Read and Explore Think and Share 1. Which discovery or invention mentioned in the text has been the most important so far? 2. Which discovery or invention will most influence the future? Why? 3. How did the writer connect the paragraphs? Underline the signal words or phrases. I think penicillin has been the most important discovery so far because it has saved millions of lives around the world. For example, in WWII, many soldiers got wounded. Penicillin was useful in keeping wounds from getting infected and helping to speed the healing process of those wounds that did become infected. Think and Share 1. Which discovery or invention mentioned in the text has been the most important so far? In my opinion, the Internet will most influence the future. Without Internet, we might not immediately have access to the latest news or materials. For example, in the educational field, people share lessons and other educational resources on the Internet, which makes it possible for students in remote areas to get educated, and promotes fair education as well.
