Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.
Any owner will talk you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people-half of them pet owners-while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松) around pets, says Allen, who thinks it may be because pets don't judge.
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs-and found it worth doing.
Whether yellow, red or white, the onion is a vegetable that you may not know well. The list of its uses in cooking is endless. People have used onions to add taste to their foods for thousands of years. Besides onions' great taste, they are very good for you. They have special chemicals (化学物质) that improve your ability to fight off sickness and you have fewer chances of getting a sickness.
No matter how good onions are for you, it is difficult to cut an onion without your eyes filling with tears! When you cut into an onion, irritating (刺激性的) chemicals inside the onion will get into the air. They touch your whole eyes and cause pain. Your eyes make tears to wash away the chemicals and protect your eyes.
Luckily, cooks and scientists have discovered some ways to keep you from crying when you cut up onions:
{#blank#}1{#/blank#} The water will wash away the chemicals before they can reach your eyes.
{#blank#}2{#/blank#} The air will blow the chemicals away from your eyes.
{#blank#}3{#/blank#} This helps make the chemicals in the onion move slowly, so they may not ever reach your eyes. Also, this helps keep the onion fresh.
{#blank#}4{#/blank#} If you still cry while cutting onions, don't worry. Scientists think if you cut more onions, your body will become more resilient (适应的) to the onion's chemicals. So the tears will not last long. If you think about how healthy onions are, you might even call those tears "happy tears".
A. Try out these good ideas. B. Listen to music to relax yourself. C. Cut the onion under running water. D. Use a fan to blow air over the onion as you cut it. E. Put the onion in a fridge for an hour before cutting. |
Do you eat onions? What other vegetables do you think are healthy? Write down at least three.{#blank#}5{#/blank#}
By 2050, nearly 70%% of the world's population will live in cities. Many of them will become large cities with a population of more than 10 million. Moving people around each large city will he different. The traffic speed in Landon will fall about 7 miles per hour. Around the same speed it was 150 years ago, in the days of the horse and cart . But city planners are working on ways to solve the problem.
Self-driving taxis or robot taxis will play a part. There will be more than 30 million self-driving cars on the road by 2040. People don't need to drive by themselves. By 2050 there will be robot taxis in the city streets. We can call the taxis very quickly. |
Public transport like buses will be highly personalized.People don't need to look through the timetable. Buses will be connected on the Internet and make the way by themselves according to where the people need to go. |
Bikes will be helpful and safe, too. Cities could build special roads for them high above city streets.Xiamen in southeast China already has an 8-kilometer bicycle way to protect riders like that.That may be another kind of transport in 2050. It will be wonderful. |
