Both show people doing physically challenging activities in extreme conditions. In photo A, the people are walking in a desert in extreme heat. They are lightly dressed and carrying rucksacks. If they aren’t careful, they could become dehydrated and even die. In photo B, there is a climber sitting outside a tent in the mountains. He’s wearing an oxygen mask to help him breathe at this high altitude.

- How to pronounce numbers?
When we say numbers with decimals, we use point, e.g. 3.5 is three point five. When we say years, we treat the first two digits as a separate number, e.g. 2015 is twenty fifteen. When we say ratios, we use to, e.g. 20:2 is twenty to two. When we talk about a range, we can say between … and … or … to … Therefore, 5–10 is five to ten or between five and ten. Zero can be pronounced as nought/naught /nɔːt/.

There are many amazing stories of human survival, but actually our bodies are very fragile and do not cope well with extremes. Polar explorers can cope with temperatures of (1) ______, but only if they keep warm. Most people will collapse if their body temperature drops by only (2) ______, and if it drops by (3) ______, they'll die. Heat can be just as dangerous. Temperatures of 35°C are safe, provided humidity is not above (4) ______. High altitudes are dangerous too. We pass out when the pressure falls below (5) ______  of normal atmospheric pressure. This happens at about (6) ______   metres. Climbers can go higher because their bodies gradually get used to it, but no one survives for long at 8,000 metres. At high altitudes, lack of oxygen is another problem. At ground level, about (7) _____ of the air is oxygen. If that falls below (8) ______ , we die.

There are many amazing stories of human survival, but actually our bodies are very fragile and do not cope well with extremes. Polar explorers can cope with temperatures of (1) ||–40°C|| , but only if they keep warm. Most people will collapse if their body temperature drops by only (2) ||5°C||, and if it drops by (3) ||15°C||, they'll die. Heat can be just as dangerous. Temperatures of 35°C are safe, provided humidity is not above (4) ||50%||. High altitudes are dangerous too. We pass out when the pressure falls below (5) ||57%|| of normal atmospheric pressure. This happens at about (6) ||4,500|| metres. Climbers can go higher because their bodies gradually get used to it, but no one survives for long at 8,000 metres. At high altitudes, lack of oxygen is another problem. At ground level, about (7) ||1/5|| of the air is oxygen. If that falls below (8)||1/10|| , we die.

7. SPEAKING Discuss the questions in pairs
A: Have you ever been awake all night or most of the night? If so, when/where/why? B: Yes, I have. I remembered when I was in grade 9, I usually stayed up late until 2.00 to 3.00 A.M. to do my homework as well as prepare for my big examination to enter high school. It was really tiring and stressful. A: Have you ever felt very cold? If so, when/where/why? B: Yes, I have. That is when I went to Da Lat last year. Because I live in Ho Chi Minh city, I get used to hot weather. Therefore, when I came to Da Lat, the weather was so low, just about 15 degrees Celsius. I felt extremely cold. A: Have you ever experienced high altitude? B: No, I haven't. You know I'm a kind person who is very scared of heights. I also don't have any intention to try it one time in the future.
