[06:57.59]Grade EightA trip to AfricaHi!
[07:06.06]I'm Irfan.I'm the guy who likes social studies and travelling!
[07:12.22]Last summer,I went to Africa with my family.We went for three-and-a-half weeks.
[07:19.88]Why did we go?Because my mum and dad come from east Africa.
[07:26.43]They wanted to see it again.
[07:29.88]They also wanted to show Africa to my sister and me.
[07:35.24]We went to a special park in east Africa called Masia Mara.
[07:41.11]The park has many wild animals.We saw lions,elephants,
[07:47.77]giraffes,zebras,cheetahs and many other animals.
[07:54.25]We were going to camp in the park,but it was too scary.
[07:59.40]There were too many wild animals.
[08:03.24]So we stayed in a hotel and drove to the park every day.
[08:08.80]One day,we went to a village.It was interesting,
[08:14.37]but the people were very poor.I don't think they were very healthy.
[08:20.01]Was the food in Africa different?Not really.
[08:25.18]We had lots of food I knew from home, like rice and meat.In some hotels,
[08:32.31]we had a North America breakfast,but in other hotels,we had Indian food.
[08:39.16]I like Indian food--my mother cooks it all the time.
[08:44.41]Would I go to Africa again?Yes!I would love to go back.
[08:51.25]It was a good holiday because I learned a lot.
[08:55.80]I didn't just sit on the beach!Jenny:A guy is a boy or a man.
