When you look at the sky at night, the moon looks bigger than the stars. Actually, the moon is much smaller than the stars and the sun. It’s much smaller than the earth. But the moon is much closer to us than any star. That is why it looks so big. If you hold a coin close to your eye, it looks big. If you look at it across the moon, it looks small.
The moon moves around the earth. It makes one trip in about four weeks. The moon looks flat to us. But it is a round ball, like the earth.
People once thought the moon had fire on it. They thought the fire made it bright. Now we know the moon is like a mirror. It gets its light from the sun.
Our sunlight comes from the sun, too. What is the sun? The sun is a star. The stars we can see have their own light. There are many big stars we cannot see. Their light had burned out. Others are still bright, but they are so far away that we cannot see them. The sun looks bigger and much brighter than other stars because it is the nearest of all stars. The sun and the other stars we see are very hot, but the air around us saves us from the heat of the sun.
The sun gives us light and warmth. It makes plants grow and turns leaves green. It makes life possible on our earth. It is a life giving star.
小題1: It takes _______ for the moon to go around the earth.
A.more than a weekB.nearly a monthC.half a yearD.more than a year
小題2: The moon is bright because _______.
A.there is some fire on itB.it is near the sun, too
C.there is a big mirror on itD.it can get light from the sun
小題3: The passage tells us _______.
A.the sun is not the biggest starB.the sun is bigger than any other star
C.only the sun can shineD.the sun is one of the farthest stars to us
小題4: Why do we call the sun "a life giving star"?
A.Because it gives us warmth.
B.Because there are some living things on it.
C.Because plants and animals can’t live without it.
D.Because people have to live in the dark without it.

小題1:B
小題2:D
小題3:A
小題4:C

小題1:本文第二段前兩句為The moon moves around the earth. It makes one trip in about four weeks.意思為月球繞地球要花費四周的時間,也就是幾乎1個月的時間,故本題選B。

Oriole’s Nest
Picky, Picky
Scientists have no idea exactly why birds choose certain objects to build their nests. But scientists know that the main reason birds build nests is to keep their babies safe, warm and healthy.
Baby birds grow faster and are healthier when they are warm. They also learn to fly and leave the nests sooner than birds without warm homes.
What A Yarn (紗)
Yarn is big on an oriole’s shopping list during nest building. Scientists are still trying to work out why so many birds choose white yarn over other colors for nest building.
Scientists think that the white objects remind birds of cotton fluff (絨毛) they find in the wild.
Do It Naturally  
Even though birds can help us recycle some of our junk by using it to build nests, they also need to use lots of natural things. Long grass, dried sticks, spider’s silk and mud are some of the natural ingredients that are good for nests, too.
You can make a collection box of things to leave for birds so they can help themselves. Hang a small plastic box with holes on a tree branch. Fill the box freely with nest building goodies. Hang the box on a tree and watch birds climb on board to pick through the junk to find their treasures.
Warning: Don’t let the birds turn into a tasty treat. Keep your bird station away from places where cats hang out.
For The Birds!
Stop! Don’t throw all that garbage out! Give some to the birds. Look and see how your old junk can help beautify and warm a bird’s new home.
小題1:The baby birds with warm homes are able to _____.
A.choose right objectsB.leave the nests sooner
C.build good nestsD.learn to fly higher
小題2: What can people make for birds to build nests?
A.Holes on the tree.B.Food out of the rubbish.
C.A warning board.D.A collection box of things.
小題3:What can we learn from the passage?
A.Birds build nests to store things.
B.Birds regard white objects as cotton.
C.Birds and humans can help each other.
D.Birds and cats fight against each other.

Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By sitting on exercise balls instead of chairs, teachers find students' posture (姿勢) and attention improve.
Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December 2008. "The students love them", she says. Pownall took a survey of her students. She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning.
The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates not only teachers but also students on how to use them. "Our products are used in 24 states, three provinces in Canada, Puerto Rico ('波多黎各) and Japan," says Witt. "Research shows that sitting on the balls makes them sit up straighter. You can slouch (低頭垂肩地坐) on a ball," says Witt, "but it feels awful." Because the students are moving, their blood (血液) increases. That carries more oxygen (氧氣 to the brain (大腦), so the kids have more energy and can focus longer.
"Furthermore, they're fun." says Pownali.
小題1: What will happen if a student sits on a chair all day in school? The student will _________.
A.pay more attention to his lessons B.be fun
C.like to move aroundD.sit up straighter
小題2: How long has Dottie Pownall used the balls?
A.About three years. B.Only one year.
C.In 2008. D.Since he was a fifth-grade teacher.
小題3: In how many countries are the balls used as the students' chairs?
A.Four. B.Three. C.Two. D.One.
小題4:Teachers choose balls instead of chairs because sitting on balls helps the kids___________.
A.improve the students' posture and attentionB.slouch on the chairs
C.have funD.Both A and C are correct answers.
小題5:Which is better for kids to study in class, sitting on a chair or sitting on a ball?
A.Sitting on a chair.B.Sitting on a ball.
C.They are the same.D.We don't know.

Are you carrying too much on your back at school? I’m sure lots of children of your age will, say "Yes". Not only the students in China have this problem, but children in the United States also have heavy school bags.
Doctors are starting to worry that younger and younger students are having back and neck problems as a result of schools bags being too heavy for them.
"It’s hard for me to go upstairs with my bag because it’s so heavy, "said Rick Hammond, an 11-year-old student in the US.
Rick is among students who have common school bags with two straps(帶子) to carry them, but many other students choose rolling(有滾輪的)bags.
But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.
But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight(重量).
Scott Bautch, a back doctor, said children under Grade 4 should stay with 10 % . But it is also important that older children don’t stay with over 15 %, because their bodies are still growing. "Children are losing their balance(平衡) and falling down with their school bags, "he said.
Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.
