1 . 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.”

2 . Turning soil, pulling weeds, and harvesting cabbage sound like tough work for middle and high school kids. And at first it is, says Abby Jaramillo, who with another teacher started Urban Sprouts, a school garden program at four low-income schools. The program aims to help students develop science skills, environmental awareness, and healthy lifestyles.

Jaramillo’s students live in neighborhoods where fresh food and green space are not easy to find and fast food restaurants outnumber grocery stores. “The kids literally come to school with bags of snacks and large bottles of soft drinks,” she says. “They come to us thinking vegetables are awful, dirt is awful, insects are awful.” Though some are initially scared of the insects and turned off by the dirt, most are eager to try something new.

Urban Sprouts’ classes, at two middle schools and two high schools, include hands-on experiments such as soil testing, flower-and-seed dissection, tastings of fresh or dried produce, and work in the garden. Several times a year, students cook the vegetables they grow, and they occasionally make salads for their entire schools.

Program evaluations show that kids eat more vegetables as a result of the classes. “We have students who say they went home and talked to their parents and now they’re eating differently,” Jaramillo says.

She adds that the program’s benefits go beyond nutrition. Some students get so interested in gardening that they bring home seeds to start their own vegetable gardens. Besides, working in the garden seems to have a calming effect on Jaramillo’s special education students, many of whom have emotional control issues. “They get outside,” she says, “and they feel successful.”

1. What do we know about Abby Jaramillo?

A．She used to be a health worker.	B．She grew up in a low-income family.
C．She owns a fast food restaurant.	D．She is an initiator of Urban Sprouts.

3 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

For thousands of years, people have told fables (寓言)     1     (teach) a lesson or to pass on wisdom. Fables were part of the oral tradition of many early cultures, and the well-known Aesop’s fables date to the     2     (six) century, B. C. Yet, the form of the fable still has values today,     3     Rachel Carson says in “A Fable for Tomorrow.”

Carson uses a simple, direct style common to fable. In fact, her style and tone (口吻) are seemingly directed at children. “There was once a town in the heart of America,     4     all life seemed to enjoy peaceful existence with its surroundings,” her fable begins,     5     (borrow) some familiar words from many age-old fables. Behind the simple style, however, is a serious message     6     (intend) for everyone.

    7     (difference) from traditional fables, Carson’s story ends with an accusation instead of a moral. She warns of the environmental dangers facing society, and she teaches that people must take responsibility     8     saving their environment.

The themes of traditional fables often deal with simple truths about everyday life. However, Carson’s theme is a more weighty     9     (warn) about environmental destruction. Carson proves that a simple literal form that has been passed down through the ages can still     10     (employ) today to draw attention to important truths.

4 . An Australian professor is developing a robot to monitor the health of grazing cattle, a development that could bring big changes to a profession that's relied largely on a low-tech approach for decades but is facing a labor shortage.

Salah Sukkarieh, a professor at the University of Sydney, sees robots as necessary given how cattlemen are aging. He is building a four-wheeled robot that will run on solar and electric power. It will use cameras and sensors to monitor the animals. A computer system will analyze the video to determine whether a cow is sick. Radio tags (标签) on the animals will measure temperature changes. The quality of grassland will be tracked by monitoring the shape, color and texture (质地) of grass. That way, cattlemen will know whether they need to move their cattle to another field for nutrition purposes.

Machines have largely taken over planting, watering and harvesting crops such as com and wheat, but the monitoring of cattle has gone through fewer changes.

For Texas cattleman Pete Bonds, it's increasingly difficult to find workers interested in watching cattle. But Bonds doesn't believe a robot is right for the job. Years of experience in the industry - and failed attempts to use technology - have convinced him that the best way to check cattle is with a man on a horse. Bonds, who bought his first cattle almost 50 years ago, still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick.

Other cattlemen see more promise in robots. Michael Kelsey Paris, vice president of the Oklahoma Cattlemen's Association, said a robot could be extremely useful given rising concerns about cattle theft. Cattle tend to be kept in remote places and their value has risen, making them appealing targets.

1. What is a problem with the cattle-raising industry?

A．Soil pollution.	B．Lack of workers.
C．Aging machines.	D．Low profitability.

2. What will Sukkarieh's robot be able to do?

A．Monitor the quality of grass.	B．Cure the diseased cattle.
C．Move cattle to another field.	D．Predict weather changes.

3. Why does Pete Bonds still hire cowboys to watch cattle?

A．He wants to help them earn a living.	B．He thinks men can do the job better.
C．He is inexperienced in using robots.	D．He enjoys the traditional way of life.

4. How may robots help with cattle watching according to Michael Kelsey?

A．Increase the value of cattle.	B．Bring down the cost of labor.
C．Make the job more appealing.	D．Keep cattle from being stolen.

5 . We live in a town with three beaches. There are two parts less than 10 minutes’ walk from home where neighborhood children gather to play. However, what my children want to do after school is pick up a screen — any screen — and stare at it for hours. They are not alone. Today’s children spend an average of four and a half hours a day looking at screens, split between watching television and using the Internet.

In the past few years, an increasing number of people and organisations have begun coming up with plans to counter this trend. A couple of years ago film-maker David Bond realised that his children, then aged five and three, were attached to screens to the point where he was able to say “chocolate” into his three-year-old son’s ear without getting a response. He realised that something needed to change, and, being a London media type, appointed himself “marketing director from Nature”. He documented his journey as he set about treating nature as a brand to be marketed to young people. The result was Project Wild Thing, a film which charts the birth of the World Network, a group of organisations with the common goal of getting children out into nature.

“Just five more minutes outdoors can make a difference,” David Bond says. “There is a lot of really interesting evidence which seems to be suggesting that if children are inspired up to the age of seven, then being outdoors will be on habit for life.” His own children have got into the habit of playing outside now: “We just send them out into the garden and tell them not to come back in for a while.”

Summer is upon us. There is an amazing world out there, and it needs our children as much as they need it. Let us get them out and let them play.

1. What is the problem with the author’s children?

A．They often annoy their neighbours.	B．They are tired of doing their homework.

9 . Marvelous Scenic Walks Near London

There are plenty of walking routes in London. If you fancy something a bit more rural, then the green and pleasant land has plenty to offer.

Goring Gap and the Thames Path

If you’re in the mood for a gentle rural walk, the Thames Path is far from boring. The 5-mile footpath follows the curve of the river, winding past wildflower meadows (草地).

Post-walk pub: Pangbourne’s seventeenth-century pub The Swan serves high-end dishes. Bag a table on the riverside or keep toasty by one of its open fires.

Box Hill

To admire this spots rural views, first you’ve got to jump across 17 stepping stones and climb 272 steps to the top of Box Hill, where the path begins. The total distance is 6.8 miles.

Post-walk pub: The cavernous Tree on Box Hill has an attractive menu and huge beer garden, or sample a glass of Juniper Hill at Denbies Winerie.

A South Downs Ridge (山脊)

If you’ve already done the classic Seven Sisters clifftop walk or can’t face all those hills, this is a long but lovely alternative. The route covering 14.3 miles snakes along a ridge and a river valley.

Post-walk pub: There are always 10 real beers at the old-school pub The Wellington.

Chess Valley in the Chilterns

Chess Valley in the Chiltern Hills isn’t home to any chess masters, but it used to produce a kind of water plant. This walk of 4.9 miles follows the river, winding through rolling meadows and woods.

10 . We may weep for the dodo, but could and should we bring this lovely bird back from the dead? De-extinction is the science of restoring lost species and it has been in the news for decades.

The story in modern times began in 1990 when Michael Crichton published his science fiction novel Jurassic Park, in which he imagined a world where scientists were able to bring dinosaurs back to life. Crichton imagined that polymerase chain reaction (PCR) technology could be a way to amplify (放大) tiny quantities of dinosaur DNA and thus build a living embryo.

Sadly, biologists soon realized that DNA in fact breaks down super-fast; even after 100 years, DNA from museum skins of dodos was decayed (腐烂) beyond repair. They could be sequenced (测定序列) using massive computational power, but then only with considerable uncertainty. And even if you capture a DNA sequence, there’s still the problem of how you get living cells to read that sequence and express proteins that make the dinosaur or the dodo.

But why would anyone want to see mammoths, or something like them, roaming (漫游) present-day Siberia? Well, they were undoubtedly amazing beasts. As well as hunting them, our distant ancestors painted their likenesses in caves across Europe. Fascinating as they may be, there's some ecological justification for the project too.

It was this diversity of land surface, broken up by heavy limbs and randomly fertilised by faeces (排泄物), that supported so much flora (植物群). Without the mammoths, that diversity disappeared. Return them and landscapes would once again be with a variety of species, including flowers and bushes.

True, it’s not de-extinction in the sense of bringing a long-dead species back to life. Instead it’s more like making a “dodo” by engineering a modern pigeon, its closest relative, to become huge and flightless. The result would be a big, fatty pigeon that, whether it looked like a dodo or not, would probably fulfil some of its ecological roles.

As a palaeontologist, I would of course love to see living dinosaurs, mammoths and dodos. In some ways, though, I am relieved that the optimistic claims for cloning and genetic technologies have not been borne out. The slowdown gives us time to consider the outcomes—and hopefully avoid some of Michael Crichton’s more fevered imaginings.
