阅读理解     Back in 2008, American photographer Rose-Lynn Fisher was going through a hard time in her life, so she often cried. One day, she didn't brush her tears(眼泪)away. She put one tear under a microscope (显微镜), wondering what her tear would look like.     She was amazed by what she saw. "It was really interesting, "she told the Telegraph. "It was almost as if I was looking down at a landscape from a plane. "It was such an amazing discovery!     So she started thinking about a question: would a tear of grief(悲伤)look any different than a tear of joy? What about a tear from cutting an onion?     She collected 100 samples(样本)of tears caused by different things and put them all under a microscope. She was surprised to find that their appearance was changed by what had made people cry.     She thinks that this might be because of the different hormones(荷尔蒙)in the tears. The hormones may change their molecular（分子的）structures.     Then she wanted to know if men's tears are different from women's tears. She was also surprised by what showed up in the photographs of microscopic tears.     It was not a controlled scientific study, so there were many factors that could influence the resulting images. However, what she found was already something impressive.     Why don't you save some of your own tears and see what they look like when you are sad, happy or chopping(切) onions? （1） Why did Fisher cry often in 2008? A . Because she was having a hard time. B . Because she needed tears to do her research. C . Because she dropped a microscope. D . Because she was not good-looking. （2） Fisher was amazed by _______________. A . difficulties in her life B . a tear under a microscope C . a beautiful landscape D . her trip on the plane （3） What does Paragraph4 talk about? A . How many tears she had cried. B .
