In English, expressing future plans, intentions, and arranged activities is commonly structured using the 'be going to' formula. This grammatical structure is highly prominent when discussing school holidays, half-term breaks, and family trips. For example, when Ms Stark discusses the family's half-term holiday plans, she uses 'We are going to visit an amazing continent' and 'We are going to ride a camel there'. This indicates that the decisions have already been made and planned prior to the moment of speaking.
The structure of 'be going to' consists of the subject, the auxiliary verb 'to be' (am, is, are) conjugated according to the subject, followed by 'going to' and the base form of the main verb. For instance, 'I am going to go skiing' or 'He is going to ride a bike'. In negative sentences, 'not' is placed right after the auxiliary verb 'to be', as in 'We are not going to stay in a tent'. For questions, the auxiliary verb is moved to the beginning of the sentence, such as 'What are you going to do for your holiday?' or 'Where are they going to do the activities?'.
Additionally, the modal verb 'will' can be used to express spontaneous decisions, predictions, or promises about the future, often accompanied by expressions of certainty like 'definitely'. In the family dialogue, Ms Stark says, 'We will enjoy the view when the Sun rises,' and Arnold writes in his postcard from Italy, 'Later, I will be at the Trevi Fountain. I will make a wish and toss a coin.' This shows a blend of planned events ('be going to') and predictions or immediate intentions ('will') during travel.
The theme explores several unique geographical and natural wonders across the globe, providing students with rich descriptive contexts. Lençóis Maranhenses is a spectacular desert and national park located in Brazil. It is famous for its unique appearance, resembling a giant beach with white sand dunes. During the rainy season, rainwater fills the spaces between the sand dunes, creating crystal-clear blue lakes where tourists can swim, enjoy the view, and take photos.
The Grand Canyon, located in the state of Arizona, USA, is another massive natural landmark highlighted in the text. It is a colossal canyon over 270 miles long, about 18 miles wide, and over 1 mile deep, with the Colorado River flowing directly through it. This national park is home to diverse wildlife such as deer, mountain lions, and various bird species. Tourists visit the Grand Canyon primarily to hike, enjoy the breathtaking views, and take photographs.
The Great Barrier Reef, situated off the coast of Australia, is the largest reef system on Earth, consisting of 2,900 individual reefs and 900 islands. It is so immense that it can be seen from outer space. The reef is a vibrant marine habitat home to colourful fish, sea turtles, dolphins, and sharks. It is a premier destination for water activities like snorkelling and scuba diving, where visitors can observe the crystal-clear water and colourful coral.
The unit introduces the format of postcards as a medium of travel communication, showcasing Arnold's journeys through Finland, Italy, and England. In Finland, Arnold experiences the winter season, plans to watch the magical Northern Lights in the sky, and visits a unique museum constructed entirely of real ice. This highlights how climate and seasonal activities shape holiday plans and travel experiences.
In Italy, Arnold focuses on a historical sightseeing tour under sunny weather. He visits the Colosseum and plans to go to the Trevi Fountain to toss a coin and make a wish to travel the world. This illustrates the cultural and historical aspects of tourism, where specific landmarks are associated with local traditions and bucket-list experiences.
In England, Arnold explores London, describing it as a dream destination with a historic vibe despite the low temperatures. He enjoys the view of the city from the London Eye, plans to visit Tower Bridge, and intends to relax at Hyde Park. This section emphasizes urban tourism, sightseeing tours, and the appreciation of historical cityscapes.
