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.

（1）What can we know from Dolgan's words from paragraph 2？

A．Your weight changes little during a day.
B．Your scale mass is affected by many factors.
C．Your workout is not effective if you gain weight.
D．Your weight is determined only by muscle and fat.
（2）What will most probably happen after you exercise and eat healthy for 3 months？

C．100 pounds.
D．140 pounds.
（4）Which of the following could be the best title for the text？

1．How to Raise a Child Who Loves Reading Give your kids good books to read.
   By "good" I mean quality literature that makes kids think，not just entertains them.Some books can be fun.（1）

Keep away from lightweight （內(nèi)容平庸的） books，because they may teach them to turn away from anything that makes their brains work too hard.A diet of lightweight books does not promote the patterns of thought that produce intellectual and personal excellence.
   （2）

Kids love listening to their parents read，even as they get older，so don't stop reading aloud to your children just because they can read on their own.This is a perfect opportunity to challenge their abilities，vocabulary and worldviews by reading books.
   Remove distractions （使人分心的事物）.
   With hand-held devices （3）

Parents should have these devices powered down and phones put away，and ask them to pull out their books.Once kids finally get into their books，it creates the same quiet，peaceful atmosphere home.
   Talk about books with your kids.
   （4）

Ask every family member，even the youngest，what they have read that day and what they've learned from it.This will arouse discussion and debate about the issues raised in the books.
   Give our kids paper books，not e-books.
   Studies have shown children keep information better when they read it on paper，as opposed to a screen，so avoid giving your child e-books to read.A paper book allows them to create a relationship with the book，to reread and to become familiar with a book's feel and smell.（5）

A．Read aloud to your kids.
B．Take chances to challenge your kids.
C．That's where parental responsibility comes in.
D．All these are very real parts of the reading experience.
E．Parents should inform their kids of the harmfulness of hand-held devices.
F．The dinner table is a great place to start reflective conversations about books.
G．But it's important to teach kids to appreciate books that may take effort to consume.
