A rising population is one of the main reasons that there is global warming. Between 1650 and 1850 the population increased by 0.75 billion people going from 0.25 billion to one billion. From 1930 to the end of the century the population rose from two billion to over six billion. In just a third of the time the population rose by more than five times what it did before. It is expected that this trend in the changing population will continue and could even heighten. The growing population requires increasing amounts of energy. These energy demands and other supplies require production, which almost always involves the emission of greenhouse gases. The more the population increases the more greenhouse gases that are produced and the greater the increase in temperature.

    The burning of fossil fuels is one of the best-known causes for global warming. The major reason for fossil fuels contributing so much to global warming is the release of carbon that occurs during the burning of fossil fuels. When people burn fossil fuels, they release large amounts of carbon by way of the release of carbon dioxide. The carbon dioxide in the air then leads to global warming.

    Another source of carbon dioxide comes from deforestation. In forests there is a large amount of carbon that is stored in the trees and other plants. This carbon is out of the atmosphere because the trees consume the carbon from carbon dioxide. When people cut down trees, they are frequently burned. This burning releases the carbon dioxide into the atmosphere that was stored in organic matter. Even when new trees are planted, it can take up to one hundred years to make up for the carbon that was released. It is commonly thought that because trees absorb more carbon dioxide, the atmosphere experiences positive effects.

    Sophie Armstrong, the writer of Earth Care put it, “There's no doubt that the earth is becoming warmer because of human activity rather than a random but natural phenomenon.

    Today's museums include plenty of high culture, but you can still find shrines（圣地）to the extraordinary. Here's a look at five curious museum stops across Canada.

Vancouver Police Museum

    The setting, terrible enough, is the old Coroner's（验尸官）Court and forensics lab, including the morgue(room where dead bodies are kept). Artifacts, from the 1870s on, include badges, uniforms, police equipment, items from criminals, and even preserved organs—all in all an arresting experience.

Vulcan Tourism & Trek Station

    Designed to resemble a spacecraft, the Treck Station celebrates Vulcan's coincidental relationship to Mr. Spock's planet, Go to a building that features an 800-piece collection of Star Trek memorabilia — including Spock's ears and floor-to-ceiling space paintings.

Accordion（手风琴）Museum

    Through instruments, photos and recordings, the museum traces the history of the accordion and its influence on Quebec culture. They've even acquired Asian instruments that show the use of the free reed— call them ancient ancestors of the accordion—that date back 4000 years.

Chocolate Museum

    It's chocoholic heaven — whole museum featuring displays on how chocolate is made, hands-on exhibits, collections of historic chocolate boxes, and antique candy- making equipment and, of course, lots of chocolate treats ,located in an old candy factory building.

Potato museum

    A 14--foot high potato greets you at what's billed as the world's largest exhibit of potato artifacts. Explore the humble potato's role in the economy, a collection of farm tools related to growing and harvesting potatoes, Hall of Fame.

    “Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour ( also called free running－a kind of extreme sport).

    Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has become popular worldwide.

    Yes, that's parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.

    Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.Overcoming all the obstacles on the course and in life is part of the philosophy(理念) behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life, to reach the destination successfully. A parkour lover said, “I love parkour because its philosophy has become my life, my way to do everything.”

    Another philosophy we've learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself that you earn energy and confidence.

    Watching some children trying to catch butterflies one hot August afternoon, I was reminded of an incident in my own childhood．When I was a boy of 12 in South Carolina, something happened to me that cured me forever of wanting to put any wild creature in a cage.

    We lived on the edge of a wood, and every evening at dusk the mockingbirds would come and rest in the trees and sing. There isn't a musical instrument made by man that can produce a more beautiful sound than the song of the mockingbird.

    I decided that I would catch a young bird and keep it in a cage and in that way would have my own private musician.

    I finally succeeded in catching one and put it in a cage. At first, in its fright at being captured, the bird fluttered about the cage, but eventually it settled down in its new home. I felt very pleased with myself and looked forward to some beautiful singing from my tiny musician.

    I had left the cage out on our back porch, and on the second day of the bird's captivity my new pet's mother flew to the cage with food in her mouth. The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby.

    The following morning when I went to see how my captive（被俘虏的） was doing, I discovered it on the floor of the cage, dead. I was shocked! What had happened! I had taken excellent care of my little bird, or so I thought.

    Arthur Wayne, the famous ornithologist, happened to be visiting my father at the time, hearing me crying over the death of my bird, explained what had occurred. “A mother mockingbird, finding her young in a cage, will sometimes bring it poison berries. She thinks it better for her young to die than to live in captivity.”

    Never since then have I caught any living creature and put it in a cage. All living creatures have a right to live free.

    A 16-year-old in foster care has finally found a home. His adoption caseworker (社会工作者), who has known him since he was 7, will become his adoptive mother this month.

    In October 2013, Davion Only spoke in front of a church congregation (会众) in St. Petersburg, Florida, and made an 1 for adoption. He had recently learned that his 2  mother, who'd been in jail since Only was born, had died. He had spent years bouncing between foster homes. “My name is Davion and I've been in foster care since I was born,” he said. “I know God hasn't given up on me, so I'm not giving up either.”

    The 3  plea (恳求) went viral, and Only's foster agency 4  calls from more than 10,000 people, according to the Tampa Bay Times. Only  5  traveling to Ohio to live with a minister's family. But after Only got into a physical  6  with one of his older would-be siblings (兄弟姐妹), the minister and his wife changed their minds.

    Back in Florida, Only passed through four different  7  homes over the next year, until he called Connie Going, his adoption caseworker, to make a special  8 .

    Only had known Going for nearly ten years, and had asked every year if she would adopt him but she always  9 . “I always believed there was a better family than us out there,” Going tells Yahoo Parenting. “He  10  so much in this world.”

    But this past July, when Only called and asked again if she might adopt him, Going says something felt  11 . “In adoption there is a ‘claiming moment,' when you know someone is your child. When he called me to ask, in that moment, I just knew,” she says. “When he asked me, my heart felt this  12  and I just knew he was my son.”

    So Going, 52, invited Only to start spending time  13  the rest of her family — the other four children who she also adopted out of foster care.  14 , Going managed to rent a bigger home, got a lawyer, and started adoption  15  .

    Only will officially join Going's family on April 22, when the adoption  16 . “Today, I am feeling blessed and honored by being chosen to be the parent to all my children,” she says. “I work every day on being the best parent I can to them, to be patient and creative so that I can  17  all their needs.”

    A spokesperson for Eckerd, Only's foster agency, told the Tampa Bay Times they were 18  with the new development. “We are truly thrilled that Davion has been united with his forever family.“

    While Going is waiting for the newest  19  to her family to become official in the eyes of the law, she says Only is already her child. “I want him to know he is  20  loved for who he is, the way he is,” she says. “The changes he chooses to make in his life, and the choices, are his to make. As a family we will be there through it all, the good and the bad for our lifetime. He is home.”

    Save Your Time, Money and Stress with Savvy (懂行，悟性）Rental Car Strategies

    Renting a car can be expensive, confusing, and stressful — but it doesn't have to be. Here are several helpful strategies to save money, time, and stress on your next (and every) car rental.

Sign Up for Loyalty Programs

    Rental car loyalty programs are free to join, so register for any programs you might use in the future. My favorite car rental loyalty program benefit is that I can skip the counter and head right to my reserved car. Some programs allow members to choose a car from the available pool.       

Optimize Your Strategy

    Do you really need a rental car from the airport? For instance, if your flight arrives at night, take a free hotel shuttle and pick up your car the next day. The car rental location might even be at your hotel or can pick you up (or deliver the car to you).      

    For a city trip, you may not even need a rental car. Research whether mass transit（运输）, taxi, Uber, bike rental, and other transportation methods will suffice(足够）. Parking charges at downtown hotels may cost more than your car rental rate, so it may be doubly in your favor to give up a rental car. In some locations, a bike might be more efficient and economical than a car.

 Search for Specials

           In conjunction（结合）with your personal discount code, you may also find a last-minute rate, free rental day, or other promotion. My favorite annual travel deal is driving a car one-way out of Florida after Spring Break with rates as low as $1 per day.

Consider Alternative Rental Options

    Major car rental companies might have an associated discount brand at your rental location, like Firefly for Hertz.       

    An independent or smaller local agency may fit your needs; like A1 or Lucky Owl in Honolulu. Many people prefer to check rates on Hotwire and Priceline, especially for last-minute rentals.

A．Rental rates are likely lower away from the airport, plus you might save the cost of an entire rental day.

B．I use discount-finding websites to track my car reservations.

C．Smaller brands, like Thrifty and Fox, might offer better service and lower rates.

D．In addition to saving time and offering freedom of choice, loyalty members earn points and receive special promotions.

E．Check car rental company websites for current specials.

F．Skip the Car

G．Use a bike

preface.序言

    This passage mainly tells us the       (valuable) of a person. A collage student in this passage        (choose)the wrong major and became more and more frustrated.

    It was 6 pm when we arrived Belfast, so we went straight to the hotel that we booked online to check in after we got on the plane. On our way to the downtown, the taxi driver brief introduced the city, which had been in chaos for almost 30 years until the end of next century. After dropped our bags, we wandered around in the streets. The city was peacefully and people seemed to be enjoying their life very much. The place that we had our dinner was called “The Crown”, a pub dated back to 1826, when the first train ran from Belfast to Lisburn. We met two European girls having Chow Mein, fried noodles, when we were having a rest in the hall of the hotel later. They told us they have bought the noodles in a Chinese restaurant named Eastern Land. We decided not to go there the next evening so that we could taste it.
