单选题. All the evil in this world is brought about by persons who are always up and doing, but do not know when they ought to be up nor what they ought to be doing. The devil, I take it, is still the busiest creature in the universe, and I can quite imagine him denouncing (谴责) laziness and becoming angry at the smallest waste of time. In his kingdom, I will bet, nobody is allowed to do nothing, not even for a single afternoon. The world, we all freely admit, is in a mess, but I for one do not think that it is laziness that has brought it to that condition. It is not the active virtues that it lacks but the passive ones; it is capable of anything but kindness and a little steady thought. There is still plenty of energy in the world (there never were more fussy people about), but most of it is simply misdirected. If, for example, in July 1914, when there was some capital idling weather, everybody, emperors, kings, archdukes (大公爵), statesmen, generals, journalists, had been suddenly smitten (迷惑) with an intense desire to do nothing, just to hang about in the sunshine and consume tobacco, then we should all have been much better off than we are now. But no, the doctrine of the strenuous (艰苦的) life still went unchallenged; there must be no time wasted; something must be done. And, as we know, something was done. Again, suppose our statesmen, instead of rushing off to Versailles (凡尔赛宫) with a bundle of ill-digested notions and a great deal of energy to dissipate, had all taken a fortnight off, away from all correspondence and interviews and what not, and had simply lounged about on some hillside or other, apparently doing nothing for the first time in their energetic lives, then they might have gone to their so-called Peace Conference and come away again with their reputations still unsoiled and the affairs of the world in good trim. Even at the present time, if half the politicians in Europe would abandon the notion that laziness is a crime and go away and do nothing for a little space, we should certainly gain by it. Other examples come crowding into the mind. Thus, every now and then, certain religious sects (派别) hold conferences, but though there are evils abroad that are mountains high, though the fate of civilization is still doubtful, the members who attend these conferences spend their time condemning the length of ladies' skirts and the noisiness of dance bands. They would all be better employed lying flat on their backs somewhere, staring at the sky and recovering their mental health.1. In the author's opinion, being busy ______.

单选题. The public must be able to understand the basics of science to make informed decisions. Perhaps the most dramatic example of the negative consequences of poor communication between scientists and the public is the issue of climate change, where a variety of factors, not the least of which is a breakdown in the transmission of fundamental climate data to the general public, has contributed to widespread mistrust and misunderstanding of scientists and their research. The issue of climate change also illustrates how the public acceptance and understanding of science (or the lack of it) can influence governmental decision-making with regard to regulation, science policy and research funding. However, the importance of effective communication with a general audience is not limited to hot issues like climate change. It is also critical for socially charged neuroscience issues such as the genetic basis for a particular behavior, the therapeutic potential of stem cell therapy for neurodegenerative diseases, or the use of animal models, areas where the public understanding of science can also influence policy and funding decisions. Furthermore, with continuing advances in individual genome (基因组) sequencing and the advent of personalized medicine, more non-scientists will need to be comfortable analyzing complex scientific information to make decisions that directly affect their quality of life. Science journalism is the main channel for the popularization of scientific information among the public. Much has been written about how the relationship between scientists and the media can shape the efficient transmission of scientific advances to the public. Good science journalists are specialists in making complex topics accessible to a general audience, while adhering to scientific accuracy. Unfortunately, pieces of science journalism can also oversimplify and generalize their subject material to the point that the basic information conveyed is obscured or at worst, obviously wrong. The impact of a basic discovery on human health can be exaggerated so that the public thinks a miraculous cure is a few months to years away when in reality the significance of the study is far more limited. Even though scientists play a part in transmitting information to journalists and ultimately the public, too often the blame for ineffective communication is placed on the side of the journalists. We believe that at least part of the problem lies in places other than the interaction between scientists and members of the media, and exists because for one thing we underestimate how difficult it is for scientists to communicate effectively with a diversity of audiences, and for another most scientists do not receive formal training in science communication.1. What does the example of climate change serve to show? ______
