第二节(共5小题;每小题2分，共10分)
根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
When you sleep, do you ever realize that you are dreaming? If yes, then you have had a lucid dream (清醒梦). ___46___ Only some people are able to have them. Now, scientists have found ways to help more people to have lucid dreams, Live Science reported.
Denholm Aspy from the University of Adelaide in Australia found that certain skills are key to helping people have lucid dreams.
First, people can train themselves to figure out whether they are dreaming or not. For example, someone may look at a clock, look away, and then look back. ___47___ Then, they might dream about this trick while sleeping. But in their dreams, the time on the clock may change very quickly. So people know they are dreaming.
Another trick is to wake up after five hours of sleep. ___48___ During this time, repeat the words, “The next time I’m dreaming, I’ll remember that I’m dreaming.” Then, go to bed again to enter rapid eye movement (REM，快速眼球运动) sleep. In REM sleep, people are more likely to be aware of their dreams.
Scientists found that those who used these tricks had a 17 percent success rate at having lucid dreams. ___49___
In a lucid dream, people might study a hobby and then become better at it in real life, according to Aspy. For example, you might learn to play the piano in a lucid dream. ___50___
A. Then, stay awake for a while.
B. The time should stay the same.
C. This was far higher than if they did nothing.
D. People learn new skills faster in a lucid dream.
E. It is hard for most people to have a lucid dream.
F. Then, your real-life piano skills might improve.
G. Some people will need more time to fall asleep and have a dream.
