We knew that Amy went to Beijing Zoo. Now Daniel is asking her about the visit to the zoo.

You can see four sentences here.

The dolphin show was long.    We must protect wild animals.

Wild animals are our friends.   I stayed in the zoo for so much time.

We must protect wild animals because wild animals are our friends.

I stayed in the zoo for so much time because the dolphin show was long. 

Step 2 Practice

Open your books, turn to page 67. Use ‘because’ to help Amy answer Daniel’s questions. Let’s check the answer.

Amy saw a dolphin show in the zoo. Now she is talking about it. Turn to page 67,

Please work out what she is saying by making sentences using ‘because of’. Let’s check the answer.

We can use ‘because’ to give the reason(s) for something. The word ‘because’ introduces the clause of reason and we usually put it in the middle of a sentence.          

我们可以用 ‘because’ 来引导原因状语从句，一般放在句子的中间。

e.g.

We can also use ‘because of’ to give the reason(s) for something. We use a noun, a noun phrase or a pronoun after ‘because of’.

我们也可以用 ‘because of ’ 来表示原因，后面跟一个名词短语或代词。

e.g.
