When my sister Mertie told me she had put out tomato plants last summer, I was quite impressed.

    Since she was a garden-beginner, Mertie researched exactly how far apart to space her tomato plants; what kind of fertilizer to use; how to keep away the bugs, etc. Once they were planted, she took care of them daily, anxiously awaiting the juicy tomatoes to appear. But, day after day, her plants were tomato-less while all of her neighbors who had also put out tomato plants were already enjoying the fruit of their labor.

    Frustrated, Mertie gave in and went to the market to search fresh tomatoes. While paying, Mertie told the farmer her troubles. The farmer paused to think for a moment and then asked, "Well, what kind of tomatoes did you plant?"

    "I think they were called Big Boy," Mertie remembered.

    "Well there's your problem," the farmer explained. "Big Boy and Better Boy tomatoes have a 95-day growing period whereas regular tomato plants produce fruit in as few as 70 days…you just have to wait a little longer for the Big Boys."

    With that new knowledge, Mertie went home with excitement, knowing they would be worth the wait.

    Thinking about my sister's gardening experience, I had to smile. She just didn't know that Big Boy tomatoes took longer--neither did I — but once she discovered that information, she was no longer discouraged and upset about the lack of tomatoes on her plants. Instead, she was encouraged and excited to see them a few weeks later.

    It makes me wonder how many of us have "Big Boy" dreams in our hearts, yet we just don't realize that they are of the "Big Boy" variety so we are discouraged and worn out with the waiting process. Instead of waiting with excitement, we give up on our dreams and figure we must have done something wrong to stop them from coming to pass. Frustrated, we see other people's dreams coming true, and we wonder why ours haven't yet been achieved.

    Construction on Knolly's Tunnel began in 1896, and it was opened on August 13th, 1898 by the man it was named after--Sir Clement C. Knolly, Acting Governor of Trinidad. It linked Rio Claro with Port of Spain. Its architecture is still admired and studied today, and many are amazed that Knolly's Tunnel has stood up to the earth's movement over so many years.

    Much research is being done on the tunnel. At the top of Knolly's Tunnel are cottages covered with leaves, where visitors can sit and enjoy the beauty of nature. Standing at the beginning of Knolly's Tunnel, you can see nothing but the tiny light at the end. The train tracks have been removed and replaced with small stones. Visitors can drive through the tunnel or walk through, but should do so in groups for safety. In the old days, there were no lights, but now there are street lights on the way to the tunnel, though not inside.

    On your way in, you may notice some manholes on the walls of the tunnel. These were there for individuals to step into for safety as the train passed. Knolly's Tunnel can be accessed through Tabaquite and through Mitchell Gap. The road was recently improved, but is better when you enter from Tabaquite, and there are signs on the road directing you to Knolly's Tunnel.

    On the drive to Knolly's Tunnel there are two other cottages where visitors can sit and just enjoy nature. At the site itself, there is nothing to purchase to eat or drink, but in Tabaquite there are several bars, a restaurant, and food outlets. A gas station and a health centre are also close by.

    For those who admire architecture, Knolly's Tunnel is a must-see when visiting Trinidad. For the nature lovers, there is no better place for them to be and for the historians, they can walk or drive through Knolly's Tunnel knowing that many of our ancestors toiled (worked hard) on its structure. So when you visit Trinidad, don't forget to take a look at Knolly's Tunnel!

    Facebook is an American online social media and social networking service. The Facebook website was launched on February 4, 2004, by Mark Zuckerberg, along with fellow Harvard College students and roommates.

    The founders had limited the website's membership to Harvard students at first; however, later they expanded it to various other universities, and eventually to high school students as well. Since 2006, anyone who claims to be at least 13 years old has been allowed to become a registered (注册了的) user of Facebook, though differences exist in the youngest age requirement, depending on local laws. Facebook has more than 2 billion monthly active users as of June 2017. As of April 2016, Facebook was the most popular social networking site in the world, based on the number of active user accounts.

    Facebook may be accessed by a large range of desktops, smartphones over the Internet and mobile networks. After registering to use the site, users can create a user profile (简介) showing their names and so on. Users can add other users as "friends", exchange messages, post photos and so on.

    Facebook makes most of its income from advertisements which appear on screen, marketing access for its customers to its users.

    The blooming of social media and interactive smartphone-based apps has proved that e-marketing is an unchangeable trend. In the case of China, the latest battlefield is beauty camera apps, which have become an overnight hit in the West.

    ⒈MeituPic

    Developed by the Xiamen-based Meitu Inc MeituPic is the company's flagship beauty camera app and was the first to become a big hit among Western users. The app has drawn some 456 million users, who use it to post more than 6 billion photos every month.

    In addition to MeituPic, Meitu Inc has developed a series of beauty camera apps such as Beauty Plus, Poster Labs and Meipai, each specializing in facial feature improvement, video editing and many other features.

    ⒉Pitu

    Tian Tian Pi Tu, is a beauty app developed by China's Internet giant Tencent. Similar to other photo-editing apps, Pitu offers a number of beautifying filters, blemish(瑕疵) removing tools and virtual makeup choices for users to choose from.

    Launched in 2014, Pitu has accumulated 106 million monthly active users (MAUs). While the number is not as impressive as that of Meitu's apps, some argue that the user base of Tencent's gaming products and chat applications, such as QQ and WeChat, gives Pitu great potential for further growth. According to Chinese app watchers, Pitu's target audience is younger and more individualized than that of MeituPic. 80 percent of Pitu's users are younger than 25, giving the app more room to try out more new features.

    ⒊FaceU

    In contrast with most other beauty apps, FaceU, focuses more on the social feature, encouraging users to video chat with friends and even strangers while playing with its fun stickers (贴纸) — and the strategy is undoubtedly working. Launched in 2016, the app, which mainly targets female users between 15 and 35, has twice made it onto the Apple store's Chart for top apps.

    More than 20 years ago, a skeleton called Little Foot turned up in a South African cave. The nearly complete skeleton was a member of the human family. Now researchers have freed most of the skeleton from its stony shell and analyzed the fossils (化石) and they say 3.67-million-years-old Little Foot belonged to a unique species.

    Researcher Ronald Clarke and his colleagues think Little Foot belonged to A. Prometheus (普罗米修斯南猿). Clarke works at the university of the Witwatersrand in Johannesburg South Africa. He studies fossilized humans and our relatives. Their foundings, published in four papers, have suggested the species A.Prometheus might have existed. Clarke has believed in that species for more than a decade, he found the first Little Foot's remains in a storage box of fossils in 1994. People began digging out the rest of the skeleton in 1997.

    Many other researchers instead argue that Little Foot likely belonged to a different species, which is known as A.africanus (南方古猿非洲种). Researcher Raymond Dart first identified A.africanus in 1924. He was studying the skull (头颅骨) of an ancient youngster called the Taung Child. Since then, people have turned up hundreds more A. africanus fossils in South African caves. Those include Sterkfontein, where Little Foot was found.

    The braincase is the part of the skull that holds the brain. And researchers found a partial braincase that Dart thought belonged to a different species in Makapansgat, one of those other caves. In 1948, Dart called this other species A. Prometheus, but he changed his mind after 1955. Instead, he said that braincase and another fossil at Makapansgat belonged to A.africanus. There was no A. Prometheus after all, he concluded.

    Clarke and his colleagues want to bring back the rejected species. They say Little Foot's distinctive skeleton, an adult female that is at least 90 percent complete, is solid evidence for it.

    Being forgiving to yourself and others can protect against stress and the harm it does to mental health, according to a new study in the Journal of Health Psychology.

    Researchers looked at the effects of lifetime stress on a person's mental health, and how more forgiving people got along compared with people who weren't so forgiving. To do this, they asked 148 young adults to fill out questionnaires that assessed their levels of lifetime stress, their tendency to forgive and their mental and physical health.

    No surprise, people with greater exposure to stress had worse mental and physical health. But the researchers also discovered that if people were highly forgiving of both themselves and others, that characteristic alone almost removed the connection between stress and mental illness.

    "It's almost entirely erased—it's zero," says study author Toussaint. "If you don't have forgiving tendencies, you feel the immediate effects of stress in a severe way. You don't have anything to cushion you against that stress."

    How a forgiving personality protects a person from the influence of severe stress is hard to determine. The researchers infer that people who are more forgiving may adopt better skills to deal with stress, or their reaction to major stressors(压力源)may be slow.

    Though more research is needed to fully understand the benefits of being more forgiving, Toussaint believes"100％"that forgiveness can be learned. His own previous research has shown that saying a short prayer on forgiveness can help people take the edge off. "I think most people want to feel good and forgiveness offers you the opportunity to do that," he says.
