[不定项选择题]资料：The increasing amount of personal information that can be collected by computer programs that track how people use Facebook has been revealed by an extensive academic study.
Such programs can show undisclosed private information such as Facebook users' sexuality, drug-use habits and even whether their parents separated when they were young, according to the study by the University of Cambridge academics.
In one of the biggest studies of its kind scientists from the university’s team and a Microsoft-funded research center analyzed data from 58,000 Facebook users to predict traits and other information that were not provided in their profiles.
The algorithms were 88 per cent accurate in predicting male sexual orientation, 95 per cent for race and 80 per cent for religion .And political leanings, personality
types and emotional stability were also predicted with accuracy ranging from 62-75 per cent.
The study highlights growing concerns about social networks and how data trails can be mined for sensitive information even when people attempt to keep information about themselves private ：Less than 5 per cent of users were connected with explicitly gay groups.
Michal Kosinksi ，one of the report’s authors told the Financial Times that the university’s techniques could easily be replicated by companies to inter personal attributes a person did not wish to share such as sexual orientation or political views:”We used very simple and generic methods :Marketing companies and internet companies could spend much more time and resources and hence get much higher accuracy than we did.
The report also revealed some unexpected correlations such as people who liked ‘curly fries’ having higher IQs while those Who like Facebook’s “Sliding on Floors With Your Socks On”page were unlikely to use drugs.
According to Michal Kosinksi,which of the following is true according to the passage?
A.The study draws people’s attention for private information
B.information can be predicted correctly in the study
C.some personal information may be collected and used by some companies
D.if people attempt to keep personal information private, things will change

Space is a dangerous
place, not only because of meteors but also because of rays from the sun and
other stars. The atmosphere again acts as our protective blanket on earth. Light
gets through, and this is essential for plants to make the food which we eat.
Heat, too, makes our environment endurable. Various kinds of rays come through
the air from outer space, but enormous quantities of radiation from the sun are
screened off. As soon as men leave the atmosphere they are exposed to this
radiation but their space suits or the walls of their spacecraft, if they are
inside, do prevent a lot of radiation damage.
Radiation is the
greatest known danger to explorers in space. The unit of radiation is called
"rem". Scientists have reason to think that a man can put up with far more
radiation than 0.1 rem without being damaged; the figure of 60 rems has been
agreed on. The trouble is that it is extremely difficult to b

[单项选择]第一篇Energy and Public Lands
The United States boasts substantial energy resources. Federal lands provide a good deal of U.S. energy production; the U.S. Department of the Interior manages federal energy leasing, both on land and on the offshore Outer Continental Shelf. Production from these sources amounts to nearly 30 percent of total annual U.S. energy production.
In 2000, 32 percent of U.S. oil, 35 percent of natural gas, and 37 percent of coal were produced from federal lands, representing 20,000 producing oil and gas leases and 135 producing coal leases. Federal lands are also estimated to contain approximately 68 percent of all undiscovered U.S. oil reserves and 74 percent of undiscovered natural gas.
Revenues from federal oil, gas, and coal leasing provide significant returns to U.S. taxpayers as well as State governments. In 1999, for example, $553 million in oil and gas revenues were paid to the U.S. Treasury, and non-Indian coal leases accounted for over $304 million in rev
