No one knows how much money Dr. Lyle Tullis gave away to students. I was his colleague for nearly a decade and I never stopped being amazed at his generosity. Our college has a program of providing cross-cultural experiences for students. Lots of students take advantage of summer experience oversea. I discovered that no group left for overseas with some of its members receiving financial help from Dr. Tullis.

    It wasn't that he made a lot of money. For one thing, he taught in a church-run school. There, his salary was half of what those people earned in a tax-supported school.

    Other colleagues occasionally complained about the low pay. Not Lyle Tullis. Occasionally some professors would leave our campus for a better-paid position. They told me they did so because, with better pay, they could provide for their families.

    The size of Lyle Tullis' paycheck never seemed to be the most important thing to him. I realized that one day when I was thanking him for helping a student, his eyes shone as he said to me, “I've got so much money that I don't know what to do with it. So, I just give it away.”

    Most people wouldn't have thought that way. Dr. Tullis drove one of the oldest cars on campus. It was even older than almost any of the students' cars. His home, while comfortable, was not fancy at all. But Lyle Tullis lived with the feeling that he had so much money that he needed to give it away.

    He was one of the favorite on campus. Cynics(愤世嫉俗者) might say he bought fame. But they would misunderstand. Lyle wanted to devote his life, all of it, to helping others.

    We have to admit that many cities around the world today are heavily polluted. Careless methods of production and lack of consumer demand for environment friendly products have actually contributed to the pollution problem. One result is that millions of tons of glass, paper, plastic, and metal containers are produced and these are difficult to get rid of.

    However, today, more and more consumers are choosing “green” and demanding that the products they buy should be safe for the environment. Before they take action to buy a product, they ask questions like these “Will this shampoo add damage to the environment?” “Can this metal container be reused or can it only be used once?”

    A recent study showed that two out of five adults now take the environmental safety of a product into account before they buy it. This means that companies must now adjust the way they make and sell their products to make sure that they are “green” that is, friendly to the environment

    Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds of them advocating green. In addition, some supermarket products carry labels (标签) to show that the product is green. Some companies have adopted the manufacturing (生产) of clean and safe products as their main selling point and emphasize it in their advertising.

    The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the public accept the old attitude of “Buy it, use it, throw it away, and forget it.” The public pressure is on, and gradually business is cleaning up its act.

    Anyone can try to lead a group, but not every individual is cut out for leadership. The better leaders possess a few qualities that can mean the difference between the success and failure of the group. These are the qualities the leader of higher rank will look for when choosing a leader for a group, or when evaluating the performance of a leader. They're also the qualities team members want in a group leader, and appreciate when they find them.

    Take Responsibility

    Group leaders might share tasks around a group as necessary, but eventually a group leader needs to be able to accept that responsibility lies on his shoulders. That means that if things go wrong in a group project, he's the one who must accept the consequences and work out what mistakes are made. The group leader won't always have the power to control everything group members do, but he should be ready to admit any mistakes the group has made as a result of his leadership

    Concern for Members

    The group leader has a commitment to the task or project at hand, but perhaps more importantly, he has a real concern for each and every person who is part of his group. This means getting to know the strengths, weaknesses and goals of team members, as well as making time to build the group through collective activities. The group leader should make sure that everyone is included, even if an individual is new to a group.

    Good Listener

    The group leader needs to be able to listen to the suggestions, complaints and ideas of group members. Not only will this allow complaints to be addressed and potentially suitable ideas to be put into practice, but a leader who listens will also encourage group members to share their concerns and thoughts, creating an atmosphere of free speech and productivity.

    As Internet users become more dependent on the Internet to store information, are people remembering less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.

    In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.

    In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder(文件夹). Surprisingly, people later remember the folder location(位置)better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called “transactive memory”.

    According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize large amounts of information so that they are able to find it at a later date. This doesn't mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.

    Good Morning Britain's Susanna Reid is used to grilling guests on the sofa every morning, but she is cooking up a storm in her latest role-showing families how to prepare delicious and nutritious meals on a tight budget.

    In Save Money: Good Food, she visits a different home each week and with the help of chef Matt Tebbutt offers top tips on how to reduce food waste, while preparing recipes for under ￡5 per family a day. And the Good Morning Britain presenter says she's been able to put a lot of what she's learnt into practice in her own home, preparing meals for sons,Sam,14,Finn,13,and Jack, 11.

    “We love Mexican churros, so I buy them on my phone from my local Mexican takeaway restaurant,”she explains.“I pay ￡5 for a portion(一份),but Matt makes them for 26p a portion, because they are flour, water, sugar and oil. Everybody can buy takeaway food, but sometimes we're not aware how cheaply we can make this food ourselves.”

    The eight-part series(系列节目),Save Money: Good Food, follows in the footsteps of ITV's Save Money: Good Health, which gave viewers advice on how to get value from the vast range of health products on the market.

    With food our biggest weekly household expense, Susanna and Matt spend time with a different family each week. In tonight's Easter special they come to the aid of a family in need of some delicious inspiration on a budget. The team transforms the family's long weekend of celebration with less expensive but still tasty recipes.
