Since most important problems are multifaceted(多方面的),there are several alternatives to choose from,each with unique advantages and disadvantages.One of the benefits of a pencil and paper decisionmaking procedure is that it permits people to deal with more variables(可变因素) than their minds can generally comprehend and remember.On average,people can keep about seven ideas in their minds at once.A worksheet can be especially useful when the decision involves a large number of variables with complex relationships.A realistic example for many college students is the question “What will I do after graduation?”A graduate might seek a position that offers specialized training,pursue an advanced degree,or travel abroad for a year. A decisionmaking worksheet begins with a statement of the problem that will also help to narrow it.It is important to be clear about the distinction between longrange and immediate goals,because longrange goals often involve a different decision than shortrange ones.Focusing on longrange goals,a graduating student might revise the question above to “What will I do after graduation that will lead to successful career?” 1.In Paragraph 1,the author develops the discussion by means of . A.describing a process B.classifying types of worksheets C.providing historical background D.explaining a theory 答案 A 解析 推理判断题。第一段先介绍了决策工作表,然后陈述了决策工作表的制订过程,因此选A。 2.Which of the following steps occurs before the others when making a decision worksheet? A.Deciding which consequences are the most important. B.Calculating a numerical summary of each solution. C.Listing the consequences of each solution. D.Writing down all possible solutions. 答案 D 解析 细节理解题。根据第一段第五句“Worksheets require defining the problem in a clear way and then listing all possible solutions to the problem.Next...”可知,制订决策工作表的第一步是定义问题并列举所有解决问题的办法,故应选D。 3.According to decisionworksheet theory,the best choice is defined as the one . A.that has the most points assigned to it B.that uses the most decision worksheets C.that has the fewest variables to consider D.that is agreed to by the greatest number of people 答案 A 解析 推理判断题。根据第一段最后三句“Each consideration is assigned a numerical(数字的)...comes as the best decision.”可知,把所有这些数值相加就能以数学方法来衡量一个决定,得分最高的决定就是最佳决定。 4.The underlined word “revise” in the last paragraph is closest in meaning to “ ”. A.ask B.explain C.change D.predict 答案 C 解析 词义猜测题。根据最后一段第二句“...because longrange goals often involve a different decision than shortrange ones.”可知,如果侧重于长期目标,毕业生可能会修改上述问题,从而做出不同的决定,因此该词意思为“改变,修改”。 B Beat the heat:Peppermint tea mist(薄荷茶喷雾) Boil a pot of peppermint tea,then put it in the fridge. Once it’s nice and cold,Wonderhowto.com suggests pouring some into a spray bottle and misting yourself with it.Better than water,the menthol(薄荷醇) in the tea will give your skin a cool feeling. Beat the heat:Chrysanthemum tea (菊花茶) Whether it’s hot or cold,chrysanthemum tea is served to lower body temperature,according to China Daily. Beat the heat:Chill your mattress(床垫) Put soft ice packs on top of the mattress and underneath the sheets;try under your legs,neck,or lower back for comfort.Real Simple also suggests freezing a cotton sock filled with rice,then slipping it between the sheets.The rice will hold a chill longer. Beat the heat:Aloe vera(芦荟) You know aloe vera soothes sunburn,and its cooling features also work to help you beat the heat. Beat the heat:Spicy(辛辣的) food If you’re already sweating,why would you want to sweat more?Professor of food science at Penn State University Luke LaBorde offers this answer:eating spicy food increases blood circulation and makes you sweat,so you’ll feel cooler as the sweat dries.He explains that the capsaicin (辣椒素) in hot peppers encourages your body to sweat more without raising your body temperature. Beat the heat:Pressure parts Lifehacker.com’s solution to lower body temperature is to apply a bottle with icecold water on points like your ankles,wrists,or behind the knees. Chill your bed by folding sheets and pillowcases,placing them in plastic bags,and sticking them in the freezer for a few hours,according to Mother Nature Network.Then make up the bed just before you go to sleep for sweet (and cool) dreams. When all else fails,take frequent cool showers to keep your body temperature down and get rid of the sweat. 5.How many ways are mentioned in the passage? A.Five. B.Six. C.Seven. D.Eight. 答案 D 解析 细节理解题。全文重点通过六个小标题介绍了六种消暑降温的方法,文章最后两段又分别介绍了两种方法,所以一共有八种方法。 6.It can be learned from the passage that . A.Wonderhowto.com suggests we can mist ourselves with icecold water to lower body temperature B.we can probably cool off by taking cool showers if other approaches don’t work C.only by making the bed before going to bed can one dream a sweet dream D.aloe vera only cools down sunburn,but can’t help one beat the heat 答案 B 解析 细节理解题。根据文章最后一句可知答案为B。其他选项均是对文章的错误理解。 7.What good advice does Luke LaBorde give if someone wants to sweat more? A.Eating spicy food. B.Misting with peppermint tea. C.Drinking more tea. D.Using aloe vera. 答案 A 解析 细节理解题。根据Beat the heat:Spicy(辛辣的)food部分中的“Professor of food science at Penn State University Luke LaBorde offers this answer:eating spicy food...”可知答案为A。 8.According to this passage,which of the following statements is FALSE? A.Chrysanthemum tea is useful to lower body temperature. B.Freezing a cotton sock filled with rice will keep a chill longer. C.The menthol in the tea will give your skin a cool feeling. D.Aloe vera can kill the heat only if you drink as much as possible. 答案 D 解析 细节理解题。A项与“chrysanthemum tea is served to lower body temperature”一致;B项与“The rice will hold a chill longer.”一致;C项与“the menthol(薄荷醇)in the tea will give your skin a cool feeling.”一致;而D项中的only if从句为错误添加信息,其在文中并没有涉及。 Ⅱ.阅读填空 How to make friends at a new school You’re about to start a new school and want to make friends there.What do you do?Here are some tips on how to meet people and make friends at a new school and how to adjust to your new surroundings. 9 There’s nothing that attracts people more than someone who’s secure in who they are and has a fairly positive attitude about life in general and other people’s ideas,too.
