1 . Every summer, the Serengeti plains (平原) of Africa are worth visiting. Millions of wild animals begin their 1,800-mile journey northwards on their annual migratory (迁移的) route.
In the month of November, polar bears in their thousands cross the Canadian Arctic, as they head towards the ice sheets of Hudson Bay. The sea ice that forms every winter is the key to the bear’s managing to exist, for here they hunt for seals (海豹).
The Great Bustard, one of the heaviest flying birds, migrates each year across Europe and Asia to its wintering grounds. Unluckily, these and other migratory animals are in danger from human activity.
We have written several articles on climate change and the effect of rising ocean temperatures. Since 1979, ice sheets in the Arctic have gone down by 30 percent. What does this mean for polar bears? They are forced to stay on land for longer periods of time, which delays their search for food. As a result, bears today are 60 pounds lighter than what they were. Besides, smaller bears also produce weaker babies, and their chances of survival are at risk. In the plains of Africa, migratory animals like gazelles are traveling long distances for food, just to avoid falling prey (牺牲品) to humans who hunt them.
In an unusual step, experts from 120 countries have agreed to protect 31 migratory mammals, fish and birds. The United Nation’s 11th annual Conservation of Migratory Species of Wild Animals (CMS) was held in Quito, Ecuador. For the first time, 900 experts attended the conference, and the enthusiastic support shows the world is united in conservation (保护) efforts.
What does getting on a protected list mean? Countries that have signed the agreement will be required to pass laws locally and work with other countries that fall within the animal’s migratory path. Only one animal did not make the list. The African lion was rejected (拒绝) for lack of information of the countries where it lives.

2 . “Developed and developing nations can learn from each other seeking a low-carbon economy. In terms of energy saving and green economy, China doesn’t lag behind developed nations,” said Zhou Changyi, director of the energy saving department of the Ministry of Industry and Information Technology.
“While we can learn many aspects from developed nations, they also should learn something from us, such as water conservation,” Zhou said in a speech during the new Path of China’s Industrialization forum at the ongoing China International Industry Fair.
He said industrialized nations and China are dealing with different issues to fight climate change. The United Kingdom, for example, is concerned about transport, buildings and new energy in reducing carbon emissions. For China, the most urgent task is how to realize new type of industrialization and avoid mistakes that other countries made when they industrialized.
Swiss power and automation technology group ABB called for a stronger focus on product life-cycle assessment, or LCA, which is used to study the environmental impact of a product from the research and manufacturing stage through its usage and recycling.
Tobias Becker, head of ABB’s process automation division for North Asia and China, said LCA is an effective tool in helping manufacturing industries to reduce carbon emissions.
LCA shows that industrial customers should focus on a product’s environmental impact throughout its life-cycle instead of on its initial investment.
Richard Hausmann, North East Asia CEO of Siemens, said, “The color of future industrialization is green. ”
The Germany company recently announces that it wants to receive orders worth more than 6 billion Euros ( US 8. 8 billion) for intelligent power networks, Smart Grid, over the next five years. Siemens has set a 20 percent market share target for the global smart grid business.
A smart grid delivers electricity from suppliers to consumers using digital technology, advanced sensors specialized computers that save energy, reduce costs and increase reliability. The United States and China are considered the two biggest markets for smart grid.

3 . Not only does the use of plastic water bottles hurt your wallet, it also increases pollution and wastes energy and water. Only 23% of all plastic in America ends up in a recycling bin, meaning over $ 1 billion worth of plastic is treated as rubbish a year. Recently, Skipping Rocks Lab has invented a kind of water bottle called Ooho.
It is a convenient, clear water bottle that can either be drunken or eaten. To drink it, you can either peel off the membrane (薄膜) or tear a hole in the membrane with your teeth to pour the water into your mouth. To eat it, you simply put the whole bottle in your mouth. One problem the scientists have run into is how to ship large amounts of Ooho bubbles(水泡) without arriving with a very wet truck. However, they have attempted to package units of individual bubbles together inside a larger and thicker membrane. It is targeting large outdoor events, such as marathons, music festivals, and sporting events, where tons of plastic bottles are used, and frequently left behind as litter. And too much plastic is sure to do harm to the environment, which could account for their purpose of such a new invention.
The team has been working for the past two years to develop the technology and materials needed to produce Ooho; they have recently applied a patent for their new advancements. The price for an individual bubble or a unit of bubbles has not been set yet, but they cost about two cents to create a unit, which is cheaper than plastic bottles. It has appeared at events in London, San Francisco, Boston, at conferences, festivals, and so on.
Ooho is catching many people’s attention and has raised over $ 1 million and gained 1,000 investors in only three days. It is mostly being sold at events at the moment to keep the consumer’s interest while the production machine is getting up and running. It is quickly making a rise,so keep an eye out this year for these bottles of the future.

4 . Colorado officials will stick to a plan to kill some mountain lions and bears to support the state’s dropping mule deer (长耳鹿) population.
Wednesday’s vote permits organizations to kill up to 25 black bears and 15 mountain lions per year in the central and western parts of the state. The project will run for three years, to be followed by a six-year study of how deer populations respond to fewer predators(捕食者).
The population of Colorado’s mule deer has suffered a puzzling, years-long drop to about 450,000, which state officials said was about 110,000 fewer than there should be. A 2014 state study tied it to seven causes, including predators, whose number has greatly increased in recent years.
Some experts, however, said the state should focus first on the human-led destruction(破坏) of mule deer habitat(栖息地). “The drop of the mule deer population is obviously not a simple problem with simple causes,” Brian Kurzel, director of the National Wildlife Federation, said. “By far, the greatest problem—the one that I think deserves the most attention in any science-based study—is habitat quantity and quality.”
Kurzel pointed out that the U.S Bureau of Land Management recently agreed to create 15,000 new oil and gas wells somewhere in western Cororado, which was often called “the mule-deer factory”. There, the number of mule deer has fallen to about 30,000 from more than 100,000 in the early 1980s. Though state officials have known oil and gas development affects the population of mule deer, they didn’t go against the plan.
Other causes like building highways, population growth and human activities are also curbing the mule deer population, according to the study.
State Parks and Wildlife officials don’t necessarily disagree. They started a $4.5 million program as a way to gather research for later decisions.
1. Why do Colorado officials want to have so many mountain lions and bears killed?| A．To stop them hurting people. |
| B．To leave more habitat for mule deer. |

| A．Protecting their habitat. | B．Providing enough food for them. |
| C．Reducing the number of their predators. | D．Asking the government to make an effort. |
| A．limiting. | B．ensuring. | C．increasing. | D．protecting. |
| A．Decisions will be made in one year. |
| B．Habitat loss is the main cause of the drop. |
| C．Human activities aren’t responsible for the drop. |
| D．It’s too early to say what exactly caused the drop. |
