Last autumn, Jerald Schutte of California State University in Northridge divided a class of 33 students taking his course in statistics into two groups. The “traditional” group was taught in a classroom every Saturday morning for 14 weeks. The “on-line” group came together only for examinations at the start and end of the course. None of the students in either group knew they were part of an experiment. The online group used electronic mail to cooperate in groups of three, assigned casually. They also took part in weekly discussions held on the Internet and weekly “live” online talk session regulated by Schutte. At the end of the course, the on-line students scored 20 per cent higher in their exam. A subsequent questionnaire indicated that they had spent more time on their coursework, and that they understood the material better. Schutte attributes the virtual students’ success to their eagerness to discuss their work on-line. The traditional students tended to work in isolation. “I would say the cooperation resulted from being afraid of having no face-to-face interaction with a professor,” Schutte says. He does not think that the on-line students became more enthusiastic simply because of the novelty of working with the Internet, “most of that gave way to discouragement due to the technology problems.” “We believe you can’t dispose of the help of a teacher, at least in schools,” says Jeff Morgan, director of communications technologies at the UK National Council for Educational Technology, “though the results are perfectly reasonable for university-age students.”
(1)Schutte’s experiment focuses on the use of on-line education ___
A、as a substitute for conventional teaching
B、in support of conventional teaching
C、as an improvement of conventional teaching
D、as a part of conventional teaching
(2)On-line education is different from the traditional one in that _
A、it does not need any teachers
B、students work alone
C、there is much cooperation among students
D、exams are taken on-line
(3)The on-line group do better than the traditional group because _
A、they work together through the Internet
B、they are interested in the Internet
C、they want to do better than the “traditional” group
D、they don’t like the traditional teaching
(4)The result of the study shows that _
A、students can learn without teachers
B、learning at home is better than attending courses in the classroom
C、working on technology problems creates enthusiasm for students
D、advanced technology can enhance learning
(5)Jeff Morgan’s attitude toward the on-line teaching is ___
A、pessimistic
B、positive
C、neutral
D、critical

The California lawmakers voted Thursday to raise the legal age to buy tobacco products from 18 to 21. The measure is part of a larger package of laws aimed at reducing tobacco use. If Gover-nor Jerry Brown signs the bill, California will become the second state, after Hawaii, to raise the age limit for buying cigarettes and other tobacco products. More than 100 cities in the U. S., inclu-ding New York and Boston, have already raised the age limit.
A week ago, the Caiifomia Assembly approved the measure, which--in addition to raising the age limit--treats electronic cigarettes the same as tobacco products, expands smoke-free areas, in-creases smoking bans and allows counties to collect higher taxes on cigarettes than the 87-cent per pack state tax. The Assembly&39; s vote came a few days after the city of San Francisco increased the age to buy tobacco products to 21.
California lawmakers passed the bill despite lobbying (游说)from tobacco interests. The meas-ure also faced opposition from many Republicans, who said the state should not be involved in po-licing people&39; s personal choices. "I don&39; t smoke. I don&39; t encourage my children to," said Re-publican Assemblyman Donald Wagner. "But they&39; re adults, and it&39; s our job to treat our citizens as adults. "
But supporters of the bill say raising the age to 21 moves legally purchased tobacco that much farther from younger kids. " This will save the medical system millions of dollars," said Democratic Assemblyman Jim Wood. (76 ) "It will save thousands of lives. " A 2015 study by the Institute of Medicine "found that if the minimum legal age to buy tobacco were raised to 21 nation-wide, tobacco use would drop by 12 percent by the time today&39; s teens reached adulthood. In addi-tion, there would be 223,000 fewer premature (过早的) deaths and 50,000 fewer deaths from lung cancer. "
Which of the following is the first state to raise smoking age to 21？
A.California
B.Hawaii
C.New York.
D.Washington.
The California law includes all the following measures EXCEPT__________.A.enlarging no-smoking areas
B.allowing counties to collect higher taxes on cigarettes
C.increasing smoking bans
D.punishing parents who encourage their children to smoke
The word policing in Paragraph 3 probably means__________.A.enriching
B.controlling
C.understanding
D.protecting
Who is against the bill？A.Governor Jerry Brown.
B.Assemblyman Donald Wagner.
C.Assemblyman Jim Wood
E.The mayor of San Francisco.
Which of the following is an appropriate title for the passage？A.Calitbrnia Lawmakers Vote to Raise Smoking Age to 21
B.San Francisco Increased the Age to Buy Tobacco Products to 21
C.Hawaii Has Already Raised the Age Limit to Buy Tobacco
D.A California Bill Faces Opposition from Many Republicans

第8题

The Security Council is the most powerful body in the UN. It is responsible for maintaining international peace, and for restoring peace when conflicts arise. Its decisions are binding on all UN members. The Security Council has the power to define what is a threat to security, to determine how the UN should respond, and to enforce its decisions by ordering UN members to take certain actions. The Council convenes（召集）any time there is a threat to peace. A representative from each member country who sits on the Council must be available at all times so that the Council can meet at a moment’s notice. The Security Council also frequently meets at the request of a UN member - often a nation with a grievance about another nation’s actions.
The Security Council has 15 members; five of which hold permanent seats. The Assembly elects the other ten members for two-year terms. The five permanent members - the United States, Britain, France, Russia (formerly the Soviet Union), and China - have the most power. These nations were the winning powers at the end of World War II, and they still represent the bulk of the world’s military might. Decisions of the Council require nine votes. But any one of the permanent members can veto an important decision. This authority is known as the veto right of the great powers. As a result, the Council is effective only when its permanent members can reach a consensus（一致同意）.
The Council has a variety of ways it can try to resolve conflicts among countries. Usually the Council’s first step is to encourage the countries to settle their disagreements without violence. The Council can mediate a dispute or recommend guidelines for a settlement. It can send peacekeeping troops into a distressed area. If war breaks out, the Council can call for a ceasefire. It can enforce its decisions by imposing economic sanctions on a country, or through joint military action.
Which is TRUE in the following statements according to the passage？
A.The Security Council convenes annually.
B.All UN members should abide by the decisions adopted by the Security Council.
C.Although one member seriously complains about another member’s action, the Security Council will not convene at its request.
D.The five permanent members of the Security Council hold less than one half armed forces in the world.
The Security Council is effective only when its permanent members can reach a consensus because ____.A.every permanent member has the veto right of great powers
B.all the permanent members won in the World War II
C.the other members of the Security Council are in the charge of the permanent members
D.of some other reasons not mentioned in this passage
One motion（提议）is adopted by the Security Council only if ____.A.14 of 15 members accept this motion
B.all the members have no objection to the motion
C.9 members agree on it and all the permanent members approve of it
D.all the permanent members pass it
The passage introduces all things about the Security Council EXCEPT____.A.mission
B.membership
C.rights
D.history
The last paragraph of this passage may be concluded with the statement that ____.A.UN gives priority to peaceful settlement of the conflicts among countries
B.the peacekeeping troops are most powerful in the conflicts between countries
C.economic sanction will be imposed on the countries involved in war
D.joint military action is the last resort of the Security Council in dealing with conflicts between among countries

第9题

Just how much does the Constitution protect your digital data？ The Supreme Court will now consider whether police can search the contents of a mobile phone without a warrant if the phone is on or around a person during an arrest.
California has asked the justices to refrain from a sweeping ruling particularly one that upsets the old assumption that authorities may search through the possessions of suspects at the time of their arrest. It is hard, the state argues, for judges to assess the implications of new and rapidly changing technologies. The court would be recklessly modest if it followed California’s advice. Enough of the implications are discernable, even obvious, so that the justices can and should provide updated guidelines to police, lawyers and defendants.
They should start by discarding California’s lame argument that exploring the contents of a smart phone — a vast storehouse of digital information — is similar to, say, rifling through a suspect’s purse. The court has ruled that police don’t violate the Fourth Amendment when they sift through the wallet or pocketbook of an arrestee without a warrant. But exploring one’s smart phone is more like entering his or her home. A smart phone may contain an arrestee’s reading history, financial history, medical history and comprehensive records of recent correspondence. The development of “cloud computing,” meanwhile, has made that exploration so much the easier.
Americans should take steps to protect their digital privacy. But keeping sensitive information on these devices is increasingly a requirement of normal life. Citizens still have a right to expect private documents to remain private and protected by the Constitution’s prohibition on unreasonable searches.
As so often is the case, stating that principle doesn’t ease the challenge of line-drawing. In many cases, it would not be overly onerous for authorities to obtain a warrant to search through phone contents. They could still invalidate Fourth Amendment protections when facing severe, urgent circumstances, and they could take reasonable measures to ensure that phone data are not erased or altered while a warrant is pending. The court, though, may want to allow room for police to cite situations where they are entitled to more freedom.
But the justices should not swallow California’s argument whole. New, disruptive technology sometimes demands novel applications of the Constitution’s protections. Orin Kerr, a law professor, compares the explosion and accessibility of digital information in the 21st century with the establishment of automobile use as a virtual necessity of life in the 20th: The justices had to specify novel rules for the new personal domain of the passenger car then; they must sort out how the Fourth Amendment applies to digital information now.
26. The Supreme Court will work out whether, during an arrest, it is legitimate to
A.prevent suspects from deleting their phone contents.
B.search for suspects’ mobile phones without a warrant.
C.check suspects’ phone contents without being authorized.
D.prohibit suspects from using their mobile phones.
The author’s attitude toward California’s argument is one ofA.disapproval
B.indifference
C.tolerance
D.cautiousness
The author believes that exploring one’s phone contents is comparable toA.principles are hard to be clearly expressed
B.the court is giving police less room for action
C.citizens’ privacy is not effectively protected
D.phones are used to store sensitive information
Orin Kerr’s comparison is quoted to indicate thatA.the Constitution should be implemented flexibly
B.new technology requires reinterpretation of the Constitution
C.California’s argument violates principles of the Constitution.
D.principles of the Constitution should never be altered
The author believes that exploring one’s phone contents is comparable toA.getting into one’s residence
B.handling one’s historical records
C.scanning one’s correspondences
D.going through one’s wallet

NASA, the U.S. space agency, believes there's a good chance that we're not alone

NASA, the U.S. space agency, believes there's a good chance that we're not alone in the universe. Last fall, NASA began a new project called the High Resolution Microwave Survey (HRMS). Its aim: to find evidence of life in one of the billions of galaxies in the universe.

The search for intelligent life on other planets isn't new. It began almost 100 years ago. That's when scientists built a huge transmitter to send radio waves into space. Scientists thought smart beings on other planets might pick up the signals.

Scientists also have sent a message about humans and our solar system to a nearby constellation (星座 ). But because the constellation is 25,000 light years away, a return message wouldn't reach Earth for 50,000 years! So don't wait up for an answer.

So far, no extraterrestrial (地球外的 ) beings that we know of have returned our “ calls. ” But according to Dr. Jill Tarter, an HRMS scientist, we haven't exactly had our ears wide open. “ Now, however, ” says Dr. Tarter, “ we've built the tools we need to listen well.”

Last October, Dr. Tarter switched on the largest radio receiver in the world. It's an enormous metal bowl stretching 1,000 feet across a valley in Puerto Rico.

Meanwhile, another NASA scientist turned on a huge radio receiver in California's Mojave Desert. NASA hopes these big dishes-and others around the world-will pick up radio signals from new world.

Dr. Frank Drake has been searching for life in outer space for years. He explains the HRMS project this way: To listen to your radio, you move the tuner on the dial until the channels come in loud and clear: Now imagine radio receivers that scan our galaxy “listening” to 14 million channels every second. That's what NASA's radio receivers in Puerto Rico and California are doing.

But that's not all. Powerful computers hooked to the receivers examine every signal carefully. The computers try to match the signals to ones that scientists already recognize, such as human-made signals. If they can't, Drake and Tarter check on them. “It could prove there is radio technology elsewhere in the universe, ” says Dr. Tarter. “ And that would mean we're not alone. ” 26、NASA scientists started a new project in order to _______.

A、discover life in other galaxies

B、send human beings into space

C、find evidence of a new galaxy

D、confirm the number of galaxies

27、According to Dr.Jill Tarter ,the reason why we haven't received any return any return messages from outer space is that_______.

A、our ears are not sharp enough to hear them

B、our equipment hasn't been good enough

C、it takes millions of yuars for them to reach us

D、it takes quite a long time to send them

28、Dr.Jill Tarter compares the large receiver to _______.

A、the human ear

B、the universe

C、a metal bowl

D、a huge dish

29、According to Dr.Frank Drake ,NASA's radio receivers in Puerto Rico and California are _______.

A、trying to check on every channel carefully

B、moving the tuner on the dial for clear channels

C、scanning the universe for possible signals

D、picking up radio signals from new world

30、The best title of this passage is ________.

A、Signals from the Space

B、The Invention of New Radio Receivers

C、The Intelligent Life in Outer Space

D、NASA Listens for Space Neighbors
