PLANT MORPHOLOGY
TASK A. Identification of plant structures and organs from images shown in a PowerPoint presentation (16 marks)
根据投影片显示的影像来鉴定植物的构造及器官(16分)
In this task, you are required to answer the following questions, each of which relates to a slide that you will be shown. Each slide will be shown twice.
在A部分,你须回答下列问题,每题都会显示一张投影片,并且会放映两次.
In the first showing, each slide will be displayed for 45 seconds, then the second slide will be shown for 45 seconds and so on until all 16 slides have been once.
第一次放映时,每张投影片放映45秒,接著是第二张投影片,同样放映45秒,直至16张全部放映完毕.
The second showing is to give you the opportunity to review your answers. In this showing, each slide will be displayed for 15 seconds.
第二次放映乃供你检查答案,但每张投影片仅放映15秒.
