numbers. These population explosions break the balance of ocean ecosystems, and have the potential to harm biodiversity and reduce fish stocks. 

Some scientists, such as Piraino, believe one solution is broadening our palates(口味)since the world is in urgent need of sustainable food resources. Jellyfish can be integrated into traditional recipes and local cuisine. Not only are they high in protein, but the microalgae inside the cells of some jellyfish are rich in fatty acids. In fact, jellyfish is already eaten across Asia. In China, jellyfish has been eaten for more than 1, 000 years, with jellyfish salad a popular delicacy. 

Jonathan Houghton, a senior lecturer in marine biology, believes that jellyfish can be a better source of collagen(胶原蛋白). There are a number of companies already using jellyfish as a substitute(替代品) for cow and pig collagen, which is often used in medical treatments for humans. One British company says collagen from jellyfish offers a better choice, because their collagen can work with a wide variety of human cell types.
