You want to know about my studying in America，right? Well，to tell you the truth，it is really an eye-opening experience．
In China，I had English classes five times a week since fifth grade．However，I didn’t know how different textbook English could be from everyday English until I came to Hotchkiss School，Connecticut．
When I first studied English，1 was told to say‘I am fine．’when people say‘How are you?’But in the USA，I found that people say‘I am good．’or‘I’m tired．’One day，someone greeted me with‘What’s up?’It made me confused．I thought for a moment and then smiled because I didn’t know what to say．
Since then，I have discovered more and more differences between Chinese and American cultures．
To my surprise，American girls spend a lot of time in the burning sun to get tanned(晒黑的)．However，in China，girls try every possible way to get their skin paler or
‘whiter’．
I was also surprised by how hard-working American students are．
In China，schoolwork is almost everything，so we study hard and that，so it．But here，a‘good’student gets good grades，does a lot for the public and plays sports or music．The kids here are so talented．I am starting to be sorry that I gave up playing the piano at an early age and that I have never thought about sports。
( A )6．According to the writer，textbook English is________everyday English．A．quite different from B．the same as
C．more difficult than D．easier than
( A )7．The underlined word‘confused’means‘_________’in Chinese．A．困惑的B．憧憬的C．悲痛的D．后悔的( D )8．A good American student spends his／her time__________．
A．only in doing homework B．only on sports or music
C．only in working for the public D．on studies，sports，music and public work ( D )9．Which of the following is NOT true?
A．The writer is now in the USA．
B．American girls love to have white skin．
C．US students are talented and hard-working．
D．The writer regrets(悔)that he gave up playing the piano．
( B )10．Which is the best title of the passage?
A．My own travel in the USA B．My studying in the USA
C．My opinion about the USA D．My friends in the USA
