The Basics of Math—Made Clear
Basic Math introduces students to the basic concepts of mathematics, as well as the fundamentals of more tricky areas. These 30 fantastic lectures are designed to provide students with an understanding of arithmetic and to prepare them for Algebra(代数) and beyond.
The lessons in Basic Math cover every basic aspect of arithmetic. They also look into exponents(指数), the order of operations, and square roots. In addition to learning how to perform various mathematical operations, students discover why these operations work, how a particular mathematical topic relates to other branches of mathematics, and how these operations can be used practically.
Basic Math starts from the relatively easier concepts and gradually moves on to the more troublesome ones, so as to allow for steady and sure understanding of the material by students. The lectures offer students the chance to “make sense” of mathematical knowledge that may have seemed so frightening. They also help students prepare for college mathematics and overcome their anxiety about this amazing—and completely understandable—field of study.
By the conclusion of the course, students will have improved their understanding of basic math. They will be able to clear away the mystery(神秘性) of mathematics and face their studies with more confidence than they ever imagined. In addition, they will strengthen their ability to accept new and exciting mathematical challenges.
Professor H. Siegel, honored by Kentucky Educational Television as “the best math teacher in America,” is a devoted teacher and has a gift for explaining mathematical concepts in ways that make them seem clear and obvious. From the basic concrete ideas to the more abstract problems, he is master in making math lectures learner-friendlier and less scary.
With a PhD in Mathematics Education from Georgia State University, Dr. Siegel teaches mathematics at Central Arizona College. His courses include various make-up classes and a number of lectures for future primary school teachers.

Every year, I tell my sons what I'd like for Mother's Day: a letter, something written from the heart and offered freely rather than bought from a store and wrapped neatly. I don't always get my wish, nor do I always take the time to write to my own mother.
This year, my boys will be in two different states on Mother's Day. My mom and dad will be away together, and I'll be driving home from a writer's workshop in Massachusetts. Thinking of the fact that many friends have already lost their mothers and that a few have lost children, I am deeply grateful that what separates us, for now at least, is merely distance. It won't always be so, and there is no way to prepare for that fact other than to appreciate the moment that is. My sons know that they can please me on Sunday with a phone call or an e-mail, and that is enough as I love their words. The very best gift they can possibly give me is their own happiness, the very fact of their busy, full and well-lived lives.
Still, knowing that my years of staying with my sons are over, I do feel doleful. The truth is, I miss being the center of the universe to two little boys. And this holiday can be a bit painful.
I wonder if my own mother ever felt nostalgic (怀旧的，乡愁的) for the passing of my childhood. I wonder if she realizes that she is still at the center of my universe and always has been. I don't often pause to think about it, but of course she is the one who has been right there, at my side from the moment I drew my very first breath. How to ever fully appreciate the woman whose presence and love and example have shaped me into the adult I am?

I decided to cut my front lawn (草坪) today, especially since I live on a main street downtown with lots of traffic. I finished mine and decided to cut my neighbor — Joan’ grass while I was good at it. She is a sweet person who has gone through some trying times in the last year. Her brother passed away because of cancer last year, and her sister (who lives with her) was mentally challenged — yet so sweet!
It was a difficult time with physical and mental challenges that led her employer in our local hospital to let her go after 25 years of service! Lastly, my neighbor Joan, who is a nurse in our local hospital was diagnosed with esophageal(食道) cancer in December. She went through radiation and a long recovery — but thankfully she is in remission(缓解).
Anyway, in short I was leaving my house this afternoon and she stopped me to thank me for cutting her grass. She told me her dad passed away on Friday and she just arrived home from the funeral service, so she didn’t know when she would have time to cut her grass. So, when she arrived home and saw it cut she was more than happy and grateful! I said to her, "You are welcome.It’s just a small act of kindness for a neighbor."
I did it for exercise and pleasure, not knowing it meant more to her than just doing a neighbor a favor!Although a lot of unfortunate matters happened to Joan, she is still .
| A．pessimistic | B．optimistic |
| C．depressed | D．disappointed |

It can be hard to meet people from another culture. From the beginning, people may send the wrong signal（信号）. Or they may pay no attention to signals from another person who is trying to develop a relationship.
Different cultures emphasize （强调）the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in “small talk”, usually over a glass of tea, before they do any job. In many European countries--like the UK or France—people find it easier to build up a lasting working relationship at restaurants or cafes rather than at the office.
Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had expected my speech to be a success and start a lively discussion; instead there was an uncomfortable silence. The people present just stared at me and smiled. After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.
Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values; however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.
People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment（多元文化环境）will offer a wonderful chance for us to learn from each other.In some countries, eating together at restaurants may make it easier for people to ________.
| A．keep each other company | B．share the same Culture |
| C．get to know each other | D．develop closer relations |
The author mentions his experience in Thailand to show that _________.
| A．even talk and silence can be culturally different |
| B．too many words are of no use |

| A．By sharing different ways of life. |
| B．By recognizing different values. |
| C．By accepting different habits. |
| D．By speaking each other’s languages. |
What would be the best title for the text?
| A．Multicultural Environment. |
| B．How to Understand Each Other. |
| C．Cross-Cultural Differences. |

Erica and Steve Lineberry have been rock climbing since 2005. They were first introduced to it while visiting a family in Montana. Now they are at climbing centers, like Inner Peaks in Charlotte, three times a week, and on weekends they climb outdoors.

If you come across the news of the death of Mr. Bean (actor Rowan Atkinson) on your Facebook account and you are curious to know more by opening a link, then think twice. Because the news is fake, a message about his suicide.

Such rumours have their origins in social platforms, where it is not easy to track who made them.
Trishneet Arora, ethical hacker from the city, said: "Culprits are aware that Facebook does not store data on its servers, so the chances of getting tracked are less with such platforms.

So, I immediately removed the post from my wall and also asked my friends on Facebook not to forward the same news."
