Leading a healthy life doesn’t only mean going to the gym and working out. It further means taking care of your body and making it easy to manage healthy choices in day-to-day life. 1.. Here are few tips to lead a healthier life.
Drink lots of water:
Water is very essential for our body to function. Most of us do not know that over 60% of our body is made up of water. It is very much needed in our body as it carries out body functions, removes waste and carries nutrients and oxygen around our body. We should take lots of water every day, as we lose water through daily activities.
Eat lots of fruits:
2.. Eating lots of fruits benefits our body with vitamins and minerals. For example-Oranges gives more health benefits than vitamin C pills. In order to lead a healthy life one must eat a plateful of nutritious fruits every day.
Exercise:
Exercising daily brings tremendous benefits to our body. Exercising increases the life span, lowers the risk of diseases, leads to higher bone density and helps in weight loss. 3.

Robot Surgeon (外科医生) Succeeds without Help from Human Doctors
Humans make mistakes. Even surgeons with years of experience are not infallible. But what if these doctors could pool their knowledge and experience together and create a surgical standard of care, to be carried out by machines?
That’s the idea behind surgical robots, which may soon perform most surgeries, from sewing up tiny wounds to performing heart procedures. Many of these operations are, in fact, already completed with the assistance of robots. But a recent test suggests that robots in the operating room may soon go a step further, performing on soft tissue completely on their own, from start to finish.
The Smart Tissue Autonomous Robot (STAR), successfully completed surgeries on pigs. “We’re the first group to develop autonomous robotic surgery with soft-tissue surgery, and when compared to standard operation, it’s better, ”says Peter Kim, professor of surgery. “The idea is not to replace surgeons; it will make the surgeons better and make the procedures safer.”
A recent Mayo Clinic study found that major surgical errors-including operating on the wrong site or side of the body, or even leaving tools or objects inside the patient-occur every one out of 22, 000procedures. That’s rare, but robots like STAR would aim to lower the number even further.
In the da Vinci surgical system, surgeons place their arms inside instruments and use their hands to control the movement of robotic tools on the operating table from afar. The robot’s every major move is controlled by surgeons, and thus its results may vary based on the surgeon’s training or experience.
STAR, on the other hand, is entirely autonomous. It’s not only able to work on its own and perform surgeries with a more flexible “hand”, but it’s able to react to the unexpected incidents. Cutting into hard tissue like bones is one thing, but operating on moving soft tissue is far more complex. STAR reacts to a changing environment, similar to how self-driving cars are programmed to not only drive on the highway, but also react to another driver making a mistake and getting in your way.
1.The underlined word “infallible” in Paragraph 1 probably means ________.
A. always right B. really creative
C. rather responsible D. quite smart
2.We can learn from the passage that STAR ________.
A. has been widely used in the operating room
B. can perform the operation on its own
C. can make surgeries much faster
D. will take the place of surgeons
3.In the da Vinci surgical system, ________.
A. robots are trained from afar
B. surgery results depend on surgeons
C. robots always make mistakes
D. surgeons have trouble controlling robots
4.In the last paragraph, the author mentions self﹣driving cars in order to show ________.
A. how bad getting in another driver's way might be
B. how difficult self﹣driving on the highway is
C. how smart an autonomous robot can be
D. how dangerous operating on people is.
When you eat fish, you probably eat it off a plate, using a fork. Well, the dolphins in Shark Bay, Australia, eat their fish from conch（海螺）shells!
Scientists have found some of these bottlenose dolphins（宽吻海豚）using their large beaks to trap fish in shells underwater. Then, carrying the shells to the surface, they shake out the fish into their mouths and eat them. Clearly, using the conch shells allows the dolphins to catch more fish than they would be able to without such a tool. The technique has been called “conching”.
Researchers noticed dolphins engaging in the behavior a handful of times from 2007 to 2009. This dolphin trend seemed to become popular.
Simon Allen, a scientist, was surprised to see the conching technique spreading. "In the lasts four months alone, the research team have seen and photographed the behavior no less than six times, possibly even seven," he said in a press release. He thinks the dolphins may be learning conching from one another.
Dolphins are known to be highly intelligent. The size of their brain is large in proportion（比例）to their body size. Compared with other animals, they have highly developed communication and social skills. This species of dolphin also uses other tools. They will break off pieces of sponges that grow in the ocean, for example, and use them to cover their beaks. This allows them to search for food on the ocean floor without hurting their noses.
Scientists are going to keep trying to catch the dolphins in the act of conching. They hope to see evidence of the dolphins teaching one another the technique. They also want to know how the dolphins get fish in the conch shell. Do they push the fish into the shell with their beaks? Or do they chase the fish into the shell before carrying them up to eat?
However they do it, Allen believes these dolphins to be particularly clever. "I wouldn't be too surprised to find such cunning ploys being adopted by Shark Bay's bottlenose dolphins," he said in statement.
1.The author develops the first paragraph by ______.
A. telling a story B. making n comparison
C. listing some facts D. offering an explanation
2.The technique "conching" refers to the fact that ______.
A. dolphins eat fish together with shells
B. dolphins attract fish with the conch shells
C. dolphins use shells to catch fish for food
D. dolphins catch fish with their beaks
3.According to Allen, the conching technique ______.
A. is spreading among sea animals quickly
B. has just been noticed at most 7 times
C. is sure to be learnt from one another
D. is becoming popular with dolphins
4.What might be the most suitable title for the passage?
A. Dolphins play a trick on each other
B. Dolphins use shells as tools to catch food
C. Dolphins depend on tools to find food
D. Dolphins are the cleverest sea creature
I was desperately nervous about becoming car-free. But eight months ago our car was hit by a passing vehicle and it was destroyed. No problem, I thought: we’ll buy another. But the insurance payout didn’t even begin to cover the costs of buying a new car－I worked out that, with the loan, we’d need plus petrol, insurance, parking permits and tax, we would make a payment as much as £600 a month.
And that’s when I had my fancy idea. Why not just give up having a car at all? I live in London. We have a railway station behind our house, a tube station 10 minutes’ walk away, and a bus stop at the end of the street. A new car club had just opened in our area, and one of its shiny little red Peugeots was parked nearby. If any family in Britain could live without a car, I reasoned, then surely we were that family.
But my new car-free idea, sadly, wasn’t shared by my family. My teenage daughters were horrified. What would their friends think about our family being “too poor to afford a car”? (I wasn’t that bothered what they thought, and I suggested the girls should take the same approach.)
My friends, too, were astonished at our plan. What would happen if someone got seriously ill overnight and needed to go to hospital? (an ambulance) How would the children get to and from their many events? (buses and trains) People smiled as though this was another of my mad ideas, before saying they were sure I’d soon realize that a car was a necessity.
Eight months on, I wonder whether we’ll ever own a car again. The idea that you “have to” own a car, especially if you live in a city, is all in the mind. I live—and many other citizens do too—in a place that has never been better served by public transport, and yet car ownership has never been higher. We worry about rising car costs, but we’d be better off asking something much more basic: do I really need a car? Certainly the answer is no, and I’m a lot richer because I dared to ask the question.
1.The author decided to live a car-free life partly because ______.
A. most families chose to go car-free
B. he was hurt in a terrible car accident
C. the cost of a new car was too much
D. the traffic jam was unbearable for him
2.What is the attitude of the author’s family toward his plan?
A. Supportive. B. Disapproving.
C. Optimistic. D. Unconcerned.
3.What did the author suggest his daughters do about their friends’ opinion?
A. Argue against it. B. Take their advice.
C. Think it over. D. Leave it alone.
4.What conclusion did the author draw after the eight-month car-free life?
A. Life cannot go without a car.
B. Life without a car is a little bit hard.
C. His life gets improved without a car.
D. A car-free life does not suit everyone.
