Passage One?（預(yù)測(cè)閱讀話題：互聯(lián)網(wǎng)時(shí)代受爭(zhēng)議的熱點(diǎn)）

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.

1. We learn from the passage that the Digital Textbook Initiative _______.
[A] will probably take effect in six years
[B] covers all the high school subjects
[C] has been approved by all states
[D] is advocated by California state governor

2. The main reason for promoting digital textbooks is to _______.
[A] help schools save money
[B] benefit the environment
[C] provide interesting materials
[D] reduce students' heavy burden

3. What does the author say about CK 12 Foundation?
[A] It approved and produced 16 digital textbooks.
[B] It paid teachers to write digital textbooks.
[C] It is financed by California state government.
[D] It makes money through developing digital textbooks.

4. According to Susan Martimo, digital textbooks _______.
[A] are not likely to have a widespread use
[B] will soon replace traditional ones
[C] will first be adopted by well-equipped schools
[D] are certain to be approved by school districts

5. What can be inferred from the last paragraph?
[A] Schools are reluctant to print out copies.
[B] The use of digital textbooks is not really free.
[C] Students need to pay for computers.
[D] Training teachers to use the textbooks is not efficient.

1.
答案：D
解析：
本題為推斷題。根據(jù)題干關(guān)鍵詞Digital Textbook Initiative定位到文章第一段。最后兩句提到州長(zhǎng)為了讓學(xué)校使用免費(fèi)網(wǎng)上資料而作出努力，并列出了他認(rèn)為電子課本有意義的原因。由此可知，電子課本計(jì)劃受到州長(zhǎng)的支持，故答案應(yīng)選D。

2.
答案：A
解析：
本題為細(xì)節(jié)題。根據(jù)題干關(guān)鍵詞reason，promoting digital textbooks定位到第一段末句和第二段。第二段末尾的above all，道明了最主要的原因，即它們對(duì)學(xué)習(xí)財(cái)政有幫助。由此可知，答案應(yīng)選A。

3.
答案：B
解析：
本題為細(xì)節(jié)題。根據(jù)題干關(guān)鍵詞CK 12 Foundation定位到第五段。根據(jù)倒數(shù)第二句話The foundation paid teachers and other education professionals to write and edit them.可知答案應(yīng)選B。

4.
答案：C
解析：
本題為細(xì)節(jié)題。根據(jù)題干關(guān)鍵詞Susan Martimo定位到倒數(shù)第二段。根據(jù)最后一句話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.可知答案應(yīng)選C。

5.
答案：B
解析：
本題為推斷題。根據(jù)題干信息定位到最后一段。最后一段提到，網(wǎng)上的書(shū)可能是免費(fèi)的，但并不是每個(gè)學(xué)生都有電腦或電子閱讀器。而培訓(xùn)教師有效地使用電子課本也得花錢(qián)。由此可知電子課本的使用并不是真正的免費(fèi)。答案選B。

Passage Two（預(yù)測(cè)話題：醫(yī)療）

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 (神經(jīng)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 (使顯現(xiàn)) 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
[C] The Recent Development in Science and Technology
[D] A Device that Can Help You Calculate

6.
答案：B
解析：
本題為細(xì)節(jié)題。根據(jù)題干關(guān)鍵詞responsible for processing定位到文章第二段末句Cells in your brain called neurons (神經(jīng)元) are responsible for this processing.由此可知答案選B。

7.
答案：C
解析：
本題為推斷題。根據(jù)題干信息定位到第三段。第二句提到神經(jīng)元越活躍，消耗的氧氣越多。由此可知，答案應(yīng)選C。

8.
答案：D
解析：
本題為語(yǔ)義題。根據(jù)題干信息定位到第四段末句。該句指的是人在看不同影像是，通過(guò)突顯出正在工作的大腦區(qū)域，fMRI可以幫助科學(xué)家確定與不同影像有關(guān)的特點(diǎn)大腦活動(dòng)形態(tài)。由此可知答案選D。

9.
答案：D
解析：
本題為細(xì)節(jié)題。根據(jù)題干關(guān)鍵詞experiment定位到倒數(shù)第二段。首句提到研究人員通過(guò)讓兩名志愿者觀看多幅照片來(lái)測(cè)試大腦活動(dòng)。由此可知，答案選D。

10.
答案：A
解析：
本題為主旨題。文章首段介紹加利福尼亞的研究人員找到一種方法，能通過(guò)掃描大腦的活動(dòng)知道人們?cè)诳词裁礀|西。接下來(lái)的幾段是介紹這一方法的原理和試驗(yàn)過(guò)程。由此可知答案選A“你的思維可以被掃描”最合適。?
