1 . Used electronics are piing up fast: they are filling up landfills with dangerous pieces of waste. Some e-waste is relatively large, such as air conditioners; other e-waste is more unnoticed, such as smart labels that contain disposable batteries and other equipment.

“It’s these small batteries that are big problems,” says University of California, Irvine, public health scientist Dele Ogunseitan, who is a green technology researcher and adviser for major tech companies and was not involved in developing the battery. “Nobody really pays attention to where they end up.” Researchers at the Cellulose & Wood Materials Laboratory at the Swiss Federal Laboratories for Materials Science and Technology are working to address this problem. Their new paper describes a water-activated paper battery developed from environmentally friendly materials that could eventually present a sustainable alternative to the more harmful batteries common in low-power devices.

The paper battery has the same key components as standard batteries but packages them differently. Like a typical chemical battery, it has a positively charged side and a negatively charged side. A traditional battery’s components are covered in plastic and metal; in the new battery, however, the positively and negatively charged sides are inks printed onto the front and back of a piece of paper. That paper is filled with salt, which dissolves (溶解) when the paper becomes wet. When the paper is dry, the battery is shelf-stable. Once the paper is wet, the battery starts working within 20 seconds. The new battery’s operating performance declines as the paper dries. When the scientists rewet the paper during testing, the battery regained function and lasted an hour before beginning to dry out again.

That future may not be so far off. It is hard to predict a time line for manufacturing such items at scale, but the head of the study says he is in contact with potential industry partners and believes these batteries could make their way into products within the next two to five years.

3 . All Ric O Barry wanted was to stop the dolphin-killing, so he headed to this seaside Japanese town, Taiji. The American activist, who is the star of a new award-winning documentary that portrays the dolphin-killing here, got an unwelcome reception when he showed up here this week for the start of the annual hunt.

His movie, The Cove (海豚湾), directed by National Geographic photographer Louie Psihoyos, was released in the United States a month ago but has not yet to come out in Japan.

Scenes in the film, some of which were shot secretly, show fishermen banging on metal poles stuck in the water to create a wall of sound that scares the dolphins, which have supersensitive sonar (声呐系统) , and sends them fleeing into a cove.

There, the fishermen sometimes pick a few to be sold for aquarium shows, for as much as $150, 000. They kill the others, spearing the animals repeatedly until the water turns red. The meat from one dolphin is worth about 50, 000 yen, and is sold at supermarkets across Japan.

Greenpeace and other groups have tried to stop the hunt for years. Activists hope The Cove will bring the issue to more people internationally, and eventually in Japan.

Already, the Australian town of Broome dropped its 28-year sister-city relationship with Taiji last month, partly because of the movie.

“Some regions have a tradition of eating dolphin meat,” said fisheries official Toshinori Uoya. “Dolphin-killing may be negative for our international image, but it is not something orders can stop.”

The town government in Taiji, which has made whales and dolphins its trademark, refused to comment about The Cove, or the growing international criticism against dolphin-killing.

Many in Taiji take the dolphin hunt for granted as part of everyday life. They are defensive about The Cove, seeing themselves as powerless victims of overseas pressure to end a simple and honest way of making a living.

C．Attacking those against dolphin-killing.

D．Feeling guilty for killing dolphins.

4. What can we infer from the passage?

A．The Cove has not influenced Japan’s international image.

B．The Cove has brought international attention to dolphin-killing.

C．Taiji’s dolphin-killing industry has been seriously damaged.

D．Many people in Japan have seen The Cove in the cinema.

4 . Man has______ways of showing his love to nature. He says he loves it, although he often______its beauty. While walking through the woods, how many times have we picked flowers, planted roots and all? Then later, as the______wither(枯萎), we throw them away. That’s one of the reasons ____many kinds of plants and flowers have become rare. Or have you______wondered where all the thousands of New Year trees come from and_____ happens to them once the______are over?

Man destroys nature by polluting the air. That’s probably the greatest danger_____our lives. The smoke from factories and______from cars and trucks do not harm only the surrounding vegetation(植被), it ____our health, too.Man pollutes rivers, seas and oceans. Just think of the______fish that die by the thousands because of polluted waters.

Biologists have______that all kinds of wild life are______in the areas where they live. Even the wolf, which we______dangerous and “bad”, plays an important role in nature. Here is an interesting example. There is a large______in one of the Great Lakes between Canada and the US. Early in this century many wild deer invaded(涌入) the island. Nobody knows how they______there.

The deer multiplied(繁殖) until there were as many as 40,000 on the island. They destroyed ____of the vegetation on it. Finally as they couldn’t find enough______they began to starve and die. Then came the wolf:_______knows how wolves got to the island, but they______. The wolves killed those deer that were easiest to catch—the sick, the weak and the old. So only the strong and the healthy animals were left. The island become green once again and there was enough food for the deer that were left.

5 . Alternative Sources of Energy

The world's number one energy source is not man-made. It is much bigger than anything that Man could ever dream of designing or manufacturing, and in fact produces all the energy needs of everybody on Earth.    1    . Apart from it, other energy sources are being exploited by Man to facilitate the development of the modern civilization.

Solar Energy

Solar energy is a simple and already familiar source of more direct renewable energy production. Its use is on the increase as technology improves.    2    . In India there are plans to power 100,000 villages and install 500,000 solar powered telephones. During the course of one year, Europe receives approximately 1000-kilowatt hours of solar energy each square meter.

Water Energy

Water power is used in countries that have a lot of natural rivers and streams.

    3    , because in order to generate hydroelectric power, engineers must first build a dam to block a river and create a reservoir. Power is generated as the water flow from reservoirs is directed to turn turbines and electric generators.

Wind Energy.

    4    . Many countries have also traditionally used wind as a source of power by building windmills. Some windmills even have been used for more than a century, but there has been a significant increase since the 1970s. They are already a familiar sight in Netherlands, Denmark and on windy islands such as Las Palmas in the Canary Islands.

Of course there are many other alternative sources of energy (geothermal power, tidal power, etc.), which are currently being researched and used in countries around the world. These sources often create less pollution than traditional sources of power and are becoming more economical to use as technology improves.    5    .

A．Solar energy is said to keep down the costs of maintenance and energy.

B．It is happening in both developed countries and emerging economies like India.

C．The best source of energy is wind energy.

D．They are the logical choice towards a more environmentally conscious planet.

E．That energy source is by all means the Sun.

F．Another form of energy with us for centuries is the use of wind power.

G．Some environmentalists claim that this type of power can be hazardous to local ecosystems.

6 . 语法填空

Each year     1    (thousand) of tourists visit the polar regions of the Arctic and Antarctica. But the increasing number of people traveling to the ends of the Earth can have     2    negative effect on fragile ecosystems. Should tourists     3    (allow) to visit polar regions?

About 40,000 tourists visit Antarctica each year. More than five million travel to the Arctic and sub-Arctic. Transporting tourists to the regions    4    (increase) ship and airplane traffic, adding to the risk of pollution, oil spills, and other     5    (environment) damage. Because the places where wildlife is accessible     6    (be) few in number, tourist traffic can become concentrated in specific areas,     7     (put)Arctic vegetation(植被) at risk.

Others say that access     8    these very special parts of the world should not be restricted to only researchers and scientists. Polar tourism allows people to develop deep     9    （person） connections with polar regions. “Those     10    travel to the Arctic or Antarctica often become cheerleaders for supporting those places.” Jim Sano, vice president for travel and conservation at World Wildlife Fund, told TFK.
