24、kets. For example, whole grains, fried beans, and com oil are health foods. A narrower classification of health food is natural food. This term is used to distinguish between types of the same food. Raw honey is a natural sweetener, whereas refined sugar is not. Fresh fruit is a natural food, but ca
25、nned fruit, with sugars and other additives, is not. The most precise term of all and the narrowest classification within health foods is organic food, used to describe food that has been grown on a particular kind of farm. Fruit and vegetables that are grown in gardens, that are sprayed only with o
26、rganic fertilizers, that are not sprayed with poisonous insecticides, and that are not refined after harvest, are organic foods. Meat, fish, dairy and poultry products from animals that are fed only organically grown feed and that are not injected with hormones are organic foods.In choosing the type
27、 of food you eat, then, you have basically two choices: inorganic, processed foods, or organic, unprocessed foods. A wise decision should include investigation of the allegations that processed foods contain chemicals, some of which are proven to be toxic, and that vitamin content is greatly reduced
28、 in processed foods.Bread is typically used by health food advocates as an example of a processed food. First, the seeds from which the grain is sprayed with a number of very toxic insecticides. After the grain has been made into flour, it is made white with another chemical which is also toxic. Nex
29、t a dough conditioner is added, along with a softener. The conditioner and softener are poisons, and in fact the softener has sickened and killed experimental animals.A very toxic anti-fungal compound, is added to keep the bread from getting moldy.Other foods from the supermarket would show a simila
30、r pattern of processing and preserving. You see we buy our good on the basis of smell, color, and texture, instead of vitamin content, and manufacturers give us what we want, even if it is poisonous. The alternative? Eat health foods, preferable the organic variety.（分数：10.00）(1).Which term is used t

33、he basis of_.（分数：2.00）A.organic varietyB.beautyC.refined contentsD.color and texture(5).What is the main idea of this passage?（分数：2.00）A.Health food.B.The processing of bread.C.Organic gardens.D.Poisons.八、Text 2(总题数：1，分数：10.00)Punctuation makes the written language intelligible. It does the job, on
34、the page, of the changes of pitch, pace and rhythm which make it possible to understand speech. Unsurprisingly, therefore, a requirement for some knowledge of how to punctuate makes an early appearance in an English curriculum.The trouble is, that necessary though punctuation is, the task of teachin
35、g it to children is considerably more challenging than it might appear. For example, it is possible that to instruct children about writing in sentences by telling them about full stops and capital letters is to court frustration and failure. The notion of the sentence as a statementa free- standing
36、 chunk of informationis something that children come to gradually. As written work grows longer and more complicated, so the perception of sentence increases. Good teachers will, in their teaching of early writing, watch for the childs ability to compose in sentences, and then point out how the use
37、of punctuation will define them more clearly.So, where, in all this, comes the mechanical definition of a sentencethat it needs a verb, for example? The pragmatic answer is that it comes nowhere at all. Adult writers do not, on the whole, look back at their sentences to make sure they contain verbs.
38、 We all surely feel our sentences intuitively. Most of the time, to be sure, they will contain verbs. Occasionally, though, they may notand wheres the harm? What is certain is that you cannot possibly use the grammatical rule as a tool with which to teach a seven-year-old about sentence-writing. The
39、 child can be nudged and helped towards writing in sentences, but on the whole he will not do it until he is ready.The point is that punctuation is an aid which the writer brings into play to illuminate an already formed idea. Before you can learn the punctuation, you have to know what you want to p
40、unctuate. Thus you teach capital letters, full stops, question marks and exclamation marks to a child who is already writing sentences, questions and exclamations. The development of a childs writing will always be a step ahead of the punctuation, and to reverse the process in response, say, to the
41、short-term demands of a curriculum is to put later progress at risk.（分数：10.00）(1).Which statement can best sum up the main idea of the passage?（分数：2.00）A.it is necessary to require the knowledge of punctuation in an English curriculum.B.Punctuation is very important in written language.C.Punctuation
42、 can make sentences more clear.D.Punctuation should be taught after the development of childrens writin(2).The author believes that sentences which do not contain a verb are_.（分数：2.00）A.carelessly written sentencesB.useful in teaching punctuationC.not incorrect sentencesD.based on grammar(3).What do
43、es the word “nudged“ (the last sentence, Par（分数：2.00）A.3) probably mean?A. Hindered.B. Removed.C. Encouraged.D. Prevente(4).According to the text, punctuation is naturally used when_.（分数：2.00）A.a writer already knows what he/she means to sayB.a writer needs an aidC.long or complex sentences are writ
44、tenD.writing sentences with question and exclamation marks(5).What, according to the passage, might make a teacher teach punctuation before children have the ability to write sentences?（分数：2.00）A.The demand of a curriculum.B.The demand of parents.C.The need of children.D.The intention to help childr

To conserve is to save and protect, to leave what we ourselves enjoy in such good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than th
46、e supplies of raw materials; most of them, even until very recently, had the foolish idea that the treasures were “limitless“ and “inexhaustible“. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which mean
47、s that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.Fifty years ago nature study was not part of the school work; scientific forestry was anew idea; timber was still cheap because it could be brought in any quantity from distant woodlands
48、; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation“ had nothing of the meaning that it has for us today.For the sake of ourselves and those who will come after us, we must now se
49、t about repairing the mistakes of our forefathers. Conservation should, therefore, be made a part of everyones daily life. To know about the water table in the ground is just as important to us as a knowledge of the basic arithmetic formulas. We need to know why all watersheds need the protection of plant life and why the running current of streams and rivers must be made to yield their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the i
