Breaking boundaries
Look at the sentences and answer the questions. Sentences (a) and (c) are from the reading passage.
1 What does “it” refer to in sentences (a) and (c)
2 Why does the author choose to use sentences (a) and (c) instead of (b) and (d)
a But it is vital not to take any chances.
b But not to take any chances is vital.
c It is important to remember that Ebola doesn’t respect national boundaries.
d To remember that Ebola doesn’t respect national boundaries is important.
The first sentences in each group use “it” as an empty subject at the beginning of the sentences. The reason why sentences (a) and (c) are chosen is that the sentences are kept balanced and the key information of the sentences is emphasised.
Now look for more sentences with this structure in the reading passage, and summarise its use in your own words.
I felt it was my duty as a doctor to go there and offer my help.
It is so inspiring to have colleagues like Wilton, Maisy and Alfonso, ...
..., it is absolutely essential for us all to collaborate to create a global community with a shared future of peace and prosperity.

The global village
Read the passage and answer the questions. Pay attention to the expressions in bold.
①What phenomenon does the passage describe
②What effect does technology have on cultural exchange
Dear Editor,
Your article about living in a global village really struck a chord with me because I've just returned from a teaching project in Cambodia and Thailand. I had been worried about the 1 , but fortunately the other volunteers and local teachers were really welcoming. We were able to 2 each other as well as our students. Throughout, we made 3 to make our classes a success, so that we could all enjoy the 4 of working well together. It was rewarding to see how our work helped 5 from different cultures. Before I went, TV and the Internet were my 6 ,but being there in person was even better. I think the experience has taught me to7 and I can't wait to do it all over again.
