10．
Would you believe that drinking water is one of the most healing things you can do for your body？It's true as long as it is pure，alkaline（碱性的）water．Yet most water is acidic．Water that（41）Dless than 7 on the PH scale is acidic．Water that is higher than 7 is alkaline．To support life，water needs to be on the alkaline side of the range，much like our bodies．
Drinking pure，alkaline water is important to great health．I believe that most of the disease （42）Gpeople in the Western world couldn't occur in a PH-balanced body．
Most tap water is highly acidic due to the （43）Iof various chemicals．Don't assume that bottled water is （44）Aa better choice than tap water．Most bottled water is of （45）Jquality and largely made up of tap water plus the off-gassing of chemicals from the plastic in which it is stored．Most bottled water is extremely acidic，making it harmful to your health and the health of the planet，too．
Water filtration（过滤） is a necessary part of our modern life．There are many water filtration systems that get rid of some of the harmful chemicals，but few systems that also （46）Kthe PH of water to increase its healing powers．Every company （47）Bthat its systems are the best．I've spent some time trying to find affordable water filtration systems．
Every cell in your body depends on enough water to ensure proper （48）C．It's important to drink between 12 and 20 cups of alkaline water each day．Every person has individual needs but if you are smaller than （49）Eand in excellent health，your water needs will obviously be lower than someone who is fat and in poor health．As your health problems improve and you lose any extra weight，you can reduce your water （50）Fto 12 cups each day．

9．Anyone planning to go camping or hiking should first learn to recognize poison ivy，（51）Athis plant can cause a rash resulting in reddened skin，an annoying itch，and painful blisters．A severe （52）Ccan even force a person to remain in bed or become hospitalized．The best way to （53）Bthese discomforts is to avoid the plant．P．F．Productions
Fortunately this plant is easy to （54）D．Whether it grows as a bush or a vine，the shape of it is always （55）A．Each leaf stalk has three glossy leaves，usually with jagged edges．In early spring the leaves are red，turning．And then the autumn comes，the leaves （56）Bto become bright red or orange．The poison ivy plant is found （57）Deverywhere in North America．Because many birds eat its berries，its seeds are （58）Adistributed．The plant loves the sun and flourishes along beaches，in fields，and by roadsides．It also grows（59）Cin light shade and is often found in parks and pine forests．However，in thick woods the story is different．It is not （60）Athere．That is because the leaves of the trees block out the sun，which the plant needs to grow．
The poison in poison ivy is in the form of an oil that is in all parts of the plant．It is extremely （61）C．Merely touching the plant is enough contact for a person to be infected by the （62）A．Touching clothing or shoes that have brushed against the plant can also cause a rash and blisters．Even the smoke from a fire where poison ivy is burning can cause the skin poisoning．
A person who makes （63）Bwith the plant should wash all infected areas with a strong laundry soap as soon as possible．Clothes that have come in contact with the （64）Cshould be dry cleaned or washed in soap and water．There is one good way to prevent the （65）AStay away from the plant!

7．In American culture，you may find some very sensitive topics that require you to think again before you put them forward．They are as follows：
Age．It is a very sensitive （1）Bto many Americans．In this culture，the thought of growing older is a （2）B one and most of us，if possible，would like to have nothing to do with it．So many Americans work hard to （3）D a youthful appearance．The last thing they want to be asked is the unthinkable，"How old are you exactly"？
This question may result in a（an）（4）Alike："How old do you think I am？"Anyhow，if you are（5）B to know someone's age，first you estimate （估计） their age by their appearance．Then you take ten years away from that estimation．With a big（6）A，that person will probably say，'Thanks，but I am a few years older than that"．
Weight．This is one of the most sensitive subjects．In America，it is desirable to be thin but it is a huge （7）Dto be overweight．In any American fashion magazines，you'll notice most （8）D are nothing more than skin and bones．
Income．You should never ever ask how much someone's salary is．However，it's perfectly（9）Bto ask about their job title and what they do for a living．This information should give you some idea．
Matters of the Heart．This is a tricky （难处理的） one．Some people cannot wait to（10）Atheir hearts out to you．Then there are those who make sure their （11）C business stays behind closed doors．The general （12）B is not to get too personal．You don't want others to think that you are looking into their lives．Besides，try not to ask too many questions until you have a（n）（13）D with this person．

It is officially known as the Swiss Re Tower，or 30St Mary Axe．As a typical example of green architecture，what is most remarkable about the building is its energy-efficiency．（51）B its artful design and some fancy technology，it is expected to consume up to 50% less energy than a comparable conventional office building．Green architecture is （52）C the way buildings are designed，built and run．

4．We all have an idea about the common types of environmental problems．However，light pollution may he a（n）（41）B term to many of us．But，the fact is，it does（42）C mankind，other living forms and the environment as a whole．
Light pollution （43）A all forms of the misused man-made light．It is（44）D when artificial light sources brighten certain areas，which do not（45）C lighting．It can be office lighting，car（46）B，street lights and many more．
Light pollution is（47）D to both animals and human beings．Upon studies．obvious effects observed in the．（48）A of animals which are active at night．It is found that （49）Dlight at night makes it difficult for these animals to（50）C，wander and perform their regular activities As to human beings，light pollution is directly or indirectly（51）B for causing several diseases．Its effects are related to（52）A，in the body clock．It contributes to（53）D of developing cancerous cells．So，it's nothing less than a （54）B human health．
