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（一種衍生物）. This class of substances includes caffeine and the related chemical theobromine(可可堿). 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.

      an ounce of unsweetened baking chocolate is safe for Moose
    4. D.

    1. A.

    2. B.

    3. C.

An analysis by Mount Sinai researchers of over eight years of dietary data from more than 400,000 people has found that the relationship between high consumption of fruits and vegetables and a reduced risk of cancer is not as strong as commonly thought. The study is published online April 6, 2010 in the Journal of the National Cancer Institute. It is widely believed that a diet rich in fruits and vegetables can reduce the risk of cancer. In 1990, the WHO recommended eating five servings of fruits and vegetables a day to prevent cancer and other diseases. However, although many studies have been conducted since then, none have been able to confirm an association between fruit and vegetable intake and cancer resistance.
Paolo Boffetta, MD, MPH, lead author of the study and Deputy Director of The Tisch Cancer Institute at Mount Sinai School of Medicine, and colleagues analyzed data from the EPIC study to evaluate relationships between cancer risk and intake of total fruit and vegetables combined.
The EPIC followers, which are ongoing and organized by professor Elio Riboli at Imperial College in London, included 142,605 men and 335,873 women surveyed between 1992 and 2000 from 10 Western European countries. Detailed information on their dietary habits and lifestyle differences was obtained. After 8.7 years of follow – up, more than 30,000 of the study's participants were diagnosed with cancer.
Dr. Boffetta and colleagues found a small but significant opposite relationship between high intake of fruits and vegetables and overall cancer risk. In this population, an increase of 200 grams a day of fruits and vegetables resulted in a reduction of about 3 percent of cancer risk. Vegetable consumption by itself also afforded a modest benefit but was restricted to women. Heavy drinkers who ate many fruits and vegetables had a somewhat reduced risk, but only for cancers caused by smoking and alcohol.
"The bottom line here is that, yes, we did find a protective effect of fruit and vegetable intake against cancer, but it is a smaller connection than previously thought," said Dr. Boffetta. "Any cancer protective effect of these foods is likely to be modest, at best.
"However, eating fruits and vegetables is beneficial for health in general and the results of this study do not justify changing current recommendations aiming at increasing intake of these foods," said Dr. Boffetta.
63．A new study shows that         .
A．eating fruits and vegetables is beneficial to health
B．a(chǎn) diet rich in fruits and vegetables can reduce the risk of cancer
C．eating five servings of fruits and vegetables a day can prevent cancer and other diseases
D．the association between fruit and vegetable intake and cancer resistance is small
64．Before this study, people would believe that        .
A．high intake of fruits and vegetables can prevent cancer and other diseases
B．heavy drinkers have the slightest chance of cancer
C．the WHO’s recommendations were modest
D．the WHO’s recommendations aim at increasing intake of fruits and vegetables
65．The population who took part in this study amounted to       .
A．142,605    B．335,873    C．more than 400,000   D．30,000
66．From this study, we can infer that         .
A．the intake of fruits and vegetables will be no longer necessary
B．the connection between fruits and vegetables intakes and cancer resistance is smaller than originally thought
C．taking in fruits and vegetables will still be appreciated in spite of the new discovery
D．a(chǎn)ny cancer protective effect of these foods is likely to be modest

(E)
Everybody has to buy or sell things sometimes. Even students, who are usually not very rich, have to learn something about making purchases(買東西) intelligently. As a student you may find, for example that you need to buy a walkman or winter clothing. You may want to buy a television or a used car. Of course, you want to get good value for your money. If you are considering a major purchase, or any purchase, you should remember several important things.
◎Study first, and then decide what you want to buy. You can learn a lot just by reading books and advertisements.
Remember that a high quality product will probably last longer and work better. Of course,
for a superior(優(yōu)良的) product you are expected to pay more. An inferior product may not give you the same quality, but the price should be low. Perhaps this seems obvious, but you know the quality. Don’t just look at the price. A poor quality product could be expensive. And a valuable one could be on sale at a greatly reduced price.
◎Don’t hurry. Take your time. After you decide what product you want, go to many different stores. If you cannot find the product you want, you may try to order it directly form the factory or ask the store to order it for you.
Look for a good deal. If you wait, you will probably find that your product will go on sale and
you may be able to save 10,20,or even 50 percent of the original price.
◎Finally, before you buy, make sure that the product is guaranteed(質量保證). If you find the lowest possible price, you will generally be happy with your purchase and also keep more money in the bank.
73. What’s the best title for this passage?
A. What products are of high quality   B. Do shopping wisely as a student
C. How to save your money          D. Take your time when shopping

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 (獎金和分紅), 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.”
【小題1】Why is David different from other young people of his age?

A．He earns a very high salary.B．He has not a job.
C．He does not go out much.D．He lives at home with his parents.
【小題2】David’s greatest problem is ____________.
A．making the banks treat him as a grown-up B．inventing computer games
C．spending his salaryD．learning to drive
【小題3】He was hired by the firm because ____________.
A．he had worked in a computer shopB．he had written some computer programs
C．he worked very hardD． he had learned to use computers at school
【小題4】He left school after taking six 0-levels because ____________.
A．he did not enjoy school
B．he wanted to work with computers and staying at school did not help him
C．he was afraid of getting too old to start computing
D．he wanted to earn a lot of money
【小題5】Why does David think he might retire early?
A．One has to be young to write computer programs.
B．He wants to stop working when he is a millionaire.
C．He thinks computer games might not always sell so well.
D．He thinks his firm might go bad.

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 (魚鱗) 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.
