Each morning Grandpa was up early sitting at the kitchen table, reading his book. His grandson wanted to be just like him and tried to copy him in every way he could.

One day the grandson asked, "Grandpa, I try to read the book just like you, but I don't understand it, and I forget what I understand as soon as I close the book. What good does reading the book do?"

The grandpa quietly turned from putting coal in the stove and replied, "Take this coal basket down to the river and bring me back a basket of water."

The boy did as he was told, but all the water leaked out before he got back to the house. The grandpa laughed and said, "You'll have to move a little faster next time," and sent him back to the river with the basket to try again. This time the boy ran faster, but again the basket was empty before he returned. Out of breath, he told his grandpa that it was impossible to carry water in a basket, so he went to get a bucket instead. The grandpa said, "I don't want a bucket of water; I want a basket of water. You're just not trying hard enough." The boy again dipped the basket into the river and ran hard, but when he reached his grandpa the basket was empty again. Out of breath, he said, "Grandpa, it's useless!"

"So, you think it is useless?" the grandpa said, "Look at the basket."

    The boy looked at the basket and for the first time he realized that the basket was different. It had been transformed from a dirty old coal basket and was now clean.

"Grandson, that's what happens when you read the book. You might not understand or remember everything, but when you read it, you'll be changed, inside and out."

    Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut the greenhouse gases they send out, which is thought to be responsible for global warming.

    Thanks to special bacteria in their stomachs, kangaroo flatulence (肠胃气胀) contains no methane and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas.

    While the usual image of greenhouse gas pollution is a billowing smokestack, pushing out carbon dioxide, farm animals' passing wind contribute a surprisingly high percentage of total emissions in some countries.

    “Fourteen percent of emissions from all sources in Australia are from enteric methane from cattle and sheep,” said Athol Klieve, a senior research scientist with the greensland state government. “And if you look at another country such as New Zealand, which has got a much higher agricultural base, they are actually up around 50 percent,” he said.

    Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers. But it will take researchers at least three years to isolate the bacteria before they can even start to develop a way of transferring it to cattle and sheep.

    Another group of scientists, meanwhile, have suggested Australians should farm fewer cattle and sheep and just eat more kangaroos. And about 20 percent of health-conscious Australians are believed to eat the national symbol already.

    It's low in fat, it's got high protein levels and it is very clean in the sense that basically it is free-range(放养的) animal,” said Peter Ampt of the University of New South Wales' institute of environmental studies.

    The UK's largest coffee seller, Costa Coffee, has promised to recycle half a billion coffee cups a year by 2020 to deal with plastic waste. The move, which means recycling the same number of cups it puts onto the market, would account for a big percentage out of the 2.5 billion takeaway cups thrown away across the country every year.

    Though marked as recyclable, most of paper coffee cups end up on landfill(垃圾场) or being burned due to the plastic lining(涂层) used to make them waterproof. By paying waste collectors to take coffee cups to certain places, Costa hopes to increase the rate at which cups are recycled. Finally, all a customer will need to do to make sure their cup avoids landfill is throw it into a standard recycling bin.

    Started following the Environmental Audit Committee's report recommending ministers take action to deal with coffee cup waste, the campaign has pushed for action from governments and businesses and promoted possible solutions. Starbucks has promised ￡7m to develop a "fully recyclable cup" following pressure from campaigners, while Waitrose, a supermarket, has planned to stop using disposable(一次性的) coffee cups from its stores by autumn.

    The company has entered into a partnership with five national waste collectors – Veolia, Biffa, Suez, Grundon and First Mile – that between them cover public spaces across the UK including hospitals, universities and transport hubs. The coffee company is also working with paper factories to make sure their products are recycled effectively. James Cropper, for example, has plans to upgrade 500 million cups a year to create plastic-free packaging. By building more partnerships with waste contractors in every area, Costa means to hit its half a billion mark within two years.

    With one report showing the number of takeaway drink cups thrown away in the UK is set to rise by a third by 2030, and the government recently failing to tax some coffee to discourage cup use, it falls to businesses to act on the huge amount of waste from their products.

    Commenting on the announcement, Environment Minister Therese Coffey said: "Congratulations to Costa on taking this significant step to help coffee lovers do the right thing and increase recycling. We all have a responsibility to our environment and this is a significant step by a British business which should increase the number of disposable coffee cups we recycle in this country." "We want to help companies become plastic free and through our 25 Year Environment Plan we are putting in place the aims to encourage all of us to play our part in ending the pollution of plastic waste in our natural environment."

    China will green light Internet medical services conducted by medical institutions as part of a broader push to promote Internet Plus Healthcare, those at a State Council executive meeting chaired by Premier Li Keqiang decided.

    Medical institutions will be allowed to provide online diagnostic services for some common and chronic diseases in patients' follow-up visits to their doctors. The top levels of hospitals will be encouraged to provide online services, including consultations (会诊), reservations and test result inquiries.

    As China joins the ranks of middle-income countries, the demand for health services has increased accordingly. Internet Plus Healthcare can help reduce the problem of inaccessible and expensive public health services that have long been a big concern for the general public.

    One decision coming out of the meeting says the intelligent review for health insurance will be applied and the one-stop settlement will be advanced. The real-time sharing of prescription and drug retail sales will be explored, as well.

    “We must waste no time in pushing forward the measures once the decisions made.” Li said. “In recent years, top-level hospitals in major cities have seen steady increases in the number of patients. Medical bills have become a heavy burden on families and high-end medical resources still fall short of meeting the growing demand of the public.”

    To solve the problem, a two-pronged (双管齐下的) approach must be taken. One is to establish medical partnerships to strengthen cooperation between major hospitals and community clinics. The other is to bring forward Internet Plus Healthcare to promote the sharing of quality medical resources.

    The government will see to it that long-distance healthcare services cover all county-level hospitals. So more efforts will be made to ensure that high-speed broadband network will be extended to cover medical institutions in urban and rural areas. Dedicated Internet access services will be set up to meet the needs for long-distance healthcare services.

    While we all try to find happiness, sometimes we still end up feeling low. While most people can control this feeling, low moods can stay with some, leading to depression. About 322 million people suffered from depression in 2015, according to a report by the World Health Organization in February. This is more than 4 percent of the world's population.

    Depression is described by the WHO as a mental disorder. It has several symptoms including sadness, loss of interest and feelings of low self-worth. In severe cases, depression may even lead to suicide.

    The number of people living with depression is increasing. The WHO reported a rise of 18.4 percent between 2005 and 2015. Young people are a group known to suffer with depression. “The pressures on today's youth are like no other generation, perhaps," Dan Chisholm, an official of WHO, told Reuters.

    In China, depression among young people is on the rise, Zhu Zhuohong, a psychology professor with the Chinese Academy of Sciences, told Xinhua News Agency. Competition to outperform others, especially in education, can cause a lot of pressure for Chinese youth.

    Almost 1.2 million Chinese people aged 15 to 24 suffer from depression, according to a report released by British science journal The Lancet in May.

    Luckily, more and more efforts are being made to deal with this problem. This year's World Health Day, held on April 7, will focus on depression. The day will highlight the “Depression: let's talk" campaign. The campaign aims to make sure that people with depression both seek and get help.

    One cold day in winter, my wife and I were walking back home from the grocery store as usual when we suddenly decided to walk into a coffee shop.

    My wife ordered a coffee at the counter. Just then, I saw a young woman in her thirties helping with a rather weak Mexican woman into the shop. Maybe it was the gentleness of their difficult experiences or an unclear familiarity (熟悉) with the situation that drew my full attention. I immediately had a strong wish to do something for them. Unfortunately, before I could think of anything reasonable to say, they left the coffee shop without ordering anything!

    When my wife returned, I told her about the two women and said," I missed the chance to do something for them." Strangely enough, though, they came back into the same coffee shop five minutes later. Unbelievable!" This is my chance," I thought out loud as my wife shared some creative possibilities. The two women ordered, took their place card and left the counter.

    After quickly finishing our coffee, we walked up to the counter and asked the smiling cashier (出纳员),"What is your most popular dessert (甜点)?" Chocolate Cake," she answered. With a childlike feeling of happiness, my wife made an unusual order." Can I buy a chocolate cake for the two women who were here just before us? But don't tell them it is from us. Just give them this card," she said while taking out a smile card. The cashier couldn't believe it." Do you do this all the time?" she asked." Not all the time, but just whenever the heart calls for it," I answered with a natural smile.

    We, my wife and I, are people of middle income (收入). That night, we had planned to have our once-in-a-while dinner at a restaurant. But walking out of that coffee shop, both of us stood upright and said," Let's eat at home today." It's more filling (能填饱肚子的) to give a chocolate cake than to eat it.
