It’s hard to do much to treat a cold or the flu once you’re infected. As with many illnesses, taking steps towards prevention may be the best cure for the cold or flu.
Wash your hands. One of the easiest and most effective measures to prevent colds and the flu is by washing your hands thoroughly and frequently. This reduces the proliferation of bacteria and the cold or flu virus from common spaces or surfaces.
Cover your nose and mouth. Put your hand or tissue (纸巾) over both your nose and mouth whenever you cough or sneeze. Covering sneezes and coughs lowers the risk of spreading your germs (细菌) and the viruses.
Get enough rest. Making sure that you allow your body to rest can ease your symptoms and help you more quickly recover from a cold or the flu.
| A．Avoid the crowd. |
| B．Don’t share items with sick people. |
| C．Make sure you wet hands before applying soap to your hands. |
| D．Stay home from work or school, especially if you have a fever. |
| E．Throw away the used tissue immediately and then wash your hands. |
| F．A cold is a viral infection that causes discomfort in the nose and throat. |
| G．You can help prevent common viruses with careful attention to your habits. |

【推荐1】In 2013, Gabby Frost founded Buddy Project when she was 15. At that time her best friend had been diagnosed (诊断) with a mental health condition, and that was the first time she was made aware of what mental illness was. She wanted to learn more and develop a good support system for her.
Mental illness affects tens of millions of people in the United States each year, yet only half receive treatment, according to the National Institutes of Mental Health. Buddy Project’s website says the service is not a substitute for therapy or other types of mental health care, and that it directs people to resources for further help.
Since founding the organization as a high school student, Frost has helped more than 200,000 participants find a new friend. On the day when Buddy Project was launched, she used her powerful social media presence to attract nearly 3,000 participants. “This was around the time when teens really began talking about mental health and found a supportive community online to talk about it,” she said.
One of the biggest social barriers she had to jump over was that people didn’t view her seriously because she was a 15-year-old girl, and even now, she’s still a young woman. “Sometimes it’s frustrating because people don’t think what I do is needed or they don’t think I’m professional,” she said. “Most people are blown away that a 20-year-old girl is running this and that it’s one person doing this but not a whole team. I’m just lucky that I’ve found a support system that has been able to help my mum and me with the project.”

【推荐2】I developed postpartum depression (PPD) (产后抑郁症) after giving birth to my first son.Actually, I started feeling bad before I even had my son. It started with severe anxiety about doctors' appointments.
The night I arrived home after giving birth, I had my first panic attack. I doubted I was having a slight heart attack. The next day, a public health nurse visited our home to see if everything was fine with me- whether I had a heart attack or suffered anything else or I was just all alright. She reassured me that I didn't have a heart problem, and informed me that it was likely a panic attack. The nurse visit was part of a program that provided support for new moms. Sadly, it didn't include any information on PPD.
By my six-week postpartum checkup, I knew something was wrong. I was having difficulty falling asleep and I felt like I was slowly going crazy. Panic attacks were more frequent. I talked with my obstetrician (产科医师)，but unfortunately, she was not trained to recognize or cure PPD. Now I didn't know whom to turn to for help.
I told my situation to my mom and my husband but they didn't understand what I was really experiencing. They figured that being a new parent was tough for anyone, so feeling a little down after giving birth- “baby blues" was just normal and not necessarily a sign of depression. But my cousin, also a new mom, knew me well, and she could see that something was wrong.
With my cousin's encouragement, I went to see my family doctor and I was finally diagnosed(被诊断为)with PPD. I started taking medication, and began to feel better. Eventually, I rehabilitated, feeling like my old self again.
It is common for new moms to get the“baby blues" mixed up with PPD. The early symptoms are similar, so it can delay a diagnosis because you think the feelings will go away. I do think more attention should be drawn to the letter. After all, a new research finds that about 1 in 7 new mothers will be seriously troubled by PPD.

【推荐3】Artificial intelligence (AI) technology may soon be a useful tool for doctors. It may help them better understand and treat diseases like liver cancer in ways that were never before possible.
Rishi Rawat, who teaches AI at the University of Southern California in Los Angeles, is part of a team of scientists researching how AI and machine learning can more easily recognize cancerous growths in the liver. Rawat provides information about cancer cells to a computer. He says, “You can put the data into them and they will learn the patterns and the pattern recognition that’s important for making decisions.”
David Agus is another researcher. He believes that machines are not going to take the place of doctors. “Computers will not treat patients, but they will help make certain decisions and look for things that the human brain can’t recognize by itself.”
Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on the kind of cancer. Nowadays, researchers take a thin piece of tissue(组织), put it on a small piece of glass and add color to see the cells better. That process could take days or even longer. Scientists say artificial intelligence can do something better than just count cells. Through machine learning, it can recognize complex patterns or structures, and learn how the cells are organized.
The hope is that machines will soon be able to make a quick identification of cancer that is free of human mistakes. Agus says the process could be done for almost no cost in the developing world and that having a large amount of information about patients is important for a machine to effectively do its job in medicine.
The researchers of the university are now only studying liver cancer. But doctors predict artificial intelligence will one day make a difference in all forms of cancer.

【推荐1】“Old wives tales" are beliefs passed down from one generation to another. For example, most of us remember our parents' telling us to eat more of certain foods of not to do certain things. Is there any truth in these teachings? Some of them agree with present medical thinking, but others have not passed the test of time.
Did your mother ever tell you to eat your carrots because they are good for your eyes? Scientists now report that eating carrots can help prevent a serious eye disease called macular degeneration. Eating just one carrot a day can reduce the possibility of getting this disease by 40%. Garlic(蒜）is good for you ,too. It can kill the type of virus that causes colds.
Unfortunately, not all of Mom's advice passed the test of medical studies. For example,generations of children have been told not to go swimming within an hour after eating. But research suggests that there is no danger in doing so. Do sweets cause tooth problems? Well, yes and no. Sticky sweets made with grains tend to cause more problems than sweets made with simple sugars.
Even though science can tell us that some of our traditional beliefs don't hold water , there is still a lot of truth in the old wives' tales.After much of this knowledge has been accumulated （积累)from thousands of years of experience in family health care.

【推荐2】Tips for Running in the Morning
There are so many great reasons to run in the morning. It's a great way to wake up and watch the world awaken with you. This is not to suggest that getting into the habit is easy, especially if you're not a morning person. But there are ways to ease you into the routine and in ways you may even enjoy.
◆Teach Yourself Good Sleep Habits
Building a morning running habit starts with a good night's sleep. According to the American Sleep Association, you can train yourself to sleep at an earlier hour if you：
·Plan to go to sleep at the same time every night.
·Avoid TV, reading, or electronic devices an hour before bedtime.
·Avoid coffee or alcohol three hours before bedtime.
·Have a nightly routine, such as a warm bath, meditation (冥想), or listening to calming music.
◆Sleep in Your Running Clothes
It's hard to blow off a run when you're already dressed for it. If you really want to get a jump start and find motivation as soon as you open your eyes, simply wear your running clothes to bed.
◆Put Your Alarm Clock out of Reach？
When your alarm clock goes off early in the morning, you may want to get a couple of more minutes' sleep. If you're struggling to get up, place the alarm clock across the room so that you have to get out of bed to turn it off. The more steps you put between you and the bed, the less likely you are to fall back asleep.
◆Eat Smart
It is never good to run on an empty stomach. After a long night's sleep, you have little to draw upon in the way of energy. If you head out the door having eaten nothing at all, you will likely experience tiredness, muscle pain, shortness of breath, and weakness. Worst yet, you may convince yourself that you're “not made for morning runs，” when, in fact, you're not feeding yourself properly.
