5．我們承擔不起犯任何錯誤．
Wecan't affordtomake anymistakes．．

分析 We can't afford to make any mistakes．

解答 答案：We can't afford to make any mistakes．表達的是客觀事實用一般現(xiàn)在時，承擔不起用can't afford to do sth．這里是否定句，故make any mistakes犯錯誤，故答案是We can't afford to make any mistakes．

點評 1．a(chǎn)fford是動詞，意為"買得起，擔負得起"．通常與can，could，be able to連用，尤用于否定句或疑問句中．如：
They couldn't afford $50 for a ticket．
他們拿不出50美元買一張票．
Can we afford a new car？
我們能買得起一輛新車嗎？
2．a(chǎn)fford后面常跟帶to的動詞不定式．如：
We can't afford to go abroad this summer．
今年夏天我們沒有足夠的錢出國．

13．If the rose can be said to be a special flower，then the apple can be said to be a special fruit．It is very important in American culture．American stories speak of Johnny Appleseed，who went throughout America collecting apple seeds and planting apple trees．He had a great love for nature and went through fields and farms adding richness and beauty to the country．
One of the first sayings taught to school children is，"An apple a day keeps the doctor away．"This short saying encourages children to eat fresh fruit to keep healthy．If someone always says good words to a person，people will call him an"apple polisher"．This，however，is not a good name．If someone is very dear to us，we say that he or she is the"apple of our eye"．
Most people believe that the fruit which Eve gave to Adam was an apple，even though the Bible（圣經(jīng)） never says so．The apple，therefore，is a deep part of the language and stories of America．
An apple is also delicious．Apples can be cooked in many ways，used as a dessert，and made into sweet juice．
In many parts of the country during the harvest season，a popular activity is to go into an apple garden to pick apples．Washington，D．C．a(chǎn)nd New York are both famous for their apples．
Finally，when it's time to take a vacation to American cities，one can always visit New York，which is"the biggest apple"of all the American cities．
58．What does the underlined phrase"apple polisher"mean？B
A．Something for cutting apples．
B．A person who likes to please others．
C．A person who is dealing with fruits．
D．A machine for cleaning apples quickly．
59．"An apple a day keeps the doctor away"is a proverb aboutD．
A．cooking
B．medicine
C．shopping
D．health
60．Which of the following is TRUE with apples？C
A．Apples are medicine．
B．Apples are the most important food．
C．New York is famous for its big apples．
D．The Bible says Adam was given an apple．
61．The passage is mainly aboutB．
A．stories about the apple 
B．a(chǎn)pples in American culture
C．some famous sayings of the apple 
D．big cities that is famous for apples．
