【文章內容簡介】 m. In 1997, they saw evidence of planets near other stars like the sun. But scientists now think that life could be even nearer in our own solar system. One place scientists are studying very closely is Europa, a moon of Jupiter. Space probes have provided evidence that Europa has a large ocean under its surface. The probes have also made scientists think that under its surface Europa has a rocky core giving off volcanic heat. Water and heat from volcanic activity are two basic conditions needed for life to form. A third is certain basic chemicals such as carbon, oxygen and nitrogen. Scientists believe there might be such chemicals lying at the bottom of Europa’s ocean. They may have already created life or may be about to. You may wonder if light is also needed for life to form. Until recently, scientists thought that light was essential. But now, places have been found on earth that are in total blackness such as caves several miles beneath the surface. And bacteria, primitive forms of life, have been seen there. So the lack of light in Europa’s subsurface ocean doesn’t automatically rule out life forming.Questions26 to 2826. What did scientists once believe according to the passage?27. What have scientists found about Europa, a moon of Jupiter?28. What have scientists e to know recently about formation of life? Passage 2In her early days as an emergency room physician, Doctor Joanna Myer treated a child who had suffered a second degree burn. After the child had been treated and was being prepared for discharge, Doctor Myer talked to the parents about how they should care for the child at home.

A few hours later, when she came to say goodbye, the family asked her to settle an argument they’d been having over exactly what advice she had given. “As I talked to them, I was amazed.” she said, ”All of them had heard the simple instructions I have given just a few hours before, but they have three or four different versions. The most basic details were unclear and confusing. I was surprised, because these were intelligent people.” This episode gave Doctor Myer her first clue to something every doctor learns sooner or later most people just don’t listen very well. Nowadays, she says she repeats her instructions, and even conducts a reality check with some patients. She asks them to tell her what they think they are supposed to do. She also provides takehome sheets which are puter printouts tailored to the patients’ situation. Doc. Myer’s listeners are not unusual. When new or difficult material is presented, almost all listeners are faced w
