还有(háiyǒu) and 还是(háishì)

We talked about 还有(háiyǒu)  in the previous blog. 还有 is similar to "in addition" in English, which can be used with a comma and put before the verb phrase or sentence: 还有, + verb phrase/sentence. 
However, 还是 (háishì) is used in Chinese to provide options in a question. This is equivalent to one use of "or" in English:  Option A + 还是 + Option B ? For example:

• 您要喝点儿什么？茶还是咖啡？What do you want to drink? Tea or coffee? 
• 您要一个还是两个？Do you want one or two?
• 你要哪个？红色的还是蓝色的？Which one do you want? Red one or blue one?

You can even add a subject and a verb before the structure above: Subject + Verb + Option A + 还是 + Option B ?

• 你是中国人还是日本人？Are you Chinese or Japanese?
• 你说普通话还是广东话？Do you speak Mandarin Chinese or Cantonese?
• 你喜欢男孩还是女孩？Do you like boys or girls?

Please filling the blanks by using 还有 or 还是：

1. 你喜欢苹果___________香蕉？

2. 他会说普通话___________上海话。

3. 我想学西班牙语___________德语。

4. 他说的是法语___________德语？

5. 大卫是美国人___________英国人？
