2．When we analyze the salt salinity （鹽濃度） of ocean waters，we find that it varies only slightly from place to place．Nevertheless，some of these small changes are important．There are three basic processes that cause a change in oceanic salinity．One of these is the subtraction （減少） of water from the ocean by means of evaporation （蒸發(fā)）．In this manner，the salinity is increased，since the salt stays behind．If this is carried to the extreme，of course，white salt would be left behind； this，by the way，is how much of the table salt we use is actually obtained．
The opposite of evaporation is precipitation，such as rain，by which water is added to the ocean．Here the ocean is being diluted （稀釋） so that the salinity is decreased．This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean．Thus salinity may be increased by the subtraction of water by evaporation，or decreased by the addition of fresh water by precipitation．
Normally，in hot regions where the sun is very strong，the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation．Similarly，in coastal regions where rivers dilute the sea，salinity is somewhat lower than in other oceanic areas．
A third process by which salinity may be altered is associated with the formation and melting of sea ice．When seawater is frozen，the dissolved materials are left behind．In this manner，seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared．Of course，when this ice melts，it will tend to decrease the salinity of the surrounding water．
In the Weddell Sea，the densest water in the ocean is formed as a result of this freezing process，which increases the salinity of cold water．This heavy water sinks and is found in the deeper portion of the oceans of the world．
60．This passage mainly tells us aboutB．
A．the analysis of the salinity of ocean waters
B．the causes of the variation in oceanic salinity
C．the importance of the changes in oceanic salinity
D．the different forms of salts in ocean waters
61．It can be known from the passage that increase in the salinity of ocean water is caused byC．
A．melting of sea ice                  
B．precipitation   
C．evaporation                     
D．supplement of salt
62．Which of the following is not the cause of the decrease in the oceanic salinity？C
A．Precipitation．
B．Rain and snow．
C．Formation of ice．
D．Addition of water by rivers．

17．Health is the most important thing in the world．Nothing is more important than health．If one takes away our money，houses，cars，or even our clothes，we can still survive．（36）D That is why we always try to eat in a healthy way and exercise regularly．
How can we keep healthy？In order to eat healthily，I usually avoid eating food high in fat，like French fries or cookies，which are junk foods．（37）F  Besides，I only eat little meat．
（38）C  Taking exercise every day helps us build a strong body．Regular exercise is an important part of keeping me healthy．
What's more，I think friends are an important part of one's health．（39）A  I always feel better when I am with friends than when I am alone．When I am with my friends，I always laugh．Laughing is also an important part of health．It is good to stay with my friends．
By eating properly and exercising regularly，I can keep my body at a proper weight and keep healthy．By spending time with my friends，I can keep my mind as well as my body happy．These things sound easy to do，but not many people can manage them．（40）E

1．The new year brought new desks for students at Vallecito Elementary School，in San Rafael，California．The last three of the school's 22 classrooms switched from seated desks to standing desks．"It's now the first all-standing school，"Juliet Starrett told TFK．She started the group Stand Up Kids．Her goal is to have every U．S．public school kid using a standing desk within the next10years．
Starrett's daughters-Georgia，10，and Caroline，7-attend Vallecito．They are thrilled with their desks．"You feel happier，you're less tired，and you're more active，"Georgia says．
Some of the desks have wheels and fidget bars．The bars let kids move in a way that doesn't disturb the class．Wheels allow the desks to be moved easily．The desks also adjust to different heights．Kids take breaks by sitting on the floor or on stools．
There is the trend of designing things to make them easy and safe to use．According to Mark Benden，director of the Texas A&M Center，standing workers are more focused and healthier．He says his research shows that kids using standing desks are more engaged and burn more calories．In December，researchers in New Zealand，Australia，and the United Kingdom released similar findings．But not everyone is convinced standing is better than sitting．Some parents and teachers worry that kids will get tired and that standing for long periods of time may be harmful．And standing desks are more expensive．
Benden says both sitting and standing desks can cause problems if they are not the proper height．"Our message should not be‘Sit less，stand more，'"he says，"but‘Sit less，move more．'"

51．What is Paragraph 3 mainly about？C
A．Why standing desks are used．
B．Where standing desks are used．
C．How standing desks are used．
D．Who uses standing desks．
52．Mark Benden's research shows that kids using standing desksB．
A．feel more tired
B．a(chǎn)re more focused
C．get better scores
D．tend to eat more
53．Some parents and teachers worry that using standing desks mayC．
A．disturb the kids in class
B．leave the classroom noisy
C．harm the students'health
D．increase the teachers'workload．

2．It was the summer of 1965．DeLuca，then 17，visited Peter Buck，a family friend．
Buck asked DeLuca about his plans for the future．"I'm going to college，but I need a way to pay for it，"DeLuca recalls saying．"Buck said，‘You should open a sandwich shop．'"
That afternoon，they agreed to be partners．And they set a goal：to open 32 stores in ten years．After doing some research，buck wrote a check for﹩1000．DeLucarentedastorefront（店面）inConnecticut，andwhentheycouldn'tcovertheirstart-upcosts，Buck kicked in another﹩1000．
But business didn't go smoothly as they expected．DeLuca says，"After six months，we were doing poorly，but we didn't know how badly，because we didn't have any financial controls．"All he and Buck knew was that their sales were lower than their costs．
DeLuca was managing the store and going to the University of Bridgeport at the same time．Buck was working at his day job as a nuclear physicist in New York．They'd meet Monday evenings and brainstorm ideas for keeping the business running．"We convinced ourselves to open a second store．We figured we could tell the public，‘We are so successful，we are opening a second store．'"And they did-in the spring of 1966．Still，it was a lot of learning by trial and error．
But the partners'learn-as-you-go approach turned out to be their greatest strength．Every Friday，DeLuca would drive around and hand-deliver the checks to pay their suppliers．"It probably took me two and a half hours and it wasn't necessary，but as a result，the suppliers got to know me very well，and the personal relationships established really helped out，"DeLuca says．
And having a goal was also important．"There are so many problems that can get you down．You just have to keep working toward your goal，"DeLuca adds．
DeLuca ended up founding Subway Sandwich，the multimillion-dollar restaurant chain．

C．He was studying at the University of Bridgeport．
D．He rented a storefront for DeLuca．
58．What can we learn about their first shop？C
A．It stood at an unfavorable place．
B．It lowered the prices to promote sales．
C．It made no profits due to poor management．
