In today's world, English is the most wildly used language. It is our duty to learn English in the new situation of the reform and opening to the outside world. How can we master the English language? I'd like to give you some good advice.

    First, get interested in it. I enjoy listening to foreign friends talking when I was a child. At the same time I watched the English program Follow Me on TV. From then on, I kept on learning English. The more I learned, the more progress I made.

    Second, practice makes perfect. Many people study English very hard, but they are very shy to speak it in public, for they are afraid of making mistakes. Remember you have to make a mistake before you can correct it. A native English speaker makes mistakes sometimes, too.

    Third, the beginners should be encouraged to pay attention to idioms. The English language has many idioms. For example, you should say “ He is as strong as a cow.”

    When I was growing up，I was embarrassed to be seen with my father. He was badly crippled (跛脚)，and when we would walk together，his hand on my arm for balance，people would stare，I would be ashamed of the unwanted attention.

    It was difficult to walk together—and because of that，we didn't say much as we went along. But as we started out，he always said，“You set the pace. I will try to follow you.”

    Our usual walk was to or from the subway，which was how he got to work. He went to work sick，and even in bad weather. He almost never missed a day，and would make it to the office even if others could not. It was a matter of pride for him.

    When snow or ice was on the ground，it was impossible for him to walk，even with help. At such times my sister or I would pull him through the streets of Brooklyn，N.Y.，on a child's sleigh to the subway entrance. Once there，he would try to grasp handrail until he reached the lower steps that the warmer tunnel air kept ice free. In Manhattan the subway station was the basement of his office building，and he would not have to go outside again until we met him in Brooklyn on his way home.

    When I think of it now，I am surprised at how much courage it must have taken for a grown man to suffer from shame and disability. And I am also surprised at how he did it—without bitterness or complaint.

    He never talked about himself as an object of pity，nor did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”，and if he found one，the owner was good enough for him.

    Now that I am older，I believe that is a proper standard by which to judge people，even though I still don't know exactly what a “good heart” is. But I know the times I don't have one myself.

    He has been away for many years now，but I think of him often. I wonder if he sensed my reluctance to be seen with him during our walks. If he did，I am sorry I never told him how sorry I was，how unworthy I was，how I regretted it. I think of him when I complain about my troubles，when I am envious of another's good fortune，when I don't have a “good heart”．

    July is a month of fun-filled activities for kids and teens as long as you know where to find them. When you want some fun activities for July, consider these ideas happening in this month.

    Good health is the most valuable thing in the world. When you've got it, you never think about it. When you haven't got it, you think about it all the time. Our biggest enemies are not terrible diseases and so on. We are our own biggest enemies because we sometimes destroy our own good health. Some of us eat too much, drink too much and smoke too much. And though our reason tells us we should control ourselves, we find it difficult. The fact is that most human beings need stimulation (刺激). Who doesn't enjoy a drink after a busy day? Only a smoker knows the pleasure of a cigarette with a cup of coffee.

    The danger is when these innocent pleasures run our lives and so destroy our health. When you find yourself eating between meals or eating too much rich food, when you can only keep yourself going by taking frequent drinks or by smoking one cigarette after another, then it's time to stop and think what you might be doing to yourself. The funny thing is that when we don't control ourselves, simple pleasures are no longer simple pleasures.

    All right, I know what you're thinking. You're probably saying, “It's easy to say, but I can't help myself. I need that extra bit of food, that extra drink, that extra cigarette. Life has so many pleasures that I can't do without them.” But I'm saying you can help yourself. Not only that, you must help yourself. Because if you don't help yourself, no one else can. So be your own best friend.

    Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you'll have no trouble answering these questions.

    Most of us observed much more as children than we do as adults. A child's day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的）to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.

    The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they'd felt cold water at first.

    Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.

    The pressures of "time" and "destination" are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what's around them. I asked them what they'd seen. "Oh, a few birds," they said. They seemed bent on their destinations.

    Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.

    It started during a yoga class. She felt a strange pull on her neck, a feeling completely foreign to her. Her friend suggested she rush to the emergency room. It turned out that she was having a heart attack.

    She didn't share similar symptoms with someone who was likely to have a heart attack. She exercised, watched her plate and did not smoke. But on reviewing her medical history, I found that her cholesterol (胆固醇) level was sky-high. She had been prescribed a cholesterol-lowering statin (他汀) medication, but she never picked up the prescription because of the scary things she had read about statins on the Internet. She was the victim of fake medical news.

    While misinformation has been the object of great attention in politics, medical misinformation might lead to an increase in deaths. As is true with fake news in general, medical lies tend to spread further than truths on the Internet—and they have very real bad consequences.

    False medical information can also lead to patients experiencing greater side effects through the "nocebo effect (反安慰剂效应) ". Sometimes patients benefit from an intervention (干预) simply because they believe they will—that's the placebo effect (安慰剂效应). The nocebo effect is the opposite. Patients can experience harmful effects because they anticipate them. This is very true of statins. In blinded trials, patients who get statins are no more likely to report feeling muscle aches than patients who get a placebo. Yet, in clinical practice, according to one study, almost a fifth of patients taking statins report side effects, leading many to discontinue the drugs.

    What else is on the fake news hit list? As always, vaccines (疫苗) . False concerns that the vaccine may cause side effects have greatly reduced coverage rates.

    Cancer is another big target for pushers of medical misinformation—many of whom refuse alternative therapies. "Though most people think cancer tumors are bad, they're actually the way your body attempts to contain the harmful cells," one fake news story reads. It warns that prescription medications lead to the uncontrolled cell mutations (变异) .

    Silicon Valley needs to face this problem. I am not a free-speech lawyer, but when human health is at risk, perhaps search engines, social media platforms and websites should be held responsible for promoting or hosting fake information. Meanwhile, journalists should do a better job of spreading accurate information.
