A small dog should be belly-up after eating a handful M&M’s, at least according to conventional wisdom. But watching “Moose”, a friend’s five-pound Chihuahua, race around a living room after his sweet snack makes one wonder: Is chocolate truly poisonous to dogs?
Dogs and humans have similar tastes. But unlike humans, our companions experience dangerous effects from eating chocolate — it can poison them and in some cases is fatal. Chocolate’s danger to dogs depends on its quality.
Chocolate is processed from the bitter seeds of the cocoa tree, which contain a family of compounds known as methylxanthines(一种衍生物). This class of substances includes caffeine and the related chemical theobromine(可可碱). Chocolate contains a significant amount of theobromine and smaller amounts of caffeine. These chemicals can cause a dog’s heart to race up to twice its normal rate, and some dogs may run around as if “they drank a gallon of espresso,” according to Hackett.
Dogs are capable of handling some chocolate, but it depends on the animal’s weight and the type of chocolate it eats. Unsweetened baking chocolate contains more than six times as much theobromine as milk chocolate, although amounts vary between cocoa beans as well as different brands of chocolate. Less than four ounces of milk chocolate is potentially fatal for Moose and other small dogs.
Around every confection-centered holiday — Valentine’s Day, Easter and Christmas — at least three or four dogs are hospitalized overnight in the animal medical center at Colorado State. But in 16 years, Hackett has seen just one dog die from chocolate poisoning, and he suspects it may have had an underlying disease that made it more exposed to chocolate’s heart-racing effect.

Computer programmer David Jones makes 35,000 pounds a year designing new computer games, yet he cannot find a bank prepared to let him have a credit card (信用卡). Instead, he has been told to wait another two years, until he is 18.
The 16-year-old boy works for a small firm in Liverpool, where the problem of most young people of his age is finding a job. David’s firm puts two new games on the home market each month.
But David’s biggest headache is what to do with his money. In spite of his salary, made by inventing new programs within a quite short period of time, the bonus payments and profit-sharing (奖金和分红), he cannot drive a car, get some money from a bank to buy a house, or get credit cards.
He lives with his parents in their house in Liverpool, where his father is a bus driver. His firm has to pay £150 a month in taxi fares to get him the five miles to work and back every day because David cannot drive.
David got his job with the firm a year after leaving school with six 0-levels and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs,” he said.
“I suppose 35,000 pounds sounds a lot but actually that’s not good enough. I hope it will come to more than that this year.” He spends some of his money on records and clothes, and gives his mother 20 pounds a week. But most of his spare time is spent working.
“Unfortunately, computing was not part of our studies at school,” he said. “But I had been studying it in books and magazines for four years in my spare time. I know what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway.”
David added, “I would like to earn a million and I suppose early retirement (退休) is a possibility. You never know when the market might disappear.”

It is often necessary to release a fish, that is , set it free after catching, because it is too small, or you just don’t want to take it home to eat. In some cases, releasing fish is a good measure that will help keep fish variety and build their population size. The Department of Game and Inland Fisheries (DGIF) encourages fishermen who practice catch-and-release fishing to use a few simple skills when doing so. The advice provided below will help make sure that the fish you release will survive to bite again another day.
—When catching a fish, play it quickly and keep the fish in the water as much as possible.
Don’t’ use a net in landing the fish and release it quickly to prevent it from dying.
—Hold the fish gently. Do not put your fingers in its eyes. Don’t wipe the scales (鱼鳞) off the fish because it might cause it to develop a disease and reduce its chance of survival.
—Remove your hook quickly. If the hook is too deep or hooked in the stomach, cut the line and leave the hook in. The hook left inside will cause no serious problem to the fish.
—Take good care of the fish by moving it gently in water. Release the fish when it begins to struggle and is able to swim.
—Do not hold fish in a bucket or some other containers and later decide to release it. If you are going to release a fish, do so right away.
With a little care and by following the suggestions given above, you can give the released fish a better chance of survival.
