On a hot summer day, there are few things that are more wonderful than a nice cool pool.

    {#blank#}1{#/blank#}And it is completely relaxing. Of course, if you have children, there are certain measures you should take to keep them safe, whether you have a pool in your backyard or you are going to a public pool.

    People should never swim by themselves. Actually it only takes a second for people to become injured and drown(溺水). {#blank#}2{#/blank#}This is especially true for young children.

    Splashing(玩水) is fun, but don't take it too far. {#blank#}3{#/blank#}Kids love to go after one another through the water and to splash and jump around. But it is important to teach children not to jump on top of one another and to watch their surroundings in the water, so that they do not accidentally knock into others.

    If you have a pool, you must have a locking gate around your pool. {#blank#}4{#/blank#}Keep the gate knocked at all times, even when you are in the pool.

    Know the way out. {#blank#}5{#/blank#} Make sure that they know where all ladders are and how to enter and get out of the pool properly. Although your children may be able to lift themselves out of the pool using the side, that is not the safest way to go.

A.Kids should be taken good care of when they are swimming in the pool.

B.This is to prevent children from entering your pool without your knowledge.

C.And having someone there with you can make the difference between life and death.

D. Be sure to show all children the proper way to get out of the pool.

E.Even so, attempt to avoid getting any pool water into your mouth.

F. Jumping into the water seems like the perfect way to deal with the heat.

G. .Playing around in the pool can be a lot of fun.

    The iPhone, the iPad: each of Apple's products sounds cool and has become a fad(一时的风尚). Apple has cleverly taken advantage of the power of the letter “i” --and many other brands are following suit. The BBC's iPlayer--which allows Web users to watch TV programs on the Internet--used the title in 2008. A lovely bear--popular in the US and UK--that plays music and video is called “iTeddy”. A slimmed-down version(简装本) of London's Independent newspaper was started last week under the name “i”.

    In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms such as e-mail and e-commerce(电子商务) first came into use.

    Most “I” products are targeted at(针对) young people and considering the major readers of Independent's “I”, it's no surprise that they've selected this fashionable name.

    But it's hard to see what's so special about the letter “i”. Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head of the Language Center at King's College, London, “i” works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or interactive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn't have one clear definition(定义),” he says.

    “However, thanks to Apple, the term is now connected with portability (轻便).” adds Thorne.

    Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

    Along with “Google” and “blog”, readers of BBC Magazines voted “I” as one of the top 20 words that have come to define the last decade(十年).

    But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. However, as we entered the new century, the fashion disappeared.

    On May 14^th, 2016, three foreigners saved a drowning(溺水的)Chinese girl.

    Roman and Krill are Russian first-year college students. That Saturday, they were standing by the river near Shanghai Jianqiao University with their teacher, Bastien, a teacher from France at Jianqiao University. Then they saw someone “swimming”.

    The three said the “swimmer” seemed to be drowning. They rushed to help, though they didn't hear any cries, and found a girl in the water.

    Roman jumped into the water at once. He swam to the girl and quickly caught her arm. Then Krill came to Roman and held his hand. Bastien held on to the bank with one hand, while holding Krill with the other hand.

    “The girl almost pulled us into the water as she tried so hard to get out of the water,” said Bastien.

    A video showed that the rescue took less than five minutes. But it was really dangerous.

    The girl, 17 ,was a student from a nearby school. The three heroes spent some time with her to make sure she was safe and not hurt. Then the girl was sent to the international students' apartment of Shanghai Jianqiao University. Roman, one of the Russian students, later found he was injured in the back during the rescue. His cellphone also broke after being in the water. Students and teachers at Jianqiao University quickly heard the news. They were all proud of them. The three men also received some money as a reward from the girl's parents on Monday.

    Thanks to the three brave men, the girl didn't lose her life. The three heroes have been called foreign “LeiFeng”.

    My teenager son Karl became withdrawn after his father died. As a single parent, I tried to do my best to talk to him. But the more I tried, the more he pulled away. When his report card arrived during his junior year, it said that he had been absent 95 times from classes. In this way he would never graduate. I sent him to the school adviser, and I even begged him. Nothing worked.

    One night I was at work when I got a phone call. A man introduced himself as a head teacher, “I want to talk to you about Karl's absences (缺席).” Before he could say another word I choked up (硬咽), and said sadly, “I love my son. I've tried everything to get Karl to go back to school and nothing has worked. It's out of my hands.” For a moment there was silence on the other end of the line. The head teacher seriously said, “Thank you for your time.”

    Karl's next report card showed a marked improvement in his grades. He was even on the list of the best students at school. In his fourth year, I took part in a parent-teacher meeting. I noticed that his teachers were surprised at the way he had turned himself around. On our way home, he said, “Mum, remember that call from the head teacher last year?” I nodded. “That was me. I thought I'd play a joke but I heard you said. It really hit me how much I was hurting you. That's when I knew I had to make you proud.”

    Standing desks have become common across Silicon Valley, offering health benefits to those willing to work on their feet. However, due to their high price, they have failed to catch on until now. Recently, Ikea has brought out Bekant convertible(可变换的) standing desk that can become a normal desk at the touch of a button. The $500 adjustable desk can transform from a standard desk to a standing one, and Ikea hopes it could make the standing desk mainstream.

    Experts say that changing from a seated to a standing desk can improve productivity. Similar desks have become a common sight at tech firms such as Google, where some employees have even installed treadmill (跑步机) and bicycle desks.

    The desk is not the first "convertible" on the market. As early as 2013, Stir Kinect brought out an adjustable desk. The $3,890 Stir Kinect desk has a motor to raise and lower itself, changing it into a standing desk or a traditional desk. The desk can even be programmed to move up and down slightly, making it appear to take a gentle breath to remind the user to change their positions. To move between sitting and standing positions, owners simply double tap on the screen. The desk can learn the user's preferences over time and suggest the best seating position.

    The Stir Kinect desk was created by a team of ex-Apple and Disney engineers. It has a built-in touch screen to control and track movement, and can tell users exactly how many calories they burn by standing during their working day. It also has devices containing power points and USB ports for charging phones, to keep cables hidden.

    "Ikea's height-adjustable desk is great for opening up the lower end of the market, " said JP Labrosse, founder and CEO of Stir.

    Better known by his stage name KUN, Cai Xukun is a phenomenon, opening up the music industry in China.

    Last year, after participating in the reality TV show Idol Producer, receiving the most votes from fans, the singer-songwriter rose to fame overnight. At just 21 years old, Cai has topped Chinese music charts with multiple singles.

    On July 26, KUN released his newest single Young. Within just 20 seconds, it reached a million sales.

    KUN wrote the song to share his understanding of youth. He mixed R&B and electronic beats (节拍) to make it more cheerful. A reviewer wrote on QQ Music, "When you listen to the song, you just seem to go back to youth again."

    The song was an early birthday present to himself which he celebrated on Aug 2. KUN also hopes that he always has the courage to pursue (追求) his love of music, no matter what people think. "My works are like my children and I have put my best effort into them." he told the Global Times.

    Indeed, KUN has written and produced most of his songs on his own. "I want every piece of my work to have my own spirit in it," he told music website Soundigest, "I feel more enjoyment when I'm performing my own work."

    Although KUN loves performing onstage, when the lights go down, he prefers to fall back into his own world and darkness at night. "I always get inspired when it's quiet, late at night/' he told I-D magazine, "It's a great moment for me to create new things. Sometimes, I can write songs with a melody (旋律) I heard in a dream."

    To develop his introspection (反思) and find new inspiration, KUN attends different kinds of musical performances — from festivals to opera houses. "I just like to do everything, all for my music, all for my art," he told I-D.

    With such talent and dedication to music, it seems that KUN will continue to make his mark in the competitive Chinese music industry.
