I think people are the biggest source of knowledge for anybody.Right from childhood，we have learned things by watching others.Whatever field you want to gain knowledge in，there must be many who have experience in that field.So make use of this valuable source of information by learning from the experience，success，mistakes and skills of others. Study carefully and associate with people who are experts in the field you want to gain knowledge in.
The next best source of knowledge should be books.There are millions and millions of books in every language and on almost any topic imaginable.Whatever problem you are facing must have been faced by somebody else before，and its solution is likely to have been preserved in the form of a book.If you are serious about gaining knowledge about a topic，then read any book，magazine，article etc.You can lay your hands on the books related to that topic.Read as much as you can.
It is said that experience is a great teacher，so learn from your past experience and the experience of others.Learn from your and others’ past and present achievements as well as mistakes.
Experimenting with new things and observing new things can help you learn very quickly. Keep in mind，though，that while experimenting，you may encounter a few failures , too.Do not become discouraged as failures are a part of the learning curve，especially while attempting something new.Try to earn from failures instead of becoming disheartened.

The idea of the genome as a book is not, strictly speaking, even a metaphor．It is true to a great extent．A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their groupings．So is a genome．The only difference is that all English books read from left to right, while some parts of the genome read from left to right while some from right to left, but never both at the same time．
While English books are written in words of different lengthens using twenty-six letters, genomes are written entirely in words of three-letter length, using only four letters, and instead of being written on flat pages, they are written on long chains of DNA molecules （分子）．
The genome is a very clever book, because in the right condition it can both photocopy itself and read itself．
小题1:How do human genomes read according to the passage?___________
| A．Only from left to right． |
| B．Only from right to left． |
| C．From both directions at the same time． |
| D．From one direction at a time． |
| A．is as long as the River Danube |
| B．can be easily placed on the head of a pin |
| C．is coded with an alphabet of four letters |
| D．is smart enough to read and take photos of itself |
| A．specialists in the field |
| B．general readers |
| C．natural scientists |
| D．readers with professional knowledge |
| A．to focus on the differences between the two |
| B．to lay emphasis on the similarities between the two |
| C．to simplify the concept of the human genome |
| D．to give an exact description of the human genome |
Life would be bitter for most Americans. They spend about $13 billion a year buying all sorts of chocolate treats.
However, for the African children who toil under slavelike conditions on cacao plantations, life is not sweet. The cacao bean is the main ingredient in the chocolate. According to a 2002 survey by the International Institute of Tropical Agriculture and the US Agency for International Development, about 284,000 children work in dangerous conditions on cacao farms in western Africa.
More than half those children are younger than 14. Many were sold into forced labor to work 12 hours or more a day on the cacao plantations.
A number of international organizations, including several African governments, recently began a program to eliminate(消除) child labor on cacao plantations. Under the program, government officials will remove children from abusive working situations while teaching farmers about child labor issues.
The program will also make borrowing money easier for cacao farmers. Officials hope farmers will use the money to invest in their farms and hire paid laborers.
小题1:The cacao bean is the main ingredient in _______.
| A．treats |
| B．coffee |
| C．chocolate |
| D．cigarettes |
| A．About 284,000. |
| B．About 142,000. |
| C．About 467,000. |
| D．About 876,000. |
| A．cacao farms in western Africa rely heavily on child labor |
| B．children in Africa know how to make the best chocolate |
| C．candy bars sold in the United States are made on plantations in Africa |
| D．eating too much chocolate is bad for your health |
Think about some of the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating.
Many children’s games have a practical side. Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones, which sharpens the hand-eye coordination (协调) needed in hunting.
Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.
Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it — some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to spread hope through soccer. He created a foundation to provide poor children with not only soccer balls but also a promising future.
Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life.
小题1:Through playing hide-and-seek, children are expected to learn to ________.
| A．be a team leader |

Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution(重新分配)are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.
This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers" overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.
Saudi Arabia"s attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.
小题1:What is most likely to be discussed in the paragraph that follows?
| A．Ways to reduce the costs of building dams. |
| B．Steps to improving water use management. |
| C．Measures to deal with worldwide water shortages. |
| D．Approaches to handling the pressure on water supply. |
| A．much of the world"s water is available for use |
| B．people in high rainfall countries feel lucky |
| C．the costs of water redistribution should be considered |
| D．water can be easily carried through pipes across the world |
| A．water supply and increasing population |
| B．water shortages and environmental protection |
| C．water redistribution and wildlife protection |
| D．water use management and agriculture |
The tree contains a chemical called salicin（柳醇）. From salicin, researchers in the 1800s discovered how to make salicylic acid（酸）. And in 1897, a chemist named Felix Hoffmann at Friedrich Bayer and Company in Germany created acetyl salicylic acid. Later it became the active substance in a new medicine that Bayer called aspirin. The "a" came from acetyl. The "spir" came from the spirea plant, which also produces salicin. And the "in" Well, that is a common way to end medicine names.
In 1982, a British scientist shared the Nobel Prize in Medicine in part for discovering how aspirin works. Sir John Vane found that aspirin blocks the body from making natural substances called prostaglandins（前列腺素）.Prostaglandins have several effects on the body. Some cause pain and the expansion, or swelling（ 肿瘤; 膨胀）, of damaged tissue. Others protect the lining of the stomach and small intestine. Prostaglandins also make the heart, kidneys and blood vessels （血管）work well. But there is a problem. Aspirin works against all prostaglandins, good and bad. Scientists learned how aspirin interferes with an enzyme（酶）. One form of this enzyme makes the prostaglandin that causes pain and swelling. Another form of the enzyme creates a protective effect. So aspirin can reduce pain and swelling in damaged tissues. But it can also harm the inside of the stomach and small intestine（肠）.
小题1:What sickness can the medicine from the willow deal with according to the passage?
| A．Cold | B．Toothache | C．Cancer | D．Skin disease |
| A．It results from pain. |
| B．It prevents the lining of the stomach and small intestine. |
| C．It causes blood vessels to work wrongly. |
| D．It is sometimes good but sometimes bad. |
| A．Aspirin can treat almost diseases. |
| B．Aspirin can create the protective enzyme. |
| C．Aspirin can harm the inside of the stomach and small intestine. |
| D．Aspirin can protect the inside of the stomach and small intestine. |
