A 16-year survey on the arctic Norwegian island of Svalbard found the reindeer（驯鹿）there have declined in weight by an alarming 12 percent. The reduction in average body-mass is being blamed on global warming.

    In research presented lately at a meeting of the British Ecological Society in Liverpool, scientists will explain how rising temperatures are making female reindeer difficult to obtain nutrients during important periods of being pregnant.

    Snow in Svalbard typically covers the ground for eight months of the year, which, combined with low temperatures, limits grass growth to June and July. But as summer temperatures have increased by around 1.5℃, grasslands have become more productive, allowing female reindeer to gain more weight by the autumn and therefore to conceive（孕育）more calves.

    However, warmer winters have brought with them greater rainfall which freezes when is settles on the snow, therefore locking out the reindeer from the life-supporting food below. As a result, female reindeer are becoming starved, causing them to give birth to much lighter young. The average mass of an adult reindeer in 1998, when the survey began, was 55kg, but by 2016 IT had dropped to 48kg.

    Professor Steve Albon, an ecologist at the James Hatton Institute in Aberdeen , said that, because the mammals have a relatively high surface-area-to-volume ratio（表面积与体积比）, they are no particularly energy efficient.

    Reindeer can often access the inadequate food sources beneath the snow by clearing IT away with their antlers（鹿角）, but they cannot break through the hard ice. Without access to the food in winter, calves are being born far lighter than they should be. Numbers of reindeer have also increased rapidly in the past 20 years, meaning that those which are born are facing greater competition for food. “The implication（含义）are that there may well be more smaller reindeer in the Arctic in the coming decades, but possibly at the risk of catastrophic die-offs because of increased ice on the ground,”said Professor Albon Despite the gloomy findings, reindeer appear to be suffering less from the impact of climate change than some other arctic species.

    China officially informed the World Trade Organization on Tuesday that it will ban the import of 24 different types of solid waste by the end of this year as part of a campaign to deal with environmental pollution and protect people's health.

    In response to growing public concerns over the potential environmental and health danger caused by the increasing amounts of solid waste imported into the country for recycling and treatment, China passed a special law in 1995 to control imports of waste materials, such as plastics, slag from steelmaking, unsorted scrap paper and discarded textile materials.

    A year later, the country published a list for solid waste imports and began implementing a permit system to control the import volumes and types of waste imported.

    However, due to the lack of effective supervision(监管) and the failure of relevant departments to fulfill their duties, solid waste imports have not been effectively controlled.

    So far, China is the world's largest importer of solid waste. According to the Ministry of Environmental Protection, China imported 7.3 million metric tons of plastic waste worth $3.7 billion in 2016, accounting for 56 percent of global imports of solid waste.

    Correct recycling of solid waste materials is an important part of the global economy, and moderate imports of scrap plastic, scrap paper and scrap rubber products, such as vehicle tires, can to some extent, make up for China's shortage of various raw materials.

    However, the lack of supervision has resulted in the country's severe soil and environmental worsening.

    Given that China's continuing efforts to push for industrial transformation and upgrading have resulted in a noticeable decline in the demand for the materials recycled from solid waste imports. It is right for the country to restrict such imports for the sake of the environment and public health, and to better adapt to the changed industrial structure.

    At the end of August this year I moved from London, UK, to a small town in Quebec, Canada, called Matane to work as an English language assistant. Patience is a word that has appeared in many forms over the past two months.

    I don't see myself as being the most patient person in the world but there was something that struck me on my first week of work. I had just finished a session with two students and just as they were leaving the classroom, one of the students turned back and said, “Thank you for your patience.” That was an early reminder of the importance of being patient as a teacher. It also made me reflect on the language teachers that I have had over the years, ones that demonstrated a high level of patience and understanding that has shaped my language learning path. Moreover, it helped me to realize the importance of demonstrating patience in the classroom as it can be the difference between building someone's confidence in a language or breaking down their confidence entirely.

    Living my life constantly in French is not easy but the people of Quebec are very patient. They repeat things several times and they are more than happy to wait while I find the correct words to express myself and find the correct word order. It's a learning process but with the patience of others, the process is slightly less nervous. At the end of the day, making mistakes shows you are trying and I think that is greatly appreciated by Quebecers.

    When I first arrived in Matane I kept getting headaches from having to concentrate all the time due to the language and even overhearing other people's conversations was hard work! I had to keep reminding myself that it would take time, and two months later the headaches are a distant memory and my ears have become more tuned to their accent. The key is to be patient with yourself.
