My invention __________________ One fact and its source ______________________________
Read a writer’s plan 拆解范文结构
Read 3a. Complete the chart using short notes. Draw a line between each flight challenge and the part of the solution that helped.
Paragraph 段落 | Question the reader asks 读者想知道什么 | Notes from 3a 范文信息 |
1 | What was invented? Who were the inventors? What did they want to do? | |
2 | What two challenges did they face? How did they solve them? When were the first flights made? | |
3 | What changed for travellers and people in different countries? | |
A reason and a result 区分初衷与影响
A writer puts “They wanted to make travel faster across the world” in paragraph 1. Does 3a support that as the brothers’ aim? Move the idea to the right part of the plan, then write a better sentence about the original aim.

Find facts that belong together 让事实串成解释
Check your notes for 3b 为3b核对资料
Use your source or choose one from the textbook. Record where the details come from. Distinguish a date when an idea was developed from a date when it was shown or tested.
Note to collect 资料项目 | What I can support 能确认的事实 | Source 来源 |
Name, inventor and date or event | | |
Need or aim | | |
Material, if the source states it | | |
One challenge and a response | | |
One change in people’s lives | | |
Write check if a fact still needs a source. You can leave it out of your draft. The text on p. 44, for example, gives dates for the radio but does not tell us what the first set was made of.
Build one link at a time 搭好两段因果
Choose one problem and one action that answers it. Then choose one effect you can explain by comparing life before and after the invention.
