When my high school offered an all-year program，I jumped at the opportunity. It would pay for almost everything and all I had to do was get a plane ticket. I knew where I wanted to go：Spain，the country of dancers wearing flowing red dresses. So when I heard that I was going to Hungary, I was pretty shocked. But I decided to make the best of it，since it was，after all，a once-in-a-lifetime opportunity. Before I knew it，I was on the airplane, leaving for Budapest International Airport, Hungary.I had times when I almost gave up. Hungarian is the hardest language on the planet. Cultural differences occasionally embarrassed both my peer teens and me. I had to give up eating carrots, my beautiful favorite，for they think carrots are rubbish in their country. The change in the landscape was amazing, looking nothing like skyscrapers, bullet trains，cars，and people in tiny houses that I had been accustomed to. Gradually, I fell in love with the relaxing lifestyle, the warm-hearted people, and getting home at 2：30 p. m. at the latest from school. And I was sad to leave on my very last day.Having the host family who took me as one of their own members was the best thing I，ve ever experienced. From my little sisters，I learned how to embrace life to its fullest. From my brothers I learned that it’s OK for a boy to run around the house. From my host parents I learned to stay positive，to smile, and that when you pick the right persons and take their hands，suddenly, you become friends.28. How did Jonathan feel when he was told to go to Hungary?A. Excited and satisfied.B. Confused and shocked.C. Amazed and embarrassed.D. Delighted and interested.29. Why did Jonathan still decide to go to Hungary instead of Spain?A. He didn’t like Spain.B. He wanted to learn Hungarian.C. It was a rare chance.D. Going to Hungary was much cheaper.30. What can we learn about Jonathan during his stay in Hungary?A. He fell in love with eating carrots.B. He couldn’t wait to leave.C. He was surprised by the landscape.D. He quickly got used to the life there.31. According to Jonathan, the host family_.A. changed him completelyB. taught him how to dance wellC. treated him as equally as a studentD. showed him the good things of life。
