阅读下列短文,从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
When I was about ten years old, I was walking down the street with my mother. She stopped to speak to Mr. Lee. I knew I could see Mr. Lee any time around the neighborhood, so I didn’t pay any attention to him. After we passed Mr. Lee, my mother stopped me and said something that has stuck with me from that day until now. She said seriously, “You let that be the last time you’ve ever walked by somebody and not opened up your mouth to speak, because even a dog will wag its tail when it passes you on the street.” Mother’s words sound simple, but it’s been a guidepost for me and the foundation of who I am.
It’s not just something I believe in; it’s a way of life. I believe that every person deserves to feel someone acknowledge their presence, no matter how humble (卑微) they may be.
At work, I always said hello to the founder of the company and ask him how our business was doing. But I also spoke to the people who cleaned the buildings and asked how their children were doing. After a few years of greeting the founder, I had the courage to ask him for a meeting. We had a great talk. At a certain point, I asked him how far he thought I could go in his company. He said, “If you want to, you can get all the way to this seat.”
I’ve become vice president, but it hasn’t changed the way I approach people. I still follow my mother’s advice. I speak to everyone I see, no matter where I am. I’ve learned that speaking to people creates a pathway into their world, and it allows them to come into mine, too.
【1】What did the author do when he met Mr. Lee?
A. He talked with somebody else.
B. He was attracted by a dog.
C. He greeted him politely.
D. He ignored him.
【2】What kind of person is the author’s mother?
A. Optimistic. B. Kind-hearted.
C. Strict. D. Open-minded.
【3】How did the company founder reply to the author?
A. He inspired him. B. He played a joke.
C. He invited him to coffee. D. He gave him the seat.
【4】What does the author think of saying hello to people?
A. It’s a way to show sympathy to people.
B. It can build connections with others.
C. It’s a must to become a president.
D. It can bring him what he wants.

阅读下列短文,从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
Annie slept in the front of the seat with her father drove through the darkness. “We’re almost there!” Dad announced cheerfully. “Soon well be observing and counting owls at the state park.” Yawning, Annie nodded and smiled. The time was 4:30 a.m. Looking out into the darkness, Annie remembered learning in school that most owls are active at night, when they hunt for food. During the day, they sleep in hard-to-find spots.
“Dad, why do you need to count owls?” she asked. “It’s important for the scientists to have current information about bird populations,” he explained. “We want to know which birds have decreased in number and whether any new kinds of birds are coming into a certain area. You and I will write down the kinds of birds that we see today and keep a record of how many times we see each kind. The we’ll send out a report to a scientific organization that is collecting about birds from people all over the county.”
Dad pulled into the parking lot of the state park. Then, with flashing in hand, they began their hike into the woods. Annie zipped up her coat and tried to keep from trembling. She had not expected the morning to be so frigid. Luckily her gloves were in her pocket.
Suddenly Annie’s father stooped and gestured for her to be still. Obeying, Annie did not take another step. She thought she heard a low crying up head. “That’s certainly a screech owl,” her father whispered. “Let’s get a look at it.” After looking more closely, Annie could see that it was a small owl. Sensing danger, the owl narrowed its eyes and pulled its feathers tightly against its body. Annie carefully wrote down in her notebook that they had seen a screech owl.
Walking a little farther, they came to a tall oak tree. “This looks like a perfect spot to attract owls,” Dad said. “I’m going to play a recording of common call of the barred owl. Maybe we can get one to answer.’ Annie could hardly believe her ear. The recorded all sounded as if the bird were asking, “who cooks for you?” Moments later Annie thought she heard a return call in distance. She held her breath and waited. Suddenly a huge bird landed very quietly on a branch above them.
Annie had long forgotten how cold it was. She stood in wonder, shining her flashlight on the bird and studying it carefully. The barred owl was nearly two feet tall. Gray feathers surrounded its dark eyes. The bird did not matter. Annie would never forget the image of the powerful barred owl.
【1】Why did Annie and her father go to the state park to ?
A. To catch owls.
B. To collect information about owls.
C. To record the call of owls and feed them.
D. To carry out an experiment on owls and study.
【2】Annie could study the barren owl carefully with the help of ________.
A. scientists
B. moonlight
C. flashlight
D. a recorder
【3】How did Annie feel when she saw the barren owl?
A. Bored.
B. Relaxed.
C. Frightened.
D. Amazed.
【4】What would be the best title?
A. The Owl Count.
B. A Study on Owls.
C. Observation of Birds.
D. A Cheerful Early Morning.
