10.Food production does great harm to our environment.There are many procedures involved in the manufacture of food that result in greenhouse gases and other pollutants.Some procedures require the consumption of large amounts of fossil fuels,such as the transportation and storage of food products.Other factors that cause great damage to our environment include the overuse of fresh water.
    The production of beef is more damaging to the environment than that of any other food we consume,Raising large numbers of cattle requires the production of large amounts of food for the animals.It's estimated that producing one pound of beef requires seven pounds of feed.
    Land use is also a problem.If the cattle are free-range cattle,large areas of land are required for them to live on.This has led to disastrous forest cutting and the loss of rare plants and animal species,particularly in tropical rain forests in Central and South America.
    Another problem specific to beef production is methane emissions(甲烷排放).Although many people are aware of the damaging effects of carbon dioxide,they don't realize methane's global warming potential is 25times worse,making it a more dire problem.
    Unfortunately,beef consumption is growing rapidly.This is the result of simple supply and demand factors.Specifically,there are two main causes of demand that are encouraging the production of more supply.First,the increase in the world population means there are more people to consume meat.The second factor is socioeconomic advancement.As citizens in developing nations become financially stable,they can afford to buy more meat.
    Therefore,one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.

32.Which of the following is TRUE?C
A.Raising free-range cattle is eco-friendly.
B.People cut down trees for animal habitats.
C.Producing beef can damage the environment.
D.Carbon dioxide causes far more harm than methane.
33.The underlined word"dire"in Para.4 meansA.
A.urgent  B.common  C.typical  D.avoidable
34.Beef production is growing rapidly becauseA.
A.more people are in demand of beef
B.developing countries raise more cattle
C.more land is available to raise cattle
D.the cost of raising cattle is relatively low
35.The author writes this article toD.
A.describe the booming of the beef production
B.emphasize the advantages of beef production
C.condemn the deforestation of the rain forest
D.argue for a decrease in beef consumption.

分析 本文讲述了生产牛肉给环境带来的危害,希望可以使人们降低牛肉的消费.

解答 32.C.细节理解题.由第二段The production of beef is more damaging to the environment than that of any other food we consume可知,生产牛肉特别损害环境,故选C.
33.A.词义猜测题.由前一句Although many people are aware of the damaging effects of carbon dioxide,they don't realize methane's global warming potential is 25times worse,虽然很多人都知道二氧化碳的破坏性影响,但是他们没有意识到甲烷的全球变暖潜能是二氧化碳的25倍,这是一个更可怕的事情,故选A.
34.A.细节理解题.由倒数第二段the increase in the world population means there are more people to consume meat,可知人口的增长导致需要更多的牛肉,故选A.
35.D.主旨归纳题.由最后一段one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.可知作者希望可以使人们降低牛肉的消费来减少温室气体排放,故选D.

点评 本篇文章主要是细节理解方面的题型,需要考生通过跳读迅速找到对应的句子进行详细理解,句子的理解可以结合上下文意思,通过逻辑推理得到.

20.Wealth starts with a goal and saving a dollar at a time.Call it the piggy bank plan.There are lessons in that historic coin-savings container (容器).
Any difficult task seems easier when started from baby steps.If you wished to climb a 12,000-foot mountain,and could do it a day at a time,you would only have to climb 33 feet daily to reach the top in a year.If you want to take a really nice trip,to collect the 15,000cost,you have to save 3.93 a day.If you drop that into a piggy bank and then once a year put $1,434 in a savings account,you will have your trip money.
When I was a child,my parents gave me a piggy bank to teach me that,if I wanted something,I should save money to buy it.We connect piggy banks with children,but in many countries,the little containers are also popular with adults.Europeans see a piggy bank as a sign of being rich.Around the world,many believe a gift of a piggy bank on New Year's Day brings good luck and wealth.
Why is a pig used as a symbol of saving?Why not an elephant bank,which is bigger and holds more coins?In the Middle Ages,before modern banking,skillful workers made these inexpensive containers from an orange-colored clay (黏土)called"pygg,"and people then saved coins in pygg jars.As"pygg"pronounced much like the Middle English word"pigge"meaning"pig",gradually,the two words changed into the same pronunciation.Once a clever worker made a pygg jar in the shape of a pig,pleasing children and adults.The piggy bank was born.
In the past,you had to break the bank to get the money,bringing in a sense of seriousness into savings.While piggy banks teach children the value of saving,adults often need to relearn childhood lessons.Think about the things in life that need a large sum of money-college education,weddings,starting a business,buying a home,and fun things like great trips.So when you have money,take off the top 10%,put it aside,save and use it wisely.

A.Setting a goal before making a travel plan.
B.Putting aside a little money regularly for future use.
C.Hav ing determination even when doing small things.
D.Climbing a mountain a little a day before reaching the top.
30.Why did the writer's parents give him a piggy bank as a gift?A
A.To help him develop the habit of saving.
B.To encourage him to climb mountains.
C.To please him with the latest fashion.
D.To teach him English pronunciation.
31.The piggy bank was firstD.

C.an animal-look dish                       
D.a cheap clay container
