   Sea cucumber
   Sea cucumber are strange animals living at the bottom of the sea.They wear brown or white green coats.When summer comes,they stay deep to sleep because they are afraid of heat.And when it is autumn,they move to shallow (淺的) water and get their food.

  • 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.
