The New Grading System in Our School
In order to help students develop their abilities in all fields, our school now has asked the teachers to make some changes in the grading system. This chart shows how it works.
阅读表达(共五小题，每小题2分，满分10分)
阅读下面短文并回答问题，然后将答案写到相应的位置上(请注意问题后的词数要求)。
[1]Cooking carrots whole before chopping them up increases their anti-cancer properties by 25 percent, researchers say.
[2]Leaving the vegetable intact (完整的) prevents valuable nutrients from being easily washed away into water. They can then be chopped up once cooked without loss of nutrients.
[3]Carrots have long been prized for their health benefits, especially their vitamin and fiber content. They contain huge amounts of carotenoids（类胡萝卜素）which are converted into vitamin A in the body. They are also an excellent source of the anti-cancer compound falcarion (镰叶芹醇). In a previous study, Dr Kirsten Brandt found rats fed on a diet containing carrots or isolated falcarino were less likely to develop tumors than those which were not.
[4]They also found that carrots boiled before they were cut contained 25 percent more falcarino than those that were chopped up first. Carrots which are cut have a higher surface area in contact with water, resulting in greater loss of nutrients, compared with boiling them whole. The heat softens the cell walls in the vegetable, allowing vitamins and falcarino to leach (过滤)out.
[5]Dr Brandt said, "The great thing about this is that it's a simple way for people to increase their uptake of a compound, which is good for you. All you need is a bigger saucepan. Naturally occurring sugars, responsible for giving the carrots its sweet flavor, were also found in higher concentration in carrots that had been cooked whole."
[6]The team also carried out a taste on almost 100 volunteers comparing carrots boiled before being cut and some that are cut up first. More than 80 percent of volunteers said that carrots cooked whole tasted much better.
[7]Boiling carrots whole appears to help them keep more of the nutrients. This is really a piece of good news because the method is of great value. Some other vegetables, such as parsnips (欧洲萝卜) which are from the same family and have a roughly similar size and texture can also be more nutritious by ____.

Water problems in the future will become more intense and more complex. Our increasing population will tremendously increase urban wastes, primarily sewage. On the other hand, increasing demands for water will decrease substantially the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce larger volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever - increasing quantities of agricultural chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem.
There are two ways by which this pollution problem can be dwindled(减少). The first relates to the treatment of wastes to decrease their pollution hazard . This involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes, or effluents, to permit the reuse of the water or minimize pollution upon final disposal .
A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement. Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Effluents from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are potential economic uses for waste products.

A．to alert the reader to the dwindling water supply
B．to explain industrial uses of water
C．to acquaint the reader with water pollution problems
D．to demonstrate various measures to solve the pollution problem
2.Which of the following points is NOT included in the passage?
A．Industrial development includes the simplification of complex chemical processes.
B．Diluting wastes needs certain amount of water.
C．Demands for water will go up along with the expanding population .
D．Intensive cultivation of land require more and more chemicals.
3.The reader can conclude that _________.
A．countries of the world will work together on pollution problems
B．byproducts from wastes lead to a more prosperous marketplace
C．science is making great progress in increasing water supplies
D．some industries are now making economic use of wastes
4.The author gives substance to the passage through the use of________.
A．interviews with authorities in the field of water controls
B．opinions and personal observations
C．definitions which clarify important terms
D．strong arguments and persuasions
5.The underlined words "prior to"(para. 2)probably man________.
A．after B．during C．before D．beyond
