The freezing Northeast hasn't been a terribly fun place to spend time this winter, so when the chance came for a weekend to Sarasota, Florida, my bags were packed before you could say “sunshine”. I left for the land of warmth and vitamin C(维生素C), thinking of beaches and orange trees. When we touched down to blue skies and warm air, I sent up a small prayer of gratefulness. Swimming pools, wine tasting, and pink sunsets(at normal evening hours, not 4 in the afternoon) filled the weekend, but the best part - particularly to my taste, dulled by months of cold- weather root vegetables- was a 7 a.m. adventure to the Sarasota farmers' market that proved to be more than worth the early wake-up call.

           The market, which was founded in 1979, sets up its tents every Saturday from 7:00 am to 1 p.m., rain or shine, along North Lemon and State streets. Baskets of perfect red strawberries; the red-painted sides of the Java Dawg coffee truck; and most of all, the tomatoes: amazing, large, soft and round red tomatoes.

Disappointed by many a broken, vine-ripened(蔓上成熟的) promise, I've refused to buy winter tomatoes for years. No matter how attractive they look in the store, once I get them home they're unfailingly dry, hard, and tasteless. But I homed in, with uncertainty, on one particular table at the Brown's Grove Farm's stand, full of fresh and soft tomatoes the size of my fist. These were the real deal- and at that moment, I realized that the best part of Sarasota in winter was going to be eating things that back home in New York I wouldn't be experiencing again for months.

Delighted as I was by the tomatoes in sight, my happiness deepened when I learned that Brown's Grove Farm is one of the suppliers for Jack Dusty, a newly opened restaurant at the Sarasota Ritz Carlton, where - luckily for me - I was planning to have dinner that very night. Without even seeing the menu, I knew I'd be ordering every tomato on it.

    Lima, the capital of Peru (秘鲁), has countless museums that tourists can't afford to miss. Now start packing up and prepare for your perfect Peruvian history exploration at these wonderful museums.

    ◆Larco Museum

    Stepping inside, visitors get to learn the 5,000-year history of Peru through an unbelievable collection of objects. The best thing about the museum is that it keeps the door to the storeroom open to visitors so that they can admire its collection closely.

    ◆Gold Museum of Peru

    If you like shiny objects or precious metals, then plan a trip to the Gold Museum of Peru. In ancient times, the Peruvian people were celebrated for their skills in metals. And the museum is aimed at preserving this heritage.

    ◆Lima Art Museum

    Art experts are much pleased as the city is also home to the Lima Art Museum. Its permanent exhibit of over 1, 200 pieces is merely a small part of its amazing collection of more than 17, 000 artifacts. The highlight of the museum is its collection of Carlos Baca-Flor's masterpieces, which is considered to be the most complete set in the world.

    ◆Museum of Italian Art

    The only museum dedicated to European art in Peru, the Museum of Italian Art is a storehouse of classical and contemporary paintings and sculptures belonging to the 20th century. The property is easily accessible by a short walk from the Lima Art Museum.

    ◆Museum of Natural History

    Last but certainly not least is the Museum of Natural History. Giving a glimpse into the rich biodiversity in Peru, the museum has on display the skeletons of a sperm whale and fossils of several mammals.

    Warford is an optometrist (验光师) in Florida. He has seen an increase in "computer vision syndrome (电脑视力综合症)"in children. "A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort, or because their nearsightedness appears to be increasing and they're worried," he says.

    Dr. Watford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults. "Even if their eyes start to feel uncomfortable or they start to get a headache, they're less likely to tell their parents, because they don't want to have the game or whatever taken away," he explains.

    He says another part of the problem is that people blink (眨眼) less often when they use digital devices. He says, "A person who uses an electronic device blinks about one third as much as we normally do in everyday life. And that can result in the front part of the eye drying and not staying protected like normal."

    Eye doctors offer suggestions like the 20 /20 /20 rule. That means every twenty minutes look away twenty feet or more for at least twenty seconds from whatever device you're using.

    Other suggestions include using good lighting and spending less time looking at screens. Many experts say children should spend no more than two hours a day using digital devices—with no screen time for children under two.

    But not all eye doctors have noticed an increase in problems in children. Dr. David Hunter, for instance, says, "While it is possible to develop fatigue looking at screens for a long time, there's certainly no proof that it actually causes any damage to the eyes."

    The Healthy Habits Survey (调查) shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

    ①How many times did you brush your teeth yesterday?

    ·Finding: A full 33% of seniors brush their teeth only once a day.

    ·Step: Remove the 300 types of bacteria (细菌) in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

    ②How many times did you wash your hands or bathe yesterday?

    ·Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number doctors recommend.

    ·Step: We touch our faces around 3, 000 times a day—often inviting germs (病菌) to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

    ③How often do you think about fighting germs?

    ·Finding: Seniors are not fighting germs as well as they should.

    ·Step: Be aware of germs. Do you know it is not your toilet but your kitchen sponge (海绵) that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

    Memory, they say, is a matter of practice and exercise. If you have the wish and really make a conscious(自觉的) effort, then you can quite easily improve your ability to remember things. But even if you are successful, there are times when your memory seems to play tricks on you.

    Sometimes you remember things that really did not happen. One morning last week, for example, I got up and found that I had left the front door unlocked all night, yet I clearly remember locking it carefully the night before.

    Memory "tricks" work the other way as well. Once in a while you remember not doing something, and then find out that you did. One day last month, for example, I was sitting in a barber shop waiting for my turn to get a haircut, and suddenly I realized that I had got a haircut two days before at the barber shop across the street from my office.

    We always seem to find something funny and amusing in incidents caused by people's forgetfulness or absent-mindedness. Stories about absent-minded professors have been told for years, and we never get tired of hearing new ones. Unfortunately, however, absent-mindedness is not always funny. There are times when "tricks" of our memory can cause us great trouble.

My, what a big beak you have!

For humans, adapting to climate change will mostly be a matter of technology. More air conditioning, better-designed houses and bigger flood defenses may help to make the effects of a warmer world less harmful. {#blank#}1{#/blank#}In a paper published in Trends & Evolution, a team led by Sara Ryding, a PhD candidate at Deakin University, shows that is already. happening. Climate change is already changing the bodies of many animal species: bigger beaks (喙), limbs and ears.

In some species of Australian parrot, for instance, beak size has increased by between 4% and 10%since 1871. Another study, this time in North American dark-eyed juncos, another bird, found the same pattern.{#blank#}2{#/blank#}.

All that is perfectly consistent with evolutionary (进化) theory, "Allen's rule". Allen suggested it in 1877, holding that warm-blooded animals in hot places tend to have larger body parts than those in temperate (温带的) regions.{#blank#}3{#/blank#}Being richly filled with blood vessels (血管), and not covered by feathers, beaks make an ideal place for birds to get rid of heat.

Ms. Ryding examined museum specimens (标本) to prove that climate change was the cause of an anatomical (解剖学的) changes. All sorts of other factors might have been driving the changes. Her team combined data from different species in different places. They have little in common apart from living on a warming planet.{#blank#}4{#/blank#}.

For now, at least, the increase is small, never much more than 10%{#blank#}5{#/blank#}Since any evolutionary adaptation comes with trade-offs (妥协), it is unclear how far the process might go.

A. Therefore, climate change is the most reasonable explanation.

B. That may change as warming accelerates (加速).

C. Animals will have to rely on changing their bodies or their behaviors.

D. It seems that the future world is going to be hotter than humans are used to.

E. Therefore, the negative effects of a warmer world are visible in these animals' bodies.

F. Such adaptations boost an animal's surface area relative to its body, helping it to release extra heat.

G. Similar trends are seen in mammals, with species of mice and bats evolving bigger ears, legs and wings.
