Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient - no matter where he or she may be.
Online doctors offering advice based on norman symptoms（症状）are the most obvious example. Increasingly, however, remote diagnosis（远程诊断）will be based on real physiological data（生理数据）from the actual patient. A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone ,it is perfectly practical to send a patient’s important signs over the telephone. With this kind of equipement, the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to rural （countryside） care. And at least one team wants to use telemedicine as a tool for disaster need - especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts’ opinions.
But there is one problem. Bandwidth（宽带） is the limiting factor for sending complex （复杂）medical pictures around the world,—CU photos being one of the biggest bandwidth users. Communication satellites say be able to deal with the short - term needs during disasters such as earthquakes or wars. But medicine is looking towards both the second - generation Internet and third generation mobile phones for the future of remote medical service.
Doctors have met to discuss computer - based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts’opinions and diagnosis are common.
The writer chiefly talks about ________ .
| A．the use of telemedicine |
| B．the on -lined doctors |
| C．medical care and treatment |
| D．communication improvement |
Which of the following statements is true according to the text?
| A．Patients don’t need doctors in hospitals any more. |
| B．It is impossible to send a patient’s signs over the telephone. |
| C．Many teams use telemedicine dealing with disasters now. |
| D．Broadband communications will become cheaper in the future. |
The“problem”in the fourth paragraph refers to the fact that ________ .
| A．bandwidth isn’t big enough to send complex medical pictures |
| B．the second - generation of Internet has not become popular yet |
| C．communication satellites can only deal with short - term needs |
| D．there is not enough equipment for spreading the medical care |
Bad teeth may be painful and it’s getting worse without treatment. They can even ruin your life. Illness of the teeth can find its way into the blood system. This can increase the chances of a heart disease or other illnesses.
Experts say good care for teeth should start at birth. Mothers’ milk is the best food for the healthy development of teeth.
But dentists say a baby’s mouth and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, give him only water.
When baby’s 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. Young children often eat toothpaste (牙膏) when they brush, so they should be carefully watched when they brush their teeth.
Parents often ask what effect thumb sucking (咬手指) might have on their baby’s teeth. Experts generally agree that this is fine early in life. Most children stop sucking their thumbs by the age of four. If it continues, parents should talk to their children’s dentist or doctor.
Dentists say children should have their first dental visit by the time they are one year old. They say babies should be examined when their first teeth appear usually at around six months.Why should people pay attention to teeth problems?
| A．They can cause other illnesses. |
| B．They will bring bad luck. |
| C．They will bring the family much trouble. |
| D．They usually last a long time. |
According to the writer, baby’s teeth should be protected from the day ______.
| A．he begins to speak | B．he has his first tooth |
| C．he was born | D．he is fed with bottle milk |
The underlined word “it” in Paragraph 5 refers to “_____”.
| A．toothache | B．parents’ trouble | C．thumb sucking | D．experts’ advice |

Eyesight problems are common among all ages and if they are left untreated, they can cause serious headaches or other problems. The good news is that most eyesight problems can easily be sorted out by wearing glasses.
Regular eye tests are important for everyone. Children and teenagers, under the age of 16 and up to the age of 19 for those full-time education, have the right to have eye tests for free in Britain. As the eye test is free, there’s no excuse for not having a regular eye test. Doctors suggest that it’s better to have an eye test about once a year.
Wearing glasses isn’t always regarded as all that cool and teens who suddenly need to wear glasses may find it difficult to accept.

Twothirds of the world's major rivers have now been disrupted with more than 50,000 dams in an attempt to store water and provide power.In the US，there are more than 85,000 dams，disrupting large and small rivers，and in most cases transforming natural flow.The most famous of these，the Hoover Dam，constructed in the 1930s，is mainly responsible for the fact that the Colorado River no longer reaches the ocean.
Dams，besides all their attractive benefits，also have negative impacts.Creating a reservoir means a large area must be flooded.Communities may lose their land，houses and culturally important sites.
Environmentally，the new reservoir can be a paradise for wildlife，especially birds；however，it can cause greenhouse gas emissions and poison the water.Also，the dramatic rise and fall of water levels during dam releases is too extreme for plants and animals to cope with，resulting in dead zones around the shores of reservoirs.Fish that lay their eggs in the shallows，for example，may find a few hours later that those sites are high and dry.
Downstream(在下游方向)of a dam，the flow may be reduced so that farmers cannot irrigate their fields.Many rivers run through national borders，which may cause conflict over precious water.Disputes have been continuing between India and Pakistan，and Turkey，Syria and Iraq，for example.
Dams don't just block the flow of water.They also prevent fish migrations，and dams are a barrier to sediment(沉淀物)flows.Instead of rushing downriver，sediments get backed up against the dam wall，which causes the reservoir level to increase over time.However，sediments which are rich in nutrients have become a problem.The fertility of the entire system can be influenced，with soils lost during seasonal rains not being replaced.
Perhaps the biggest problem can be seen in deltas，which are sinking into the oceans.Groundwater is being extracted to feed the city，causing the city to sink，and sediments washed away by the ocean are no longer being replaced.The result is that sea level rises in cities from Shanghai to Alexandria.The Hoover Dam is mentioned in the passage in order to show________.
| A．dams play an important role in our life |
| B．dams have impacted the flow of the rivers |
| C．dams make people lose their land and houses |
| D．dams have many benefits as well as side effects |

a．People will see fewer birds on the sides of the rivers.
b．Farmers will have less water to irrigate their fields.
c．Visitors can't visit some cultural relics any more.
d．More conflicts and wars over water will break out.
