    A student is learning to speak British English. He wonders: Can I communicate with Americans? Can they understand me? Learners of English often ask: What are the differences between British and American English? How important are these differences?

    Certainly! There are some differences between British and American English. There are a few differences in grammar. For example, speakers of British English say “in hospital” and “Have you a pen?” Americans say “in the hospital!” and “Do you have a pen?”. Pronunciation is sometimes different. Americans usually sound theirs in words like “bird” and “hurt”. Speakers of British English do not sound theirs in these words. There are differences between British and American English in spelling and vocabulary. For example, “color” and “honor” are British, “color” and honor” are American.

    These differences in grammar, pronunciation, spelling and vocabulary are not important, however. For the most part, British and American English are the same language.

    You carry a 1.3 kg mass of fatty material in your head that controls everything you will ever do. This fantastic control center lets you think, learn, create, and feel emotions. It also controls everything your body does. What is this amazing machine? It's your brain — a structure so amazing that the famous scientist James Watson called it ＂the most complex thing we have yet discovered in our universe＂.

    Imagine your kitten jumped onto the kitchen counter, and was about to step onto a hot stove. You would have only seconds to act. In situations like this, your brain reads the signals from your eyes and quickly calculates when, where and at what speed you need to run to save her. Then it tells your muscles to move. No computer can match your brain's great ability to download, process, and react to the flood of information from your eyes, ears and other sensory organs.

    If a bee lands on your foot, sensory neurons(神经元) in your skin send this information to your brain at a speed of more than 240 kilometers per hour. Your brain then uses motor neurons to send a message back to your foot: Shake the bee off quickly! Motor neurons can send this information at more than 320 kilometers per hour!

    Your brain contains about 100 billion tiny cells: neurons — it would take you more than 3,000 years if you tried to count them all. Whenever you dream, laugh, think, see or move, tiny chemical and electrical signals are racing between these neurons along billions of tiny neuron pathways. Believe it or not, the activity in your brain never stops. Countless messages fly around inside it every second, like a super-fast game of table tennis. Your neurons create and send more messages than all the phones in the entire world. And although a single neuron generates only a tiny amount of electricity, all your neurons together can generate enough electricity to power a light bulb.

    Cigarette ends are everywhere — littering our streets and beaches — and for decades they've been thought of as "unrecyclable". But a New Jersey based company, called Terra Cycle, has taken on the challenge, and has come up with a way to recycle millions of cigarette ends and turn them into industrial plastic products. Its aim is to recycle things that people normally consider impossible to reuse.

    Obviously it would be even better for the environment if everyone just stopped smoking, but the statistics show that although there has been an increase in anti-smoking ads and messaging, between 2000 and 2014, global sales of cigarettes increased by 8 percent, and a whole lot of those cigarette ends are ending up as trash. Since most of our litter eventually ends up in waterways, cigarette ends can surely pollute the surrounding environment. "It only takes a single cigarette end to pollute a liter of water," Terra Cycle founder, Tom Szaky, said. "Animals can also mistake littered cigarette ends for food."

    So how do you go about turning all those poisonous ends into something useful? Terra Cycle does this by first breaking them down into separate parts. They mix the remaining materials, such as the tobacco and the paper, with other kinds of rubbish, and use it on non-agricultural land, such as golf courses. The filters(过滤嘴) are a little harder. To recycle these, Terra Cycle first makes them clean and cuts them into small pieces, and then combines them with other recycled materials,  making them into liquid for industrial plastic products.

    They're now also expanding their recycling offerings to the rest of the 80 percent of household waste that currently can't be recycled, such as chocolate packaging, pens, and mobile phones. The goal is to use the latest research to find a way to stop so much waste ending up in landfill(垃圾填埋), and then get companies to provide money for the process. And so far, it's working.

    "We haven't found anything that we can't recycle, "communications director of Terra Cycle, Albe Zakes, said. "But with the amount and variety of packaging and litter in the world, we are always looking for new waste streams to address."

    Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.

     There are several major(主要) language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families.
