Vinegar makes salad, fries and dumplings taste better, and you can even use it to clean your windows. And now, according to scientists, it may even the planet’s population survive climate change.
Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) in Japan found that growing plants in vinegar makes them more resistant to droughts. This could mean that in the future, worries about climate change affecting the world’s supply of food will be much lower. The discovery was made after the researchers studied the Arabidopsis, a plant known for its ability to survive in dry weather. It was found that when the plant was placed in drought-like conditions, it produced a chemical called acetate（醋酸盐）—the main component of vinegar.
After discovering this, the scientists experimented further by adding acetate to the soil of other plants, before they stopped giving them water completely. After leaving the plants for 14 days, they found that the ones treated with acetate had survived, while the untreated plants had dried up and died.
It’s hoped that this simple method of survival could soon be used to help farmers in dry countries keep their crops alive. "In the experiment, we targeted the staple foods of the world—rice, wheat and maize—and the basic plant of breeding species, rapeseed（油菜籽）," Jong Myong Kim, co-author of the study, told Popular Science magazine.
Kim also told the magazine he’s already been in touch with people all over the world who are interested in trying this simple and cost-effective method out for themselves from flower growing companies to amateur gardeners. Although at this point keeping thirsty plants alive isn’t as easy as just pouring vinegar over them, Kim said he and his team are working on making the process as simple as possible. "Now we are trying to cooperate with some farmers, and also some companies, to make a method to apply this system, "he said. And for those of us who always forget to asr neighbors to water our plants when we go away, hopefully this means the end of returning home from a trip to find our favorite flowers have died.

Pollution’s great effects on the environment have become more obvious in recent years, leading to a movement to promote energy efficiency（效率）,less reliance on fossil（化石) fuels, and a reduction in air and water pollution. Most scientists agree that such changes are necessary to protect our environment from further harm.
The construction industry consumes a large quantity of energy and resources and creates a huge amount of pollution. In the United States, building and development account for 39% of the country’s total energy use, 12% of total water consumption,68% of total electricity consumption and 38% of carbon dioxide emissions（二氧化碳排放）, according to the Environment Protection Agency.
Green buildings use less energy, water, create less waste, and are healthier to live, work, and go to school in than standard buildings. Builders of green buildings use techniques that use resources more efficiently during the entire building cycle—construction, restoration, operation, maintenance（维护）and demolition（拆毁）—than those who construct more regular buildings.
The environmental benefits of building green include the protection of ecosystems（生态系统）and biodiversity, improved air and water quality, less waste flowing into streams, and the protection of natural resources. Green buildings can also result in lower operating costs because they typically use less energy and fewer materials and improve indoor air quality, improving the health of people who live in such buildings.
The process of building green includes technical and artistic planning with nature protection in mind. Building designs often reflect the surrounding environment and natural resources and use renewable building materials such as bamboo and straw. In addition, recycled resources found locally are used for green buildings, reducing the cost and air pollution associated with transporting materials over long distances.
Careful site selection is important to minimize（最小化）human impact on the surrounding environment. For example, placing a structure in an area that allows it to take advantage of cool breezes（微风）and sunlight can reduce energy use and expenses. More energy and expense are needed for larger buildings as well, so it is important to build small.
Green roofs are another feature of green houses that reduce energy use and cost. These roofs are partly or completely covered with plants, which helps to keep heating and cooling costs, prevent water running off and deal with pollutants.
Other features of green buildings often include energy and water conservation, recycling, and waste reduction. In addition, renewable energy sources such as solar power, hydropower（水能）and wind power are used for heat and electricity, which greatly reduces costs and decreases the impact on the environment.
1.What is the text mainly about?
A. The necessity of promoting energy efficiency.
B. The process of building green buildings.
C. The benefits and features of green buildings.
D. Green buildings effects on the environment.
2.According to the text, green buildings refer to the buildings that______.
A. produce no waste
B. only use clean energy
C. are made of recycled materials
D. use energy and resources more efficiently
3.Which of the following statements is TRUE about green buildings?
A. They rely on fossil fuels and solar power for heat and electricity.
B. Small buildings are less efficient in energy use than larger ones.
C. The ecosystem has to be considered when building a green building.
D. They are difficult to maintain and thus need more operating costs.
4.Why are green roofs used ?
A. They fit the surrounding environment well
B. They are cheaper than other kinds of roofs
C. They can keep natural water for use in everyday life
D. They can help to control the temperature in the building well

A new “smart bin” could mean the end of environment-conscious families spending hours sorting tins, cartons, bottles, and cardboard for recycling.
The invention, which can help sort rubbish into recycling categories without needing people to operate. It is being trialed in Poland and is set to go on sale in UK within a few years.
The bin, designed by start-up company Bin.E, recognizes different type of waste via a system positioned inside the bin which uses sensors, image recognition and artificial intelligence. Once waste is placed inside, the camera and sensor identify its type and place it in one of the smaller bins. Then it compresses the waste so it occupies less space.
It is thought that the bin could be stocked by department stores such as John Lewis, which said it is introducing more new hi-tech recycling bins. Matt Thomas, a buyer at John Lewis, gave us the reason, “We’ve recently seen a jump in specialist bins sales, with a 25 percent increase in the last few months alone. We have noticed our customers are becoming more and more focused on sustainability. In response to this demand, we are really excited to introduce a smart bin this autumn/winter season-designed to make recycling more efficient and functional for the everyday home."
Bin. E’s official release on the market will take place in 2018. However, at first only a larger version designed for offices will be available. The office bin will sell at ￡ 430 while customers will need to pay a ￡ 107 subscription fee for an accompanying smartphone app, which hooks them up with collection services. A spokesman at Bin. E said that home version of the bin will be cheaper and will not include a monthly payment.
They added: “After the office version, we plan to create an outdoor version and later the home version. We decided to go for the outdoor version for public areas first because it is more difficult to organize an efficient waste segregating system than in our homes.”
1.What do we know about about a new “smart bin” from the first paragraph?
A. It wortomatically.
B. It has been used widely.
C. It is easy to operate.
D. It is very expensive.
2.What does the underlined word “it” in Paragraph 2 refer to?
A. The waste. B. The camera.
C. The bin. D. The sensor.
3.Why is John Lewis introducing more new hi-tech recycling bins?
A. To change people’s behaviour,
B. To satisfy increasing demands.
C. To popularize new technology.
D. To make them more famous.
4.Where will the first version of new “smart bin” be used according to Bin. E’s official?
A. At home. B. In the supermarket.
C. In the open air. D. In the office.
