Last summer, Jeff became a middle school

问题：

Last summer, Jeff became a middle school student. He was a good student, and he always worked hard. He had a test in the first month and he finished the questions easily until he read the last one:”小题1: What’s her name?”

Of course, this question was a little special.   小题2:She was tall and her hair was dark. But Jeff didn’t talk with her and didn’t know her name. The test was over.   小题3: Then a student asked the teacher, “Is the last question very important in this test?”

“Yes,” said the teacher. “In our life, we will meet many hard-working people. They are important.  小题4: We may smile at them or say hello to them. 

 小题5: He also learned that woman’s name later. It was Kathy.
