This is another reason for some of the mystery about nuclear radiation．Serious damage can be done without the victim being aware at the time that damage has occurred．A person can be irradiated（辐射）and feel fine，then die for cancer five，ten，or twenty years later as a result．Or a child can be born weak as a result of radiation absorbed by its grandparents．
Radiation can hurt us．We must know the truth．
24．What is the most dangerous factor of nuclear power?
A．Radiation
B．Quantity D．Place
C．Amount
25．Which of the following statements is true?
A．Nuclear radiation can do harm to human beings． B．Nuclear radiation cannot do harm to human beings． C．Nuclear radiation can be detected by human senses． D．Nuclear radiation is just like common radio waves．
26．Why does nuclear radiation have a certain mystery?
A．Because human beings learn its harmfulness．
B．Because it can do harm to a person while the victim isn't aware the damage has occurred． C．Because nuclear radiation can kill a person very easily．
D．Because human beings have no effective machine in order to detect nuclear radiation． 27．If a human being is hit by nuclear radiation，he may _______．
A．die of cancer after many years B．die immediately

Nearly everyone agrees that money doesn't buy as much as it used to，no matter when you want to spend it．This is certainly true of the paper money that passes so quickly through one's hands．But what about coins that seem to do very little except stay in purses and pockets? Unlike notes，metal money becomes more valuable the longer it is held，especially if it is put away where it won't get scratched (破坏）or worn．Why is this? One reason is that coins，being more durable (持久的），fall more readily into a category for collectors．Naturally，the rarer gold pieces must become more valuable as the price of this metal
goes up．
But，curiously，one of the rarest coins in the world is not made of gold，but of the relatively cheaper silver．In 1840，the United States mint (造币厂）struck 19570 silver dollars．That is what its records show．Today only six of this original number remain and these are unlikely ever to reach the auction (拍卖）market．So what happened to some 19564 large silver coins，not the easiest sort of things to lose? One of the more romantic theories is that they were part of the payment to Napoleon for the American land then known as Louisiana．But they never reached France．Somewhere in the Gulf of Mexico，the ship transporting them was sunk，either by a storm or by pirates (海盗）．The probable answer to the mystery is that they were melted down — since the silver value was greater than the actual value of the coin．What really happened to the rest will probably always remain a mystery．What is known is that whoever can come up with one will find himself instantly rich．
28．Which of the following is true of a coin?
A．The longer it is held，the less valuable it becomes． B．The more it wears out，the more valuable it becomes． C．The less it gets scratched，the less it values． D．The longer it lasts，the more it values．
29．According to this passage，one of the rarest coins in the world is made of _______．
A．silver C．copper
B．gold D．paper
30．Coins become more valuable because _______．
A．they stay in purses and pockets B．the price of metal goes up
C．they fall more readily into a category for collectors due to their duration D．Both B and C
31．What really happened to some 19564 large silver coins?
A．They were melted down．
B．They were sunk in the Gulf of Mexico． C．It is still a mystery． D．They were stolen by pirates．
D
Anyone who has ever lost keys or money will have wished for a simple but effective way to make sure it never happens again．A US company is trying to help．
Using a tiny microchip which is implanted into the arm，they have come up with a replacement for cash or credit cards that cannot be left at home or dropped on the bus．
The Verichip is about the size of a grain of rice and works using radio frequency identification technology．At a shop，a radio frequency “reader” would send a signal and the chip in your arm would respond with your unique identity number．That would give the “reader” your financial information，and money could be taken directly from your accounts and you wouldn't even have to reach for your wallet．
The company also hopes to include other information on the chip，such as medical records，building security codes(密码）and passwords，making life even easier．
But not everyone is happy with the developments．Critics say that a lot can go wrong with the chip．A clever thief could build a fake(假的）reader that would steal your information without you knowing．So your money could still be stolen．Privacy is a big issue too．Stores，or even the government，only need to track the chip to find out what you buy，how much you spend and where you go．
And if you wanted to get rid of your chip,you would need an operation to remove it． 32．The Verichip is ．
A．the identity number C．a tiny microchip 33．Paragraph 3 is mainly about ．
A．how the Verichip works B．the importance of the Verichip C．the development of the Verichip D．how money is taken from your accounts 34．Which is true of the Verichip?
A．Your information on it will always be safe． B．Medical records have already been included． C．You can easily reach for your wallet using it． D．An operation has to be performed to remove it． 35．What can be inferred from the text?
A．All people are satisfied with the chip． B．The Verichip company has financial problems． C．The chip needs improving to be widely accepted． D．Many people have the experience of losing keys or money． 第二节（共5小题:每小题2分，满分10分）

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。 “Look it up in the dictionary” is the usual comment when people are in doubt about the meaning or spelling of a word．Dictionaries are considered the final authority on these matters as well as on pronunciations and other facts about a word．
Until a few hundred years ago，however，people could not “look it up” because there were no English dictionaries．The ancient Greeks and Romans and the scholars of the Middle Ages had made lists of Latin and Greek words． 36 The first great English dictionary listing both common and uncommon words was written by Samuel Johnson in 1755．
In America，the most famous name in dictionary writing is that of Noah Webster．He stressed American rather than British ways of speaking．His great dictionary，which first appeared in 1828，has been republished many times． 37 The latest edition is still considered “the” dictionary．It defines over 450，000 words，including radar，television and many others undreamed-of by Webster．
38 The huge ones that rest on stands in libraries are called unabridged，meaning “not shortened” ．They tell not only a word’s meaning and spelling but also its pronunciation，origin，history，part of speech，grammatical forms and ways of use．The smaller ones do not provide all the information．
39 A bilingual(两种语言的）dictionary，such as a Spanish-English dictionary，translates words from one language into another．A thesaurus(分类词典）lists other words that mean the same as each listed word．A gazetteer lists place names，and a glossary is a small dictionary in a book defining technical words in that book．There are also dictionaries of scientific terms and ones on many other topics．There is even a dictionary of slang． 40 The dictionary is one of our most valuable language tools．
A．Each time，it has been updated． B．General dictionaries are not the only kind． C．Thus there are many kinds of special dictionaries．
D．In a general dictionary，each word may have multiple meanings． E．Dictionaries that list all kinds of words are known as general dictionaries． F．Over the previous 150 years more than 20 dictionaries had been published． G．But it was not until 1604 that a book of uncommon English words appeared．
