Questions are based on the following passage．
For years， high school students have received identical textbooks as their classmates．Even asstudents have different learning styles and abilities， they are force-fed the same materials．"Imagine adigital textbook where because I"m adifferent person and learn differently， my book is different thanyour book，" said Richard Baraniuk， founder of OpenStax．
OpenStax will spend two years developing the personalized books and then test them on Houston-area students．The books will also go through a review and evaluation process similar to traditionaltextbooks．Baranluk expects 60 people to review each book before publication to ensure its quality．The idea is to make learning easier， so students can go on to more successful careers and lives．
Baraniuk isn"t just reproducing physical textbooks on digital devices， a mistake e-book publishers havemade．He"s seriously rethinking that the educational experience should be in a world of digital tools．Todo this means involving individuals with skills traditionally left out of the textbook business．Baraniuk iscurrently hiring cognitive scientists and machine learning experts．Baraniuk wants to use the tactics of Google， Netfllx and Amazon to deliver a personalized experience．These Web services all rely oncomplex algorithms （算法） to automatically adjust their offerings for customers．Just as Netlix recommends different movies based on your preferences and viewing history， a textbook might present materials at a different pace．The textbook——which will be stored on a range of digital devices——will automatically adjust itself thanks to machine learning．As a student learns about a topic， he or she could be interrupted by brief quizzes that evaluate， whether he or she masters the area．Depending on how the student does， the subject could be reinforce~l with more material．Or a teacher could be automatically e-mailed that the student is struggling with a certain concept and could use some one-on-one attention．This personalized learning experience is possible thanks to the wealth of data a digital textbook cantrack．This data can be used to better track students" progress during a course．Parents and teacherscan monitor a student"s development and provide in time more proper assistm ce．With personalizedlearning methods， our students" talents will be better developed．
What do we learn about personalized books？ 查看材料
A.Their quality will be ensured since they are developed by OpenStax．
B.They will be examined and judged before being published．
C.They will overlook different learning styles and abilities．
D.They will be much similar to traditional textbooks．
听力原文：M: Hello, University Books. Tim Weber speaking.
W: Hi, Tim, this is Ruth.
M: Oh, hi, Ruth, What's up？
W: Well, the Student Federation needs a couple of volunteers to give guided tours to the new students next week. Would you be able to help out？
M: That depends on the days you have in mind. I'm working here full-time before classes begin. It's really busy now, with all the textbook orders coming in, but I do have some time off.
W: What about Saturday-？ Most new students arrive on the weekend.
M: Sorry, I have to work all day Saturday. How about Thursday and Friday？ I've got both mornings free.
W: I don't have the schedule on me. Ken's got it. Maybe you ean set something up with him.
M: I'll only be able to spare a couple of hours, though.
W: No problem. I'll ask Ken to get in touch with you later today. Will you be at this number？
M: Yeah, till four... Look, I've got to go. I have to get all the orders out before I leave today.
W: OK, thanks, Tim. Bye.

Ms Byron is one of 419 students (out of 8,744 who applied) who were accepted for Google's "summer of code". While it sounds like a hyper-nerdy summer camp, the students neither went to Google's campus in Mountain View, California, nor to wherever their mentors at the 41 participating open-source projects happened to be located. Instead, Google acted as a matchmaker and sponsor. Each of the participating open-source projects received $500 for every student it took on; and each student received $4,500 ($500 right away, and $4,000 on completion of their work). Oh, and a T-shirt.
All of this is the idea of Chris DiBona, Google's open-source boss, who was brainstorming with Larry Page and Sergey Brin, Google's founders, last year. They realised that a lot of programming talent goes to waste every summer because students take summer jobs flipping burgers to make money, and let their coding skills degrade. "We want to make it better for students in the summer", says Mr. DiBona, adding that it also helps the open- source community and thus, indirectly, Google, which uses lots of open-source software behind the scenes. Plus, says Mr. DiBona, "it does become an opportunity for recruiting".
Elliot Cohen, a student at Berkeley, spent his summer writing a "Bayesian network toolbox" for Python, an open-source programming language. "I'm a pretty big fan of Google", he says. He has an interview scheduled with Microsoft, but "Google is the only big company that I would work at", he says. And if that doesn't work out, he now knows people in the open-source community, "and it's a lot less intimidating".
Ms Byron's comment on her own summer experiment is ______.
A．negative
B．biased
C．puzzling
D．enthusiastic

Lighting Africa is a ＄12 million project which intends to bring light to the poorest regions across sub-Saharan Africa. The program works with the lighting industry to develop clean, affordable lighting and energy solutions for millions without access to electric grids. Its aim is to accelerate the market and to develop education programs that inform. off-grid populations currently dependent on costly, inefficient and hazardous fuel-based lighting about modern alternatives.
Cecile used to spend ＄3-4 a month on kerosene for her lamp. That is a large proportion of her earnings—like 70 percent of the population she lives on less than ＄2 a day. In the weeks since buying her lantern she has managed to read four books including Madame Bovary. by Gustave Flaubert and Emile Zola's Germinal. She is among the most learned in a society which has the world's lowest literacy rate, according to a 2007 UN Human Development Report. When she graduates next year she will teach in a local junior school She makes ends meet by holiday jobs as a cleaner and an IT trainer. To earn her daily ration of cornmeal she does shifts from May to September in a corn field.
The lanterns are designed to look like the kerosene ones they are replacing in order to increase adoption among the population. Each has a small solar panel on the top and costs an average ＄30, although some cost ＄100, depending on the size of the battery and the number of LED lights it contains.
Because of the large number of sunlight hours in Burkina Faso, the lamps can be relied on to work whenever needed. The battery life is 2-4 years, and can be replaced once they lose their storage capacity. The LED lights last 5-10 years.
Although it is barely out of its trial period the project, Chabanne said there are signs the project is a boon for the population in areas other than household savings and education. "There are fewer people reporting eye problems to the local hospital."
