Unit 5 Into the unknown
Listening and speaking
Learning objectives
To listen to several conversations
To know the meanings of proverbs in the listening materials
To listen to an interview and finish some exercises
To tell a story about yourself that can be summarised by a proverb
Activity 5 Read the passage and answer the questions. Pay attention to the words and expressions in bold.
When something strange or unfamiliar happens, the flight instinct can kick in. Often, making a quick getaway is a sensible and understandable natural response, dating back to a time when our ancestors were running for their lives from dangers, such as wild animals, lightning and fire. So while you may be tempted to check out a strange object or to test the waters of a new situation, it can be safer to steer clear of the unfamiliar.
快速逃离
为了躲避危险而拼命奔跑
核实，检查
试水，试探
避开，绕开
However, not everyone chooses to follow this instinct.
Instead of retreating to their caves, some of our ancestors
chose to subdue their fears and pursue the unknown - and
this curiosity led them to, for instance, discover the use of fire.
In more recent times, Norwegian explorer, Roald Amundsen endured one of the most hostile environments on Earth when he set out into uncharted territory to reach the South Pole - a region of the planet ripe for exploration.

忍耐，忍受
打算，着手
These reactions help humankind delve into the unknown and advance towards a more progressive and civilised society. Of course, exploration doesn’t have to mean blindly throwing ourselves into the unknown, and it’s never wrong to think twice before taking action. While there is no need for us to shrink from new situations, we should always look into things first and consider our options.
