Every time you go to the supermarket you come away with your purchases packed in plastic bags. But wouldn’t it be kinder to the environment if you asked for paper bags instead?
The answer is not as easy as it might seem. Environmentalists say there are drawbacks to using both plastic bags and paper bags.
80 percent of groceries in the US are packed in plastic bags and the numbers are becoming huge. Consumers use between 500 billion and 1 trillion plastic bags per year worldwide.
Some experts believe that all these bags harm the environment. Plastic takes hundreds of years to break down and, as it does so, poisonous materials are released into the water and soil.
Further damage is caused if plastic bags enter the sea. For example, endangered sea turtles cannot tell the bags from jellyfish, their main source of food, and often choke on them.
However, this kind of bag does have its advantages.
Paper bags use more energy and create more waste than plastic bags. Plastic bags require 40 percent less energy to produce and cause 70 percent less air pollution. They also release as much as 94 percent less waste into the water than paper ones do.
But paper bags do break down more quickly than plastic bags. They don’t endanger wildlife, either.
So what should we do? One possible solution would be to use biodegradable plastic bags. “Biodegradable” means that the bags break down naturally just like a piece of banana peel when it is left outside.
But until biodegradable technology improves, it might be easier to pack things you buy in reusable cloth bags.
1.Compared to paper bags, plastic bags ______.
A. produce 6 percent more waste
B. can be made biodegradable more easily
C. can be used as a source of food
D. save 40 percent of the energy
2.By saying “The answer is not as easy as it might seem,” (in paragraph 2) the writer means _____.
A. biodegradable plastic bags can compete with paper
B. paper bags seem to be kind to environment
C. it’s difficult to say whether plastic or paper bags are better for the environment
3.What does the author suggest people use at the present time?
A. Paper bags B. Plastic bags
C. Biodegradable plastic bags. D. Cloth bags.

I was so afraid of 24 , especially here ,and I think most of us were not 25 to crossing so high a bridge 26 ,our team leader told us that we must cross this bridge in order to see the splendid falls that lie out on the other 27 .
“As you cross this bridge,think about 28 difficult,but it is possible”.
Many times in our lives we face 29 that we don’t expect---broken relationships,betrayal(背叛)of a friend, etc.,and all we can do is 30 . But I noticed that life must go on, and all the burdens must be 31 through forgiveness---forgiveness of yourself and others.
