32、n multiple-choice questions. For each question, there are four suggested answers marked A, B, C and D. Choose the one that you think is the best answer. 51 Nick Black obtained a masters degree in computer science from the Georgia Institute of Technology in 2010 and quickly received six-figure offers
33、 for leadership roles at several technology firms. He maintains that his position as a senior compiler engineer is exactly the type of job he expected out of grad school and that the interview process wasnt excessively complicated. Landing a job in todays struggling economy was relatively simple for
34、 Black, in part because he received a masters degree from a top computer science school, but computer science students with either bachelors or masters degrees are in demand now and are expected to be for the next decade. According to a U. S. Bureau of Labor Statistics report, there will be an estim
35、ated 1. 8 million new IT jobs by 2018, a 22 percent jump from todays market. The industry was dealt a blow after the dot-com bubble burst in 2000 following a decade of rampant speculation among investors, but the rise of cloud computing, mobile devices, and applications is fueling more demand in the
36、 sector, academic officials and hiring consultants say. For prospective computer science students, the downside to this employment surge is the resulting increase in applicants, which will likely create tougher admission standards at programs nationwide. Trinity University officials are bracing for
37、a potential influx of computer science students, and have already added an extra session of the introductory class. To navigate the increasingly competitive computer science admissions process, its integral that students focus on honing their mathematical intelligence by taking advanced classes such
38、 as AP Calculus, says Daniel Gallagher, dean of admissions at the Stevens Institute of Technology. Robert Beck, chairman of Villanova Universitys department of computing sciences, notes that taking part in tech-centric extracurriculars could help your chances as well. Once students get past the admi
39、ssion exams, their career prospects are typically bright. At Michigan Technological University, for instance, where more than 300 students major in computer science or software engineering, 93 percent of 2010 undergraduate computer science students had jobs by graduation. Not only are students findi
40、ng jobs at above-average rates, theyre among the best paid out of college, according to a recent survey by the National Association of Colleges and Employers. Computer science majors in the class of 2011 received an average starting salary of $63,017, second only to chemical engineers who make $66,8
41、86, on average. At some top schools like Illinois, average starting salaries are even higher. There, the most recent class of 175 computer science graduates attained an average starting salary of $ 72,597. 52 It can be inferred from the passage that the IT industry_. （ A） needs a large number of pro

A t
45、eam of researchers led by Yukiyasu Kamitani used functional neuroimaging to scan the brains of three people as they slept, simultaneously recording their brain waves using electroencephalography(EEG). The researchers woke the participants whenever they detected the pattern of brain waves associated
46、with sleep onset, asked them what they had just dreamed about, and then asked them to go back to sleep. This was done in three-hour blocks, and repeated between seven and ten times, on different days, for each participant. During each block, participants were woken up ten times per hour. Each volunt
47、eer reported having visual dreams six or seven times every hour, giving the researchers a total of around 200 dream reports. Most of the dreams reflected everyday experiences, but some contained unusual content, such as talking to a famous actor. The researchers extracted key words from the particip
48、ants verbal reports, and picked 20 categoriessuch as “car“, “male“, “female“ and “computer“that appeared most frequently in their dream reports. Kamitani and his colleagues then selected photos representing each category, scanned the participants brains again while they viewed the images, and compared brain activity patterns with those recorded just before the participants were woken up. The researchers analyzed activity in brain areas V1, V2 and V3, which are involved in the earliest stages of visual processing and encode b
