During my high school years, the most important thing was what I was wearing to the Friday night dance and who I was taking. Although college was talked about, it was the least of my worries.
When I was graduating eighth grade and starting high school, my older brother was graduating twelfth grade and going onto college. For my graduation, he gave me a card in which he wrote, “Enjoy your four years…, they go by fast.” I remember not believe him then, but looking back…, he was right. Those four years shaped who I was as a person, pushed me to my limit and encouraged me to become an adult.
However, I was so completely absorbed in my junior and senior years of high school, that when someone spoke of college I brushed it off. I wasn't ready to leave my comfort zone of having all of my closest friends together and knowing what every single day was going to be like . Studying was something I did only AFTER I nailed my half-time dance performance. I knew my parents wanted me to go to college, so I told them I would go to commuity college (社区学院)and I didn’t worry about my SAT（美国大学入学考试）scores.
When my senior year passed and everyone graduated and went off to their own college ,I started to wish I had done the same. My friends were living away, meeting new people, discovering new places, and I was living at home and driving to and from class every day. It seemed exactly like high school. I hated it! I thought college was supposed to be different! Why didn’t I take more time to research colleges and do the same? I ended up loving college and wishing I had four years to enjoy the campus(大学校园)atmosphere instead of two.
My advice to anyone thinking about attending college is to think about it very seriously and look into all of your choices well ahead of time. Now I have graduate and I am working full time and I would do anything to go back to my high school days for a second chance!

【推荐2】Ungraded question, posted by Instructor, Dr Green
In next week's lecture, we will be discussing identity. Social experts suggest that we have three basic types of identity. First, your given identity includes your gender(性别), your birthplace, and your age. These are aspects of identity that are almost impossible to change. Second is your chosen identity, groups you choose to become a part of. Chosen identity can include your beliefs, your professions(
职业), or your community organizations. Finally, your core identity is what makes you unique. Your behaviors, personality, values, and skills are all part of your core identity. Before Monday's lecture post a short reply to this question.
QUESTION: How has your identity changed in the last few years, including the three aspects of identity?
Posted by Ali K.
When I started high school, I thought that I knew exactly who I was and where I was headed. I was a star soccer player, and my entire identity was soccer-I lived it and breathed it. This was my chosen identity. Everything changed when l had a terrible knee injury during my second year. After several months, it was clear that I wouldn't be able to play soccer competitively again. I felt really sad when I had to quit the team, and I was very unhappy. Slowly I started to see that I was still the same
person on the inside. I was still a very hard-working person, someone who didn't easily give up, and someone who loved being on a team. These were part of my core identity. I had to rediscover my values (hard work and competition) to get me through this hard time. I've been developing a new sense of identity. Although I've had to change part of my chosen identity, I now understand that my core identity (who I am inside) is the most important for me.

Like Ali, I had a very hard time in high school. I felt like my parents didn't understand or respect me, and nothing I did was right in their eyes. ① They didn't think I was trustworthy, and I admit that sometimes l didn't make great choices. But my parents are part of my given identity, and therefore they are very important in my life. During high school, my chosen identity was the group of friends that I belonged to. ② However, some friends were influencing me in bad ways. I felt really lost and unhappy with my life. Later, when I started at the university in my city, I decided to find some new friends. ③ Now I can realize the changes in me and feel more comfortable around my parents because they respect me as an adult. ④ It is important to remember that your chosen identity is not who you are. You can make other choices, and change your life.

Sitting in a dark movie theater with your friends and a tub ofbuttery popcorn sounds like a perfect way to spend a Saturday night
—and it could be, if you are willing to share your popcorn with the
entire row of moviegoers around you.
A review of the nutritional contents of movie-theater popcorn reveals
an alarming amount of fat, salt and calories in even the smallest sizes.
The study, mad by Dr. Nestle from the Center for Science in the Public
Interest, checked popcorn from three movie theater chains and detailed
The contents of all parts offered.
A large tub of popcorn at Regal Cinemas, for example, holds 20 cups of popcorn and has 1,200 calories, 980 milligrams of sodium（钠）and 60 grams of saturated（饱和）fat.
Not so hungry? The medium size popcorn, which comes in a bag, contains the same amount as the large. And even the small, at 1l cups, delivers 670 calories 550 milligranis of sodium 24 grams of saturated fat.
The findings may surprise those who choose popcorn at the concession stand（货摊） because they believe it is a relatively healthy snack. In fact, plain air-popped popcorn is low in calories and free of saturated fat. Movie theater popcorn, however, is popcorn, however, is popped in oil — often coconut oil, which is 90 percent saturated fat. Add salt to the enormous portions（部分）,and your once-healthy snack turns into a health killer.
Even the “healthiest” sample of popcorn tested, a small size from AMC containing 6 cups of popcorn, had 370 calories, enough to share with a friend, eating one grain at a time to make it last the length of a movie.
The third movie theater chain tested. Cinemark, is slightly better than its competitors because it pops its popcorn in non-hydrogenated canola oil instead of coconut oil. Cinemark’s large tub contains 17 cups of popcorn with 910 calories and 4 grams of saturated fat, as well as up to 1,500 milligrams of sodium — nearly enough for the entire day.
One way to make your popcorn healthier? Ask the theater to pop a portion without salt. Two of the movie theaters that had their popcorn tested said they would oblige such a request. The best way to make your movie snack healthier, however, would be to skip the popcorn — and the concession stand — altogether.
“You could share a tub of popcorn with 10 friends.” Dr. Nestle said. “Or, what a concept, watch the movie without eating anything.” K^S*5U.C#O

【推荐1】In the UK, most children have their midday meal at school, but in many schools, parents can choose what their children eat. The children can have a school lunch—a hot, cooked meal; or they can take a packed lunch with them, which usually includes cold food like sandwiches.
Often parents prepare lunches on the basis of what their children want. Cathy, a mother of three children, told us, “My children have packed lunches, because they say they hate school dinners. I make 3 packed lunches every morning, so we’re like a sandwich bar in our kitchen in the morning.”
However, another mother, Susan, made her choice based on the nutritious value of the food. She said, “My daughter always has school dinners. I think she probably gets healthier food by having a cooked lunch at school than she would if I made sandwiches.”
But how healthy are school dinners? Kaz, a father, wasn’t impressed with them. “Fizzy (有泡沫的) drinks were offered and I think there were a lot of chips.”
The question of how healthy school food is was brought to Jamie Oliver, who launched a campaign to improve children’s nutrition, after spending a year working in a school kitchen. The TV series about the campaign won an award this week.
He was horrified (惊恐的) at the junk food he saw being served, which included burgers, pizza and chips. He decided to ban the junk, and started cooking good stews (炖菜) and curries for the children instead.
Jamie improved the school dinners in that particular school, and trained the dinner ladies to cook healthy food. Then he put pressure on the government to improve the standards of school food across the country. And it looks as if the changes have begun.

Office calls are, perhaps, the most difficult and the most important part of a secretary's work．The first impression that a man receives about a business is often through a telephone contact．A caller who is left hanging on “hold” will get the feeling that he or she has been forgotten or ignored．If a call is answered rudely, the caller may become angry．And if the call is not routed directly to the right person, the caller may feel that he or she is getting the “run-around”.
Laura Needham is a secretary in the executive offices of a large manufacturing company．As a good office secretary, Laura knows that all phone calls must be answered without delay and handled efficiently. She knows that a secretary must be pleasant and helpful, no matter how busy she is or what kind of feeding she may be in．She knows she must keep calm if a caller gets impatient or becomes angry; also, of course, she knows she can never allow herself to lose her temper (脾气)．If she does not have the information the caller asks for, she must know who does have the information．Finally, she knows that one of her most important responsibilities(责任)is to “screen telephone calls” and to know which calls to refer to her boss, which calls to refer to other people, and which calls to handle herself．
A well-handled telephone call will give the caller a good impression of the company he or she is dealing with．For this reason, an office secretary who can handle telephone calls cheerfully, tactfully (老练的), and efficiently is a valuable asset to any organization

This year, a very sweet old lady that I cared for, Alice, had gone through a difficult time. She got dementia and so she had been in the hospital twice. In November I was finally able to get her back to her “home”.
Alice had thought her daughter was coming to visit her on Christmas day and that they were going to have the whole family together like the old days. When she finally realized that that happy moment was not going to happen, she was very sad. Knowing that her daughter was coming after Christmas was not enough to make her feel happy, I hated the idea of her being alone on the holiday!
On Christmas Eve, I gave her a surprise by asking if she would like to go to a candlelight service at church that night.
Instead of taking her to my church, I took her to her old neighborhood church where all her friends were. We got there early and I got her a seat where her friends could see her as they came in. Then soon some of her friends came to the church and they rushed over to greet her and sit with her.
The candlelight service was beautiful and Alice got a lot of love from her old and new friends there.
The truth of the story is that I am the one who got the best gift: the smile on Alice’s face.

阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项，并在答题卡上将该项涂黑。
A
1685 was a very good year for German composers. Within the space of a month, two of the greatest were born: Johann Sebastian Bach and George Frederic Handel.
Handel’s father was a barber and surgeon, which sounds like a strange combination today, but back then those occupations went hand in hand. Even though Handel was very interested in music, his father didn’t think that was a good way to earn a living, so he wanted his son to be a lawyer. The story goes that Handel smuggled a quiet piano into the house so that he could practise in secret.
One day, Handel went along when his father went to shave a duke. While his father was working, Handel sat down and played the duke’s organ. The duke was so impressed that he convinced Handel’s father to let his son study music, and Handel finally got to learn how to compose.
Handel soon discovered that what he liked most was opera. In fact, he was so passionate about opera that he even fought a duel (决斗) over it with one of his friends. Since Italy was the place to learn about opera composing, Handel went off to Italy to study. When he got home, he got a job as court composer for a German prince.
Having landed such a wonderful job, Handel immediately asked his boss for time off. He wanted to go to England, where he’d heard that there weren’t nearly enough composers to satisfy the British taste for Italian opera.
After great success writing opera in London, Handel came back to Germany. Then fate played a funny trick on Handel and his boss. The Queen of England died, and it just so happened that the prince Handel worked for was next in line to the British throne. When he arrived in London as King George, followed Handel, his court composer in Germany.
In addition to serving the King, Handel became one of the most successful opera composers of his time. And he also produced them and traveled all over Europe to hire the best singers. There are stories of battles with rival opera producers and of fights between rival singers. Handel apparently had quite a temper.
If you ever go to London, look for Handel’s grave in Westminster Abbey, where there’s a wonderful monument to him.
1. How did Handel begin to learn to compose?
| A．His father was sure of his future success. |
| B．His performance impressed a duke. |
| C．He begged his father to send him to Italy. |

| C．Because his boss became King of Britain and brought him along. |
| D．Because London was a wonderful place to learn about opera. |
| A．bad-tempered | B．talented | C．enthusiastic | D．optimistic |
| A．Handel was born in the same year with Bach. |
| B．Many people worked both as a barber and surgeon. |
| C．Handel quit his job to learn about opera in Italy. Handel was buried in London and was built a monument. |

The thing is, my luck’s always been ruined. Just look at my name: Jean. Not Jean Marie, or Jeanine, or Jeanette, or even Jeanne. Just Jean. Did you know in France, they name boys Jean? It’s French for John. And okay, I don’t live in France. But still, I’m basically a girl named John. If I lived in France, anyway.
This is the kind of luck I’ve had since before Mom even filled out my birth certificate. So it wasn’t any big surprise to me when the cab driver didn’t help me with my suitcase. I’d already had to tolerate arriving at the airport to find no one there to greet me, and then got no answer to my many phone calls, asking where my aunt and uncle were. Did they not want me after all? Had they changed their minds? Had they heard about my bad luck—all the way from Iowa—and decided they didn’t want any of it to rub off on them?
So when the cab driver, instead of getting out and helping me with my bags, just pushed a little button so that the trunk (汽车后备箱) popped open a few inches, it wasn’t the worst thing that had ever happened to me. It wasn’t even the worst thing that had happened to me that day.
According to my mom, most brownstones in New York City were originally single-family homes when they were built way back in the 1800s. But now they’ve been divided up into apartments, so that there’s one—or sometimes even two or more families—per floor.
Not Mom’s sister Evelyn’s brownstone, though. Aunt Evelyn and Uncle Ted Gardiner own all four floors of their brownstone. That’s practically one floor per person, since Aunt Evelyn and Uncle Ted only have three kids, my cousins Tory, Teddy, and Alice.
Back home, we just have two floors, but there are seven people living on them. And only one bathroom. Not that I’m complaining. Still, ever since my sister Courtney discovered blow-outs, it’s been pretty frightful at home.
But as tall as my aunt and uncle’s house was, it was really narrow—just three windows across. Still, it was a very pretty townhouse, painted gray. The door was a bright, cheerful yellow. There were yellow flower boxes along the base of each window, flower boxes from which bright red—and obviously newly planted, since it was only the middle of April, and not quite warm enough for them.
It was nice to know that, even in a sophisticated (世故的) city like New York, people still realized how homey and welcoming a box of flowers could be. The sight of those flowers cheered me up a little.
Like maybe Aunt Evelyn and Uncle Ted just forgot I was arriving today, and hadn’t deliberately failed to meet me at the airport because they’d changed their minds about letting me come to stay.
Like everything was going to be all right, after all.
Yeah. With my luck, probably not.
I started up the steps to the front door of 326 East Sixty-Ninth Street, then realized I couldn’t make it with both bags and my violin. Leaving one bag on the sidewalk, I dragged the other up the steps with me. Maybe I took the steps a little too fast, since I nearly tripped and fell flat on my face on the sidewalk. I managed to catch myself at the last moment by grabbing some of the fence the gardeners had put up…

【推荐2】Every night for a year, Neil Simons quietly went out of his house. He wanted to “talk” to an owl (猫头鹰)settling for the night at the end of his garden. He made owl cries like a real wild owl and was happy to hear the bird “hooting (大声叫嚣)” back to him.
Last year Fred Cornes moved in next door. He heard an owl hooting and answered back. For 12 months the neighbors got into the back gardens of their homes, thinking they were talking with nature. Mr. Simmons kept a diary of all his talks with his bird friend. They would both be out again tonight if it wasn’t for a chance talk between their wives.
Mr. Simmons said. “My wife Kim was telling Fred’s wife Wendy about my owl watching and described how I got the birds to boot back. She said, ‘That’s funny — that’s just what Fred has been doing.’ Then the penny dropped, I felt such a fool when I found out. The trouble is that owl calls aren’t exactly the same and it’s easy to make a mistake.”
Mr. Cornes said, “I’m really flattered (过奖). I didn’t know I sounded so real. I love nature and I couldn’t resist hooting at the owls. I was very excited when they hooted back. I’m sorry that I was fooling my neighbor who was fooling me.”

The 10－to－12－year－old girls found out where beavers lived, set traps, and skinned the two animals they caught. The girls hope to catch ten more beavers so that the entire troop can make mittens and hats with the fur. They also want to cook beaver meat.
Troop leaders and members say the Scouts are doing a good deed by helping control the state’s beaver population. But animal－rights activists say trapping is cruel. They want the Girl Scouts to stop in their tracks.
Beavers aren’t only causing a problem in Alaska. Residents in Sampson County, N.C. , have turned to a local committee to help them battle the growing beaver population there.
County landowners are frustrated after the county spent more than $ 50,000 in eight years trying to reduce the beaver population through a government program. The joint state and federal program included paying money to trappers for every beaver carcass they trapped.
Many local residents say that the program didn’t work because there were too few trappers. That’s why the county set up its own committee to investigate other ways to control the area’s beaver population.
The county will rely on its own beaver－trapping program. It has hired a trapper to set traps in various areas. The county will pay $10 for every beaver carcass.
Why do many people say that beavers are a nuisance? For beavers to survive, they need lots of water. Water provides the large rodent （啮齿动物）with a place to hide from meat – eating animals. Beavers also store food underwater for the winter. When there’s not enough water in a particular area, beavers get busy building dams.
Beaver dams can cause major flooding and damage to the surrounding countryside as the animals cut down trees to use in their construction projects. Beavers build canals to transport heavy objects.
