I am answering a verb tense exercise when I came across this:
- I am currently travelling with Liam, a student from Leeds University in England. He is a nice guy, but impatient. He always walks ahead of me and complains that I am too slow. I (do/ am doing) my best to keep up with him, but he is younger and stronger than I am. Maybe, I am just feeling sorry for myself because I am getting old.
According to the site, the correct answer is "am doing". Please further explain why it is the answer and why "do" isn't.
Another question was this:
- Right now, Liam is sitting with the owner of the inn. They are discussing the differences between life in England and life in Nepal. I do not know the real name of the owner, but everybody just calls him Tam. Tam speaks English very well and he (tries/is trying) to teach Liam some words in Nepali. Every time Tam says a new word, Liam tries to repeat it. Unfortunately, Liam also seems to have difficulty learning foreign languages. I just hope we don't get lost and have to ask for directions.
According to the site, the correct answer is "is trying". Please further explain why it is the answer and why "tries" isn't.
