Unit 4 The Wonders of Nature (Period 3) Section A (Grammar Focus-4d) Ⅰ．阅读理解。 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℉, at which water turns into ice. Most of the time, they stay below zero. In winter temperatures are usually as low as 30℉. Although conditions were very poor, people tried for many centuries to reach the North Pole. About 100 years ago, two men, Robert Peary and Matthew Henson, were able to get to this environment full of troubles and difficulties. They reached the North Pole on April 6th, 1909. It was really a hard trip for them. There are few things more dangerous than crossing the Arctic (北极) 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. 1．This passage is probably from a ________. A．book review B．science book C．school report D．computer magazine 2．According to the passage, what happened about 100 years ago? A．Two men succeeded in getting to the North Pole.

A．the temperature suddenly drops B．the water under the ice is frozen C．the ocean water under the ice moves D．the surface is covered with lots of ice 5．What does this passage mainly talk about?

Ⅱ．任务型阅读。 Last summer, I went to a river trek (徒步旅行) with some British friends. The river was not wide, but it was running fast. The rocks in the river were so slippery (湿滑的) that it was hard for us to walk. We walked carefully, but our shoes and trousers were still wet. I was getting very cold and tired. I wanted to stop, but when I saw other kids moving so fast, I felt sorry. This encouraged me to keep following them, even though I was far behind. It was even more difficult during the last part of the walk. I became so tired that I lost my footing and fell several times. But with the help of my friends, I got to my feet and kept going each time I fell. Finally, we arrived by a waterfall. Everybody jumped into the water from a high rock. When it was my turn, I was afraid and tried to hide around a corner. My friends noticed this and encouraged me, “Come on, Kevin! You can do this!” With my eyes closed, I jumped into the water. Although I’m not as strong as my British friends, I completed our trek. This experience made me realize that perseverance (坚持不懈) was, is, and will always be important to everyone in life. 根据短文内容，回答下列问题。 6．Why was it very hard for them to walk on the rocks? （不超过10个词） _______________________________________________________________________ 7．What did Kevin do when it was his turn to jump into the water? （不超过10个词） _______________________________________________________________________ 8．What did Kevin learn from this experience? （不超过15个词） _______________________________________________________________________ Ⅲ．语法填空。 Do you know the largest nature park in China?
