1 . The Tibet autonomous region has placed nearly half its land area under the strictest ecological supervision (监督).It was announced at an annual meeting of the regional People's Congress, which kicked off on Wednesday.
The ecological protection area, which covers more than 539,000 square kilometers, makes up 45 percent of the region's area, and 22 ecological reserves have been built and are operational.
According to the government work report, the rate of days with good air quality in Tibet's cities has reached 99.4 percent, and all the region's drinking water sources have met applicable standards.
The report also said that the number of Tibetan antelope (羚)in the region has risen to more than 200,000, wildlife species to 1,072 and black-necked cranes to more than 8,000. Five rare new species have been discovered in recent years. The region has spent 12.2 billion yuan ($1.9 billion) on ecological protection projects in recent years. Five cities and three counties have been named as national-level ecologically civilized model cities and counties, and more rural residents have benefited financially by undertaking part-time ecological protection work.
More advanced monitoring facilities have been in place in the reserve, with more ecological protection inspectors employed to undertake protection work. The professional ecological inspectors are provided with basic tools such as motorcycles, telescopes and paging receivers, and they provide feedback regularly. Professional inspectors also receive one week of training every year from professors at Tibet University.
Kunsang Darje, a railway maintenance worker in Nagchu, said that apart from maintaining the railway and highway, he also collects trash along the section with his colleagues. “The place I work is in a no-man's land, and I think it's very important to protect the animals there without affecting them with human activities, and we are also bound to take responsibility there," he said.

Popping food into the microwave for a couple of minutes may seem harmless, and Europe's stock of these quick-cooking ovens give out as much carbon as nearly 7 million cars, a new study has found, and the problem is growing. With costs falling and kitchen appliances becoming frequently updated, owners are throwing many microwave after an average of eight years. This is pushing sales of new microwaves which are expected to reach 135 million annually in the EU by the end of the decade.
A study by the University of Manchester worked out the emissions of carbon dioxide-the main greenhouse gas responsible for climate change - at every stage of microwaves, from production to waste disposal (处理). “It is electricity consumption by microwaves that has the biggest impact on the environment,” say the authors, who also calculate that the emissions from using 19 microwaves over a year are the same as those from a car. According to the same study, efforts to reduce consumption should focus on improving consumer awareness and behaviour to use appliances more efficiently. For example, electricity consumption by microwaves can be reduced by adjusting the time of cooking to the type of food.”
However,David Reay, professor of carbon management argues that,although microwaves use a great deal of energy, their emissions are minor compared to those from cars. In the UK alone, there are around 30 million cars. These cars emit more than all the emissions from microwaves in the EU. Backing this up, recent data show that passenger cars in the UK emitted 69 million tons of carbon dioxide in 2015. This is 10 times the amount this new microwave oven study estimates for annual emissions for all the microwave ovens in the whole of the EU. Further, the energy used by microwaves is lower than any other form of cooking. Among common kitchen appliances used for cooking, microwaves are the most energy efficient, followed by a stove and finally a standard oven. Thus,rising microwave sales could be seen as a positive thing.

High on the Qinghai-Tibet Plateau
6 . Surrounded by the sea off the coast in Mid-Norway, lies an island called Myken. This small island has about ten permanent residents, and for more than 50 years has been supplied with electricity via a 32-kilometer undersea cable (电缆). A break that appeared in the cable last autumn resulted in two months without power, so the island community started looking into a better way of sourcing their electricity.
“Myken is far out at sea, so as far as possible it should be taking care of things itself,” says Kyrre Sundseth, who is a hydrogen (氢) researcher in Norway and also the project manager for Myken’s energy project. “This is why we want Myken to become entirely self-sufficient in energy. It is also important to take the environment into consideration,” he says.
Much points to the idea that the solution may lie in a Hydrogen plant, specifically tailored for small islands. The “raw materials” for hydrogen production come from nature itself in the form of the sun and wind. Researchers have calculated that energy costs will be lower by using hydrogen production than the undersea cable option. And it is possible to store energy in the form of hydrogen for longer periods. This means that supplies will not have to rely on a lot of expensive batteries or external energy sources, even during periods when the sun isn’t shining, or the wind isn’t blowing.
The Myken project has attracted several technology companies. They are currently working on a pilot project. The pilot involves experiments on the feasibility (可行性) of the hydrogen system in which electricity is generated from solar and wind sources. The electricity can be used immediately, but during periods when all the energy generated is not required, the spare energy can be used to split seawater into hydrogen and oxygen. The hydrogen can be stored in a tank, and used later to generate electricity. The pilot will help researchers know more about how effectively the system will work in the hydrogen plant. Since the island has a distillery (酿酒厂), where the distillation (蒸馏) process relies on energy, a hydrogen plant on Myken offers an even greater environmental benefit. Spare heat from the hydrogen system can also be used for the heating part in the distillation process.
“In Norway alone there are about 300 island inhabited all year round by small populations,” says Kyrre Sundseth. “All of these islands may be candidates for using this technology. In global terms we’re talking about 10,000 similar islands.”

7 . Finding a mountain goat resting high on a cliff(悬崖) might thrill many of the millions of tourists who visit Wyoming’s Grand Teton National Park every year, but park officials say it might be time for the bearded animals to go.
The problem, according to the park, is that Grand Teton’s 100 or so mountain goats threaten about 80 bighorn sheep. The bighorn sheep numbered as many as 125 just a few years ago. The strong goats spread disease and compete with bighorn sheep for food. Unlike small-sized bighorn sheep, Grand Teton’s mountain goats aren’t native to the park. They were introduced to the park in the 1960s.
Grand Teton spokeswoman Denise Germann said, “We’ve got a management responsibility to protect the native species. After hearing from the public on the proposal (建议) in January, park officials expect to decide as soon as mid-February on what to do about the mountain goats.”
The goats are reproducing rapidly. Now might be the best time to reduce the animals before they’re too many to bring under control, according to the Park Service.
One wildlife biologist who studies bighorn sheep praised the proposal. Mountain goats’ original habitat is nowhere close to where they’ve been introduced in the U.S. to provide hunting opportunities, said Rob Roy Ramey II, with Nederland, Colorado-based Wildlife Science International, Inc.
Wildlife managers should get rid of mountain goats not only in Grand Teton but elsewhere to help struggling bighorn sheep, Ramey said. “Unfortunately, state wildlife agencies sell nonnative wildlife viewing opportunities to the public,” Ramey said. “This is not a zoo in the wilderness. It should really be for native wildlife.”

8 . We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.
So what's the solution（解决方案）? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.

| C．They cost more to use at home. | D．They go out of style quickly. |
| A．To reduce the cost of minerals. |
| B．To test the life cycle of a product. |
| C．To update consumers on new technology. |
| D．To find out electricity consumption of the devices. |
| A．The box-set TV. | B．The tablet. |
| C．The LCD TV. | D．The desktop computer. |
| A．Stop using them. | B．Take them apart. |
| C．Upgrade them. | D．Recycle them. |
