Bad teeth can be painful and even be deadly. Infections of the gums(牙齦) and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12?year?old boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed.

Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only water.

When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. The use of fluoride(氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel(釉質(zhì)), the hard surface on teeth, to help prevent holes from forming.

But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used.

Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could interfere_with the correct development of permanent teeth.

Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear—usually at around six months.

1.According to the passage，what is the function of fluoride?

A．Making the surface on teeth much cleaner.

B．Protecting gums from being infected.

C．Keeping holes on teeth from forming.

D．Slowing down bacterial growth and acid production.

2.The underlined phrase “interfere with” in Para.5 probably means “________”．

A．do harm to B．account for

C．contribute to D．stand for

3.What is the purpose of the author in writing the passage?

A．To warn us of the deadly infections of gums and teeth.

B．To introduce the advantages of fluoridated toothpaste.

C．To draw our attention to the dental care of young children.

D．To present the research results about dental care.

One might expect that the ever?growing demands of the tourist trade would bring nothing but good for the countries that receive the holiday?makers. Indeed, a rosy picture is painted for the long?term future of the holiday industry. Every month sees the building of a new hotel somewhere. And every month another rock?bound Pacific island is advertised as the ‘last paradise(天堂) on earth’．

However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy. In those countries where there was a rush to make quick money out of sea?side holidays, over?crowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.

Those countries with little experience of tourism can suffer most. In recent years, Nepal set out to attract foreign visitors to fund developments in health and education. Its forests, full of wildlife and rare flowers, were offered to tourists as one more untouched paradise. In fact, the nature all too soon felt the effects of thousands of holiday?makers traveling through the forest land. Ancient tracks became major routes for the walkers, with the consequent exploitation of precious trees and plants.

Not only can the environment of a country suffer from the sudden growth of tourism. The people as well rapidly feel its effects. Farmland makes way for hotels, roads and airports; the old way of life goes. The one?time farmer is now the servant of some multi?national organization; he is no longer his own master. Once it was his back that bore the pain; now it is his smile that is exploited. No doubt he wonders whether he wasn't happier in his village working his own land.

Thankfully, the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers. The protection of wildlife and the creation of national parks go hand in hand with tourist development and in fact obtain financial support from tourist companies. At the same time, tourists are being encouraged to respect not only the countryside they visit but also its people.

The way tourism is handled in the next ten years will decide its fate and that of the countries we all want to visit. Their needs and problems are more important than those of the tourist companies. Increased understanding in planning world?wide tourism can preserve the market for these companies. If not, in a few years' time the very things that attract tourists now may well have been destroyed.

1.What does the author indicate in the last sentence of Paragraph 1?

A．The Pacific island is a paradise.

B．The Pacific island is worth visiting.

C．The advertisement is not convincing.

D．The advertisement is not impressive.

2.The example of Nepal is used to suggest ________.

A．its natural resources are untouched

B．its forests are exploited for farmland

C．it develops well in health and education

D．it suffers from the heavy flow of tourists

3.What can we learn about the farmers from Paragraph 4?

A．They are happy to work their own lands.

B．They have to please the tourists for a living.

C．They have to struggle for their independence.

D．They are proud of working in multi?national organizations.

4.Which of the following determines the future of tourism?

A．The number of tourists.

B．The improvement of services.

C．The promotion of new products.

D．The management of tourism.

5.The author's attitude towards the development of the tourist industry is ________.

A．optimistic B．doubtful

C．objective D．negative
