    Small islands that bear the brunt of rising sea levels also face the greatest risk of diseases linked to a warmer planet, health leaders said on Saturday, as 13 million medical professionals added to the calls for a global climate pact.

    Hundreds of thousands more people will die every year from heat stroke and tropical illnesses unless negotiators in Paris can agree a strong global deal to decrease global warming the Global Climate and Health Alliance said.

    The Would Health Organization has warned that the effects of extreme weather on the fight against malnutrition, malaria and diarrhea alone will account for an extra 250,000 premature deaths a year by 2030.

    “In the case of small island states like Tuvalu, the health impacts of climate change are palpable,” said the island's health minister.

    “When we are talking about climate change, this is important for the future health of our people, and people everywhere.”

    John Usamate, health minister for Fiji, said the island was suffering from climate-related diseases such as dengue fever and chikungunya, a disease transmitted by mosquitoes and unknown in Fiji.

    “As the climate changes, we are seeing new infectious diseases and many other health impacts,” he said.

    The Global Climate and Health Alliance groups more than 1,700 health organizations and 8,200 hospitals and health facilities.

    It is said it had collected 13 million signatories（签字者） from its members wanting to come to a medical agreement on the need to fight against global warming.

    Even without the wider effects of climate change, air pollution from fossil fuels, especially from coal-fired electricity and vehicle emissions（排放）, is a major cause of early death.

    In the European Union, more than 400,000 early deaths a year are linked to air pollution that cause respiratory disease and some forms of cancer, the European Commission has found.

    Flying devices called drones(无人机) may be one of the most important technologies of the future.

    The number of jobs for people who know how to design, build and control them is increasing. Because of this increase, several U.S. universities have started offering degrees in unmanned aircraft systems, or UAS.

    One of these universities is the University of Washington in Seattle. Ward Handley is seeking a master's degree in UAS at the university. When the drone program first began, he did not think it was a good idea. “Drones can be used to invade privacy(侵犯隐私).” He said. But later, Handley changed his opinion. He said, “I think there are good enough purposes for them.”

    The FAA (the part of the U.S. government that controls air travel and traffic) is creating new rules to control the use of drones, however. A new law requires drone owners to register(登记) their drones. People who do not register their drones could face fines of up to US$20,000.

    The new rules may also present problems for students. One problem is finding a legal place to fly.

    Students at Blue Mountain Community College fly inside the college gym. In Seattle, University of Washington students test their drones in a big room.

    Christopher Lum, a scientist at the University of Washington, helps students explore how drones can safely share the sky with regular aircraft. Lum explained why they test drones inside a building, “We need to register our aircraft and get permission to fly outside. That process can take months.”

    At this time, Kansas State University is the only school with permission to offer unmanned aircraft flight classes to students outside. The FAA selected Kansas State University and 15 other universities to be part of a national research group.

    Lum and some of his students recently moved their research to Australia. Australia has fewer rules limiting drones. A professor at Western Washington University also took his department's drones to Canada for the same reason.

    Mary Anning was an English fossil collector, dealer and paleontologist(古生物学家). Her fossil-hunting helped change the way people thought about the world.

    Mary was born into a poor family in England on May 21, 1799. She lived in the seaside town of Lyme Regis, in Dorset. The family had nine children. Only Mary and her brother Joseph grew up. Mary's father took his children along the beach. They picked up shells and stones to sell to visitors. Mary did not go to school much. Her family was too poor. And schools did not teach children about fossils. Mary could read and write. She taught herself. She learned about rocks and how bodies are made.

    In 1811 when Mary and Joseph were fossil hunting, Joseph saw a bone sticking out of the rock. Mary had a hammer to chip away at the rock. Very carefully she uncovered it. She found the first complete fossil of the ichthyosaur(鱼龙).

    Since then, Mary became crazy about fossil hunting. She liked to hunt on the beach after a storm. The wind, rain and waves made the rocks crumble. It was easy to spot fossils. Most days Mary went fossil hunting with her dog, Tray.

Rich friends helped Mary by selling fossils for her. They sent her money. Scientists wrote letters and came to see her. One good friend was William Buckland, a professor at Oxford University. Mary also opened a shop to sell fossils, stones and shells. She chatted with visitors.

    Mary Anning died in 1847. How evolution(进化)works was explained by Charles Darwin not long after Mary died. Her fossils had helped scientists understand how things began.

Research has shown that mindful eating has positive impacts on people, so it's beneficial to know how to eat more mindfully. Here are some techniques for eating at a healthy pace

Remove all distractions while your eat. {#blank#}1{#/blank#} Make sure your cell phone is face down and you' re not going to be responding to any messages that come through.

Take enough time to finish your meal. Even with all distractions removed, very often you still find yourself eating faster than you should.{#blank#}2{#/blank#} It takes about that time for your body to get the signal to the brain that you are full.

{#blank#}3{#/blank#}You might wonder how to spend 20 whole minutes eating a sandwich. One way to slowdown is to engage your senses and think through all the details about your meal. Ask yourself: What's on my plate? How hungry am I today? Is it too salty? Notice the smell, the taste and whatever other senses that arise as you eat.

Limit the amount of the food you might munch on(大口吃) mindlessly. Put a small amount of snack food, like potato chips, in a separate bowl to help avoid mindless munching. {#blank#}4{#/blank#} Putting aside some of the food can help you eat less at a healthier pace.

Actually chew. If you' re wolfing down(狼吞虎咽) your food you' re probably not chewing it. And chewing is an important part of digestion. {#blank#}5{#/blank#} Look at each bite before putting it into your mouth, acknowledge what you' re eating and chew, chew, chew.

A. Notice all the little details about your food.

B. Limit your time for a meal within 20 minutes.

C. It helps break up the foods so it's easier for absorption.

D. Watch out for your food intake and the time you spend on it.

E When you sit down to eat, spend at least 20 minutes doing so.

F. If you have a whole bag of it, it is challenging to stop after several bites.

G. They can limit your ability to enjoy your food and notice when you are full.
