Unit5: Nature's Temper Section B ( reading plus) Are you afraid of big storms? A Common Fear Many people are afraid of big storms. The loud thunder, heavy rain, and dark clouds can be very scary. Storm Chasers Did you know some people go out to chase tornadoes? They are brave people who want to observe storms. What is Storm Chasing? Tim Samaras (1957-2013) "The best way to understand a tornado is to get inside one." ① Are you afraid of big storms? Many people are. But did you know some people go out to chase tornadoes? Such storms can hit suddenly and move very quickly, so storm chasers always have to be prepared. ② When a tornado is about to hit, professional storm chasers try and get close to it to collect important information. Storm chaser Tim Samaras designed and built many different instruments for studying tornadoes. Throughout his career, the engineer chased down more than 120 tornadoes. Often, he filmed the storms while they were happening just a few kilometres away. Storm Chasing: A Dangerous but Important Job 追风(指追逐风暴、龙卷风的行为/职业) be afraid of 害怕…… 突然来袭 移动速度极快 必须做好准备 be about to do 正要做某事 chase down 追踪;追捕 专业的 仪器 在他的整个职业生涯中 他经常在距离风暴仅几公里的地方拍摄下风暴发生的全过程。 蒂姆 萨马拉斯 ③ During a storm, storm chasers put special equipment in the way of the tornado. The equipment collects information about things such as wind speed and air pressure. This helps scientists to make better forecasts. It can even help people understand how powerful the winds can be, and as a result, change how we build our houses. ④ Storm chasing can be exciting, but also very dangerous. The storm chasers' knowledge and experience are not always enough to keep them safe. On 31 May 2013, Samaras and his team were chasing the El Reno tornado in Oklahoma, USA. To their surprise, the tornado behaved in an unexpected way. It grew rapidly and changed its speed and direction. 把……放在……的行进路径上 风速 气压 做出更精准的预报 甚至能让人们了解风的威力究竟有多大, 因此 改变我们建造房屋的方式 既刺激又危险 =not only...but also... keep sb. safe 保护某人安全 萨马拉斯和他的团队正在追踪美国俄克拉荷马州的埃尔里诺龙卷风。 表现 改变速度和方向 in a ... way 以……的方式 ⑤ On that terrible day, the largest tornado ever recorded appeared. It was 4.2 kilometres wide and had winds topping 480 kilometres per hour. While the tornado was moving towards them, Samaras and his team were driving as fast as they could. Sadly, when the tornado hit their car, it threw their car into the air like a toy. All three men in the car died. ⑥ The story of Tim Samaras is very sad, but his work continues to play an important role in weather science. Though storm chasing remains a dangerous job, the goal of storm chasers is to learn more about storms to keep people safe. For people like Samaras, that goal makes it all worth it. 在……中发挥重要作用 让这一切都值得 有记录以来最大的龙卷风出现了。 有记录以来的 move towards-向……移动 像玩具一样把……抛向空中 气象科学 仍然是、保持 的目标 Why is Storm Chasing Important?

How One Girl Saved Many Lives On 26 December 2004, Tilly Smith, a 10-year-old English schoolgirl, and her family were on holiday in Phuket, Thailand. Everyone was enjoying the beautiful weather that morning. Some people were swimming in the sea, and some were relaxing on the beach. But while Tilly was walking along the beach with her family, she noticed something strange. Thick white froth was forming on top of the waves. Next, she saw that the waves were coming in instead of going out. Just then, she remembered something important. Two weeks before, her geography teacher had explained that earthquakes under the sea could create dangerous waves called tsunamis! “I know what’s going to happen! There’s going to be a big wave,” Tilly cried. Unfortunately, her family didn’t believe her and wanted to continue their walk. However, Tilly refused to take a single step further. Finally, her mother decided to continue the walk alone, and the rest of her family returned to the hotel. 度假 泡;泡沫 refuse to do sth 拒绝做某事 take a step 迈步 decide to do sth 决定做某事 剩余的……; 其余的…… Language points However, Tilly refused to take a single step further. 然而,蒂莉拒绝向前迈出一步。 refuse sb. /sth. 拒绝某人/某物 refuse to do sth.拒绝做某事 Jenny refused/turned down my help politely. 珍妮礼貌地拒绝了我的帮助。 We should obey the law and refuse to waste food. 我们应该遵守法律,拒绝浪费食物。 refuse v.拒绝;推却 与accept互为反义词。 While-reading 1b 1.

The security guard was shocked. He knew about the huge earthquake in nearby Indonesia. It meant that a tsunami was possible! He jumped into action right away and rushed to get people off the beach. Everyone began to panic. People were screaming and running as fast as they could when they saw a huge wall of water coming from the sea. Tilly was right! Her mother was one of the last people on the beach, but thankfully, her family made it to safety just as the water hit the hotel. The 2004 tsunami caused over 200,000 deaths, but no one on the beach died that day. This true story shows how a single lesson could mean the difference between life and death.
