2 . Britain is launching the world’s largest ever clinical trial of the Galleri test, which picks up pieces of genetic code from DNA before symptoms such as lumps (肿块) appear. The test is a game-changer for early cancer detection, which can detect more than 50 types of the disease in the very early stages. It has been developed by GRAIL, a healthcare company focusing on early cancer detection.
National Health Service (NHS) chief executive Amanda Pritchard said, “This quick and simple blood test could mark the beginning of a revolution in cancer detection and treatment here and around the world. By finding cancer before signs and symptoms appear, we have the best chance of treating it and we can give people the best chance of survival.
NHS has sent out invites across the country offering the test to 140,000 people aged 50 to 77 with no cancer symptoms. Another 6,000 with suspected signs have been offered to speed up their diagnosis (诊断). Blood samples will be taken at mobile clinics in retail parks and community locations. Laboratory analysis produces a result in a fortnight. Each test costs € 620 but NHS has negotiated a discounted price. Half the participants will have their blood screened with the Galleri test right away and samples from the rest will be stored and tested in the future. This will allow scientists to compare the stage at which any tumours (肿瘤) are detected between the two groups.
“The Galleri test can not only detect a wide range of cancer types but can also predict where the cancer is in the body with a high degree of accuracy. Earlier trial results showed it can detect 68% of 12 deadly cancers,” Health Secretary Sajid Javid said. In England 56% of cancers are diagnosed at stage one or two. NHS aims to increase that to three quarters by 2028. If found early there are a broader range of treatment options available, which can be curative and are often less aggressive.

4 . Are you at least 17 years old? Do you weigh more than 110 pounds? Do you consider yourself fairly healthy?
If you answered yes to all of these questions, you should be donating(捐赠) blood every two months. n my survey of my schoolmates, I found that only 50 percent of them have ever donated blood and that only 1 out of 13 of them donate regularly. The lack of blood donors is a serious problem that requires immediate action.
According to the American Red Cross Web pages, in the United States alone someone receives a blood transfusion(输血) once every three seconds. People who benefit from donations include cancer patients as well as babies. The need for blood never takes a vacation and neither should donors.
Let me tell you about Brooke, a three-year-old girl with cancer. Brooke has spent about half of her life in the hospital receiving treatments. Her treatment will require about 500 units of blood in total, of which only 250 units have been replaced. She still needs the other half of the total amount to continue her treatment. If she doesn’t receive this blood, she will not live to start kindergarten.
Examples like Brooke’s are becoming all too common these days, with only 1 in 20 Americans donating blood and this number keeps dropping each year. These facts are extremely worrying considering that nearly half of us here will need blood sometime in our lives.
You can now see the seriousness of the problem with the lack of blood donations. Fortunately, it is a problem that can be easily solved. Each and every one of you can be part of the solution. All you have to do is go to the nearest Red Cross and donate your blood.

In discussion of technological changes, the Internet gets most of the attention these days.But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death.Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever.But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.

7 . First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. First aid may save a life or improve certain vital signs including pulse, temperature, a clear airway, and breathing. In minor emergencies, first aid may prevent a victim’s condition from worsening and provide relief from pain. First aid must be given as quickly as possible. In the case of seriously injured, a few minutes can make the difference between complete recovery and loss of life.
First aid measures depend upon a victim’s needs and provider’s level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury , for example, can lead to permanent spinal (脊柱的) injury and paralysis (瘫痪)。
Despite the variety of injuries possible, several basic rules of first aid apply to all emergencies. The first step is to call for professional medical help. The victim, if conscious (有意识的), should be reassured that medical aid has been requested, and ask for permission to provide any first aid. Next, assess the scene, asking other people or the injured person’s family or friends about details of the injury or illness, any care that may have already been given, and preexisting conditions such as diabetes (糖尿病) or heart trouble. The victim should be checked for the medical card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim.
First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for assessing a victims condition is known by ABC, which stands for:
A — Airway: is it open and clear?
B — Breathing: is the person breathing? Look, listen, and feel for breathing.
C — Circulation: is there a pulse? Is the person bleeding extremely?
Check skin color and temperature for additional indications of circulation problems.
1. Before we give first aid to a victim, it is very important for us to ___________________.A.make sure what to do and what not to do | B.refer to all kinds of handbooks on first aid |
C.remove the ring or bracelet he/she may be wearing | D.take him/her to a hospital at once |
A.professional doctors | B.the victim’s family members |
C.the victim’s friends | D.those who are not necessarily professional doctors |
A.Checking whether there is a pulse. | B.Looking, listening and feeling for breathing. |
C.Replacing his/her medical card. | D.Examining whether the airway is open and clear. |
A.the importance of protecting the accident scene. | B.some basic knowledge about first aid. |
C.what professional medical help is. | D.who can give first aid. |
