The Prime Minister's comments yesterday on education spending miss the point, as the secondary education system also needs a major overhaul. Firstly, the system only views the weakest learners as having special (1)...... The brightest and most (2)....... students are not encouraged to develop to their full potential. Secondly, there's too much testing and not enough learning. My fifteen-year-old daughter, for example, has just spent the last month or so (3)_____ for exams. These aren't even real, important exams, as her GCSEs will be next year. They're just (4)....  exams. Is the work she's been doing really going to make her more (5)..... about her subjects, or will she forget it all tomorrow? I suspect the latter. Thirdly, the standard (6)_____ doesn't give students any (7)....... in developing practical work-related, living and social skills, or in skills necessary for higher education. How many students entering university have the first idea what the difference is between (8)....... someone else's work and making good use of someone else's ideas? Shouldn't they have been taught this at school? How many of them are really able to go about (9).......a  skill that's essential at university because there are no teachers to tell you what to do - in an efficient way? Indeed, hoe many students (10)....... from university totally unable to spell even simple English words correctly? The system is letting our children down.

One of the most important (1) _______ of a standardized test is time. You'll only be allowed a certain number of minutes for each section, so it is very important that you use your time (2) _______. The most important time strategy is pacing yourself. Before you begin, take just a few seconds to survey the test, noting the number of questions and the sections that looks easier than the rest. Then, make a rough time schedule based on the amount of time (3) _______ to you. Mark the halfway point on your test and make a note beside that mark of the time when the testing period is half over. Once you begin the test, keep moving. If you work slowly in an attempt to make fewer mistakes, your mind will become bored and begin to wander. You'll end up making far more mistakes if you're not concentrating. If you take too long to answer questions that stump you, you may end up (4) _______ out of time before you finish. So don't stop for difficult questions. Skip them and move on. You can come back to them later if you have time. A that takes you five seconds to answer counts as much as one that takes you several minutes, so pick up the easy points first. (5) _______, answering the easier questions first helps build your confidence and gets you in the testing groove. If you're a little ahead, you know you're on track and may even have a little time left to check your work. If you're a little behind, you have several choices. You can pick up the pace a little, but do this only if you can do it comfortably.

Read the following passage and choose the best answer (A, B, C, D):
There are three valid arguments to support the preservation of endangered species. Aesthetic justification contends that biodiversity contributes to the quality of life because many of the endangered plants and animals are particularly appreciated for their unique physical beauty. The aesthetic role of nature in all its diverse forms is reflected in the art and literature of every culture attaining symbolic status in the spiritual life of many groups. According to the proponents of the aesthetic argument, people need nature in all its diverse and beautiful forms as part of the experience of the world. Another argument that has been put forward, especially by groups in the medical and pharmacological fields, is that of ecological self-interest. By preserving all species, we retain a balance of nature that is ultimately beneficial to humankind. Recent research on global ecosystems has been cited as evidence that every species contributes important or even essential functions that may be necessary to the survival of our own species. Some advocates of the ecological argument contend that important chemical compounds derived from rare plants may contain the key to a cure for one of the diseases currently threatening human beings. If we do not protect other species, then they cannot protect us. Apart from human advantage in both the aesthetic and ecological arguments, the proponents of a moral justification contend that all species have the right to exist, a viewpoint stated in the United Nations World Charter for Nature, created in 1982. Furthermore, if humankind views itself as the stewards of all the creatures on Earth, then it is incumbent upon human beings to protect them, and to ensure the continued existence of all species. Moral justification has been extended by a movement called “deep ecology,” the members of which rank the biosphere higher than people because the continuation of life depends on this larger perspective. To carry their argument to its logical conclusion, all choices must be made for the biosphere, not for people.

The human criterion for perfect vision is 20/20 for reading the standard lines on a Snellen eye chart without a hitch. The score is determined by how well you read lines of letters of different sizes from 20 feet away. But being able to read the bottom line on the eye chart does not approximate perfection as far as other species are concerned. Most birds would consider us very visually handicapped. The hawk, for instance, has such sharp eyes that it can spot a dime on the sidewalk while perched on top of the Empire State Building.
It can make fine visual distinctions because it is blessed with one million cones per square millimeter in its retina. And in water, humans are farsighted, while the kingfisher, swooping down to spear fish, can see well in both the air and water because it is endowed with two foveae - areas of the eye, consisting mostly of cones, that provide visual distinctions. One fovea permits the bird, while in the air, to scan the water below with one eye at a time. This is called monocular vision. Once it hits the water, the other fovea joins in, allowing the kingfisher to focus both eyes, like binoculars, on its prey at the same time.
A frog’s vision is distinguished by its ability to perceive things as a constant motion picture. Known as “bug detectors”, a highly developed set of cells in a frog’s eyes responds mainly to moving objects. So, it is said that a frog sitting in a field of dead bugs wouldn’t see them as food and would starve. The bee has a “compound” eye, which is used for navigation. It has 15,000 facets that divide what it sees into a pattern of dots, or mosaic. With this kind of vision, the bee sees the sun only as a single dot, a constant point of reference. Thus, the eye is a superb navigational instrument that constantly measures the angle of its line of flight in relation to the sun. A bee’s eye also gauges flight speed. And if that is not enough to leave our 20/20 “perfect vision” paling into insignificance, the bee is capable of seeing something we can’t - ultraviolet light.
Thus, what humans consider to be “perfect vision” is in fact rather limited when we look at other species. However, there is still much to be said for the human eye. Of all the mammals, only humans and some primates can enjoy the pleasures of color vision.

According to the passage, “bug detectors” are useful for     .

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.
Together, the thousands of scientists and conservation organizations that contribute to the International Union for Conservation of Nature (IUCN) Red List and other systems of assessment provide the world's largest knowledge base on the global status of species. The aim of these systems is to provide the general public, conservationists, nongovernmental organizations, the media, decision makers, and policy makers with comprehensive and scientifically rigorous information on the conservation status of the world's species and the threats that drive the observed patterns of population decline. Scientists in conservation and protected area management agencies use data on species status in the development of conservation planning and prioritization, the identification of important sites and species for dedicated conservation action and recovery planning, and educational programs. Although the IUCN Red List and other similar species-assessment tools do not prescribe the action to be taken, the data within the list are often used to inform legislation and policy and to determine conservation priorities at regional, national, and international levels. In contrast, the listing criteria of other categorization systems (such as the United States Endangered Species Act, the CITES) are prescriptive; they often require that landowners and various governmental agencies take specific mandatory steps to protect species falling within particular categories of threat It is likely that many undescribed or unassessed species of plants, animals, and other organisms have become or are in the process of becoming extinct. To maintain healthy populations of both known and unknown species, assessments and reassessments are valuable tools. Such monitoring work must continue so that the most current knowledge can be applied to effective environmental monitoring and management efforts. For many threatened species, large well-protected conservation areas (biological reserves) often play major roles in curbing population declines. Such reserves are often cited by conservation biologists and other authorities as the best way to protect individual species as well as the ecosystems they inhabit. In addition, large biological reserves may harbor several undescribed and unassessed species. Despite the creation of several large reserves around the world, poaching and illegal trafficking plague many areas. Consequently, even species in those areas require continued monitored and periodic assessment.
