Some unwelcome visitors from North America have been turning up in the waters off the coast of Great Britain.

    North American lobsters (龙虾) have been found in the North Sea (between Great Britain and Northwest Europe), far from their own habitat. The lobsters usually live along the eastern coast of Canada and the United States.

    It is impossible that the lobsters could have made the 5,600-kilometre journey on their own. They were probably brought to Britain and then got away from containers. Some of the lobsters that were caught had elastic bands (松紧带) holding their legs shut, like lobsters that are kept in containers in stores or restaurants.

    Many may have been “set free” from some ships passing through the area. Sometimes passengers order a live lobster from a tank in the dining room and then ask the waiter to throw it overboard instead of cooking it.

    According to official records, 26 North American lobsters have been caught in waters off Great Britain since 1988. However, it is believed many more have been found but not reported.

    It is against the law to let North American lobsters come into British waters. If they settle down in European waters, it would be bad for the local lobsters. The two live in the same place and eat the same food. But North American lobsters are larger, stronger and more aggressive (好斗的) than European lobsters, and they produce young more quickly.

    As a result, they could take food and space away from the local lobsters, and from other types of shellfish that live in the same area. These lobsters may also carry diseases that could harm the local lobsters.

    If Confucius (孔子) were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. He'd need a fan or a strong wind to help him put them out.

    While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It's nothing personal. Most Americans don't even remember the birthdays of their own national heroes.

    But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.

    In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually included Chinese art, history and philosophy (哲学). Some social scientists suggest that Westerners should take advantage of the ancient Chinese wisdom to make up for the drawbacks of Westerners philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.

    So the old thinker's ideas are still alive and well.

    Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.

    As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

    India has a very vast history and heritage (遗产). The country has witnessed some of the most important events in the past and every event has an effect of its own on the culture, religion, lifestyle, and economy of the country. This is one of the leading reasons why tourists prefer India to travel and explore. Historical tours in India provide everything that a traveler expects from his/her journey. These historical tours give an opportunity to study and explore Indian history.

    Historical tours of India generally consisted of four phases: ancient, medieval (中世纪的), modern India and contemporary (当代的) India. Some of the historical travel packages are:

    Forts and Palaces

    The rich cultural past of India is reflected in the countless forts (堡垒) and palaces across the country. Most of the forts were constructed as a defense device to keep the enemy away and palaces were made on the names of the kings and queens. Some of the famous forts and palaces are: Agra Fort (Agra), Fatehpur Sikri (Agra), Hawa Mahal (Jaipur), Amber Fort (Jaipur), City Palace (Jaipur), Gwalior Fort (Gwalior), Mysore Palace (Mysore), Red Fort (Delhi), etc.

    India Heritage Tours

    The main purpose of India Heritage tours is to make Indians as well as tourists familiar with the rich Indian legacy (遗产). The heritage of the country is at least 5000 years. Some of the heritage tours are: medieval heritage, Rajput heritage, Golden Triangle, splendid Gujarat, etc.

    South India Historical Tours

    The Southern India is known for its diversity and there are many places, which (景区) in South India include Goa, Cochin, Kerala, Munnar, Periyar, Kottayam and the list goes on and on.

    China is showing the world its great resolve in the global climate campaign with concrete and self-motivated efforts as well as serious commitment.

    At the opening ceremony of the Paris climate summit, Chinese President Xi Jinping restated China's plan made in June to cut its carbon emissions(排放)per unit of GDP by 60-65 percent from 2005 levels by 2030, and increase non-fossil fuel sources in primary energy consumption to about 20 percent.

    With a large population, China is facing increasing resource limits, severe environmental pollution and a worsening ecosystem, and its citizens are also becoming increasingly aware of environmental problems. Suffering environmental problems and seeing the efforts as important to transforming its economic growth pattern, the country has much at risk if climate change is left unattended.

    Actually, climate change efforts are already included in China's medium-and long-term program of economic and social development, and ecological efforts are the clear characteristics in China's 13th Five-Year Plan(2016-2020).

    Although it is and will be a developing country for a long time to come, China has been actively involved in the global campaign against climate change, now topping the world in terms of energy conservation and use of new and renewable energies.

However, China's development rights need to be respected. It is unfair to overstress China's status as one of the world's largest greenhouse gas emitters and regard it as the major part of responsibilities in the global fight against climate change.

    It is worthy of notice that China's emissions of greenhouse gases per person are far lower than those of developed countries, especially the United States, although rapid economic expansion and its population base have made it one of the biggest producers of the gases.

    To show its great resolve, Beijing in September also announced the establishment of an independent South-South cooperation fund of 20 billion RMB to help developing countries affected by global warming.

    While China is eagerly accomplishing its policy commitments, developed countries should stop questioning China's commitment to fighting climate change and pointing fingers, and start shouldering their due responsibilities instead.

    We discuss the issue of when to help a patient die, which was not talked about openly and little was written about it.

    The best way to bring the problem into focus is to describe two patients whom I cared for. The first, formerly a nurse, had an automobile accident. And there she was: in coma, on a breathing machine. One day, her husband and son came to see me. They told me their wife and mother was obviously going to die; she was a nurse and had told her family that she never wanted this kind of terrible death, being maintained by machines. I told them that while I respected their view, there was nothing deadly about her situation. The kidney(肾) failure she had was just the kind for which the artificial (人造的) kidney was most effective. While possibly a bit reassured, they were disappointed. Here was the head surgeon seemingly determined to keep everybody alive, no matter what.

    Within a few days the patient awoke from her coma. About six months later, the door of my office opened and in walked a gloriously fit woman. After some cheery words of appreciation, the father and son asked to speak to me alone. As soon as the door closed, both men became quite tearful. All that came out was, "We want you to know how wrong we were."

    The second patient was an 85-year-old lady whose hair caught fire while she was smoking. She arrived with a deep burn; I knew it would surely be deadly. At the time, there was a class discussing medical ethics(道德). The instructor asked me if I had any sort of ethical problem I could bring up for discussion. I described the case and asked the students their opinion. After the discussion, I made a remark that was, when looking back, a serious mistake. I said, "I'll talk with the nurses before we decide." The instructor and the students were shocked: "You mean this is a real patient?" The teacher of ethics was not accustomed to being challenged by actuality.

    A day or two later, when the lady was making no progress and was suffering terribly, we began to back off in treatment. Soon she died quietly and not in pain. As a reasonable physician, you had better move ahead and do what you would want done for you. And don't discuss it with the world first. There is a lesson here for everybody. Assisting people to leave this life requires strong judgment and long experience to avoid its misuse.
