A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”. This idea is dangerous.

Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing.

Some people go even further. They say that despite the moral and legal objections （反对）, whatever is scientifically possible will be done ——somewhere, sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it a fuels sense of  hopelessness and discourages them from making efforts to build a safer world.

In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of “controlling” science in this century will be really tough. Take human cloning for example.

A lazy Susan is an addition to a table, which is designed to assist in moving food from one person to another while dining. This is accomplished through the use of a turntable(转盘), which usually moves the food in a circle when pushed by those at table. In this way, the food never has to be picked up and passed around the table. Instead, it remains in place as the lazy Susan is turned about.
A lazy Susan may also be a part of a kitchen cabinet. One may spin the lazy Susan in order to find certain goods stored in it. From the outside, a lazy Susan appears to be two cabinets. When one of these cabinets is pushed, however, both doors move and the lazy Susan is revealed inside.
Whether the lazy Susan is on a tabletop or within a cabinet, it can be made of a variety of materials. Most commonly, a lazy Susan is made of either plastic, wood or glass. Some people believe that Thomas Jefferson invented the lazy Susan, though it was referred to as a dumb waiter(上菜升降架) at that time. It is said that Jefferson invented the lazy Susan because his daughter complained she was always served last at table and, as a result, never found herself full when leaving the table. Others believe that Thomas Edison was the inventor, as he is believed to have invented the turntable for his phonograph(留声机), which later developed into the lazy Susan.
Regardless of who invented it, it wasn’t until 1917 that the term lazy Susan was created in an advertisement for the invention. In Britain, however, the term dumb waiter is still used rather than the term lazy Susan. The reason for the name lazy Susan remains a mystery. One theory is that it was named after either Jefferson’s or Edison’s daughter, both of whom were named Susan.

We can achieve knowledge either actively or passively（被动地）．We achieve it actively by direct experience, by testing and proving an idea, or by reasoning.
We achieve knowledge passively by being told by someone else．Most of the learning that takes place in the classroom and the kind that happens when we watch TV or read newspapers or magazines is passive．Conditioned as we are to passive learning, it’s not surprising that we depend on it in our everyday communication with friends and co-workers.
Unfortunately, passive learning has a serious problem．It makes us tend to accept what we are told even when it is little more than hearsay and rumor（谣言）.
Did you ever play the game Rumor? It begins when one person writes down a message but doesn’t show it to anyone．Then the person whispers it, word for word, to another person．That person, in turn, whispers it to still another, and so on, through all the people playing the game．The last person writes down the message word for word as he or she hears it．Then the two written statements are compared．Typically, the original message has changed.
That’s what happens in daily life．The simple fact that people repeat a story in their own words changes the story．Then, too, most people listen imperfectly．And many enjoy adding their own creative touch to a story, trying to improve on it, stamping（打上标记）it with their own personal style．Yet those who hear it think they know.
This process is also found among scholars and authors: A statement of opinion by one writer may be re-stated as fact by another, who may in turn be quoted by yet another; and this process may continue, unless it occurs to someone to question the facts on which the original writer based his opinion or to challenge the interpretation he placed upon those facts.
49．According to the passage, passive learning may occur in _______.
A．doing a medical experiment        B．solving a math problem
C．visiting an exhibition          D．doing scientific reasoning
50．The underlined word “it” in Paragraph 2 refers to _____.
A．active learning     B．knowledge     C．communication    D．passive learning
51．The author mentions the game Rumor to show that _____.
A．a message may be changed when being passed on
B．a message should be delivered in different ways
C．people may have problems with their sense of hearing
D．people tend not to believe in what they know as rumor
52．What can we infer from the passage?
A．Active learning is less important.
B．Passive learning may not be reliable.
C．Active learning occurs more frequently.
D．Passive learning is not found among scholars.
