Zhang Ping, who heads China’s National Development and Reform Commission, the central economic planning agency, said only five or six of China’s 30 provinces are targeting annual economic growth of 8 percent or 9 percent．
The remaining provinces are aiming for growth rates of more than 10 percent this year, with some wanting to double economic output in the coming five years．
“China has a planned energy supply of about 4 billion cubic tons of coal equivalent（等量的）for the next five years, and this is not enough to meet demands for economic growth to double,” he was quoted as saying on the news portal Sina．Com．
Beijing is increasingly concerned with the ambitions of Chinese provinces across the country to chase high growth despite the central government’s urgent request for a more moderate and sustainable（可持续的）pace of expansion．
Years of rapid economic growth has taken a toll on China’s environment, with Beijing trying to remove some of the damage now．It has an annual growth target of 7 percent for the next five years, well down from last year’s 10 percent．
Zhang said Beijing has asked local governments to take into account the supply of “energy, environment, water and land” to set more reasonable growth targets．

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．

| 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 _______.
