The sun gives energy and the earth receives the sun’s energy. The way the earth interacts with the sun’s energy can be displayed in a picture called the earth’s energy budget(預(yù)算). It displays the sun’s energy that reaches us and how much of that energy is taken in and how much is thrown back by the earth and its air. Once the energy reaches the earth, some of it is taken by land and oceans. The amount of energy that is taken in influences the temperatures. The energy that is not taken in is thrown back to space.
Generally, the amount of energy coming in is equal to the amount of energy going out. So, we say the earth’s energy budget is balanced. If more energy was coming in than was going out, the earth’s temperature would increase. On the other hand, if too much energy is thrown back, and not taken in, we would see the earth’s temperature dropping.
Of all of the sun’s energy that hits the earth, about 67% is taken in by the land, oceans, air and clouds and about 33% is thrown back into space.
小題1:The picture above shows us how ________ hits the earth.
A. the high temperature         B. the heavy rain               C. the sun’s energy
小題2:In the 2nd paragraph, the underlined phrase “equal to ” means “______”.
A. less than                    B. the same as              C. more than
小題3:Picture ______ shows us the main idea of the last paragraph.

A.       B.      C.

小題4:If too much energy is thrown back, we will feel ______on the earth.
A. cold                     B. hot                      C. warm
小題5:The amount of energy that is _______ influences the temperatures.
A. well balanced               
B. thrown back                 
C. taken in

小題1:C
小題2:B
小題3:B
小題4:A

Most kids hate doing housework. However, not all hope is lost. There are some things that you can do to get your kids to help you clean your house. If you are struggling with the chores (家務(wù))and need your kids to help you, take a look at some of the creative ways in this article.
If you are dealing with older kids, you may want to try the allowance deal. You can give your kids a list of chores that need to be done each week. If they complete these chores, you can give them some money. You can also break the list down and tell them they will get so much for each chore that is finished. Older kids , who like to do things on weekends or buy things like video games, will work hard to complete their chores and earn their money. This is also teaching them responsibility. This is teaching them that they must work for what they want.
If you are dealing with younger kids, you may want to go with the rewards chart(獎勵圖表). This is where you design a chart and list their chores on the chart. For each chore they complete, you can put a red flower beside it. For the rewards, you canalso do a number of things ,such as going to the park, going out to eat, buying a DVD or something similar. The rewards would be up to you because you know what your kids like.
For real small kids, you can turn it into a game. When kids were much younger, you can teach them to dance around and sing as you cleaned. The kids loved it and would do a wonderful job at picking up their toys. So, consider turning cleaning into a game for the real small kids.

Height is just one of the features your genes (基因) decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too. But if you have questions about how tall you’re going to be, ask your doctor if he or she can help you find them out.
But genes don’t decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential (潛力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
It’s natural that you’re wondering how fast you should grow. There’s no perfect or right answer. Generally speaking, kids grow about 6 cm a year between age 3 and the time when they start puberty .
Your doctor will know how your growth has been going over the years. 2 cm here and 3 cm there make a little difference to the height you’re at now. How have you been growing up to this height?What other changes may your body be going through?
Don’t be amazed if you seem to have grown a lot in a very short time. Everyone has a growth spurt (高峰) during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later — between 7 and 13 for girls and 9 and 15 for boys.
You’ll usually begin to notice that you’re growing faster about a year after your body starts to show the first changes of puberty.
小題1:If you want to know how tall you should grow, _______.
A.you should have enough exercise
B.you can ask doctors for help
C.you should take some special medicine
D.you can record your growth during puberty
小題2:The Chinese for the word “ puberty ” is _______.
A.童年時期B.嬰幼兒時期
C.習慣養(yǎng)成期D.生長發(fā)育期
小題3:This passage is mainly about ______.
A.how the genes work in your body
B.how your parents’ height influence you
C.how you look like your parents
D.how you grow to a certain height
小題4:After reading this passage, we can explain ______.
A.how good it is to be a doctor
B.how much sleep time we need
C.why genes can’t decide everything
D.what healthy diet is
小題5:Which is NOT mentioned in the passage?
A.Your height most probably depends on how tall your parents are.
B.Girls’ age for starting puberty is usually earlier than that for boys’.

Is it difficult for you to get up in the morning? Hiroyuki’s bed will solve your problem! Here is how it works.
  The bed is connected to an alarm clock(鬧鐘). First, the alarm clock rings. You have a few minutes to wake up. Next, a tape recorder in the bed plays soft music. The tape recorder in Hiroyuki’s bed plays a recording of his girlfriend. She whispered in a soft voice, “Wake up, darling, please.” After minutes later, Hiroyuki hears a recording of his boss. His boss shouts, “Wake up at once, or you’ll be late!”
If you don’t get up after the second recording, a mechanical(機械的) “foot” in the bed will kick you in the head. The bed waits a few more minutes. What! You’re still in bed! Slowly the top of the bed rises higher and higher. The foot of the bed goes lower and lower. Finally you slide(滑落) off the bed and onto the floor. You are out of bed awake!
  Hiroyuki’s bed is not in stores. There is only one bed — the bed Hiroyuki made for a contest(比賽). Maybe someday a company will make Hiroyuki’s bed and sell it in stores. Maybe people will buy millions of beds. Then Hiroyuki will be rich. If the bed makes Hiroyuki rich, he won’t need to work, and he won’t need to get up early!

 School education(教育) is very important and useful. Yet, no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself than to memorize some facts or a formula(公式). It is actually quite easy to learn a certain fact in history or a formula in math. But it is very difficult to use a formula in working out a math problem.
Great scientists didn’t get everything from school. For example, Edison didn’t even finish primary school. But they were all so successful. They invented so many things . The reason for their success was that they knew how to study. They read books that were not taught at school. They would ask many questions as they read. They did thousands of experiments. They worked hard all their lives, wasting not a single moment. Above all, they knew how to use their brain.
小題1:  According to the passage, the most important thing a teacher should do is _______.
A.to teach his students everything he knows
B.to teach the students how to think
C.to know everything they want to know
D.to teach the students how to work out a math problem

C
Why are you study habits different from those of your friends? Why do you seem to learn faster in some classes while more slowly in others? One reason you may not know is that people have different types. Scientists say there are three different learning types: Visual(視覺型),Auditory(聽覺型),and Kinesthetic (動覺型)。
Visual learners learn best by seeing. If you seem to easily remember information from pictures, graphs(圖表),and videos, you are probably a visual learner. You’re not good at copying down what the teacher says in class. Never mind. You can draw graphs or pictures instead, if you find that works better for you.
Auditory learners learn best by hearing. If you seem to easily remember things by hearing them, then you are probably an auditory learner. You must listen carefully while the teacher is speaking because it’s the easiest way for you to learn . Sometimes you may find that taking notes tops you from listening carefully. After class, you can write down what you remember or borrow your friend’s notes to copy.
Kinesthetic learners learn best by doing. If you seem to learn best by working with your hands, you are probably a kinesthetic learner. Taking notes by writing can make you pay close attention to information as you receive it. Of course, you can learn best by making full use of labs or other class activities.
Hope you learn better by knowing what your personal learning type is.
小題1:There are____________ different learning types according to the passage.
A.twoB.threeC.fourD.five
小題2:Jude can remember the words of a song quickly by listening to it once or twice. She might be a /an ____________ according to the passage.

A.Remembering information from videosB.listening teachers in class
C.drawing graphs or picturesD.doing things with their hands

Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth (光滑的) rub together to make heat energy. The faster you rub two things together, the more friction you can make. Let’s discover friction!

WHAT YOU’LL NEED:
★Soap                ★Water           ★Your hands
WHAT TO DO:
★Make sure your hands are dry.
★Rub your hands together until you feel the heat of your hands.
★Now, use soap and water to get your hands very slippery (滑的).
★Try to make friction happen while your hands are slippery.
★Please write down what has happened.
LET’S TALK!
Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won’t make very much friction and your hands won’t get so hot.
DID YOU KNOW?
★Friction happens when you stop your fast running bike.
★Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn’t know it. ___  __?         Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not hot, touch the tires (輪胎) of the car before and after a short drive to see how much warmer they get from friction.
小題1:You’d better make your hands ______ to get heat when you rub them.
A. slippery                 B. dry                  C. wet
