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.

A new survey finds that more than eighty percent of Internet users in the United States search for health information online．The survey found that searching online is one of the leading ways that people look for a second opinion though doctors are still the main source of health information．
Forty-four percent of people are actually looking for doctors or other providers when they search for health information online．Another finding of the survey: Two-thirds of Internet users look online for information about a specific disease or medical condition．
The Internet has also become an important source of e
motional support for people with health problems．Susannah Fox says one in five Internet users has gone online to find other people who have the same condition．It was more popular among people with more serious health issues—one in four people living with chronic diseases （慢性病）．And it was basically off the charts with pe
ople living with rare disease．They are so eager to find other people online who share their health concerns．
A disease is considered rare if it affects fewer than two hundred thousand people worldwide．The rise of social networking has made it easier for people with rare diseases to connect with each other and feel less alone．Social networking is also changing the way some doctors and patients communicate with each other．Dr．Jeff Livingston operates a medical center for women in Irving, Texas．His office uses password-protected software to share information with patients．
“We provide the patient full access to their medical care．Anything I can see, the patient can see．All of their notes, all of their doctor visits are right there．All 
of their lab work is right there．” Dr．Livingston says the software has increased efficiency, reduced costs and improved relations with patients．From the first paragraph, we can know _________．

A shopkeeper sent his son to learn about the secret of happiness from the wisest man in the world. The boy walked a long way, and finally came upon the beautiful castle where the wise man lived.
On entering the main room of the castle, the boy was quite surprised: tradesmen coming and going, people chatting in the corners, and a small orchestra playing soft music. The wise man talked with everyone, and the boy had to wait for two hours before it was his turn.
The wise man listened carefully to the boy’s explanation of why he had come, but told him that he didn’t have time just then to explain the secret of happiness. He suggested that the boy look around the palace and return in two hours.
“Meanwhile, I want to ask you to do something,” said the wise man, handing the boy a teaspoon that held two drops of oil. “As you wander around, carry this spoon with you without allowing the oil to spill.”
The boy began to walk up and down stairs of the palace, keeping his eyes fixed on the spoon. After two hours, he returned to the wise man.
“Well,” asked the wise man, “Did you see the Persian tapestries（挂毯）in the hall? Did you see the garden that took the master gardener ten years to create?” The boy was embarrassed, and replied that he had observed nothing. His only concern had been not to spill the oil.
“Then go back and observe the wonders
of my world,” said the wise man. The boy picked up the spoon and returned to his exploration of the palace. This time he observed all of the works of art on the ceilings and the walls. When he returned, he described in detail everything he had seen.
“But where are the drops of oil?” asked the wise man. Looking down at the spoon he held, the boy saw that the oil was gone.
“Well, there is only one piece of advice I can give you,” said the wise man. “The secret of happiness is to see all the wonders of the world, and never to forget the drops of oil on the spoon.”When the boy arrived at the castle, he .
| A．received a warm welcome from the wise man |
| B．had already missed his chance to talk to the wise man |
| C．didn’t expect to see so many people around |
| D．was shown around the palace by the local people |

The Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the America from being discovered by the people of Europe.
The Atlantic Ocean is only half as big as the pacific, but it is still very large. It is more than 4,000 miles (6,000 km) wide where Columbus crossed it. Even at its narrowest it is about 2,000 miles (3,200 km) wide.
There is so much water in the Atlantic that it is hard to imagine how much there is. But suppose no more rain fell into and no more water was brought to it by rivers. It would take the ocean about 4,000 years to dry up. On the average the water is a little more than 2 miles (3.2 km) deep, but in some places it is much deeper. The deepest spot is near Puerto Rico. This "deep" measures 30,246 feet --- almost six miles (9.6 km).
Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there is little wind. Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the Far North across the paths of ships. We now have such fast ways of travelling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!From the third paragraph, we can learn that ______ .
| A．the Atlantic will dry up in 4,000 years' time |
| B．no river flows into the Atlantic ocean |
| C．it's hard to imagine how much water there is in the Atlantic ocean |
| D．the Ocean floor is rather flat |
Suppose it's February 27th, 2000. You take a steamship to cross the Atlantic to North America, when will you probably get there?
| A．On March 2nd | B．On March 3rd |
| C．On February 28th | D．In eight hours' time |
What can you learn from the last paragraph of the passage ?
| A．The Atlantic has grown smaller than it used to be. |
| B．The Atlantic had grown wider than it used to be. |
| C．Fast ways of travelling make the ocean grow smaller. |
| D．Fast ways of travelling make the ocean seem to grow smaller. |
Nodira, 18, lives in the Tashkent region of Uzbekistan. She was born with a rare disease and is now paralyzed(瘫痪) from the waist down. Her life is confined to a wheelchair but her dreams know no such boundaries. Her hopes for the future include attending university, riding in her father’s car and being able to walk like other children.
Nodira, which means ‘unique’ in Uzbek, is one of five children in a poor family. Every morning, after reciting her prayers, Nodira feeds the hens and goats from her wheelchair. The rest of her day is spent knitting for other people and helping her mother with the household chores.
Nodira has never been to school because it is too far from her home and inaccessible for her wheelchair. A local teacher used to come and tutor her at home and, as a result, she was able to finish third grade. After that, her parents moved to another town and the tutor could not visit as much.
Despite the many difficulties in Nodira’s life she is lucky to be living with 
her family. The stigma(羞辱) attached to the children living with disabilities, combined with the lack of wheelchair access in schools and the economic difficulties faced by many Uzbek families, have led many parents to place children with disabilities in special institutions.
These days, Nodira does homework exercises at home and reads as much as she can. Still, it is unlikely that she will be able to finish her primary education, much less attend university. While missing out on an education is a great disappointment to Nodira, her greatest wish, for a true friend, can still come true. “What I want more than anything is a friend who also has a disability,” she says. “Somebody will not feel sorry for me or make fun of me, and will understand what my life is like.”The underlined sentence in the first paragraph probably means “_____”.
| A．her dreams will help her desert her wheel chair |
| B．her dreams are never limited by her disability |
| C．she often dreams of moving freely without a wheel chair |
| D．she never dreams of recovering from her disability |
Nodira does all the following every day EXCEPT _____.
| A．give food to some animals |
| B．to make clothes from woolen or cotton thread |
C．drive cars designed  for the disabled |
| D．help with the housework |
The underlined word “tutor” in the 3rd paragraph can be replaced by “_____”.
| A．educate | B．visit | C．treat | D．comfort |
What Nodira wants most is ______.
| A．to go to university |
| B．to walk on her own feet |
| C．to finish her primary education |
| D．to find a true friend |
