3.Why is pink or purple a color for girls and blue or brown for boys?
The answer depends largely on cultural values as well as personal experiences.To the Egyptians,green is a color that means the hope and joy of spring,while for Muslims,it means heaven.Red stands for good luck in many cultures.In China,children are given money in a red envelope to bring good luck in the New Year.For many nations,blue stands for protection.Greek people often wear a blue necklace hoping to protect themselves from bad people or bad things happening.
People's choice of colors is also influenced by their bodies'reactions (反应) toward them.Green is said to be the most restful color.It has the ability to cut down pain and relax people both mentally and physically.People who work in green environment have been found to have fewer stomachaches.
Red can cause a person's blood pressure (血压) to rise and increase people's appetites (食欲).Many designers will include different shades of red in restaurants.Similarly,some websites will have a red"Buy Now"button because red is a color that easily catches a person's eyes.
Blue is another color which can make you feel peacefully.Unlike red,blue can cause people to lose appetite.So if you want to eat less,some suggest that eating from blue plates can help.
The next time you are deciding on what to wear or what color to decorate your room,think about the color carefully.

44.To the Egyptians,green meansB.
A.good luck

A.cause more stomachaches

C.cut down pain and relax people
D.make people's blood pressure rise

A.To help people relaxed.
B.To bring people good luck.
C.To make people feel peaceful.
D.To encourage people to buy the things.
47.What color might help lose weight according to the text?C

分析 文章介绍了为什么粉色或紫色代表女孩而蓝色或棕色代表男孩的由来.颜色的象征意思和文化以及个人经验有关,不同的文化对颜色的解读不一样.颜色的选择还和人们身体对它的反应有关,绿色最让人放松,有减轻疼痛的能力;红色可以让人血压升高增进食欲;蓝色可以让人平静,但会降低食欲.如果你想少吃点,不妨用蓝色的盘子装食物.

解答 44.B.细节理解题.根据To the Egyptians,green is a color that means the hope and joy of spring,可知,对于埃及人,绿色代表了希望和春天的喜悦,因此答案为B.joy of spring
45.C.细节理解题.根据第三段的内容,主要讲的就是绿色,根据Green is said to be the most restful color.It has the ability to cut down pain and relax people both mentally and physically.People who work in green environment have been found to have fewer stomachaches.可知,绿色能够减轻痛苦,使人在精神上和肉体上放松,在绿色环境中工作的人会少会胃疼,因此可知,绿色的主要作用就是减轻疼痛并使人放松,即C.cut down pain and relax people
46.D.细节理解题.根据buy now将定位于文章中的第四段,主要讲的是红色,根据Similarly,some websites will have a red"Buy Now"button because red is a color that easily catches a person's eyes.可知,一些网站立即购买按钮是红色的,原因是红色更吸引人的眼球,因此答案为D.To encourage people to buy the things.
47.C.细节理解题.根据倒数第二段So if you want to eat less,some suggest that eating from blue plates can help.可知,如果你希望吃的少一点,你可以选用蓝色的盘子,因此答案为C.Blue.

13.I was twenty years old,and my parents were looking forward to the day when I would be earning my own living.Unfortunately,I had absolutely no idea what I wanted my future occupation to be.The only thing I did know was that I did not want to spend the next 45 years teaching,being a nurse or sitting in an office.
But that was before the postman delivered a catalogue (目录) of courses that were being offered at the local college.As I looked through it,I was attracted by a page that talked about the difficulties faced by deaf people in their everyday lives and how students could help by learning sign language.It went on to say that graduates of the course usually find work in different organizations,such as law companies,the Stock Exchange,insurance companies and banks.Then I saw something that really caught my eye:"Singer"are also needed for sporting events,concerts,theatrical performances and,believe it or not,circuses!By the time I got to the bottom of the page,I knew I had found the perfect occupation.
I enrolled (注册) on the course,which to my parents'great delight was free of charge.The course was brilliant.My favourite part was the final lesson,when our teacher asked us to sign our favourite song.It was really difficult because not only did we have to sign the words,but we also had to find a way of showing whether the song was happy or sad and whether the beat was slow or fast.It was the hardest thing I have ever done-but also the most rewarding.
