Scientists have 13 a protein in the body, SIRT-2, as one that seems to 14 . Researchers have managed to increase life spans by up to 40 percent in fruit flies, yeast and worms by stimulating the over-production of SIRT-2. Conversely, reductions in the protein have shortened the organisms' life spans.
Scientists think they may be close to understanding how SIRT-2 works and, potentially, how it 15 to help humans live longer.

请根据需要填入Script：
Prices determine how resources are to be used. They are also the means by which products and services that are in limited supply are rationed among buyers. The price system of the United States is a very complex network composed of the prices of all the products bought and sold in the economy as well as those of a myriad of services, including labor, professional transportation, and public-utility services. The interrelationships of all these prices make up the "system" of prices. The price of any particular product or service is linked to a broad, complicated system of pric es in which everything seems to depend more or less upon everything else.
If one were to ask a group of randomly selected individuals to define "price", many would reply that price is an amount of money paid by the buyer to the seller of a product or service or, in other words, that price is the money value of a product or service as agreed upon in a market transaction. This definition is, of course, valid as far as it goes. For a complete understanding of a price in any particular transaction, much more than the amount of money involved must be known. Both the buyer and seller should be familiar with not only the money amount, but with the amount and quality of the product or service to be exchanged, the time and place at which the exchange will take place and payment will be made, the form of money to be used, the credit terms and discounts that supply to the transaction, guarantees on the product or service, delivery terms, return privileges, and other factors. In other words, both buyer and seller should be fully aware of all the factors that comprise the total "package" being exchanged for the asked-for amount of money in order that they may evaluate a given price.
21.Which of the following is the best title of the passage?
A.Delivery Terms in Transactions
B.The Inherent Weakness of the Prices System
C.The Complexities of the Prices System
D.Market Transaction

However important we may regard school life to be, there is no gainsaying the fact that children spend more time at home than in the classroom. Therefore, the great influence of parents cannot be ignored or discounted by the teacher. They can become strong allies of the school personnel or they can consciously or unconsciously hinder and thwart curricular objectives.
Administrators have been aware of the need to keep parents apprised of the newer methods used in schools. Many principals have conducted workshops explaining such matters as the reading readiness program, manuscript writing and developmental mathematics.
Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The informal tea and many interviews carried on during the year, as well as new ways of reporting pupils' progress, can significantly aid in achieving a harmonious interplay between school and home.
To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent sublimate his natural paternal interest into productive channels. He might be persuaded to let Junior participate in discussing the family budget, buying the food, using a yardstick or measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis.
If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in mathematics, and at the same time, enjoying the work.
Too often however, teachers' conferences with parents are devoted to petty accounts of children's misdemeanors, complaints about laziness and poor work habits, and suggestion for penalties and rewards at home.
What is needed is a more creative approach in which the teacher, as a professional advisor, plants ideas in parents' minds for the best utilization of the many hours that the child spends out of the classroom.
In this way, the school and the home join forces in fostering the fullest development of youngsters' capacities.
26.With what topic is the passage primarily concerned?
A.Teachers play an important role in enlightening parents.
B.Home training is more important than school training because a child spends too many hours with his parents.
C.There are many ways in which the mathematics program can be implemented at school.
D.Teachers can and should help parents to understand further the objectives of the school.
