(二)热身(Warming up)
本单元的话题是“绿色世界”,主要谈论的是植物学这一学科。学生对这一话题并不陌生,但是也不会懂得很多。建议教学活动如下:
1.T:What is the green world? What can we e in the green World?
Ss:We can e a lot of trees,plants,flowers, vegetables and etc.
2.How many trees do you know? 教师向学生展示有关树的图片。
How many flowers do you know? Can you name some?(Ss can name the flowers in Chine if they don’t know the English for the flowers.)教师向学生展示有关花的图片,并逐个讨论。
如:
What is the name of the flower?
Where does it usually grow?
showers
What is it ud for?polytron
Does it have any special meaning? What is it?
Can you describe it?
What is your favourite flower? Why?
教师和学生一起讨论有关花卉知识,并呈现有关花卉的词汇。然后完成课本练习。
(注意:下列材料仅供参考:)
Flowers come in many different colours,shapes and sizes.Flowers like tulips and ros are big and showy,but grass and oak tree flowers are tiny and often difficult to e.Flowers grow on garden plants,on shrubs,on trees and even on grass.They contain the parts that make eds.The eds will grow into new plants.So flowers help to make more plants of the same kind.
Blossoms Many trees have attractive colourful flowers,or blossoms.The blossoms of fruit trees,such as cherry,apple and pear, develop into fruits,which contain the trees’eds.
Colour and scent Some flowers,like poppies,are brightly coloured. Hyacinths and ros are colourful and have a sweet smell,Flowers which bloom early in the year, such as snowdrops and daffodils,are mostly white or yellow.Sunflowers are always yellow in colour, but other flowers,like chrysanthemums,can be yellow. orange,blue,red,and many other colours,too.
Hidden flowers The flowers of grass and dge plants can be difficult to e.They are often the same colour as the plants,leaves and steins Some trees,such as willow and poplar trees,grow plain-looking flowers called catkins They hang down from the tree in small clusters
(三)听力(Listening)
热身活动之后,相信学生对花卉有了初步的了解。听力的内容是有关“水果”的话题,因此,教学活动可以紧接着进行。建议教学开展“听前”、“听录音”和“听后”活动。
1.听前活动:师生讨论
ml是什么的意思
T:Now you have some knowledge of flowers The green world includes flowers,vegetables and fruits.Do you like fruits? What do you know about them? What kinds of fruit do you know? (教师可以出示各种水果图片,学生讨论水果有关知识)
学生小组讨论:
1)names of the fruits;
2)kinds of the fruits;
3)ways to put different kinds of fruit into groups;
4) why people need to eat fruit.

2.听录音,完成第4、5练习。
3.听后活动:学生根据听前讨论内容和录音材料,谈谈水果方面的有关内容,也可以作为课后书面作业,写在作业本上。

建议教学开展以下活动:
1.师生讨论:

What is it?
Who usually looks after it?
