In the 1960s Professor Bolin predicted that the “greenhouse effect”, caused by an increase in the amount of carbon dioxide (CO₂) in the atmosphere, would lead to important changes in the Earth’s climate. At the time his prediction were regarded as science fiction. But it is now gradually agreed that the amount of carbon dioxide in the atmosphere will double from 0.03% to 0.06% in the next 50 years and that temperatures worldwide will rise by 2°Celsius.

Although a temperature rise of 2°may not seem significant, the local effects may be much greater: in polar regions a rise of 10°by 2025 is expected and in Northern Europe a rise of 4°. Indeed the first effects were expected to be felt before the end of the 20^th century,

But how does the “greenhouse effect”operate and why should such a tiny proportion（比例）of CO₂ have such a harmful effect? When living creatures breathe out or when things are burned, CO₂ enters the atmosphere. Until recently all of this was absorbed by plants, which converted it back into oxygen.

However, the balance of nature has been disturbed. In power stations, in factories and in our cars, we are burning more and more fossil fuels( coal, oil and natural gas ) and this produces huge quantities of CO₂---18 billion tons of it enter the atmosphere every year. Added to this, the destruction of forests means that less CO₂ can be converted into oxygen by plants. So, the amount of CO₂ in the atmosphere is increasing every year.

1.Which of the following statements is true according to the passage?

2.The amount of CO₂ in the atmosphere is increasing every year because________.

3.The “greenhouse effect”refers to ________

4.The underlined word“operate”in the third paragraph most probably means“________”.

But how does the “greenhouse effect” operate and why should such a tiny proportion (比例) of CO2 have such a harmful effect? When living creatures breathe out or when things are burned, CO2 enters the atmosphere. Until recently all of this was absorbed by plants, which converted (转化) it back into oxygen.

However, the balance of nature has been disturbed. In power stations, in factories and in our cars, we are burning more and more fossil fuels (coal, oil and natural gas) and this produces huge quantities of CO2—18 billion tons of it enter the atmosphere every year.

Many experts are calling the growing problem of global waste a worldwide health crisis in since pollution from trash is not only harming the world’s oceans, air and soil but also endangering people’s health as well as the livelihood of all living creatures.

Reduce, reuse, recycle

Such a dilemma raises the question, is there a more responsible way of dealing with trash? Fortunately, there is. 1.One example of this is what’s often called the three Rs: reduce, reuse, recycle. Reducing the use of plastic containers as well as reusing and recycling bottles and cans decreases the amount of garbage being sent to landfills. As a result, less money is spent on waste management, and countries’ financial burdens are significantly relieved. Such positive effects on an economy are known as a circular economy.

Circular economy

Traditionally, manufacturers would make a product to be used and disposed of by consumers. This linear (直线型的) model of production offered no help in the fight against global waste. 2..

Once a product’s value is exhausted, the materials are recycled and returned to manufacturers. The outcome is less waste. One large-scale example of this is happening on the island of Taiwan.

3.

In 1997, Taiwan established its signature 4-in-1 Recycling Program, consisting of communities, government cleaning teams, recycling companies and the Recycling Fund. Residents separate their recyclable waste. The local government collection teams collect it.4.. Importers and manufacturers who are responsible for the recyclable products pay a fee into the Recycling Fund. The Recycling Fund is an essential aspect of the program used to subsidize (补贴) the recycling disposal system, support education and research and development as well as finance recycling efforts in the future.

Turning garbage into gold

By following a circular system, more products than ever are being manufactured using recycled materials. Environmentally-friendly decisions like these help to conserve natural resources, reduce pollution, save landfill space and even create new job opportunities. 5..

A.Practices in Taiwan

B.4-in-1 Recycling Program

C.Recycling can truly turn garbage into gold

D.Living a zero-waste lifestyle is the way to go

E.Alternatively, a circular economy was introduced

F.The recyclable waste is recycled in many local factories

G.Recycling companies buy waste materials from them to make profits
