12．On a hot summer day，there are few things that are more wonderful than a nice cool pool1（16）EAnd it is completely relaxing．Of course，if you have children，there are certain measures you s hould take to keep them safe，whether you have a pool in your backyard or you are going to a public pool．
Go swimming together．No person should ever swim alone．Though many people do，the simple truth is that it only takes a second for people to become injured or drown．（17）FHaving some one there with you can make the difference between life and death．This is especially true for young children．If your children is under the age of 5，you should never allow them to swim out of arm's length．
（18）AKids love to chase one another through the water and to splash and jump around．But it is important to teach children not to jump on top of one another and to watch their surroundings in the water，so that they do not accidentally knock into others，injuring them．Playing around in the pool is very interesting but dangerous．
    Keep it locked．If you have a pool，you must have a locking gate around your pool．（19）DKeep the gate locked at all times，even when you are in the pool．It is terrible for ch ildren to steal into the pool．
    Know the way out．（20）BMake sure that t hey know where all ladders are and how to enter and get out of the pool properly．Although your children may be able to lift themselves out of the pool using the side，that is not the safest way to go．

A．Don't play around in the pool．
B．Be sure to show all children the proper way to exit（離去） the pool．
C．Swimming under water is forbidden in the pool．
D．This is to prevent children from entering the pool without your permission．
E．Slipping into the water seems like the perfect way to deal with the heat．
F．Something sad happens every year．
G．Make sure kids know food should be eaten either before or after swimming．

點評 解題策略
1）從意思上判斷 在做題時最重要的是要讀懂空白前后的句子，正確理解了這些句子后，根據(jù)意思的連貫性、邏輯性或者線索詞從選項中選取正確答案．在讀懂意思的基礎(chǔ)上，再利用線索特征詞等進一步確認答案．
2）從詞匯上鎖定線索 做保持對一些線索詞的敏感是非常重要的，要好好關(guān)注空白前后的名詞和動詞，然后在選項中查找它們的近義詞、反義詞、同義詞、同類詞等．其次是一些專有名詞，比如說數(shù)詞、代詞、時間、年代、地點/名稱等．尤其是在讀不懂句子的情況下，利用這樣的線索詞尋找答案是很有效的方法．
3）從關(guān)聯(lián)詞作為切入點 通常，英語的句段之間經(jīng)常會運用關(guān)聯(lián)詞表示過渡和銜接，讓文章的思路與更清楚、邏輯更連貫，因此文章中和選項中表示各種邏輯關(guān)系的路標性信號詞在選擇答案時都是很重要的線索．在做題時可將這三個層面的線索很好地結(jié)合起來．

3．Nuclear power's danger to health，safety，and even life itself can be summed up in one word：radiation．
Nuclear radiation has a certain mystery about it，partly because it cannot be detected by human senses．It can't be seen or heard，or touched or tasted，even though it may be all around us．There are other things like that．For example，radio waves are all around us but we can't detect them，sense them，without a radio receiver．Similarly，we can't sense radioactivity without a radiation detector．But unlike common radio waves，nuclear radiation is not harmless to human beings and other living things．
At very high levels，radiation can kill an animal or human being immediately by killing masses of cells in vital organs．But even the lowest levels can do serious damage．There is no levels of radiation that is completely safe．If the radiation does not hit anything important，the damage may not be serious．This is the case when only a few cells are hit，and if they are killed immediately．Your body will replace the dead cells with healthy ones．But if the few cells are only damaged，and if they reproduce themselves，you may be in trouble．They reproduce themselves in a deformed way．They can grow into cancer．Sometimes this does not show up for many years．
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（輻射）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．
32．How can nuclear radiation kill an animal？D
A．By damaging its heart．
B．By killing a few cells．
C．By hitting any place in its body．
D．By killing many cells in important organs．
33．The word"deformed"in paragraph 3has the similar meaning toA．
A．unnatural      B．normal      C．usual      D．proper
34．What can we infer from the passage？D
A．We can't detect radioactivity even with modern equipment．
B．Only radiation at very high levels can kill an animal or human being．
C．If a few cells are only damaged，healthy cells will take the place of dead ones．
D．Radiation is harmful no matter what level it is．
35．What's the author's main purpose in writing this passage？C
A．Discussing the cause of cancer．
B．Solving the mystery about radiation．
C．Emphasizing the importance of protection of radiation．
D．Introducing the nuclear power．

20．Perhaps you think you could easily add to your happiness with more money．Strange as it may seem，if you're unsatisfied，the issue is not a lack of means to meet your desires but a lack of desires-not that you cannot satisfy your tastes but that you don't have enough tastes．
Real riches consist of well-developed and hearty capacities（能力）to enjoy life．Most people are already swamped（淹沒）with things．They eat，wear，go and talk too much．They live in too big a house with too many rooms，yet their house of life is a hut．
Your house of life ought to be a mansion（豪宅），a royal palace．Every new taste，every additional interest，every fresh enthusiasm adds a room．Here are several rooms your house of life should have．
Art should be a desire for you to develop simply because the world is full of beautiful things．If you only understood how to enjoy them and feed your spirit on them，they would make you as happy as to find plenty of ham and eggs when you're hungry．
Literature，classic literature，is a beautiful，richly furnished room where you might find many an hour of rest and refreshment．To gain that love would go toward making you a rich person，for a rich person is not someone who has a library but who likes a library．
Music like Mozart's and Bach's shouldn't be absent．Real riches are of the spirit．And when you've brought that spirit up to where classical music feeds it and makes you a little drunk，you have increased your thrills and bettered them．And life is a matter of thrills．
Sports，without which you remain poor，mean a lot in life．No matter who you are，you would be more human，and your house of life would be better supported against the bad days，if you could，and did，play a bit．Whatever rooms you might add to your house of life，he secret of enjoying life is to keep adding．

59．The author intends to tell us thatD．
A．true happiness lies in achieving wealth by fair means
B．big houses are people's most valued possessions
C．big houses can in a sense bring richness of life
D．true happiness comes from spiritual riches
60．The underlined sentence in the second paragraph probably implies thatB．
A．however materially rich，they never seem to be satisfied
B．however materially rich，they remain spiritually poor
C．though their house is big，they prefer a simple life
D．though their house is big，it seems to be a cage
61．It can be learned from the passage thatC．
A．more money brings more happiness    
B．a(chǎn)rt is needed to make your house beautiful
C．literature can enrich your spiritual life  
D．sports contribute mainly to your physical fitness
62．What would be the best title for the passage？A
A．House of Life  
B．Secret of Wealth  
C．Rest and Refreshment  
D．Interest and Enthusiasm．

1．In the rush to get to school，you drop a piece of toast on the floor．Do you throw it away or decide it's still OK to eat？If you're like most people，you eat it．Maybe you follow the"5-second rule"，which claims foods are safe to eat if you pick them up within 5seconds after dropping them．But you might want to think again．Scientists now say that 5seconds is all it takes for foods to become polluted with enough bacteria（細菌）to make you sick．
Bacteria can cause many kinds of illnesses．Some kinds of bacteria can grow on food．If you eat foods on which these bacteria are growing，you can become sick．
One of these food-borne bacteria is Salmonella．It makes 1.4million people sick every year．Salmonella is often found in raw eggs and chicken．Cooking kills these bacteria，which is why it is so important to cook eggs，chicken，and other foods thoroughly．
But how long does it take these bacteria to pollute food？A team of scientists in South Carolina did an experiment．First，they placed an amount of Salmonella on three surfaces； wood，tile （瓦片），and carpet．They placed a piece of bread and a piece of bologna（一種大紅腸）on each surface for 5，30，or 60seconds．After just 5seconds，both the bread and the bologna picked up enough bacteria to make you sick．
So，forget the 5-second rule．If your toast drops on the floor，throw it away and get another piece of clean toast．And this time，be careful not to drop it!
32．In which part of a newspaper can you most probably find this passage？B
A．Culture      B．Health     C．Advertisement    D．Technology
33．After dropping a piece of toast，a person who follows the"5-second rule"willB．
A．throw away dirty toast immediately and go away
B．pick up the toast as quickly as possible and eat it
C．eat the toast within 5seconds and feel pleased
D．get another piece of clean toast quickly and eat it
34．The scientists in South Carolina did the experiment toA．
A．see how quickly bacteria can pollute food
B．show that the 5-second rule is correct
C．see how harmful bacteria are to people's health
D．show that bacteria grow at different speeds on different foods
35..What's the writer's attitude to the"5-second rule"？B
A．positive．B．negative．C．neutral（中立）．D．cautious（謹慎）
