分析 本文是关于健康习惯的调查.在一天刷几次牙,洗手沐浴几次,以及多久考虑过和细菌战斗一次等方面,描述了一些美国老年人的习惯并给出了专家建议.

解答 59.D.细节理解题.根据"A full 33% of seniors brush their teeth only once a day."可知大约三分之一的美国老年人一天只刷一次牙,故选D.
60.D.细节理解题.根据"And nearly 30% wash their hands only 4 times a day----half of the number doctors recommend."一天洗4次手是专家建议的一半,可知专家建议每天洗8次手.故答案选D.
61.C.细节理解题.根据"Do you know it is not your toilet but your kitchen sponge(海绵)that can carry more germs than anything else?"可知厨房里的海绵比任何其他东西(包括厕所)携带的细菌都多.所以C是正确的.
62.B.推理判断题.由文章内容可知,这是一份调查报告,是针对美国老年人的健康习惯所做的调查.这样的文章理应不会出现在"旅游指南""书评""官方文件"里,故排除 A、C、D.流行杂志做这样的调查报告很常见,故选 B.

点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.

8.A new study finds that our brains are wired to make music-color connections depending on how the music makes us feel.Mozart's"Flute Concerto No.1in G Major"is most often associated with bright yellow and orange,whereas his"Requiem in D Minor"is linked to bluish gray,the findings revealed.
US researchers from the University of California,Berkeley,enlisted nearly 100subjects for a study on music and color.With 37colors,the UC Berkeley study found that people tend to pair faster-paced music in a major key with lighter,more vivid,yellow colors,whereas slower-paced music in a minor key is more likely to be teamed up with darker,grayer,bluer colors.
"Surprisingly,we can predict with 95percent accuracy how happy or sad the colors people pick will be based on how happy or sad the music is that they are listening to,"said lead author and UC Berkeley vision scientist Stephen Palmer.
In three experiments,the subjects listened to 18classical music pieces that varied in pace (slow,medium,fast) and in major VS minor keys.In the first experiment,participants were asked to pick five of the 37colors that best matched the music to which they were listening.Separately,they rated each piece of music on a scale of happy to sad,strong to weak,lively to dull,and calm to angry.
Next,the research team plans to study particiapants in Turkey where traditional music employs a wider range of scales than just major and minor."We know that in Mexico and the US the responses are very similar,"Palmer said."But we don't yet know about China or Turkey."

8.What can we know about Mozart's"Flute Concerto No.1G Major"?A
A.It is fast in pace.
B It is slow in pace.
C.It makes us feel upset.
D It makes us feel optimistic.
9.What did the US researchers find from the result of the new study?D
A.There are colors that do not match any music.
B.People tend to connect happy colors to slow-paced music
C.There is a one-to-one connection between music and color.
D.People nearly do the same in picking colors for different music.
10.How did the researchers do the research?C
A.By making predictions.
B.By researching journals.
C.By conducting experiments.
D.By studying famous musicians.
11.According to the text,the research mainly deals withB
A.how colors or music influence our emotions
B.how emotions affect music-color connections
C.why we have different feelings towards music
D.why we have different feelings towards colors.

6.My mom just bought me a new bike.Since my cousin Mary didn't have a bike with her,she walked next to me.I thought that Mary would jump on the luggage carrier(行李架) over the back tire when I was riding.Mom knew exactly what I was thinking."Don't ride the bike with Mary on the back,"she said."It's too dangerous.You could kill yourself.Take turns."
I nodded,but I was thinking I could handle this.A few minutes later,I turned right to a wide road."Jump on the back,"I told Mary.I rode fast,laughing as the wind blew through our hair.It was exciting,until the handlebar(车把) started shaking.The front tire dropped into a drain (下水道) and I fell off the bike,still holding the handlebar.
My face,hands,and knees crashed into the pavement.The pain in my mouth was unbearable,and I tasted blood.I turned towards Mary who was on the ground,holding her knee and crying.Seconds later,it seemed that my mom's car stopped next to us.I wanted Mom to say,"Oh,my poor sweetheart.Let me hug you and everything will be fine."
However,my mom only said,"What have you done to your face?Vanessa,look at what you've done!"Mom wasn't the gentle"I love you,sweetie"type.
Sometimes,I thought Mom had no mercy.But in her own way,she was holding me tighter than I could understand-she was teaching me the lesson I needed."You did it-deal with it and learn from it.One day,the results will be greater and I won't be there to help you.Think it out,Vanessa."
