English has a large number of nouns which appear to be neutral with regard to sex, but actually ar

8、e covertly masculine. Although the dictionary may define poet as one who writes poetry, a woman who writes poetry appears so anomalous or threatening to some,that they use the special term poetess to refer to her. There is no corresponding term to call attention to the sex of a man who writes poetry

9、, but then we find nothing remarkable in the fact that poetry is written by men. Of course, if a woman is sufficiently meritorious, we may forgive her sex and refer to her as a poet after all, or, wishing to keep the important fact of her sex in our consciousness, we may call her a woman poet. Howev

10、er, to balance the possible reward of having her sex overlooked, there remains the possibility of more extreme punishment, we may judge her work so harshly that she will be labelled a lady poet. Once again, the moral is clear, people who write poetry are assumed to be men until proven otherwise, and

11、 people identified as women who write poetry are assumed to be less competent than sexually unidentified (i.e., presumably male) people who write poetry. If the phenomenon we have been discussing were limited to poetry, we might not regard it as very significant , after all, our society tends to reg

12、ard poets as some what odd anyway. But, in fact, it is wide spread in the language. There is a general tendency to label the exception, which in most cases turns out to be women. Many words with feminine suffixes, such as farmerette, authoress, and aviatrix, have such a clear trivializing effect, th

13、at there has been a trend away from their use and a preference for woman author and the like. The feminines of many ethnic terms, such as Negress and Jewess, are considered particularly objectionable. Other words, such as actress and waitress, seem to have escaped the negative connotations and remai

14、n in use. However, we note that waiters often work in more expensive establishments than do waitresses, that actresses belong to“ Actors Equity, “and that women participants in theatrical groups have begun to refer to themselves as “actors.“ on rare occasions, this presumption of maleness in terms w

15、hich should be sexually neutral, works to womens advantage. If someone is called a bastard, either as a general term of abuse, or as a statement of the lack of legal marital ties between that persons parents, we assume that person is a male. While an illegitimate child may be of either sex, only men

16、 are bastard in common usage. Although the dictionary seems to regard this as a sex-neutral term, a recent dictionary of slang gives the term bastard a definition as a “female bastard.“ （分数：-0.98）(1).The word “anomalous“ means ridiculous.（分数：-0.14）A.RightB.WrongC.Not Mentioned(2).This passage is fro

Most of us can find 15 minutes or half an hour each day for some specific regular activity. For example, one famous surgeon always made it a rule to spend at least 15 m

20、inutes on general reading before he went to sleep each day. Whether he went to bed at 10 p. m. or 2. 30 a. m. made no difference. 2. Nearly all “Speed Reading“ courses have a “pacing“some timing device which lets the students know how many words a minute he is reading. You can do this simply by look

21、ing at your watch every 5 or 10 minutes and noting down the page number you have reached. 3. Obviously there is little point in increasing your reading speed if you do not understand what you are reading. If you find you have lost the thread of the story, or you cannot remember clearly the details o

22、f what was said, re-read the section or chapter. 4. Take four or five pages of an interesting book you happen to be reading at the time. Read them as fast as you possibly can. Do not bother about whether you understand or not. If you keep doing this “lightning speed“ reading for an extended period o

23、f time, you will usually find that your “normal“ speed has increased. 5. Most paragraphs in an article have a “a topic sentence“ which expresses the central ideas. The opening paragraph often suggests the general direction and content of the piece, while paragraphs that follow expand or support the

24、first. The closing paragraph often summarizes the very essence of what has been said. A. The Organization of an Article B. An Effective Way to Increase Reading Speed C. Set Aside Time Each Day D.

27、 obvious why the muscle cells, blood cells, and brain cells of any one particular vertebrate(脊椎动物) are so different in their structure and composition when the DNA of every one of their cells is identical. This is the key to one of the most exciting areas of modern cell biology. In different cell ty

28、pes, different sets of the total number of genes (genome) (基因组) are expressed. In other words, different regions of the DNA are “active“ in the muscle cells, blood cells, and brain cells. To understand how this difference in DNA activity can lead to differences in cell structure and composition, it

29、is necessary to consider what is often known as the central dogma(法则) of molecular biology: “DNA makes RNA make protein. “ In molecular terms, a gene is that portion of DNA that encodes for a single protein. The dictum“ one gene makes one protein“ has required some modification(改变) with the discover

30、y that some proteins are composed of several different polypeptide(多肽) chains, but the “one gene makes one polypeptide“ rule does hold. DNA Contains the Blueprint for All Cell Proteins. Messenger RNA is a precise copy (transcript) of the coded sequence of nucleic acid bases in DNA, and this message

31、is translated into a unique protein molecule on specialist organelles (ribo-somes) present in the cytoplasm(细胞质) of all cells. Proteins(蛋白质), which are largely made up of carbon(C) ,hydrogen(H), oxygen(O) ,and nitrogen(N) ,are constructed from 20 different, common amino acids. The versatility of pro

32、teins, the workhorse molecules of the cell, stems from the immense variety of molecular shapes that can be created, by linking amino acids together in different sequences. The smaller proteins consist of only a few dozen amino acids, whereas the larger ones may contain in excess of 200 amino acids,

33、all linked together in a linear(线状的) chain by peptide bonds. As the proteins are released from the ribosome(核糖体) ,they fold into unique shapes, under the influence of chemical forces that depend on the particular sequence of amino acids. So the protein primary sequence , encoded in the gene and fait

34、hfully transcribed and translated into an amino acid chain, determines the three-dimensional structure of the emerging molecule. The human body possesses some 30 000 different kinds of proteins and several million copies of many of these. Each plays a specific rolefor example, hemoglobin carries oxy

35、gen in the blood, actin(肌动蛋白) and myosin(肌球蛋白) interact to generate muscle movement, and acetylcholine (乙酸胆碱) receptor molecules mediate chemical transmission between nerve and muscle cells. EnzymesProtein Biocatalysts An essential group of proteinsthe enzymes (酵素)act as biological catalysts (催化剂) a

36、nd regulate all aspects of cell metabolism (新陈代谢). They enable breakdown of high-energy food molecules (carbohydrates) to provide energy for biological reactions, and they control the synthetic pathways that result in the generation of lipids(e.g., fats, cholesterol(胆固醇), and other vital membrane(膜)

37、 components), carbohydrates (碳水化合物) (sugars, starch (淀粉) , and cellulose (纤维素) , the key components of plant cell walls) ,and many vital small biomolecules essential for cell function. （分数：-1.00）(1).The best title of this passage is_.（分数：-0.20）A.Dongma, DNA and EnzymesB.Dogma, Proteins and Biocataly

Smoking one or t

42、wo cigars a day doubles the risk of cancers of the lip, tongue, mouth, and throat, according to a government study. Daily cigars also increase the risk of lung cancer and cancer of the esophagus, and increase the risk of cancer of the larynx (voicebox) sixfold, say researchers at the National Cancer

43、 Institute in Bethesda, Maryland. In addition, the report revealed that smoking three or four cigars a day increased the risk of oral cancer to 8.5 times the risk for nonsmokers and the risk of esophageal cancer by four times the risk of nonsmokers. The health effects of smoking cigars is one of eig

44、ht sections of the article “ Cigars: Health Effects and Trends“. The researchers report that, compared with a cigarette, a large cigar emits up to 90 times as much carcinogenic tobacco-specific nitrosamines “This article provides clear and invaluable information about the disturbing increase in ciga

45、r use and the significant public health consequences for the country,“ said Dr. Richard Klausner, director of the National Cancer Institute, in a statement. “The data are clear-the harmful substances and carcinogens in cigar smoke, like cigarettes, are associated with the increased risks of several

46、kinds of cancers as well as heart and lung diseases,“ he added. “ In other words, cigars are not safe alternatives to cigarettes and may be addictive. “ “To those individuals who may be thinking about smoking cigars, our advices is dont. To those currently smoking cigars, quitting is the only way to

47、 eliminate completely the cancer, heart and lung disease risks,“ warned Klausner. According to a National Cancer Institute press release, there havent been any studies on the health effects on nonsmokers at cigar social events, but “. a significant body of evidence clearly demonstrates an increased

48、lung cancer risk from secondhand smoke. “ （分数：-1.00）(1).According to the report, smoking three or four cigars a day_.（分数：-0.20）A.increases the risk of oral cancer for non-smokers.B.greatly increases the risk of oral cancer for smokers.C.increases the risk of more than one cancer for non-smokers.D.gr
