A new report from the Center for Evaluation and Education Policy at Indiana University says eighteen states have full-time virtual schools．There are no buildings．All classes are online．
Florida started the first statewide public virtual school in the United States in 1997．Today，the Florida Virtual School offers more man ninety courses．56,000 students were enrolled as of December．Almost sixty percent were female．The school"s website says each student was enrolled in an average of two classes．
Florida Virtual School has now opened the Florida Virtual Global School．Students in other countries pay for classes．Janet Heiking teaches an English class．She lives in Indianapolis, Indiana．Her students live as far away as Africa and Japan．She says they are taking her Advanced Placement class to prepare for attending an American college．They can earn college credits by passing the AP test．
So how good are virtual schools? Studies have shown mixed results, as a new report from Indiana University notes．For example, students at Florida Virtual School earned higher grades than those taking the same courses the traditional way．And they scored higher on a statewide
test．But virtual school students in Kansas and Colorado had lower test scores or performed at a lower level than traditional learners．Studies also find that virtual schools may not save much in operating costs．
Education experts say the mixed results suggest the need for more research to find the best ways to teach in virtual schools．A1so, they say schools of education need to train more teachers to work in both real and virtual classrooms．

Successful and happy people have an idea of how their life should be and they set lots of goals to help them succeed. By setting goals you are taking control of your life. It’s like having a map to show you where you want to go. Think of it this way. There are two drivers. One has a destination in mind which is laid out for her on a map. She can drive straight there without any wasted time or wrong turns. The other driver has no goal or destination or map. She starts off at the same time from the same place as the first driver, but she drives without an aim around, never getting anywhere, just using up gas and oil. Which driver do you want to be？
Winners in life set goals and follow through on them. Winners decide what they want in life and then get there by making plans and setting goals. Unsuccessful people just let life happen by accident. Goals aren’t difficult to set―and they aren’t difficult to reach. It’s up to you to find out what your goals and ideals（理想）really are.
Research tells us that when we write a goal down, we are more likely to achieve. Written goals can be reviewed regularly，and have more power. Like a contract with yourself, they are harder to neglect（忽视）or forget. Also when you write your goals in a particular way, you are able to make yourself be continuously alert（警觉）to situations that will further your goals.
小题1:The writer gave the example of two drivers to show .
| A．how stupid the first driver was | B．the importance of having a map and right direction |
| C．how stupid the second driver was | D．the importance of setting goals |
| A．the successful people set goals for everything and can get help from others |
| B．the unsuccessful people always set unrealistic plans for themselves |
| C．the successful people set goals in their lives and make plans to carry it out |
| D．the unsuccessful people make plans for everything but can not work hard |
| A．try to be realistic about one’s ability |
| B．let others help him or her to make his or her dream come true |
| C．let others understand him or her first，then work together with them |
| D．have a clear mind of what he or she wants in life |
| A．Goals can make you gain everything you want in life |
| B．Only successful people can be happy |
| C．If you want to succeed，you need a set long-term goals instead of short-term Goals |
| D．When we put our goal down on papers, we are more likely to succeed |
| A．Goals help you succeed | B．How to succeed |
| C．Why we always failed | D．A research on setting goals |
In the seventies, scientists developed a process called recombinant or RDNA. Although it sounds difficult to understand, RDNA simply means taking DNA from one animal or plant and putting it into another. By doing so, scientists can create new beings. In doing so, scientists can better understand DNA, especially what parts of DNA do what. After they understand DNA, scientists can begin to cure diseases. Often, the new being created will itself be the cure. Besides curing diseases, RDNA research can also do other things. For example, scientists in Japan have already created “super-trees”. Trees help humans, because they take CO2, which poisons humans, from the air and turns it into oxygen, which lets humans breathe. “Super-trees” do this too, but do it much faster. As things such as cars and factories have already put much CO2 in the area, “super-trees” are badly needed.
Unfortunately, there is a serious danger in RDNA research. Scientists want to create animals to cure old diseases, but these new animals may also create new diseases. It will be a serious problem if the animals escape from the science laboratory and into nature. As these animals are not natural, they may let loose many new powerful diseases.
As a result, RDNA research will create many solutions, but it will also create many problems.

The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the color of a dark-striped zebrafish（斑马鱼） to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebrafish skin color is determined by pigment cells, which contain melanin (黑色素). The number, size and darkness of melanin per pigment cell determine skin color.
It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation (变异) in the gene for melanin production. This results in less pigmented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太阳光紫外线), which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.
小题1: The passage mainly tells us that ________.
| A．people can not change their skin color without any pain |
| B．the new discovery could lead to research into ways to change skin color safely |
| C．pop king Michael Jackson often changed his skin color as he liked |
| D．scientists have found out that people’s skin color is determined by the gene |
| A．nowadays people who want to change their skin color have to suffer a lot from the damage caused by the chemical treatment |
| B．Europeans and Africans have the same gene |
| C．the new discovery could help to find medical treatments for skin cancer |
| D．there are two kinds of genes |
| A．find the different genes of humans’ |
| B．prove the humans’ skin color is determined by the pigment gene |
| C．find out the reason why the Africans’ skin color is dark |
| D．find out the ways of changing people’s skin color |
| A．they are born light-skinned people |
| B．light-skinned Europeans have mutation in the gene for melanin production |
| C．they have fewer activities outside |
| D．they pay much attention to protecting their skin |
| A．neutral（中立的） | B．negative | C．positive | D．indifferent（冷漠） |
The forum, held recently, was jointly organized by the Education Development Research Center of the Ministry of Education in China and the Postgraduate School of the University of Pennsylvania in the US. It aims to find out similarities and differences that exist between two countries in their educational system.
While some educationists in China keep a doubtful eye to the country’s educational system in recent years. Their American counterparts give a positive answer to the basic education in China, saying that it is still one of the best in the world.
An American educationist told reporters that the basic education in the US was criticized in recent years due to its political tendency. On the contrary, Chinese government’s stress on basic education and qualified teachers has set a good example.
At primary and middle school, pupils in China did better in math and science lessons than the US pupils. However, few grow to be world “masters”. Why? Educationists attributed this to China’s stress on examination rather than students’ interest.
Deputy Director of the postgraduate school of Pennsylvania University said American teachers encouraged students to focus on their strong points. In China, students are driven to study to pass the entrance examination test and they do not pay much attention to their own interest.
At the forum, director of the Education Development Research Center Mr. Zhang said in the future, the research center would make its middle and long-term basic education strategy by taking some references from other countries including the US.
He also revealed that for a long time in the future, China would make a breakthrough in setting the policy for quality education.
小题1:This passage is mainly about _________.
| A．quality education development in the future |
| B．why China’s education cultivates few world masters |
| C．China’s good basic education |
| D．genius education at the primary stage |
| A．famous | B．active | C．qualified | D．experienced |
| A．basic education in the US is associated with the government’s political interest. |
| B．the forum aims to find out the reason why there few world masters in China. |
| C．all the educationists in China cast doubts in the country’s educational system. |
| D．Chinese government’s stress on basic education is spoken highly of. |
| A．The US government spends more money on basic education |
| B．American pupils are cleverer than Chinese pupils |
| C．basic education in China is not as successful as that of the US |
