Good news for game lovers― a tank game has come out recently. In this game you are in a tank and the screen shows your view of the landscape outside. You gain points by shooting enemy tanks, super tanks, missiles and flying saucers（飞碟）.
Expert players can gain scores of around 150,000 points at this game. To get a high score you have to destroy twenty tanks as quickly as possible. After this, the super tanks, missiles and flying saucers appear. These are worth far more points than the ordinary tanks. However, the number of tanks you have to destroy before the super tanks appear varies on different machines.
Try to get close to an enemy tank from the side or the back, so it cannot shoot at you. Then, when you get close, turn to face it, line it up in your sights and fire before it turns to shoot at you. If you miss or are too slow, quickly escape by moving out of the enemy’s line of fire. You can then move around the enemy and come in from another side.
When a super tank appears, try to destroy it as quickly as possible. Then wait safely behind an obstacle（障碍物）for a missile or flying saucer. The cubes are useful objects to hide behind as you can fire over them without exposing yourself to danger. The missiles will fly straight at you, but they are difficult to hit, so do not shoot at them until they are quite close. The saucers are much easier to hit, but do not follow them as you will be open to attack from enemy tanks. This passage is an about a game.

| C．fire straight at a missile | D．run after a flying saucer |
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.

Below is a passages adapted from a website.
| Tayka Hotel De Sal Where: Tahua, Bolivia  How much: About $95 a night Why it’s cool: You’ve stayed at hotels made of brick or wood, but salt? That’s something few can claim. Tayka Hotel de Sal is made totally of salt---including the beds (though you’ll sleep on regular mattresses (床垫) and blankets). The hotel sits on the Salar de Uyuni, a prehistoric dried-up lake that’s the world’s biggest salt flat. Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste of wet salt that hardens when it dries. When rain starts to dissolve the hotel, the owners just mix up more salt paste to strengthen the bricks. ------------------------------------------------------------------------------ ------------------------------------------------------- Green Magic Nature Resort Where: Vythiri, India  How much: About $240 a night Why it’s cool: Taking a pulley(滑轮)-operated lift 86 feet to your treetop room is just the start of your adventure. As you look out of your open window---there is no glass!---you watch monkeys and birds in the rain forest canopy(罩蓬). Later you might test your fear of heights by crossing the handmade rope bridge to the main part of the hotel, or just sit on your bamboo bed and read. You don’t even have to come down for breakfast---the hotel will send it up on the pulley-drawn “elevator”. ------------------------------------------------------------------------------ ------------------------------------------------------- Dog Bark Park Inn B&B Where: Cottonwood, Idaho  How much: $92 a night Why it’s cool: This doghouse isn’t just for the family pet. Sweet Willy is a 30-foot-tall dog with guest rooms in his belly. Climb the wooden stairs beside his hind leg to enter the door in his side．You can relax in the main bedroom, go up a few steps of the loft(阁楼）in Willy’s head, or hang out inside his nose. Although you have a full private bathroom in your quarters, there is also a toilet in the 12-foot-tall fire hydrant (消防栓）outside. ------------------------------------------------------------------------------ ------------------------------------------------------- Gamirasu Cave Hotel Where: Ayvali, Turkey  How much: Between $130 and $475 a night. Why it’s cool: This is caveman cool! Experience what it was like 5,000 years ago, when people lived in these mountain caves formed by volcanic ash. But your stay will be much more modern. Bathrooms and electricity provide what you expect from a modern hotel, and the white volcanic ash, called tufa, keeps the rooms cool, about 65℉in summer. (Don’t worry---there is heat in winter.) ------------------------------------------------------------------------------ ------------------------------------------------------- Treebones Resort Where: California, America  How much: $100 a night Why it’s cool: You can sleep in a “room” any night, but how often do you get the chance to sleep in a yurt. What’s a yurt? Good question. Yurts are the name given to guest rooms at the Treebones Resort. These spaces provide all of the accessibility to nature you’d enjoy in a tent, but with all the comforts of a cabin. In one of sixteen yurts, you will doze off(打盹儿) while gazing at the stars that can be seen through a sky dome. |

It’s nearly noon on a Saturday and you can’t believe it: your teenager is still in bed, sleeping away. But before you wake him up---mumbling to yourself that you can’t believe what a lazybones he is---you should know that he probably needs all the zzzs he can get.
As much as nine hours of sleep a night, in fact. Furthermore, teens’ circadian rhythms (i.e., processes that occur once a day) mean that young people would rather stay up past midnight and rise after 9 a.m. The result? Many teens stay up late, drag themselves out of bed early for school and try to make up the sleep debt on the weekends---or in class!
“There’s a biological reason why teens stay up late and want to sleep late,” says Dr. Stan Kutcher, the Sun Life Chair of Adolescent Mental Health at Dalhousie University in Halifax. “Their natural sleep-wake cycle changes as part of the maturation process. And because of changes in their social activities, recovering from sleep debt is more problematic.”
Teens need extra sleep for several reasons. First, their brains are changing. “The brain is reorganizing itself, laying down new pathways. What we’re seeing is a relationship between brain redevelopment and an increased need for sleep,” says Kutcher. As well, growth hormones are released during sleep, so adequate sleep is crucial for adolescents’ physical development. In addition, everything adolescents have learned in school that day is being processed and locked into long-term memory during sleep. Sufficient sleep also plays a key role in overall physical health. The immune system, for example, needs deep sleep to become and remain robust(healthy).
Staying up late on school nights means that, on average, teens get between six and a half and seven hours of sleep a night---about two hours less than they need. As a result, many either doze off in class or have trouble concentrating. Some of the behavioural problems and irritability in teens can be linked directly to sleep deprivation(损失), Kutcher says.
Then there’s the breakfast issue. Dr. Carlyle Smith, a sleep researcher and a psychology professor at Trent University in Peterborough, Ont., adds that many teens simply cannot tolerate food when they first wake up, so skipping breakfast becomes another factor in reduced alertness in class. The most obvious solution to the teen sleep problem is to have school start later in the day, but initiatives(积极性) toward this across the country have gone nowhere, Smith says, mainly because of costs and resistance from school boards and teachers.
So for now, just sympathize with your teens. Encourage them to go to bed, if not early, then at least at a regular time, so they won’t develop insomnia from erratic(不稳定的) schedules. Warn them not to have too many caffeinated drinks before bed. And don’t let sleeping away the weekend become an issue to fight over. Schedule family activities to take place later in the day on weekends and let them sleep in. “If you want your kids to grow and remember stuff, let them sleep,” says Smith. “It’s not laziness. Their brains are working really, really hard.” The word “zzzs” (Paragraph 1) most probably means __________.
| A．food | B．sleep | C．energy | D．blame |
What causes teenagers to be less sleepy late at night and more sleepy early in the morning?
| A．Caffeinated drinks. |
