Lin Shuiqing: Good morning, everyone. First I am talking to you today about the way vast areas of the world are damaged by chemical waste. Many places have been destroyed and many plants and animals 【小题1】(die). Other types of waste flow into our water, 【小题2】 (kill) river and sea life.

Much sea life is being destroyed by fishing boats as well. These boats catch large numbers of fish without【小题3】 (give) them time to lay eggs. This will result【小题4】a smaller number of fish left for us to eat in the future.

Qian Liwei: Good morning, ladies and gentlemen. Thank you, Ms Lin. That was【小题5】interesting speech. It is clear that you are very concerned about the present situation of our environment. When people think of【小题6】(factory), they think of clouds of dirty smoke or of pipes pouring chemical waste into rivers. People often have this belief 【小题7】development is bad for the environment. What I’m here to say is that   【小题8】 (work) with many environmental consultants, I know that a healthy environment and development should be【小题9】( possibly) at the same time. What we need are better laws【小题10】 (preserve) the environment and still allow our country to grow.

When Peter Sanger and Liang Wu got together, it【小题1】（strike）them that they must be long-lost friends, Both firm advocates in the fight【小题2】air pollution, they believe that if you can't measure it, you can't beat it. That's【小题3】 they founded Green City Solutions: "The solution to quantifiably improve city air."

The invention—the City Tree—act as an air purifier-an interesting【小题4】（add）to urban trees and green spaces. Rooted in science, air pollution can be eaten by the vertical flat-paneled（平面的）"trees"【小题5】（dot）around cities across Europe, while the "trees" also act as seats for pedestrians Sanger and Wu's vision is for a world in which people in cities can live【小题6】（healthy）. They long to create living conditions that allow all people around the world to permanently have cleaner air【小题7】（breathe）.

Using remote technology, the City Tree combines【小题8】air-purifying feature of moss with remote technology to increase the air flow through the "trees". This allows them to "suck up" and clean more air than normal, and the amount they filter can be increased【小题9】（depend）on pollution levels at different times of day.

The German green-tech start-up is now funded by the European Commission to set up a City Tree network of 15 brand new units and test it in a【小题10】（science）way in Berlin's pollution hotspots next year.

People are having a debate about whether 【小题1】 (develop) the economy or protect the environment. 【小题2】 Lin Shuiqing’s opinion, 【小题3】 is our duty to cut back on 【小题4】 (produce) and reduce the quantities of things we make and buy while Qian Liwei thinks that businessmen are not greedy and they don’t hide from their 【小题5】(responsible), either. As far as he is concerned, the people 【小题6】 (operate) these factories are 【小题7】 (deep) concerned about the environment, and should 【小题8】 (give) more credit. As 【小题9】 matter of fact, many people are willing to pay a little higher price for things 【小题10】 are friendly to the environment.
