— ________ .
A. so do I; So is it

A. would have seen
B. must have seen
C. may have seen

(2017·南京模拟)
My brother and I were in Orlando Florida to witness our first Space Shuttle Launch. The Discovery was 1 to soar at 10: 14 AM on a blue sky September day. I’d seen it 2 so many times on television, 3 now I was only minutes away from seeing it launch. And it’s the final demonstration of the 4 of success: Success Takes Off Like a Rocket.
Witnessing the Take Off:
Standing close to the Space Shuttle 5 home one unforgettable point—the Shuttle is the height of a 15-story building—it 6 4. 5 million pounds—and NASA is trying to lift it 200 miles off the ground. On TV the accomplishments look so much 7 , so much easier. Crowds of people are standing around with you to watch the Shuttle go. The countdown begins through the small 8 of hundreds of portable radios all tuned to the NASA station. It’s enough to get your heart beating 9 .
When time is up, the side booster rockets are lit up and the eight explosive bolts 10 . The first things you see are large white 11 clouds exploding away. Through the steam, you see the fire power. Then the Space Shuttle begins to inch off the pad and climb its way 12 . Thousands upon millions of pounds of 13 can hardly lift the shuttle at all. But with ever increasing ease, the shuttle picks up and roars into the sky, headed into space attaining a 14 of over 17, 000 mph.
It is within the first two minutes to launch the Space Shuttle that the great success lesson is 15 . Fact: 85% of the shuttle’s fuel is consumed within the first 2 minutes just to get the 15-story super structure to its orbital 16 .
And that’s exactly how success 17 : The first steps you take towards launching a successful career are the 18 and will require an enormous consumption of energy—a great big push. However, 19 you persist through the launch period, which can seem almost 20 for quite some time, everything gets easier and easier and your results get bigger and bigger.

Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people’s depression, physical activity, and life satisfaction. “No one will argue that an older person is better off being more active, challenged, or stimulated(刺激), ”Edwards points out. “The problem is how we promote that, especially for those without friends or help. A robotic dog could be a solution. ”
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activities before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice, ”says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has a mind of his own. ”
The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate to the robotic dog because it was metal and not furry, ”Beck says. “But it’s amazing how quickly we have given up that belief. ”
“Hopefully, down the road, these robotic pets could become a more valuable health helper. They will record their masters’ blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people’s minds. ”
【文章大意】本文是一篇说明文。为了解决现在老人的孤独问题, 研究人员研究出一种机器狗, 和老人一起生活, 提高老人的生活质量。
