Americans love sports . But this hobby sometimes has serious results—at least to the players. For example, when people play tennis, sometimes they hurt their elbow（肘部）. Also it is easy to hurt a knee in a football game. These injuries（毁伤）happen while the player is having fun, but they still hurt.
A few months ago, Kathleen Simmons, who loves playing volleyball, hurt her knee in a volleyball game. Her doctor told her that she needed a very difficult operation（手术）or she might not be able to play again. She felt very sad
Then Simmons learned about “video operation”. With the help of this new science in medicine, doctors can now repair many injuries.
For this operation, her doctor didn’t have to open her knee. Instead he put a very small camera lens（镜头）inside her knee. The lens sent back pictures, which appeared on a television screen. As he worked, he could see the inside of her knee on the TV. With the help of the large pictures on the screen, the doctor knew exactly what to do when he was making the repairs.
Simmons started walking five days after her operation. “My knee hurt a lot the first few days,” she said. “But I felt better very quickly.” Now, six months after her operation, Simmons can do everything she did before her injury. “It feels like a new knee,” she said. “I can even play volleyball again.”

(答案→)Yes. /Yes, they do. 解析：【小题1】先看问题Do Americans love sports?-----先不管原文，这是个 一般疑问句 ‘ 美国人喜欢运动吗’，回答只有一个单词，Yes/No. 这样就对了，完全没问题，没有必要再写上Yes, they do，当然你这样写也对，但这样你要再找主语指的是谁，用什么代词替代，等等，会增加你出错的概率。定位在文章开头，第一句话：Americans love sports。所以回答是Yes.【小题2】问题What sport is Simmons interested in?回原文看，哪里提到Simmons？，快速浏览，在第二段，Kathleen Simmons, who loves playing volleyball。答案就有了！就是Volleyball. 就可以了！相当于我们平日里交谈“你喜欢什么运动啊？---“排球”，，这样就可以了。【小题3】 问题是What did the doctor put inside Simmons’ knee?回原文，第四段，her doctor didn’t have to open her knee. Instead he put a very small camera lens (镜头) inside her knee.答案就有了，是 A （very）camera lens。【小题4】问题是 What problem may people have when they play sports?在文章第一段就提，····hurt their elbow·····，，····hurt a knee····，等等，可以概括，运动容易受伤嘛。所以答案是They may get hurt。相同意思都可以。【小题5】根据文章最后一段可以找出问题的答案。Simmons can do everything she did before her injury。可知回答Yes, she can.

就是这个解释
