Future medicine should help people get a healthier life, they must have less bad or negative effect, and they also have to involve in our life and diet deeply.I’ ve been to Japan , there l saw various kinds of vitamin supplements are sold in their market and parapharmacie . Japanese take these medicines as daily nutrition every day to keep healthy.So I believe this must be the direction of the future medicine. Future medicine should be a part of human being’s life, play an important role and insure our health generation after generation3. diabetesDiabetes is the name for a medical condition in which too much glucose(葡萄糖), or sugar, builds up in the blood. Diabetes develops when the body does not make enough of the hormone insulin（胰岛素）or makes no insulin at all. It also can develop when the body is not able to use the insulin that is made.The body changes food into a sugar called glucose. Glucose enters the blood and is taken to cells in all parts of the body. Insulin helps the muscles, organs and tissues（组织）take in the glucose and change it into energy.The pancreas(胰腺) is the organ that produces insulin. When too much glucose in the blood, the pancreas produces the necessary insulin and sends it into the blood. The insulin reduces the level of blood sugar by letting it enter cells.Diabetes is present when too much glucose remains in the blood and does not enter cells. If the amount of glucose in the blood remains too high, it begins to damage the body.Over time, diabetes can cause blindness, kidney（肾脏）disease, and nerve damage. High glucose levels in the blood also can lead to strokes and heart disease. Blood flow also is affected, especially in thelegs. Often, victims of diabetes must have a foot or even a leg removed because of problems linked to the disease. Diabetes patients are more likely than other people to die of heart disease or kidney failure.There are two main kinds of diabetes.Type one diabetes generally affects children and young people. It results from a lack of insulin production. The exact cause is not known. But some experts believe the body's defenses against disease for some reason destroy the cells that produce insulin.Signs of the disease may develop suddenly. People suffering from type one Diabetes may develop a strong desire for food or something to drink. Other signs are increased production of liquid wastes, loss of body weight, changes in eyesight and feeling extremely tired.People with type one diabetes almost always need daily injections of insulin. Diabetes patients must always know their blood sugar levels. When glucose levels are too high, they must use insulin to reduce them. And they may use medicines that help reduce their glucose levels.The World Health Organization estimates that about ninety percent of people with diabetes worldwide have type two. This kind of diabetes was seen only in adults until recently. It is now being increasingly seen in children who are very fat.Most people with type two diabetes are overweight and need physicalexercise. Their bodies cannot produce enough insulin to reduce glucose levels in their blood. Or their bodies do not react correctly to the insulin being produced.Signs of type two diabetes are similar to those of type one. But experts say many people with type two diabetes have no signs. As a result, the disease may not be recognized until after the patient has already begun to develop medical problems.Experts say genes seem to be important in the development of diabetes. They say that about ninety percent of those with type two diabetes have family members who also had the disease.Some women develop unexpected diabetes during pregnancy. This is called gestational diabetes, and usually disappears after the baby is born. Do physical exercises; keep a balanced diet ; avoid the food which contains high sugar and high fatGreen tea , pea, tripe these food can help us getting away from diabetes.4. studying abroadWhy Study Abroad?Besides the excitement of travel, one reason to study abroad is that you will experience new customs, holidays, foods, art, music, and politics firsthand.Another reason for studying abroad is that you'll gain self-confidence. One can learn how to better stand up for himself and his beliefs and to express himself in another language. What could make you more confident than that?Living away from home can also help you adjust in the transition to college and adulthood.And speaking of college, improving your language skills might help you get into choice colleges and even land future jobs. Colleges and employers know that studying abroad provides leadership skills in a world that is increasingly globally interconnected.But there’s one point we should know that studying abroad is not a wise decision to everyone.Study abroad programs only look for students who are independent, self-assured, enjoy new experiences and different types of people, and can handle challenges. When you study in a foreign country, you'll befaced with new circumstances, environments, and predicaments(窘境). So ask yourself whether you can handle those complex and new situations in your new college, you should also prepare for your further study. In addition to preparing physically, don't neglect your emotional health. Consider journal writing to help process your experience. And prepare for culture shock when you return — you've grown and so have friends and family. You'll also miss your host family and friends. Finally, if you make your decision then go ahead and never give up in the half way.5. environmental toxinsNowadays , our environment is filled with various kinds of toxins . In my point of view , the major sources of the environmental toxins are from industrial discharge and agricultural pesticides and automobiles.Most industrial factories let chemical waste out and discharge them into water which cause damages to the marine environment and threatening human life through contaminated seafood.Agricultural pesticides also bring about many environmental toxins. They are spread by farmers to prevent insects but, at the same time, they are threatening human’s life too. Because most of chemical elements they contain are harmful to human’s health, especially when they are overspread.With the growth of the number of automobiles, despite of the convenience they bring to us, they are also responsible for a great part of toxins spread in the air.Establishing and improving environmental protection.How to improve this problem?Government should publish strict law to control the discharge of chemical toxins in air or river, and unqualified factories must be closed or moved out.Control the dosage of pesticides, and develop the technique of transgenic plant, this kind of plants have less harmful chemical toxins.The most effective way is to government’s control the number of private cars.Speeding up technological progress must also be considered. Gasoline industry should provide high-quality gasoline with less harmful components. And more hydrogen-cars should take the place of the automobiles.6. medical mythsDo you know medical myths are around everyone in our daily life.Here are some medical beliefs:Drink at least eight glasses of water a dayWe use only 10% of our brainsHair and fingernails continue to grow after deathReading in dim light ruins your eyesightDo you believe these? Well, they are remembered as common knowledge and kept deeply in my mind.This kind of beliefs usually has no evidential proof. And illusion may also be to blame for the belief.Why these medical seems to be difficult to be corrected?The difficulty is it is often hard to disprove a theory. And what’s more, you know, absence of evidence does not necessarily mean absence of effect.7. stressWhat Is Stress?Stress is a feeling that's created when we react to particular events. It's the body's way of rising to a challenge and preparing to meet a tough situation with focus, strength, stamina(毅力), and heightened alertness. Stress is a natural reaction of human beings to the situation. Because of lacking skills to control the bad situations and the tough competition, fast pace of the modern society, most of us were troubled with stress. Too much stress does harm to our mental and physical health.Cause : sub-health(亚健康) , be crapulentAnxiety, depression, nervousHow to handle stress problems?As far as I’m concerned, one can choose to take physical exercises to ease his tension. He should arrange his working time and time for fun properly, take frequent break while working or studying to relax himself. Wha t’s more, he may also share his stress to others, communication must be an effective way to lose your nervous and confusion.8. dental care(牙齿护理)People have been troubled by tooth and gum problems for thousands of years. The earliest record of dental treatment comes from ancient Egypt. Dental care is important, we should put more attention on our daily dental care.Good teeth make you more confident, a bright smile, a good appetite How to care your teeth?Basic Dental Care- Brushing, Flossing, Check-Up'sIn order to make your teeth more health : brush your teeth twice every day, go to the dentist regularly, avoid soft drinks and acidic food, take vitamin c more often, use dental floss and mouthwash .If you follow all of those simple steps, maintenance of your dental health is assured. And seeing as your mouth is more important than just a set of pearly whites, it should be considered time and effort well spent.9. mental healthThe World Health Organization says more than four hundred fifty million people suffer from poor mental health. The most common disorders are depression and schizophrenia(精神分裂). Mental health experts also include other disorders like drug and alcohol abuse that affect millions of people.So mental health are calling people’s attention for it has become a neglected issue.How to keep mental health nowadays?In my opinion, first of all is to keep moods and emotion steady. You know there are too many reasons to make us lose our tempers in reality. Especially people cannot control themselves for anger, worry, sadness and so on.On the other hand, for keeping our mental health, I think we had better accept healthy messages any time, and refuse those unhealthy ones. Such as in reading books, watching TV. For what? As all the messages will enter our minds and become a part of our life.10. Pregnancy careHeavy, inconvenient to move, pregnancy reactionSome advice:1. Early pregnant pregnancy reaction 早期孕妇的妊娠反应，为了减缓反应，采取措施：Lemon juice, hawthorn, juice, potatoes, biscuits and other food can be helpful.2.疲倦嗜睡tired and always sleepy.

And improve your own immune system.5. Taking in nutrition greatly is not encouraged.6. 当心辐射watching out radiation.7. 走路小心be careful.8. Husband is important. He should taking good care of his wife like doing housework.11.Health care for the oldWith China’s aging populat ion tendency, it poses a serious challenge to the support and the health care for the elderly.Young people should often go home, there’s no need of too much money but chatting with them and telling them they are not alone.But as young generation are taking a heavy burden of supporting the old nowadays. The old should also take care of themselves.The old have to be sent to the nursing home (敬老院).1. The old can join in some activities and communities. Keep their hobbies also.2. Often doing exercise to keep health13. plastic surgeryPlastic surgery include cosmetic surgery and reconstructive surgery. Reconstructive plastic surgery is used to correct abnormal structures of the body. These abnormalities are usually caused developmentally, or through tumors or diseases. Reconstructive plastic surgery is typically performed to improve functions, however it is sometimes performed where a normal appearance is desired.On the contrary, cosmetic surgery is performed to improve your appearance and self-esteem. Cosmetic surgery involves reshaping parts of the body that are otherwise functioning properly.Cosmetic Surgery includes:∙Botox∙Blepharoplasty (Eyelid Surgery)∙Breast Augmentation∙Breast Lift∙Face Lift∙Hair Replacement∙Liposuction∙Laser Skin Resurfacing∙Neck Lift1)Teacher let us see a video that shows one woman had agummy smile ,and she just had botox injection , and it made her smile nature and beautiful. Because botox can paralyse the elevater muscle.Botox is a temporary way to help rejuvenate the face through non-surgical means. Botox is injected into desired areas and the effects generally last a few months before re-application is necessary. The entire BOTOX? Cosmetic injection procedure takes approximately 10 minutes. After the procedure. There’s no recovery time needed. You’re ready to get on with your day! Within days, you may notice an improvement in the moderate to severe frown lines between your brows that can last up to 4 months. Results may vary.2)we also talked about liposuction and nose job and so on.3)Side effectsNausea and Vomiting1.Nausea and vomiting are the most common side effects after acosmetic surgery procedure. This is largely due to the use of anesthesia to put the patient under during the operation. However, many cosmetic surgeons are opting for more localized anesthesia that does not require an anesthesiologist to be present.Performing the surgery in this way leaves the patient with less problems with nausea and vomiting upon exiting surgery.Blood Clots2.Blood clots are common problem with any surgical procedureincluding cosmetic surgery. Blood clots occur when you leave part of your body immobile for a long period of time, such as when recouping from your surgery. Once the area has been immobile for too long, blood begins to pool. The pooling then turns into a clot.As long as the clot breaks up slowly there is no problem. However, if the full clot dislodges itself, it can travel through the entire body until it reaches the heart or brain causing a heart attack or stroke. Suture Complications3.Another common complication has to do with the sutures used toseal the skin tissue back up until it has had time to heal. If these sutures are too loose they can come undone causing mild to massive internal bleeding or hernias. If not caught quickly this could lead to a great amount of blood loss. It also requires additional surgery to repair the affected area.Infection4.Infection is another common side effect of surgery. During theprocedure, and during the healing time after the surgery, the patient is vulnerable to infection of the open areas of the tissue. In mild cases an infection may just slow down the amount of time your surgical wounds take to heal. However, in severe cases an infection can spread and even kill you.Anesthesia5.Anytime you need anesthesia for an operation there areserious health risks. The first of these is blocked airways. Many times anesthesia may cause irritation to the airways. This causes your vocal chords to spasm which in turn blocks air from entering your lungs. If this happens, the anesthesiologist will have to either insert a tube or cut a opening in your windpipe to allow you to breathe. Anesthesia may also trigger an allergic reaction to the chemicals used during the process. In rare cases, anesthesia may even cause death.。

英语口语Presentation素材Optimus Prime, leader of the benevolent Autobots, narrates the collapse of the Transformers' home world, Cybertron. It was destroyed by war between the Autobots and the malevolent Decepticons, lead by Megatron in his quest to get hold of the All Spark. The Autobots want to find the All Spark so they can use it to rebuild Cybertron and end the war, while the Decepticons want to use it to defeat the Autobots and take over the universe. Megatron had managed to locate the All Spark on Earth, but crash-landed in the Arctic Circle and froze in the ice. After stumbling upon his frozen body in 1897, explorer Captain Archibald Witwicky accidentally activated Megatron's navigational system and his eye glasses were imprinted with the coordinates of the All Spark's location, an incident that left him blind and mentally unstable. Sector 7, a secret government organization created by President Herbert Hoover, discovered the All Spark in the Colorado River and built the Hoover Dam around it to mask its energy emissions. The still-frozen Megatron was moved into this facility and was used to advance human technology through reverse engineering.In the present day, the Decepticon known as Blackout arrives in a U.S. military base in Qatar to find the location of Megatron and the AllSpark. He tries to hack into the files of the computer base, but is stopped by Captain William Lennox and his team. Back in the United States, Captain Witwicky's descendant Sam Witwicky buys his first car which turns out to be the Autobot scout Bumblebee and helps him woo his crush Mikaela Banes. Later, Sam catches a glimpse of Bumblebee's true form when he signals the other Autobots.On Air Force One, another Decepticon named Frenzy infiltrates the plane and tries to hack into the network again, only this time is more successful until he is stopped by the US Security Defense before he can retrieve all of the file information. Frenzy is then picked up by his partner Barricade and they go after Sam after learning he has the glasses needed to find the AllSpark. Sam is rescued by Bumblebee and Mikaela also learns of the Transformers' existence. Bumblebee fights Barricade and manages to subdue him while Sam and Mikaela decapitate Frenzy, but he still survives.Meanwhile, Scorponok, who was sent by Blackout, goes after Captain Lennox and his team, murdering one of them and injuring another. During the battle, Scorponok is forced to retreat when he gets injured by sabot rounds dropped him by the Air Force. Sam and Mikaela soon meet Optimus Prime and his other Autobot partners Jazz, Ironhide, and Ratchet. They explain their origins to the two humans and insist on the urgency to get to the Allspark first before the Decepticons, knowing that the Decepticons plan to use it to turn all of Earth's technologies into a new army of Transformers and render humanity extinct. The Autobots bring the two humans back to Sam's house to find the glasses, and they nearly reveal their existence to Sam's parents.However, Sector 7 agent Seymour Simmons and his team find Sam and take his family away to a classified location after learning Sam came into contact with the Autobots. However, Sam and Mikaela are rescued by Optimus and the Autobots, but Bumblebee ends up getting captured. The Autobots get the glasses and use them to find the AllSpark's location so they can destroy it so the Decepticons cannot get to it. Sam and Mikaelaalong with two hackers named Maggie and Glenn arrive at the Hoover Dam, where Maggie and Glenn got arrested by the FBI for trying to decipher the information Frenzy stole.Frenzy finds the AllSpark and gets his body back, then contacts the other Decepticons, Starscream, Bonecrusher, Soundwave, Brawl, Barricade, and Blackout. Starscream attacks the dam and Frenzy frees Megatron from his frozen prison, where he joins his cohorts into chasing down Sam and the Autobots, where Bumblebee has shrunk the cube to a reasonable size. They then get to Mission City, where a large battle ensues. Working together, the Autobots and human soldiers manage to bring down Bonecrusher, Blackout, Brawl. However the war caused Bumblebee to get crippled, and Jazz is killed by Megatron.Soon, it is up to Sam to decide Earth's fate. Optimus urges Sam to put the AllSpark in his chest, which will destroy them both, but Sam instead inserts the cube into Megatron's chest, which kills him and destroys the AllSpark. All of the dead Transformer bodies are dumped into the Mariana Trench at Atlantic Ocean to be hidden, Sector 7 gets closed down by the President of the United States, and the Witwicky family are released from custody.Sam and Mikaela soon start a new relationship, and the film ends with Optimus Prime saying that the Autobots' fates have given them a new home: "Earth", and sends a message to all surviving Autobots to arrive on Earth.During the credits, Starscream is shown escaping into space.。
