Reading strategy:
understanding scientific terms(科学术语)
When reading articles about science,
we often come across difficult scientific terms.
We have to work out their meanings in order to understand the text as a whole. Begin by reading the first and last paragraphs for an idea of what the article is about.
Then, scan the body of the article. Circle any words you do not know. Question things that you do not understand or that do not appear to make sense.
Finally, read through the article a few times. You will often be amazed to discover that what confused you at first makes sense upon further readings.
