单选题{{B}}Directions:{{/B}} There are 5 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets. A man-made chemical that attracts male gypsy moths by duplicating the natural attractant of female gypsy moths has been patented as No. 3,018,219. Dr. Martin Jacobson of Silver Spring, Md., assigned patent rights to the U. S. Government as represented by the Secretary of Agriculture. The chemical can be used to detect gypsy moth infestations, as well as to control the insects. The gypsy moth does serious damage to forest and shade trees in New England and eastern New York State. The caterpillars, or larvae, of gypsy moths eat the leaves of trees, often causing death by a single attack. Losses of hardwood trees have been estimated at tens of millions of dollars from a 20-year study. Gypsy moths were prevented from spreading to other U. S. forest areas by using the natural attractant of the female to detect infestations, then spraying with chemicals such as DDT to kill the insects. Since the lure could previously be obtained only by clipping the last two abdominal segments of the virgin female moth, extracting the segments with benzene and then processing to stabilize the chemical, the procedure was expensive. Another difficulty was that, as the gypsy moth population declined, it became increasingly hard to obtain the females needed for lure production. Dr. Jacobson overcame both these difficulties by discovering a synthetic method for making the female's attractant chemical. The chemical is known as 12-acetoxy-l-hydroxycis-9- octadecene. It is so potent that the fraction of a drop produced by the female is 200,000 times more than the amount needed to catch a mate. The synthetic chemical is also very powerful--it works in amounts about equivalent to one drop in a box car. The flightless female gypsy moth mates only once a year and, as soon as she does, an enzyme switches off production of the sex attractant. The winged male, however, call mate several times and it is because of this that the chemical is being used for pest control. By using a mixture of attractant and DDT in traps lined with a sticky substance, enough males can be caught to reduce the gypsy moth population substantially.

单选题The Secretary of State ______ to being astonished at this unexpected statement.

单选题In little religious sects, accordingly, the morals of the common people have been almost always remarkably regular and orderly; generally much more so than in the established church. The morals of those little sects, indeed, have frequently been rather disagreeably rigorous and unsocial. There are two very easy and effectual remedies, however, by whose joint operation the state might, without violence, correct whatever was unsocial or disagreeably rigorous in the morals of all the little sects into which the country was divided. The flint of those remedies is the study of science and philosophy, which the state might render almost universal among all people of middling or more than middling rank and fortune; not by giving salaries to teachers in order to make them negligent and idle, but by instituting some sort of probation, even in the higher and more difficult sciences, to be undergone by every person before he was permitted to exercise any liberal profession, or before he could be received as a candidate for any honourable office of trust or profit. If the state imposed upon this order of men the necessity of learning, it would have no occasion to give itself any trouble about providing them with proper teachers. They would soon find better teachers for themselves than any whom the state could provide for them. Science is the great antidote to the poison of enthusiasm and superstition; and where all the superior ranks of people were secured from it, the inferior ranks could not be much exposed to it. The second of those remedies is the frequency and gaiety of public diversions. The state, by encouraging, that is by giving entire liberty to all those who for their own interest would attempt without scandal or indecency, to amuse and divert the people by painting, poetry, music, dancing, by all sorts of dramatic representations and exhibitions, would easily dissipate, in the greater part of them, that melancholy and gloomy humour which is almost always the nurse of popular superstition and enthusiasm. Public diversions have always been the objects of dread and hatred to all the fanatical promoters of those popular frenzies. The gaiety and good humour which those diversions inspire were altogether inconsistent with that temper of mind which was fittest for their purpose, or which they could best work upon. Dramatic representations, besides, frequently exposing their artifices to public ridicule, and sometimes even to public execration, were upon that account, more than all other diversions, the objects of their peculiar abhorrence. In a country where the law favoured the teachers of no one religion more than those of another, it would not be necessary that any of them should have any particular or immediate dependency upon the sovereign or executive power; or that he should have anything to do either in appointing or in dismissing them from their offices. In such a situation he would have no occasion to give himself any concern about them, further than to keep the peace among them in the same manner as among the rest of his subjects; that is, to hinder them from persecuting, abusing, or oppressing one another. But it is quite otherwise in countries where there is an established or governing religion. The sovereign can in this case never be secure unless he has the means of influencing in a considerable degree the greater part of the teachers of that religion.
