(2013·济南3月模拟)—I failed my driving test.
—________；they say the best drivers always fail the first time.
A．Never mind B．Go ahead
C．No problem D．All right
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.

I grew up with a fat dad—450 pounds at his heaviest.Every week he would try a new diet，and my family ended up eating whatever strange food he was trying at that moment.
After my thirdgrade year，my dad landed a lifechanging job in Manhattan.My mom，my little sister and I had to move away from our hometown，Chicago，and leave my grandmother and her beautiful food behind.
Leaving my grandmother was far more frightening than the move to New York City.There would be no more special weekends at my grandmother’s house，the only place I can remember feeling happy，safe and nourished (有营养的)．It was what I desired.In this new city，I felt extremely alone and lost，and I missed my grandmother terribly.
My grandmother knew just how I felt—And she knew the cure.Every week，she would send me a card with a $20 bill，a recipe and a list of what to buy at the market.It kept us bonded，and her recipes filled my body and soul.
Over the years，I have grown to better understand my father’s struggles with weight and the toll (代价) it took on him and those who love him.I have come to realize he was driven not by vanity (自负) or selfishness as much as by a deep pain.And in spite of growing up in such an unhealthy eating environment (or perhaps because of it)，as an adult I found a passion and a career as a nutrition consultant.
Today，my father weighs 220 pounds and is a vegan (素食者)．How he got there is a story I hope to share in the coming weeks.More importantly，food is no longer a barrier that keeps us apart，but a bridge that keep us connected.There is nothing my dad enjoys more than talking with me about dietary theories and his weightloss victories.And now I am the one regularly sending recipe cards to my father’s house，just as my grandmother did for me.
