[不定项选择题]Scientific publishing has long been a licence to print money. Scientists need journals in which to publish their research, so they will supply the articles without monetary reward. Other scientists perform the specialised work of peer review also for free, because it is a central element in the acquisition of status and the production of scientific knowledge.
With the content of papers secured for free, the publisher needs only find a market for its journal. Until this century, university libraries were not very price sensitive. Scientific publishers routinely report profit margins approaching 40% on their operations, at a time when the rest of the publishing industry is in an existential crisis.
The Dutch giant Elsevier, which claims to publish 25% of the scientific papers produced in the world, made profits of more than ￡900m last year, while UK universities alone spent more than ￡210m in 2016 to enable researchers to access their own publicly funded research; both figures seem to rise unstoppably despite increasingly desperate efforts to change them.
The most drastic, and thoroughly illegal, reaction has been the emergence of Sci-Hub, a kind of global photocopier for scientific papers, set up in 2012, which now claims to offer access to every paywalled article published since 2015. The success of Sci-Hub, which relies on researchers passing on copies they have themselves legally accessed, shows the legal ecosystem has lost legitimacy among its users and must be transformed so that it works for all participants.
In Britain the move towards open access publishing has been driven by funding bodies. In some ways it has been very successful. More than half of all British scientific research is now published under open access terms: either freely available from the moment of publication, or paywalled for a year or more so that the publishers can make a profit before being placed on general release.
Yet the new system has not worked out any cheaper for the universities. Publishers have responded to the demand that they make their product free to readers by charging their writers fees to cover the costs of preparing an article. These range from around ￡500 to ￡5,000. A report last year pointed out that the costs both of subscriptions and of these “article preparation costs” had been steadily rising at a rate above inflation. In some ways the scientific publishing model resembles the economy of the social internet: labour is provided free in exchange for the hope of status, while huge profits are made by a few big firms who run the market places. In both cases, we need a rebalancing of power.
Which of the following characterizes the scientific publishing model?
A.Trial subscription is offered.
B.Labour triumphs over status.
C.Costs are well controlled.
D.The few feed on the many.
[不定项选择题]Beauty has always been regarded as something praise worthy. Almost everyone thinks attractive people are happier and healthier, have better marriages and have more respectable occupations. Personal consultants give them better advice for finding jobs. Even judges are softer on attractive defendants (被告). But in the executive circle, beauty can become a liability.
While attractiveness is a positive factor for a man on his way up the executive ladder, it is harmful to a woman.
Handsome male executives were thought as having more integrity than plainer men; effort and ability were thought to account for their success.
Attractive female executives were considered to have less integrity than unattractive ones; their success was attributed not to ability but to factors such as luck.
All unattractive women executives were thought to have more integrity and to be more capable than the attractive female executives. Interestingly, though, the rise of the unattractive overnight successes was attributed more to personal relationships and less to ability than that of attractive overnight successes.
Why are attractive women not thought to be able? An attractive woman is thought to be more feminine and an attractive man more masculine (有男子气概的) than the less attractive ones. Thus, an attractive woman has an advantage in traditionally female jobs, but an attractive woman in a traditionally masculine position appears to lack the "masculine" qualities required.
This is true even in politics. ′When the only clue is how he or she looks, people treat men and women differently,′ says Anne Bowman, who recently published a study on the effects of attractiveness on political candidates. She asked 125 undergraduate students to rank two groups of photographs, one of men and one of women, in order of attractiveness. The students were told the photographs were of candidates for political offices. They were asked to rank them again, in the order they would vote for them.
The results showed that attractive males utterly defeated unattractive men, but the women who had been ranked most attractive invariably received the fewest votes.
The author writes this passage to ____________.
A.give advice to job-seekers who are attractive
B.discuss the negative aspects of being attractive
C.demand equal rights for women
D.state the importance of appearance

A.teaching will becomes a bit difficult
B.they will not get on well with one another

D.they don' t want to learn anything more
[不定项选择题]People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe. In the late 1800s, the Turks made cigarettes popular.
Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco bums, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person′s breathing muscles. Smokers usually take in small amounts that the body can quickly break down.
Nicotine can make new smokers feel dizzy (头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers′ risk of heart disease and stroke.
Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases.
What is the main purpose of the first paragraph?
A.To tell us the bad effects caused by smoking cigarettes.
B.To introduce the history of smoking.
C.To let us know what the cigarettes are made from.
D.To tell the readers that Columbus found the Indians smoking.
