    Summer Activities

    Students should read the list with their parents/careers, and select two activities they would like to do. Forms will be available in school and online for them to indicate their choices and return to school. Before choices are finalised, parents/careers will be asked to sign to confirm their child's choices.

    When you were at school, the last thing you probably wanted to do was spend your weekends going to work. There was homework to do, sport to play and fun to have. But our parents probably persuaded us to find a job to earn some money and get some life experience. When I was a teenager I had a paper round: delivering newspapers to people's homes. I then progressed to a Saturday job in a supermarket: stacking shelves and working at the checkout.

    Today in the UK you are allowed to work from the age of 13, and many children do take up part-time jobs. It's one of those things that are seen almost as a rite of passage (成人仪式). It's a taste of independence and sometimes a useful thing to put on your CV (简历). Teenagers agree that it teaches valuable lessons about working with adults and also about managing their money.

    Some research has shown that not taking up a Saturday or holiday job could be deleterious to a person later on. A 2015 study by the UK Commission on Employment and Skills found that not participating in part-time work at school age had been blamed by employer's organizations for young adults being ill-prepared for full-time employment, but despite this, recent statistics have shown that the number of schoolchildren in the UK with a part-time job has fallen by a fifth in the past five years.

    So, does this mean that British teenagers are now afraid of hard work? Probably not. Some experts feel that young people feel going out to work will affect their performance at school, and they are under more pressure now to study hard and get good exam results-and a good job in the long term. However, Geoff Barton, general secretary of the Association of School and College Leaders, told BBC News that “Properly regulated (控制的) part-time work is a good way of helping young people learn skills that they will need in their working lives." In reality, it's all about getting the right balance between doing part-time work and having enough time to study and rest.

    When my father married my mother in 1943, he gave my mother a 1937 crown coin and told her to keep it in the back of her purse and not to spend it. This would mean that she always felt that she was protected and would always have money if she really needed it.

    When I was married in 1970, my husband, who had heard this story, obtained a 1937 crown coin for me and I have always kept it in my wallet, and I have always had enough for my needs.

    A friend recently fell on hard times, partly through external (外部的) circumstances and partly through poor planning. Friends and I have loaned her money, paid her bills, given her food, and even tried to teach her budget techniques, but none of them has been a solution. She has just slipped deeper and deeper into financial trouble and depression.

    Last week she looked pale and unwell, very depressed and hopeless, very sad for a friend to see and I then thought about how the crown coin, a physical reminder of another's care and love had protected me, so I went to the bank for a $ 100 dollar-bill.

    I told my friend the story and asked her to keep the $ 100 in the back of her wallet. It turned out that she didn't have a wallet, so she put the money in a little pencil case where she kept her coins. She immediately felt better—"I feel rich, and thank you for being a good friend," she said, and we were both a bit teary.

    I went home and remembered a little wallet I had that I'd never used, and thought, "I'll give that to my friend." I opened it, and inside, found $ 100.

    Facebook says it is working on technology to allow us to control computers directly with our brains. It is developing "silent speech "software to allow people to type at a rate of 100 words per minute, it says. The project, in its early stages, will require new technology to detect brainwaves without needing invasive operation. "We are not talking about monitoring your random thoughts," assured Facebook's Regina Dugan. "You have many thoughts, and you choose to share some of them. We're talking about monitoring those words. A silent speech interface（界面）-one with all the speed and flexibility（灵活）of voice. "

    Ms Dugan is the company's head of Building 8, the firm's hardware research lab. The company said it intends to build both the hardware and software to achieve its goal, and has employed a team of more than 60 scientists and academics to work on the project.

    On his Facebook page, Mark Zuckerberg added, "Our brains produce enough data to stream four HD（高清）movies every second. The problem is that the best way we have to get information out into the world-speech-can only send about the same amount of data as a 1980s modem. We're working on a system that will let you type straight from your brain about five times faster than you can type on your phone today. Finally, we want to turn it into a wearable technology that can be produced in quantity. "

    Technology is going to have to get a lot more advanced before we can share a pure thought or feeling. but this is a first step. Other ideas detailed at the company's developers conference in San Jose included work to allow people to "hear" through skin. The system, comparable to Braille, uses pressure points on the skin to pass information. "One day, not so far away, it may be possible for me to think in Chinese, and you to feel it instantly in Spanish,"Ms Dugan said.

When you take to the seas on a cruise(游船度假), you usually think you are leaving solid ground behind, but the Celebrity Solstice brings a whole new experience to its passengers. Aboard the 317m-long ship is a half-acre lawn(草坪). The Celebrity Solstice is the first cruise ship ever to house live grass.

Nikolas Asproudas, the ship's environmental officer told New Zealand Neus, It was a crazy idea to start with. For five years now, they have been saying that this lawn is the most walked lawn in the world. It's a symbol of honor, particularly because the lawn on the top deck of the ship has special challenges with growth at sea, including "burns" from the salt water, which must be washed off immediately and clearance checks before the ship can pull in to shore.

The lawn is grown in silica(二氧化硅)sand rather than soil, which not only reduces weight, helping the ship's stability, but also agrees with restrictions and helps control pests that may otherwise stay on the grass.

Asproudas sends the Captain of the ship a weekly report on the status of the lawn. "We know that the Australian and New Zealand, authorities are very strict with the grass, and of course, they have to check before we come if, everything's OK," said the Captain.

The lawn is a source of pride for Asproudas, so. when there are problems with it, he says, "It brings me some sad feelings, but I need to be strong, because I know that it will recover within one week." All of the crew's hard work to maintain the "backyard" is appreciated by its many guests, including some that say the: Celebrity Solstice's lawn is better than theirs at home. Two recent passengers aboard said, "We're having a drought at home so…it was brilliant!"

Though the option of walking barefoot through a grassy field on a moving cruise ship seems terrific, there are many other ships that are trying to outdo one another with even more surprising guest options.
