Presentation 1.7.2013 ‹#› Lead-in Presentation Answer the questions Q1: What does "it" refer to in sentences (a) and (c)? It does not refer to anything. It is an empty subject standing for the real subject at the end of the sentence — "not to take any chances" in (a) and "to remember that Ebola doesn't respect national boundaries" in (c). 1.7.2013 ‹#› Lead-in Presentation Answer the questions Q2: What is the difference between the sentences in each group? Why does the author choose (a) and (c) instead of (b) and (d)? In (a) and (c), the real subject is moved to the end and "it" is used as an empty subject; in (b) and (d), the real subject comes first. The author uses (a) and (c) because the real subject is too long; putting "it" at the beginning keeps the sentence balanced and makes it more natural to read. 1.7.2013 ‹#› Presentation Discover the rule Type Structure Example Type 1 infinitive It is + adj.

MSF, or Médecins Sans Frontières, is a world-famous medical charity devoted to global public health. It is well-known that MSF offers free medical treatment to people in war-stricken or disaster-hit areas. It is obvious that diseases never respect national boundaries. With frequent global communication and travel, infectious diseases can spread rapidly across countries. As a result, no nation can defeat epidemics independently. Therefore, MSF’s work is of great importance to the whole world. I hope you can learn more about it and develop a sense of social responsibility.

Such cultural integration enriches the city’s lifestyle and atmosphere. In short, cultural diversity is the most precious feature of Shanghai. It is exactly this feature that makes the city unique and charming. 1.7.2013 ‹#› Thank you for your listening 1.7.2013 ‹#› $
