We have always been interested in the moon.2000 years ago, people already knew that the moon moves around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky.
When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on the earth. This was because they believed the moon had once been a planet that had been caught in the earth’s gravity millions of years earlier.
In 1969, moon rocks werefinally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information.
After years of study, most scientists now think that the moon was once part of the earth. They believe very early in its history, maybe 4 billion years ago, something about the size of Mars hit the earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.
In the future, even thought our ideas about the moon may change again, we will still be interested in it.

Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain near my house. Walking together, my father and I used to have a lot of conversations through which I learned lessons from his experiences. He always told me, “You should have goals like climbing the mountain.” Without the mountain-climbing that we both enjoyed, we couldn’t have enough time to spend together because my father was very busy. I really got a lot from the mountain-climbing. It gave me time to talk with my father and to be in deep thought as well as develop my patience.
Once we climbed a very high mountain. It was so challenging for me because I was only ten years old. During the first few hours of climbing, I enjoyed the flowers and trees, and the birds’ singing. But as time passed, I got a pain in both of my legs. I wanted to quit climbing, but my father said to me, “You can always see a beautiful sky at the top of the mountain, but you can’t see it before you reach the top. Only there can you see all of the nice things, which is just like your life.”
At that time, I was too young to understand his words. But later after that, I got to know the meaning of hope in life. I found myself standing at the top of the mountain, and the sky was as clear as crystal.
小題1: The passage tells us that mountain-climbing was ______ for the father and the son.
A．hardB．enjoyableC．painfulD．comfortable

A．You will get all you need at the top of the mountain.
B．The sky is always as clear as crystal.

D．Never give up half-way.

A．the writer was very successful in his life
B．the writer reached the top of the mountain
C．though the writer was young, he could understand his father
D．the writer used to stop half-way when he climbed the mountain

“What is success”? Mr. Black asked his 6th grade business class. It was his opening conversation for the first class of the term.
“Success is riding in a sweet car, watching an 80-inch((英寸) TV, and living in a place with at least twelve rooms.” One student answered, earning（博得）laughs from all the students.
Mr. Black smiled, but shook his head. “Tom, that is excess(過量). That is not success.”
“How about being able to provide for your family?” A blonde girl named Sandy in the front suggested as an answer.
“Now we’re getting closer,” Mr. Black smiled, “but try thinking about what you need and what you want.”
“Getting everything you want.” Tom shouted out an answer again, trying for more laughs.
Mr. Black sighed（嘆氣）.“ I believe we’ve already talked about excess versus(與…比較) success.”
“Getting everything you need, but some of what you want?” James, sitting in the back wondered aloud.
“Quite right!” Mr. Black clapped. “Success is getting everything you need and some of what you want. The more you get that you want, the more successful you are. You do reach a point where you are living in excess, though.”
“What does this have to do with business?” Tom asked. It seemed if it wasn’t funny, he wasn’t happy.
“Well, Tom, think of it this way: the point of business is to make a living to support your family. Once you have properly seen to (確保) their needs, you can then seen to getting the extras that you want.”
“What if I don’t have a family?” he continued to be difficult.
“Then you have to provide for yourself, a family of one.”
“He has goldfish to think about!” Peter, Tom’s friend, shouted out.
“Then he needs to provide for a family of one with a fishbowl.” Mr. Black corrected himself.
Tom nodded, satisfied with that answer.
“So in the next nine weeks, we’re going to study basic business situations, like having a checking account and understanding credit cards（信用卡）.”
Tom rubbed his hands together excitedly. “When do we get to start spending?”
“You already are, Tom. You’re spending time with us!” Mr. Black laughed. “Now, let’s see what you guys know about credit cards…”

One day I got into a taxi and we took off for the airport.
We were driving in the right way when suddenly a black jeep jumped out of a parking space right in front of us. My taxi driver had to stop the car at once, and missed the other car by just inches! The driver of the other car started shouting at us. My taxi driver just smiled and waved at the guy, and I mean, he was really friendly.

Paul Nicklen waited patiently on a sheet of ice in the Arctic.  He was there to take pictures for National Geographic. Finally, he saw something big and white. It was a polar bear, swimming towards him in the icy water.
Paul lay down-on the ice to get a better photo, but the polar bear jumped out of the water and tried to attack him! Luckily for Paul, the ice cracked or broke and the bear fell back into the water The polar bear wasn’t so lucky. It couldn’t get a meal and had to swim farther away to find food.
To understand the polar bear’s problem, you need to know two things about the Arctic. First, the Arctic is mostly ocean. Second , ice cover a lot of the Arctic Ocean. In winter, the ice form a thick, white sheet, but in summer, the ice becomes thinner and break into pieces. Sea ice is the key to survival for Arctic animals. However, because of global warming, Arctic temperatures are rising and polar ice is melting.
Polar bears need ice to hunt seals, their favourite meal. They stand on the ice wait for the seal to come up for air. As Arctic ice melts, polar bears have to swim farther to find ice floes, or large pieces of floating ice. Sometimes, bears have to swim more than 200 km to find an ice floe. Some bears cannot swim that far and sadly they drown.
On his last trip, Paul Nicklen saw three dead bodies of polar bears. Before global warming threatened Arctic ice, a dead bear was a rare sight, Paul is sad to see the dead bodies, wildlife experts thinks global warming will have a terrible effect on polar bears. In the future, polar ice will continue to shrink and endanger the bear. Some scientists believe 65 percent of the world’s polar bears will disappear by 2050. in other word, polar bears are in great danger.
