第三部分: 概括段落大意和补全句子（每题1分,共10分）My Science Teacher?Usually whenpeople decide to be teachers, they go to college, get a degree, and find a job at a school. They prepare lesson plans, give out homework, and make up tests. To them,it is just a job, a way to make a living. But for my science teacher, Mrs. Cook, teaching is not just her job; it's who she is. She teaches through her heart.?She has so much enthusiasm in her lessons. She is the one who goes out late at night tobuy 10 pounds of sugar for our experiments. She brings inwater from the nearby canal to make her point, and to make us remember the lesson. She makes usthink that each new fact could change our lives.?Mrs. Cook wants all of us to do well in school. She tries to reach each student. Sheneither ignores the sleeping kid in the back, nor lets the problem students alone. She shows special concern to slow students, and often helps them after school. None of us can slip away from her attention.?Middle school is probably one of the hardest times of our lives. We change friends so often, and fight with our parents constantly.But Mrs. Cook has made thisyear So much better for us than it could have been. We know that if we had to turn toanybody, it wouldbe her. And I'm not alone in feeling this way; she is arole model for our whole class.?Science had never been my favorite subject. I had never borrowed science books. I had never performed experiments in my home.But this year, it's the science class that I don't mind waking up for, the testI don't mind taking. I have Mrs. Cook to thank for that. She has taught us so much more than just a single subject.
