Easter is still a great day for worship, randy in baskets and running around the yard finding eggs, but every year it gets quite a bit worse for bunnies.

And no, not because the kids like to pull their ears. The culprit is climate change, and some researchers found that rising temperatures are having harmful effects on at least five species of rabbit in the US.

Take the Lower Keys March rabbit, for instance. An endangered species that lives in the Lower Florida Keys, this species of cottontail is a great swimmer — it lives on the islands! — but it is already severely affected by development and now by rising levels. According to the Center for Biological Diversity, an ocean level rise of only 0. 6 meters will send these guys jumping to higher ground and a 0.9-meter rise would wipe out their habitat completely.

The snowshoe hare, on the other hand, has a color issue. Most of these rabbits change their fur color from white in the wintertime to brown in the summer, each designed to give them better cover from predators. As the number of days with snow decreases all across the country, however, more and more bunnies are being left in white fur during brown dirt days of both fall and spring, making them an easier mark for predators. Researchers know that the color change is controlled by the number of hours of sunlight, but whether the rabbit will be able to adapt quick enough to survive is a big question. The National Wildlife Federation has reported that hunters have noticed their numbers are already markedly down.

American pikas or rock rabbits, a relative of rabbits and hares, might be the first of these species to go extinct due to climate change. About 7-8 inches long, pikas live high in the cool, damp mountains west of the Rocky Mountains. As global temperatures rise, they would naturally migrate to higher ground — but they already occupy the mountaintops. They can't go any higher. The National Wildlife Federation reports that they might not be able to stand the new temperatures as their habitat beats up.

The volcano rabbit has the same problem. These rabbits live on the slopes of volcanoes in Mexico, and recent studies have shown that the lower range of their habitat has already shifted upward about 700 meters, but there are not suitable plants for them to move higher, so they are stuck in the middle. Scientists are concerned about their populations.

Native to the US, pygmy rabbits weigh less than 1 pound and live in the American West. They are believed to be the smallest rabbits in the world. Their habitats have been destroyed by development. Several populations, such as the Columbia Basin pygmy, almost went extinct and were saved by zoo breeding programs. Pygmy rabbits also rely on winter cover by digging tunnels through the snow to escape predators, but lesser snowfall is leaving them exposed.

All of this gives new meaning to dressing up in a giant bunny costume this Easter.

I am so grateful for the 21-Day Eco challenge hosted by Kindspring. Taking care of our sweet Mother Earth has always been __(1)____ to me in my life and I have taken __(2)____  in my everyday life to recycle, reuse, think about ways to protect our Mother Earth, etc. However, this __(3)____  awoke me even more.

Our Scholars Together community has taken on more than we have before __(4)____  recycling ,using our own china cups and metal water bottles when we go out ,not buying things in __(5)____  containers and having green lunches more consistently, not__(6)____  ,but the biggest change we made was setting a goal of Zero Waste.

We set up more boxes and bins for paper that we could __(7)____  again, recycled every sheet of use-on-both-side paper, plastics, cans ,etc. We also __(8)____  all of our food we cooked or bought ,instead of throwing some away. We really __(9)____  it a challenge. Each day we all saw how little __(10)____ could be in our dustbins. I realized that I had been throwing paper away that could be used on the other __(11)____ or could be recycled, and now I am looking everywhere for __(12)____  that can be used more __(13)____  until recycling time.

The videos offered by Kindspring have been so__(14)____  and useful to us all that I don’t want the Eco challenge to __(15)____ . We will continue to do our part and __(16)____  the news to our family and friends. Next week we are trying some __(17)____  in our local sandwich and sub shops where the kids like to go to see that we can bring our own __(18)____  in, rather than having them put in bags. It is cool to see how the __(19)____  spreads. Thank you Kindspring for __(20)____  the community with daily support and great researched videos and information.

The 1990s saw great changes in the way people communicate. People could send mail without going to the   (1)  , and go shopping without leaving home.   (2)   like email and download became part of people’s vocabulary. The cause of this great change was the   (3)  .

The idea for the Internet began in the early 1960s in   (4)  . The Department of Defense (美国国防部) wanted to   (5)   their computers together in order to   (6)   private information. In 1969, the ARPA net(an early form of the Internet) first connected the   (7)   at four American universities. One computer successfully   (8)   information to another. In 1972, scientists shared ARPA net   (9)   the world. They created a   (10)   to send person-to-person messages using ARPA net. This was the   (11)   of email.

Over the next few years, there was a lot of progress made in the world of computing,   (12)   most people were not using the Internet. Then, in the 1980s, personal computers became more   (13)  . In the early 1990s,   (14)   important things happened:the birth of the World Wide Web in 1991, and the creation of the   (15)   Web browser（浏览器）in 1993.The web made it   (16)   to find information on the Internet, and to move from place to place   (17)   links. The Web and browser made it possible to see information as a website with pictures, sound, and words.

Today,   (18)   of people connect to the Internet to send email, visit websites, or store information on servers.   (19)   are now an important part of our lives and are changing   (20)   we learn, work, shop, and communicate.

  Fatty food, increased use of automobiles and a drop-off in cycling all have contributed to some side effects in China. The   (1)   government figures show roughly one fifth of the population is   (2)  overweight or obese.

  He Yifan weighed 157 kilograms when he arrived at the weight loss clinic two months ago. He says he lived an indulgent(纵容的) life at university and packed on the weight. Then he   (3)  ; he says it’s time to get rid of the kilos and fight off obesity.

  “My friends made   (4)   about me for being fat sometimes,” he said. “But this is more about myself. It’s hard to find a   (5)  , and it’s not good for my   (6)  .”

  Around one in five people are   (7)  or obese in China--more than 250 million people. It’s an   (8)  result of the country’s rapid economic development which has   (9)   a more sedentary (久坐的)lifestyle for many. World Healthy Organization’s China representative Dr Hans Troedsson agrees. “ With unhealthy diets and less   (10)  exercise, it creates this almost boom of obesity that we see in China today,” Troedsson said.

  The staff at the Aimin Weight loss Clinic keeps a   (11)   eye on exercise and diet. They tell He to eat less fatty food and more regulated portions.

  “ When I first came I was really   (12)  , but after a couple of weeks I got   (13)   to it. Now I eat less than the others because I have higher   (14)   for myself, and I want to   (15)   weight faster,” he said.

With diabetes and hypertension(高血压) on the   (16)   , the WHO   (17)   lifestyle diseases are becoming a   (18)   issue for this national’s healthcare system.

 China’s health officials say they want more people to follow in He’s steps and   (19)   up. If    (20)  , they fear millions of people will develop long term health problems, costing China billions of dollars and reversing some of the country’s economic gains of the last three decades.

We find different kinds of animals in the world. Some animals, such as   (1)    and lions, live in big forest and they are called   (2)    animals. Some others like sheep and dogs are kept by men and they are called domestic animals. These animals are very different from one another, but we can   (3)   them into big groups: those that eat other animals and those that eat grass and leaves. Animals like the tiger   (4)    to the first group   (5)    eat other animals.

Animals are   (6)    great use to human beings. Men hunt wild animals for their fur and meat. Domestic animals are   (7)    more important to men. Without them, life will be difficult. People make use of animals in many   (8)   .

Cows and pigs are useful to men’s food. They give 80% of the   (9)    men eat every year. Skin of some animals can be   (10)    into expensive overcoats and shoes, which are warm and comfortable and   (11)   a long time. They are very popular in   (12)    countries. Wool, which is now one of the most important materials for textile（纺织）   (13)   , comes from some certain   (14)   . From cows, we get   (15)   . And we shouldn’t   (16)    that some domestic animals are kept for   (17)   , for example, many people   (18)    ride horses. Arabs ride on camels that travel in deserts for days without   (19)   . In some places animals are still used to plough field.   (20)    is clear that men just can’t live without these animals.

The part of the environmental movement that draws my firm's attention is the design of cities, buildings and products. When we designed America's first so-called "green" office building in New York two decades   (1)  , we felt that we were alone. But today, thousands of people come to green building conferences, and the   (2)  that buildings can be good for people and the environment will be increasingly influential in years to   (3)  .

Back in 1984, we discovered that most products for decoration weren’t designed for   (4)  use. The “energy-efficient” commercial buildings constructed after the 1970s energy crisis   (5)   indoor air quality problems caused by materials such as paint, wall covering and carpet. So far 20 years, we’ve been focusing on these materials   (6)  to the molecules(分子), looking for ways to make them   (7)   for people and the planet.

Home builders can now use materials-such as paints that release significantly   (8)   amounts of organic compounds(有机化合物) —that don’t   (9)   the quality of the air, water, or soil. Eventually,   (10)  , our basic design strategy is focused not simply on being “less bad” but on creating   (11)   healthful materials that can be either safely returned to the soil   (12)   reused by industry again and again. As a matter of   (13)  , the world’s largest carpet manufacturer has already   (14)   a carpet that is fully and safely recyclable.

Look at it this way: No one   (15)   out to create a building that destroys the planet. But our   (16)   industrial systems are inevitably(不可避免地) causing these conditions, whether we like it or not. So   (17)   of simply trying to reduce the damage, we are   (18)   a positive approach. We’re giving people high-quality, healthful products and an opportunity to make choices that have a   (19)   effect on the world. It’s not just the building industry, either. Entire cities are taking these   (20)   positive approaches to design, planning and building. Portland, Seattle and Boston have said they want to be green cities. Chicago wants to be the greenest city in the world.
