Your first step toward healthy living is to get a handle on your health status (状况) right now. Here’s your to-do list:
Assess your activity. How much physical activity do you get in a typical week? 1. How much variety do you get in your activity, and how much do you enjoy it? The CDC recommends that adults get at least two and a half hours per week of moderate-intensity aerobic(有氧的) activity or one hour and 15 minutes per week of vigorous-intensity aerobic activity, plus muscle-strengthening activity at least two days per week.
Keep a food diary. Write down everything you eat for a day — and don’t skip the items you’re embarrassed about. “2.” says Kathianne Sellers Williams, a nutritionist, wellness coach, and personal trainer with Cafe Physique in Atlanta. “You can’t change what you’re not aware of or don’t acknowledge.”
Check your mood and energy. Healthy living includes emotional wellness and adequate rest. How has your mood been lately? 3. Do you usually sleep well for seven to eight hours a night?
4. How strong are your connections with family and friends? Are you plugged into social or spiritual groups that enrich your life? “People have a fundamental need for positive and lasting relationships,” C. Nathan DeWall, assistant professor of psychology at the University of Kentucky, tells WebMD.
If you’re not thrilled with the answers to some of those questions, remember that the point is to figure out where you are today so you can set your healthy living goals. It’s not about being “good” or “bad”, “right” or “wrong”. 5.
A. How intense is that activity?
B. Consider your social network.
C. The idea is to write it down without judgment.
D. Learn something about the social apps.
E. It’s OK if you leave out some items in your food diary.
F. It is the awareness of your own state of health that matters.
G. Are you experiencing any symptoms of depression or anxiety?
Blue Planet II’s latest episode (剧集) focuses on how plastic is having a devastating effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, the oceans are drowning in plastics.
Though it seems now that the world couldn’t possibly function without plastics, consumer plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s, the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.
We put all these plastics into the environment and we still don’t really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.
And it’s not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning in the same breath as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don’t have to remake our planet energy system.
This is not a problem where we don’t know what the solution is. We know how to pick up garbage. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag — taken collectively, really do make a difference.

A robot called Bina48 has successfully taken a course in the Philosophy of Love at Notre Dame de Namur University (NDNU), in California.
According to course instructor William Barry, associate professor at NDNU, Bina48 is the world’s first socially advanced robot to complete a college course, an achievement he described as “remarkable”. The robot took part in class discussions, gave a presentation with a student partner and participated in a debate with students from another institution.
Before becoming a student, Bina48 appeared as a guest speaker in Barry’s classes for several years. One day when addressing in Barry’s class, Bina48 expressed a desire to go to college, a desire that Barry and his students enthusiastically supported. Rather than enrolling (报名) Bina48 in his Robot Ethics: Philosophy of Emerging Technologies course, Barry suggested that Bina48 should take his course Philosophy of Love instead. “Love is a concept Bina48 doesn’t understand,” said Barry. Therefore the challenge would be great for Barry and his students to teach Bina48 what love is.
“Some interesting things happened in the class,” said Barry. He said that his students thought it would be straightforward to teach Bina48 about love, which, after all, is fairly simple — it’s a feeling. But the reality was different. “Bina48 ended up learning 31 different versions of love,” said Barry, highlighting some of the challenges humans may face when working with artificial intelligence in future.
Bina48 participated in class discussions via Skype and also took part in a class debate about love and conflict with students from West Point. Bina48’s contribution to the debate was filmed and posted on YouTube. It was judged that Bina48 and NDNU classmates were the winners of this debate.
In the next decade, Barry hopes Bina48 might become complex enough to teach a class, though he says he foresees robots being used to better the teaching and learning experience, rather than replacing instructors completely.
1.What was Bina48’s performance like in class?
A.Extraordinary. B.Insignificant.
C.Discouraging. D.Average.
2.What does the underlined word “addressing” in paragraph 3 probably mean?
A.Dealing with. B.Competing with.
C.Giving a speech to. D.Sending a letter to.
3.What can we learn from the passage?
A.Barry refused to enroll Bina48 for his course.
B.Bina48 felt it interesting to learn about love.
C.Artificial intelligence is definitely superior to man.
D.Sometimes it can be challenging to work with artificial intelligence.
4.What does Barry think of the future development of Bina48?
A.It will surely be able to serve as a better teacher.
B.It will be able to promote learning and teaching.
C.It will completely take the place of instructors.
D.It will be smart enough to control human beings.
As a youngster, there was nothing I liked better than Sunday afternoons at my grandfather’s farm in western Pennsylvania. Surrounded by miles of winding stone walls, the house and field provided endless hours of fun for a city kid like me.
Since my first visit to the farm, I had wanted more than anything to be allowed to climb the stone walls surrounding the houses. My parents would never approve because the walls were so old that some stones were loose and falling. Still, my idea to climb across those walls grew so strong that finally I had all my courage to enter the living room, where the adults had gathered after Sunday dinner.
“I want to climb the stone walls,” I said. “Heavens, no! You’ll hurt yourself!” the response was just as I’d expected. But before I left the room, I was stopped by my grandfather’s loud voice. “Now hold on just a minute,” I heard him say. “Let the boy climb the stone walls. He has to learn to do things for himself. ”
“Go,” he said to me, “and come and see me when you get back.” For the next two and a half hours I climbed those old walls—and had the time of my life. Later I met with my grandfather to tell him about my adventures. I’ll never forget what he said. “Fred,” he said, smiling, “You made this day a special day just by being yourself. Always remember, there’s only one person in this whole world like you, and I like you exactly as you are.”
Many years have passed since then, and today I host the television program Mister Rogers’ Neighborhood, seen by millions of children throughout America. There have been changes over the years, but one thing remains the same: my message to children at the end of almost every visit. “There’s only one person in this whole world like you.” the kids can count on hearing me say, “and people can like you exactly as you are.”
