One U.S. state senator proposed that high school students be allowed to study either foreign language or computer coding.[A] As computer coding has become an increasingly sought-after skill, more K-12 schools are working it into their curriculums. Some states have considered allowing students to forgo (放弃) foreign language for coding classes, despite opposition from educators.[B] There’s a debate over whether it’s appropriate to teach coding in elementary schools, with fierce opinions on each side. When it comes to allowing coding to fill foreign language requirements, though, most educators agree: Coding should be added to curriculums, but not at the expense of foreign language classes.[C] The idea is that computer programming is a language, allowing people to communicate with machines and programs. It’s the language of the 21st century and more valuable than a natural language, some advocates argue. The computer science field is growing faster than schools can keep up because of budget constraints and a lack of skills training for teachers.[D] According to the 2016 U.S. News/Raytheon STEM Index, computer science jobs have helped boost wages in the U.S., and computer-related jobs hold the top seven positions in STEM fields for highest number of workers. Foreign language interest, on the other hand, is declining for the first time since 1995. The number of higher education language enrollments declined between 2009 and 2013 by more than 111,000 spots, according to the Modern Language Association of America.[E] “I think the opportunity to give people a choice is important,” says Florida state Senator Jeremy Ring, who introduced a bill last year that would allow Florida students to choose between foreign language and coding classes for the purpose of university admissions requirements. “I think if you’re going to give two years of language in high school, you might as well do computer coding.”请选择和题干内容相一致的段落。A、[A]B、[B]C、[C]D、[D]E、[E]

Female applicants to postdoctoral positions in geosciences were nearly half as likely to receive excellent letters of recommendation, compared with their male counterparts. Christopher Intagliata reports.As in many other fields, gender bias is widespread in the sciences. Men score higher starting salaries, have more mentoring （指导）, and have better odds of being hired. Studies show they're also perceived as more competent than women in STEM （Science, Technology, Engineering, and Mathematics） fields. And new research reveals that men are more likely to receive excellent letters of recommendation, too."Say, you know, this is the best student I've ever had," says Kuheli Dutt, a social scientist and diversity officer at Columbia University's Lamont campus. "Compare those excellent letters with a merely good letter: 'The candidate was productive, or intelligent, or a solid scientist or something that's clearly solid praise,' but nothing that singles out the candidate as exceptional or one of a kind."Dutt and her colleagues studied more than 1,200 letters of recommendation for postdoctoral positions in geoscience. They were all edited for gender and other identifying information, so Dutt and her team could assign them a score without knowing the gender of the student. They found that female applicants were only half as likely to get outstanding letters, compared with their male counterparts. That includes letters of recommendation from all over the world, and written by, yes, men and women. The findings are in the journal Nature Geoscience.Dutt says they were not able to evaluate the actual scientific qualifications of the applicants using the data in the files. But she says the results still suggest women in geoscience are at a potential disadvantage from the very beginning of their careers starting with those less than outstanding letters of recommendation."We're not trying to assign blame or criticize anyone or call anyone conscious sexist. Rather, the point is to use the results of this study to open up meaningful dialogues on implicit gender bias, be it at a departmental level or an institutional level or even a discipline level." Which may lead to some recommendations for the letter writers themselves.What do we learn about applicants to postdoctoral positions in geosciences?A.There are many more men applying than women.B.Chances for women to get the positions are scare.C.More males than females are likely to get outstanding letters of recommendation.D.Male applicants have more interest in these positions than their female counterparts.What do studies about men and women in scientific research show?A.Women engaged in postdoctoral work are quickly catching up.B.Fewer women are applying for postdoctoral positions due to gender bias.C.Men are believed to be better able to excel in STEM disciplines.D.Women who are keenly interested in STEM fields are often exceptional.What do the studies find about the recommendation letters for women applicants?A.They are hardly ever supported by concrete examples.B.They contain nothing that distinguishes the applicants.C.They provide objective information without exaggeration.D.They are often filled with praise for exceptional applicants.What did Dutt and her colleagues do with the more than 1,200 letters of recommendation?A.They asked unbiased scholars to evaluate them.B.They invited women professionals to edit them.C.They assigned them randomly to reviewers.D.They deleted all information about gender.What does Dutt aim to do with her study?A.Raise recommendation writers' awareness of gender bias in their letters.B.Open up fresh avenues for women post—doctors to join in research work.C.Alert women researchers to all types of gender bias in the STEM disciplines.D.Start a public discussion on how to raise women's status in academic circles.

On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the "wisdom of crowds" effect. The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate. This effect capitalizes on the fact that when people make errors, those errors aren't always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won't cancel each other out. In more technical terms, the wisdom of crowds requires that people's estimates be independent. If, for whatever reasons, people's errors become correlated or dependent, the accuracy of the estimate will go down. But a new study led by Joaquin Navajas offered an interesting twist(转折)on this classic phenomenon. The key finding of the study was that when crowds were further divided into smaller groups that were allowed to have a discussion, the averages from these groups were more accurate than those from an equal number of independent individuals. For instance, the average obtained from the estimates of four discussion groups of five was significantly more accurate than the average obtained from 20 independent individuals. In a follow-up study with 100 university students, the researchers tried to get a better sense of what the group members actually did in their discussion. Did they tend to go with those most confident about their estimates? Did they follow those least willing to change their minds? This happened some of the time, but it wasn't the dominant response. Most frequently, the groups reported that they "shared arguments and reasoned together." Somehow, these arguments and reasoning resulted in a global reduction in error. Although the studies led by Navajas have limitations and many questions remain, the potential implications for group discussion and decision-making are enormous. What is paragraph 2 of the text mainly about? A. The methods of estimation.B. The underlying logic of the effect.C. The causes of people's errors.D. The design of Galton's experiment.
