Here is a page from a magazine called Future. Read the following information about things that may happen in twenty years.

    Cars will run on solar power (太阳能) and will be much cleaner and safer. For example, if you are too close to another car or if you are driving dangerously, your car will slow down or stop by itself.

    New cities will have to be built in the sea. Some cities on water will have two levels(层). People will live on the upper level, the lower level will be used for traffic, shops and factories.

    Biotechnology(生物技术) will make food better and healthier. Plants without insects or illnesses(病虫害) will be developed. The taste of fruit and vegetables will be better and food will be kept longer.

    Many new ways to cure(治愈) illnesses will be found. People will use products of genetic engineering (基因产品) to cure more illnesses. However, some new illnesses will appear.

Every single one of us can help to deal with climate change and prepare for the effects.

We all have an effect

on the environment through our use of resources (资源) and burning fossil fuels for everyday activities such as driving cars and heating our homes. If we all do our best to protect our environment, then we can make a real difference.

Consider the environmental effects of:

1       the energy used in your home

2       the way you travel

3       the food you eat

Do everything you can to reduce your carbon footprint (足迹) and not only will you be making fewer effects on the environment, but you511 probably find that you'll also save money and lead a healthier life.

Increasing water efficiency in your home reduces the amount of energy used for water treatment and can save money and fight against climate change at the same time.

Other things you can do

Here's a list of some simple things you can do that will help reduce your carbon footprint:

1       insulate (使隔热) your home

2       turn down your central heating by one degree (度数)

3       use energy efficient lighting

4       try not to fly

5       share a car with others

6       ride your bike for short journeys

7       eat local, seasonal, fresh, unprocessed (未加工的) food

8       reduce the amount of waste you produce and reuse or recycle as much as you can

    One day, Mr. Arnold was teaching a lesson, and things were going as normally as ever. He was explaining the story of human being to his pupils. He told them that, in the beginning, men were nomads (游牧); they never stayed in the same place for very long. Instead, they would travel about, here and there, in search of food, wherever it was to be found. And when the food ran out, they would move off somewhere else.

    He taught them about the invention of farming and keeping animals. This was an important discovery, because by learning to cultivate (耕作) the land, and care for animals, mankind would always have food steadily. It also meant that people could remain living in one place, and this made it easier to set about tasks that would take a long while to finish, like building towns, cities, and all that were in them. All the children were listening attracted by this story, until Lucy jumped up:

    "And if that was so important and improved everything so much, why are we nomads all over again, Mr. Arnold?"

    Mr. Arnold didn't know what to say. Lucy was a very clever girl. He knew that she lived with her parents in a house, so she must know that her family were not nomads; so what did she mean?

    "We have all become nomads again,” continued Lucy, " The other day, outside the city, they were cutting the forest down. A while ago a fisherman told me how they fish. It's the same with everyone: when there's no more forest left, the foresters go elsewhere, and when the fish run out, the fishermen move on. That's what the nomads did, isn't it?

    The teacher nodded, thoughtfully. Really, Lucy was right. Mankind had turned into nomads. Instead of looking after the land in a way that we could be sure it would keep supplying our needs, we kept developing it until the land was bare. And then off we would go to the next place! The class spent the rest of the afternoon talking about what they could do to show how to be more civilized (文明的).

    The next day everyone attended class wearing a green T-shirt, with a message that said "I am not a nomad!"

    And, from then on, they set about showing that indeed they were not. Every time they knew they needed something, they made sure that they would get it using care and control. If they needed wood or paper, they would make sure that they got the recycled kind. They ordered their fish from fish farms, making sure that the fish they received were not too young and too small. They only used animals that were well cared for, and brought up on farms.

    And so, from their little town, those children managed to give up being nomads again, just as prehistoric men had done, so many thousands of years ago.

    According to a national study, in the summer of 2013, the long-term(长期的) warm weather in the UK has made the number of butterflies increase.

    Around 46,000 volunteers(志愿者) took part in the year's Big Butterfly Count(统计), and they found 830,000 butterflies.Volunteers were asked to make a record.They would record how many times they found one of 21 different kinds of butterflies.

    Later, the scientists used the records to find out how many butterflies of different kinds were found across the country.Then, they compared the results to the year before.They found that there was a rise in the number of 15 kinds of butterflies, and some of them went up by 50% compared to recent years.They said the increase in butterfly numbers was a result of warm weather.

    However, scientists also said that the number of butterflies was in decline(下降) as a whole, and that we might not see the same result the next year.

    Richard Fox, who works for Butterfly Conservation, said, “UK butterflies are in long-term decline.Studies have been done since the 1970s.They show that UK butterflies have declined in type and number.”

    He added, “We must halt the long-term decline of these beautiful creatures(生物).The only way is by stopping the damage that has been done to the butterflies' habitats(栖息地) across the UK.”
