Answer 2

Answer:

I want a boat which can take me to the island.

We have been living in Australia for six months.

Explanation:

In the first sentence we used 'a' as an indefinite article. Articles are determiners a, an, the. A/an are indefinite articles. The is definite article. The is used for those things and persons which we are already aware about. A/an is used for those things or persons that have been mentioned for the first time.

In the second sentence we used Present Perfect Continuous Tense. We use the present perfect continuous for an action over a period of time leading up to specific time. We also use 'for' and 'since' with the stated time period or duration.  

The verb form for this tense is:

has/have+been+V1+-ing
