GATEWAY 3 WEBSITE Extended Writing Worksheet 8 Genre Describing a natural process Title The king of fruit Topical content Growing durian trees Language focus Expanding notes into sentences Time expressions and sequencing Specific objectives The students write sentences from notes, using the correct verb forms. The students use a range of time expressions to show varying lengths of time. The students write a 150-word description of the life cycle of durian trees. Activity types Sentence construction Substitution Extended writing: drafting and checking Notes 1 Explain the writing objective before the students begin the preparatory activities. 2 The students can revise much of the vocabulary by referring to the section on plant reproduction in their Science text book. They can also check for the appropriate time expressions to be used in Activity B, if required.

Write at least 150 words. Developing notes Amir has to research the life cycle of plants for a science project. He has chosen his favourite fruit, the durian. Read Amir’s notes below and write the information in complete sentences. 1 durian = King of Fruit 2 trees native to SE Asia, esp. Malaysia, Indonesia, Brunei 3 ripe fruit up to 30cm long; unique odour; spiny skin 4 food source: monkeys, birds, squirrels, elephants, tigers B Time expressions During his research, Amir discovered that the different stages of plant reproduction take different lengths of time. He wrote some sentences to show the major stages of the life cycle of the durian tree. Make each sentence more accurate by replacing the underlined words with one of the time expressions below. in three to eight days immediately when they are five to seven years old First, wind, animals or insects pollinate the flowers.

The trees are native to South East Asia, especially Malaysia, Indonesia and Brunei. The ripe fruit is up to 30 cm long. It has a unique odour and a spiny skin. Durians are a food source for monkeys, birds, squirrels, elephants and even tigers. First, wind, animals or insects pollinate the flowers. Then the pollen tube forms. Then the zygote divides and becomes an embryo. Then the fruit starts to grow. Then the fruit is ripe. Animals, wind or water disperse the seeds. Then the seeds germinate. Then the plants mature and flowers develop. 1 First, wind, animals or insects pollinate the flowers. 2 After about two hours the pollen tube forms. 3 Immediately, the zygote divides and becomes an embryo. 4 Four weeks after pollination the fruit starts to grow. 5 Twelve to sixteen weeks later, the fruit is ripe. 6 In three to eight days the seeds germinate. 7 When they are five to seven years old the plants mature and flowers develop. Sample answer The King of Fruit The durian is so popular that it is known as the King of Fruit. The trees are native to South East Asia, especially Malaysia, Indonesia and Brunei. The first stage in their life cycle is pollination. Bats and moths are the agents of pollination. They cross-pollinate the flowers when they drink the nectar. After about two hours, a pollen tube develops. In the fertilisation stage, the male cell moves down the pollen tube to the female cell, located in the ovule. A zygote forms. Immediately, the zygote divides and develops into an embryo. The ovules develop into seeds while the ovary becomes the fruit. Four weeks after pollination, the flesh of the fruit starts to form. Twelve to sixteen weeks later the fruit is ripe and drops off the tree. Different kinds of animals such as monkeys and squirrels eat the durians and disperse the seeds. In three to eight days, the seeds germinate. Roots and leaves develop. Durian trees mature in five to seven years, growing to a height of up to 50 metres. Flowers bloom in clusters from December to February. It takes about one month for the flowers to develop, ready for the cycle to begin again. 198 words E xte nde d Wr iti ng G a t e wa y t o E n g lis h 3 Copyright text C The Curriculum Development Department, Ministry of Education, Brunei Darussalam and Macmillan Publishers Limited 2008, Copyright design and illustration C Macmillan Publishers Limited 2008 PHOTOCOPIABLE Can be downloaded from website
