   What will power your house in the future?Nuclear, wind, or solar power?According toscientists at the Massachusetts Institute of Technology(MIT)in the US, it might beleaves—but artificial(人造的)ones.

    Natural leaves are able to change sunlight and water intoenergy. It is known as photosynthesis(光合作用). Nowresearchers have found a way to imitate this seemingly simple process.

    The artificial leaf developed by Daniel Nocera and hiscolleagues at MIT can be seen as a special silicon chip with catalysts(催化剂). Similar tonatural leaves, it can splitwater into hydrogen and oxygen when put into a bucket of water. The hydrogenand oxygen gases are then stored in a fuel cell, which usesthose two materials to produce electricity, located eitheron top of a house or beside the house.

Though the leaf is only about the shape of a poker card, scientistsclaimed that it is promising to be an inexpensive source of electricity indeveloping countries.“ One can imagine villages in India and Africa not longfrom now purchasing an affordable basic power system based on this technology, ”said Noceraat a conference of the American Chemical Society.

    The artificial leaf is not a new idea. The first artificial leafwas invented in 1997 but was too expensive and unstable for practical use. Thenew leaf, by contrast, is made ofcheap materials, easy to useand highly stable. In laboratory studies, Nocera showedthat an artificial leaf prototype(原型)could operatecontinuously for at least 45 hours without a drop in activity.

    The wonderful improvements come from Nocera's recent discoveryof several powerful, new andinexpensive catalysts. These catalysts make the energy transformation insidethe leaf more efficient with water and sunlight. Right now, the new leafis about 10 times more efficient at carrying out photosynthesis than a naturalone. Besides, the device canrun in whatever water is available;that is, it doesn'tneed pure water. This is important for some countries that don't have access topure water.

    With the goal to “make each home its own power station” and“give energy to the poor”, scientistsbelieve that the new technology could be widely used in developing countries, especially inIndia and rural China.

(1)、Which of the following orders correctly shows how the artificial leaf is used to produce electricity?

a.artificial leaves split water into hydrogen and oxygen

b.the hydrogen and oxygen gases are stored in a fuel cell

c.the artificial leaves are put in water

d.the fuel cell uses hydrogen and oxygen to produce electricity

A、c,b,a,d B、c,a,b,d C、b,c,a,d D、c,a,d,b
(2)、The purpose of the scientists at MIT in developing the new artificial leaf is to________.

A、build up more power stations in the world B、provide cheaper energy for developing countries C、offer people in developing countries access to pure water D、gain a deeper understanding of the photosynthesis process
(3)、The main idea of this passage is ________.

A、an introduction to the history of artificial leaves B、an invention copying photosynthesis C、giving energy to the poor D、a mixture of water power and solar energy

    The World Health Organization says the widespread use of sugar in food products and drinks is a major concern in many areas. So WHO officials are calling on governments to require taxes on sugary drinks in an effort to limit their usage and popularity. The officials believe the taxes also would reduce the risk of health problems resulting from obesity.

    Obesity is a condition in which the body stores large, unhealthy amounts of fat. Obese individuals are considered overweight. A new report says that in 2014 more than one-third of the adults in the world were overweight, and 500 million were considered obese. The United Nations agency estimates that in 2015, 42 million children under age 5 were either overweight or obese. It says that number represents an increase of about 11 million during the past 15 years. Almost half of these boys and girls live in Asia and one-fourth in Africa.

    The U.N. agency blames unhealthy diets for a rise in diabetes cases. There are 422 million cases of the disease worldwide. WHO says 1.5 million people die from it every year. It says the use of sugar in food products, like sugary drinks, is a major reason for the increase in rates of obesity and diabetes.

    Temo Waqanivalu is with the agency's Department for the Prevention on Non-Communicable Diseases. He told VOA hat taxing sugary drinks would reduce consumption and save lives. Waganivalu noted that Mexico enacted a 10 percent tax on sugary drinks in 2014. He said by the end of the year, there was a 6 percent drop in the consumption of such drinks. Among poor people, the number of people who consumed sugary drinks dropped by 17 percent.

    The WHO says people should limit the amount of sugar they consume. It says they should keep their sugar intake to below 10 percent of their total energy needs, and reduce it to less than 5 percent for improved health.

    You know the feeling-you have left your phone at home and feel anxious, as if you have lost your connection to the world. "Nomophobia" (无手机恐惧症) affects teenagers and adults alike. You can even do an online test to see if you have it. Last week, researchers from Hong Kong warned that nomophobia is infecting everyone. Their study found that people who use their phones to store, share and access personal memories suffer most. When users were asked to describe how they felt about their phones, words such as "hurt" (neck pain was often reported) and "alone" predicted higher levels of nomophobia.

    "The findings of our study suggest that users regard smartphones as their extended selves and get attached to the devices," said Dr. Kim Ki Joon. "People experience feelings of anxiety and unpleasantness when separated from their phones." Meanwhile, an American study shows that smartphone separation can lead to an increase in heart rate and blood pressure.

    So can being without your phone really give you separation anxiety? Professor Mark Griffiths, psychologist and director of the International Gaming Research Unit at Nottingham Trent University, says it is what is on the phone that counts-the social networking that creates Fomo (fear of missing out).

    "We are talking about an internet-connected device that allows people to deal with lots of aspects of their lives," says Griffiths. "You would have to surgically remove a phone from a teenager because their whole life is rooted in this device."

    Griffiths thinks attachment theory, where we develop emotional dependency on the phone because it holds details of our lives, is a small part of nomophobia. For "screenagers", it is Fomo that creates the most separation anxiety. If they can't see what's happening on Snapchat or Instagram, they become panic-stricken about not knowing what's going on socially. "But they adapt very quickly if you take them on holiday and there's no internet," says Griffiths.

Choose the one that fits best according to the information given in the passage you have just read.

    In the early decades of the United States, the agrarian(土地的) movement promoted the farmer as society's hero. In the minds of agrarian thinkers and writers, the farmer was a person on whose well-being the health of the new country depended. The period between the Revolution, which ended in 1783, and the Civil War, which ended in 1865, was the age of the farmer in the United States. Agrarian philosophers, represented most eloquently by Thomas Jefferson, celebrated farmers extravagantly for their supposed centrality in a good society, their political virtue, and their Superior morality. And virtually all policy makers, whether they subscribed to the tenets of the philosophy held by Jefferson or not, recognized agriculture as the key component of the American economy. Consequently, government at all levels worked to encourage farmers as a social group and agriculture as economic enterprise.

    Both the national and state governments developed transportation infrastructure, building canals, roads, bridges, and railroads, deepening harbors, and removing obstructions from navigable streams. The national government imported plant and animal varieties and launched exploring expeditions into prospective farmlands in the West. In addition, government trade policies facilitated the exporting of agricultural products.

    For their part, farmers seemed to meet the social expectations agrarian philosophers had for them, as their broader horizons and greater self-respect, both products of the Revolution, were reflected to some degree in their behavior. Farmers seemed to become more scientific, joining agricultural societies and reading the farm newspapers that sprang up throughout the country. They began using improved implements, tried new crops and pure animal breeds, and became more receptive to modern theories of soil improvement.

    They also responded to inducements by national and state governments. Farmers streamed to the West, filling frontier lands with stunning rapidity. But farmers responded less to the expectations of agrarians and government inducements than to growing market opportunities. European demand for food from the United States seemed insatiable. War, industrialization, and urbanization all kept demand high in Europe. United States cities and industries grew as well; even industries not directly related to farming thrived because of the market, money, and labor that agriculture provided.

    The biggest challenge faced by travelers, especially those who like to have a backpacking trip is how to ensure a steady supply of clean clothes. Now, thanks to a great invention called Scrubba Wash Pack, that worry may be a thing of the past.

    The portable washing machine was invented by Ash Newland in 2010, while he was planning to climb Mt. Kilimanjaro. Struck by the limited packing space, he got inspiration from traditional washboards to create a bag that could be used to clean clothes. Then he quitted his career as a lawyer and focused on perfecting the bag's design. By 2012, the bag was ready for the public. It weighed only 180 grams and required very little storage space, making it perfect for anymore wishing to travel light.

    Not surprisingly, the bag which was worth 55 dollars was an instant hit with travelers, university students and even passengers. However, Newland was not satisfied. He still saw a disadvantage with his invention—dirty clothes had to be carried around in a separate bag! The recently introduced Scrubba Wash Pack solves that problem.

    In order to make the pack active, dirty clothes are placed inside the bag along with two or three liters of water. The bag is then shut tightly to ensure all air is squeezed out and the colors are massaged for a few minutes. After a quick wash, they are clean and ready to be dried. According to Newland, the pack can clean anything from jeans to smelly socks! What's even more amazing is that with a capacity to hold 13 liters of water, it can be used to wash more clothes at a time.

    The best part is that the 99-dollar pack that will be available for sale later this year, only weighs 300 grams and is completely foldable, making it easy to store when it's not in use. With the Scrubba Wash Pack, wandering through foreign cities searching for a washing shop, or paying for washing machines may soon be a thing of the past!

    Becca was 6 when she was told she had cancer on Sept. 8, 2014. She clearly remembers the bad days of her 26 months of non­stop treatment. Luckily, Becca celebrated her final treatment on Nov. 13, 2016, and she has been cancer­free ever since. But she was thinking about what her life was like while experiencing treatment.

    I was never able to do much, and that's what the kids lying in their hospital beds right now experience, asking their mom and dad, "When are we leaving? When can I play with my friends?" So I decided I have to help them.

    In February, 2017 Becca came up with the idea for Knots and Arrows, a company that makes bracelets (手镯) out of swimsuit materials (泳衣布料). Part of the money made from each bracelet goes to the organizations that help people with cancer.

    Becca created the company with her father, Gerhard Salmins. Gerhard Salmins once had cancer and already recovered from it. "I would be in the hospital sitting there crying and then my dad would come in and he would play games with me," she said. "It made me forget about what I was going through." Becca said the name of the organization shows the motto (座右铭) she stuck to through her personal cancer journey.

    Her organization has already given thousands of dollars to research organizations and families in need. Becca said she hopes her bracelets will make people remember that great things can result from small changes. "No matter what age you are, what you look like, how you act, you can make a difference!" she said.
