7．It's acomfort（安慰）to know that you are safe．

分析 知道你安然無恙是令人安慰的事．

解答 答案：comfort 
考查名詞．根據(jù)所給的漢語提示"安慰"和空前的冠詞a可知，此處應(yīng)用名詞單數(shù)形式，"安慰"的英語是comfort，故填comfort．

點評 名詞是中學(xué)英語的重要語法，解題時首先要根據(jù)語境和句子結(jié)構(gòu)的需要推斷出空所需要的詞性，然后根據(jù)句意和所給的漢語提示寫出正確答案．

12．DNuclear power is the world's largest source of clean energy．Nuclear power plants（電廠） produce no controlled air pollutants，such as sulfur or greenhouse gases．The use of nuclear power in place of other energy sources helps to keep the air clean，preserve the earth's climate，and prevent acid rain．Howeve r，there exist safety concerns if the plant is not operated correctly or unforeseen things happened when the plant was developed，as happened at the Fukishima（福島） plant in Japan．It may cause damage to everything，including our health．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．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．
33．How can nuclear radiation kill an animal？A
A．By killing many cells in important organs．
B．By killing a few cells．
C．By hitting any place in its body．
D．By damaging its heart．
34．If a human being is hit by nuclear radiation，he mayD
A．die of cancer after many years                        
B．die immediately  
C．have a child who may be born weak                   
D．a(chǎn)ll of the above
35．What's the author's main purpose in writing this passage？B
A．Discussing the cause of cancer．
B．Solving the mystery about radiation．
C．Emphasizing the importance of protection from radiation．
D．Introducing the nuclear power．

19．How to get along with your bossIn your career，you may have to report to a manager，the person you call boss．
（36）F Here are some tips to help you develop an effective relationship with your boss．
The first step is to develop a positive relationship with your boss．Relationships are based on trust．（37）AKeep timetable commitments （承諾）．Never blindside （偷襲） your manager with surprises that you could have predicted or prevented．Keep him/her informed about your projects and interactions with the rest of the organization．
Tell the boss when you've made an error or one of your reporting staff has made a mistake．（38）CLies or efforts to mislead always result in further stress for you as you worry about getting"caught"．Communicate daily or weekly to build the relationship．
Recognize that success at work is not all about you．（39）E Identify your boss's areas of weakness or greatest challenges and ask what you can do to help．What are your boss's biggest worries？How can your contribution reduce these concerns？Understand your boss's goals and priorities．Place emphasis in your work to match her priorities．Think in terms of the overall success of your department and company，not just about your narrow world at work．
（40）DDoes he/she like frequent communication，autonomous employees，requests in writing in advance of a meeting，or informal conversation as you pass in the halfway？Your boss's preferences are important．The better you understand them，the better you will work with him/her．
If you sometimes disagree and occasionally experience an emotional reaction，don't hold hatred．Don't make threats about leaving．Disagreement is fine．You need to come to terms with the fact that your boss has more authority and power than you do．

A．Do what you say you'll do．
B．Value your boss's time．
C．Cover-ups （掩飾） don't contribute to an effective relationship．
D．Identify what he/she values in an employee．
E．Put your boss's needs at the center of your universe．
F．The relationship with your boss is important for your work success and career progress．
G．Learning how to read your boss's moods and reactions is also helpful．
