Growing roses is quite a difficult task without knowing the right way. If you are attracted by the beauty of roses and need some tips for growing them, read on for some tips about taking care of rose plants.

● You have to buy a good plant, preferably around two years old.

● While most rose plants can tolerate around six hours of sunlight every day, some varieties need eight hours of sunlight exposure. The shade-loving roses need only four hours of sunlight.

● You will have to soak(浸泡) the roots overnight, before planting. If you plant it in a container, then the watering should be done daily, whereas garden roses need water once or twice a week.

● The next point is the application of fertilizers（肥料）, which is mainly needed by rose plants in containers. Most of the varieties do not need fertilizers, as they can feed on the nutrients that exist in the soil. There is no need of fertilization during November and December, and the frequency of fertilization can be reduced during the summers, especially after April. It can be restarted in September and has to be increased during the growing periods.

● Cutting the stems promotes the growth of the plant and also aids flowering. It should be done regularly to remove dead or diseased leaves and stems.

Rose plants can be successfully grown by beginners too! With some care and consideration, all your efforts would definitely be worth it once you smell the fragrance of beautiful roses. 

    There are an extremely large number of ants worldwide. Each individual (个体的) ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles. For animals their size, ants have been astonishingly successful, largely due to their wonderful social behavior.

    In colonies (群体) that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achieve this level of organization. Where we use sound and sight to communicate, ants depend primarily on pheromone (外激素), chemicals sent out by individuals and smelled or tasted by fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit.

    In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy.

    Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective (集体的) intelligence greater than you would expect from its individual parts.

    When Johnny, a homeless man, spent his last $20, he wasn't looking at it as an investment — but it's about to pay him huge profits. After he helped a woman who ran out of gas, she returned the favor by raising a lot more on the Internet.

    Kate McClure, 27, was driving to visit a friend when she ran out of gas halfway. “He saw me pull over and knew something was wrong,” she wrote. “He told me to get back in the car and lock the doors. A few minutes later, he came back with a red gas can, using his last 20 dollars to make sure I could get home safe.”

    She couldn't repay him at that time because she had no cash with her. “I have been stopping by his spot for the past few weeks. I repaid him for the gas and gave him some clothes.”

    Kate decided to do more for him, so she started a crowdfunding(众筹) campaign on GoFundMe.com, and it quickly gained far beyond its initial $10,000 goal. When it reached $100,000, the fundraising page was shut down for a time at Johnny's request. Because he didn't want to seem like he was taking advantage of the situation. Finally, Kate said that she restarted it because the public interest had not decreased. She also added that Johnny planned to donate the rest to a good cause.

    According to the New York Post  Johnny wants to get a job at an Amazon warehouse and a department manager from the tech company has already reached out, saying he wants to help Jonny.

    A MENTORING (导师制) program is giving life changing opportunities to Banbury youth.

    Young Inspirations was founded two years ago to provide mentoring sessions for students and unemployed young adults aged 11 to 21.

    Alex Goldberg, the program's founder, said: "We set up Young Inspirations because we wanted to give young people experiences which will potentially be life changing and broaden their outlook.

    "We try to create work experience opportunities that will really make a difference to our youth. For example, we've secured internships (实习) with world­famous firms such as Honda."

    "At a time of funding cutbacks where schools are finding it more and more difficult to offer this kind of mentoring, it is extremely important that these opportunities are available both to help youth with their school work and grades and to give them opportunities which may help shape their futures." Kieran Hepburn, 14, is one of a group of Banbury youth who has benefited from the program so far. In October the Banbury School pupil was accompanied by Young Inspirations staff to Paris where he was an observer at the United Nations Educational, Scientific and Cultural Organization's (UNESCO) International Youth Forum (论坛).

    The event was held for young people from around the world, to seek their views on how the future of youth and education should look. Kieran joined several hundred observers mostly in their 20s and was the only UK school pupil to attend the event. Kieran thinks the trip was a life changing experience. "Before we left I didn't quite know what to make of it but when we got there we didn't stop, it was amazing, " he said, "We went to three or four hours of debates each day and then did something cultural each afternoon."

    The main theme of the forum was how youth can drive change in political and public life. It dealt with issues (问题) such as drug abuse, violence and unemployment.

    Kieran said: "It has really helped me to improve my confidence and social skills as well as my school grades and I was voted most improved pupil at school in August."

    The Young Inspirations mentoring sessions take place each Friday in Banbury. For details visit www.younginspirations.com.

    The school year has barely started in Denver, and French teacher Tiffany Choi is already worried that her students are suffering from absent-mindedness. The problem isn't texting, playing video games or passing notes. It's Denver's ongoing heat wave.

    "Today was a little bit hot, so I noticed kids were very sleepy and they were having to get up to drink water quite often." said Choi, who works at Denver's East High School. "If you lose too much water, and you have to keep going to the water fountain, that can take away from their classroom experience." While nodding off in class on a warm day may seem like a right of passage for the average teen, Choi's observation carries a bigger consequence than parched (干燥的) lips.

    "There's been quite a few media reports about teachers noticing that students weren't able to focus on hotter days," said R Jisung Park, a researcher, "Does a hotter climate during the school year actually affect the rate of learning?" The drops in academic achievement couldn't be explained by hotter weekends or hotter summers, but the trend was connected to higher temperatures on school days alone.

    The connection between lost learning and a greater number of hot days is one more example of how climate change is already affecting our lives-and it's an alarm bell for what we stand to lose in the future. Humans still have time to lessen the worst consequences of continued global warming. But unless significant changes occur in the next decade-which seem more and more unlikely—the world will be locked into an inescapable period of heat waves unlike our species has ever seen.
