Have you been exercising and eating healthy，but when you step on the scale（稱），it says you've gained a few pounds？ "That's normal，and it doesn't mean that your workouts（鍛煉） are not effective"，says Jeffrey A.Dolgan，an exercise physiologist in Miami Beach，F(xiàn)lorida.
   "A person's scale mass （質(zhì)量） is a combination of muscle（肌肉），fat，bone，blood，and even the air that we carry in our lungs，" he says. "Immediately after a workout routine，the percentage of mass in each body part can shift as much as 15 percent.So if you're gaining weight while working out and eating healthy，it's probably not the type of weight gain that you think it is.
   The scale can't tell you how much of your body weight is muscle or fat，which means if your goal is to improve your fitness level，the scale is not the best tool for measuring improvements.When you start to change your body composition with your workouts — by building more muscle mass and decreasing your body fat — your scale weight may increase，while your body fat percentage may decrease.These changes happen over weeks and months （not hours or days） so the scale is useless when tracking them.
   You may argue that you weigh a few pounds less after a high intensity （強(qiáng)度） training class.Don't get too excited—it's just water loss due to sweat.Water makes up approximately 65 to 90 percent of a person's weight，and variation in water content of the human body can move the scale by ten pounds or more from day to day.
   So ignore the scale and pay more attention to objective measurement tools like body composition.Keep in mind that if you're exercising but gaining weight，you may actually look slimmer.

  • 菁優(yōu)網(wǎng)1．"Snowplow（掃雪機(jī)）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       "Helicopter （直升機(jī)）parenting' means monitoring their kids' every activity，which is out of date.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.
