第一部分: 阅读理解 (共两节,满分26分)
第一节: 阅读短文 (共8小题; 每小题2分,满分16分)
请认真阅读下列短文,从短文后各题所给的A、B、C、D四个选项中,选出最佳选项。
A
The clothes you wear. The food you eat. The color ofyour bedroomwalls. Where yougo andhowyou get there.
The people you hang around with. What time you go to bed. What do these thingshave in common? You’re asking.
They’re just a few examples of many hundreds of things that your parents controlled for you when you were a child.
As a kid, you didn’t have a say in very much that went on; your parents made decisions about everything from
the cereal you ate in the morning to the pajamas you wore at night. And it’s a good thing, too-kids need this kind of
protection and assistance because they aren’t mature enough to take care of themselves and make careful decisions
on their own. But finally, kids grow up and become teens. And part of being a teen is developing your own identity (身份认
同)---one that is separate from your parents’. But as you change and grow into this new person who makes your own decisions, yourparents have a difficult time adjusting (调整). They aren’t used to the new you yet --- they only know
you as the kid who had everything decided for you and didn’t mind.
In many families, it is this adjustment that can cause a lot of fighting between teens and parents. And issues like
the typeof friends you have or yourattitudesto partying can cause bigger quarrels, becauseyourparents still always
want to protect you and keep you safe, no matter how old you are.
The good news about fighting with your parents is that in many families the arguing will lessen as parents get
more comfortable with the idea that their teen has a right to certain opinions. It can take several years for parents and
teens to adjust to their new roles, though. In the meantime, focuson communicating with your parents.
Sometimes this can feel impossible --- like they just don’t see your pointof view and never will. But talking and
expressing your opinions can help you gain more respect from your parents and you may be able to reach compromises (和解) that make everyonehappy. For example, if you are willing to clean your room in order to stay
out an hour later, both you and your parents walk away with a good deal. Keep in mind, too, that your parents were
teens once and that in most cases, they can relate to what you’re going through.
1.In Paragraph 2. the author ______.
A.complains that parents control kids too much
B.proves that kids have no right to give their opinions
C.describes how carefully parents look after kids
D.explains parents control kids for protection and assistance
2.A lot of fighting breaks out between teens and parents because ______.
A.parents aren’t used to losing control of kidsB.teens like to have everything decided for them
C.parents get angry at teens not respecting them
D.teens are eager to develop their own identity
3.In the author’s opinion, parents control teens in order to ______.
A.prevent them from having their own ideas
B.protect them from being hurt
C.make them respect parents in the family
D.make sure that children have a good future
4.Which of the following teenagers’ questions does the author try to answer?
A.What do parents control their children for?
B.When do parents take care of their children?
C.How do I get rid of my parents’ control?
D.Why do I fight with my parents so much?
B
When I was 16 years old and in foster care (寄养中心) in Tennessee, I wanted a family very much. I asked for
the help of a judge, even the commissioner of the Department of Children’s Services, and was adopted (收养) just a
week before my 18th birthday.
We have a lot to be grateful for and this holiday season let’s not forget about the more than 415,000 youth in
foster care especially older youth These youth are the most likely to get overlooked (忽视) for adoption, but they
shouldn’t be. They need and deserve a family just as much as young children do. Making an older youth a part of
your family can bring just as much a joy as adopting a baby or a younger child.
My adoption was life changing and probably the best thing that ever happened to me. I still remember the first
gift my parents gave to me. It was a Mickey Mouse key chain with a key to their home. They told me that no matter
what happened they would always love me and I’d always have a place to come home to. This is our 17th
Thanksgiving together.... My first Thanksgiving with my family was a little overwhelming (难以应付的) with lots of extended family
including grandparents, aunts, uncles, and cousins. However, It’s when I realized that I would never have to spend
another holiday alone and that was truly an amazing feeling.

(5)有理数的乘方运算与有理数的加减乘除运算一样,首先应确定幂的符号,然后再计算幂的绝对值.
(6)任何数的偶次幂都是非负数.
2.有理数混合计算
有理数混合运算的顺序:
