Many parents often say their teenage son looks like a grown man.He is taller than his father,and his voice has turned deep.But his behavior is another matter.He makes hurried decisions, tries to smoke and drink,drives cars too fast and always makes his parents annoyed.Why?

That's because his brain is developing more slowly than his body.Researchers at the National Institute of Mental Health and UCLA carried out a long?time study of normal brain development.They found that the frontal lobe (大脑额叶 ),the area responsible for understanding future influences,making wise decisions and controlling impulses(冲动),does not become mature (成熟的)until the early 20s.

Because of the immature brains,teenagers are easily influenced by the environment and unexpected behavior.So their death rates rise sharply.Research shows that rates of death by injury for people between the age of 15 and 19 are six times those seen in kids aged 10 to 14.The government reports that teens are four times more likely than older drivers to be involved in a car accident and three times more likely to die in one.

Teens may be attracted to drugs and alcohol.Rates of drug and alcohol use are high when compared with those of other age groups.Frances Jensen and David Urion,doctors at Children's Hospital Boston and Harvard Medical School,discovered that adult brain cells recovered (恢复 ) more quickly from alcohol influence than younger brain cells.Jensen said in Harvard Magazine: “For a teenager,what he drank on the weekend is still with him during that test on Thursday.”

Teens aren't making trouble on purpose.They long for freedom,but they are still young.They're still forming into the adults they'll eventually be.And,of course,they won't be at this age forever.Home education plays one of the most important roles in young people's growth,and the influence is most lasting.Finally,they will grow up and become wise adults.

A. Driving cars too fast.

B. Making their parents annoyed.

C. Quarreling with their friends.

D. Making careless decisions.

2.Teens death rates rise sharply because of their ________.

A. teenagers should have freedom to do what they like to do

B. teenagers still require lots of care and attention from their parents

C. teenagers usually make their parents annoyed on purpose

D. teenagers actually know how to make wise decisions

Got big plans for Friday night? That’s OK, we don’t either.

Guess we’ll all have to make do by watching the celestial (天空的)show that will take place that night.

First, there will be a full moon. That’s always fun, but this one will be a little more special. It’s known as a “snow moon.” The name comes from the fact that the heaviest snows usually fall during February, according to the Old Farmer’s Almanac.

But if that’s not special enough, there’s also an eclipse (月食)that night. It’ll be a penumbral lunar eclipse, meaning ifs a partial eclipse that leaves sections of the moon darkened by the earth’s shadow. No, it won’t be as spectacular as those “blood moon” eclipses. It’ll be subtler. The level of darkness it reached during the eclipse may or may not be apparent; it just depends on where you are when you view it.

In North America, the eclipse begins at 5:34 p.m. ET and ends at 9:53 p.m. ET, according to astronomy website EarthSky. The eclipse will be at its height around 7:44 p.m. ET.

If that’s still not enough, let’s throw in a comet (彗星)to the night’s festivities.

Comet 45P (it has a much longer name, but we won’t burden you with it here) is visible as it flies by Earth. The comet will get within 7.4 million miles of the planet as it makes its closest approach this weekend, according to Universe Today.

Comet 45P will be the most visible a couple of hours after the eclipse, so look to the skies again around 3 a.m. ET Saturday and find the greenish-blue light with a tail.

And don’t forget, a total big-time solar eclipse will streak across the United States on August 21st.
