6.-Did you visit the famous cultural relics last month?
-No,we____ it,but we spent too much time shopping.(  )
A.could have visitedB.must have visited
C.can't have visitedD.shouldn't have visited

分析 ---上个月你们参观那个有名的文化遗址了吗?---没有,我们本来可以去的,但是我们在购物上花了太多的时间.

解答 答案:A
答语表达的意思是:如果我们不在购物上花太多的时间,我们本来是可以去参观那个有名的文化遗址的;此处表达了与过去事实相反的情况,相当一个虚拟条件句,即:If we hadn't spent too much time shopping,we could have visited it;A.could have visited 本来可以去参观;B.must have visited 表示对过去发生的事比较肯定的推测;"一定是参观了",用在此处不合句意;C.D是否定的表达,因此也不合句意;故选A

点评 本题考查了情态动词在虚拟语气中的运用.做此类题时,首先要根据句意分析判断该句是否是虚拟语气句,然后确定是对过去,现在还是将来的虚拟,从而选择相应的表达方式.

5.Secret codes (密码)keep messages private.Banks,companies,and government agencies use secret codes in doing business,especially when information is sent by computer.
   People have used secret codes for thousands of years.(36)DCode breaking never lags(落后) far behind code making.The science of creating and reading coded messages is called cryptography.
   There are three main types of cryptography.(37)EFor example,the first letters of"My elephant eats too many eels"Spell out the hidden message"Meet me."
(38)GYou might represent each letter with a number,for example,Let's number the letters of the alphabet,in order,from 1 to 26.If we substitute a number for each letter,the message"Meet me"would read"13 5 20 13 5."
   A code uses symbols to replace words,phrases,or sentences.To read the message of a real code,you must have a code book.(39)FFor example,"bridge"might stand for"meet"and"out"might stand for"me."The message"bridge out"would actually mean"Meet me."(40)AHowever,it is also hard to keep a code book secret for long.So codes must be changed frequently.

A.It is very hard to break a code without the code book.
B.In any language,some letters are used more than others.
C.Only people who know the keyword can read the message.
D.As long as there have been codes,people have tried to break them.
E.You can hide a message by having the first letters of each word spell it out.
F.With a code book,you might write down words that would stand for other words.
G.Another way to hide a message is to use symbols to stand for specific letters of the alphabet.
