2011年5月，小毛于烹饪学校毕业后，到森林大酒店做厨师。森林大酒店于6月和小毛签订了为期5年的劳动合同。合同中约定试用期为半年，试用期满进行考试，若考试不合格则延长试用期半年。森林大酒店每月支付小毛工资3000元。小毛在试用期内工作认真，但由于缺少经验，半年后考试不合格，森林大酒店决定延长其试用期半年，并通知小毛，延长试用期期间，小毛的工资为原工资的50%，即1500元。小毛认为这一决定没有道理，就找到森林大酒店评理。森林大酒店经理称：在延长试用期期间降低工资是森林大酒店多年的做法，对小毛不能搞特殊。请回答下列1-2题。

森林大酒店在延长试用期期间降低小毛工资的做法是否正确？

A:森林大酒店在延长试用期期间降低小毛工资是正确的，因为这是该森林大酒店多年的做法，小毛不能搞特殊 B:森林大酒店在延长试用期期间降低小毛工资是正确的，因为小毛试用期满考试不合格 C:森林大酒店在延长试用期期间降低小毛工资是不正确的，因为这种做法违反了劳动合同法 D:上述说法都不正确

With the Internet fast becoming the most important communications channel, it is untenable for the United States not to have a regulator to ensure nondiscriminatory access, guarantee interconnectivity among rival networks and protect consumers from potential abuse.
Yet that’s exactly where the United States Court of Appeals for the District of Columbia Circuit left us all when it said this month that the Federal Communications Commission didn’t have the authority to regulate the Internet—and specifically, could not force the cable giant Comcast to stop blocking peer-to-peer sites.
The decision, in the words of the F. C. C.’s general counsel, Austin Schlick, undermines the agency’s ability to serve as "the cop on the beat for 21st-century communications networks." It also puts at risk big chunks of the F. C. C.’s strategy for increasing the reach of broadband Internet to all corners of the country and fostering more competition among providers.
Chairman Julius Genachowski said the commission is not planning to appeal the decision, and is studying its options. The F. C. C. could try to forge ahead with its broadband plan despite the court’s decision. Or Congress could give the F. C.C. specific authority to regulate broadband access. But the court tightly circumscribed the F. C. C.’s actions. And with Republicans determined to oppose pretty much anything the administration wants, the odds of a rational debate on the issues are slim.
Fortunately, the commission has the tools to fix this problem. It can reverse the Bush administration’s predictably antiregulatory decision to define broadband Internet access as an information service, like Google or Amazon, over which it has little regulatory power. Instead, it can define broadband as a communications service, like a phone company, over which the commission has indisputable authority.
The F. C. C. at the time argued that a light regulatory touch would foster alternative technologies and aggressive competition among providers. It assumed that the Internet of the future would be dominated by companies like AOL that bundle access with other services, justifying its conflation of access and information. And it claimed that it could still regulate broadband access even if it was classified as a service. All it had to do was convince the courts that it was necessary to further other statutory goals, like promoting the roll-out of competitive Internet services. This legal argument did not hold up.
Any move now by the F. C. C. to redefine broadband would surely unleash a torrent of lawsuits by broadband providers, but the commission has solid legal grounds to do that. To begin with, the three arguments advanced by the F. C.C. during the Bush years have proved wrong. Rather than seeing an explosion of new competition, the broadband access business has consolidated to the point that many areas of the country have only one provider. Broadband Internet has unbundled into a business with many unrelated information service providers vying for space on the pipelines of a few providers. And most persuasively: broadband access is probably the most important communications service of our time. One that needs a robust regulator.
The F. C.C. intends to

A:restrict access to broadband Internet. B:facilitate access to broadband Internet. C:block peer-to-peer sites. D:monopolize access to broadband Internet.

Millions of copies of console and computer- based" brain trainers" are sold worldwide every year, claiming to make peoples’brains younger, better, faster or bigger. The theory seems to make sense: regularly exercising the brain with tests and puzzles can improve brain skills and help people become better at everyday thinking tasks.
But recent research suggests scientific evidence is lacking.
The BBC’s Brain Test Britain experiment wants to find out if brain training really works, and is aiming to get thousands of members of the public to train for 10 minutes a day ,three times a week ,for at least six weeks.
Scientific experiments and their findings should be evaluated by independent experts in a process called "peer review". This is the minimum standard by which the quality of any research is judged.
Very little research on commercial brain trainers has been peer reviewed.
Instead, manufacturers often quote unsupported testimonials from" satisfied users". None of these are acceptable substitutes for peer review.
A proper" control group" is the backbone of any valid scientific study.
With a brain training study, the control group of participants should do the same amount of a mental activity as the brain - training group, but using a" non - brain training" activity such as a crossword.
Scientists should then be able to compare the results from the two groups to see how genuinely effective the brain training tasks were.
Studies that have been used to support the claims made by commercial brain trainers often have no control group at all, or a control group that is not as mentally active as the trained group.
In order to see how much you have improved, you need to know where you were at the start. To do this. scientists use a" benchmarking test"—the same test, taken at the beginning and end of an experiment.
Benchmarking tests should he different from the brain training tasks. This way, scientists can see if the effects of brain training are transferable to other mental tasks.
Studies used to support the claims made by commercial brain trainers often use tests for benchmarking that are identical—or very similar—-to the tests used during training
Which statement about" peer review" is right

A:The testimonials from" satisfied users" of a product can be classified as peer review. B:A good scientific research must go through a" peer review". C:Peer review can be done by the researchers who do the experiment. D:An the existent brain trainer products have a peer review to testify their quality.
