    Tiny microbes(微生物)are at the heart of a new agricultural technique to manage harmful greenhouse gas. Scientists have discovered how microbes can be used to turn carbon dioxide into soil­enriching limestone(石灰石), with the help of a type of tree that grows in tropical areas, such as West Africa.

    Researchers have found that when the Iroko tree is grown in dry, acidic soil and treated with a combination of natural fungi(霉菌)and other bacteria, not only does the tree grow well, it also produces the mineral limestone in the soil around its root.

    The Iroko tree makes a mineral by combining Ca from the earth with CO2 from the atmosphere The bacteria then create the conditions under which this mineral turns into limestone. The discovery offers a new way to lock carbon into the soil, keeping it out of the atmosphere. In addition to storing carbon in the trees leaves and in the form of limestone, the mineral in the soil makes it more suitable for agriculture.

    The discovery could lead to reforestation(重新造林) projects in tropical countries, and help reduce carbon dioxide in the atmosphere in the developing world. It has already been used in West Africa and is being tested in Bolivia, Haiti and India.

    The findings were made in a three­year project involving researchers from the Universities of Edinburgh, Granada, Lausanne and Delft University of Technology. The project examined several microbiological methods of locking CO2 as limestone, and the Iroko­bacteria way showed best results. Work was funded by the European Commission under the Future&Emerging Technologies(FET)scheme.

    Dr. Bryne Ngwenya of the University of Edinburgh's School of GeoSciences, who led the research, said: "By taking advantage of this natural limestone­producing process, we have a low­tech, safe, readily employed and easily operating way to lock carbon out of the atmosphere, while improving farming conditions in tropical countries."

(1)、The passage is mainly introducing          .
A、some useful natural fungi and bacteria B、a new way to deal with greenhouse gas C、a newly­found tree in West Africa D、the soil­enriching limestone created by scientists

    Getting on the school bus, like the possible dangers around the home, getting on the school bus can also bring its own set of dangers. There are several important safety measures that parents should be aware of when it comes to bus safety.

    Parents should always make sure that someone is taking charge of children at the bus stop to make certain clear ground rules which are in place and are being followed—particularly rules that forbid horseplay in and around the street.

    Teach children to ask the bus driver for help in picking up anything they may have dropped around the bus, as children getting dropped articles are often hit by the bus or another vehicle because they are not seen by the bus driver or by oncoming traffic.

    Children should be asked to take five large steps away from the bus when they get it off, and make sure that the bus driver can see you and look you directly in the eyes to signal it is OK to cross the street. It is still very important that children also look both ways as they cross the street.

    Inform children that they must never speak to any stranger who talks with them first and that they must never accept a ride from any person unless their parents tell them directly that it is OK. Teach kids that adults should ask other adults for help, not kids. If an adult asks a kid for help, that child should get another adult.

    If for any reason a child feels uncomfortable or unsafe at the bus stop they need to bring it to a parent's or caregiver's attention.

Remember, planning ahead is always the best safety measure. Follow these rules and your family will be off danger!

    Traditionally, robots have been hard, made of metal and other rigid material. But a team of scientists at Harvard University in the US has managed to build an entirely soft robot-one that draws inspiration from an octopus (章鱼).

    Described in science journal Nature, the "Octobot" could pave the way for more effective autonomous robots that could be used in search,rescue and exploration. "The Octobot is minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots" the study's authors wrote.

Robots built for precise, repetitive movements in a controlled environment don't do so well on rough terrains (地形) or in unpredictable conditions. And they aren't especially safe around humans, because they're made out of hard and heavy parts that could be potentially dangerous to their users.

    So researchers have been working on building soft robots for decades. They're taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter.

    But creating a completely soft robot remains a challenge. Even if engineers build a silicone (硅酮) body, it's still a grand challenge to construct flexible versions of essential parts, such as a source of power.

    "Although soft robotics is still in its early stage, it holds great promise for several applications, such as search-rescue operations and exploration," Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology' Center for Micro-BioRobotics, wrote in a comment. "Soft robots might also open up new approaches to improving wellness and quality of life."

    We're reading a book or opening an envelope when, all of a sudden, there's a sharp pain on our finger. You see a little bit of blood and realize you've just gotten a paper cut.

    Dr. Hayley Goldbach, a resident dermatologist at UCLA Health, spoke about why paper cuts are so jagged, how the element of surprise leaves us in more pain and how to make sure they heal quickly.

    Dr. Goldbach explained that one reason paper cuts hurt so much is where they occur: primarily on the finger. We have nerve endings all over the body," she said. "In places where there is refined movement and sensation--like the lips or tips of the fingers-they have a high density of nerve endings." These nerve endings are known as nociceptors and they send signals to the brain about things that could cause a break in the skin, such as extreme hot or cold temperatures and chemicals.

    Another reason why paper cuts hurt so much is that you're using your hands throughout the day meaning that the wound is constantly getting opened. "You often get paper cuts on the pad or the tip of the finger, different from where you'd get a knife cut," said Dr. Goldbach. "It's hard not to use your hands, so there's constant pressure on the wound without u chanee for it to heal."

    "The paper itself is another reason why these superficial cuts leave us in so much pain. Paper might look and seem smooth but, if you study it under a microscope, the edge is actually jagged." Paper is quite sharp jagged-it's a bit of serrated edge," said Dr. Goldbach."It cuts you pretty quickly before you have the chance to realize it."

    Additionally, paper cuts are quite shallow, which makes them even more annoying to deal with.

    Dr. Goldbach added that there are mental and emotional elements that cause paper cuts to hurt more than other cuts. "There's the psychological element of surprise, and it happens so quickly that you don't have time to withdraw your hand "she said" With some other injuries, you feel pressure so you have time to react."

    She also added that because we don't expect to hurt ourselves while working with paper, the surprise of cuts leaves us in further pain. "We tend to be careful with a knife-you're being careful on purpose: because you know there: s a danger, "said Dr Goldbach. While we are careful with knives, we are not so careful with paper.

    You are a member in a full-time school called "life". Each day here you will have the opportunity to learn lessons. You may like the lessons or hate them, but you have designed them as part of your curriculum.

    Why are you here? What is your purpose? Humans have sought to discover the meaning of life for a very long time. What we and our ancestors have to overlook is that there is no one answer. The meaning of life is different for every individual.

    Each person has his own purpose and distinct path, unique and separate from anyone else's. As you are traveling your life path, you will be presented with numerous lessons you will need to learn in order to achieve that purpose. The lessons you are presented with are specific to you; learning these lessons is the key to discovering and achieving the meaning of your own life.

    As you are traveling through your lifetime, you may meet challenging lessons that others don't have to face, while others spend years struggling with challenges that you don't need to deal with. You may never know why you are blessed with a wonderful marriage, while your friends suffer painful divorces, just as you cannot be sure why you struggle financially while your peers enjoy abundance. The only thing you can count on is that you will be presented with all the lessons that you specifically need to learn.

    The challenge, therefore, is to arrange yourself with your own unique path by learning individual lessons. This is one of the most difficult challenges you will face in your lifetime, as sometimes your path will be different from others. But don't compare your path with that of people around you and focus on the differences between their lessons and yours. You need to remember that you will only face lessons that you can learn and are specific to your own growth.

    Our sense of fairness is the expectation of equality. Life is not, in fact, fair, and you may indeed have a more difficult life path than others around you, deserved or not. Everyone's circumstances are unique, and everyone needs to handle his or her own circumstances differently.

    People generally like to pick out the best-looking fruits and vegetables when shopping for produce, but Canadian supermarket chain Loblaws is attracting customers with badly-shaped and imperfect produce at the price of 30% lower than normal-looking ones.

    A trial run of the ugly food line, named "Naturally Imperfect", began with only apples and tomatoes to choose from. Consumer(消费者) demand has been so huge that Loblaws is going to introduce more ugly vegetables and fruit like onions and mushrooms.

    All the produce that will be sold through Naturally Imperfect would otherwise have been used in juices, sauces, or soups, or have not been harvested at all. The director Dan Branson explained that this program benefited both food producers who would otherwise have to let abnormal produce go to waste, and consumers who could buy fresh produce at low prices. And he was right, considering how popular the line has become.

    "It really went well beyond our expectation," Branson said. "I think it really spoke to the fact that Canadians are out there really looking for some Choices."

    Of course, Canadians know that beauty is more than skin(外皮) deep, and they also recognize that they get the same flavor and nutritional (营养的) benefits in spite of appearances. The positive response to the offering of apples and potatoes showed the opportunity to expand the line and offer more choices at a greater price to Canadian families.

    "If you grow produce in your backyard, there will be a lot of produce that won't look as pretty as what you will see in a grocery store", said Branson. "And nature doesn't grow everything perfectly. I'd like to think if somebody were to take a NO Name Naturally Imperfect apple, put it right beside a No. 1 apple, close his eyes and eat them, there would be no difference."

Old China Café

    Eating here is a little like dining in a museum as the walls are lined with photos and memorabilia of the local Chinese laundryman's association. Chinese and Asian dishes keep regulars and travellers coming back for more. The menu changes monthly. 

San Pedro

    This restaurant serves Portuguese cuisine. Try the baked fish (seabass or red snapper) , curry chicken (can be quite spicy) , fried brinjauls and the black pepper crabs. Call ahead to reserve a table (and your fish) , because once their fish runs out, they will close for the day. 

The Bungalow

    Facing the hotel pool and the beach, this restaurant has indoor and outdoor seating. At night, the atmosphere is very romantic. The Chinese menu concentrates on traditional Hainanese dishes, but includes dishes such as fish curry, chicken rice and file t mignon. 

No. 7 Sup Corner

    Even if you miss this buffet-style restaurant at the road bend, you will not miss the number of cars parked at the road shoulder or the locals heading to it during lunchtime. It serves Malay dishes. First get your plate of rice, and then take whatever you would like to eat. Present your food plate to the lady at the counter and pay for it. Closed on Fridays and during Ramadan. Come early as there's always a crowd outside.
