Step ⅣLanguage points
A. the other day = a few days ago
B. So are the fish; the fish are small, too.
C. They don’t get enough air: with a bowl, only a small surface area of the water is in contact with the air. So the water does not receive any oxygen.
D.30 cm by 30 cm by 50 cm:
We describe two - dimensional and three - dimensional measurements using the word by. So the length of the tank is 50 cm, and the width and height both 30 cm.
E. underwater plants: These plants oxygenate the water and keep it clear.
F. for one thing = one reason (for putting plants in the tank)
Step V Practice
Page 67. Part 2. Write the question on the Bb:
What should I do to keep a dog / a cat, etc.?
Ask the Students to choose a specific kind of animal, and offer their suggestions by using the following expressions:
I suggest (that) …
You should …
You ought to…
You need to…
First the teacher practises the dialogue with a good student as an example. Then the class do it in pairs. Get 2 pairs of students to come to the front and demonstrate their dialogues.
Do similar practice using the words and phrases in part 2. This time get the students to change roles.

Step II Warming-up
The teacher may ask the questions:
How many animals do you know? Give out their names.
…Dog, cat, tiger, lion, pig, rat, rabbit, cow, elephant, crocodile, monkey, ape, kangaroo, wolf, parrot, …
What animals are dangerous? How dangerous are they?
Present a diagram on the Bb to help the students:
NOT DANGEROUS VERY DANGEROUS
1 2 3 4 5 6 7 8 9 10
Ask the students to put the names in the right order to show how dangerous the animal is. For example, a parrot might be 2 on the scale, for it can bite your finger. Then put the students into groups of four to carry out the task. The teacher goes around and helps them with spelling if necessary. Get one student from each group to report their discussion. Collect some names of animals on the Bb.
