Orchids are unique in having the most highly developed of all blossoms, in which the usual male and female reproductive organs are fused in a single structure called the column. The column is designed so that a single pollination will fertilize hundreds of thousands, and in some cases millions, of seeds, so microscopic and light they are easily carried by the breeze. Surrounding the column are three sepals and three petals, sometimes easily recognizable as such, often distorted into gorgeous, weird, but always functional shapes. The most noticeable of the petals is called the labellum, or lip. It is often dramatically marked as an unmistakable landing strip to attract the specific insect the orchid has chosen as its pollinator. To lure their pollinators from afar, orchids use appropriately intriguing shapes, colors, and scents. At least 50 different aromatic compounds have been analyzed in the orchid family, each blended to attract one, or at most a few, species of insects or birds. Some orchids even change their scents to interest different insects at different times. Once the right insect has been attracted, some orchids present all sorts of one-way obstacle courses to make sure it does not leave until pollen has been accurately placed or removed. By such ingenious adaptations to specific pollinators, orchids have avoided the hazards of rampant crossbreeding in the wild, assuring the survival of species as discrete identities. At the same time they have made themselves irresistible to collectors.The word "their" in line 12 refers to .......

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questionsTechnology has utterly transformed our ability to communicate with each other. Linking to each other both literally and figuratively, many of us connect through cell phones, email, instant messaging, blogs, and networking web sites, yet we may be less connected to each other than we think. According to a study, Americans are becoming increasingly socially isolated. The study reveals, for example, that one quarter of Americans say that they have no one to discuss important personal issues with, and that the number of close friends that American have has dropped from three to two. Meanwhile, the Boston Globe reports that this spreading isolation is experienced more sharply among those with less education, people of color, and older Americans. Unsurprisingly, those who are young, white, and well educated tend to have stronger social networks. From my own experience I have to say that I’ve never felt more connected, thanks to a web of friends, family, and colleagues. One of my closest friends is someone I met through an online discussion group who lives hundreds of miles away from me. We have met faceto-face only twice, yet our regular electronic correspondence and cell phone calls sustain our close friendship. And, speaking of blogging, my blog has introduced me to people I would never have met otherwise and has led to enduring and important friendships. On the other hand, I recently saw a scene unfold that proved to me how deeply disconnected we as Americans have become. I had just wrapped up a presentation on mediation at a family therapy center. As I was leaving, I noticed a mother and her teenage son who had just completed their session with their family therapist. After making their next appointment, they both took out their cell phones, placed calls, and began loud conversations with whoever was on the other end. I walked out behind them to the parking lot to my car. They both jumped into their SUV, and, as I saw them drive off, they were still talking on their cell phones. But, alas, not to each other. Which of the following has nothing to do with the isolation among Americans?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questionsHarvard University, today recognized as part of the top echelon of the world’s universities, came from very inauspicious and humble beginning. This oldest of American universities was founded in 1636, just sixteen years after the Pilgrims landed at Plymouth. Included in the puritan emigrants to the Massachusetts colony during this period were more than 100 graduates of England’s prestigious Oxford and Cambridge universities, and these universities graduates in the New Word were determined that their sons would have the same educational opportunities that they themselves had had, Because of this support in the colony for an institution of higher learning, the General Court of Massachusetts appropriated 400 pounds for a college in October of 1636 and early the following year decided on a parcel of land for the school; this land was in an area called Newetowne, which was later renamed Cambridge after its English cousin and is the site of t he present-day university. When a young minister named John Harvard, who came from the neighboring town of Charlestowne, died from tuberculosis in 1638, he willed half of his estate of 1,700 pounds to the fledgling college. In spite of the fact that only half of the bequest was actually paid, the General Court named the college after the minister in appreciation for what he had done. The amount of the bequest may not have been large, particularly by today’s standard, but it was more than the General Court had found it necessary to appropriate in order to open the college. Henry Dunster was appointed the first president of Harvard in 1640, and it should be noted that in addition to serving as president, he was also the entire faculty, with an entering freshmen class of four students. Although the staff did expand somewhat, for the first century of its existence the entire teaching staff consisted of the president and three or four tutors The main idea of this passage is that_________.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questionsWe find that bright children are rarely held back by mixed-ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the notso-bright child. After all, it can be quite discouraging to be at the bottom of the top grade! Besides, it is rather unreal to grade people just according to their intellectual ability. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed-ability teaching contributes to all these aspects of learning. In our classroom, we work in various ways. The pupils often work in groups; this gives them the opportunity to learn to co-operate, to share, and to develop leadership skills. They also learn how to cope with the personal problems as well as learning how to think, to make decisions, to analyze and evaluate, to communicate effectively. The pupils learn from each other as well as from the teachers. Sometimes the pupils work in pairs; sometimes the work on individual tasks and assignments, they can do this at their own speed. They also have some formal class teaching when this is appropriate. We encourage our pupils to use the library, and we teach them the skills they need in order to do this effectively. An advanced pupil can do advanced works; it does not matter what age the child is. We expect our pupils to do their best, not their least, and we give them every encouragement to attain this goal.The author’s purpose of writing this passage is to_______.

Read the following passage and mark the letter A , B , C , or D on your answer sheet to indicate the correct answer to each of the questionsThe advent of the Internet may be one of the most important technological developments in recent years . Never before have so many people had access to so many different sources of information . For all of the Internet's advantages , however , people are currently becoming aware of some of its drawbacks and are looking for creative solutions . Among the current problems , which include a general lack of reliability and numerous security concerns , the most crucial is speed .First of all , the Internet has grown very quickly . In 1990 , only a few academics had ever heard of the Internet . In 1996 , over 50 million people used it . Every year , the number of people with access to the Internet doubles . The rapid growth has been a problem . The computer systems which run the Internet have not been able to keep up with the demand . Also , sometimes , a request for information must pass through many routing computers before the information can be obtained . A request for information made in Paris might have to go through computers in New York , Los Angeles and Tokyo in order to obtain the required information . Consequently , the service is often slow and unpredictable. Service also tends to be worse when the Internet is busiest - during the business day of the Western Hemisphere - which is also when companies need its service the most.Some people are trying to harness the power of networked computers in such a way as to avoid this problem . In 1995 , a group of American universities banded together to form what has come to be known as Internet II . Internet II is a smaller , more specialized system intended for academic use . Since it is more specialized , fewer users are allowed access. Consequently , the time required to receive information has decreased . Businesses are beginning to explore a possible analogue to the Internet II . Many businesses are creating their own " Intranets " . These are systems that can only be used by the members of the same company . In theory , fewer users should translate into a faster system . Intranets are very useful for large national and international companies whose branches need to share information . Another benefit of an Intranet is an increased amount of security . Since only company employees have access to the information on the Intranet , their information is protected from competitors . While there is little doubt that the Internet will eventually be a fast and reliable service , industry and the academic community have taken their own steps toward making more practical global networks . In the passage , which following is NOT true of the Internet ?

As it can be inferred from the passage, what benefits does Internet II have over the Internet I?

The word "analogue" in paragraph 5 most nearly means_____.

The word “harness" in paragraph 4 is closest in meaning to .........
