    Venom (毒液) from a local scorpion (蝎子) in Cuba is being used by Cuban scientists as an effective weapon to fight cancer. The venom, with stopping pain, anti-inflammatory (炎症) and anti-cancer properties, is the active ingredient in the medicine “Vidatox 30 CH,” which can be used to treat liver, brain, lung and other cancers. The treatment has been successfully used for more than four years in humans after being first tested in biological models. Labiofam, a Cuban laboratory, has breeding (繁殖) centers for both the Red Scorpion and Blue Scorpion. Each month, some 30,000 scorpions in Las Minas town, 270 km east of Havana are made to give the venom. After two years, the scorpions are released back into their natural habitat.

    Denyer Sanchez, a biologist from Labiofam, explained that the conditions are adjusted for reproduction, proved by the high number of breeding female scorpions. He said when the offspring (后代) becomes able to live in the environment, we release them because they do not have the necessary size yet to remove their venom, said Sanchez. Sanchez also said that there is still much to research on the exploitation process of scorpions, such as female death rate or the ability to survive of the released scorpions.

    Cuban research on the scorpion's venom began at the end of 1980s in Guantanamo province, the island's eastern tip, where a group of biologists and doctors became interested in the stories told by the peasants about the venom's benefits. However, the first discovery was made by Cuban biologist Misael Bordier. In 2001, Bordier visited Mexico's National Autonomous University (UNAM) and presented the research progress in a professional journal. Bordier died in 2005, one year before Cuba's Industrial Property Office gave Labiofam the rights to exploit the patent related to the venom.

(1)、How are the scorpions dealt with after their venom has been taken for two years?
A、Their bodies are used to make medicines. B、They are bred in the laboratory for research. C、They are raised to give birth to the offspring. D、They are set free into their natural habitat.
(2)、What can we infer from the passage about the research on scorpions?
A、The UN provided fund for the research team. B、There is still much to study in detail. C、The achievements will benefit animals. D、Many scientists doubt about the result of the research.
(3)、What can we learn about Bordier in the last paragraph?
A、He was given the rights to exploit the patent. B、He began his research at the beginning of the twenty-first century. C、He put forward the research progress in a professional journal. D、He was a peasant who told the stories about the venom's benefits.
(4)、What does this passage mainly talk about?
A、The various uses of scorpions in Cuba. B、Cuban biologists' research on strange diseases. C、Suitable conditions for Cuban scorpions to breed. D、Cuban scorpion venom's effect on fighting cancer.

    For the brave in the army, being sent away from home is just part of the duty. However, it's never easy especially for those with children. So, when I found out I was going to stay in South Korea for a year, I was nervous about how my five children, particularly my eldest daughter Abigail, would take the news since it meant I wouldn't be home to see her graduate from high school.

    To my surprise, Abigail told me not to worry and even suggested we make the news known among family members. "We've been lucky you haven't had to be sent abroad yet. Anyway, we can get connected through the Internet. See me on your phone." Abigail said. She stepped into many of my roles when I was gone. I wanted to find a way to thank her and show her how proud I was of her. I started planning the special surprise when my request to return home a few weeks earlier to attend Abigail's graduation ceremony(典礼) was approved.

    When my time in South Korea finally came to an end, I flew home, and stayed in a hotel. On Abigail's graduation day, I hid in an office behind the stage waiting until I heard her name called. I just kept thinking "Don't cry. Don't trip in your heels. Don't fall over." At last! Abigail was up on stage. I slipped up behind her, whispered in her ear, and around she turned! "I was just thinking, like, 'You aren't supposed to be here. What? What? How?' It was the biggest shock... I'm pretty sure my dad made people he didn't even know cry. Emotional for everyone." Abigail cried.

    You know what followed: embraces, kisses, tears, laughs, flowers, wishes...; aren't they what a family have in store?

    Times are a little tough at our house right now. Neither of us makes a lot of money, but years of experience have taught us how to walk between the raindrops and make it from one month to the next with a fair amount of grace. I cook a lot at home, more when we're facing difficult times. When I know that I have to keep us fed on not much money, I fall back on my grandmother's recipes. She taught me to cook.

    When I was a kid, my twin brother and I spent long summer weeks and Christmas vacations with my mother's parents in the mountains of North Carolina. Rather than go hunting with my grandfather on mornings, I found myself more and more in the kitchen with my grandmother, watching her making a lemon cheese pie with her soft hands.

    My great-grandmother died when my grandmother was 11 years old. As the eldest daughter, she was expected to take on all of the housework while attending school. Throughout the Great Depression, she learned how to make a little food go a long way. Vegetables were cheap, so she cooked a lot of them, mostly only using small amounts of meat for seasoning. Roast beef was a twice-a-month luxury, but there was nothing she couldn't do with a chicken, every part of it. Nothing went to waste.

    Now I understand that her food was sacred (神圣的). I feel connected to my grandmother and to hundreds of years of family when I'm in my kitchen making country food. In the delicious smells is a long tale of victory over hard times, of conquering starvation of not just surviving, but finding joy and pleasure in every meal of every day.

From grandmother I learned to take real satisfaction in feeding people. My grandmother would beam with pleasure over a heavily laden table and say: "Do you know what this would cost at the restaurant?" I never knew what restaurant in particular she had in mind, but I knew that the question was totally not fair, because no restaurant anywhere can cook like a grandmother. But now, thanks to her guidance and years of practice, I can.

    Thirteen-year-old Kaylee has a lot of friends—532, actually, if you count up both her Instagram followers and Facebook friends. And she spends a lot of time with them.

    But is it possible that Kaylee's online friendships could be making her lonely? That's what some experts believe Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.

    Could this be true? During your parents' childhoods, connecting with friends usually means spending time with them in the flesh. Kids played Scrabble around a table, not Words With Friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.

    Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of his time is spent on social media platforms like Instagram and Facebook.

    In fact, in many ways, online communication can make friend ships stronger, “There's definitely positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie, co-author of the App Generation.

    Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual worlds, we will have little time for our real world friendships.” says Rosen, a professor at California State University.

    Rosen also worries that today s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you didn't need someone to like your picture or share your tweet. You needed someone who would keep your secrets and hold your hand. You would like to talk face to face.

    The world's oceans will likely lose about one-sixth of their fish and other creatures within 100 years if climate change continues on its current path. Every degree Celsius that the world's oceans warm, their biomass is expected to drop five percent, a study found.

    The study predicts that if there is no change in the rate of worldwide greenhouse gas production, there will be a 17-percent loss of biomass by the year 2100. But, if the world reduces carbon pollution, biomass losses could be limited to only about 5 percent.

    Warming temperatures are the biggest issue. But climate change also produces oceans that are more acidic and have less oxygen. This also harms sea life. Much of the world depends on the oceans for food or work.

    The findings make sense and the possible effects of the predicted losses of animal life are huge. "Climate change has the potential to cause serious new conflicts over ocean resource use as the human population continues to grow," said scientists.

    Marine biologist Boris Worm, who helped run the study, added that the "building blocks of marine life—plankton and bacteria—may decline less heavily."

    "Those marine animals that we use directly, and care about most deeply, are predicted to suffer the most," said Worm. He works at Canada's Dalehousie University.

    Scientists had already believed climate change would likely reduce future ocean life. But past computer-based studies looked at only part of the picture or used only one model. The latest study used six different computer models to give the best picture look yet, William Cheung said.

    University of Georgia marine biologist Samantha Joye was not part of the research. But she praised the study as well researched and extremely detailed, and called it "an urgent call for action".

    You have just won ten million yuan in a lottery (彩票) - how would you spend it? Before you know it, ten minutes had gone on daydreaming. There is a time and a place for daydreaming, but we don't have much control over that. Isn't it worrying that an estimated 30 to 50 percent of our waking time is spent daydreaming? What if your dentist is having that lottery daydream while removing your rotten tooth?

    Some studies suggest daydreaming makes us unhappy because we are not focusing on what is around us but are instead thinking about the past or future. However, a recent study published in the journal Neuropsychologica finds that mind-wandering can be of benefit to us. The researchers measured the brain patterns of more than 100 people using an MRI (核磁共振成像) scanner. This data was compared with tests on creative ability and a questionnaire on how much their minds usually wandered. Those whose minds wandered the most scored higher in creative ability tests and had more efficient brain systems measured in the MRI machine.

    Being efficient at mind-wandering means you can zone out and then naturally switch back in without missing any important point or step. Christine Godwin, the lead author of the latest study from the Georgia Institute of Technology, says that if you are focusing on difficult tasks, your performance will drop if your mind wanders. “But when tasks are easy, people who have high cognitive ability can let their minds wander because it does not affect their performance. You may be thinking about upcoming goals or problem-solving. These are some of the positive sides to mind-wandering."

    Mind-wandering can vary between being more practical or more emotional. What mind-wandering seems to be best at, researchers say, is coming up with new solutions to old problems. So, it's not always a waste of time!
