6 . When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making.
After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine.
The task John set for himself was to remove harmful substances from some sludge (污泥). First he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge.
He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water.
Over the years, John has taken on many big jobs. He developed a greenhouse — like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China.
“Ecological design” is the name John gives to what he does. “Life on Earth is kind of a box of spare parts for the inventor,” he says. “You put organisms in new relationships and observe what’s happening. Then you let these new systems develop their own ways to self-repair.”

9 . It is often said that you can’t have too many friends. But it seems that there is a natural limit to the number of people we stay in touch with. A study found that when we make new friends, by starting a new job or going to university, we downgrade or even drop old ones. And while the friends may change, the number stays almost the same.
Oxford University researcher Felix Reed-Tsochas asked 24 students in the final months of school to list all their friends and relatives and say how close to them they were. The pupils filled in the questionnaire (问卷) twice more after starting work or going to university. They were also given free mobile phones and agreed that researchers could use their bills to work out who they called, when and for how long.
Putting the two pieces of information together showed, unsurprisingly, that most people have a small circle of close friends, who they spend most of their time talking to. This inner circle is surrounded by group after group of ever more distant friends. As the volunteers’ lives changed, this overall pattern, including the number of best friends, remained almost the same, meaning that some close friends from childhood were dropped or downgraded as new friendships were built.
Dr Reed-Tsochas said, “Maybe my best friend is no longer the same person but the amount of time I allocate (分配) to my best friend is still the same.” He added that this finding suggests that even with the coming of modern technology we are only capable of forming a limited number of true friendships.
Chester University researcher Dr Sam Roberts said, “Our results are likely to reflect limitations in the ability of humans to keep emotionally close relationships both because of limited time and because the emotional capital (情绪资本) that individuals can allocate between family members and friends is limited.”
1. Which is a method Dr Reed-Tsochas used in his study?| A．Checking the volunteers’ call records. |
| B．Learning about the volunteers’ hobbies. |
| C．Tracking the volunteers’ job performance. |
| D．Interviewing the volunteers’ schoolmates. |
| A．One’s attitude to friendships remains the same. |
| B．People attach great importance to friendships. |
| C．People rarely drop their old friends to make new ones. |
| D．The number of one’s best friends doesn’t change much. |
| A．To add background information. |
| B．To give a possible explanation. |
| C．To offer some suggestions. |
| D．To introduce a new topic. |
