IV. 阅读理解

When the explorers first set foot upon the continent of North America, the skies and lands were alive with an astonishing variety of wildlife. Native Americans had taken care of these precious natural resources wisely. Unfortunately, it took the explorers and the settlers who followed only a few decades to decimate a large part of these resources. Millions of waterfowl

(水禽) were killed at the hands of market hunters and a handful of overly ambitious sportsmen. Millions of acres of wetlands were dried to feed and house the ever-increasing populations, greatly reducing waterfowl habitat (栖息地).

In 1934, with the passage of the Migratory Bird Hunting Stamp Act (Act), an increasingly concerned nation took firm action to stop the destruction of migratory (迁徙的) waterfowl and the wetlands so vital to their survival. Under this Act, all waterfowl hunters 16 years of age and over must annually purchase and carry a Federal Duck Stamp. The very first Federal Duck Stamp was designed by J.N. “Ding” Darling, a political cartoonist from Des Moines, lowa, who at that time was appointed by President Franklin Roosevelt as Director of the Bureau of Biological Survey. Hunters willingly pay the stamp price to ensure the survival of our natural resources.

About 98 cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase wetlands and wildlife  habitat for inclusion into the National Wildlife Refuge System — a fact that ensures this land will be protected and available for all generations to come. Since 1934, better than half a billion dollars has gone into that Fund to purchase more than 5 million acres of habitat. Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever initiated.

1. What was a cause of the waterfowl population decline in North America?

A. Loss of wetlands.                B. Popularity of water sports.

C. Pollution of rivers.               D. Arrival of other wild animals.

2. What does the underlined word “decimate” mean in the first paragraph?

A. Acquire.          B. Export.          C. Destroy.         D. Distribute.

3. What is a direct result of the Act passed in 1934?

A. The stamp price has gone down.        B. The migratory birds have flown away.

C. The hunters have stopped hunting.      D. The government has collected money.

4. Which of the following is a suitable title for the text?

A. The Federal Duck Stamp Story        B. The National Wildlife Refuge System

C. The Benefits of Saving Waterfowl      D. The History of Migratory Bird Hunting

V  读后续写

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

I reached into my backpack, feeling for my cellphone. I was tired of Aunt Letty talking on and on about her chickens, horses and cows. Worse, I was afraid of having to spend spring break at her farm.

In spite of my protest (反对），my parents decided that spending time at the farm would be a great experience for me. My parents both grew up on farms and believed that responsibility, hard work and respect for the land were valuable lessons. ?,Lessons you need to learn, son.” they said.

”So, have you ever ridden a horse?” Aunt Letty asked, trying to turn my attention away from my phone.

no. But I’ve seen horses on TV,M I answered, absent-minded.

”Well, we’ve got a nice horse I think you’ll like. Hercules--- sounds like a beast, but he’s a gentle giant. The other animals have names too, but don't worry, you won't have to remember their names. If you show up at the gate with feed, they're happy!' she said smiling.

I glanced at my aunt, angry that I was expected to work. Vacations were meant for sleeping late, playing video games, and maybe skateboarding. I tried to text a friend.

"Phones don't work well out here. With all the hills and valleys, it's hard to get a connection."

I continued texting, but she was right --- there was no cell reception.

The next few days were busy. We had breakfast before dawn. Then we went out to the barn to get the feed while the animals waited to be fed. The afternoons were occupied with hauling (搬运）hay, clean-up, and caring for the animals. The animals depended on Aunt Letty, but they also provided her with affection and necessities such as eggs, milk and cheese.

At dusk, when the farm was finally quiet, Aunt Letty stretched her arms out and said, "Just take a deep breath of the sweet country air!" I, exhausted, was unable to appreciate my work.

注意：

1. 所续写短文的词数应为150左右；

2. 应使用5个以上短文中标有下划线的关键词语；

3. 续写部分分为两段，每段的开头语已为你写好；

On the fourth day, Aunt Letty announced, "It's time to meet Hercules.
