It is very difficult to prove today that a painting done two or three hundred years ago, especially one without a signature or with a questionably authentic signature, is indubitably the work of this or that particular artist. This fact gives the traditional attribution of a disputed painting special weight, since that attribution carries the presumption of historical continuity. Consequently, an art historian arguing for a deattribution will generally convince other art historians only if he or she can persuasively argue for a specific reattribution. Which one of the following, if true, most strongly supports the position that the traditional attribution of a disputed painting should not have special weight?

A．Art dealers have always been led by economic self-interest to attribute any unsigned paintings of merit to recognized masters rather than to obscure artists.

B．When a painting is originally created, there are invariably at least some eyewitnesses who see the artist at work, and thus questions of correct attribution cannot arise at that time.

C．There are not always clearly discernible differences between the occasional inferior work produced by a master and the very best work produced by a lesser talent.

D．Attribution can shape perception inasmuch as certain features that would count as marks of greatness in a master"s work would be counted as signs of inferior artistry if a work were attributed to a minor artist.

E．Even though some masters had specialists assist them with certain detail work, such as depicting lace, the resulting works are properly attributed to the masters alone.

This incident occurred when a vessel carrying a【48】ca______of sugar was shipwrecked in 1793. The five【49】______(survive) sailors were finally rescued nine days after the accident. They were in a wasted condition due to starvation, having consumed nothing but【50】______.

French physiologist F. Magendie was inspired by that incident to【51】co______a series ofexperiments with【52】an______. In the experiments, he fed dogs a diet of sugar and water. All the dogs wasted and died.

The shipwrecked sailors and the French physiologist' s experimental dogs proved the same point. As a steady diet, sugar is worse than nothing. Plain water can keep you【53】a______for quite some time. Sugar and water can kill you. Humans and animals are "unable to subsist【54】______a diet of sugar". The dead dogs in Professor Magendie' s【55】la______alerted the sugar industry to the hazards of free scientific inquiry. From that day to this, the sugar industry has invested millions of dollars in behind-the-scenes, subsidized science. The best scientific names that money could buy have been hired, in the hope that they could one day come up with something at least pseudoscientific in the way of glad tidings about sugar.

第5题

There are two basic ways to see growth: one as a product, the other as a process. People have generally viewed personal growth as an external result or product that can easily be identified and measured. The worker who gets a promotion, the student whose grades improve, the foreigner who learns a new language — all these are examples of people who have measurable results to show for their efforts.

By contrast, the process of personal growth is much more difficult to determine, since by definition it is a journey and not the specific signposts or landmarks along the way. The process is not the road itself, but rather the attitudes and feelings people have, their caution or courage, as they encounter new experiences and unexpected obstacles. In this process, the journey never really ends; there are always new ways to experience the world, new ideas to try, new challenges to accept.

In order to grow, to travel new roads, people need to have a willingness to take risks, to confront the unknown, and to accept the possibility that they may "fail" at first. How we see ourselves as we try a new way of being is essential to our ability to grow. Do we perceive ourselves as quick and curious? If so, then we tend to take more chances and to be more open to unfamiliar experiences. Do we think we're shy and indecisive? Then our sense of timidity can cause us to hesitate, to move slowly, and not to take a step until we know the ground is safe. Do we think we're slow to adapt to change or that we're not smart enough to cope with a new challenge? Then we are likely to take a more passive role or not try at all.

These feelings of insecurity and self-doubt are both unavoidable and necessary if we are to change and grow. If we do not confront and overcome these internal fears and doubts, if we protect ourselves too much, then we cease to grow. We become trapped inside a shell of our own making.

A person is generally believed to achieve personal growth when ______.

A．he has given up his smoking habit

B．he has spared no efforts to help others

C．he is keen on learning a foreign language

D．he is studying very hard
