WASHINGTON---Think you’re savvy about food safety? That you wash your hands well, scrub away germs, cook your meat properly?
Guess again.
Scientists put cameras in the kitchens of 100 families in Logan, Utah. What was caught on tape in this middle-class, well-educated college town suggests why food poisoning hits so many Americans.
People skipped soap when hand-washing. Used the same towel to wipe up raw meat juice as to dry their hands. Made a salad without washing the lettuce. Undercooked the meat loaf. One even tasted the marinade in which bacteria-ridden raw fish had soaked.
Not to mention the mom who handled raw chicken and then fixed her infant a bottle without washing her hands.
Or another mom who merely rinsed(冲洗) her baby’s juice bottle after it fell into raw eggs---no soap against the salmonella(沙门氏菌) that can lurk(潜伏) in eggs.
“Shocking,” was Utah State University nutritionist Janet Anderson’s reaction.
Specialists call this typical of the average U.S. household: Everybody commits at least some safety sins(罪恶) when they are hurried, distracted by fussy children or ringing phones, simply not thinking about germs. Even Anderson made changes in her kitchen after watching the tapes.
The Food and Drug Administration funded Anderson’s $50,000 study to detect how cooks slip up. The goal is to improve consumers’ knowledge of how to protect themselves from the food poisoning that strikes 76 million Americans each year.
“One of the great barriers in getting people to change is they think they’re doing such a good job already,” said FDA consumer research chief Alan Levy.
Surveys show most Americans blame restaurants for food-borne illnesses. Asked if they follow basic bacteria-fighting tips---listed on the Internet at www.fightbac.org---most insist they’re careful in their kitchens.
Levy says most food poisonings probably occur at home. The videotapes suggest why. People have no idea that they’re messing up, Anderson said. “You just go in the kitchen, and it’s something you don’t think about.”
She described preliminary(初步的) study results at a food meeting last week. Having promised the families anonymity, she didn’t show the tapes.
For $50 and free groceries, families agreed to be filmed. Their kitchens looked clean and presumably(perhaps) they were on their best behavior, but they didn’t know it was a safety study. Hoping to see real-life hygiene, scientists called the experiment “market research” on how people cooked a special recipe.
Scientists bought ingredients for a salad plus either Mexican meat loaf, marinaded halibut or herb-breaded chicken breasts with mustard sauce---recipes designed to catch safety slip-ups.
Cameras started rolling as the cooks put away the groceries.
There was mistake No. 1: Only a quarter stored raw meat and seafood on the refrigerator’s bottom shelf so other foods don’t get contaminated(污染) by dripping juices.
Mistake No. 2: Before starting to cook, only 45 percent washed their hands. Of those, 16 percent didn’t use soap. You’re supposed to wash hands often while cooking, especially after handling raw meat. But on average, each cook skipped seven times that Anderson said they should have washed. Only a third consistently used soap---many just rinsed and wiped their hands on a dish towel. That dish towel became Anderson’s nightmare. Using paper towels to clean up raw meat juice is safest. But dozens wiped the countertop(台面板) with that cloth dish towel---further spreading germs the next time they dried their hands.
Thirty percent didn’t wash the lettuce; others placed salad ingredients on meat-contaminated counters.
Scientists checked the finished meal with thermometers, and Anderson found “alarming” results: 35 percent who made the meat loaf undercooked it, 42 percent undercooked the chicken and 17 percent undercooked the fish.
Must you use a thermometer? Anderson says just because the meat isn’t pink doesn’t always mean it got hot enough to kill bacteria.
Anderson’s study found gaps in food-safety campaigns. FDA’s “Fight Bac” antibacterial program doesn’t stress washing vegetables. Levy calls those dirty dish towels troubling; expect more advice stressing paper towels.
Anderson’s main message: “If people would simply wash their hands and clean food surfaces after handling raw meat, so many of the errors would be taken care of.”

Alzheimer’s disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer’s disease. It is a leading cause of death among the elderly. But Alzheimer’s disease is not confined （限于） to the aged. There may be a million or more people under the age of 65 suffering from the disease.
At one time, people suffering from the disease were said to be “getting old”. The disease was thought to be a natural part of growing old, but it is now known that Alzheimer’s disease strikes young and old alike. It is an organic （器官的） disease that destroys brain cells.
Alzheimer’s disease affects the patient’s memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking, then the patient’s memory begins to fail. He may forget dates, numbers, names and plans.
As the disease progresses, the patient may not recognize family and friends. These symptoms（症状） often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.
In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.
Scientists don’t know exactly what causes Alzheimer’s disease. It may be caused by a virus （病毒）.It may be caused by a poisonous substance（物质） in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.
【小题1】The main idea of the passage is that Alzheimer’s disease ________.
| A．is a terrible part of the aging process |
| B．is an organic disease that affects young and old |
| C．can be cured by physical treatment |
| D．causes forgetfulness |
| A．forgetfulness | B．difficulty in speaking |
| C．loss of sight | D．loss of the ability to walk |
| A．Poisons produced by the brain. | B．Getting old. |
| C．A virus. | D．Lack of exercise. |
| A．operation | B．a change in environment |
| C．medicines | D．physical treatment and exercise |

The Danish capital is a year-round destination. Here are some of the city's best annual events.
Roskilde Festival (July)
The Danes love the outdoors and they love rock music; the Roskilde Festival is where they combine these passions for a weekend of drunken celebration. The four-day event is held about 30 minutes from the city completely, which means you can either go in for the full festival experience, or you can travel from the city to the festival each day.
There are also day tickets if you don't have the power for the whole collection of facts.
Kulturnatten (October)
For something a little more high brow there's the Night of Culture. For one night only some 300 venues in the city stage theater performances, art exhibitions, concerts and poetry readings.
Father Christmas Congress (July)
One of the more bizarre fixtures in Copenhagen's calendar, the event is held in July—the slow season for Santas—at the Bakken amusement park, some 20 minutes north of the city. The most interesting of the event is a procession of Santas from all over the world along Str??get. Parents should be prepared for some embarrassed questions from the kids.
Tivoli Gardens (November/December)
These pleasure gardens make for a great day out any time of the year but to see them at their most attractive, visit from mid-November through December, when they are transformed into a fairy tale of lanterns and Christmas markets. There's also outdoor skating, a Christmas entertainment and the very Danish 'Nissek??bing' village, home to more than 100 mechanical fairies.
If you are free in October, you can go to _____.
A. Roskilde Festival B. Kulturnatten
C. Father Christmas Congress D. Tivoli Gardens
Roskilde Festival is a festival _____.
A. where many famous singers in Denmark gather
B. which is only held in the center of a city
C. that lasts about half an hour per day
D. that the Danas can enjoy

The passage is probably written for _____.
A. guides B. tourists C. businessmen D. writers
We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. The Sun is the major source of energy for our planet. It causes the evaporation (蒸发) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms(生物) on the Earth.
Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere,30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.
【小题1】According to the passage, the root( 根本的) cause for weather changes on the Earth is .
| A．the atmosphere surrounding the Earth |
| B．water from oceans and lakes |
| C．energy from the Sun |
| D．greenhouse gases in the sky |
| A．absorbed by the clouds in the lower atmosphere |
| B．reflected by the gases in the upper atmosphere |
| C．lost in the upper and lower atmosphere |
| D．used to evaporate water from the oceans and lakes |
| A．all living things on the Earth depend on the Sun for their food |
| B．a forest looks dark in winter because it absorbs solar energy |
| C．only 0.023% of the energy from the Sun is made use of on the Earth |
| D．greenhouse gases allow heat energy to escape from the Earth’s surface |
