2.例题展示
The first time I went abroad was when I went to London.It was in the summer holidays
about five or six years ago that I went with my friends.The plane and train were quite expensive,so
we decided to travel by coach(长途汽车).We left at five o'clock in the morning and the
journey to London took about sixteen hours.
Unfortunately,I thought the ring fell out of my pocket during the game,and I had to buy
another one.I really enjoyed visiting London,though the youth hotel was not perfect.Next time,
I will stay at the Ritz,but I will never feel as excited as I did that first time.
()What does the author think of his first trip to London?
A.He was disappointed.
B.He was unhappy.
C.He was excited.
D.He was bored.
【解析】根据文章最后一句“Next time,I will stay at the Ritz,but I will never feel as excited
as I did that first time.”可知,作者第一次去伦敦时非常兴奋,C选项正确。其他选项均
与文意不符。
