Teenagers who spend hours in front of the television may have a poorer diet as young adults．
A study， which involved nearly 1，400 high school students found those who watched TV for five hours or more every day had less healthy diets than other students five years later． Why does this happen？ Should the parents take any measures？
On the one hand， people who spend a lot of time in front of the TV， especially teenagers， may snack （吃零食） more， and that may influence their long-term diet quality．
On the other hand， TV ads for fast food， sweets and snacks make teenagers eat more of those foods． TV time might also replace exercise time for some kids．
The researchers found a clear relationship between TV time during high school and diet quality of the young． While the heaviest TV viewers were eating the most junk food， those who'd watched fewer than two hours every day had the most fruits and vegetables．
As far as I am concerned， children should watch no more than two hours of television per day． And parents should set a good example by eating right， being physically active and curbing their own TV time．
1. According to the passage， heavy TV viewers are easy to ______ ．| A．eat more fruits |
| B．eat fewer vegetables |
| C．eat less junk food |
| D．eat more food high in calcium （钙） |
| A．adding | B．checking |
| C．controlling | D．stopping |

【推荐1】Dad grew a lot of vegetables in the garden. Dates when everything was planted and the weather were all carefully recorded. Mum really wanted a holiday or a trip out for the day,but Dad would say, “It’s too warm today. My vegetables will need a drink every three hours.”
Then Dad discovered the local Loxton show—finally somewhere he could show off his gardening skills after his retirement. The first year he took part, he entered just four of his specimens (样品). Much to his surprise, he won three firsts and a second. We all thought this was great and eating free prize-winning vegetables was even better. Mum wasn’t so sure. “He gets up so early and spends hours getting them ready,” she complained (抱怨). We reminded Mum that it was a really cheap hobby, not to mention all the fresh vegetables that appeared out of the backyard. “You try freezing 15 kilos of beans,” she said. “I don’t care how expensive they are in the supermarket; I never want to see another bean again.”
But she loved the praise she got from her friends about how excellent her husband was and how lucky she was to have all these fresh vegetables. “I can’t let him know about that; he might get a big head,” she said with a smile. “So I’ll just complain a bit instead.”
Then over the following three years, Dad entered even more vegetables for the show and brought lots of first prizes home. But Mum got a little tired of the whole process of staying up half the night preparing his prize-winning vegetables. Dad finally said on his 75th birthday, “I have decided that this year I won’t enter the show. It’s not fair to everyone else who enters if I just keep winning year after year. Three years in a row is enough for me lo knew I grow the best vegetables.”

【推荐2】Following Christmas dinner, my family was relaxing around the table. We had all enjoyed traditional turkey and sweet potatoes lightly shining with brown sugar. The good cooking smells still filled the air; and the oven remained warm. My sister, our chef, was enjoying the admiration.
My nephew, never one to sit still for long, began dribbling (运球) his basketball around the table. Upon nearing Dad, he stopped — almost uncertainly. With shaking wrinkled hands, Dad had reached out for the ball. The boy, confused, looked up and over at us.
I watched my father closely to see what he would do. The twinkle in his eyes shone brighter than any Christmas lights. Holding the ball and reaching forward with a playful smile, Dad bounced it and then caught it.
This action was repeated. Gently throwing the ball away, Dad began a game of catch. The ball continued to be passed through eager pairs of outstretched hands. Cries of “Over here!” rang through the warm kitchen. Dad’s active participation was remarkable to me, for he had advanced Alzheimer’s disease, which had robbed him of many memories and the recognition ability. Despite this, Dad clearly recognized the ball and what you could do with it.
In my younger years, playing with Dad was rare. To his credit, Dad worked hard and provided for us. He was very private and never showed nor shared much emotion; his game of choice was chess, which he did eventually teach me how to play. As an adult, I had become a caregiver as Dad declined. Connecting moments between father and son had been few and far between before he took the basketball.
I’m not sure how long we played catch. What I do know is that our game ended all too soon, and it was time to face the reality of dirty dishes piled high on countertops. The moment, though, will certainly last forever.

【推荐3】When Brad Ryan was young. He used to spend a good time with his grandma Joy, Ryan says, “I remember sleepovers at her house when she would teach me to make cookies.”
The two became distant (遥远的) when Ryan’s parents divorced (离婚), but then ran into each other 10 years later. Realizing how much he liked his grandmother and missed that lost time, he made a plan to spend time with her.
About eight years ago, Ryan was telling Joy about his 2009 hike and many adventures living in the wilderness, “Her eyes softened and then she matter-of-factly said, ‘I regret that I didn't get to see more things in life. It would have been nice to see the mountains,’” Ryan recalls. “My heart broke for her.”
It wasn’t until a few years later that the two took a trip to the Great Smoke Mountains. After a stressful work schedule. Ryan needed an escape to nature. So he invited his grandma to travel with him. They arrived late at night in the rain with Joy holding the umbrella while Ryan set up the tent. At 85, she had never slept in a tent before, but she climbed 2.3 miles on a trail, receiving high-fives all the way.
“It was a life-changing trip that provided more purpose than anything I had ever done,” Ryan says. “Two years later I set up a GoFundMe called Grandma Joy’s Road Trip in the spirit of making up for lost time and proving that you're never too old to pack in a lifetime of adventure and travel.”
In the past four years, they're travelled more than 25,000 miles across 38 states. So far, they’ve visited 29 of the 61 US national parks, with much of the adventure documented on Instagram.
“You never know what’s going to come out of her mouth, and it's usually interesting. I wouldn't want to travel the country with anyone else at this point. Of course we bet tired and have our angry moments. There have been difficult moments that we had to work through, but finally we get to where we need to be.”

Bacteria are the one of the main food poisoners. So, to get food on the table safely, you need to know and follow the rules for food care.
KEEP FOOD HOT
High food temperatures (165°F to 212°F) reached in boiling, baking, frying, and roasting kill most food poisoning bacteria. If you want to delay serving cooked food, though, you have to keep it at a holding temperature — roughly 140°F to 165°F. Steam tables and chafing dishes are designed to maintain holding temperatures. But they don’t always keep food hot enough. So it’s not wise to leave hot food out more than 2 hours.
When cooked food is left out unheated, the possibility of bacterial growth is greater, since the food quickly drops to room temperature where food poisoners multiply.
To serve hot foods safely — particularly meat and poultry, which are highly affected by food poisoning — follow these rules:
• Cook thoroughly — Cook meat and poultry to the “doneness” temperatures given in the above chart. To make sure that meat and poultry are cooked all the way through, use a meat thermometer (温度计). Insert the tip into the thickest part of the meat, avoiding fat or bone.
• Don’t interrupt cooking — Cook meat and poultry completely at one time. Partial cooking may encourage bacterial growth before cooking is complete.
• Cooking frozen food - Allow frozen food more time to cook — generally 1.5 times the period required for food that has been thawed (解冻).
1. At what temperature do bacteria grow the fastest?| A．40ºC~ 60ºC. | B．60ºF~125ºF. | C．40ºC~ 140ºC. | D．125ºF~140ºF. |
| A．hot food should not be left out over two hours. |
| B．frozen food should be thawed with a microwave oven. |
| C．raw ham should be cooked to the “doneness” temperature at 71ºF. |
| D．steam tables and chafing dishes should be used to keep food hot enough. |
| A．The only way to ensure food safety is to keep it hot enough. |
| B．High food temperatures above 74ºC destroy most poisoning bacteria. |
| C．Compared with goose, ground beef should be cooked to higher temperatures. |
| D．Insert the tip of a thermometer into the thickest part of the fat to control the temperature. |

【推荐3】Healthy eating doesn't just mean what you eat, but how you eat. Here is some advice on healthy eating.
Eat with others. It can help you to see others' healthy eating habits. If you usually eat with your parents, you will find that the food you eat is more delicious.
Listen to your body. Ask yourself if you are really hungry. Have a glass of water to see if you are thirsty—sometimes you are just thirsty, you need no food. Stop eating before you feel full.
Eat breakfast. Breakfast is the most important meal of the day. After you don't eat for the past ten hours, your body needs food to get you going. You will be smarter after eating breakfast.
Eat healthy snacks like fruits, yogurt or cheese. We all need snacks sometimes. In fact, it's a good idea to eat two healthy snacks between your three meals. This doesn't mean that you can eat a bag of chips instead of a meal.
Don't eat dinner late. With our busy life, we always put off eating dinner until the last minute. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest most of the food before you rest for the next 8-10 hours.

【推荐1】Experts analyzed how language can affect children’s lives and the role it plays in everyday life They also determined which languages tend to lead to the best career opportunities as an adult. “We believe that language learning is hugely beneficial for children’s development and it is a real investment for the future,” said Antonella Sorace, professor of developmental linguistics (语言学) at Edinburgh University. The study involved a survey of 2,001 parents with children under the age of 18, as well as another survey of more than 500 business leaders.
So which languages took the top spot? Results indicated that children should be learning French, German, and/or Chinese if they want to be successful within the next ten years. Mastering a second language opens the door to new markets for businesses and allows them to create new relationships with potential partners. Besides being able to speak another language, the academic and interpersonal skills that can be acquired from learning a new language are important as well. “Children who are exposed to different languages become more aware of different cultures, other people, and other points of view. They also tend to be better than monolinguals (只用单语的人) at multitasking and are often more advanced readers,” said Sorace.
A vast majority of parents surveyed in this study (85 percent) believe it is important for their children to learn a second language, and about one in four believe it will increase their child’s career opportunities and improve their chance of being employed. The future employment markets are in need of space tour guides, robot coaches, front-line e-commerce workers, nurses etc. No matter what a child choose to be, multilinguals and cross-culture talents will probably have a good chance to take the lead. However, 45 percent of parents surveyed admit that their child or children cannot speak a second language.
If you want your child to stand out from the crowd, follow the habits of parents of successful people-give children chores, set high but realistic expectations, get yourself educated, make time for bonding, accept and recognize their feelings—and, of course, make sure they learn one of the three success languages!

People have strange ideas about food. For example, the tomato is a kind of very delicious vegetable. It is one of useful plants that can be prepared in many ways. It has rich nutrition and vitamin in it. But in the 18th century, Americans never ate tomatoes. They grew them in their gardens because tomato plants are so pretty. But they thought the vegetable was poisonous (有毒的). They called tomatoes “poison apples.”
President Thomas Jefferson, however, knew that tomatoes were good to eat. He was a learned man. He had been to Paris, where he learned to love the taste of tomatoes. He grew many kinds of tomatoes in his garden. The President taught his cook a way for a cream of tomato soup. This beautiful pink soup was served at the President’s party.

【推荐3】Many cultures around the world have a grain that is not grown or even known outside its home area. Now, a staple grain native to Ethiopia, teff, is appearing on grocery shelves in America.
Teff has been an important part of the Ethiopian diet for thousands of years. Like rice and wheat, it is a cereal grass. Teff is known for its fine grain and used mainly to make flour. Teff flour is the key ingredient in injera, the large, spongy pancakes that make up a large portion of the Ethiopian diet.
Teff was introduced to the United States by a man named Wayne Carlson, who learned about teff while doing public health work in Africa in the mid-1970s. "I came to know teff because I was eating it all the time and hosted by teff farmers. " he said. In the late 70s, Carlson returned to the U. S. , married and settled in southwest Idaho. Then he came up with an idea to introduce teff grass to his home state. " Geologically, it is very similar to Ethiopia."
Wayne and his wife Elisabeth are not farmers, nor do they want to be. So they convinced actual farmers in Idaho to grow teff on contract for them. The Carlsons milled it themselves.
Wayne went through the Washington, D. C. telephone book and looked for the names that were Ethiopian. And that is how the business slowly grew. Over time, the Teff Company has outgrown four different mills.
Rich Roseberg is a food researcher at Oregon State University. He says teff production has exploded over the past decade in the U. S. He says most teff grown in the U. S. is fed to farm animals. In Idaho, however, where the Carlsons are based, Roseberg believes more of the teff production is for human food. Teff contains lots of calcium, iron, protein and fiber. Roseberg credits Wayne Carlson for being ahead of his time.

【推荐1】Extreme sports are any sport that involves great speed, height and danger. You need to be very fit to take part in these sports. It can be quite expensive because a lot of special equipment is needed. This type of sport is not usually a team sport like football or rugby. It is what is known as an individual sport because you are alone most of the time.
BASE JUMPING: This is the sport of using a parachute(降落伞) to jump from fixed objects like skyscrapers, high towers, bridges, domes, statues and steep, high mountains. Base jumping can be very dangerous as you compete to be the quickest to reach solid ground.
SKY DIVING: This sport also uses a parachute. Divers are taken up to a certain height in an aeroplane. They have parachutes strapped to their backs. They then jump out of the plane and freefall before opening their parachute at the correct moment. The parachute is to stop them from hitting the ground at a great speed, which would be very dangerous. The most important thing about this sport is knowing when exactly to open the parachute.
ROCK CLIMBING: This is the activity of climbing up and down very steep rock formations. This sport needs special equipment to keep the climbers safe. A climber has to have great strength of body and mind. It is better to climb in small groups, so that there is someone to help in the case of an emergency.
ICE CLIMBING: This is almost the same as rock climbing. The difference is that the climbers are climbing up and down steep walls of ice, such as frozen waterfalls. Special equipment is needed to keep climbers safe. Ice climbing is quite dangerous because ice changes as it melts or freezes. It is really difficult to know exactly how hard or how soft ice will be. Ice breaks easily so climbers need to concentrate very hard when they are climbing.
These are the sports on offer at Shanghai School of Extreme Sports. Now you have to decide which one you would like to do.

【推荐2】Americans are proud of their variety and individuality, yet they love and respect few things more than a uniform, whether it is the uniform of an elevator operator or the uniform of a five-star general. Why are uniforms so popular in the United States?
Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian clothes. People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears uniform tends to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity than to step out of uniform?
Uniforms also have many practical benefits. They save on other clothes. They save on laundry bills. They are tax-deductible (可减税的). They are often more comfortable and more durable than civilian clothes.
Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement. When people look alike, they tend to think, speak, and act similarly, on the job at least.
Uniforms also give rise to some practical problems. Though they are long-lasting, often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes.

【推荐3】Bridging the gap between simple automation(自动化)and robots that can communicate with humans naturally is a big challenge, but major progress has been made in the past few years.
Research into social robots has shown that machines that respond to emotion(情感)can help the elderly and children, and could lead to robots becoming more widely socially acceptable.
Milo is both a robotic teacher and a student. Developers RoboKind created Milo to help children with autism(自闭症)learn more about emotional expression and empathy (共鸣) while collecting data on their progress to target learning and treatment. Milo's friendly face makes himself kind and the children are able to read his expressions.
Robots can also reduce stress in hospital settings. Expper Tech's Robin was designed as a robot to provide emotional support for children with medical treatment. Robin explains medical details to them, plays games and tells stories, and during treatment draws their attention away to reduce their feeling of pain.
Expper's robot uses Artificial Inteligence(AI) to create empathy, remembering expressions and conversations to build conversation for follow-up sessions. In trials at the Wigmore Medical Pediatric Clinic in Yerevan. Armenia, the team found that Robin led to a 34% weakening in stress and improve happiness of 26% in the 120 children who interacted(互动)with him at least once.
Today's simple systems are being trained to meet that demand. This includes ProxEmo, a little wheeled robot that can guess how you are feeling from the way you walk, and ENRICHME who helps older people to stay physically and mentally active. The problem is the fear that human jobs may be lost as robots become better at dealing with social situations.
