24.Which of the following is not mentioned in the third paragraph?
4. Using medicines derived from plants is a practice probably as old as humankind itself. Prehistoric peoples likely noted when consuming a particular plant part provided relief, such as willow bark "tea" lowering a fever. Sumatran (苏门答腊的) clay tablets engraved forty centuries ago list plant-based remedies for common ills, as do ancient writings from Egypt and China. In nineteenth-century United States, St. John's wort Echinacea were just two of many commonly used herbal remedies.Many modern medicines are synthetic versions of plant-derived "natural products." A compound from a periwinkle plant, for example, served as the basis for a powerful drug that fights leukemia (白血病). Poppies provide alkaloids such as morphine that are potent painkillers.In the U.S. today, one-third of all adults have tried herbal treatments, creating a multibillion-dollar market. The resurgence of interest in herbal medicine is largely due to the Dietary Supplements Health Education Act (DSHEA. of 1994, which expanded the definition of "dietary supplement" beyond essential nutrients to include "herbs botanicals," thus removing them from regulation as drugs. This designation means that labels can only mention ways that the herbal product can promote health, not cure disease. For example, valerian root "promotes restful sleep," St. John's wort "may help enhance mood," and Echinacea goldenseal "may help support the immune system." Many physicians biochemists argue that active ingredients in many herbal remedies are indeed drugs, should be regulated as such.It is wise to consult a physician when considering use of an herbal product. Even for a well-understood remedy such as cranberry extract, additional therapy may be required, or drug interactions a possibility. The law may not currently consider herbal ingredients to be drugs, but science indicates otherwise.

22.There is no doubt that new technologies will also play an important role in language teaching in the twenty-first century. Indeed, the use of technology in foreign language learning has constituted another important revolutionary movement in our discipline (学科）in the last half of the twentieth century. Although it has clearly not been a methodological revolution，technological innovation has played an important role in the recent history of language teaching and is bound to have a profound effect on the way that languages are taught in the future. Beginning with the introduction of filmstrips, audiotapes, and language labs in “direct method” and “audiolingual” classroom over forty years ago, technological innovation has moved from the increased use of cassette tapes, videotapes, and overhead projectors and cameras in the past several decades to the introduction of CD-ROMs and the Internet in the 1990s. The possibilities for computer-enhanced language teaching have most recently been explored in distance education programs as well as in the use of local area networks, computer-assisted reading programs, and web-based classroom activities.Though the use of technology is nothing new in foreign language teaching, its exact role in the curriculum is still being assessed and questioned, particularly in light of the rapidly changing nature of technological aids to instruction. Rather than seeing technology as just another ancillary (助手） to be added to our teaching devices, we need to evaluate its potential for enhancing classroom learning as well as for facilitating (使……便利）student-centered, independent learning outside the classroom. In using technological aids and computer-mediated (计算机为中介的）materials in instruction, we also need to bear in mind the level of proficiency of our students and their ability to benefit from the materials that can be used for them. The use of authentic materials is going to be discussed in more detail in a later section of this chapter and in subsequent chapters.(10分)22.1 This passage is mainly about____.(2分)A. the role technology plays in foreign language learningB. the role technology plays in foreign language teachingC. the role computer plays in language learning and language teachingD. the role technology plays in foreign language learning and teaching
23.4 Which of the following can serve as the best title for this passage?
22. Love really is blind when it comes to physical flaws, it would seem.A research conducted by Social studies Center in University of Hawaii at Manoa suggests that when we love someone, we tend to overlook their crooked noses, big tummies or other attributes that might put others off. As a result, husbands and wives think their other halves are more attractive than they really are. No wonder Chinese has the saying that “Beauty lies in the beholder’s eyes”. This phenomenon could also help explain some physically mis-matched couples such as the glamorous Beyonce and Jay-Z, the striking Lara Stone and David Walliams.The so-called “positive illusion” theory comes from an experiment in which researchers asked 70 couples to rate their other halves for attractiveness. Questions included how attractive their husband, wife, boyfriend or girlfriend was to the opposite sex, and how they rated compared with others of the same age. The answers were kept secret to prevent any partners from being upset and distressed. Some of those taking part also rated photos of their partners. In addition, members of the public judged the looks of all 140 men and women taking part.The results revealed that couples view their other halves as being better looking than they really are. Even asking them to rate pictures of their partners did not give them a reality check, the Journal of Social and Personal Relationships reports.With previous studies finding that we view our loved ones as being kinder and more intelligent than they actually are, it does seem that love is blind in all sorts of ways. Those studied were young and had been together on average for just two and a half years. The researchers said that more work was needed to see if those in long marriages were still blind to their partner’s physical flaws.

When people are in love, they are unable to see things that are obvious to others.B. People in love tend to be unaware of physical weakness of their partners. C. To those who are physically weak, they do not notice love.D. When speaking of physical flaws, love is not reasonable.
23.How can we get rid of garbage? Do we have enough energy sources to meet our future energy needs? These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time.They suggest using garbage as an energy source,and at the some time it can save the land to hold garbage. For a long time, people buried garbage or dumped (倾倒) it on empty land. Now, empty land is scarce.But more and more garbage is produced each year.However, garbage can be a good fuel to use.The things in garbage do not look like coal, petroleum, or natural gas;but they are chemically similar to these fossil(化石) fuels.As we use up our fossil fuel supplies, we might be able to use garbage as an energy source. Burning garbage is not a new idea.Some cities in Europe and theUnited States, have been burning garbage for years.The heat that is produced by burning garbage is used to boil water.The steam that is produced is used to make electricity or to heat nearby buildings. In Paris France, some power plants burn almost 2 million metric tons of the cities garbage each year.The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil. Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs.This method could also reduce the amount of garbage piling up on the earth.23.1 What two problems can man solve by burning garbage?A.The shortage of energy and air pollutionB.The shortage of energy and the land to hold garbageC.Air pollution and the shortage of fossil fuelD.Air pollution and the shortage of land to hold garbage
