As global warming continues to be a major concern for the future of our planet,people are starting to turn to green living practices to help save it for future generations.Green living involves every aspect of our daily life from driving to work to mowing(割草等)our lawns.
Making the switch to green living all at once might scare most people away from carrying out those earth-friendly changes.There are many ways to ease into this practice and still help save the earth’s environment.
Air pollution is a major problem for some cities.A lot of it comes from the factories, but that’s not the only way contributing to global warming.Automobiles give off a fair amount of pollutant(污染物)into the air.When you have a lot of cars driving around on the city streets, you’re multiplying the amounts of pollutant being emitted(发出)by each car that’s destroying our ozone(臭氧).If you want to save the environment,you can start by either car pooling,walking more instead of driving or even purchasing hybrid(混合的)models that don’t do as much damage.
Then let’s take a look at your home.What kinds of bulbs are you using? The standard bulbs we use only contribute to higher electricity bills and more carbon dioxide.If you switch at least some of your standard bulbs with the compact fluorescent(荧光)bulbs,you can save the environment while saving on your electric bill.
Recycling is also an excellent way to save our environment.Try to buy as many products as you can that can be recycled.The less trash that has to be burned or buried into our soil,the better off our planet will be.
These small changes may seem that they couldn’t help much for the environment,but they can help tremendously.Every little bit we do is a much-needed step toward reserving(保留)natural resources for our future generations.

A.few people are concerned about the environmental problems
B.more and more people are interested in green living practices
C.what green 1iving practices in modern society are
D.green living practices don’t help in our daily life

A.they are asked to do something to save the environment
B.they can’t drive to work any more
C.they are required to turn to green living completely at once
D.they are made to pay for the pollution they cause
70.In order to give off less harmful gas into the air, we can .
A.close all the factories that may cause pollution
B.limit the car production
C.forbid too many cars to run in the streets
D.choose those cars which may cause the least pollution
71.The author recommends recyclable products because .
A.they are made in green factories
B.they are cheaper than other goods
C.they will help to reduce trash on the earth
D.they can be used for a very long time
Easter(复活节 ) 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 (栖息地) 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(捕食者).As the number of days with snow decreases all across the country, however, more and more bunnies arc 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 firs' 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 (迁徙) 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.
【小题1】The writer mentions Easter at the beginning of the passage in order to_______.
