　　Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago. Post-it Notes--the pieces of paper that you can fasten almost any where and then remove without leaving any sign that they were there--are an example of such an invention.

　　Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Corporation. The idea for the product came from a frustrating(令人沮丧的)experience he often had while singing in his church choir(唱诗班). Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. He knew he needed a bookmark that would stay where he put it, but that he could remove without damaging the pages.

　　Around that time, Fry heard about a new adhesive(粘合剂) that a colleague(同行), Dr. Spence Silver, had created. This adhesive was special because it was sticky，but not too sticky. It was strong enough to hold papers together, but weak enough to not tear the paper when it was removed. Fry saw that the new adhesive could help solve his bookmark problem. One morning, Fry put some of the adhesive on the edge of a piece of paper. Just as he hoped, it made a perfect bookmark.

　　A short time later, Fry realized that his new invention had even more uses than being a great bookmark. He came to this realization when he wrote a note on one of his new“bookmarks”and attached(附着)it to a report he was going to give to a colleague. Soon, co-workers were asking Fry for more samples(样品)of his invention so that they could use the new type of notes themselves.

　　Fry and some other people at 3 M believed so much in the new product that they persuaded the company to give away thousands of the“sticky pieces of paper”for trial use. When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off.

1．The invention of Post-it Notes showed that Art Fry _____.

[　　]

A．had a lot of knowledge

B．was very hard-working

C．was good at creative(创造性的)thinking

D．loved his job in the church

2．In what way did Dr. Spence help Art Fry?

[　　]

A．They worked together and often discussed science.

B．His invention of a special adhesive made Art's invention possible.

C．He persuaded 3M Corporation to give away lots of Post-it Notes for trial use.

D．He cooperated with Art by providing the new adhesive for Art.

3．Which of the following is a possible use of Post-it Notes?

[　　]

A．A note on a friend's door.

B．An e-mail to a friend.

C．A postcard from abroad.

D．An ad in a newspaper.

42The underlined phrase“took off”means _____.

[　　]

A．started to leave the ground

B．disappeared from the market

C．had even more uses

D．became popular very quickly

　　Even nowadays there’s a lot of misunderstandings between nationalities．

　　Let’s have a look at what the following people have to say．

　　Maria Conti：I find the English people insincere(虚伪的), cold and unfriendly．They keep saying “Thank you”, “I’m sorry”, even when they don’t know each other．They are even polite to their own relatives!Except for helping you find your way in the streets, they aren’t really friendly and never invite you to their house．

　　Giannis Sinios：On the contrary I found them both broad-minded and friendly．I was invited to people’s houses and they all showed great interest in my ideas, Greek life and people．In England I learned that it was possible to be warm, friendly and polite at the same time．

　　That “Monday morning feeling” could be a crushing pain in the chest which leaves you sweating and gasping for breath．Recent research from Germany and Italy shows that heart attacks are more common on Monday mornings and doctors blame the stress of returning to work after the weekend break．

　　The risk of having a heart attack on any given day should be one in seven, but a six year study helped by researchers at the Free University of Berlin of more than 2600 Germans showed that the average person had a 20 percent higher chance of having a heart attack on a Monday than on any other day．

　　Working Germans are particularly not protected against attack, with a 33 percent higher risk at the beginning of the working week．Non-workers, by comparison, appear to be no more at risk on a Monday than any other day．

　　A study of 11 000 Italians proved 8 a. m. on a Monday morning as the most stressful time for the heart, and both studies showed that Sunday is the least stressful day, with fewest heart attacks in both countries．

　　The finding could lead to a better understanding of what is the immediate cause of heart attacks, according to Dr．Stefan Willich of the Free University．“We know a lot about long term risk factors such as smoking and cholesterol(胆固醇)but we don’t know what actually causes heart attacks, so we can’t give clear advice on how to prevent them.” he said．

　　Monday mornings have a double helping of stress for the working body as it makes a rapid change from sleep to activity and from the relaxing weekend to the pressures of work．

　　“When people get up, their blood pressure and heart rate go up and there are hormonal(荷尔蒙)changes in their bodies,” Willich explained．“All these things can have an unfavorable effect in the blood system and increase the risk of a clot(血凝块)which will cause a heart attack．”

　　“When people return to work after a weekend off, the pace of their life changes．They have a higher workload, more stress, more anger and more physical activities,” said Willich．

(1)

Monday morning feeling, as this passage shows, ________．
[　　]
A．	is not as serious as people thought
B．	is the first killer in Germany and Italy
C．	is created by researchers in Germany and Italy
D．	is harmful to working people in developed countries

(2)

To protect people from a heart attack, doctors have paid much attention to ________．
[　　]
A．	people’s working time
B．	people’s living place
C．	people’s diet and lifestyle
D．	people’s nationalities

(3)

It can be learned from the passage that the heart attack has something to do with all the following EXCEPT ________．
[　　]
A．	blood pressure
B．	heart rate
C．	hormonal changes
D．	blood type

(4)

If the researchers give us some advice to avoid Monday morning feeling, what might it be?
[　　]
A．	Improve working conditions．
B．	Never go to work on Mondays．
C．	Stay with a doctor on Mondays．
D．	Get up late on Monday mornings．

　　On the first day of school we were challenged to get to know a new classmate．I was looking around, when a gentle hand touched my shoulder．I found a little old lady with a warm smile．

　　She said, “Hi, handsome! I'm Rose．I'm 87 years old．Can I give you a hug(拥抱)?” I laughed and heartily responded, “Of course!”

　　“Why are you in college at such a young, innocent(天真的)age?” I asked．

　　She jokingly replied, “I'm here to meet a rich husband, get married, have children, and then travel around．”

　　“No, seriously,” I asked．I was curious why she took on this challenge at this age．

　　“I always dreamed of having a college education and now I'm getting one!” She told me．We became instant friends．

　　“There is a huge difference between growing older and growing up．Anybody can grow older．That doesn't take any talent or ability,” she added．“But growing up requires finding the opportunity in change．The elderly usually don't have regrets for what they did, but rather for things they did not do．”
