People in the United States honor their parents with two special days：Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible (有责任感的) citizens. They give love and care. These two days make us think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child care.

These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery (墓地).On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.

Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays.

Shree Bose is one of the most impressive kids graduating from Fort Worth Country Day High School this year. Bose has a large circle of friends, and there’s one who you may have heard of: President Obama. He has twice publicly recognized her achievements in cancer research and spoken with her in the Oval Office.

If that isn’t enough, Bose recently gave a TED Talk about her work with the cancer drug Cisplatin, which also won her first prize at the Google Science Fair and recognition as one of Glamour magazine’s Young Amazing Women of the Year.

After watching her grandfather struggle with liver cancer, Bose was determined to help out in any way she could. As a high school student though, her

scientific choices were limited. She reached out to various hospitals and research centers, but doctors turned down her requests because they felt she was too inexperienced medically.

Only the North Texas Science Health Center respected her determination and chose to guide her. The results were amazing.

Bose chose to study a protein (蛋白质) and its reaction with the cancer drug Cisplatin. She noticed that when she prevented this protein from growing, Cisplatin was allowed to begin destroying cancer cells once again.

“My project not only contributes to the understanding of the relationship between the protein and Cisplatin, but also suggests a newer, more effective treatment for patients who resist Cisplatin,” Bose said.

Bose’s achievements aren’t limited to the lab, though. She was also captain of her swim team and editor-in-chief of her school paper.

Bose is currently getting practical experience at the National Institute of Health and she’ll be attending Harvard in the fall. She plans to study molecular biology and go to medical school. Eventually, she would like to be a doctor.

Everybody in this world is different from one another. But do you know that understanding differences can help you better manage your money?

As we grow up, we gradually develop a set of our own values or beliefs. These are influenced by society, our family, the education we receive and so on. Once this value system is set up, it’s not easy to change later in life.

Financial experts say that everyone also has their own belief of how to manage their finances. This is part of our value system and it has a great impact on the way we look after our money.

According to our different values, experts put us in three categories. They are: the ant, the cricket and the snail.

The ant—works first

Just like ants who work heart and soul in summer in order to store food for winter, these people don’t care about enjoying the moment. They work very hard and save money they earn so that they can enjoy life when they get old and retire. The ant loves to save but they could make more out of their money if they were willing to invest in some funds and stocks with low risk.

The cricket—fun first

The cricket wants to enjoy everything now and doesn’t think too much about the future. They even borrow money when they really want something. Many young people now belong to this group. These people have little savings. When they get old, they might have problems. They should learn to save and buy insurance.

The snail—lives under pressure

The snail refers to people who make life difficult for themselves. They take big long-term loans from the bank in order to buy things such as luxury houses. They are happy to take big loans even though they are not sure whether they can afford it. This can cause problems in the future. They should plan more carefully.

Tired of all the pushing in supermarkets? Fed up with waiting in endless lines to pay for what you have bought? Angry at wasting time in traffic jams only to find no parking spaces when you eventually arrive at the store? If this is you, then online shopping is the answer to your dreams of trouble-free shopping. Or is it?

Online shopping brings its own challenges. Here are a few things to bear in mind when browsing (浏览) various websites. The claim made by online sites is that shopping online is a safe and secure way to make purchases. The evidence challenges this. In any case, you only have to be the victim of fraud (诈骗) once to experience all the problems that come with this form of stealing. Use only sites that have a trusted history and an excellent reputation.

Another problem is the appearance of items in reality is often quite different from what you see on your computer screen. This might not be a problem if you are buying washing up powder but could be a major disappointment when that beautiful blue dress you ordered turns up in green. Also, product descriptions are sometimes simply untrue. Perhaps the wisest plan is to purchase items where design and color are not essential to customer satisfaction.

Some even argue that online shopping indirectly contributes to global warming. Yes, your car can stay parked but how are online goods delivered? Often by some large vans pouring out carbon monoxide and adding to our already desperate traffic problems. You are also by now becoming increasingly irritated (使烦恼) by the fact that the delivery is late and you have wasted the leave from work you have taken to receive it!

Without question, online shopping is here to stay and it has its benefits. However, perhaps it is not as wonderful as some of its supporters claim it to be.
