1. The world’s leading transplant surgeon, Dr Christopher Bernard,
has carried out one of the most difficult brain tissue transplants yet attempted. The South African surgeon has succeeded in transplanting tissues into the human brain in what is thought to be the first operation of its kind. The surgery was performed a week ago on a patient suffering from Parkinson’s disease. A portion of the patient’s adrenal gland was implanted into a part of the patient’s brain, an operation which has previously been performed only on rats and monkeys.
2. Approximately a third of all people develop cancer at one point in their lives. Chemotherapy has its limitations, but it is one of the major treatment options. Some American scientists have discovered they can increase the effectiveness of chemotherapy by inhibiting a natural defense mechanism employed by cancer cells. 3. Glaucoma is responsible for blindness in an estimated 67 million people around the world. Until now, treatments have focused exclusively on the eyes. But that may change in the next few year, following the discovery that glaucoma involves the death of brain cells.
4. New research shows that the simple act of writing down thoughts about a stressful event can help people with chronic illnesses improve their health. This is the first study to show that writing can result in clinically meaningful outcomes for chronically-ill patients.
The study adds to the growing amount of scientific literature suggesting that meeting patient’s psychological needs produces physical health benefits.
5. Traditional Chinese medicine says that good health is associated with the balance of Qi. Qi can be hindered or helped by yang and yin. According to traditional theory, the goal of acupuncture is to promote the flow of qi by keeping yin and yang in balance ---- and this is done by inserting needles at various points along primary channels and meridians that crisscross the body. One of the key benefits of acupuncture is that it has few, if any, side-effects; and that when used with standard drug treatment --- in anesthesia, for example --- it allows physicians to cut back on medication, delivering the same level of benefit with fewer negative effects/ B

Part II（答案见听力原文中的红色部分）
In North Beach in San Francisco, where some pretty super food gets served every night. “Absolutely very super food!” “and I really like the taste of it”
But we’re not just talking about taste. Research now shows that some foods, including tomatoes, onions, garlic, and olive oil ---- are among the super foods. Super foods are packed with powerful chemicals that may offer your body great protection against chronic disease “Including cancer, obesity, heart disease. Vibrantly colored red, yellow, orange and green all giving you different types of phytochemicals.”
Natalie Ledsma is a registered dietician at U. C. S. F. she says compounds found in super foods --- called phytochemicals ---- can reduce the risk of cancer, boost the immune system, and protect the heart. She showed us what everyone should try to eat each week for optimal health. One her shoppinglist? Herbs!
“Dark green ones (herbs), like rosemary and thyme, and any intensely colored spice, like turmeric or red pepper.”
“Both of those have anti-inflammatory properties.”
Turmeric many reduce the risk of leukemia, skin, and liver cancers. Hot peppers may reduce the risk of colon, stomach, and rectal cancers. Also on the list: green veggies. But not just nay green veggy.
“Brussels sprouts are part of the cruciferous vegetable family that has significant anti-cancer properties, and that family also has a very favorable effect on hormone metabolism.”
Other cruciferous veggies include cabbage, broccoli, and cauliflower. And don’t forget the tomato.
“it is probably the best source of lycopene, which is one of the phytochemicals that has shown significant anticancer properties, especially with prostate and potentially lung and breast cancer as well.”
As for fruit, citrus contains Vitamins C, limonoids, and phenols, which inactivate cancer cells and strengthen the immune system. Cantaloupes, mangos and carrots contain cancer-fighting carotenoids. And berries are bursting with flavonoids and ellagic acid ---- antioxidants that protect against cancer, ulcers, and viruses. Natalie recommends organic.
“Organic fruits and vegetables have shown not only to have lower pesticide toxicities and lower pesticide levels, but also now have been shown to have higher phytochemical content.”
Don’t forget the fatty fish or flaxseed ---- both are excellent source of Omega 3 fatty acids that inhibit the growth of cancer cells and boost the immune system, olive oil, which may reduce breast, prostate, or colon cancer, and soy.
“soy has protective effects for heart disease as well as osteoporosis, potentially.”
And finally onions, garlic, and shallots. They may protect the heart fight cancer, and help with asthma.

Salt is crucial to our health, but too much of it can put human at risk from high blood pressure, heart disease and stroke. Many reports, researchers at Harvard Medical School say the significant reduction in salt intake can cut the chances of heart disease and strokes by a quarter. Here is our health correspondent, Adam Brimelow.
It’s long been known that cutting salt can reduce blood pressure. But there has been much less evidence of what it means for cardiovascular disease, including heart attacks and strokes. The Harvard team followed
up people with borderline high blood pressure, who had taken in part in two salt reduction studies, typically cutting intake from 10 to 7 grams a day. The risk of developing cardiovascular disease over the next decade or so was cut by a quarter compared with those who did not reduce their salt intake. And their chances of dying from cardiovascular disease fell by 5/1. In developed countries such as the United States and the UK, the average adult daily salt intake is about 10 grams. Much of this is already in the food that people buy, including processed foods and bread. Many experts say no one should have more than 3 grams. They say the best way to cut salt, is to get away from fast food, check labels and have plenty of fresh fruit and vegetable. Adam Brimelow reporting.

Tapescript 听力原文：
Maryland may be a small state, but it's a major player in developing emergency medical services. There are 49 hospitals that have 24-hour emergency departments. Nine of those hospitals are specially designated shock trauma centers, and there's a sophisticated communication center that links the state's ambulances, helicopters, and the hospitals.
\"A serious accident happens. Pre-hospital staff --paramedics, emergency medical technicians--through a sophisticated communication system know where and when the accident happened, and they are summoned immediately to provide the initial, quick, life-saving care.\"
That's Dr Philip Militello. He's head of trauma surgery for the state system. If you have a serious injury anywhere in Maryland, this system will get you the right treatment with the least delay. What kind of help do you need? Where's the closest hospital? Should you go by ambulance or by helicopter? The answers to these questions come through sophisticated
communications. The system springs into action with a telephone call to 911, your local emergency number anywhere in the state. \"Fire and rescue.”'
If you're injured, your call is forwarded to the fire department's emergency rescue service. Based on the information you give them, they send a radio call for the nearest available help.
\"He has been shot. Hold on while I dispatch an ambulance.\"
A man has shot himself. The nearest available shock trauma ambulance is twenty minutes away. But a paramedic supervisor with some emergency medical equipment in his car responds to the radio call and arrives on the scene within nine minutes. The supervisor, Lieutenant Mike Fahey, is a nationally certified paramedic. He quietly talks to the patient while he bandages the bullet hole. Finding the patient's blood pressure alarmingly low, he immediately starts intravenous blood plasma. His movements are deliberate and his voice is calm.
\"Come in. Take control of the situation. Remain calm. Chaos is contagious, and so is the calm that you have. When the patient looks up at you and you're calm, then you're reassuring. Then they calm down.\"
The paramedic ambulance with advanced life support equipment arrives twelve minutes later, and Fahey's patient is loaded on a stretcher, ready to go. But the patient is in shock. If he stays in shock, he has a poor
chance of survival. Inside the ambulance, they start another line of plasma and apply medical anti-shock trousers. Those are rubberized trousers to squeeze the blood from the legs back to the brain and other vital organs. Through radio communication everyone has agreed to send him by ambulance to the regional shock trauma center. It's only six minutes by land; it's available; and the regional center is equipped for his particular injury.
\"They're putting on the trousers now. As soon as they get that, they'll be able to start going down the highway. '
\"If we can get the patient to the trauma center within twenty minutes, we go by land. If it's going to be longer than twenty minutes, we try to go by air.\"
Captain Linda Sterling. She's Mike Fahey's boss at the local emergency medical service. When one of her paramedics needs a medevac helicopter, the request goes quickly to the SYSCOM, the statewide System Communication Center. Three large screens dominate the darkened room at SYSCOM. The right screen shows which hospital can take what kind of injury. The center screen shows the location of all medevac helicopters. And the one on the left shows the helicopter landing pad at
the main shock trauma center. SYSCOM operations chief Andy Polavski tells us what's happening.
\"Part of the operation here is the SYSCOM operation: system communications. They serve as the coordinators of the medevac activity in the state. This is the dispatch point for the State Police helicopters and the U.S. Park Police helicopters.\"
SYSCOM can also connect by radio any paramedic in the state with any hospital or any emergency specialist. In shock trauma injuries, minutes can mean life or death. Maryland's communication system saves precious time by connecting citizens, ambulances, helicopters, and hospitals. Dr R. Adams Cowley, founder of the system, said, \"If I can get you and stop your bleeding and restore your blood pressure within an hour of your accident, then I can probably save your life.

2. proper timetable

4. private healthcare c: more widely available 听力原文：
It seems that politicians around the world are thinking about the health of their countries. While in China, Chen Zhu has announced his plans for a universal health service and reform across health services, Gordon Brown, the UK Prime Minister, ahs also announced he is planning to make some changes in our heath service.
The crux of Mr. Brown’s proposals are related to giving the NHS（National Health Service）a greater focus on prevention, rather than just curing patients.
He is planning to introduce increased screening for common diseases such as heart disease, strokes, and cancer, for example breast cancer. In Britain there are 200,000 deaths a year from heart attacks and strokes, many of which might have been avoided if the condition had been known about.
Initially, the diagnostic tests will be available fro those who are most vulnerable, or most likely to have the disease, but later on the Prime Minister claims that they will be more widely available. One example is a
plan to offer all men over 65 an ultrasound test to check for problems with the main artery, a condition which kills 3,000 men a year.
The opposition have criticized Mr Brown’s proposals, saying that they are just a gimmick, and claiming that there is no proper timetable for the changes. They also say that Mr. Brown is reducing the money available for the treatment of certain conditions while putting more money towards testing for them.
The NHS was founded in 1948, and is paid for by taxation. The idea is that the rich pa more towards the health service than the poor. However in recent years there has been a great increase in the use of private healthcare.
Many people who can afford it choose to pay for medical care, often because it can be quicker, although the doctors and hospitals are often the same!! NHS waiting lists for operations can be very long, so people can jump the queue by paying for their operation. 生词： Brain tissue
