Facing the unknown
Read the passage and answer the questions. Pay attention to the words and expressions in bold.
Facing the unknown
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.
迅速逃走
避开，绕开
Facing the unknown
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.
撤退到
征服
Facing the unknown
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.
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.

Facing the unknown
1. What is the flight instinct Why do some people
react that way in the face of the unknown
Flight instinct is our instinctive reaction to get away from a strange, unfamiliar or dangerous situation. Some people react that way in the face of the unknown because it is a sensible and understandable natural response.

Listening & speaking
Read the passage and answer the questions.
Listening & speaking
Of all the workings of the human body, there is one organ that produces the most intrigue amongst scientists. The brain is the centre of the nervous system and controls most of the body’s activities. Interestingly, it is the back part of the brain that is involved with our vision. The sides of the brain are involved in memory, speech and rhythm.
激起……的兴趣；引发……的兴趣
节奏；韵律
Read the passage and answer the questions.
Listening & speaking
Although the brain amounts to only about 2% of total body weight, it uses up to 20% of the body’s energy — more than any other organ. Scientists have been conducting research in order to seek greater understanding of the brain, especially since the 1950s. Nevertheless, there is still a long way to go before we can completely understand the workings of this complex organ.
