Ben: There's one thing that you should do after school, it is
going in for sport. Sport is not only enjoyable, but useful,
because it makes you healthy. I'm mad about climbing and
I spend every spare minute at the local climbing centre.* It's
a change from school. I took up climbing about 6 months ago
and I was thrilled about it. The great thing about climbing
is that you can become good at climbing quickly. It's chal-
lenging and it makes me feel really strong. Besides, I've
made lots of friends at the centre and I really enjoy it.

Travel destinations
Read the text about three holiday destinations. Answer the questions that follow.

The best holiday destination for me is Africa. I am so excited about this continent and all its wildlife. I am a fan of wild cats like lions and cheetahs. We are going to Tanzania this summer, so I would like to go on an African safari. We didn’t book the hotel, so we are staying in a guest house. I think staying with local people is the best way to learn about their culture. (Ray)

The holiday destination which I like most is wild nature. I like staying one to one with nature, so this summer we are visiting the Marrakech desert for three days. I am so excited to ride camels and see the most wonderful sunset in the desert. It is not safe there, so we are going with a group of people. We will stay in a desert camp. We will not take a lot of clothes, only the most important things like water, warm clothes, and a map. (May)

I like learning new cultures and traditions, so we are going to have a cultural holiday in India. I like colourful celebrations outside, so this time we are taking part in the Happy Holi. It is a popular Hindu festival. It is also known as a “festival of spring” because they celebrate the end of winter and the start of spring. On Holi, people spray colours on each other, dance, and laugh. (Key)
