Looking at the basic biology systems, the world is not doing very well. Yet economic indicators show the world is prospering. Despite a slow start at the beginning of the eighties, global economic output increased by more than a fifth during the decade. The economy grew, trade increased, and millions of new jobs were created. How can biological indicators show the opposite of economic indicators?
The answer is that the economic indicators have a basic fault: they show no difference between resources uses that sustain progress and those uses that will hurt it. The main measure of economic progress is the gross national product (GNP). In simple terms, this totals the value of all goods and services produced and subtracts loss in value of factories and equipment. Developed a half-century ago, GNP helped establish a common way among countries of measuring change in economic output. For some time, this seemed to work reasonably well, but serious weakness are now appearing. As indicated earlier, GNP includes loss in value of factories and equipment, but it does not take into account the loss of
natural resources, including nonrenewable resources such as oil or renewable resources such as forests.
This basic fault can produce a misleading sense of national economic health. According to GNP, for example, countries that overcut forest actually do better than those that preserve their forest. The trees cut down are counted as income but no subtraction is made for using up the forests.
Passage One （预测阅读话题：互联网时代受争议的热点）
California has a new program called the Digital Textbook Initiative. "Starting this fall with high school math and science, we will be the first state in the nation to provide schools with a state-approved list of digital textbooks." That was Governor in June, talking about his effort to get schools to use materials available free online. He listed reasons why he thinks digital textbooks make sense. California approves traditional textbooks in six-year cycles. Digital ones can offer the latest information. They lighten the load of school bags. They save paper and trees, and make learning more fun and interactive. And above all, he said, they help schools with their finances.
The state has had to make severe cuts in school spending because of deep financial problems. More than six million students attend California public schools. Earlier this year, California invited content developers to offer digital math and science materials for high schools. These had to meet at least 90% of the state's learning requirements. Specially trained teachers examined 16 textbooks and approved ten of them.
Six of the ten were published by the CK 12 Foundation, a non-profit group that had been developing digital science and math books for about two years. The foundation paid teachers and other education professionals to write and edit them. The money came from a group financed by the Khosla Family. California cannot require schools to use the digital textbooks. Individual school districts will have to decide for themselves.
Susan Martimo, a California Department of Education official, says she does not expect widespread use right away. Her best guess is that some schools with a lot of technology will be the first to use them, but only in addition to their traditional books.
School administrators point out that the texts may be free online, but students need a way to access them. Not everyone has a computer or electronic reader. Schools could print out copies, but that would not help the environment. Also, there is the cost to train teachers to use digital textbooks effectively.

5. What can be inferred from the last paragraph?

Passage Two（预测话题：医疗）
A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what's happening in their brains. When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons (神经元) are responsible for this processing.
Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using a technology called functional magnetic resonance imaging (功能性核磁共振成像), or fMRI, scientists can visualize (使显现) which parts of the brain receive more oxygen-rich blood—and therefore, which parts are working to process information.
An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.
The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.
In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.
6. What is responsible for processing a signal sent by people's eyes?
[A] Oxygen-rich blood.
[B] Neurons in the brain.
[C] A small region of the brain.
[D] The central part of the brain.
7. What do we learn from the third paragraph?
[A] Cells in your brain use more oxygen than cells elsewhere.
[B] It is impossible to discover which parts of the brain process information.
[C] The more oxygen a neuron consumes, the more blood it needs.
[D] fMRI helps scientists to discover how the brain develops intelligently.
8. What does the author mean "By highlighting the areas of the brain at work" (Line 3-4, Para. 4)?
[A] Scientists who are working give light to the parts of the brain.
[B] Scientists us fMRI to make the parts of the brain work.
[C] Scientists stop the parts of the brain from processing information.
[D] fMRI marks the parts of the brain that are processing information.
9. What did the researchers experiment on according to the passage?
[A] fMRI machines.
[B] Thousands of pictures.
[C] Animals, objects, and fruits.
[D] Two volunteers.
10. The best title for the passage would be _______.
[A] Your Thoughts Can Be Scanned
[B] A Technological Dream
