Don't judge a book by its cover. We have heard that advice over and over again. And it makes sense. Why should we judge someone who is overweight simply by how they look? It has nothing to do with them as a person, and it says nothing about all they have achieved in life.
1.We should not judge them as healthy simply because they are thin.
We care so much about weight that we think those who succeed in keeping a "healthy weight" must be healthy.
Many studies have shown that being overweight increases the risk of diabetes, heart disease, and even death. 2. Some studies just look at pounds. Some use body mass index(BMI) which includes both height and weight measurements. But neither one says anything about overall health for sure.
In some studies, a person's fitness has been shown to be more important than overall weight.
That means those at "normal" weight, but below average fitness could be at higher risk than fitter and heavier people.3.
If you are thin and want to know if your health may be at risk, whole body MRIs (磁共振成像）can tell you if you are a TOFI (thin on the outside, fat on the inside). This is thought to increase your health risk even if you have a perfect body weight. 4. Rather, creating and keeping healthy lifestyle habits should be the goal.
Start now and you will be on your way to improving your overall health. 5.But even if it doesn't, rest assured you are still improving your health and your life.
A.The same holds true for thin people.
B.Weight loss will usually naturally follow.
C.The article mainly talks about people in Australia.
D.So weight loss should not be what we always dream of.
E.How many times do you say, "She looks great! Nice and thin!"?
F.But the problem lies with how we can know we are overweight.
G.So there is no such thing as healthy weight, only healthy lifestyles.
Sit still. It's the rule of every classroom. But that is changing as evidence builds that taking brief activity breaks during the day helps children learn and be more attentive in class, and a growing number of programs designed to promote movement are being adopted in schools. "We need to recognize that children are movement-based," said Brian Gatens, the superintendent of schools in Emerson, N.J." In schools, we sometimes are pushing against human nature in asking them to sit still and be quiet all the time.We fall into this trap that if kids are at their desks with their heads down and are silent and writing, we think they are learning," Mr. Gatens added. "But what we have found is that the active time used to energize your brain makes all those still moments better, or more productive."
A 2013 report from the Institute of Medicine concluded that children who are more active show greater attention, have faster cognitive processing speed and perform better on standardized academic tests than children who are less active. And a study released in January by Lund University in Sweden shows that students, especially boys, who had daily physical education, did better in school.
＂Daily physical activity is an opportunity for the average school to become a high-performing school," said Jesper Fritz, a doctoral student at Lund University and physician at the Skane University Hospital in Malmo who was the study's lead author.
＂Activity helps the brain in so many ways," said James F.Sallis, a professor of family medicine and public health at the University of California, San Diego, who has done research on the association between activity breaks and classroom behavior."Activity stimulates more blood vessels in the brain to support more brain cells.And there is evidence that active kids do better on standardized tests and pay attention more in school." "Plus," he added," it makes kids want to come to school more-it's fun to do these activities."
But not all districts are embracing the trend of movement breaks. "The bottom line is that with only six and a half hours during the day, our priority is academics," said Tom Hernandez, the director of community relations for the Plainfield School District in Illinois, about 40 miles southwest of Chicago. He said that under state law, the schools provide daily physical education classes and that teachers in the district find ways to give students time during the day to refresh and recharge.
＂Kids aren't meant to sit still all day and take in information," said Steve Boyle, one of the co-founders of the National Association of Physical Literacy, which aims to bring movement into schools." Adults aren't either."

In my senior year of high school, Mike and I were lined up in front of a small group of students made up mainly of the leaders of the senior classes. Our teacher said to us," The two of you will never amount to anything."
There was some snickering (窃笑)from some of the seniors as the teacher continued,"From now on,I am not going to waste any more time on either of you. I am only going to spend my time with these class leaders. You two are the class downs with bad grades, and you will never amount to anything. Now get out of here. "
That teacher did Mike and me the biggest favor of all. While what she said was true in many ways and her words hurt us deeply, her words also inspired both of us to work even harder. They carried us through college and into our own businesses.
A few years ago, Mike and I attended our high school reunion.It was nice to visit with people with whom we had spent three years during a period of time when none of us really knew who we were. It was also interesting to see that most of the so-called senior leaders had not become successful in the years after high school.
I tell this story because Mike and I were not academic whiz kids. We were neither financial experts nor athletic stars. For the most part, we were slow-to-average learners and students. In my opinion,we were not as naturally gifted as our fathers. Yet it was our teacher's stinging words and the snickering from our classmates that gave us the strength to move forward, to learn from our mistakes and to keep doing in both good times and bad times.
Just because you didn't do well in school, were not popular, bad in math, or have other reasons to underestimate yourself-none of them count in the long run. They only count if you think they count.
For those who're considering beginning your own financial fast track, you may have some doubts about your abilities. Trust that you have everything you need right now to be successful financially. All it takes to bring out your natural God-given gifts is your desire, determination and a deep faith that you have a genius and a gift that is unique.
1.What did Mike and I think of the teacher's words?
A.Her stinging words inspired them.
B.Her inspiring words hurt them deeply.
C.Her encouraging words helped them through bad times.
D.Her bitter words discouraged them from working harder.
2.At the school union,the author found _______
A.their former classmates didn't recognize him
B.it was boring to see their formers classmates
C.most of the class clowns turned out successful
D.most of the senior leaders didn't become successful
3.The underlined word "whiz" in Paragraph 5 means"
A.know-nothing B.slow
C.stupid D.genius
4.According to the author,which of the following people can achieve financial success?
A.Those who have faith in themselves
B.Those who did not do well in school
C.Those who have natural God-given gifts
D.Those who are doubtful about their abilities
Imagine turning on the GPS and seeing an image of your car from above. As the car drives, the map follows along in real time, informing you of any traffic, pedestrians, animals or other things nearby. Routes and names of road appear over the live stream. It's like the map has come to life.
This type of map isn't available yet. But it could be very soon. In 2014, the WorldView-3 satellite was sent into space. Even though it orbits Earth at more than 370 miles (600km) away, it can take images of objects on Earth that are just 10 inches (25cm) across. Looking all the way from outer space, it can make out a smart phone held in your hand. It can tell what types of cars are travelling down a road. But it can't identify your face or read the cars' license plate numbers.
According to some reports, this satellite and other US satellites have the technology to take even sharper images, with a resolution of up to around 4 inches (10cm). But US law forbids making these super-sharp pictures public. But the idea that anybody might be able to spy on the entire Earth in such detail may seem scary. Live, high-detail satellite mapping could be used to keep tabs on anybody at any time, without the person's knowledge. Ray Purdy of University College London told CNN that he couldn't imagine what this could mean for privacy. "Most satellites are commercially owned, so if you have money, you can have that imagery. It means anyone can spy on anyone." he said.
At the same time, live, detailed maps of the Earth's surface could aid humanity in amazing ways. Satellite images can help experts track storms as they form and chart their paths. At high detail, live maps of a disaster area could quickly reveal people in need of rescue as well as the safest routes in or out. Satellites images are already helping the police catch illegal fishing operations. Higher detail may make it possible to catch other criminals in the act. The images could also make it easier for farmers to watch over their crops or for scientists to find minerals. Also, these images play a very important role in monitoring the health of forests and other landscapes.
What do you think? Would you like to see everyone accessing high-detail live maps of the Earth's surface? Please share your idea with us on the website.
