15．Did you know that sixty percent of your body weight is water？However，a loss of only two percent of this water through dehydration（脫水）during exercise can significantly affect your performance．The more you sweat，the more your exercise performance declines，unless you drink enough to replace your loss of fluids．
When you lose too much water，you can overheat quite easily，especially in a warm environment．But this is not the only problem you may faced with．Dehydration leads to your heart pumping much faster，which means exercise becomes more difficult and requires more effort．Despite these problems，however，many of us simply do not take enough fluids in when we head for the gym or set out on a run．
So why is this？How do we manage to lose so much water without simply drinking more to replace it？Well，it is s easier than you think．When we are at rest，we quickly become aware that we are thirsty and will put that right by having a drink．When we exercise，on the other hand，our thirst mechanism（結(jié)構(gòu)）does not work as effectively，so we don't notice early enough that we are actually thirsty．In fact，we only start to feel thirsty when we have already lost around two percent of our body weight．
Another problem is that，the more dehydrated we become during exercise，the more difficult it is to prevent further dehydration-because our stomachs become intolerant to fluids and we do not absorb water properly，just when we need it most．
The key thing about fluids and exercise is to manage your intake properly-regular small amounts are better，and some should be drunk before the period of exercise begins．You also need to match your intake to the sort of exercise you are doing．For instance，for one hour of exercise，such as taking part in a 10km run，you need to drink about two extra liters of water．For longer periods of exercise，sports drinks are recommended．

32．We know from the text that during exercise，dehydrationB．
A．can be easily avoided
B．will lead to poor performance
C．can cause many health problems
D．will be controlled whenever we drink again
33．Why do people suffer from dehydration easily during exercise？C
A．Their thirst mechanism stops working．
B．Their focus is on the exercise．
C．Their thirst response is slow．
D．Their stomachs are full．
34．When exercising，you are advised toB．
A．have regular breaks
B．drink water accordingly
C．drink sports water in advance
D．have at least two liters of water
35．What would be the best title for the text？C
A．Keep fit
B．Say no to sports!
C．Time to get drinking!
D．Ways to avoid dehydration．

18．A solar bag is a long plastic bag made from very thin plastic and colored black to take in solar energy．The heated air inside the bag causes the bag to float．Although the solar bag looks similar to a regular black trash bag，the key difference is the thickness of the plastic．A great science experiment might be testing bags of different thicknesses to see which one floats the highest!
Materials
v  Solar bag
v  Solar bag string
Notice that the bag is made out of a lightweight plastic material．Be careful when dealing with the bag since the pla stic will tear easily．
Carefully take the plastic bag from the packaging and hold one of the op en end of the bag．Tie this end with string．
The best time for a launch is in the cool morning．We have not had much success with a launch in the middle of a hot day．
Choose a proper place for the launch．Find a field clear of any buildings，trees and power lines．Choose a day to do the experiment when it is sunny and free of any wind．
Put the solar bag onto a soft surface like grass．Have one person hold the bag open as you begin to run around and fill the bag with air．
Fill the bag with air until about 2 feet remains without air so that you can hold it in your hand．Close the end and use a string to keep it on the ground．
The last part of the work is done by the sun．Gather around the giant bag but try not to touch it-sharp fingernails will easily break the thin plastic．Be careful!The outside of the bag also gets very hot to the touch．It's important to remember that it may t ake as long as ten minutes for the air inside to heat up enough to cause the bag to float．
25．What's the difference between a Solar Bag and a regular black trash bag？B
A．The weight．
B．The thickness．
C．The material．
D．The color．
26．The best time to launch a Solar Bag is inA．
A．a(chǎn) sunny cool morning without any wind
B．a(chǎn) sunny hot afternoon without any wind
C．a(chǎn) sunny cool morning with some wind
D．a(chǎn) sunny hot afternoon with some wind

2．A report brought back by most visitors to the US is how friendly，polite，and helpful most Americans were to them．To be fair，this observation is also frequently made of Canada and Canadians，and should best be considered North American．There are，of course，exceptions．Small-minded officials，rude waiters，and ill-mannered taxi drivers are hardly unknown in the US．Yet American's friendliness and helpfulness is an observation made so frequently that it deserves comment．
For a long period of time and in many parts of the country，a traveler was a welcome break in an otherwise dull existence．Dullness and loneliness were common problems of the families who generally lived distant from one another．Strangers and travelers were welcome sources of distraction，and brought news of the outside world．
The tough realities of the border also shaped this tradition of hospitality．Someone traveling alone，if hungry，injured，or ill，often had nowhere to turn except to the nearest settler agent．It was not a matter of choice for the traveler or only a charitable impulse （沖動） on the part of the settlers．It reflected the hardship of daily life：if you didn't take in the stranger and take care of him，there was no one else who would．And someday，remember，you might be in the same situation．
Today there are many charitable organizations which specialize in helping the exhausted traveler．Yet，the old tradition of hospitality to strangers is still very strong in the US，especially in the smaller cities and towns away from the busy tourist routes．"I was just traveling through，got talking with this American，and pretty soon he invite d me home for dinner，amazing．"Such observations reported by visitors to the US are not uncommon，but are not always understood properly．The casual friendliness of many Americans should be understood neither as superficial（表面的）nor as artificial（虛偽的），but as the result of a historically developed cultural tradition．
As is true of any developed society，in America a complex set of cultural signals and customs is the basis of all social inter-relationships．And，of course，speaking a language does not necessarily mean that someone understands social and cultural patterns．Visitors who fail to"translate"cultural meanings properly often draw wrong conclusions．For example when an American uses the word"friend"，the cultural meanings of the word may be quite different from those it has in the visitor's language and culture．It takes more than a brief encounter on a bus to tell polite customs from individual interest．Yet，being friendly is a virtue （美德） that many Americans value highly and expect from both neighbors and strangers．

29．In the eyes of visitors from the outside world，D．
A．rude taxi drivers are hardly seen in the US
B．small-minded officials deserve a serious comment
C．Canadians are not so friendly as their neighbors
D．most Americans are ready to offer help
30．We can know from the last paragraph thatA．
A．culture has an influence over social inter-relationship
B．polite customs and individual interest are inter-related
C．various virtues shows themselves only among friends
D．social inter-relationships equal the complex set of cultural customs
31．Families who lived far from one another used to entertain strangersC．
A．to improve their hard life       
B．in view of their long-distance travel
C．to add some taste to their own daily life    
D．out of a charitable impulse
32．The tradition of hospitality to strangersB．
A．tends to be superficial and artificial
B．is generally well kept up in the United States
C．is always understood properly          
D．has something to do with the busy tourist route．

20．Cheektowaga Central Middle School can be a lot of fun．It has game nights and student dances，after-school activities，and sports teams．However，students must earn the right to join in the fun．If they don't behave well，they're banned from participating in after-school activities．
Teachers and parents say the threat （威脅） of being excluded （排除在外） appears to be working．Kenny says it taught him that actions have consequences："I learned that I need to be balanced in both my work and athletics to be rewarded for working hard．"Parent Sondra LaMacchia told The New York Times that her 14-year-old daughter is learning responsibility at Cheektowaga Central．She used to perform poorly in her studies，so then she was banned from a school dance．The message got through loud and clear．"It's nobody's fault but hers，"LaMacchia said．
Although exclusion（排擠）may help teach responsibility，some psychologists say it can also be threatening，especially for students who often cause，or may cause，trouble in school．They might become more aggressive and antisocial，which is exactly what schools like Cheektowaga Central want to prevent．
Should schools exclude students from activities to get them to behave well？I believe teens need school activities and that inclusion（包含） can be the answer．For some troubled students，activities can be their motivation to stay in school．"Activities such as sports may be the only thing keeping certain students in school，"says Duace Wood，a teacher at Mohonasen High School in Rotterdam．Getting involved in after-school activities keeps troublesome students in class．Even if they don't do as well as their classmates，they are still learning．The more time they spend at school，the less time they have to think about starting trouble．Teams also provide support and role models，and they help build the confidence that students need to succeed．If students who don't behave well are banned from activities，they might give up on school altogether．

29．Paragraph 2is developed byC．
A．a(chǎn)nalyzing causes
B．examining differences
C．giving examples
D．following the time order
30．Parent Sondra LaMacchia supports the policy of exclusion becauseC．
A．it provides role models
B．her daughter is aggressive
C．it helps teach responsibility
D．her daughter hates taking exercise
31．In Paragraphs 3and 4，the author mainly focuses onB．
A．students who are good at sports
B．students who often cause trouble
C．teens who do well in their studies
D．teens who always behave themselves
32．What is the author's attitude toward the school's policy of exclusion？D
A．Supportive．
B．Sympathetic．
C．Satisfied．
D．Negative．
