People often think of the North Pole (北极) and the South Pole as similar frozen (冰冻的) wastelands. They are both places with very cold temperatures and few people live there. However, the North and South Poles are not much alike as people may imagine.
The North Pole has no land, only thick ice. Temperatures seldom go above 32°F, at which water turns into ice. Most of the time, it stays below zero. In winter temperatures are usually as low as -30°F.
Although conditions were very poor, people tried for many centuries to reach the North Pole. About 100 years ago, two men, Robert Peary and Mathew Henson, were able to get to this environment full of troubles and difficulties. They reached the North Pole on March 8th, 1909. It was really a hard trip for them.
There are few things more dangerous than crossing the Arctic (北极圈) on foot. People who stayed there may face many problems: very cold temperatures, sudden storms, and even hunger. Most of the area is uninhabited. Few people can live in such a difficult place.
People might think that with such low temperatures for most of the year, the ice would be thick and hard. However, this is not true in the Arctic. The movement of the ocean water under the ice may often cause many different changes on the surface. Sometimes the ice breaks into two opening lanes of water (水道) called “leads”. Anyone who falls into a lead can be frozen to death in a few minutes.
31．According to the passage, what happened about 100 years ago
A．Two men succeeded in getting to the North Pole.
B．Temperatures in the North Pole went above 32°F.
C．The environment in the North Pole suddenly became worse.
D．The North Pole changed into thick ice because of the temperatures.
32．What does the underlined word “uninhabited” probably mean in Chinese
A．气候恶劣的 B．充满危险的 C．困难重重的 D．无人居住的
33．The reason for the ice to break into two opening lanes of water is __________.
A．that the temperature suddenly drops
B．that the water under the ice is frozen
C．that the ocean water under the ice moves
D．that the surface is covered with lots of ice
Who is the greatest teacher in Chinese history Many people will think of Confucius, whose birthday was September 28. Although he lived over 2,000 years ago, people still remember and respect him for his contribution（贡献）to the education today.
Confucius lived in the Kingdom of Lu, which lies in Shandong Province. He lived during the Spring and Autumn Period. He had a hard childhood. His father died when he was only 3. His mother brought him up. As a child, he had to work to help his mother, but young Confucius didn’t give up studying. He visited many famous teachers and learned music, history, poems and sports.
Later, he became a teacher and started the first public school in Chinese history. At that time only children fromnoblefamilies could go to school, but Confucius believed everyone should go to school if they wanted to learn. He had about 3,000 students in his lifetime.
Today, people still follow Confucius’ lessons. He told us that we all have something worthy to be learned. “When I am with three people, one of them must be better than me in some areas. I choose their good qualities and follow them.”
He also taught us that thinking is very important in study. “All study but no thinking makes people puzzled（困惑的）. All thinking but no study makes people lazy.”
Confucius is not only a great teacher, but also a famous thinker with wise thoughts about the world and society. His most important teachings are about kindness and good manners. “A person should be strict with himself, but be kind to others.” he said.
34．How did Confucius learn music, history, poems and sports when he was young

A．All study but no thinking makes people puzzled.
B．No one has something worthy to be learned.
C．All thinking but no study makes people lazy.
D．A person should be strict with himself, but be kind to others.
As a mountain, 1,642-foot squad Peak isn’t that impressive (给人深刻印象的). But its views attract many hikers (远足者). Hear Grant, a college student at Ithaca College, was one of them.
While waiting for his mother one day in August 2019, Grant watched other hikers enjoy the view. One hiker, dressed in pink, was looking over the lip of the cliff (悬崖) with her husband.

After 15 minutes of climbing over large rocks, pushing past bushes, and slipping (滑) down loose earth, Grant found a pink figure. The woman had fallen about 75 feet. Luckily, she was alive (活着的).
“Paula! Paula!” Grant shouted. The woman didn’t reply. She was badly hurt. Grant called the police to report her location (位置). She kept trying to move, and every time she moved, she slipped a little more. Afraid that in her unclear state of mind she might fall off the rock to her death, Grant climbed on all fours up a tight and narrow path by digging into the earth with his fingers and feet until he reached Paula.
Paula was moaning (呻吟), almost senseless. Grant gently put her hand in his, trying to keep her mind off the pain by keeping asking her questions: “Where are you from Do you have kids ” Soon, they were joined on their perch (歇脚处) by another hiker named Simon.
About 45 minutes later, the first rescuers (救援者) arrived. Paula and her husband were flown to a hospital. Five hours after the woman in pink had fallen, Grant was back on top of squad Peak.

Dear schoolmates,
Elephants are the largest mammals on land. They can live as long as 80 years old. However, these days the number of elephants is becoming much smaller. People cut down forests, so they are losing their homes. People also kill them for their ivories. Elephants are in great danger. I think we should try our best to protect them. First, we should help make rules to stop people from killing elephants. Second, we shouldn’t cut down trees. Third, we shouldn’t buy anything made of ivories.
I believe everyone’s contribution can make a big difference.
Wang Peng
