You may have heard adults say they are uncomfortable in the morning without a cup of coffee.One reason they may feel that way is that coffee contains caffeine（咖啡因），Caffeine appears naturally in coffee，tea，and cocoa beans，which are used to make chocolate.But now food makers are adding it to many products，from potato chips to water.
   The US government is especially worried about the problem.That's why the Food and Drug Administration（FDA）is studying the health effects of caffeine on young people.Studies show that too much caffeine can make people nervous and unable to sleep.What's more，caffeine is habit-forming.Those who consume it regularly and stop suddenly may experience headaches and feel tired.
   One of the biggest concerns is the large amount of caffeine added to so-called energy drinks，like Red Bull.A 12-ounce can of cola has about 35 milligrams of caffeine.A similar serving of Red Bull contains more than three times that amount.
   The Institute of Medicine is also working on caffeine-safety measures."Teenagers should not drink beverages that contain caffeine.They should be aware of caffeine's effects on health and on how the brain works.Take，for example，teenagers who consume caffeine to stay awake and study for a test.They will remember less of what they just studied，"said Stallings，a member of the institute.
   Companies that make products with added caffeine claim they do not advertise them to kids.However，there is no law to stop children from buying them.So the FDA needs to set limits on caffeine，especially in energy drinks.As for added caffeine in foods，the government should just say no.If not，the amount of caffeine should be printed on food labels to remind consumers.The government must do that.
   Doctors say kids should avoid caffeine.If you need extra energy，try these natural boosters：eat right，exercise.and get plenty of sleep.

  • 菁優(yōu)網(wǎng)1．"Snowplow（掃雪機）parenting" is the newest parenting style that can include parents booking their adult children haircuts，calling their college kids to wake them up so that they don't sleep through a test，and even calling their kids' employers.
       "Helicopter （直升機）parenting' means monitoring their kids' every activity，which is out of date. " Claire Cain Miller and Jonah Engel Bromwich wrote in The New York Times. "Some rich mothers and fathers now are more like snowplows：clearing any problems in their children's path to success so that they don't have to meet failure or lose opportunities. "
       There is a mother who started a charity in her son's name to try to raise his chances of being accepted to the college.One set of parents spent years helping their daughter avoid foods with sauce，which she didn't like.Once she got to college，she had problems with the food in her school because it was all covered in sauce.
       A survey says that three-quarters of parents of children between the ages of 18 and 28 ask for doctor visits or haircuts for their children，and 11% say they would call their kids' bosses whether their children are having an issue at work.
       As reported，wealthy parents try to get their children into top colleges by giving a large amount of money to a school，such as paying for a building.This parenting has become the most popular way to raise children，whatever the income，education，or race is.
       Julie，a teacher at Stanford，told the Times that "snowplow parenting" is not a reasonable approach. "The parents should prepare the kid for the road，instead of preparing the road for the kid，" she said.

    （1）How does Julie like "snowplow parenting"？

    A．It is unreasonable.
    B．It is advanced.
    C．It is accepted by teachers.
    D．It is refused by rich people.
    （2）What is the character of "helicopter parenting"？

    A．Parents make kids popular.
    B．Parents provide little money for kids.
    C．Parents ask kids to care for themselves.
    D．Parents watch over kids' every activity.
    （3）What should parents do according to Julie？

    A．Do as wealthy parents do.
    B．Make kids be prepared.
    C．Make roads be prepared.
    D．Do as little as possible.
    （4）What's the best title for the text？

    A．Helicopter Parenting.
    B．The Similarity in Parenting.
    C．A Research on Parenting.
    D．A New Kind of Parenting.

  • 2．How good are you at maths？Some people love the challenge of algebra（代數(shù)）or enjoy working out number puzzles.Maths is all around us，from working out how to share the bill after a meal，to calculating your family bills.But many are afraid of the moment when they have to deal with numbers and figures and feel a real sense of worry and confusion.It can seem frightening，but this maths anxiety is perfectly normal，and you're definitely not alone.And anyway，our worries and fears don't necessarily reflect our ability.
       The problem really starts in childhood，at school.Research has found that maths teachers who are nervous about teaching the subject can pass on their anxiety to the pupils，and girls may be more likely to be affected.The Programme for International Student Assessment found around 31% of 15—and 16—year—olds across 34 countries said they got very nervous doing maths problems，33% said they got tense doing maths homework，and nearly 60% said they worried that maths classes would be difficult.Shulamit Kahn，a professor from Boston University，believes that giving students，particularly girls，good role models is critical，especially at a young age.She thinks the key is to get people，especially women who love maths，to teach younger children
       Writing for the BBC，David Robson says， "It's not clear why maths causes so much fear compared to geography.But the fact that there's no room for playing tricks might make you more worried about underperforming." And once we assume that we're not a maths person，we avoid solving things that we probably could do.
       Psychologists have been trying to work out why mental arithmetic（心算）can bring us out in a sweat.That seed of fear may come from many sources，but some suggest that voicing your fears can loosen their control over you.They also suggest encouraging children to see a maths test as a challenge，not a threat.Most importantly，we need to think positively about maths and give it a second chance.

    （1）What is the author's understanding of maths anxiety in paragraph 1？

    A．It happens when you have to pay bills after a meal.
    B．It actually reflects one's poor performance in maths.
    C．Only students often suffer from this sense of worry.
    D．People normally have it when dealing with numbers.
    （2）What may cause students' maths anxiety according to the research？

    A．The particular feature of maths.
    B．The fear of failure in maths tests.
    C．Students' dislike of learning maths.
    D．Maths teachers' lack of confidence.
    （3）What can we infer from David Robson's words？

    A．Geography seldom causes worry.
    B．Slow students have maths anxiety.
    C．Dishonesty is difficult in maths tests.
    D．Maths students like number puzzles.
    （4）What is the best way to get over maths anxiety？

    A．Speaking out your fears in public.
    B．Employing female maths teachers.
    C．Having a positive attitude to maths.
    D．Viewing maths tests as a challenge.
