1、Section 2 Semantic Use of Words：Correct and Accurate in MeaningI. Key to the Exercise1. Whats the relationship between semantic use of words and word meaning? Does semantic use of words affect the meaning of what you write?Find out the answer from the lecture.2. What are the semantic traits of the i

2、talic words in the following dialogues?1) - I like all vegetables. What do you like? (Generic)一 I like only potatoes and tomatoes. (Specific)2) - I guess you are arot/nc/twenty. (Approximity in Meaning)-Yes, you are absolutely right I am twenty-one. (Extremely certain)3) - You say you live near the

3、bank. Then you can get a good job there. (Ambiguous)一 No. I mean I live near the bank of the river that runs across the city. (Clear)4) 一 I know I am quite miserly and stingy. (Derogatory)-No, you are being economical. (Commendatory)5) 一 Your father is a sanitation engineer, isnJt he? (Euphemistic)-

4、Yes, he is a garbage man in our community. (Literal)3. What are the two main categories of correct use of words?Find out the answer from the lecture.4. Are the following uses of words semantically correct?1) She is a southerner. She said she couldnl go without rice. (Correct)2) No one can live witho

5、ut rice. (Incorrect)3) We havent got any news from him for three years. Last week, he sent me an email (Correct)4) Yesterday we did some running. Today well have some exercise. (Incorrect- exercise should be change into “other types of exercise”)5) - Did she walk to the station last night? (Correct)

6、-Yes, she went to the station accompanied by one of her friend. (Incorrect： “went” is not used to the point how she went to the station 一 walk or go by transportation means)6) I was sure that she may not accept this offer. (Incorrect： uwas sure” and some medically relevant information in some cases,

7、 as for example “white” as opposed to uAfrican American,5 if the contrast is between Finland and West Africa, but not if it is a contrast between a “white” Mediterranean and an uAsian,5 Indian. There is a confusion here between race and ancestry. Sickle cell anemia is in high frequency not only in W

8、est Africans but also in some “white Middle Eastern and Indian populations. Moreover, a person with, say, one African great-grandparent, but who is identified by herself and others as “white“ has a one in eight chance of inheriting a sickle-cell mutation carried by that ancestor. There are, in addit

9、ion, a number of other simply inherited hemoglobin abnormalities, the thalassemias, that are in high frequency in some places in the Mediterranean (Sardinia), Arabia and southeast Asia. The highest frequency known for a thalassemia (80%) is in Nepal, but it is rare in most of Asia. The categorizatio

10、n of individuals simply as “white” or “Afro-American” or “Asian” will result in a failure to test for such abnormal hemoglobins because these abnormalities do not characterize the identified “race” of the patient. Even group identities below the level of the conventional races are misleading. Two of

11、 my incontrovertibly WASP grandchildren have a single Ashenazi Jewish great-grandparent and so have a one in eight chance of inheriting a Tay-Sachs abnormality carried by that ancestor. For purposes of medical testing we do not want to know whether a person is “Hispanic but rather whether that perso

12、ns family came from a Caribbean country such as Cuba, that had a large influx of West African slaves, or one in which there was a great deal of intermixture with native American tribes as in Chile and Mexico, or one in which there was only a negligible population of non-Europeans. Racial identificat

13、ion simply does not do the work needed. What we ought to ask on medical questionnaires is not racial identification, but ancestry. “Do you know of any ancestors who were (Ashkenazi Jews, or from West Africa, from certain regions of the Mediterranean, from Japan)?” Once again, racial categorization i

14、s a bad predictor of biology.There has been an interesting dialectic between the notion of human races and the use of race as a general biological category. Historically, the concept of race was imported into biology, and not only the biology of the human species, from social practice. The conscious

15、ness that human beings come in distinct varieties led, in the history of biology, to the construction of “race” as a subgrouping within species. For a long time the category “race” was a standard taxonomic level. But the use of “race” in a general biological context then reinforced its application t

16、o humans.After all, lots of animal and plant species are divided into races, so why not Homo sapiens? Yet the classification of animal and plant species into named races was at all times an ill-defined and idiosyncratic practice. There was no clear criterion of what constituted a race of animals or

17、plants that could be applied over species in general. The growing realization in the middle of the twentieth century that most species had some genetic differentiation from local population to local population led finally to the abandonment in biology of any hope that a uniform criterion of race cou

18、ld be constructed. Yet biologists were loathe to abandon the idea of race entirely. In an attempt to hold on to the concept while make it objective and generalizable, Th. Dobzhansky, the leading biologist in the study of the genetics of natural populations, introduced the geographical race,n which h

19、e defined as any population that differed genetically in any way from any other population of the species. But as genetics developed and it became possible to characterize the genetic differences between individuals and populations it became apparent, that every population of every species in fact d

20、iffers genetically to some degree from every other population. Thus, every population is a separate “geographic racen and it was realized that nothing was added by the racial category. The consequence of this realization was the abandonment of “race” as a biological category during the last quarter

21、of the twentieth century, an abandonment that spread into anthropology and human biology. However, that abandonment was never complete in the case of the human species. There has been a constant pressure from social and political practice and the coincidence of racial, cultural and social class divi

22、sions reinforcing the social reality of race, to maintain “race” as a human classification. If it were admitted that the category of trace is a purely social construct, however, it would have a weakened legitimacy. Thus, there have been repeated attempts to reassert the objective biological reality

23、of human racial categories despite the evidence to the contrary.3.

Supplementary Sample (4)Why We Use Scientific Names of PlantsNicknames

34、Easier to Pronounce, But ImpreciseBy David Beaulieu, A GuideWhy do we use those hard-to-pronounce scientific names of plants? Is it out of smugness? Wouldnt it be more democratic to use the common monikers (or nicknames) that everyone can understand, instead of the scientific names of plants?Ironica

35、lly, thats just the point: Not everyone can understand what particular specimens are being referred to by those charming old nicknames. The latter vary not only from language to language, but even from region to region. Thus we inject too much confusion into the discussion when we forgo using scient

36、ific names of plants in favor of their nicknames. In fact, even with n the same region a specimen may well have more than one nickname attributed to it. Or in some cases, none exists at all for a given specimen. Worse yet, two specimens quite unrelated may share the exact same nickname!Scientific Na

37、mes of Plants to the Rescue!It was to combat such confusion that Swedish naturalist Carolus (Carl) Linnaeus (1707-1778) developed what is known as the binomial system for taxonomy - in other works, the use of scientific names for plants. Binomiar* means that two words are used for classification pur

38、poses, and those two words are in Latin (or Latinized, at least). You may remember from History class that Latin was once the universal language of Western scholars. And it is that very universality that is still relied upon to bring some clarity to the business of plant classification, in the form

39、of scientific names for plants. So if you plug Glechoma hederacea, for instance, into the Google search engine, by about the fourth page of results youll see that some of the entries are in languages other than English. Thafs universality for you, and thafs the beauty of the scientific names of plan

40、ts.Speaking of Glechoma hederacea, the weed to which it refers with such clarity provides a wonderful example of the superiority of scientific names of plants over their common counterparts. For Glechoma hederacea has enough nicknames attached to it to make your head spin! One of them is creeping Ch

41、arlie. But to get some indication of how confusing it can be to forgo scientific names of plants in favor of nicknames, see my article on creeping Charlie, which also relates some of the history on this storied yet obscure weed.Pronunciation of the Scientific Names of PlantsBut admittedly, the pronu

42、nciation of the scientific names of plants is another matter altogether. For the pronunciation of the scientific names of plants can be downright confusing! And the confusion is exacerbated by the fact that, in some cases, there is more than one proper pronunciation for the word. Thus you can go you

43、r whole life hearing the certain (and proper) pronunciations of the scientific names of plants, only to encounter other (equally proper) pronunciations that leave you scratching your head.Below I have compiled a list of 10 scientific names of plants with problematic pronunciations. These entries mak

44、e the list either because they are widely mispronounced, or because they frustrate us with the dual pronunciations to which I just alluded. Not all of the 10 scientific names of plants below are, strictly speaking, Latin; but where they are not, the word does at least derive from the Latin, which is

45、 the source of the confusion:Top 10 Difficult-to-Pronounce Scientific Names of Plants1. clematis: CLE-muh-tuhs or cle-MA-tuhs2. Peony: PE-uh-ne or pe-O-ne3. Cotoneaster: cuh-TO-ne-AS-tuhr (although even my dictionary gives some legitimacy to the mispronunciation, CAWT-tuhn-ES-tuhr)4. Poinsettia: poy

46、n-SEH-tuh or poyn-SEH-te-uh (Although we constantly hear the incorrect poynt-SEH-tuh.)5. Chamomile: KAM-uh-mil or KAM-uh-mel6. achillea: A-kuh-LE-a or a-KIH-le-uh7. lamium: LAY-me-uhm8. Lupine: LU-puhn (Although there is a word with the exact same spelling, pronounced LU-pin, which means pertaining

48、 encyclopediaPlant taxonomy is the science that finds, describes, classifies, identifies, and names plants. It thus is one of the main branches of taxonomy.Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two. In practice, plant systematics is involve

49、d with relationships between plants and their evolution, especially at the higher levels, whereas plant taxonomy deals with the actual handling of plant specimens. The precise relationship between taxonomy and systematics, however, has changed along with the goals and methods employed.Plant taxonomy is well k
