The world itself is becoming much smaller by using modern traffic and modern communication means.Life today is much easier than it was hundreds of years ago,but it has brought new problems.One of the biggest problems is pollution.To pollute means to make things dirty.Pollution comes in many ways.We see it,smell it,drink it and even hear it.

    Man has been polluting the earth.The more people,the more pollution.Many years ago,the problem was not so serious because there were not so many people.When the land was used up or the river was dirty in one place,man moved to another place.But this is no longer true.

    Man is now slowly polluting the whole world.

    Air pollution is still the most serious.It's bad for all living things in the world,but it is not the only one kind of pollution.Water pollution kills our fish and pollutes our drinking water.Noise pollution makes us angry more easily.

    Many countries are making rules to fight pollution.They stop people from burning coal in houses and factories in the city,and from putting dirty smoke into the air.Pollution by SO₂ is now the most dangerous kind of air pollution. It is caused by heavy traffic.We are sure that if there are fewer people driving,there will be less air pollution.

    The earth is our home.We must take care of it.That means keeping the land,water and air clean.And we must take care of the rise in pollution at the same time.

    It is popular to travel by bike in China. China has a huge population. And it is said that there is at least one bike for every two people. Of course, many people in China ride bikes for sport or exercise, but it is also a much more commonly accepted means of everyday transportation, as compared to countries such as the United States.

    If you are living for a long time in China, chances are that you will want to buy your own bike so that you can use it whenever you want. Even if you don't use a bike for everyday transportation, owning one can be a great way to enjoy the sights in the countryside. However, if you are just visiting China, renting a bike can be a more convenient choice.

    It is important to choose the correct bike for your use. You will find that in China, the one-speed style of bike is popular. These bikes are great if you want to ride around in the city to see the sights. They are quite comfortable and easy to ride. You can often rent a bike for a day for about 15 dollars.

    However, if you wish to ride on some of the rural paths, a mountain bike style would be a better choice. They are great for different kinds of road surfaces, providing for a safer ride. If you are planning to have a wish to tour and still be able to carry packages with you, then a touring bike would be the best choice. These are the most expensive to rent, but are very suitable for carrying packages and even some of your luggage along with you.

    Good afternoon, and welcome to England. We hope that your visit here will be a pleasant one. Today, I would like to draw your attention to a few of our laws.

    The first one is about drinking. Now, you may not buy alcohol in this country if you are under 18 years of age, nor may your friends buy it for you.

    Secondly, noise, Enjoy yourselves by all means, but please don't make unnecessary noise, particularly at night. We ask you to respect other people who may wish to be quiet.

    Thirdly, crossing the road. Be careful. The traffic moves on the left side of the road in this country. Use pedestrian crossings and do not take any risk when crossing the road.

    My next point is about litter（throwing away wasted material in a public place）. It is an offence to drop litter in the street. When you have something to throw away, please put it in your pocket and take it home, or put it in a litter bin.

Finally, as regards smoking, it is against the law to buy cigarettes or tobacco if you are under 16 years of age.

    I'd like to finish by saying that if you requires any sort of help or assistance, you should get in touch with your local police station, who will be pleased to help you.

    Now, are there any questions?

    I was born and raised in Minnesota, the USA, but as an adult I have mostly lived in Europe and Africa. I teach cross-cultural management at the International Business School near Paris. For the last 15 years, I've studied how people in different parts of the world build trust, communicate, and make decisions especially in the workplace.

    While traveling in Tokyo recently with a colleague, I gave a short talk to a group of 20 managers. At the end, I asked whether there were any questions or comments. No hands went up, so I went to sit down. My colleague whispered to me, “I think there actually were some comments, Erin. Do you mind if I fry?” I agreed, but I guessed it a waste of breath. He asked the group again. “Any comments or questions?”

    Still, no one raised a hand, but this time he looked very carefully at each person in the silent audience. Gesturing to one of them, he said, “Do you have something to add?” To my amazement, she responded “Yes, thank you.” and asked me a very interesting question. My colleague repeated this several times, looking directly at the audience and asking for more questions or comments.

After the session, I asked my colleague, “How do you know that those people had questions?” He hesitated, not sure how to explain it, and then said, “it has to do with how bright their eyes are.”

    He continued, “In Japan, we don't make as much direct eye contact as you do in the West. So when you asked if there were any comments, most people were not looking directly at you. But a few people in the group were looking right at you, and their eyes were bright. That indicates that they would be happy to have you call on them.”

    I thought to myself I would never have learned from my upbringing in Minnesota. Since then, I try to focus on understanding behavior in other cultures I encounter, and keep finding the bright eyes in the room.

    Once there were two mice. They were friends. One mouse lived in the country; the other mouse lived in the city. After many years the Country mouse saw the City mouse; he said, "Do come and see me at my house in the country." So the City mouse went. The City mouse said, "This food is not good, and your house is not good. Why do you live in a hole in the field? You should come and live in the city. You would live in a nice house made of stone. You would have nice food to eat. You must come and see me at my house in the city." The Country mouse went to the house of the City mouse. It was a very good house. Nice food was set ready for them to eat. But just as they began to eat they heard a great noise. The City mouse cried," Run! Run! The cat is coming!" They ran away quickly and hid. After some time they came out. When they came out, the Country mouse said. "I do not like living in the city. I like living in my hole in the field. For it is nicer to be poor and happy, than to be rich and afraid."

What is the best part of a typical relaxing summer day? Nothing is better than sitting in an armchair with a beer and some chips in your hand, enjoying the great comfort.

The much-loved combination of beer and chips is being exploited for the first time to deal with climate change. Chips firm Walkers has adopted a technique it says will cut CO₂ emissions (排放) from its production process by 70%.

The technology will use CO₂ captured from beer processing in a brewery (啤酒厂), which is then mixed with potato waste and turned into fertilizer. It will then be spread on UK fields to feed the following year's potato crop. Creating fertilizer normally produces high CO₂ emissions, but the technology adopted by Walkers makes fertilizer without generating CO₂. So, the beer-and-chips combination performs a double function. It stops the emission of brewery CO₂ into the atmosphere — and it saves on the CO₂ normally generated by fertilizer production.

This Creative win-win solution was developed with an approval from the UK government by a 14-employee start-up called CCm. The fertilizer was experimented on potato seed beds this year, and next year Walkers will install CCm equipment at its Leicester factory to prepare for its 2022 crop.

A decision has not yet been made on which brewery Walkers will work with on this. The new technology adds to carbon-saving techniques already under way. The firm has installed an anaerobic digester (厌氧消化池), which feeds potato waste to bacteria to produce a useful gas. The gas is burned to make electricity for the chip-frying process — so this saves on burning gas or coal.

The new system will go a step further by taking away potato "cake" left after digestion — and mixing the brewery CO₂ into it to make an enriched fertilizer which will help put carbon back into the soil as well as encouraging plant growth.

It's an example of scientists finding ways to use CO₂ emissions which otherwise would increase the over-heating of the planet.
