The significance of these breakthroughs
Para 1
Para 2-6
Para 7
Read the article again and answer the following questions.
TASK 4
1. Which discovery or invention mentioned in the text has been the most important so far Why
Example 1: I think the invention of World Wide Web has been the most important so far, because it is of great practical significance for most people. Life without it is unimaginable.
1. Which discovery or invention mentioned in the text has been the most important so far Why
Example 2: 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.
2. Which discovery or invention will most influence the future Why
Example 1: I think E=mc will most influence the future. Because with the decreases in natural resources, energy problem has become more serious than ever. E=mc provides theoretical basis for future research.
2. Which discovery or invention will most influence the future Why
Example 2: 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.
Line 12: Although... Here are some of them.
Line 15: One of the 20th century's premier scientists was...
Line 24: ...another important finding...
Line 34: ...when Fleming's discovery was...
