2/ CHOOSE THE CORRECT ANSWER TO COMPLETE MI'S EMAIL TO HER NEW FRIEND, ELISA

Dear Elisa,

Thanks very much for you email. It was fun to read about the places you find interesting.

I (don't like/ interested in/ also/ will) like going to museums in my free time. There are several museums in my city, but i like the Museum of Fine Arts the most. I have art, so (because/though/ that/ when) I have free time, I go to this museum. There's a great mix (in/of/on/with) art from across the eras, including some reality impressive modern Vietnamese paintings. What I especially I like about the museum is that (all/one/none/not) of its galleries have an introduction in Vietnamese, English and French. It (means/shows/proves/tells) that I can learn lots of English while enjoying the art works.

Another place of interest that I love is the (locality/ small/ area/local) park. It's near my house, so I go there almost every day. Sometimes I go for a walk around the park with my mother. Sometimes I choose a beautiful place in it to sit and draw some sketches. And sometimes I just sit (in/at/on/with) a bench, doing nothing, just watching people passing by. It's really relaxing.

I hope someday I'll have a(an) (chance/opportunity/ time/choice) to visit your National Portrait Gallery and Hyde Park.

Until the next mail,

Mi
