Previously, the sack-like rabbit appendix was thought to serve primarily as a reservoir for the bacteria involved in hindgut fermentation, an explanation that failed to account for the absence of an appendix in other animals with Line similar digestive systems or for its presence in humans. Microscopic research (5) revealed that the appendix contains a significant amount of lymphoid tissue,similar aggregates of which tissue occur in other areas of the gastrointestinal tract. These are involved, possibly, in the body’s ability to recognize foreign antigens in ingested material, but the evidence is inconclusive, to the extent that scientists have long discounted the human appendix as a "vestigial" organ. (10) However, a growing body of evidence suggests that the appendix, far from being a "vestigial organ", has a significant function as a part of the body’ s immune system. The appendix achieves its greatest development shortly after birth, when immune response is first developing, then regresses with age,when the immune response mediated by the appendix may relate to such (15) inflammatory conditions as ulcerative colitis, which in adults necessitates the organ’s surgical removal. The passage provides information in support of which of the following assertions（）

Most words are "lexical words", i.e. nouns signifying "things", the majority of which are abstract concepts rather than physical objects in the world; only "proper nouns" have specific and unique referents in the everyday Line world. The communicative function of a fully-functioning language requires the (5) scope of reference beyond the particularity of the individual instance. While each leaf, cloud or smile is different from all others, effective communication requires general categories or "universals". Anyone who has attempted to communicate with people who do not share their language will be familiar with the limitations of simply pointing to things, given that the vast majority of (10) lexical words in a language exist on a high level of abstraction and refer to classes of things such as "buildings" or to concepts like "construction".We lose any one-to-one correspondence of word and thing the moment we group instances into classes. Other than lexical words, language consists of "function words" or grammatical words, such as "only" and "under" which do (15) not refer to objects in the world at all, and many more kinds of signs other than simple nouns. The notion of words as labels for concepts assumes that ideas exist independently of words and that ideas are established in advance before theintroduction of linguistic structure. Clearly, language is not limited to naming things existing in the physical world, but includes non-existent objects and ideas (20) well. The nomenclaturist stance, in viewing words as labels for pre-existingideas and objects, attempts unsuccessfully to reduce language to the purely referential function of naming things. Things do not exist independently of the sign systems which we use; "reality" is created by the media which seem simply(25) to represent it. Language does not simply name pre-existing categories; categories do not exist in "the world" .e.g. "where are the boundaries of a cloud; when does a smile begin". Such an emphasis on reality as invariably perceptually seamless may be an exaggeration; our referential categories do seem to bear some relationship to certain features which seem to be inherently (30) salient. Within a language, many words may refer to "the same thing" but reflect different evaluations of it. For example, "one person’s ’hovel’ is another person’s ’home’" Meanwhile, the signified of a word is subject to historical change. In this sense, "reality" or "the world" is created by the language we use: this (35) argument insists on the primacy of the signifier. Even if we do not adopt the radical stance that "the real world" is a product of our sign systems, we must still acknowledge the lack of signifiers for many things in the empirical world and that there is no parallel correlation between most words and objects in the known world at all. Thus, all words are "abstractions", and there is no direct (40) correspondence between words and "things" in the world. According to the passage, which of the following assumptions would the "nomenclaturist" most likely agree with（）

Pollution: A Life and Death Issue One of the main themes of Planet under Pressure is the way many of the Earth’s environmental crises reinforce one another. Pollution is an obvious example—we do not have the option of growing food, or finding enough water, on a squeaky- clean planet, but on one increasingly tarnished and trashed by the way we have used it so far. Cutting waste and clearing up pollution cost money. Yet time and again it is the quest for wealth that generates much of the mess in the first place. Living in a way that is less damaging to the Earth is not easy, but it is vital, because pollution is pervasive and often life-threatening. Air: the World Health Organization (WHO) says three million people are killed worldwide by outdoor air pollution annually from vehicles and industrial emissions, and 1.6 million indoors through using solid fuel. Most are in poor countries. Water: diseases carried in water are responsible for 80% of illnesses and deaths in developing countries, killing a child every eight seconds. Each year 2.1 million people die from diarrhoeal(痢疾的) diseases associated with poor water. Soil: contaminated land is a problem in industrialized countries, where former factories and power stations can leave waste like heavy metals in the soil. It can also occur in developing countries, sometimes used for dumping pesticides. Agriculture can pollute land with pesticides, nitrate-rich fertilizers and slurry from livestock. And when the contamination reaches rivers it damages life there, and can even create dead zones off the coast, as in the Gulf of Mexico.Chronic Problem Chemicals are a frequent pollutant. When we think of chemical contamination it is often images of events like Bhopal that come to mind. But the problem is widespread. One study says 7-20% of cancers are attributable to poor air and pollution in homes and workplaces. The WHO, concerned about chemicals that persist and build up in the body, especially in the young, says we may "be conducting a large-scale experiment with children’s health". Some man-made chemicals, endocrine(内分泌) disruptors like phthalates(酞酸盐) and nonylphenol—a breakdown product of spermicides (杀精子剂), cosmetics and detergents—are blamed for causing changes in the genitals of some animals. Affected species include polar bears—so not even the Arctic is immune. And the chemicals climb the food chain, from fish to mammals, and to us. About 70,000 chemicals are on the market, with around 1,500 new ones appearing annually. At least 30,000 are thought never to have been comprehensively tested for their possible risks to people. At first glance, the plastic buckets stacked in the comer of the environmental NGO office took like any others. But the containers are an unlikely weapon in one poor community’s fight against oil companies which they say are responsible for widespread ill-health caused by years of pollution. The vessels are used by a network of local volunteers, known as the Bucket Brigade, to gather air samples in neighborhoods bordering oil refineries, as part of a campaign to monitor and document air pollution which they believe is coming from the plants. In South Africa, as in many developing and newly industrialized countries, legislation on air pollution has failed to keep pace with mushrooming industries. So local residents, like many in poor communities around the globe, have faced the problem of investigating their claim that industries on their doorsteps are making them sick.Trade-off But the snag is that modem society demands many of them, and some are essential for survival. So while we invoke the precautionary principle, which always recommends erring on the side of caution, we have to recognize there will be trade-offs to be made. The pesticide DDT does great damage to wildlife and can affect the human nervous system, but can also be effective against malaria(疟疾). Where does the priority lie The industrialized world has not yet cleaned up the mess it created, but it is reaping the benefits of the pollution it has caused. It can hardly tell the developing countries that they have no right to follow suit. Another complication in tackling pollution is that it does not respect political frontiers. There is a U.N. convention on trans-boundary air pollution, but that cannot cover every problem that can arise between neighbors, or between states which do not sham a border, perhaps the best example is climate change—the countries of the world share one atmosphere, and what one does can affect everyone.For One and All One of the principles that are supposed to apply here is simple—the polluter pays. Sometimes it is obvious who is to blame and who must pay the price, but it is not always straightforward to work out just who is the polluter, or whether the rest of us would be happy to pay the price of stopping the pollution. One way of cleaning up after ourselves would be to throw less away, designing products to be recycled or even just to last longer. Previous generations worked on the assumption that discarding our waste was a proper way to get rid of it, so we used to dump nuclear materials and other potential hazards at sea, confident they would be dispersed in the depths. We now think that is too risky because, as one author wrote, "there’s no such place as ’away’, and there’s no such person as the ’other’."Irritating Air Despite recent improvements, however, the health problems are still there. A 2002 medical study, carried out by Durban’s Nelson Mandela School of Medicine and a U.S. university, found that an abnormally high 52% of students and teachers at a primary school bordering the Engen plant suffered from asthma (哮喘). It found that increases in air pollution tended to aggravate asthma symptoms in children. The petrol producers do not dispute the findings but argue that researchers were Unable to establish a Causal link between air pollution and the high prevalence of asthma among the school population. For the community, the next step is to take legal action. But, according to internationally recognized environmentalist Bobby Peek, targeting the companies would ha difficult as it would be near-impossible to prove that illnesses suffered were caused by pollution coming from a particular plant. Mr. Peek, who grew up beneath Engen’s stacks, says the activists are now considering taking action against the authorities. "We are now looking at suing the government on constitutional grounds, for failing to ensure our right to protection from a harmful environment as stipulated in the constitution," he said.Legislative Change A new batch (批) of environmental laws, the National Air Quality Management Act, has just been passed by the South African parliament to replace outdated 1965 legislation with tighter controls and tougher sanctions. Martinus van Schalkwyk, the minister of environmental affairs and tourism, visited the south Durban basin earlier this year and said there were measures in place to improve the situation. "I share the anger and frustration of this community. It is long overdue," he told the South African Broadcasting Corporation. The local authorities have also established a "Multi-Point Plan" for the area. They say it is a powerful model for tackling pollution and points to a 40% reduction in sulphur dioxide emissions in recent years. What is not said to be a way of cleaning up after ourselves
