I have a neighbor who is a capable, fashionable, seventy-year-old, single woman. Her name is Grace. Grace was laid off from her job a little over two years ago and has been living off her savings ever since but not officially "retired". Grace called me up one day about this time last year and asked if I had a ladder. She needed to clean out her gutters (水槽) on the roof and wanted me to hold the ladder.

    She didn't want me to climb up and clean the gutters. She just wanted me to hold the ladder. As it happened I did have a ladder. I said: “The leaves are going to fall off the trees in a month, why don't we wait till they finish and do it then?” She agreed and naturally we didn't talk about it again until spring. Spring in Tennessee is wild and we talked about it over the course of three weeks in which it rained nearly every day, then I got busy and Grace went into seclusion (隐居).

    A couple of weeks ago, she told me she'd been spending too much money and decided to apply for a bar tending job at a local hotel. "Now I don't know about you all but I'd never considered what it would be like to apply for and begin a new job at the age of seventy. I'm fifty-three and the older I get, the more I think about how great it'll be if I can just get out of bed when I'm seventy." Anyway, she got the job, serving the bar and tending banquets at the hotel.

    The day when she left for her training at 6 am, I walked across the street with my ladder and cleaned out her gutters.

    When we don't understand each other's language, we can talk with the help of signs.

    A Frenchman was once travelling in England. He could not speak English at all. One day he went into a restaurant and sat down at a table. When the waiter came, he opened his mouth, put his fingers in it, and took out again. He wanted to say. "Bring me something to eat."

    The waiter soon brought him a cup of tea. The man moved his head from side to side. The waiter understood him and took the tea away. In a moment he came with a cup of coffee. But the man again refused it. He shook his head whenever the waiter brought him something to drink, for drinks are not food.

    When the man was going away, another man came in. This man saw the waiter, and he put his hand on his stomach. That was enough. In a few minutes there was a large plate of meat and vegetables on the table in front of him.

    So you see, we cannot understand the language of signs as well as we can understand the language of words.

    If you analyze people's actions, you will come to the conclusion that they all seek happiness. Every act is in fact a search for it, even if on the surface it doesn't look so. Happiness is always the main target.

    Going to the movies, eating in a restaurant and going to a party are all motivated by the desire to be happy. Who does not dream of a vacation in some fascinating locations, a new car, a new house, or the ideal match? All people daydream, and some even try to make their dream a reality. And why is that? In order to be happy!

    Many people endanger themselves by climbing steep mountains, entering unexplored caves, or diving into the deep of the ocean in order to enjoy the few moments of happiness. A thief may steal because he loves the thrill of danger, or because he desires to have quick money to spend. He is actually looking for happiness, though in a perverted way.

    Of course not all actions end in happiness. The motive is happiness, but the results do not always bring the desire. According to some spiritual traditions, we are spiritual beings in physical bodies. The spiritual part is always happy. Rather, it is happiness itself. But the physical body covers this happiness essence(本质). There is a constant desire to find out this happiness. This is the reason why happiness is constantly sought.

    However, there is no need to search for happiness or to create it, or to have all kinds of outer experiences and actions in order to feel it. On the contrary, everything has to be dropped in order to experience it. Every technique, which helps to relax the mind and calm the rush of thoughts will lead to happiness.

    The vast majority of green sea turtles in the northern Great Barrier Reef are female because of warmer temperatures due to climate change, which influences their sex, researchers said. Scientists are concerned populations of these animals could turn almost completely female.

    A recent study by the National Oceanic and Atmospheric Administration, California State University and Worldwide Fund for Nature Australia examined two genetically distinct populations of green sea turtles living in the Great Barrier Reef. The study found that a group of about 200,000 turtles living in the northern part of the reef was almost entirely female. While the southern population was 65 to 69 percent female, females in the northern group accounted for 99.1 percent of young turtles and 86.8 percent of adults.

    After combining their results with temperature data, the scientists found that most sea turtle populations are living above the most suitable temperature. The northern green turtles have been producing mainly females for more than two decades and that the complete feminization of this population is possible in the near future, making it clear that climate change is threatening the survival of these populations.

    Dermot O'Gorman, the chief executive of World Wildlife Fund Australia, said, “That's a very visible sign of the impact of climate change. But this is a quiet change.”

    O'Gorman said more urgent action on climate change is clearly needed, adding that some conservationists have already taken practical measures, such as using shade cloth on turtle nesting beaches to lower the sand temperature, and reducing by catch in the fishing industry.

    “Shade cloth can be used in certain places, but there's a limit to the scale you can do that,” he said, “Now every large male who can reproduce is going to be even more important.”

    One day after school, Bill walked past the shop on the street corner as usual. He stopped to look at the front row of shoes, and he felt sorry for himself.

    He really wanted to have a new pair for his birthday. He sadly walked away and

    thought of how to tell his mother. He knew she would give him anything if she could. But he also knew she had little money. He decided not to go home at once, because he looked worried and he didn't want his mother to worry about him. So he went to the park and sat on the grass. Then he saw a girl in a wheelchair. He found that the girl moved the wheels with her hands. Bill looked at her carefully and was surprised to see that the girl had no feet.

    He looked down at his own feet. "It was much better to be without shoes than without feet," he thought. It was not right for him to feel so sorry and sad. He went away and smiled, thinking he was luckier in life.

    Are you familiar with the greeting, "Can I add you on WeChat?" It seems like every time we meet new friends or colleagues nowadays, the first thing that springs to mind is adding each other on the app. Nevertheless, more than 80 percent of WeChat users report feeling stressed or anxious when they receive a large number of messages, according to a study done recently by the app's developer Tencent(腾讯). In other words, WeChat can overwhelm(使应接不暇) us, while also breaking down the boundaries between our work and private lives.

    Just think how easy it is now for bosses to hand out assignments during the holiday, so long as they have your WeChat contact. When you're at the cinema enjoying a romantic movie or having a barbecue in the backyard, you can never cut yourself off from the outside world unless you switch off your phone. Not to post something in WeChat Moments before replying to your boss first!

    Apart from interrupting your leisure time, WeChat can also reduce your productivity at work. For many office workers, logging in to WeChat on their computers at the start of the day has become routine. But what if browsing the Moments distracts us from doing the work? The app steals our time without us even noticing it, making us have the false belief that we are busy all the time.

    And as if that weren't bad enough, there're the "one-off" friends who take up space on our WeChat friend list. A handy way to check how many one-off friends you have is to take a look at your chat history with them. Sometimes, you only sent the initial friend requests so you could invite them to a WeChat group or inform them of something for your boss. Yet still, as your friend count(好友数量) ever goes up, it can make you feel the need to post selfies(自拍) and share details of your life in your Moments, just so you can stay up to date.

    With WeChat, all our spare time is swallowed up by the constant torrent of messages and our attention keeps getting diverted by Moments and pop-up ads. So it's time that we should do something to nip this problem in the bud.
