B. Choose the best answer and complete the passage (选择最恰当的选项完成短文)At the age of 16, Einstein always played with a group of naughty kids. He was so busy playing, so he didn't study enough and failed his final exam.
One morning, when Einstein was holding a fishing rod and was about to go fishing with his friends, his father1 him and said calmly, "Einstein, you're so fond of playing all day that you failed your exam. I'm worried about your future."
"What are you worrying about? Jack and Robert also failed, but they could 2 go fishing." "My boy, you can't think like that," his father said. "There is a story that people tell in our hometown. Listen to it now."
"There were two cats playing on a roof. But unluckily, one cat was careless and 3 the chimney while holding the other cat. When the two cats tried their best to climb out of the chimney, one cat had soot (烟灰) on the face, while the other cat's face was clean. Seeing the soot-faced cat, the clean cat thought its face must be 4 , so it ran to the riverside and washed its face. The soot-faced cat saw the clean-faced cat and thought its face was also clean, so it just walked down the street as usual. People all laughed at this cat."
"Einstein, no one can be your '5 '. Don't blindly follow others. You have to think for yourself. If you take your cue from others (照别人的样子做), you will never learn."
Hearing this, Einstein thought for a while and then laid down his fishing rod and returned to his room. He decided to pay more attention to his6 and less attention to what his friends were doing. This allowed him to be successful.
