Some people will do just about anything to save money. And I am one of them .Take my family's last vacation for example .It was my six-year-old son's winter break form school ,and we were heading home form Fort Lauderdale after a weeklong trip. The flight was overbooked ,and Delta , the airline ,offered us $400 per person in credits(积分) to give up our seats and leave the next day .I had a meeting in New York，So I had to get back . But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.

    The next day my husband and son were offered more credits to take an even later flight.Yes, I encouraged一okay, ordered-them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh?

    Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal(交易) is something few of us can afford to pass up.

    I've made a living looking for the best deals and exposing the worst tricks .I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple

    of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do  what I believe in.

    I tell you this because there is no shame in getting your money's worth. I'm also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate (犹豫)to spend on a good haircut. It keeps it longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.

    Many Americans spend more time in cars these days than in the kitchen. But as lives grow busier—and waistlines grow larger—a number of health experts are calling for Americans to reduce their risk of cancer and other diseases by cooking at home more and eating out less.

    “When dining out, people are likely to gravitate towards all the wrong thing,” says Rachel Brandeis of the American Dietetic Association. “People take in 50% more fat and sodium when they eat out than when they cook at home. And they often miss out on fruits, vegetables and other vitamin-rich ‘powerhouse foods' that may reduce the risk of cancer.”

    Nutritionists know it's not easy to break old habits. Many people say they hardly have time to exercise, let alone fix dinner.

    Brandeis says her secret is organization. She cooks six nights a week, even though she and her husband both work. She spends 20 minutes thinking about a week's worth of menus and writing a list. She shops just once a week. Brandeis says she chooses easy cooking methods, too. Since she is not quite good at cooking.

    The American Institute for Cancer Research has produced a guide filled with tips like “Homemade for Health”. Melanie Polk, the institute's director of nutrition education, says cooking at home has many advantages. It teaches children about nutrition as well as the importance of sharing housework.

    The 39-year-old homemaker Kirstin Kristinus of Washington, D.C. says cooking at home brings her family together. She also tries to reduce her family's cancer risk by preparing every meal with many different kinds of food.

    “The only way to know that you are getting all the good things is to expose yourself to a wide variety of food,” says Steven Shiff, a doctor in New Jersey. “If you eat out at a restaurant, it's a lot easier to choose unhealthful things.”

    However, “families don't have to give up restaurants,” Shiff says. “It is possible to eat healthfully if you eat outside the home. But it takes probably the same sort of planning that you would have to do to prepare meals at home.”

    Mothers and daughters go through so much—yet when was the last time a mother and daughter sat down to write a book together about it all? Perri Klass and her mother, Sheila Solomon Klass, both gifted professional writers, prove to be ideal co-writers as they examine their decades of motherhood, daughterhood, and the wonderful ways their lives have overlapped (重叠).

    Perri notes with amazement how closely her own life has mirrored her mother's: both have full-time careers； both have published books, articles, and stories； each has three children； they both love to read. They also love to travel—in fact, they often take trips together. But in truth, the harder they look at their lives, the more they acknowledge their big differences in circumstance and basic nature.

    A child of the Depression (大萧条), Sheila was raised in Brooklyn by parents who considered education a luxury for girls. Starting with her college education, she has fought for everything she's ever accomplished. Perri, on the other hand, grew up privileged in the New Jersey suburbs of the 1960s and 1970s. For Sheila, wasting time or money is a crime, and luxury is unthinkable while Perri enjoys the occasional small luxury, but has not been successful at trying to persuade her mother into enjoying even the tiniest thing she likes.

    Each writing in her own unmistakable voice, Perri and Sheila take turns exploring the joys and pains, the love and bitterness, the minor troubles and lasting respect that have always bonded them together. Sheila describes the adventure of giving birth to Perri in a tiny town in Trinidad where her husband was doing research fieldwork. Perri admits that she can't sort out all the mess in the households, even though she knows it drives her mother crazy. Together they compare thoughts on bringing up children and working, admit long-hidden sorrows, and enjoy precious memories.

    Looking deep into the lives they have lived separately and together, Perri and Sheila tell their mother-daughter story with honesty, humor, enthusiasm, and admiration for each other. A written account in two voices, Every Mother Is a Daughter is a duet (二重奏) that produces a deep, strong sound with the experiences that all mothers and daughters will recognize.

    New Orleans native Keiana Cave, at the age of 18, is one of the youngest Americans named in the 2017 Forbes 30 Under 30 list. The college girl developed a molecule(分子) for dispersing (分解) oil, which she presently produces through her company Mare.

    Forbes, one of the most popular magazines in the US, released its annual 30 Under 30 lists on January 3, 2017. With 20 different categories (类别) from music to law and policy, in each area. Forbes presented 30 up-and-coming young groundbreakers (创始者) on its official website.

    Cave is comparatively much younger than those selected to her category, but this by no means discounts her exceptional ability. To  see her daughter's name on the list, Vanessa Cave-Herazo was surprised, but she said she knew it was coming because “Keiana has always been destined(注定) for great things.

    After learning about the negative effects of the oil dispersant( 分散剂) used in the Gulf Coast during the B. P. oil spill (泄露) cleanup, Cave decided to create her own dispersant. Cave raised $ 1.2 million from Chevron, an American multinational energy company, to develop her molecule in 2016.

    "It aims at certain poisons in the sea water,and breaks them up into water,”she said of herdispersant. “It is one of the few legal oil dispersants, " Cave added.

    Despite this achievement, Cave believes she has not quite yet reached success. She regards success as the amount of influence she has made on the community and the world.The creation of themolecule is an achievement,but she believes seeing her work being put to use will truly be her success.

    While Cave may have made the Forbes 30 Under 30 list early in her career, she is never going to slow down. She will make an effort to increase the growth of Mare, which is devoted to developing molecules to solve major social issues.

"Right now, Mare consists of this one molecule that I hope to expand and live up to the Forbes name," Cave said.

Dear Mr.ing,

    I'm Bob Watson, one of the customers in your grocery store. I'm writing to express my idea about your goods.

    Your Supermart is outstanding in many ways. First I enjoy the selection of produce and fresh bakery items. Second your low prices and excellent customer service keep me coming back to Supermart. I have found, however, that I must make a separate shopping trip to one of your competitors because there are many items your store does not carry. This becomes inconvenient for me, as my time is valuable, and I don't like to make two trips. I have been a long time Supermart shopper and hope to continue for many years. If I could find all the items I need in one place, I would be a more satisfied customer.

    Specifically, I have never been able to purchase nacho cheese soup at your store. I can find other flavors (味道) of soup, but your store does not carry nacho cheese soup, a common ingredient (原料) in many of my recipes. In addition, I can only find large wonton wrappers, while many other stores carry both large and small and offer a more varied selection for their customers. Another example is Regent Brand Chili Seasoning. Though it is not a leading brand, it is still common on the shelves of other grocery stores in this area and is superior in flavor to its competitors.

    I sincerely hope to continue a relationship with your store, and I hope that you will consider the possibility of expanding your goods to be more competitive.

Yours truly,

Bob Watson
