An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving.In the United States,the legal blood alcohol limit is 0.08% for people aged 21 years or older,while people under 21 are not allowed to drive a car with any level of alcohol in their body.A “positive” test result,a result over the legal limit,allows the police to arrest the driver.However,many people who tested positive on the test have claimed that they only drank a “nonalcoholic” energy drink.Can one of these energy drinks really cause someone to test positive on an ABT?Researchers in Missouri set up an experiment to find out.
First,the amount of alcohol in 27 different popular energy drinks was measured.All but one had an alcohol level greater than 0.005%.In nine of the 27 drinks,the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT.They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
For 11 of the 27 energy drinks,the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken.However,alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed.This shows that when the test is taken plays an important role in the test result.The sooner the test is conducted after the consumption of these drinks,the more likely a positive alcohol reading will be obtained.

We often hear the phrase: "You've a greater chance of being struck by lightning." It is used to describe something that hasn't got much chance of happening. However, the common saying undermines(掩盖) the very real dangers of lightning.
Last Friday, at least 5 people were killed by lightning in Nepal(尼泊尔).
Lightning strikes are the second most common cause of deaths during natural disasters in the US. The first is floods. Around 400 people nationwide are struck by lightning each year, and of those, 73 people die. There are more people killed by lightning than by tornadoes and hurricanes.
Because lightning kills only one or two people at a time, its danger does not receive as much attention as other disasters.
So to raise awareness, the US has made June 22-28 National Lightning Safety Week. It aims to warn the public of the dangers of lightning and provide safety tips during thunderstorms.
"If you hear thunder, you are in danger of lightning," said Rocky Lopes, a disaster educator at the American Red Cross.
"Thunder means that lightning is close enough to hit you at any minute, so you should move indoors immediately and stay there until after the storm has ended. The single most important thing to remember is to seek a hiding place," Lopes said.
Summer is the high time for lightning storms, so when lightning strikes across the sky, remember these safety tips:
Stop working, fishing, swimming or playing in open fields.
If you can count less than ten seconds between a thunder and a lightning flash, take cover inside the nearest building.
Do not stand under a tree.
Get off bicycles or motorcycles.
Crouch down(蹲下)if there is no hiding place.
Avoid open spaces, wire fences, metal objects and electrical objects such as hair driers.
1. The popular opinion about being struck by lightening is that ______.
A. there’s a greater chance for being killed by lightening than any other natural disaster
B. it is the most dangerous among all the natural disasters
C. the chance for a person to be struck by lightening is very small
D. it is impossible for people to be killed by lightening
2.The average death rate of being struck by lightening in US is about _______.
A.18% B.50% C. 30% D. 73%
3.thunder in the open air______.
A. just stand by your bicycles and motorcycles
B. quickly find a place to go inside
C. count ten seconds between a thunder and a lightening
D. don’t have a hair drier in your hand
4.According to the passage, which of the following is TRUE?
A. There are more people killed by tornadoes and hurricanes than by lightening in US each year.
B. There are on average 5 persons killed by lightening in Nepal each day.
C. The death rate of being stuck by lightening is much higher than by other natural disasters.
D. The National Lightening Safety Week is made to warn the public against the lightening.

Eddie’s father used to say he’d spent so many years by the ocean, breathing seawater. Now, away from that ocean, in the hospital bed, his body began to look like a beached fish. His condition went from fair to stable and from stable to serious. Friends went from saying, “He’ll be home in a day,” to “He’ll be home in a week ” In his father’s absence, Eddie helped out at the pier(码头), working evenings after his taxi job.
When Eddie was a teenager, if he ever complained or seemed bored with the pier, his father would shout, “What ? This isn’t good enough for you?” And later, when he’d suggested Eddie take a job there after high school, Eddie almost laughed, and his father again said, “What? This isn’t good enough for you?” And before Eddie went to war, when he’d talked of marrying Marguerite and becoming an engineer, his father said, “What? This isn’t good enough for you?”
And now, regardless of all that, here he was, at the pier, doing his father’s labor.
Parents rarely let go of their children, so children let go of them. They move on. They move away. It is not until much later, as the heart weakens, that children understand their stories, and all their accomplishments sit on top of the stories of their mothers and fathers, stones upon stones, beneath the waters of their lives.
Finally, one night, at his mother’s urging, Eddie visited the hospital. He entered the room slowly. His father, who for years had refused to speak to Eddie, now lacked the strength to even try.
“Don’t sweat it, kid,” the other workers told him. “Your old man will pull through. He’s the toughest man we’ve ever seen.”
When the news came that his father had died, Eddie felt the emptiest kind of anger, the kind that circles in its cage.
In the weeks that followed, Eddie’s mother lived in a confused state. She spoke to her husband as if he were still there. She yelled at him to turn down the radio. She cooked enough food for two. One night, when Eddie offered to help with the dishes, she said. “Your father will put them away.” Eddie put a hand on her shoulder. “Ma,” he said, softly, “Dad’s gone.”
“Gone where?”

Astronauts aboard the International Space Station (ISS) recently tested an oven they used to bake five chocolate chip cookies. We now know the results of that experiment: the cookies took a lot longer to bake in space than on Earth. The cookies that came out best required two hours of baking time inside the International Space Station. The baking time for cookies on Earth is generally only about 20 minutes.
The cookies returned to Earth earlier this month aboard a SpaceX-built spacecraft that splashed down in the Pacific Ocean. The cookies are the first food baked in space from raw food materials. They remain frozen in a laboratory in Houston, Texas. The American company Nanoracks designed and built the cookie oven. Hilton DoubleTree hotels supplied the cookie dough.
The makers of the oven did expect some difference in the baking time in space, but they were surprised that that difference was so large. "There's still a lot to look into to figure out really what's driving that difference, but definitely a cool result," said Mary Murphy. She is with the company Nanoracks, which is based in Texas. Murphy said the baking results will continue to be examined in order to better understand why space baking took so much longer. In addition, researchers will study the effectiveness of the baking tray, which was designed to work in microgravity conditions.
The five chocolate chip cookies were frozen when they were sent to space. Each had to be baked separately in the oven. Italian astronaut Luca Parmitano took charge of the baking experiment in December. He reported that the first cookie stayed in the oven for 25 minutes at 149 degrees Celsius. When it came out of the oven, it was seriously under-baked. For the next two cookies, Parmitano more than doubled the baking time. Those cookies came out better, but were still under-baked. The fourth cookie stayed in the oven for two hours, after which Parmitano was able to report success. "I can't tell you whether it's cooked all the way or not, but it certainly doesn't look like cookie dough anymore," he reported to controllers back on Earth. For the fifth cookie, Parmitano turned the oven temperature up to 163 degrees Celsius and baked it for 130 minutes. This time, he reported the best baking results.
No one has tasted the space-traveling cookies just yet. Organizers of the experiment say additional testing will need be carried out to determine whether they are safe to eat.
1.How long do it takes to bake cookies in ISS?
A.About 20 minutes. B.25 minutes.
C.About an hour. D.2 hours.
2.What is the oven maker's attitude towards the large difference?
A.Critical. B.Amazed.
C.Indifferent D.Worried
3.What can we infer from the fourth paragraph?
A.The baking experiments ended up in a success.
B.Each of the five cookies was cooked in different time.
C.The more time, the better baking results.
D.The five cookies were frozen after baking.
4.What can be concluded in the passage?
A.The space-traveling cookies are safe for astronauts to eat.
B.Cookies on Earth are the same as the space-traveling cookies.
C.More tests will be taken for the space-traveling cookies.
D.The five cookies ended up in the Pacific Ocean.

Some kids start to drink alcohol (酒精) at a young age. They think it is part of becoming an adult.They also think drinking is not that bad because so many people do it.They feel it is not as bad as taking drugs (毒品). It is easy for kids to get liquor(酒精饮料)by using fake identification (伪造证件).

Kids who drink sometimes stop doing things they normally liked to do.They may keep telephone calls and meetings a secret and not want anybody to touch their things.They act moody(喜怒无常) and do not have the same eating and sleeping habits.
Parents need to stay involved (牵涉) in their kids’ lives. They should talk to their children about their problems to be aware of any changes.

“If you don’t behave,I’ll call the police” is a lie that parents generally use to get their young children to behave. Parents’ lies work in the short terns,but a new study led by NTU Singapore suggests that they’re associated with harmful effects when the child becomes an adult.
The research team asked 379 Singaporean young adults whether their parents lied to them when they were children,how much they lie to their parents now,and how well they adjust to adulthood challenges. Adults who reported being lied to more as children were more likely to report deceiving their parents in their adulthood. They also said they faced greater difficulty in meeting psychological and social challenges.
Lead author Assistant Professor Setoh Peipei from NTU Singapore’s School of Social Sciences said,“Parenting by lying can seem to save time especially when the real reasons behind why parents want children to do something is complicated to explain. When parents tell children that ‘honesty is the best policy’, but display dishonesty by lying, such behaviour can send conflicting messages to their children. Parents’ dishonesty may eventually break trust and promote dishonesty in children. Our research suggests that parenting by lying is a practice that has bad consequences for children when they grow up. Parents should be aware of this and consider alternatives to lying, such as acknowledging children’s feelings, giving information so children know what to expect, offering choices and problem-solving together, to help children develop good behaviour.”
The analysis found that parenting by lying could place children at a greater risk of developing problems that the society disapproves, such as aggression and rule-breaking behaviour. Some limitations of the study include relying on what young adults report about their past experience of parents’ lying. “Future research can explore using more information providers, such as parents, to report on the same topic,” suggested Asst Prof Setoh.
1.Why is a parental lie mentioned in the first paragraph?
A.To introduce the topic for discussion.
B.To tell a popular way to educate children.
C.To prove the great influence of the police.
D.To show the harmful effects of parental lies.
2.The underlined word “deceiving” in paragraph 2 is closest in meaning to “________”.
A.worrying B.abusing
C.disappointing D.cheating
3.According to the research,which of the following can parents do?
A.Give children chances to choose. B.Force good behaviour on children.
C.Let children solve problems alone. D.Stop children knowing what to expect.
4.What does the last paragraph imply about the study?
A.It is quite controversial. B.It is rather meaningless.
C.It needs to be perfected. D.It demands honest responses.
