For hundreds of millions of years, turtles (海龟) have struggled out of the sea to lay their eggs on sandy beaches, long before there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to hand-carry the hatchlings (幼龟) down to the water's edge lest (for fear that) they become disoriented by headlights and crawl towards a motel parking lot instead. A formidable wall of bureaucracy has been erected to protect their prime nesting on the Atlantic coastlines. With all that attention paid to them, you'd think these creatures would at least have the gratitude not to go extinct (die out).

    But Nature is indifferent to human notions of fairness, and a report by the Fish and Wildlife Service showed a worrisome drop in the populations of several species of North Atlantic turtles, notably loggerheads, which can grow to as much as 400 pounds. The South Florida nesting population, the largest, has declined by 50% in the last decade, according to Elizabeth Griffin, a marine biologist with the environmental group Oceana. The figures prompted Oceana to petition the government to upgrade the level of protection for the North Atlantic loggerheads from "threatened" to "endangered"— meaning they are in danger of disappearing without additional help.

    Which raises the obvious question: what else do these turtles want from us, anyway? It turns out, according to Griffin, that while we have done a good job of protecting the turtles for the weeks they spend on land (as egg-laying females, as eggs and as hatchlings), we have neglected the years spend in the ocean. "The threat is from commercial fishing," says Griffin. Trawlers (which drag large nets through the water and along the ocean floor) and longline fishers (which can deploy thousands of hooks on lines that can stretch for miles) take a heavy toll on turtles.

    Of course, like every other environmental issue today, this is playing out against the background of global warming and human interference with natural ecosystems. The narrow strips of beach on which the turtles lay their eggs are being squeezed on one side by development and on the other by the threat of rising sea levels as the oceans warm. Ultimately we must get a handle on those issues as well, or a creature that outlived the dinosaurs (恐龙) will meet its end at the hands of humans, leaving our descendants to wonder how creature so ugly could have won so much affection.

How to make Quick Decisions For Your Life

    We make decisions every day{#blank#}1{#/blank#}When it comes to making decisions, choosing the right one can at times be stressful, especially if the decision must be made quickly. Indecision often weighs us down, but there are some useful tips for making quick decisions more easily.

    {#blank#}2{#/blank#}Sometimes the key to making a quick decision comes down to planning ahead of time for just such an occasion. We all know we're going to come to an important decision-making point sooner or later, so having a plan already in hand can put our mind at ease when that time comes.

    Overcome fear.{#blank#}3{#/blank#}While it may seem difficult to overcome the fear of making the wrong choice, many experts agree that we shouldn't be afraid to make the wrong decision, even if it seems important. The vast majority of wrong decisions can be corrected, while delaying decisions can often lead to more problems.

    Write down all the advantages and disadvantages of your decision. Even if you don't have all the information, writing down all the pros and cons（优缺点） is a good starting point for figuring out what to do. In cases where there simply isn't enough time to write things down, make a mental list in your mind. Thinking of the pros and cons can help you organize your thoughts.{#blank#}4{#/blank#}

    Determine criteria. Remember that every decision you make should come with a certain list of criteria.{#blank#}5{#/blank#}But once you know the requirements you're looking for, making a decision will become easier. Look for the choice that satisfies the list you've made, and once that choice is found, you should move ahead with it.

A. Have a plan.

B. The list may be short or quite long.

C. Communicate your decision with others.

D. And this can always lead to a clear answer.

E. So cut out any options that you know you will not choose.

F. Often, one thing that keeps us from making decisions is fear.

G. Some can be very important while others are not serious in the long run.

    Proper diet and regular exercise seem to be the only methods for losing weight.However,the importance of water should be added in the process.While medical science has proven the positive effects of water,most people still do not drink enough each day.

    The reason why water is so important for weight loss has something to do with metabolism（新陈代谢）of fat. The liver（肝脏）is in charge of this process when it comes to turning stored fat in-to energy.However,the liver is also responsible for helping the kidneys（肾脏）that need enough water in order to function properly.The liver has to perform all the functions of the kidneys on its own when they are short of water.This means the liver doesn't have enough energy to metabolize fat.So,drinking water allows the kidneys to focus on their job and the liver to focus on its job.

    Also,studies have shown that water can make us feel full when drunk before meals.Without even making an effort,most people who drink a glass of water before a meal will eat 33% less.This is due in part to the fact that they simply get fuller quicker because the water is taking up space.The other reason is that the food will expand as soon as it hits the water-filled stomach.

    Water is important for every aspect of the health of the human body.By drinking more water and improving the health of the body,weight loss goals can be achieved with greater ease.

Being a superhero to others

    Ewan Drum has always liked superheroes. He likes how they help people. At age seven, he told his parents, “I want to dress up like a superhero and help the homeless.” {#blank#}1{#/blank#}Wearing his red superhero cape (斗篷), Ewan helped pass out  bag lunches to hungry people in a park in Detroit, Michigan. That's how Super Ewan was born.

    {#blank#}2{#/blank#}People donated(捐赠) money and supplies (供给物), and Ewan took them to those in need.

    When someone donated jugs(大罐) of water, Ewan and his family drove their car to get even more. They took the water to Flint, Michigan, a city that had unsafe drinking water. Another time, a businessman donated six turkeys(火鸡) for Thanksgiving.{#blank#}3{#/blank#}“In the end”, he says, “we gave turkey dinners to families all around Detroit.”

    Ewan has a motto: Everyone can be a superhero to someone. At an event called the Hero Round Table, Ewan told the audience, “It's not hard to help people. You can keep some socks and food in your car to help people in need. You can help a neighbor with doing the garden. {#blank#}4{#/blank#} ”

It's been several years since Super Ewan started his task. Every month, he still visits the same park to hand out clothes, food, and supplies to people who are hungry or homeless —his Super Friends. {#blank#}5{#/blank#}

    “No matter what,” Ewan says, “I will always keep helping people.”

A. News spread about Ewan's act of kindness.

B. This superhero says he'll never take off his cape.

C. Ewan says he wants more adults to act like superheroes.

D. Every little thing helps and can make someone feel happy.

E. A few months later, Ewan's family planned a day of giving.

F. Several days later, his parents drove to Flint and helped him raise a lot of money.

G. With his parents help, Ewan asked for more turkeys through the Internet, plus side dishes.

    Sometimes it can be hard to recognize a true friend, one who is loyal (忠诚的) and one who is worth keeping by your side. The suggestions provided in this article will help to guide you in working out which friends are likely to be true.

    Be able to trust your friends. You should be able to trust true friends and they should return this trust. Your friends tell you secrets that no one else knows. Let you share secrets. Ask you for advice. {#blank#}1{#/blank#} However, if your friends hide things from you and act secretive, this could be a sign that they do not trust you, but it could also mean your friends keep to themselves or don't like to reveal too much about themselves.

    Consider comfort. How comfortable do your friends feel when they are around you? Watch them, are they being themselves or are they timid (胆怯的) around you? {#blank#}2{#/blank#} True friendships can take a while to develop, but if your friends are true, they should feel comfortable around you.

    {#blank#}3{#/blank#} This is not meant in a romantic way, but consider whether your friends are comfortable with the touch. If your friends are fine with hugging you, leaning on you, resting their heads on your shoulder and so forth, then you can judge they love you.

    Think about loyalty. True friends are always there for one another. If you are in need of a helping hand, your true friends should be there to offer it to you. {#blank#}4{#/blank#} You can trust friends with anything, knowing that they will be loyal and will not let your secrets out.

    Look at how you fight. Nearly all best friends fight; so if you and your friend have a little dispute (争论), don't sweat it! {#blank#}5{#/blank#} They will not tell each other's secrets and they still care about each other.

    Tiny microbes(微生物)are at the heart of a new agricultural technique to manage harmful greenhouse gas. Scientists have discovered how microbes can be used to turn carbon dioxide into soil-enriching limestone(石灰石), with the help of a type of tree that grows in tropical areas, such as West Africa.

    Researchers have found that when the Iroko tree is grown in dry, acidic soil and treated with a combination of natural fungi(霉菌)and other bacteria, not only does the tree grow well, it also produces the mineral limestone in the soil around its root.

    The Iroko tree makes a mineral by combining Ca from the earth with CO2 from the atmosphere. The bacteria then create the conditions under which this mineral turns into limestone. The discovery offers a new way to lock carbon into the soil, keeping it out of the atmosphere. In addition to storing carbon in the trees, leaves and in the form of limestone, the mineral in the soil makes it more suitable for agriculture.

    The discovery could lead to reforestation(重新造林)projects in tropical countries, and help reduce carbon dioxide in the atmosphere in the developing world. It has already been used in West Africa and is being tested in Bolivia, Haiti and India.

    The findings were made in a three-year project involving researchers from the Universities of Edinburgh, Granada, Lausanne and Delft University of Technology. The project examined several microbiological methods of locking CO2 as limestone, and the Iroko-bacteria way showed best results. Work was funded by the European Commission under the Future Emerging Technologies (FET) scheme.

    Dr Bryne Ngwenya of the University of Edinburgh's School of GeoSciences, who led the research, said: "By taking advantage of this natural limestone-producing process, we have a low-tech, safe, readily employed and easily operating way to lock carbon out of the atmosphere, while improving farming conditions in tropical countries?
