When you go shopping，you are given at least one plastic bag to carry what you’ve bought.They are so common that we don’t often give them a second thought.But the beginning of the end may have come for the plastic bag.

A small town in Tasmania，an island off the south coast of mainland Australia，is making itself an environmental role model (模范) by becoming the country’s first plasticbagfree town.

Since April 28，Coles Bay’s population of 175 and its tourist shoppers have been using reusable paper or cloth bags to carry their shopping.

Coles Bay sits on the edge of the beautiful Freycinet national park.Around 180,000 tourists pass through the town and the park every year.

Ben Kearney，a local businessman who supports the bag ban，said it would cut the amount of waste and prevent damage to native wildlife who try to eat the plastic.

“Most of the business here comes from the tourism and that’s all based on the environment，so people were pretty supportive.”he said.

Every year Australians use more than 6 million plastic bags.More than half of these come from supermarkets.Since_it_takes_years_for_the_bags_to_biodegrade_(生物分解)，tens_of_millions_end_up_polluting_the_environment.They kill about 100,000 seabirds and animals，which mistake the bags for food，every year.

Only in the past few months have major Australian supermarkets begun cutting down on their use of plastic bags.Environmental groups are pushing for a plastic bag fee (费) like that in Ireland.There，since plastic bags cost 10 pence (about 1 yuan) each，their use has been cut by 90 percent.

Pollution caused by plastic bags is a big headache for countries all over the world.As early as 1999，Beijing said that only plastic bags of certain thickness could be used.This was to encourage them to be used again and again.In China’s capital alone，an average of 6 million plastic bags are used every single day.

Losing a baby tooth can be fun for a kid. You can put it under your pillow and look forward to finding some money there in the morning. And then you can watch your new permanent(永恒的) tooth grow in its place.

But if a permanent tooth falls out, that’s a problem. There isn’t another one under the gum(齿龈)that can replace it. Unfortunately, this happens to some older people. And if permanent teeth fall out-or need to be pulled-an older person might need dentures.

Dentures, known as false teeth, are a set of replacement teeth for any teeth that are missing. There are partial dentures, which take the place of only a few teeth and prevent the others from changing position. If all the teeth are gone, the person would need complete dentures, which replace every tooth in the mouth.

Dentures can cause pains at first and take some time to get adjusted to. They also need special care. They should be brushed daily with a special denture brush and cleanser and soaked in denture solution when not in the mouth.

Dentures are important for older folks because, without teeth, it’s hard to smile, talk, and eat properly. But it can be a little weird if you see someone take out his or her dentures. It can also be strange to see someone, like a grandparent, without dentures in because he or she won’t have any teeth. Try not to make fun of the person because this could cause hurt feelings.

People usually lose their permanent teeth due to periodontal disease, or gum disease, which is caused by bacteria that attacks the gums. Diseased gums aren’t strong and healthy, so teeth can get loose and fall out. Older people often have many cavities(洞)that have been filled over the years, and these fillings can weaken over time, leading to more tooth decay(腐烂).

If one of your baby teeth falls out, he or she .

A．should have a false tooth fixed in its place

B．have to put it under your pillow at once

C．will gain a permanent tooth in future

D．can exchange it for some money

A person wearing dentures .

A．should brush them with a special denture brush every few days

B．will take a very long time to adjust himself or herself to them

C．will experience unpleasant feelings at the beginning of fixing them

D．should use denture solution to soak them in his or her mouth

Which of the following is NOT true according to the passage?

A．Partial dentures can prevent the remaining teeth from changing position.

B．Old people will find it hard to smile, talk, and eat properly without teeth.

C．A person’s teeth will possibly get loose if diseases strike his gums.

D．It is hard for a person to wear dentures if all his teeth have fallen out.

What does the underlined word “weird” mean in the fifth paragraph?

A．inconvenient B．strange C．uncomfortable D．impolite
