Step 7 Watching, reading and thinking1). Class work The teacher is ding such an experiment and showing it to all the students: Prepare four glasses on the table. One is filled with oil, one vinegar, and one spirit. Pour some of the liquid into one big glass and then mix them up. Dip one finger into the mixture, take it out then and put it into the mouth to suck. Then give a smile to the students to show that it tastes very delicious. Show the glass around the class and ask the students to do everything as the teacher does. Q: Does the mixture taste good? Why do you have a different taste from mine? 2). Individual work Read the passage titled “Look carefully and Learn” to find out the reason. Q 1: What do you learn after you read such a story? Q 2: Do you think what is the most important when you are doing an experiment in the lab? Q 3: If you want to be a scientist, what do you think are the most important qualities? Homework: Read the following passage with the questions below.
Flossie Wong-Staal
An interview with Emilio Alvarez and Ann Crystal Angeles
Flossie Wong-staal stays on the move. She moved with her family from China to Hong Kong when she was five. Later she moved to the United States to attend college. Now Wong-Staal is on the move to clone the virus that is believed to cause AIDS and to figure out how the molecules（分子）of the virus are arranged. Wang-Staal heads a team of scientists at the university of California, San Diego. They are trying to save lives by making an AIDS vaccine(疫苗). Emili How did you decide that you wanted to become scientist? Wong-Staal: At first my teachers made the decision. In high school they said I should study science because of my grades. By the time I graduated from college, there were so many exciting discoveries being made in molecular biology that I wanted to specialize it. Emili What was your high school like? Wong-Staal: I went to an all-girl high school in Hong Kong. I felt very free at an all-girl school, and I have fond memories of that time. Anne Crystal: Would you explain your research? Wong- Staal: Basically me colleagues and I are trying to understand how the AIDS virus is replicated, and then to develop ways to interrupt the replication process, By “replication” I mean the way in which the virus gets inside a cell and uses that cell as a sort of factory to make many many copies of itself. Anne Crystal: Do you always enjoy your job in the laboratory? Wong-Staal: Yes,, I think it’s very exciting work. Of course it’s not every day that you make a discovery and have that kind of reward. But when it does happen, it’s a real thrill. It’s exciting to know that you brought about knowledge that didn’t exist before. Anne Crystal: What would you tell students who would like to become research scientists? Wong- Staal: Stay with your interest, and get good information about the education you will need. I also have warning: Things are not always easy. There are frustrations in research; sometimes things don’t go the way you’d hoped. But when you make a discovery or a contribution to science, it becomes worthwhile. And I want to encourage all young people to be interested in science: We need you ! 1. As you read, guess the meaning of the boldface words from the surroundings words and sentences. 2. Look back over the reading to find the following information: (1). Where Wong-Staal was born: (2). What she is studying in her research: (3). What she was the first person to d (4). This article is primarily about______________. A. the scientist Wong- Staal B. making an AIDS vaccine C. preventing the spread of disease (5). Which question is NOT answered in the reading?- What college did Wong- Staal attend B. What type of biology did she specialize in
