年仅10周岁的小张发明了“水变油”的方法，下列说法中，不正确的有( )。
A．小张智力超常应当视为完全行为能力人
B．小张的发明行为属于事实行为
C．小张属于限制行为能力人
D．小张可以从事与其年龄、智力相适应的民事活动
参考答案：A
解析： (1)选项A：自然人的行为能力跟年龄和精神状态有关，和智力无关；(2)选项B：发明行为不需要进行意思表示，属于事实行为；(3)选项C：10周岁以上(≥10周岁)的未成年人是限制行为能力人，小张已经10周岁了，属于限制行为能力人；(4)选项D：限制行为能力人可以从事与其年龄、智力相适应的民事活动，从事超越其行为能力范围的事项应当由法定代理人进行代理或征得其法定代理人的同意。
Directions: There are 4 passages in this part. Each of the passages is followed by ,5 questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. Choose the best one and mark your answer on the ANSWER SHEET with a single line through the center.
Passage One
| In science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. A good example of this is found in the kinetic (运动的) molecular theory, in which gases are pictured as being made up of many small particles that are in constant motion. A useful theory, in addition to explaining past observations, helps to predict events that have not as yet been observed. After a theory has been publicized, scientists design experiments to test the theory. If observations confirm the scientists’ predictions, the theory is supported. If observations do not confirm the predictions, the scientists must search further. There may be a fault in the experiment, or the theory may have to be revised or rejected. Science involves imagination and creative thinking as well as collecting information and performing experiments. Facts by themselves are not science. As the mathematician Jules Henri Poincare said: "Science is built with facts just as a house is built with bricks, but a collection of facts cannot be called science anymore than a pile of bricks can be called a house. " Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been gathered, the scientist comes to the part of the investigation that requires considerable imagination. Possible solutions to the problem are formulated. These possible solutions are called hypotheses. In a way, any hypothesis is a leap into the unknown. It extends the scientist’s thinking beyond the known facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. For without hypotheses, further investigation lacks purpose and direction. When hypotheses are confirmed, they are incorporated into theories. |
In the last paragraph, the author refers to a hypothesis as "a leap into the unknown" in order to show that hypotheses ______.
A．require effort to formulate
B．can lead to dangerous results
C．go beyond available facts
D．are sometimes ill-conceived
