What will the house of the future look like? Architects (建筑师) believe that there are all possibilities. The only thing for sure is that the house will be as green as possible.
The tree house
Many architects in the world would like to build a “tree house.” Like a leaf, the surface (表面) of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root” of the house is deep under the ground.
The lizard (蜥蜴) house
Like a lizard, changing color with the weather is the most important design of a lizard house. When it’s in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.
Meals at home
It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.
Learning from the past
Looking to the future isn’t the only way to be green. Sometimes, ancient techniques (古老的技术) can also help cut down energy use. For example, a chimney can be a useful air conditioner because it is easier for hot air to flow out at the chimney.
【小题1】We can heat water, produce electricity or create fresh air for the home _________.

Many cities around the world today are heavily polluted. Products (产品) arc not produced in a "green" way and people haven't realized the importance of buying and using environmentally-friendly products. These lead to the pollution problem. One result is that millions of tons of waste like glass, paper and plastics is produced (生产). The waste problem is difficult to deal with.

However, today, more and more people are choosing “green” and expecting that the products they buy should be safe for the environment. Before they buy a product, they ask questions like these: “Will this soap be bad for the environment” “Can this metal container be reused or can it only be used once?”

Over 20,000 people took part in a web survey (调查) on buying environmentally-friendly products. Among them, 8129 people say that they now consider the environmental safety of a product before they buy it. That is to say, companies must change the way they make and sell their products to make sure that the products are “green”.

A few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarket products carry labels to show that they are green. Some companies have made the clean and safe products their main selling point in advertisements.

The growing need for a safer and cleaner environment is making companies rethink how they do business. The public will no longer accept the old idea of “buy it, use it, throw it away, and forget it”. As a result, the companies have to take action.

1.Is it easy to deal with the waste problem?

2.What do more and more people consider before they buy products?

3.In the survey, how many people prefer green products in the supermarket now?

4.Is it possible or impossible to get green products in the supermarket now?

5.Why do the companies have to rethink how to do business and take action?

If you are like me, your parents may also make you take part in after-class activities. And you always listen to them. But we are older now. We should start to do what we like. My parents used to make me go to activities like basketball, swimming, choir (唱诗班), Chinese and violin lessons. But I didn’t like some of these things.
This year, I stopped going to some activities. I stopped playing basketball and swimming because I don’t like them anymore. I stopped going to Chinese lessons. I can learn Chinese at home. I only take part in school band, after-school Spanish and violin lessons. My mother says I don’t do enough sports. “I walk home 2 miles (3.2km) every day. It’s a sport.” I tell her. Walking is a sport. Don’t you think so?
